	Air conditioner - Wikipedia, the free encyclopedia
		Air conditioner equipment cooling capacity in the U.S. is often described in terms of "tons of refrigeration".
		Residential air conditioning is ubiquitous in Japan, South Korea, Taiwan, Singapore and Hong Kong, especially in the latter two due to most of the population living in small high-rise flats in warm climates.
		Still, the lack of air conditioning in homes, in residential care homes, and in medical facilities was identified as a contributing factor to the estimated 35,000 deaths left in the wake of the 2003 heat wave.

	Central Missouri - Air Conditioning
		The heat removed from the air and transferred to the refrigerant is then rejected to a cooling fluid stream (typically water in southern climates).
		Central air conditioners are rated according to their seasonal energy efficiency ratio, or SEER.
		Air conditioners are sized according to Btus of heat removed per hour, or in "tons" of refrigeration, with one ton equaling 12,000 Btus per hour.

		The new device (5-8 kw) can't heat infiltrated (leaking into the home) air that is entering from all the various places established for combustion air supply to the replaced (10-15 kw) multi-fuelled heater.
		Air transported moisture occurs when air leaks from the warm side of the wall to the cool side.
		Moisture carried by air flow through the wall is deposited at the back of the exterior and accumulates in the Insulation and its bay.

	EERE Consumer's Guide: Central Air Conditioners
		Air conditioners help to dehumidify the incoming air, but in extremely humid climates or in cases where the air conditioner is oversized, it may not achieve a low humidity.
		In a packaged central air conditioner, the evaporator, condenser, and compressor are all located in one cabinet, which usually is placed on a roof or on a concrete slab next to the house's foundation.
		Air supply and return ducts come from indoors through the home's exterior wall or roof to connect with the packaged air conditioner, which is usually located outdoors.

	Central Heat & Air
		In fact, a room air conditioner that's too big for the area it is supposed to cool will perform less efficiently and less effectively than a smaller, properly sized unit.
		If you have a central air system in your home, set the fan to shut off at the same time as the cooling unit (compressor).
		Evaporative coolers provide mechanical cooling to a building by either direct contact of air with water (direct evaporative cooler) or a combination of a first-stage heat exchanger to pre-cool the air and a second stage with direct air contact with water (indirect/direct evaporative cooler).

	Air Conditioning
		Air from the outdoor fan blows across these fins and it loses some of its heat.
		This gas then absorbs heat from the air traveling across the coil which is pulled in through the return air and into a sealed duct system by the indoor fan.
		As the warm air passes over the coil and is cooled it can't hold the same amount of moisture.

	Central Air Conditioners (Site not responding. Last check: 2007-10-09)
		Central air conditioners are split systems: an outdoor unit (the condensing unit) and an indoor unit (air handler).
		The function of an air conditioner is to transport heat from one station to another.
		Air conditioners cool your home by removing heat from the indoor air and transferring that heat to the outdoor air.

	Central Air Conditioning
		Central air conditioning, in which entire residences and other buildings are cooled and dehumidified, is popular in areas that are hot and humid year-round, but is also gaining popularity in other locations.
		A central air conditioning system is designed to cool indoor living spaces during hot weather, and to improve indoor air quality by filtering and dehumidifying the air.
		Central air conditioning is generally quieter than individual room air conditioners which radiate their compressor noise closer to the living areas.

		Residential central air conditioning systems that need to cool and dehumidify uses a condenser, evaporator coil, and refrigerant piping to operate.
		The means of moving the air might differ (furnace, air handler, etc.), but the principal is the same for all split systems.
		As the air passes over the evaporator coil and cools, moisture in the air condenses and drains off as condensate.

		Once the system has been properly charged with refrigerant and has good airflow across the indoor coil, and assuming there is no damage to the duct system, only basic service such as changing filters and cleaning the outdoor unit annually should be needed to maintain the system operation at peak performance levels.
		The ducts that are part of central heating and cooling systems offer one of the best opportunities to increase your energy efficiency, increase your comfort, and manage your energy bills.
		Studies indicate that 10%-30% of the heated or cooled air is lost-along with the money spent to heat or cool that air-through leaky ducts.
