ABSTRACT:
A thermoelectric heat pump attached to a plate evaporator within the freezer compartment. The surface area of the thermoelectric device is maintained at a temperature substantially lower than the temperature of the evaporator plate during the cooling cycle. Accordingly, the majority of frost is collected on the thermoelectric surface area. Defrost is accomplished by reversing the voltage potential across the thermoelectric device and draining the water away in a suitable manner.
