Abstract：
Presents the special requirements of the refrigerant for hightemperature heat pumps. Develops a ternary mixture named HTR01 with good combination property by studying its basic character, material compatibility, oil solubility and flammability, and develops a 300 kW unit. A field measurement shows that the unit operates stable and the outlet water temperature of the condenser can reach to about 85 ℃. So the unit has higher coefficient of performance and well market prospect.
