A vapor compression refrigeration system (VCRS) is a closed system that uses a refrigerant to cool the surrounding air. VCRS systems are used in many commercial and domestic refrigeration and air conditioning plants. 

Here's how a VCRS works:
The refrigerant is compressed and expanded through four stages, changing its state from a liquid to a vapor.
As the refrigerant changes state, heat is absorbed and expelled by the system, lowering the temperature of the conditioned space.
The working fluid absorbs heat in an amount equivalent to its refrigerating effect.
The extracted heat is rejected to some form of sink, usually atmospheric air or surface water. 

VCRS systems are made up of four main components:
Evaporator: A series of coils that create surface area for the refrigerant to react with
Condenser: A series of coils that allow airflow to the exterior 

Refrigerants usually used are ammonia (NH3), carbon dioxide (CO2), and sulfur dioxide.
