Abstract

The influence of regime parameters and effects of their interaction on the energy efficiency of a supercritical R744 cycle refrigeration machine and heat pumps is analyzed. The non-linear connections between the parameters of a supercritical cycle are detection. The minimum and maximum of limiting temperature of supercritical cycle are determined. New regression dependences for the calculation of the maximum coefficient of performance and optimum discharge pressure in supercritical cycles are developed.
