[0026] The output end of the compressor 11 is connected to the input end of the power reheating module 12, and the output end of the power reheating module 12 is connected to the input end of the expansion valve 14.

[0027] The input ends of the power precooling module 13 and the assisted evaporator 15 are connected in parallel to the output end of the expansion valve 14, and the output ends of the power precooling module 13 and the assisted evaporator 15 are connected to the input end of the compressor 11.

[0028] The technical effect of the present solution is that the assisted evaporator 15 is added, when the inlet air temperature is low and the heat absorption of the power precooling module 13 is insufficient, the assisted evaporator 15 can fully absorb the heat in the environment, so that the compressor 11 system can fully supplement the heat, thereby facilitating the normal work of the compressor 11 system.

[0029] Among them, the medium in the power reheating module 12 is heated and liquefied. The medium in the power precooling module 13 absorbs heat and gasifies.

[0030] As an embodiment of the present embodiment, a liquid accumulator 16 is installed between the input end of the expansion valve 14 and the output end of the power reheating module 12.

[0032] As an embodiment of the present embodiment, the power temperature regulation system further comprises a shut-off valve 18, which is used to control the flow state of the medium in the auxiliary evaporator 15. In this scheme, when the shut-off valve 18 is opened, the medium in the auxiliary evaporator 15 flows and exchanges heat with the environment. When the shut-off valve 18 is closed, the medium in the auxiliary evaporator 15 does not flow, and it is almost impossible to exchange heat with the environment.

[0040] In the air duct 24, the components are arranged as follows:

[0041] The powered precooling module 13 and the unpowered precooling module 22 are located between the air inlet 25 and the surface cooler 20, so as to facilitate the powered precooling module 13 and the unpowered precooling module 22 to absorb heat from the flowing air.
