Section Ill TECHNICAL PRINCIPLES OF OPERATION
The following information describes the function of the components in this unit, listed in the order that the
refrigerant flows through the refrigeration system. (See figure 1-3.)
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 METAL HOSE ASSEMBLY (DISCHARGE) (2) and
metal tubing to the CONDENSER COIL (3), RECEIVER (4), and SUBCOOLER (5).
b. The CONDENSER FAN (6) draws outside ambient air through the CONDENSER COIL (3) and
SUBCOOLER (5). The high temperature, high pressure gas from the COMPRESSOR (1) is cooled by the flow of
air and condenses to a high pressure liquid.
c. The SIGHT GLASS (7) indicates the presence of moisture and quantity of refrigerant in the system.
d. The REFRIGERANT DESICCANT DEHYDRATOR (filter-drier) (8) removes any moisture (water vapor)
or dirt that may be carried by the Iiquid refrigerant.
