The 2 section refrigerator (1) is a glass front, two door unit employing a conventional air cooled
refrigeration system. In this system, refrigerant gas is taken into a compressor and discharged at high
pressure into an air cooled condenser. Heat is removed from the refrigerant in the condenser and
dissipated into the air. The refrigerant cools enough in the condenser to liquefy. Liquid refrigerant is
conducted to a metering device, which sprays liquid refrigerant into the evaporator. The evaporator
operates at much lower pressure than the condenser, and the refrigerant flashes off into gas, absorbing
heat in the process. The warm gas exiting the evaporator is then returned to the compressor to begin the
cycle again.
A thermostat monitors the cabinet temperature, and cycles the refrigeration system on and off as
required. The thermostat is adjustable, but does not normally require any adjustment.
The 2 section refrigerator may be equipped with an electric defrost system, incorporating a timer and an
electric heating grid attached to the evaporator. The timer can be set to operate the defrost grid at any
time desired. Models without an electric defrost system rely on the cabinet air to defrost the evaporator
when the refrigeration system has cycled off.
