Heating, ventilation, and air conditioning ( HVAC ) is the use of various technologies to control the temperature , humidity , and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality . HVAC system design is a subdiscipline of mechanical engineering , based on the principles of thermodynamics , fluid mechanics , and heat transfer . " Refrigeration " is sometimes added to the field's abbreviation as HVAC&R or HVACR , or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers ).

130-559: The Great Falls Public Schools (also known as School District #1 ) is a public school district which covers the city limits of Great Falls, Montana , in the United States . As of March 2010, it was the second-largest school district in the state of Montana, and the third-largest employer in the city of Great Falls. The district has two components: Great Falls Elementary School District and Great Falls High School District . The National Center for Education Statistics (NCES) code for

260-543: A further education college or sixth form college to prepare themselves for a wide range of apprenticeships and study. Major provider of vocational qualifications include the Business and Technology Education Council , City and Guilds of London Institute and Edexcel . Higher National Certificates and Higher National Diplomas typically require 1 and 2 years of full-time study and credit from either HNE or Diplomas can be transferred toward an undergraduate degree. Along with

390-500: A grammar school if they pass the eleven plus exam ; there are also a number of isolated fully selective grammar schools and a few dozen partially selective schools . The oldest state school in England is Beverley Grammar School , which was founded in 700 AD. The French educational system is highly centralised, organised, and ramified. It is divided into three stages: Schooling in France

520-572: A selective school system where admission is restricted on the basis of selection criteria, usually academic performance. The term is commonly used in relation to England and Wales, where comprehensive schools were introduced as state schools on an experimental basis in the 1940s and became more widespread from 1965. About 90% of English secondary school pupils attend a comprehensive state school. Comprehensive schools provide an entitlement curriculum to all children, without selection whether due to financial considerations or attainment. A consequence of that

650-443: A wind tunnel which has thousands of changes per hour. The highest air change rates are for crowded spaces, bars, night clubs, commercial kitchens at around 30 to 50 air changes per hour. Room pressure can be either positive or negative with respect to outside the room. Positive pressure occurs when there is more air being supplied than exhausted, and is common to reduce the infiltration of outside contaminants. Natural ventilation

780-547: A $ 4 million discrimination claim against GFPS with the Montana Human Rights Commission. On May 19, 2011, the Human Rights Commission ordered the school district to pay $ 150,000 to Schilling for discriminating against her son based on his mental, physical, emotional, and developmental handicaps. GFPS sued to overturn the decision of the Montana Human Rights Commission, and as of September 2014 the appeal

910-480: A $ 98 million, 20-year bond issue on October 4, 2016. The school district proposed to spend $ 20.8 million on infrastructure and $ 16.6 million on new construction at Great Falls High School; $ 4.4 million on infrastructure and $ 6.9 million on new construction at C.M. Russell High School; $ 3.4 million on infrastructure at Paris Gibson Education Center; $ 705,000 on improvements to Memorial Stadium; $ 12.7 million on infrastructure at 20 K-to-8th grade schools; $ 17.5 million razing

1040-487: A building in a high dust environment, or a home with furry pets, will need to have the filters changed more often than buildings without these dirt loads. Failure to replace these filters as needed will contribute to a lower heat exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; low air flow can result in iced-over evaporator coils, which can completely stop airflow. Additionally, very dirty or plugged filters can cause overheating during

1170-729: A building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls. An alternative to packaged systems is the use of separate indoor and outdoor coils in split systems . Split systems are preferred and widely used worldwide except in North America. In North America, split systems are most often seen in residential applications, but they are gaining popularity in small commercial buildings. Split systems are used where ductwork

1300-481: A central location such as a furnace room in a home, or a mechanical room in a large building. The heat can be transferred by convection , conduction, or radiation . Space heaters are used to heat single rooms and only consist of a single unit. Heaters exist for various types of fuel, including solid fuels , liquids , and gases . Another type of heat source is electricity , normally heating ribbons composed of high resistance wire (see Nichrome ). This principle

1430-763: A chair and vice-chair. The Board has formed a number of committees—some of which include board members and many of which do not—which provide advice and expertise to the Board concerning school district operations. These include committees on: Budget, school year calendar, communication, curriculum, employee wellness, English as a second language instruction, curriculum implementation, insurance, labor-management relations, leadership team, staff development (PIR), staff development assessment (Professional Learning Community Time, or PLCT), safety, student wellness, superintendent's cabinet (an administrative leadership team), and technology. A superintendent (chief administrative and executive officer)

1560-549: A circulator, which is a pump, to move hot water through the distribution system (as opposed to older gravity-fed systems ). The heat can be transferred to the surrounding air using radiators , hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat. The use of water as the heat transfer medium is known as hydronics . The heated water can also supply an auxiliary heat exchanger to supply hot water for bathing and washing. Warm air systems distribute

1690-527: A facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware. Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in

1820-470: A fraction of the unit cost of government schools. The teacher to student ratio is usually much lower in private schools than in the government ones, creating more competitive students. Education in India is provided by the public sector as well as the private sector, with control and funding coming from three levels: federal, state, and local. The Nalanda University was the oldest university-system of education in

1950-462: A governmental entity. Private school generally refers to primary, secondary and tertiary educational institutions that are not government-owned. Elementary, middle, and high schools that are operated by a religious organization are commonly called parochial schools , though, in practice, the term is generally used to refer only to schools operated by the Catholic Church or mainline denominations;

