SELECTION OF OZONE-SAFE, NON-AZEOTROPIC REFRIGERANT MIXTURES FOR CAPACITY MODULATION IN RESIDENTIAL HEAT PUMPS.

Summary

THE PRIMARY PURPOSE OF THE WORK WAS TO PERFORM A COMPREHENSIVE SCREENING OF REFRIGERANT PAIRS WHICH COULD IMPROVE THE PERFORMANCE OF HEAT PUMP SYSTEMS BY MODULATING THEIR CAPACITY TO BETTER FOLLOW A BUILDING LOAD. SECONDARY GOALS WERE TO SELECT A MIXTURE WITH A GLIDING TEMPERATURE DIFFERENCE THAT MATCHES THAT OF THE HEAT TRANSFER FLUID AND A HIGHER CAPACITY RELATIVE TO R22. THE CONCLUSIONS WERE THAT MIXTURES OF R32/R124, R32/R142B, R143A/R124, R143A/R142B, AND R143A/C318 WERE THE BEST CANDIDATES. ALTHOUGH THE MIXTURES WERE TAILORED FOR RESIDENTIAL HEAT PUMPS WITH AN EMPHASIS ON CAPACITY MODULATION, THE SCREENING PROCESS COULD BE USED FOR OTHER REFRIGERATION APPLICATIONS.
