(54) Cooling/heating apparatus


(57) The present invention provides a cooling/heating apparatus which allows improvement in heating efficiency in a first heat exchanger (36a,36b) provided in a housing to be heated. That is, among a plurality of housing, a third heat exchanger (42) is provided to exchange heat of a refrigerant flowing out of the first heat exchanger (36a,36b) provided in the housing heating goods with heat of the refrigerant sucked into by a compressor (41a,41b). Therefore, by increasing a temperature of the refrigerant sucked into by the compressor, a temperature of the refrigerant discharged from the compressor can be increased.
