Refrigerator Service ManualN6XX/N8XX Models
An additional challenge with double sidewall venting is
the depth of the enclosure. The deeper the enclosure,
the greater the impact on the air flow through the rear
of the refrigerator. Taking the three key design
considerations and the variable depth requirement into
account, NORCOLD developed and tested several
baffle arrangements for the N6XX and N8XX models
versus their ability to meet the ANSI standards.
As the result of this testing, NORCOLD was able to
reduce the baffle configuration down to two baffles for
the N6XX and N8XX models. It should be noted that
baffle arrangements are different if the enclosure depth
is greater or less than 26 inches. The baffle
configurations are shown in Figure 6, page 25, and
Figure 7, page 26.
Air Intake Vent
The ventilation and combustion air flow into the
enclosure through the air intake vent. See Figure 6,
page 25 and Figure 7, page 26.
Sidewall Exhaust Vent
The heat absorbed by ventilation air and combustion
gases flow out of the enclosure through the sidewall
exhaust vent. See Figure 6, page 25, and Figure 7,
page 26 for details.
Double Sidewall Venting
With increased installation of refrigerators in RV slide
outs. NORCOLD has conducted extensive testing to
develop venting guidelines for double sidewall vent
applications. This work was done to ensure NORCOLD
refrigerators meet the ANSI Z21.19 standards for
cooling performance when used in slide out
applications.
The challenge with slide out installations is that the
"chimney effect" that is present with roof vent
installations is not as strong in slide outs. To improve
the "chimney effect" side vent installations must have
fans and baffles. These fans and baffles direct the air
flow through the surfaces of heat rejecting
components. NORCOLD has determined that the
following three key design considerations optimize
heat removal in slide out applications.
n Refrigerators installed in slide outs must have a fan
or fans to assist air flow. Fan kits and refrigerators
with factory installed fan(s) are available from
NORCOLD.
n Fresh air must be directed to flow through the
surface areas of the absorber coils, condenser fins,
and the outer surface of the canister.
n Corners and structural pockets where heated air
may stagnate must be reduced in size or
completely eliminated.
The general guidelines for intake vents and roof exhaust
vents presented in this section do not replace the
instructions and/or guidelines provided in the N6XX/
N8XX model refrigerator installation manual and the
Ventilation Guidelines For Gas/Electric Refrigerators
part number 622090A (3-01). Refer to the N6XX/N8XX
installation manual and Ventilation Guidelines For Gas/
Electric Refrigerators for the latest information on
approved vents, installation instructions, and special
construction exceptions.