2080-410: A heat pump system in which a compressor is used to drive thermodynamic refrigeration cycle , or in a free cooling system that uses pumps to circulate a cool refrigerant (typically water or a glycol mix). It is imperative that the air conditioning horsepower is sufficient for the area being cooled. Underpowered air conditioning systems will lead to power wastage and inefficient usage. Adequate horsepower

2210-416: A heating cycle, which can result in damage to the system or even fire. Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor because

2340-455: A huge difference for the environment and help expand the knowledge of using different methods. HVAC is based on inventions and discoveries made by Nikolay Lvov , Michael Faraday , Rolla C. Carpenter , Willis Carrier , Edwin Ruud , Reuben Trane , James Joule , William Rankine , Sadi Carnot , Alice Parker and many others. Multiple inventions within this time frame preceded the beginnings of

2470-406: A large number of private schools and universities. In the United States , the term "state school" is colloquial for state university , a college, and a university in a state university system. It is also used by state governments in the names of juvenile prisons , and facilities for disabled people. Instead, the term "public school" is used for elementary, middle, and high schools funded or run by

2600-475: A larger district heating (DH) or district cooling (DC) network, or a combined DHC network. In such cases, the operating and maintenance aspects are simplified and metering becomes necessary to bill for the energy that is consumed, and in some cases energy that is returned to the larger system. For example, at a given time one building may be utilizing chilled water for air conditioning and the warm water it returns may be used in another building for heating, or for

2730-416: A part of the free education. With the establishment of the provincial council system in the 1980s the central government handed control of most schools to local governments. However the old schools which had been around since the colonial times were retained by the central government, thus creating three types of government schools: National Schools, Provincial Schools, and Piriven. National Schools come under

2860-401: A pre-school class (mandatory since 2009), the 9-year obligatory course and a voluntary 11th year. It thus caters for pupils aged 6 to 17. It is also possible for parents to send their children to various kinds of private schools . These schools also receive government funding, although they are not public. In addition to this funding, these schools may charge a fee from the parents. England has

2990-656: A report regarding collective bargaining negotiations with the Great Falls Education Association . The board rejected the report without discussion at its public session, at which time the local newspaper, the Great Falls Tribune , sued—arguing the private meeting was a violation of the Article II, Section 9, of the Montana Constitution (a particularly strongly worded provision that gives citizens

3120-494: A room for the purpose of reducing the perceived temperature by increasing evaporation of perspiration on the skin of the occupants. Because hot air rises, ceiling fans may be used to keep a room warmer in the winter by circulating the warm stratified air from the ceiling to the floor. Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and

3250-476: A school that is state-controlled. These are officially called public schools according to the South African Schools Act of 1996, but it is a term that is not used colloquially. The Act recognised two categories of schools: public and independent. Independent schools include all private schools and schools that are privately governed. Independent schools with low tuition fees are state-aided and receive

3380-477: A strong state-funded school system. There are a number of categories of English state-funded schools including academy schools , community schools , faith schools , foundation schools , free schools , grammar schools , maths schools , studio schools, university technical colleges , state boarding schools and City Technology Colleges . About one third of English state-funded schools are faith schools ; i.e. affiliated with religious groups, most often from

3510-520: A subsidy on a sliding-scale. Traditional private schools that charge high fees receive no state subsidy. State schools are all state-owned, including section 21 schools, formerly referred to as "model C" or semi-private schools, that have a governing body and a degree of budget autonomy, as these are still fully owned and accountable to the state. Under the Canadian constitution , public-school education in Canada

3640-608: Is a 12-year compulsory education program from the government. The Indonesian educational system is divided into three stages: Most students attend public schools through the lower secondary level, but private education is popular at the upper secondary and university levels. The first public education system on record was put in place during the Koryo Dynasty. The national school system was put in place under Hak-Je ( Korean :  학제 ; Hanja :  學制 ; lit.  Education Policy) enacted by King Seong Jong, which

3770-403: Is a key factor in reducing the spread of airborne illnesses such as tuberculosis, the common cold, influenza, meningitis or COVID-19. Opening doors and windows are good ways to maximize natural ventilation, which would make the risk of airborne contagion much lower than with costly and maintenance-requiring mechanical systems. Old-fashioned clinical areas with high ceilings and large windows provide

3900-468: Is a provincial responsibility and, as such, there are many variations among the provinces. Junior kindergarten or equivalent exists as an official program in Ontario and Quebec while kindergarten or equivalent is available in every province, but provincial funding and the level of hours provided varies widely. Starting at grade one, at about age six, there is universal Crown-funded access up to grade twelve, or

4030-673: Is a responsibility shared by the national government, the provinces and federal district and private institutions, though basic guidelines have historically been set by the Ministry of Education. Closely associated in Argentina with President Domingo Sarmiento 's assertion that "the sovereign should be educated." The word "sovereign" refers to the people. Education has been extended nearly universally and its maintenance remains central to political and cultural debate. Even though education at all levels, including universities, has always been free, there are

4160-419: Is a wider ranging curriculum, including practical subjects such as design and technology and vocational learning. Technical education in state schools are introduced during the secondary school years and goes on into further education (FE) and higher education (HE). Further education incorporates vocational oriented education as well as a combination of general secondary education. Students can also go on to

