Abstract

The stages in the cycle are compression, condensation, expansion and vaporisation-followed by recompression. The fluid used in the cycle is a non-azeotropic mixt. Each stage of the process is a multistage process to use the different condensation and evaporation characteristics of the various mixt. components. The heat removed from the mixt. as it condenses passes into a heating system. Heat for vaporising the liq. is taken from an external source such as the air, a stream or a lake. The use of the multistage process increases the system efficiency. It may be used efficiently where there is a big temp. difference between the hot and cold source. It is relatively simple in regard to the equipment needed and its control and regulation.
