摘要：

In order to improve the thermal performance of a high temperature heat pump system, to realize the efficient heat recovery of industrial waste heat, and to make the combined utilization of low and medium temperature heat sources, a high temperature heat pump system with a double heat source cascade is proposed, which can absorb heat from industrial waste heat and the system is capable of heating water up to the required high temperature. The performance of the sys-tem is tested and analyzed. It is found that the inlet temperature of the medium temperature heat source has a significant impact on the performance of the heat pump system under working mode of the medium and low temperature heat sources. When the inlet temperature of the intermediate temperature heat source rises from 42 & DEG;C to 53 & DEG;C, the heating capacity of the cascade heat pump increas-es by 18.6%, and its performance coefficient increases by 8.9%. This paper pro-vides a reference for the high efficiency of the cascade high temperature heat pump technology.
