Cold Air Flow Schematic Diagram - Electrolux DF36 Service Manual

5. COLD AIR FLOW SCHEMATIC DIAGRAM

The cold air generated in the evaporator is forced into the freezer
compartment and into the refrigerator compartment by the
motofan.
In the freezer compartment the cold air is distributed through
the top flow to the shelves and the food is frozen by the cold
air flow.
In the refrigerator compartment, the cold air flow coming from
the evaporator is carried by the freezer's top flow passing
through the manual damper that will control the amount (flow
rate) of cold air that will be redirected to cool down the
refrigerator compartment.
The manual damper has three positions:
· Maximum Refrigerator: 80% of the air flow rate is
redirected to the refrigerator implying in a faster cooling
rate in the refrigerator compartment.
· Normal: 50% of the air flow rate is redirected to the
refrigerator.
· Maximum Freezer: only 20% of the air flow rate is
redirected to the refrigerator thus implying in a slower cooling
rate in the refrigerator compartment.
After passing through the manual damper, the cold air flow
will be carried through a space in the intermediary division
between the freezer and the refrigerator compartments to the
top flow duct of the refrigerator that will then uniformly distribute
it through that compartment.
After cooling down the refrigerator compartment the air will
return through the refrigerator's Top Flow back, which will direct
it through another space in the intermediary division between
the freezer and refrigerator compartments, to the freezer's
evaporator.
