A heat transfer device 1 for space cooling of the type in which a vaporisable refrigerant is circulated in a closed circuit including an evaporator 3 for collecting heat from air passed over the evaporator thus vaporising the refrigerant, a compressor 4 to compress the vaporised refrigerant and a condenser 5 to dissipate the heat collected to condense the refrigerant. The closed refrigerant circuit is housed in a casing 2 which is positioned in a cold space the air temperature of which is to be controlled and the heat generated during operation of the device 1 is prevented from returning to the cold space by surrounding the condenser 5 with thermally insulating material and positioning the compressor 4 in the air flow path to the evaporator 3. The condenser 5 forms part of a heat exchanger 18 connected to supply and return lines for circulation of a cooling fluid, e.g. water, to which the heat dissipated by the condenser is transferred. The device 1 may form part of a combined space cooling/water heating system in which the heat dissipated by the condenser is utilised to heat the water in a hot water supply. <IMAGE> |
