NORMAL OPERATING SOUNDS
All models incorporate rigid foam insulated cabinets to
provide high thermal effi
ciency and maximum sound
reduction for its internal working components. Despite this
technology, your model may make sounds that are
unfamiliar.
Normal operating sounds may be more noticeable because
of the unit’s environment. Hard
surfaces such as cabinets,
wood, vinyl or tiled floors
and paneled walls have a
tendency to reflect normal appliance operating noises.
Listed below are common re
frigeration components with
brief description of the normal operating sounds they
make. NOTE: Your product may not contain all the
components listed.
• Compressor: The compressor makes a hum or pulsin
g
sound that may be heard when it operates.
•
Evaporator: Refrigerant flowing through an evaporat
or

SAFETY • INSTALLATION & INTEGRATION • OPERATING INSTRUCTIONS • MAINTENANCE • SERVICE
THEORY OF OPERATION
Cooling process
Refrigerant is pumped from the compressor to the
condenser as a high pressure, high temperature vapor.
As the refrigerant cools in the high pressure condenser,
the vapor condenses to liquid. During this phase change,
a great amount of heat is rejected with the help of the
condenser fan.
The liquid then flows to the dryer where it is strained and
filtered.
From the dryer, the refrigerant flows through the capillary
tube which meters the liquid refrigerant to the evaporator.
The pressure of the refrigerant is reduced to the
evaporating or low side pressure.
The reduction of pressure on the liquid refrigerant causes
it to boil or vaporize until it reaches saturation
temperature. As the low temperature refrigerant passes
through the evaporator coil, it continues to absorb a lot of
heat, causing the boiling action to continue until the
refrigerant is completely vaporized. It is during this phase
that the most heat is absorbed (the cooling takes place) in
the refrigerator.
The refrigerant vapor leaving the evaporator travels
through the suction line to the compressor inlet. The
compressor takes the low pressure vapor and compresses
it, increasing both pressure and temperature. The hot,
high pressure gas is pumped out the discharge line and
into the condenser. The cycle continues.
