Experimental study of the dynamic behaviour of non-azeotropic binary mixtures in heat pumps.

Type of article: Article

Summary

The dynamic behaviour characteristics of some non-azeotropic refrigerant binary mixtures have been experimentally studied at various concentrations. The study was performed on a water-air heat pump during the heating mode under start-up conditions. The results presented in the study showed that the state of the non-azeotropic refrigerant mixture and its composition and concentration have a significant effect on the heat pump performance during start-up. In addition, the study demonstrated that non-azeotropic refrigerant mixtures could be potential CFC substitutes in heat pump applications.
