The analysis of the supercritical cycles of refrigeration machines and heat pumps by means of the generalized dependences
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 expedien...
