Ventilation and Air-Conditioning
Heating, ventilation, and air conditioning HVAC  is the technology of indoor and vehicular environmental comfort. 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. 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 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 the interior air. Ventilation includes both the exchange of air to the outside as well as circulation of air within the building. It is one of the most important factors for maintaining acceptable indoor air quality in buildings.
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 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 the HVAC systems.
Specialty mechanical contractors then fabricate and commission the systems. Building permits and code-compliance inspections of the installations are normally required for all sizes of building. 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 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, [ citation needed ] the cooling potential in some places of lakes or seawater for free cooling , and the enabling function of seasonal thermal energy storage.
Multiple inventions within this time frame preceded the beginnings of first comfort air conditioning system, which was designed in by Alfred Wolff Cooper, for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year.
The invention of 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. This can be done via central heating. Such a system contains a boiler , furnace , or heat pump to heat water, steam, or air in 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. 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 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 s in Japan and the United States. Heat pumps transfer heat from outside the structure into 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.
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 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 heated air through duct work 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 cleaners 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 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 ppm 0. However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting.
Carbon monoxide binds with hemoglobin in 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 is the process of changing or replacing air in any space to control temperature or remove any combination of moisture, odors, smoke, heat, dust, airborne bacteria, or carbon dioxide, and to replenish oxygen.
Ventilation includes both the exchange of air with the outside as well as circulation of air within the building.
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 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.
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 the architecture permits. 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 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 a wind tunnel which have 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 is a key factor in reducing the spread of airborne illnesses such as tuberculosis, the common cold, influenza and meningitis. Opening doors, windows, and using ceiling fans are all ways to maximize natural ventilation and reduce the risk of airborne contagion.
Natural ventilation requires little maintenance and is inexpensive. An air conditioning system, or a standalone air conditioner, provides cooling and humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions.
Outside, fresh air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Air conditioning and refrigeration are provided through the removal of heat.
Heat can be removed through radiation , convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants. A refrigerant is employed either in a heat pump system in which a compressor is used to drive thermodynamic refrigeration cycle , or in a free cooling system which 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 system will lead to power wastage and inefficient usage. Adequate horsepower is required for any air conditioner installed. 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 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 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, 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.
Types of Cooling Systems
HVAC stands for Heating, Ventilating, and Air Conditioning, and HVAC systems are, effectively, everything from your air conditioner at home to the large systems used in industrial complexes and apartment blocks. A good HVAC system aims to provide thermal control and indoor comfort, and one that is designed using the principles of thermodynamics, fluid mechanics, and heat transfer. The big air conditioner boxes that you might see on top of apartment blocks or offices are examples of the visible part of HVAC systems. But heating and cooling systems you use in your home are also HVAC systems.
Smaller Chillers and Heat Rejection Equipment: By designing the system around hour per day chiller operation, the size of the chillers and cooling towers or air-cooled condensers required for an ice system is significantly reduced, when compared to conventional chillers and heat rejection equipment sized for the instantaneous peak load. A typical thermal storage design includes chillers that provide 50 to 60 percent of the peak cooling load. The balance of the cooling requirement is provided from the ice storage system. Reduced Pump and Pipe Sizes: Pump and pipe sizes are also reduced in a properly designed ice storage system.

Air conditioning, or cooling, is more complicated than heating. Instead of using energy to create heat, air conditioners use energy to take heat away. The most common air conditioning system uses a compressor cycle similar to the one used by your refrigerator to transfer heat from your house to the outdoors. Picture your house as a refrigerator. There is a compressor on the outside filled with a special fluid called a refrigerant.
Он застонал. Проклятые испанцы начинают службу с причастия. ГЛАВА 92 Сьюзан начала спускаться по лестнице в подсобное помещение.
Он глубоко вздохнул. - Сегодня утром Энсея Танкадо нашли мертвым в городе Севилья, в Испании. ГЛАВА 8 Двухмоторный Лирджет-60 коснулся раскаленной посадочной полосы.
Но Дэвид знал, что никогда ей этого не откроет. Секрет выражения без воска был ему слишком дорог.
Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы. - Танкадо обманул всех. По его тону ей стало ясно, что он все понял. Вся ложь Танкадо о невскрываемом алгоритме… обещание выставить его на аукцион - все это было игрой, мистификацией.
Сомнений не. В ярком свете уличного фонаря на углу Беккер увидел. Молодые люди поднялись по ступенькам, и двигатель автобуса снова взревел. Беккер вдруг понял, что непроизвольно рванулся вперед, перед его глазами маячил только один образ - черная помада на губах, жуткие тени под глазами и эти волосы… заплетенные в три торчащие в разные стороны косички.
Красную, белую и синюю. Автобус тронулся, а Беккер бежал за ним в черном облаке окиси углерода. - Espera! - крикнул он ему вдогонку.
Он сказал, что в прошлом году сам установил переключатель. Личный помощник директора отказывался верить ее словам. - Никогда не слышал об. - Никто не слышал.
