Abstract

The generalized dependences for the analysis of energy efficiency of a supercritical R744 cycle refrigeration mechine and heat pumps are developed. The influence of regime parameters of a supercritical cycle and effects of their interaction on the coefficient of performance is examined. The expediency of application of regeneration in the supercritical cycles, and also uses expender is estimated
