ABSTRACT:
A refrigerating device has a housing including at least one storage compartment. A cooling apparatus including an evaporator, a compressor and a condenser is accommodated in the base of the housing, the evaporator being surrounded by a casing of a thermally conductive material in good thermal contact with the evaporator. The casing separates a passage for circulating a stream of air to be cooled from an additional passage through which an additional stream of air is intermittently passed, after being conducted past or through the condenser or compressor of the cooling apparatus and being heated thereby, the heated additional stream of air defrosting the evaporator. The intermittent passage of the stream of hot air is controlled by deviating flap valves which may be insulated, the position of the flap valves being controlled in dependence on operating parameters of the cooling apparatus.
