Abstract

A heat pump suitable for domestic use is housed in a unit designed to reduce the noise from the pump, compressor and motor. The evaporator (4) has a thermostatically operated valve (18) at its discharge side to keep the temperature of the fluid evaporating inside to a constant level so as to keep the efficiency constant. The heat exchange fluid is a chlorofluoro hydrocarbon. Between the condenser (12) and the heat exchanger (4) forming the evaporator is a pressure reducer (16) which may be a nozzle. The compressor (8) is housed inside a cast metal casing (40) with wells 5 to 10 mm thick. This casing, the evaporator (4), the pressure reducer (16) and the valve (18), are housed inside a further enclosure (48) lined with felt (52), with the condenser (12) above it, housed under the outer casing (54).
