1.9.1 The Refrigeration Cycle. The refrigeration system removes heat from a given area.
a. 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 assembly (2) to the condenser coil (3A) and receiver
(4).
b. The condenser fan draws outside ambient air over and through the condenser coil (3A). The high temperate,
high pressure gas from the compressor (1) is cooled by the flow of air and is changed into a high pressure liquid.
c. The sight indicator (5) indicates the presence of moisture and quantity of refrigerant in the system.
d. The dehydrator (6) removes any moisture (water vapor) or dirt that maybe carried by the liquid refrigerant.
e. The solenoid valve (7) is controlled by the temperature selector on the control panel. This valve will shutoff the
flow of refrigerant to the evaporator section when the temperature in the conditioned area reaches the set point.
