CS55 HOW IT WORKS:
REFRIGERATION
HARVEST CYCLE
(When the cubes are released)
The ice cubes have been formed in an
inverted mold that was refrigerated.
Now the refrigeration system will change to
warm the cube mold and release the cubes.
The process begins at the compressor.
There, refrigerant vapor is compressed and
flows from the compressor through the
discharge line as a high temperature, high
pressure gas. Before the gas gets to the
condenser,it goes through a strainer, the
strainer outlet is connected to two tubes,
one of which leads to an electric valve, the
hot gas solenoid. When this valve opens,
the refrigerant gas follows the path of least
resistance and flows through the tubing
from the hot gas valve to the evaporator,
where the ice cubes are frozen.
At the evaporator, the high temperature
gases are cooled by the cold temperatures
of the cube mold, and condense into liquid,
transferring heat to the mold which warms
up and releases the cubes.
The refrigerant, now a low pressure, low
temperature vapor, flows into the
accumulator, which traps excess liquid
refrigerant. The vapor, now primarily a gas,
goes through the suction line tube to the
compressor where the cycle is repeated.
