Air Circulation - Electrolux 4-Door Refrigerator with R600a Service Manual

3. Air circulation

Freezer compartment: the cold produced by the battery evaporator is circulated by a fan positioned above the
evaporator. The air enters the right-hand compartment and flows back into the left-hand compartment through
special apertures. The temperature is controlled by the bulb of the open-air thermostat positioned immediately
above the battery.
Zero-degrees compartment: the air enters through a duct (embedded in polystyrene) positioned above the fan,
and exits through the apertures in the flap-operated thermostat. An aperture in the lower left-hand section of the
zero-degrees compartment allows the air to flow back into the freezer compartment. The temperature is
controlled by the flap-operated thermostat.
Refrigerator compartment: The air circulates by natural convection. The temperature is controlled by the bulb
of the hidden thermostat.