4290-410: Is air change rate or air changes per hour : the hourly rate of ventilation divided by the volume of the space. For example, six air changes per hour means an amount of new air, equal to the volume of the space, is added every ten minutes. For human comfort, a minimum of four air changes per hour is typical, though warehouses might have only two. Too high of an air change rate may be uncomfortable, akin to

4420-515: Is also used for baseboard heaters and portable heaters . Electrical heaters are often used as backup or supplemental heat for heat pump systems. The heat pump gained popularity in the 1950s in Japan and the United States. Heat pumps can extract heat from various sources , such as environmental air, exhaust air from a building, or from the ground. Heat pumps transfer heat from outside the structure into

4550-521: Is appointed or elected to co-ordinate the state department of education, the state board of education, and the state legislature. Statewide education policies are disseminated to school districts or their equivalents. They are associated with counties, or with groups of counties, but their boundaries are not necessarily coterminous with county boundaries. The intermediate school districts encompass many local school districts. Local school districts operate with their own local boards, which oversee operations of

4680-877: Is channeled through the space to enhance cooling and ventilation. Cross ventilation is most effective when there are clear, unobstructed paths for airflow within the building. In more complex schemes, warm air is allowed to rise and flow out high building openings to the outside ( stack effect ), causing cool outside air to be drawn into low building openings. Natural ventilation schemes can use very little energy, but care must be taken to ensure comfort. In warm or humid climates, maintaining thermal comfort solely via natural ventilation might not be possible. Air conditioning systems are used, either as backups or supplements. Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate. An important component of natural ventilation

4810-413: Is essentially a daycare facility. French secondary education is divided into two schools: The completion of secondary studies leads to the baccalauréat . The baccalauréat (also known as bac ) is the end-of- lycée diploma students sit for in order to enter university , a Classe préparatoire aux grandes écoles , or professional life. The term baccalauréat refers to the diploma and

4940-463: Is hired by the board and oversees daily operation of the school system and the implementation and assessment of board policies and decisions. In 2009, the school district began facing major civil and criminal complaints about its treatment of special needs children. That year, Tifonie Schilling alleged that two special education paraprofessionals and a special education teacher at North Middle School had physically abused her son. An investigation by

5070-520: Is increasingly common in which the elementary school contains kindergarten or 1st grade to 5th or 6th grade and the middle School contains 6th or 7th and 8th grade. In addition, some elementary schools are splitting into two levels, sometimes in separate buildings: elementary school (usually K–2) and intermediate (3–5). Some middle schools are different. The K–8 format is also an emerging popular concept in which students may attend only two schools for all of their K–12 education. Many charter schools feature

5200-478: Is inexpensive. Natural ventilation is not practical in much of the infrastructure because of climate. This means that the facilities need to have effective mechanical ventilation systems and or use Ceiling Level UV or FAR UV ventilation systems. Ventilation is measured in terms of Air Changes Per Hour (ACH). As of 2023, the CDC recommends that all spaces have a minimum of 5 ACH. For hospital rooms with airborne contagions

5330-499: Is known as room air distribution . In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify

5460-441: Is mandatory as of age three. Primary education takes place in kindergarten ( école maternelle ) for children from 3 to 6 and ( école élémentaire ) from 6 to 11. For public schools, both schools building and administrative staff are managed by the borough's ( commune ) while professors are ( Education nationale ) civil servants. Some children even start earlier at age two in pré-maternelle or garderie class, which

5590-581: Is needed to improve the performance of ventilation in terms of ... In scenarios where outdoor pollution would deteriorate indoor air quality, other treatment devices such as filtration may also be necessary. Methods for ventilating a building may be divided into mechanical/forced and natural types. Mechanical, or forced, ventilation is provided by an air handler (AHU) and used to control indoor air quality. Excess humidity , odors, and contaminants can often be controlled via dilution or replacement with outside air. However, in humid climates more energy

5720-450: Is not feasible or where the space conditioning efficiency is of prime concern. The benefits of ductless air conditioning systems include easy installation, no ductwork, greater zonal control, flexibility of control, and quiet operation. In space conditioning, the duct losses can account for 30% of energy consumption. The use of minisplits can result in energy savings in space conditioning as there are no losses associated with ducting. With

5850-602: Is provided to a large extent by the government, with control coming from state level, ( Länder ) and funding coming from two levels: federal and state. Curricula, funding, teaching, and other policies are set through the respective state's ministry of education. Decisions about the acknowledgment of private schools (the German equivalent to accreditation in the US) are also made by these ministries. However, public schools are automatically recognised, since these schools are supervised directly by

5980-467: Is renewable for four years. The Astrin donation also funded a $ 10,000 annual grant to support students in dual-credit classes. The Astrin bequest was the largest donation the GFPSF history. State school A state school , public school , or government school is a primary or secondary school that educates all students without charge. They are funded in whole or in part by taxation and operated by

6110-436: Is required for any air conditioner installed. The refrigeration cycle uses four essential elements to cool, which are compressor, condenser, metering device, and evaporator. In variable climates, the system may include a reversing valve that switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows

6240-458: Is required to remove excess moisture from ventilation air. Kitchens and bathrooms typically have mechanical exhausts to control odors and sometimes humidity. Factors in the design of such systems include the flow rate (which is a function of the fan speed and exhaust vent size) and noise level. Direct drive fans are available for many applications and can reduce maintenance needs. In summer, ceiling fans and table/floor fans circulate air within

