Some experimentation may be necessary before the location of
the partition is finalized.
A minimum of 4” of rigid polyurethane
foam insulation is mandatory on all box surfaces for this
application. Please do not attempt it with less. In boxes up to 8
or 9 cubic feet, it is generally possible to obtain 2-3 cubic feet of
below-freezing space by creating a suitable partition.
For the partition, use a sheet of 2” rigid polyurethane foam core
with fiberglass or Formica faces, tightly fitted and sealed airtight
to the box sides and bottom. The necessary materials should be
available locally (home improvement outlets) and are relatively
easy to work with.
For cool air feed to the refrigerator side, drill a 3” diameter hole
halfway up the partition and leave about a 1” gap at the top. This
will allow for natural convection airflow from the freezer to the
refrigerator section.
You may need to install a manual damper over the hole to better
control individual compartment temperatures. This can be a
simple disc with a single pivot screw. As an alternative, you can
use the Adler/Barbour self-powered, thermostatically controlled
Automatic Shutter (Part #D7230). Use one automatic shutter for
each four cubic feet of refrigerator space. For the shutter, cut a
slot 1-1/8” high x 4” wide instead of a 3” hole.
For side door refrigerators, a Spillover Fan Kit #C7210 is
preferred—please see the following section.
