Optimization of process parameters of refrigeration process for a refrigerant mixture

Abstract

This study optimizes refrigeration process parameters for a new refrigerant mixture. Grey relational analysis has been used to find the best process parameters that lead to a higher Coefficient of Performance and lower Compressor discharge temperature, lower Compressor Power, and lower Mass flow rate. A mixture of R152a-R290-R600-R600a is proposed as a refrigerant. The predicted results have been checked with confirmation tests. The results of the confirmation test are the same as the results that were predicted.
