ABSTRACT:
In an apparatus for defrosting an evaporator in a heat pump which is driven by a compressor, the evaporator consists of a fan and a heat exchanger through which the fan drives air for heat exchange with the heat transport medium flowing through the heat exchanger. A pressure sensitive switch is arranged to actuate a member for reversal of the pumping direction of the compressor when the pressure differential .sigma. p of the air over the heat exchanger has reached a predetermined value, and a temperature sensitive switch which senses the temperature at the heat exchanger, is arranged to actuate the reversal member to maintain the reversed pumping direction of the compressor as long as the temperature at the heat exchanger is less than or equal to 0.degree. C.
