CS55 HOW IT WORKS:
REFRIGERATION
FREEZE CYCLE
The ice cubes are formed in an inverted
mold that is refrigerated.
The refrigeration 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. In
the discharge line there is a strainer with
two outlets, one leads to the condenser,
and one to a solenoid valve. Because the
solenoid valve is closed, the gas flows to
the condenser, where heat is transferred
from the refrigerant to the air passing
through the condenser. The refrigerant then
condenses into a high pressure liquid.
From the condenser, the liquid refrigerant
flows through the liquid line, and the liquid
line filter-drier. After the filter drier, the
liquid refrigerant enters the metering
device, a capillary tube. After passing the
restriction of the capillary tube, the
refrigerant enters an area of relative low
pressure, the evaporator. In the tubing of
the evaporator, the liquid refrigerant
expands and evaporates, absorbing heat
from the evaporator tubing and anything in
contact with it such as water sprayed
against it.
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.
