ABSTRACT:
A microwave heat pump defroster system, utilizing a magnetron tube, or other microwave energy generating device, for the application of heat to the external surfaces of the outside coil of an electric heat pump, while the heat pump is operating in the heating mode for the following purposes, (1) to defrost the outside coil of the heat pump, (2) to inhibit the accumulation of frost on the external surfaces of the outside coil of the heat pump, and (3) to allow heat so applied to the external surfaces of the outside coil of the heat pump to be absorbed into the heat pump system via the outside coil of the heat pump, in a manner that will improve the efficiency of the heat pump.
