Throughout the following stage of the procedure the gas enters a form of heat exchanger, typically called the or condenser.


As it cools it will certainly condense into its fluid state. Some sort of or capillary will manage the cooling agent liquid flow to make certain the proper rate. Finally, the fluid cooling agent is returned to another warmth exchanger where to vaporize, thus the heat exchanger on this side of the system is often called the or evaporator.

Equipments with little storages can be hybrid, making use of cost-free cooling at the beginning of the warmer season prior to changing to a warm pump to further cool the blood circulation coming from the storage later on in the season. These heat pumps are added-in because the storage space works as a warm sink when the system is in air conditioning (in contrast to billing) mode, causing the temperature level to slowly increase throughout the air conditioning period.


return air or contrast the enthalpy of the air, which is commonly performed in high humidity environments and it creates more of an issue. In both instances, the outside air has to be less energised than the return air for the system to go into the economiser setting.
