Abstract

Аn efficiency of use of the regenerative heat exchanger in one-stage cycle with heat regeneration for different refrigerants has been considered. It has been shown that the use of a regenerative heat exchanger provides protection of the compressor from wet stroke and results in improvement of a number characteristics of refrigerating cycle efficiency.
