Potential of non-azeotropic refrigerant mixture as working refrigerant in hot water heat pumps.

Author(s) : SMIT F. J., MEYER J. P.

Summary

The refrigerant that is mostly used in hot water heat pumps is R22. It supplies hot water at temperatures of 60 to 65 deg C. In this study it is theoretically shown that a non-azeotropic refrigerant mixture of R22 and R142b has the potential to increase the COP, reduce the pressure ratio of the compressor, maintain chemical stability of refrigerant and lubrication oil, increase heating capacity and display the feature of varying the heating capacity with load.
