Résumé

The purpose of this study is to propose a new refrigeration cycle and to clarify the performance characteristics of the cycle. The authors defined a vapour compression refrigeration cycle based on the Ericsson cycle on a T-s diagram and a p-h diagram. They clarified the practical method employed of achieving isothermal compression and expansion processes through utilization of multi-stage adiabatic compressors and an ordinary expansion valve. Theoretical investigation of the cycle performance using a single stage compressor and an expansion valve demonstrated that COP values become maximum and constant when the dryness fraction is kept in a definite range. The calculation results of performance characteristics of 12 different but typical refrigerants under the conditions of -40°C evaporative temperature and 40°C condensing temperature showed distinct improvements in COP for most of the sampled refrigerants.
