ABSTRACT:
Apparatus and method for improving the efficiency of a heat pump for transferring heat and cold between two separate fluid streams, in which, during heating operation, the cooling medium is heated before decompression by the Joule's heat released upon compression. According to a preferred embodiment, prior to this heating by Joule's heat, the cooling medium is cooled by heat exchange with the fluid stream used for evaporation, which fluid stream is simultaneously heated.
