To balance heating performance and driving range in electric vehicles, heat pump air conditioning is one of the best options. However, heat pump air conditioning systems have more components than traditional air conditioning systems, resulting in larger space requirements and more connecting pipes.

Another portion of the refrigerant enters the battery cooler after being throttled by the first electronic expansion valve. After heat exchange in the battery cooler, the refrigerant enters the liquid receiver tank through the second valve island. The two portions of refrigerant merge and flow out from the second outlet back to the compressor.
[0020] As an optional technical solution for the integrated module, in the hot gas bypass mode, the refrigerant from the vehicle condenser enters the first valve island through the first inlet, bypasses the normally open solenoid valve, and enters the first electronic expansion valve through the normally closed solenoid valve. After being throttled by the first electronic expansion valve, the refrigerant enters the battery cooler.

After exiting the compressor, a portion of the refrigerant enters the second valve island through the third inlet connected to the hot gas bypass circuit. After being throttled by the second electronic expansion valve, it merges with the refrigerant from the battery cooler and enters the liquid receiver tank, then flows out through the second outlet back to the compressor.
[0021] The beneficial effects of this utility model are:

[0032] This embodiment provides an integrated module that integrates the refrigerant-side components of the automotive air conditioning system, saving on piping connections and layout between components, occupying little space, having a compact structure, and high assembly efficiency; and undertaking the functions of cooling, heating and dehumidification of the automotive air conditioning system.
[0033] Specifically, the integrated module is located on the refrigerant side of the automotive air conditioning system and includes a mounting bracket 1, a liquid-cooled condenser 7, a battery cooler 12, a first valve island 2, and a second valve island 10. The mounting point of the mounting bracket 1 is connected to the vehicle mounting point; the liquid-cooled condenser 7 is fixed to the mounting bracket 1, and the refrigerant can exchange heat with the coolant in the liquid-cooled condenser 7 to condense and dissipate heat; the battery cooler 12 is fixed to the mounting bracket 1, and the refrigerant can exchange heat with the coolant in the battery pack in the battery cooler 12 to evaporate and absorb heat; the liquid reservoir 11 is fixed to the mounting bracket 1, and the refrigerant can undergo gas-liquid separation in the liquid reservoir 11. One side of the bottom of the first valve island 2 is connected to the liquid-cooled condenser 7, and the other side is connected to the battery cooler 12. One inlet of the second valve island 10 is connected to the refrigerant outlet of the battery cooler 12, and the outlet of the second valve island 10 is connected to the inlet of the liquid storage tank 11. By selectively opening and closing the valves on the first valve island 2 and the second valve island 10, the vehicle air conditioning system can respectively achieve the single passenger compartment cooling mode, single battery cooling mode, dual cooling mode of passenger compartment and battery, single passenger compartment heating mode, single battery heating mode, dehumidification mode, and hot gas bypass mode.
[0034] Based on the above design, the first valve island 2 connects the liquid-cooled condenser 7 and the battery cooler 12, integrating them. One inlet of the second valve island 10 is connected to the refrigerant outlet of the battery cooler 12, and the outlet of the second valve island 10 is connected to the inlet of the liquid receiver 11, further integrating the battery cooler 12, the second valve island 10, and the liquid receiver 11. The liquid-cooled condenser 7, the battery cooler 12, and the liquid receiver 11 are all fixed on the mounting bracket 1, and the mounting point of the mounting bracket is connected to the vehicle mounting point to ensure the stability of the entire integrated module structure. Therefore, through the design of the mounting bracket 1, the first valve island 2, and the second valve island 10, the refrigerant-side components of the automotive air conditioning system (liquid-cooled condenser 7, battery cooler 12, and liquid receiver 11, with the first valve island 2 and the second valve island 10 concentrating various valves) are concentrated in this integrated module, saving on piping connections and layout between components, resulting in a small footprint, compact structure, and high assembly efficiency.