6370-574: Is the Education Act of 1996. Education may be obtained from government-sponsored schools, private schools , or through homeschooling . By law, primary education is compulsory . As in other Asian countries such as Singapore and China, standardised tests are a common feature. Philippines has had a public education system since 1863 and is the oldest in Asia. It was created during the Spanish colonization of

6500-497: Is the process of changing or replacing air in any space to control the temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen. It plays a critical role in maintaining a healthy indoor environment by preventing the buildup of harmful pollutants and ensuring the circulation of fresh air. Different methods, such as natural ventilation through windows and mechanical ventilation systems , can be used depending on

6630-408: Is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases. Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of

6760-599: The série littéraire (L) focuses on French and foreign languages and philosophy . The Grandes écoles of France are higher education establishments outside the mainstream framework of the public universities . They are generally focused on a single subject area, such as engineering , have a moderate size, and are often quite (sometimes extremely) selective in their admission of students. They are widely regarded as prestigious, and traditionally have produced most of France's scientists and executives . Education in Germany

6890-675: The Church of England (approximately 2/3 of faith schools), or the Roman Catholic Church (around 3/10). There are also schools affiliated to other Christian churches; in 2011, there were 42 Jewish, 12 Muslim, 3 Sikh and 1 Hindu faith schools. These faith schools include sub-categories such as faith- academy schools , voluntary aided schools , and voluntary controlled schools : most voluntary controlled schools are faith schools. All of these are funded through national and local taxation. All state-funded schools in England are required to follow

7020-481: The National Curriculum , which is made up of twelve subjects. Every state school must offer a curriculum which is balanced and broadly based and which promotes the spiritual, moral, cultural, mental and physical development of pupils at the school and of society, and prepares pupils at the school for the opportunities, responsibilities and experiences of later life. For each of the statutory curriculum subjects,

7150-638: The Secretary of State for Education is required to set out a Programme of Study which outlines the content and matters which must be taught in those subjects at the relevant Key Stages. Teachers should set high expectations for every pupil. They should plan stretching work for pupils whose attainment is significantly above the expected standard. Teachers should use appropriate assessment to set targets which are deliberately ambitious. A high number of state-funded secondary schools are specialist schools , receiving extra funding to develop one or more subjects in which

7280-568: The dew point , moisture in the air condenses on the evaporator coil tubes. This moisture is collected at the bottom of the evaporator in a pan and removed by piping to a central drain or onto the ground outside. A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at dehumidifying

7410-407: The government of the state. State-funded schools are global with each country showcasing distinct structures and curricula. Government-funded education spans from primary to secondary levels, covering ages 4 to 18. Alternatives to this system include homeschooling , private schools , charter schools , and other educational options. In South Africa , a state school or government school refers to

7540-452: The states are also referred to as "public". However, unlike public high schools, public universities usually charge tuition, but fees are usually much lower than those charged by private universities , particularly for students who meet in-state residency criteria. Community colleges , state colleges , and state universities are examples of public institutions of higher education. In particular, many state universities are regarded as among

7670-514: The 1990s, the school system began devolving responsibility for school policy and operations to the local schools, and struggled with finding the right balance between centralization and decentralization. In 1992, the school system was involved in an open records lawsuit that went all the way to the Montana Supreme Court . On September 10, 1990, the GFPS board of trustees met privately to discuss

7800-421: The CDC recommends a minimum of 12 ACH. The challenges in facility ventilation are public unawareness, ineffective government oversight, poor building codes that are based on comfort levels, poor system operations, poor maintenance, and lack of transparency. UVC or Ultraviolet Germicidal Irradiation is a function used in modern air conditioners which reduces airborne viruses , bacteria , and fungi , through

7930-738: The GFPS school board began studying making major repairs and upgrades to all the school system buildings at a potential cost of more than $ 100 million. To accommodate increasing enrollment, Paris Gibson Education Center and West Elementary School might be turned back into middle schools. Other projects considered included upgrading the HVAC and drinking water/sewer systems at both high schools, adding an all-purpose fieldhouse to C.M. Russell High School, and replacing Longfellow Elementary School. The board also said it would also consider closing some schools. After nearly 18 months of public discussions, plan revisions, and architectural planning, voters were asked to approve

Building permits and code-compliance inspections of the installations are normally required for all sizes of buildings Although HVAC is executed in individual buildings or other enclosed spaces (like NORAD's underground headquarters), the equipment involved is in some cases an extension of

8580-494: The K-8 format in which all elementary grades are housed in one section of the school, and the traditional junior high school students are housed in another section of the school. Some very small school districts, primarily in rural areas, still maintain a K–12 system in which all students are housed in a single school. A few 7–12 schools also exist. In the United States, institutions of higher education that are operated and subsidised by

8710-497: The Ministry of Education. The Danish school system is supported today by tax-based governmental and municipal funding from day care through primary and secondary education to higher education and there are no tuition fees for regular students in public schools and universities . The Danish public primary schools , covering the entire period of compulsory education, are called folkeskoler (literally 'people's schools' or 'public schools'). The folkeskole consists of

