Abstract

A single- or reversible-cycle heat-save cooler (1) having a first heat exchanger (2) where a cooling fluid exchanges heat with the outside environment; a second heat exchanger (3) where the cooling fluid exchanges heat with a first liquid; a cooling fluid compressor unit (5) where the cooling fluid is compressed to increase its pressure; and a third heat exchanger (4) where the cooling fluid exchanges heat with a second liquid; the third heat exchanger (4) being located immediately downstream from the compressor unit (5); and the cooler (1) also having a liquid-gas separating unit (17) located immediately downstream from the third heat exchanger (4) to retain all or part of the liquid cooling fluid issuing from the third heat exchanger (4). <IMAGE>