[0035] Secondly, by selectively opening and closing the valves on the first valve island 2 and the second valve island 10, it is possible to achieve single passenger compartment cooling mode, single battery cooling mode, dual cooling mode of passenger compartment and battery, single passenger compartment heating mode, single battery heating mode, dehumidification mode and hot gas bypass mode. Therefore, this integrated module undertakes the functions of cooling, heating and dehumidification of the automotive air conditioning system.
[0036] It should be noted that this automotive air conditioning system also includes an in-vehicle condenser, an in-vehicle evaporator, and a compressor. The various functional modes of this automotive air conditioning system are explained in detail below:
[0037] In the single-occupant-cabin cooling mode, the refrigerant from the vehicle's condenser enters the liquid-cooled condenser 7 through the first valve island 2. After exchanging heat with the coolant in the liquid-cooled condenser 7 to condense and dissipate heat, the refrigerant enters the vehicle's evaporator through the first valve island 2 again. In the vehicle's evaporator, the refrigerant exchanges heat with the air inside the vehicle to evaporate and absorb heat before flowing out. It then enters the liquid receiver 11 through the second valve island 10. In the liquid receiver 11, gas and liquid are separated (to prevent liquid from entering the compressor), and finally the refrigerant returns to the compressor, thus completing the single-occupant-cabin cooling.
[0038] In single-battery cooling mode, the refrigerant from the vehicle's condenser enters the liquid-cooled condenser 7 through the first valve island 2. After exchanging heat with the coolant in the liquid-cooled condenser 7 to condense and dissipate heat, the refrigerant re-enters the first valve island 2 and then enters the battery cooler 12 after being throttled in the first valve island 2. After exchanging heat with the coolant in the battery cooler 12, the refrigerant enters the liquid receiver 11 through the second valve island 10 and finally returns to the compressor, thus completing single-battery cooling.
[0039] The system employs a dual-cooling mode for both the passenger compartment and the battery. Refrigerant from the in-vehicle condenser enters the liquid-cooled condenser 7 via the first valve island 2. After exchanging heat with the coolant in the liquid-cooled condenser 7 to dissipate heat through condensation, the refrigerant re-enters the first valve island 2. A portion of the refrigerant bypasses the throttling on the first valve island 2 and flows directly out of the first valve island 2 into the in-vehicle evaporator. In the in-vehicle evaporator, the refrigerant exchanges heat with the air inside the vehicle to absorb heat through evaporation before flowing out and then through the second valve island 10 into the receiver 11. Another portion of the refrigerant is throttled on the first valve island 2 before flowing out of the first valve island 2 and into the battery cooler 12. After exchanging heat with the coolant in the battery cooler 12, it re-enters the receiver 11 via the second valve island 10. The two portions of refrigerant merge in the receiver 11 and return to the compressor, thus completing the dual-cooling of the passenger compartment and the battery.
[0040] In the single-occupant compartment heating mode, the refrigerant coming out of the vehicle condenser enters the first valve island 2. After being throttled in the first valve island 2, the refrigerant flows out of the first valve island 2 and enters the battery cooler 12. After exchanging heat with the coolant in the battery cooler 12, the refrigerant enters the liquid storage tank 11 through the second valve island 10 and finally returns to the compressor, thus completing the heating of the single-occupant compartment.
[0041] In single-battery heating mode, the refrigerant from the vehicle condenser enters the liquid-cooled condenser 7 through the first valve island 2. After exchanging heat with the coolant in the liquid-cooled condenser 7 to condense and dissipate heat, the refrigerant re-enters the first valve island 2, bypasses the throttling on the first valve island 2, and flows out into the vehicle evaporator. After exchanging heat with the vehicle air in the vehicle evaporator to evaporate and absorb heat, the refrigerant flows out, enters the liquid receiver 11 through the second valve island 10, and finally returns to the compressor, thus completing the single-battery heating.
[0042] It should be noted that the refrigerant circuit of this single-battery heating mode is the same as that of the single-occupant cabin cooling mode, but the coolant circuit is different.
