Summary

This paper discusses the suitability of R1224yd(Z) as R245fa alternative for high temperature heat pump. A drop-in test was performed when R245fa was replaced with R1224yd(Z) in a commercialized high temperature heat pump for industrial use. The test was performed by just replacing the refrigerant without changing any other components. In addition, the compatibility data with refrigeration oil, O-ring and motor insulation were obtained. The drop-in test result indicates better performance than the predicted thermodynamic simulation. As for the compatibility with refrigeration oil, O-ring and motor insulation, there were no significant differences between R1224yd(Z) and R245fa. Overall, R1224yd(Z) can be used as R245fa alternative for high temperature heat pump because of its good thermodynamic and environmental properties.
