Cold producing process

Image Number 2 for United States Patent #4037426.

Process for producing cold by evaporation of a cooling fluid, comprising the steps of compressing a gaseous phase of the cooling fluid and dissolving it, at least partly, in a liquid solvent, precooling the resulting solution by an external fluid and further cooling it by heat exchange with a heavy and a light liquid phase, said heavy liquid phase being then recycled as liquid solvent for the gaseous phase of the cooling fluid, said light liquid phase being vaporized to produce cold, thereafter used for cooling said solution and recycled as gaseous phase of the cooling fluid.
