ABSTRACT:
A housing for the low side evaporator coil of a refrigeration unit which housing is separately mounted on an exterior wall of a refrigerator compartment and which employs an energy saving air defrost system that, during a defrost cycle, draws ambient air into the housing from one end and discharges it from the other end after it flows past the frosted coil. The housing comprises a preformed unitary body section having opposite ends, a generally centrally located center chamber, a pair of generally cylindrically shaped valve chambers and associated dampers having conforming cylindrical wall sections generally located in the center of each end, and a pair of air passages extending at one end into each valve chamber and at the other end to the exterior. Easy access for servicing or the like is obtained, through a hinged door, to the refrigeration components which are slidably mounted within the center chamber of the body section.
