Résumé

High-temperature heat pump (HTHP) for industrial heating is regarded as effective solution to control down CO2 emissions significantly, however there are still limited solutions to provide heat pumps with large scale and high temperature lift, especially it is difficult to adopt low-GWP refrigerants in HTHP and ensure efficient heating. Due to the excellent thermodynamic properties and environment friendly behavior, the application of natural working fluids in HTHP is an inevitable choice. Based on literature review and our previous research work, it is found that water could be the best working fluid in various HTHP systems. With water as refrigerant, high temperature heat pump could yield 100°C temperature lift with satisfied COP values, the system could be closed cycle, combined closed and open systems, and even hybrid vapor compression and absorption systems.
