<p>The present invention, which relates to a method and equipment for transferring heat between fluids, involves combination of a multi-stage compressor with a series of heat-exchangers. The vapor of a condensable fluid is transmitted from one exchanger to the next by passing same through a compressor stage, the condensate returning by direct passage with flash effect. A fluid to be cooled gives up its heat within the exchangers to the condensable fluid which is progressively vaporized. The equipment may be completed by a symmetrical part in which the condensable fluid gives up its heat of condensation to a third fluid. The invention is applicable to the use of low-level temperature heats, e.g., of geothermal origin.</p> |
