Abstract

A heat pump comprising a circuit including: a first heat exchanger (1.3) operatively connected to a heat or coolth sink; a second heat exchanger (1.7) operatively connected to a heat or coolth source; a working fluid; pumping means (1.2); and an expansion device (1.6) connected between the heat exchangers; the circuit being arranged so that working fluid is circulated between the heat exchangers by the pumping means so that working fluid passes successively from the pumping means to the first heat exchanger, the expansion device, the second heat exchanger and returns to the pumping means; the first heat exchanger including a first conduit for a heat transfer fluid; the second heat exchanger including a second conduit for a heat transfer fluid; wherein the heat exchangers provide temperature glides to respective flows of heat transfer fluid with the temperature at one end of the first exchanger being approximately equal to the temperature of the heat transfer fluid leaving the heat or coolth source.
