REFRIGERATION CYCLE.

a. The Refrigeration Cycle. The refrigeration system removes heat from a given area.

(1) The compressor (1) takes cold, low pressure refrigerant gas and compresses it

to a high temperature, high pressure gas. This gas flows through the copper

tubing and metal hose assy (2) to the condenser coil (3A) and receiver (4).

(2) The condenser fan draws outside ambient air over and through the condenser

coil (3A). The high temperature, high pressure gas from the compressor (1) is

cooled by the flow of air and is changed into a high pressure liquid.

(3) The sight indicator (5) indicates the presence of moisture and quantity of

refrigerant in the system.
