Summary

In the present study we have carried out the drop-in experiments of R410A, HFO-1234ze(E) and the mixture of 50mass%HFO-1234ze(E)/50mass%HFC-32 at heating mode, using a vapor compression heat pump system developed for R410A. It has found that in the case of mixture of 50mass%HFO-1234ze(E)/50mass%HFC-32 the COP value is little affected by the degree of subcooling at the condenser outlet and it is only about 7.5% lower thanthat of R410A at the same heating load of 2.8 kW. This reveals that mixtures of HFO-1234ze(E)/HFC-32 are considered to be applicable as low-GWP alternatives for R410A by adjusting the composition of the mixture and by reconsidering the design parameters of components of room air-conditioning system.
