[0088] The external circulation device further includes: a radiator 22, a heater 32, a three-way valve 71 and a water pump 81.

[0089] The input end of the water pump 81 is connected to the second output end of the water-cooled condenser 31. The water pump 81 is configured to make the coolant in the external circulation device circulate.

[0090] The water pump 81 has its output end connected to the heater 32 and the radiator 22 respectively.

[0091] The output end of the heater 32 is connected to the first input end of the three-way valve 71. The heater 32 is configured to release the heat of the coolant into the air inside the vehicle in the heating state.

[0092] Optionally, the heater 32 includes a heater core.

[0096] The output end of the three-way valve 71 is connected to the second input end of the water-cooled condenser 31.

[0097] In some specific embodiments, as Figure 4 shown, the system further includes a cooling fan 23. The cooling fan 23 is serially arranged and adjacent to the condenser 21 and the radiator 22. The cooling fan 23 is configured to control the heat dissipation speed of the cooling fan 23 and the condenser 21. Using the control cooling fan 23 is beneficial to improving the air-conditioning performance.

[0098] As Figure 2 shown, in the embodiment of the present application, in the cooling state, in the internal circulation device, the first two-way valve 61 and the second two-way valve 62 are controlled to open, the third two-way valve 63 and the fourth two-way valve 64 are closed, and the first expansion valve 51, the second expansion valve 52 and the third expansion valve 53 are opened. Thus, a first internal circulation refrigeration circuit and a second internal circulation refrigeration circuit are formed. The first internal circulation refrigeration circuit includes the following reference numerals: 41, 11, 31, 61, 51, 21, 92, 53, 33, 62 and 41. The second internal circulation refrigeration circuit includes the following reference numerals: 41, 11, 31, 61, 51, 21, 92, 52, 34 and 41. In the external circulation device, the second input end and the output end of the three-way valve 71 are controlled to communicate, and the first input end is closed. Thus, a first external circulation refrigeration circuit is formed. The external circulation refrigeration circuit includes: the water-cooled condenser 31, the water pump 81, the radiator 22, the three-way valve 71 and the water-cooled condenser 31.

[0099] In the first internal circulation refrigeration circuit, when the cooling fan 23 starts to rotate, the compressor 11 starts to rotate, causing the refrigerant to flow from the liquid storage tank 41 into the compressor 11. The compressor 11 compresses the refrigerant and then inputs it into the water-cooled condenser 31. The refrigerant exchanges heat with the coolant circulating in the external circulation device for the first time in the water-cooled condenser 31, transferring the heat to the coolant. Then, part of the heat is released into the outdoor air through the radiator 22. The refrigerant then enters the outdoor condenser 21 through the first two-way valve 61 and the first expansion valve 51 for the second heat exchange, releasing part of the heat into the outdoor air. Then, the refrigerant cools the interior of the vehicle through the third expansion valve 53 and the evaporator 33 respectively. In the second internal circulation refrigeration circuit, the battery is cooled through the second expansion valve 52 and the Chiller 34, and finally returns to the liquid storage tank 41.

[0100] Specifically, by controlling the opening degrees of the second expansion valve 52 and the third expansion valve 53, the refrigerant flow rates in the first internal circulation refrigeration circuit and the second internal circulation refrigeration circuit can be adjusted to meet the different requirements of interior cooling and battery cooling. For example, closing the second expansion valve 52 and opening the third expansion valve 53 can achieve separate cooling of the interior of the vehicle; opening the second expansion valve 52 and closing the third expansion valve 53 can achieve separate cooling of the battery; opening the second expansion valve 52 and the third expansion valve 53 simultaneously can achieve simultaneous cooling of the interior of the vehicle and the battery.

[0101] Specifically, the rotation speeds of the compressor 11, the cooling fan 23, and the water pump 81 are controlled and adjusted according to the requirements of interior cooling and battery cooling.

[0102] As Figure 3 shown, in the heating state in the embodiment of the present application, in the internal circulation device, the first two-way valve 61 and the second two-way valve 62 are controlled to be closed, the third two-way valve 63 and the fourth two-way valve 64 are controlled to be opened, and the first expansion valve 51, the second expansion valve 52, and the third expansion valve 53 are controlled to be opened. Thus, a first internal circulation heating circuit and a second internal circulation heating circuit are formed. The first internal circulation heating circuit includes: a liquid storage tank 41, a compressor 11, a water-cooled condenser 31, a third two-way valve 63, a second expansion valve 52, an evaporator 33, a third one-way valve 93, a first expansion valve 51, an outdoor condenser 21, a fourth two-way valve 64, a first one-way valve 91, and a liquid storage tank 41; the second internal circulation heating circuit includes: a liquid storage tank 41, a compressor 11, a water-cooled condenser 31, a third two-way valve 63, a second expansion valve 52, an evaporator 33, a fourth one-way valve 94, a second expansion valve 52, a Chiller 34, and a liquid storage tank 41. In the external circulation device, the first input end of the three-way valve 71 and the output end of the three-way valve 71 are controlled to be connected, and the second input end is closed. Thus, an external circulation heating circuit is formed. The external circulation heating circuit includes: a water-cooled condenser 31, a water pump 81, a heater 32, a three-way valve 71, and a water-cooled condenser 31.

[0103] In the first internal circulation heating circuit, when the cooling fan 23 starts to rotate, the compressor 11 starts to rotate, causing the refrigerant to flow from the liquid storage tank 41 into the compressor 11. The compressor 11 compresses the refrigerant and then inputs it into the water-cooled condenser 31. The refrigerant undergoes the first heat exchange with the coolant circulating in the external circulation device in the water-cooled condenser 31, transferring the heat to the coolant. Then, the heat is released into the vehicle interior air through the heater 32 in the external circulation device. Subsequently, the refrigerant enters the evaporator 33 through the third two-way valve 63 and the third expansion valve 53 for the second heat exchange, and releases some heat into the vehicle interior air again through the evaporator 33. Then, the refrigerant enters the outdoor condenser 21 through the first expansion valve 51 respectively to absorb heat from the outside air. In the second internal circulation heating circuit, the refrigerant enters the Chiller 34 through the second expansion valve 52, absorbs heat from the electric drive and battery coolant, and then returns to the liquid storage tank 41.

[0104] Specifically, according to the ambient temperature, the waste heat of the electric drive and battery water circuit, and the heating demand, the opening degrees of the first expansion valve 51 and the second expansion valve 52 are controlled to adjust the refrigerant flow rates in the first internal circulation heating circuit and the second internal circulation heating circuit, enabling the implementation of air-source and water-source heat pumps. For example, closing the second expansion valve 52 and opening the first expansion valve 51 can achieve individual heating for the vehicle interior; opening the second expansion valve 52 and closing the first expansion valve 51 can achieve individual heating for the battery; opening both the second expansion valve 52 and the first expansion valve 51 simultaneously can achieve simultaneous heating for the vehicle interior and the battery.

[0105] Specifically, the rotation speeds of the compressor 11, the cooling fan 23, and the water pump 81 are controlled and adjusted according to the heating demand in the vehicle interior.

[0106] The embodiment of the present application provides an air-conditioning system for a new energy vehicle, which has the functions of secondary condensation and secondary throttling of the refrigerant, can improve the heat exchange efficiency, enhance the refrigeration effect of the air-conditioning system in high-temperature environments and the heating effect in low-temperature environments, and reduce the system energy consumption.

[0107] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0108] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