[0043] In dehumidification mode, the refrigerant from the condenser inside the vehicle enters the first valve island 2. A portion of the refrigerant bypasses the throttling on the first valve island 2 and flows directly out of the first valve island 2 and into the vehicle evaporator. The refrigerant exchanges heat with the air inside the vehicle in the vehicle evaporator to evaporate and absorb heat before flowing out, and then enters the liquid receiver 11 through the second valve island 10. Another portion of the refrigerant is throttled on the first valve island 2 and then flows out of the first valve island 2 and into the battery cooler 12. After exchanging heat with the coolant in the battery cooler 12, it enters the liquid receiver 11 through the second valve island 10. The two portions of refrigerant merge and flow out back to the compressor, thus completing the dehumidification process.
[0044] In the hot gas bypass mode, the refrigerant from the vehicle's condenser enters the first valve island 2. After being throttled in the first valve island 2, it enters the battery cooler 12. After exchanging heat with the coolant in the battery cooler 12, the refrigerant enters the receiver tank 11 through the second valve island 10. After gas-liquid separation in the receiver tank 11, it returns to the compressor. A portion of the refrigerant that returns to the compressor enters the second valve island 10. After being throttled in the second valve island 10, it merges with the refrigerant from the battery cooler 12 and enters the receiver tank 11. Finally, it returns to the compressor, thus completing the hot gas bypass mode.
[0045] Optionally, the first valve island 2 is equipped with a normally open solenoid valve 3, a normally closed solenoid valve 4, a one-way valve 5, and a first electronic expansion valve 6. The function mode switching of the automotive air conditioning system is achieved through the normally open solenoid valve 3, normally closed solenoid valve 4, and one-way valve 5, making switching simple. The first electronic expansion valve 6 throttles the refrigerant. The second valve island 10 is equipped with a second electronic expansion valve 8, which also throttles the refrigerant.
[0046] Optionally, the first valve island 2 is provided with a first inlet a and a first outlet b. The first inlet a is connected to the refrigerant outlet of the vehicle's condenser, and the first outlet b is connected to the refrigerant inlet of the vehicle's evaporator. The second valve island 10 is provided with a second inlet c and a third inlet e. The liquid receiver 11 is provided with a second outlet d. The second inlet c is connected to the refrigerant outlet of the vehicle's evaporator, the second outlet d is connected to the compressor, and the third inlet e is connected to the hot gas bypass circuit. The first inlet a, the first outlet b, the second inlet c, the second outlet d, and the third inlet e enable the connection between the integrated module and the vehicle's air conditioning system structure.
[0047] It should be noted that the integrated module also includes a pressure and temperature sensor 9, which is located on the second valve island 10. The pressure and temperature sensor 9 can measure the pressure and temperature of the inlet of the pipeline on the second valve island 10, such as the pressure and temperature of the second inlet c and the third inlet e.
[0048] Furthermore, in the single-occupant-cabin cooling mode, the refrigerant from the in-vehicle condenser enters the first valve island 2 through the first inlet a, and then enters the liquid-cooled condenser 7 through the normally open solenoid valve 3 on the first valve island 2. After the refrigerant condenses and dissipates heat in the liquid-cooled condenser 7, it re-enters the first valve island 2 through the one-way valve 5. The refrigerant bypasses the first electronic expansion valve 6 on the first valve island 2, flows out of the first valve island 2 from the first outlet b, and enters the in-vehicle evaporator. After evaporating and absorbing heat in the in-vehicle evaporator, the refrigerant flows sequentially through the second inlet c of the first valve island 2, the liquid receiver 11, and the second outlet d of the first valve island 2, and returns to the compressor.
[0049] In single-battery cooling mode, the refrigerant from the vehicle condenser enters the first valve island 2 through the first inlet a, and then enters the liquid-cooled condenser 7 through the normally open solenoid valve 3 on the first valve island 2. After the refrigerant condenses and dissipates heat in the liquid-cooled condenser 7, it enters the first valve island 2 again through the one-way valve 5. After being throttled by the first electronic expansion valve 6, the refrigerant enters the battery cooler 12 to exchange heat with the coolant, then enters the liquid receiver 11 through the second valve island 10, and finally returns to the compressor through the second outlet d.