8840-533: The Montana Supreme Court upheld the appellate court, concluding, "The collective bargaining strategy exception is an impermissible attempt by the Legislature to extend the grounds upon which a meeting may be closed." In 2012, the Great Falls Public Schools received a $ 10,000 "Graduation Matters" grant from the state Office of Public Instruction as part of a program to lower the city's dropout rate. The grant

8970-924: The National Board Curriculum. Many children, especially girls, drop out of school after completing the 5th Year in remote areas. In larger cities such as Dhaka and Chittagong , however, this is fairly uncommon. Many good public schools conduct an entrance exam, although most public schools in the villages and small towns usually do not. Public schools are often the only option for parents and children in rural areas, but there are large numbers of private schools in Dhaka and Chittagong. Many Bangladeshi private schools teach their students in English and follow curricula from overseas, but in public schools lessons are taught in Bengali . In China, state schools are funded and administered by

9100-465: The United States, 88% of students attend public schools, compared with 9% who attend parochial schools , 1% who attend private independent schools , and 2% who are homeschooled . Public school is normally split up into three stages: elementary school ( kindergarten to 5th or 6th grade), middle ("intermediate" or junior high school) from 5th, 6th, or 7th grade to 8th or 9th grade, and high school (9th or 10th to 12th grade). The middle school format

9230-480: The additional fees. Some parents appreciate the idea as they may send their children to good schools even though they may not be academically qualified, while others believe that it is not fair for someone who has a background of poverty. The public spending on schools in China has been uneven due to insufficient investment in education. This condition is in favor of urban schools and it is promoted by past policies such as

9360-579: The age of sixteen in most provinces, while students in Ontario and New Brunswick must attend schools until the age of 18. Some Canadian provinces offer segregated-by-religious-choice, but nonetheless Crown-funded and Crown-regulated, religiously based education. In Ontario, for example, Roman Catholic schools are known as "Catholic Schools" or "Separate Schools", not "Public Schools", although these are, by definition, no less "public" than their secular counterparts. In some countries, such as Brazil and Mexico ,

9490-433: The air inside. Initially, heat pump HVAC systems were only used in moderate climates, but with improvements in low temperature operation and reduced loads due to more efficient homes, they are increasing in popularity in cooler climates. They can also operate in reverse to cool an interior. In the case of heated water or steam, piping is used to transport the heat to the rooms. Most modern hot water boiler heating systems have

9620-484: The architecture permits. ASHRAE defined Natural ventilation as the flow of air through open windows, doors, grilles, and other planned building envelope penetrations , and as being driven by natural and/or artificially produced pressure differentials. Natural ventilation strategies also include cross ventilation , which relies on wind pressure differences on opposite sides of a building. By strategically placing openings, such as windows or vents, on opposing walls, air

9750-704: The best institutions of higher education in the US but usually are surpassed in ranking by certain private universities and colleges, such as those of the Ivy League , which are often very expensive and extremely selective in the students they accept. In several states, the administrations of public universities are elected via the general electoral ballot. Public or Government-funded schools are found throughout Bangladesh . They are referred to as 'Government High School'. These schools mostly teach students from Year 1 to 10, with examination for students in year 10. All public schools follow

9880-483: The blood, forming carboxyhemoglobin, reducing the blood's ability to transport oxygen. The primary health concerns associated with carbon monoxide exposure are its cardiovascular and neurobehavioral effects. Carbon monoxide can cause atherosclerosis (the hardening of arteries) and can also trigger heart attacks. Neurologically, carbon monoxide exposure reduces hand to eye coordination, vigilance, and continuous performance. It can also affect time discrimination. Ventilation

10010-440: The building design and air quality needs. Ventilation often refers to the intentional delivery of the outside air to the building indoor space. It is one of the most important factors for maintaining acceptable indoor air quality in buildings. Although ventilation is an integral component of maintaining good indoor air quality, it may not be satisfactory alone. A clear understanding of both indoor and outdoor air quality parameters

10140-517: The city opened the Whittier Building (later known as Whittier Elementary School) and began holding ungraded educational instruction for all students there. Great Falls High School , the city's first high school, was founded in the fall of 1890 by the city of Great Falls after four teenage girls (newly arrived in the city) asked to receive a high school public education. "Junior High School", later known as Largent Elementary School, opened in 1918 and

10270-511: The components of HVAC systems went hand-in-hand with the Industrial Revolution , and new methods of modernization, higher efficiency, and system control are constantly being introduced by companies and inventors worldwide. Heaters are appliances whose purpose is to generate heat (i.e. warmth) for the building. This can be done via central heating . Such a system contains a boiler , furnace , or heat pump to heat water, steam, or air in

10400-413: The condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor. HVAC is significantly responsible for promoting energy efficiency of buildings as the building sector consumes the largest percentage of global energy. Since the 1980s, manufacturers of HVAC equipment have been making an effort to make

10530-446: The control system will open (fully or partially) the outside air damper and close (fully or partially) the return air damper. This will cause fresh, outside air to be supplied to the system. When the outside air is cooler than the demanded cool air, this will allow the demand to be met without using the mechanical supply of cooling (typically chilled water or a direct expansion "DX" unit), thus saving energy. The control system can compare

10660-415: The cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season. Some systems include an "economizer mode", which is sometimes called a "free-cooling mode". When economizing,

10790-515: The direct control of the Ministry of Education therefore have direct funding from the ministry. Provincial Schools consists of the vast majority of schools in Sri Lanka which are funded and controlled by the local governments. Piriven are monastic college (similar to a seminary) for the education of Buddhist priests. These have been the centres of secondary and higher education in ancient times for lay people as well. Today these are funded and maintained by

