Air conditioners come in all sorts of sizes and shapes, but they essentially all work on the same underlying principle. An air conditioner removes humidity and heat from your indoor air by effectively removing these elements from the air. The compressor heats up the refrigerant gas (often referred to as Freon) and transfers it to the condensing coil on the compressor shaft, where it is converted into a cool liquid to be cooled further. This process continually takes place until the desired temperature has been reached by the air being replaced by cooler outside air.
The major advantage of air conditioners is that by using a fan or blower they can provide a constant flow of warm air inside the home, removing heat created by the sun and heating created by heating equipment such as heaters. Some air conditioners are also capable of cooling water, though this is not commonly found in many homes as the water will usually already be very cold before it needs to be cooled. This is known as an air-to-water heat exchanger, which is a rather crude but practical type of system. Other types of air conditioner employ the use of a liquid such as Freon to absorb heat, rather than just air.
Air conditioning systems also differ depending on whether you are dealing with a single room, a house or an entire building. Single room air conditioners can be installed in any room of your home – they are not, however, as cheap as room air conditioning units. House air conditioning is generally more expensive than single room units because of the additional insulation required to regulate the temperature and the fact that many existing ductwork and heating ducts may need to be upgraded to accommodate the unit. Air conditioning is especially important during the winter months when the temperature outdoors is significantly colder than the temperature inside. This is due to the fact that outside air often contains high levels of moisture and, as a result, dehumidifies the home. Air conditioners in houses reduce the amount of moisture that is absorbed by the walls and ceilings, thus making room’s much cooler.