[0050] In the dual-cooling mode of the passenger compartment and battery, the refrigerant from the condenser enters the first valve island 2 through the first inlet a, and then enters the liquid-cooled condenser 7 through the normally open solenoid valve 3 on the first valve island 2. After the refrigerant condenses and dissipates heat in the liquid-cooled condenser 7, it re-enters the first valve island 2 through the one-way valve 5. Part of the refrigerant bypasses the first electronic expansion valve 6 on the first valve island 2, flows out of the first valve island 2 through the first outlet b, and enters the evaporator inside the vehicle. After evaporating and absorbing heat in the evaporator, the refrigerant flows out and enters the liquid receiver 11 through the second inlet c. Part of the refrigerant enters the battery cooler 12 after being throttled by the first electronic expansion valve 6. After heat exchange in the battery cooler 12, the refrigerant enters the liquid receiver 11 through the second valve island 10. The two parts of the refrigerant merge in the liquid receiver 11 and return to the compressor through the second outlet d.
[0051] In single-occupant-cabin heating mode, the refrigerant from the condenser enters the first valve island 2 through the first inlet a, bypasses the normally open solenoid valve 3 on the first valve island 2, enters the first electronic expansion valve 6 through the normally closed solenoid valve 4, flows out of the first valve island 2 after being throttled by the first electronic expansion valve 6, and enters the battery cooler 12. After heat exchange in the battery cooler 12, the refrigerant enters the liquid receiver 11 through the second valve island 10, and then flows out through the second outlet d back to the compressor.
[0052] In single-battery heating mode, the refrigerant from the vehicle condenser enters the first valve island 2 through the first inlet a, and then enters the liquid-cooled condenser 7 through the normally open solenoid valve 3 on the first valve island 2. After the refrigerant condenses and dissipates heat in the liquid-cooled condenser 7, it enters the first valve island 2 again through the one-way valve 5. The refrigerant bypasses the first electronic expansion valve 6 on the first valve island 2, flows out of the first valve island 2 from the first outlet b, and enters the vehicle evaporator. After evaporating and absorbing heat in the vehicle evaporator, the refrigerant flows sequentially through the second inlet c, the liquid receiver 11, and the second outlet d, and returns to the compressor.
[0053] In dehumidification mode, the refrigerant from the condenser enters the first valve island 2 through the first inlet a, bypasses the normally open solenoid valve 3 and passes through the normally closed solenoid valve 4. Part of the refrigerant bypasses the first electronic expansion valve 6 and flows out of the first valve island 2 through the first outlet b and enters the evaporator inside the vehicle. After heat exchange in the evaporator, the refrigerant flows out and enters the liquid receiver 11 through the second inlet c. Part of the refrigerant enters the battery cooler 12 after being throttled by the first electronic expansion valve 6. After heat exchange in the battery cooler 12, the refrigerant enters the liquid receiver 11 through the second valve island 10. The two parts of the refrigerant merge and flow out from the second outlet d back to the compressor.
[0054] In hot gas bypass mode, the refrigerant from the vehicle condenser enters the first valve island 2 through the first inlet a, bypasses the normally open solenoid valve 3, and enters the first electronic expansion valve 6 through the normally closed solenoid valve 4. After being throttled by the first electronic expansion valve 6, the refrigerant enters the battery cooler 12. After heat exchange in the battery cooler 12, the refrigerant enters the liquid receiver 11 through the second valve island 10, and then flows out through the second outlet d back to the compressor. After the refrigerant comes out of the compressor, a portion of the refrigerant enters the second valve island 10 through the third inlet e connected to the hot gas bypass circuit. After being throttled by the second electronic expansion valve 8, it merges with the refrigerant coming out of the battery cooler 12 and enters the liquid receiver 11, and then flows out through the second outlet d back to the compressor.
