1) This heat is then carried by the refrigerant from the evaporator as a low-pressure gas through a hose or line to the low side of the compressor.

2) The evaporator removes heat from the area that is to be cooled.

3) The purpose of the compressor is to circulate the refrigerant in the system under pressure.

4) Two service valves are located near the compressor as an aid in servicing the system.