10920-444: The education sector within the government. Although some, especially high schools, have started to charge a fair portion of parents of students an additional tuition fee, due to the increased places offered by the schools in recent years. Top state schools are often very selective, however. Students who miss their entrance requirement may still gain places if they meet a relatively lower requirement and their parents are willing to pay for

11050-414: The elementary district, which covers grades Pre-Kindergarten to 8, is 3013040. The NCES code for the high school district is 3013050. The elementary school district and high school district have the same territory, and include: Great Falls, Black Eagle , Gibson Flats , Malmstrom Air Force Base , and portions of Sun Prairie and Ulm . The city's public school system was established in 1886. That year,

11180-646: The emission of carbon monoxide , nitrogen oxides , formaldehyde , volatile organic compounds , and other combustion byproducts. Incomplete combustion occurs when there is insufficient oxygen; the inputs are fuels containing various contaminants and the outputs are harmful byproducts, most dangerously carbon monoxide, which is a tasteless and odorless gas with serious adverse health effects. Without proper ventilation, carbon monoxide can be lethal at concentrations of 1000 ppm (0.1%). However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in

11310-609: The equivalent. Schools are generally divided into elementary schools (kindergarten to Grade 8) and high schools (Grades 9 to 12). However, in many areas, middle schools are also provided and in some schools, particularly in rural areas, the elementary and middle levels can be combined into one school. In 2003, Grade 13, also known as the Ontario Academic Credit or "OAC" year, was eliminated in Ontario; it had previously been required only for students who intended to go on to university. Children are required to attend school until

11440-499: The examinations themselves. It is comparable to British A-Levels , American SATs , the Irish Leaving Certificate and German Abitur . Most students sit for the baccalauréat général which is divided into three streams of study, called séries . The série scientifique (S) is concerned with mathematics and natural sciences , the série économique et sociale (ES) with economics and social sciences , and

11570-410: The exception of kindergarten. All aspects of public education are the responsibility of the Ministry of Education, which executes administration of schools, allocation of funding, certification of teachers and schools, and curriculum development with standardised textbooks across the country. In 2000, South Korea spent 4.2% of its GDP in education. As of the 2007 United Nations Education Index, South Korea

11700-410: The existing Lowell Elementary School and constructing a new Roosevelt Elementary School on the site; $ 15.2 rebuilding Longfellow Elementary School; and $ 1 million on phone system upgrades throughout the district. Voters were asked to approve one bond levy for the high schools, and another bond levy for the elementary and middle schools. A "Yes for Great Falls Kids Ballot Initiative Committee" was formed by

11830-540: The federal government authority to regulate education. However, any public or private school that accepts educational funding from the federal government, including participation in collegiate federal financial aid programs such as Pell Grants and Stafford Loans by accepting the funds or participating in a particular federal program, is subject to federal jurisdiction as a result of that participation. The U.S. Department of Education , based in Washington, D.C. , supervises

11960-587: The first comfort air conditioning system, which was designed in 1902 by Alfred Wolff (Cooper, 2003) for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year. Coyne College was the first school to offer HVAC training in 1899. The first residential AC was installed by 1914, and by the 1950s there was "widespread adoption of residential AC". The invention of

12090-415: The first known national public schools called Ju-Hak ( Korean :  주학 ; Hanja :  州學 ) were opened in each Ju and Gun, states and counties, to improve nationwide academic performances. After the ceasefire agreement for the civil war was declared, north and south states of Korea established their own education system. In South Korea , education in public schools (1–12) is compulsory with

12220-479: The goal of developing first-class education in a limited number of schools in a short period of time. The key school system was canceled by the 2006 amendment to the Compulsory Education Law, along with the introduction of reforms that address education inequality. In Hong Kong the term government schools is used for free schools funded by the government. There are also subsidised schools, which are

12350-433: The greatest protection. Natural ventilation costs little and is maintenance free, and is particularly suited to limited-resource settings and tropical climates, where the burden of TB and institutional TB transmission is highest. In settings where respiratory isolation is difficult and climate permits, windows and doors should be opened to reduce the risk of airborne contagion. Natural ventilation requires little maintenance and

12480-417: The heated air through ductwork systems of supply and return air through metal or fiberglass ducts. Many systems use the same ducts to distribute air cooled by an evaporator coil for air conditioning. The air supply is normally filtered through air filters to remove dust and pollen particles. The use of furnaces, space heaters, and boilers as a method of indoor heating could result in incomplete combustion and

12610-692: The individual schools within their jurisdiction. In most states, the county or regional intermediate school districts merely implement state education policy and provide the channels through which a local district communicates with a state board of education, state superintendent, and department of education. They do not establish county or regional policies of their own. Local school districts are administered by local school boards , which operate public elementary and high schools within their boundaries. Public schools are often funded by local taxpayers, and most school boards are elected. However, some states have adopted new funding models that are not dependent upon

12740-568: The interior air. Methods for ventilating a building are divided into mechanical/forced and natural types. The three major functions of heating, ventilation, and air conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can be used in both domestic and commercial environments. HVAC systems can provide ventilation, and maintain pressure relationships between spaces. The means of air delivery and removal from spaces

