“…The new heat pump system could heat hot water to 81.34 • C. Yang [55] introduced life cycle cost (LCC) to study the influence of internal parameters of a two-stage absorption heat pump on economy, and the study revealed that the evaporator temperature T0 had the greatest influence on LCC. Balderas-Sanchez [56] compared the double-stage double-effect absorption heat pump with the double-effect absorption heat pump, and found that the double-stage double-effect heat pump had lower performance, but the temperature lift was significantly increased, which could reach 82 • C.…”

The high-temperature heat pump, as a low-carbonization technology, has broad application prospects in replacing boiler heating, reducing carbon dioxide emissions, and improving the energy utilization efficiency. In this paper, the working fluid, cycle process, key equipment (compressor), and application scenarios of high-temperature heat pumps are introduced in detail. Firstly, the research direction of the working fluid is introduced and the existing working fluid substitution is analyzed and summarized. Then, the characteristics of different heat pump cycles such as compression, absorption, and hybrid heat pumps are introduced. In the aspect of key equipment, the application range and research status of different types of compressors are emphatically introduced. Finally, the application scenario of high-temperature heat pumps is prospected. In addition to the application of industrial heating, it is often used for heat storage to improve the regulatory characteristics of the system. The new heat pump electricity storage system has great application potential in the field of renewable energy consumption. Based on the above analysis of high-temperature heat pumps, four development prospects are put forward: low-Global-Warming-Potential (GWP) working fluid; cycles of temperature lift greater than 80 °C; a compressor with better high-temperature performance; and circulation characteristics of heat pump electricity storage.
