ShareSummary
High temperature heat pump (HTHP) is an effective equipment to recovery industrial waste heat and it has a wide application potential. The choice of refrigerant has important influence on the efficiency of HTHP. In this paper, the performance parameters of the mixture refrigerant R600/R245fa using in HTHP were tested. Compared with the R245fa, the mixture refrigerant R600/R245fa has higher heating capacity and lower COP. But the COP of the HTHP system also can maintain above 3.0 when the temperature of condenser outlet water is at 100°C and 35°C temperature lift. Analysis shows that R600/R245fa is suitable for HTHPs with higher condenser outlet water temperature and heating capacity demand. And its low GWP also has good environmental benefits.
