Air Circulation - Whirlpool MULLION EVAPORATOR DESIGN User Manual

AIR CIRCULATION

The evaporator fan circulates air inside the refrig-
erator and freezer sections. ( Fig. 24) Most of the
air circulates inside the freezer compartment, and
returns to the evaporator from slots in the front and
rear of the freezer floor. The return air travels be-
tween the floor and the liner, where it joins other
return air at the back, flowing beneath the evapora-
tor cover and up through the evaporator coil.
Cold air is also sent to the refrigerator section
through the air duct at the rear of the freezer sec-
tion. The cold air enters the refrigerator section
through a diffuser. Part of the air is forced forward
where is passes through the front part of the com-
partment and the shelves in the door. Part of the
cold air is directed down the back of the compart-
ment to cool the lower portion of the refrigerator
section. The warmed air is then returned to the
freezer section through two air return ducts.
