REFRIGERATION SYSTEM
FUNCTIONALITY
These cases can be used for frozen food. These
merchandiser model is self-contained and has
a controller that automates the refrigeration
cycle and the defrost cycle.
During refrigeration mode, the discharge line
solenoid valve (RSV) is energized and held
open, allowing the gas to flow through the
condenser.
Once the refrigerant is in a liquid state, a
capillary tube is used as an expansion device
that feeds the evaporator.
During refrigeration mode, hot gas solenoid
valve (HGSV) is deenergized and closed.