12870-494: The internal air. Conversely, a humidifier increases the humidity of a building. The HVAC components that dehumidify the ventilation air deserve careful attention because outdoor air constitutes most of the annual humidity load for nearly all buildings. All modern air conditioning systems, even small window package units, are equipped with internal air filters. These are generally of a lightweight gauze-like material, and must be replaced or washed as conditions warrant. For example,

13000-568: The islands and mandated the establishment of a school for boys and a school for girls in every municipality. The modern public schools in the Philippines are run by the Department of Education . Some public schools collect miscellaneous school fees to fund school extra-curricular activities or to improve school equipment and services. Most of the schools in Sri Lanka are maintained by the government as

13130-496: The local economy. Public schools are provided mainly by local governments. Curricula, funding, teaching, and other policies are set through locally elected school boards by jurisdiction over school districts. The school districts are special-purpose districts authorised by provisions of state law. Generally, state governments set minimum standards relating to almost all activities of elementary and high schools, as well as funding and authorisation to enact local school taxes to support

13260-511: The majority in Hong Kong and many of which are run by religious organisations, Direct Subsidy Scheme schools, private schools and international schools in Hong Kong. Some schools are international schools, which are not subsidised by the government. During British rule, a number of state higher education establishments were set up (such as Universities in Chennai , Kolkata , and Mumbai ), but little

13390-519: The mandate for rural public schools to have a higher student-to-teacher ratio. The inequality of resources is exacerbated by the way public schools in urban areas enjoy more support since local governments have more developed economies. Aside from the disparity between urban and rural public schools, there was also the dichotomized system adopted since 1978, which divided schools into two groups: key schools ( zhongdianxiao ) and non-key schools ( putongxiao ). Key schools receive more funding due to

13520-599: The ministry of education bureaucracy. HVAC HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fresh air from outdoors. Ventilating or ventilation (the "V" in HVAC)

13650-400: The opening of this vent. Typical fresh air intake is about 10% of the total supply air. Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation , convection, or conduction . The heat transfer medium is a refrigeration system, such as water, air, ice, and chemicals are referred to as refrigerants . A refrigerant is employed either in

13780-569: The overall heating-portion of the DHC network (likely with energy added to boost the temperature). Basing HVAC on a larger network helps provide an economy of scale that is often not possible for individual buildings, for utilizing renewable energy sources such as solar heat, winter's cold, the cooling potential in some places of lakes or seawater for free cooling , and the enabling function of seasonal thermal energy storage . By utilizing natural sources that can be used for HVAC systems it can make

13910-513: The rest in the workplace to hone their skills. Grammar schools may be run by the local authority , a foundation body or an academy trust. They select their pupils based on academic ability. The original purpose of medieval grammar schools was the teaching of Latin. Over time the curriculum was broadened, first to include Ancient Greek , and later English and other European languages, natural sciences, mathematics, history, geography, art and other subjects. In some localities children can enter

14040-517: The right to observe deliberations and examine documents at public meetings). GFPS attorneys argued that state law provided an exception in the case of collective bargaining negotiations. A state district court ruled in favor of the school district, but a state appellate court overturned that ruling and held the state law's collective bargaining exception to be unconstitutional. In 1992 in Great Falls Tribune Co. v. Great Falls Public Schools ,

14170-587: The role of the federal government in education. Direct regulation of public, private, and parochial schools is done by state and territorial governments; schools in Washington, D.C., are regulated by the Government of the District of Columbia . Regulation of public schools is typically accomplished through a state education agency and a state department of education. There is usually a state superintendent of schools , who

14300-406: The rooms. Split systems are more efficient and the footprint is typically smaller than the package systems. On the other hand, package systems tend to have a slightly lower indoor noise level compared to split systems since the fan motor is located outside. Dehumidification (air drying) in an air conditioning system is provided by the evaporator. Since the evaporator operates at a temperature below

14430-423: The school district and parents to drum up support for the two bond issues. A voter-supported group, "Citizens for Better Schools", formed to oppose the bond issue. Voters approved the high school levy by 60.9 percent (11,341 to 7,187), and the elementary/middle school levy by 57.4 percent (10,680 to 7,919 votes). The Great Falls Public Schools is led by a seven-member board of trustees, which from among their members

14560-454: The school specialises, such as Cirencester Deer Park School which currently has 5 specialisms. State schools may request payment from parents for extracurricular activities such as swimming lessons and field trips, provided these charges are voluntary. Comprehensive schools typically describe secondary schools for pupils aged approximately 11–18, that do not select its intake on the basis of academic achievement or aptitude, in contrast to

14690-658: The schools, primarily through real property taxes. The federal government funds aid to states and school districts that meet minimum federal standards. School accreditation decisions are made by voluntary regional associations. The first free public school in America was the Syms-Eaton Academy (1634) in Hampton, Virginia , and the first tax-supported public school in America was in Dedham, Massachusetts , founded by Rev. Ralph Wheelock . In

14820-438: The split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity so that short lengths of duct handle air from the indoor unit to vents or diffusers around

14950-447: The system intended to maintain constant indoor air conditions. Outside, fresh air is generally drawn into the system by a vent into a mix air chamber for mixing with the space return air. Then the mixture air enters an indoor or outdoor heat exchanger section where the air is to be cooled down, then be guided to the space creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting

