At its most fundamental a refrigeration cycle makes up four important components to provide air conditioning: A refrigerant. This will start the cycle in a gaseous state. A will certainly then pump the refrigerant gas up to a high pressure and temperature level. During the next phase of the process the gas enters a form of warm exchanger, usually referred to as the or condenser.


As it cools it will certainly condense right into its fluid state. Some kind of or vein will certainly regulate the cooling agent fluid flow to guarantee the proper price.
