In a gas-compression air-conditioning system, what is transferred from one place to another?

In a gas-compression air-conditioning system, the primary function is to transfer heat from one location to another, thereby cooling the indoor environment. The system works by removing heat from the inside of a building and expelling it outside, utilizing refrigerants that circulate through evaporator and condenser coils.

During this process, the refrigerant absorbs heat from the interior air as it evaporates and then releases that heat outdoors when it condenses back into a liquid. This mechanism effectively lowers the air temperature inside the building, rendering it comfortable for occupants. While humidity, cold air, and ventilation play roles in the overall indoor climate, the fundamental operation of air conditioning revolves around the movement of heat.
