1989 REFRIGERATORS
OPERATION OF UNIT
The
refrigeration
unit
contains
the complete sealed
refrigeration
system,
the
evaporator fan,
the
condenser
fan
and
the
defrost
system.
Air flow System
The condenser
fan
draws
in room
air
through
the
grille
in
the
front.
Warm
ai r,
from
the
condenser
and
compressor,
is
expelled through
the
right
side
and the front of the grille.
The evaporator fan
supplies
cold
air
down to the freezer and fresh
food
compartments
through
ducts
located
in
the
respective
compartments.
Cold air is distributed
into
the
freezer
compartment
through
louvers
in
the
front
of
the
freezer
compartment
above
the
freezer control.
The
temperature
control
capillary
is
located in
the
freezer
supply
air path.
Accordingly,
the
compressor
run
time is regulated by
the
freezer
supply
air temperature.
Warm air
is
returned
to
the
evaporator
through
a duct at the bottom rear
and partition in the back
of
the
freezer compartment.
In
the
fresh
food
compartment
freezer air is also directed
over
to
the fresh food compartment via
a channel in the front.
Cold
air
passes through the thermostatically
controlled
air
damper
and
is
directed back to the rear
of
the
compartment and
out
through this
same channel and down into the com-
partment.
Warm
air
is
returned
to the evaporator through a passage
between the fresh food and freezer
liner wall. The air is directed to
evaporator via
6
fresh
food
air
returns
located in the lower left
liner wall.
As
the
air is being
returned
to
the
evaporator
it
passes over the fresh food control
capillary end
which
is placed in
the
air
path
via
a
hole and
grommet through the liner wall.The
damper
senses temperature changes
and supplies cold air on demand.
