[0037] like figure 1 As shown, this embodiment provides a waste heat recovery heat pump system, which has a heat pump cycle main circuit, which includes a compressor 1, a first heat exchange side of a condenser 2, an economizer 6 connected in sequence through a refrigerant pipeline The fluid heat exchange circuit formed by the first heat exchange side, the first throttle valve 3-1 and the first heat exchange side of the evaporator 4, wherein the second heat exchange side of the evaporator 4 is connected to the fluid side of the waste heat source, that is, the external waste heat fluid. The second heat exchange side of the condenser 2 is connected to the circulation loop of the use fluid side. In order to use the fluid circulation loop to transport high-temperature fluid, it should be noted that the use of the fluid side here refers to the circulation of the use end of the high-temperature fluid output by the heat pump system. Circuit, high temperature fluid contains high temp...

[0046] like figure 2 As shown, this embodiment provides a waste heat recovery heat pump system. This embodiment is basically the same as the above-mentioned first embodiment, and the structure and working principle are also the same. The difference is that the above-mentioned supplementary liquid enters the first subcooler 5- A fluid preheater 15 is provided on the path before 1 , and at the same time, the waste heat fluid at the output end of the second heat exchange side of the evaporator 4 also passes through the fluid preheater 15 . That is, the first heat exchange side of the fluid preheater 15 is connected to the waste heat fluid, and the second heat exchange side of the fluid preheater 15 is connected to the supplementary liquid. It should be noted that the supplementary liquid in this embodiment can be tap water, and the tap water is exchanged with the waste heat fluid through the fluid preheater 15, and the waste heat of the waste heat fluid is fully utilized to preh...

[0048] like image 3 As shown in the figure, this embodiment provides a waste heat recovery heat pump system. This embodiment is basically the same as the above-mentioned second embodiment, and the structure and working principle are also the same. The difference is that the second heat exchange side of the condenser 2 is directly set at a high temperature in fluid storage tank 8-1. This is to further improve the working efficiency of the condenser 2, so that the heat release effect of the condenser 2 is optimal, the heat loss is reduced, and the energy saving effect is better and more remarkable.
