AIRFLOW
AIR FLOW
Airflow
Freezer Compartment
Cold air from the evaporator is forced up against
the top of the freezer and the back of the
evaporator cover. It is then discharged through
slots along the air tower at the rear of the
freezer compartment.
Air is circulated by the evaporator fan
throughout the freezer compartment, where it
picks up heat and moisture. The evaporator fan
then draws the warmer, moisture-laden air
through return louvers in the bottom of the
evaporator cover. The air is then drawn through
the evaporator where heat is removed and
moisture is deposited as frost.
COLD AIR MIXED AIR WARMER AIR
Fresh Food Compartment
Some of the cold air that is being forced against
the top of the freezer and back of the evaporator
cover is diverted through the lower portion of the
freezer air tower and is pushed though the
mullion hole into the fresh food compartment air
channel. The air then exits the air channel in the
front of the fresh food compartment, creating a
curtain of cold air along the front of the shelves.
The fresh food air channel also has a rear
discharge to maintain deli drawer temperatures.
Air circulates throughout the fresh food
compartment, picking up heat and moisture.
The air is then returned to the evaporator
through the return air ducts located at the top
GEA01143
right and left of the fresh food compartment.
Note: These refrigerators do NOT use damper
assemblies to regulate the flow of air to the
fresh food compartment. Airflow is regulated by
a three-speed evaporator fan and a sized air
duct system that provide predictable, consistent
air exchange rates for each level of fan speed.
