At present, with the rapid development of the world economy, the consumption of energy is increased sharply, and meanwhile, the whole world is troubled constantly by environmental pollution generated in the development process, and the energy and environmental problems become hot spots concerned all over the world. The realization of energy conservation, emission reduction and environmental protection while ensuring the stable development of society has also become a consensus all over the world.
The energy saving not only depends on reducing the energy consumption in the social production and living process, but also promotes the low-grade energy in the production and living process to recycle again, and improves the comprehensive utilization efficiency of primary energy, which is also one of important means for energy saving. As disclosed in patent publication No. CN105928252B, the heat pump is a system for effectively recovering low-grade energy, and it can improve the utilization efficiency of energy, reduce the consumption of high-grade energy, and alleviate the pressure of energy crisis, and is widely used in the production and life of society.

Meanwhile, the temperature of heat energy required in industrial production and life is higher and higher at present, the heat energy is basically utilized in three modes of low-pressure steam, high-pressure steam and high-temperature hot water, but the heat supply temperature of a plurality of heat pumps is low, only one heat output mode can be provided in the actual use process, and the value of the heat pumps in the actual use process is severely limited. Therefore, the problems to be solved in the heat pump system industry at present are solved by researching and using the environment-friendly circulating working medium, improving the heat supply temperature of the heat pump system and enriching the heat energy output mode of the heat pump system in practical application.
