Abstract
A heat pump system and method utilizes heat of mixing, in addition to the latent heat of solution, to increase cooling ability and thermal performance. The system includes a unique two-phase compressor for compressing a two-component mixture of liquid absorbent-refrigerant solution and superheated vapor to a high pressure. A generator extracts heat from the volume to be cooled by desorption and evaporation of the refrigerant from the high concentration solution in fluid connection with the inlet of the compressor. An absorber releases heat to surroundings by absorbing and condensing refrigerant vapor back into the liquid solution. A throttle valve controls the flow and reduces the pressure of the working fluid is in fluid connection with the absorber and the generator.