15080-533: The teacher, as police found no evidence that she directly abused the child. Montana's Attorney General Steve Bullock declined to investigate the allegations, arguing that this was the province of city prosecutors and he would not second-guess them without clear evidence of abuse of prosecutorial discretion . He also contended that the allegations were a matter of professional ethics and district school policy, and should be handled administratively. Great Falls city prosecutors eventually agreed to defer charges against

15210-581: The temperature of the outside air vs. return air, or it can compare the enthalpy of the air, as is frequently done in climates where humidity is more of an issue. In both cases, the outside air must be less energetic than the return air for the system to enter the economizer mode. Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in

15340-559: The term "Christian school" is generally used to refer to schools operated by Evangelical, Pentecostal, Charismatic, or fundamentalist Christian churches. The role of the U.S. federal government in education is limited and indirect. Direct control of education is a power reserved to the states under the Tenth Amendment to the United States Constitution because the U.S. Constitution does not explicitly or implicitly give

15470-792: The term public schools ( escuelas públicas in Spanish , escolas públicas in Portuguese ) is used for educational institutions owned by the federal, state, or city governments which do not charge tuition. Such schools exist in all levels of education, from the very beginning through post-secondary studies. Mexico has nine years of free and compulsory primary and secondary education. Panama has 11 years of compulsory education, from pre-kindergarten to 9th grade, with children first entering at four or five years old and parents are required by law to give financial support to their children until they are 25 years old if they are studying. Education in Argentina

15600-594: The two. In November 2011, several families of special needs children filed a lawsuit against the school district, alleging that GFPS knew the paraprofessionals were abusing children in February 2008 (a year before the Schilling case came to light). GFPS settled out of court with seven families in November 2012, agreeing to pay a total of $ 595,000 to parents of children abused between 2007 and 2009. Meanwhile, in 2010, Schilling filed

15730-521: The use of a built-in LED UV light that emits a gentle glow across the evaporator. As the cross-flow fan circulates the room air, any viruses are guided through the sterilization module’s irradiation range, rendering them instantly inactive. An air conditioning system, or a standalone air conditioner, provides cooling and/or humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against

15860-624: The world. Western education became ingrained into Indian society with the establishment of the British Raj. Education in Indonesia is overseen by two government ministries: the Ministry of Education and Culture for all education matters up to the tertiary education, and the Ministry of Religious Affairs for Islamic school matters up to the tertiary education. Education may be obtained from state schools, private schools , or through homeschooling . There

15990-462: Was also the first teacher in the GFPS school district to be appointed a Teacher on Special Assignment—in which a gifted teacher is removed from the classroom in order to develop good-teaching materials, and train and coach teachers into becoming better educators. Lacey's salary was $ 136,000 ($ 177,888 in 2023 dollars), and she was given a three-year contract. In January 2015, the GFPS school board extended Lacey's contract another three years. In May 2015,

16120-534: Was done by the British in terms of primary and secondary schooling. Other indigenous forms of education are being revived in various ways across India. According to current estimates, 80% of all Indian schools are government schools making the government the major provider of education. However, because of the poor quality of public education, 27% of Indian children are privately educated. According to some research, private schools often provide superior educational results at

16250-412: Was established in 2010 by the Great Falls Public Schools to act as the community recipient for donations made to the public school system. The foundation's goal is to establish a permanent fund that can support both the most disadvantaged and neediest students in the school system, as well as provide enhanced education, rewards, and opportunities for high-achieving students and educators. In November 2016,

16380-536: Was modelled after the public education systems of the Song and Tang Dynasties in China. Hak-Je involved operating national universities, called Gukjagam in the capital and called HyangAk in other regions. In King SeongJong Year 6, 987 A.D., a pair of a medical doctor and a scholarly doctor were appointed to administer academic systems and curriculums at Hyang-Ak: scholarly education included subjects of geography, history, math, law, and others. In King SeongJong Year 11, 992 A.D.,

16510-497: Was ranked eighth in the world. Education in Malaysia is overseen by two government ministries: the Ministry of Education for matters up to the secondary level, and the Ministry of Higher Education for tertiary education. Although education is the responsibility of the federal government, each state has an Education Department to help co-ordinate educational matters in their respective states. The main legislation governing education

16640-450: Was still not resolved. The Great Falls Public Schools spent $ 5,998 per pupil in the 2010–2011 school year, substantially less than the statewide average of $ 6,356 per pupil. As of the 2023–24 school year, the district operated the following public schools: Pre-School Elementary schools Middle schools High schools Former schools (and their current uses as of 2024), include: The Great Falls Public Schools Foundation (GFPSF)

16770-451: Was the city's first junior high school. The city's second high school, Charles M. Russell High School , was built in 1964 and opened in the fall of 1965. Skyline Elementary School opened in 1970, and as of 2015 was the last school building constructed in the school district. The school district weathered a deeply divisive 15-day teachers' strike in 1975 in which class size and pay were the primary issues. A 29-day strike occurred in 1989. In

16900-574: Was the largest given to any school district by the state. Tammy Lacey took over as school district superintendent on July 1, 2013. Lacey, who has a Master of Arts degree in educational leadership , is a graduate of Charles M. Russell High School. She was formerly a first grade teacher at Valley View Elementary School in Great Falls; principal at Fairfield Elementary School in Fairfield, Montana ; and Human Resources Director for GFPS from 2007 to 2013.
