(54) | Heat-save cooler |
(57) 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). |
