Figure 1As shown, the vehicle-mounted air conditioning system of the utility model includes: air conditioning module 1, four-way reversing valve 5, first heat exchanger 21 and second heat exchanger 22.

[0078] Figure 2 The schematic diagram of the air conditioning module in the vehicle-mounted air conditioning system of the utility model. As shown in the figure, Figure 2As shown in the figure, in a preferred embodiment, the air conditioning module 1 comprises: a housing 10, having a partitioned air inlet assembly and a partitioned air outlet assembly, and forming a unique air flow channel communicating the partitioned air inlet assembly and the partitioned air outlet assembly. A double-effect heat exchanger 11 is arranged between the downstream of the partitioned air inlet assembly and the upstream of the partitioned air outlet assembly, the double-effect heat exchanger 11 comprising a plurality of regions capable of independently adjusting the heat source heat, each region having a corresponding heat exchange pipeline to partition the phase-change working medium flowing therethrough, but not limited thereto.

[0079] Figure 3 A schematic view of a variant of the air conditioning module in the vehicle-mounted air conditioning system of the present application. Referring to Figure 3 According to the air conditioning device shown in the figure, in some applications, a plurality of different air outlet temperatures need to be obtained in the same ventilation path (such as air flow blowing to the area above the chest of the occupant), which can be processed in a partitioned manner on the double-effect heat exchanger 11, such as Figure 3 The double-effect heat exchanger in the air conditioning box is divided into two or more regions, each region independently corresponding to a partitioned air outlet assembly, and a control valve is added in front of each region, and by adjusting the working medium flow in the partition, different final air outlet temperatures are realized, but not limited thereto.

[0080] In a preferred embodiment, the air conditioning module 1 further comprises: a fan 18 for generating air flow from the partitioned air inlet assembly to the partitioned air outlet assembly through the double-effect heat exchanger 11, but not limited thereto.

[0081] In a preferred embodiment, the air conditioning module 1 further comprises: the housing 10 forms a heat exchange air path through the double-effect heat exchanger 11. The vehicle interior air inlet 13 is formed at the first end of the heat exchange air path. The vehicle exterior air inlet 14 is formed at the first end of the heat exchange air path.

The third air outlet region 17 is formed at the second end of the heat exchange air path, but not limited thereto.

[0082] Referring to Figure 2 As shown in the figure, the double-effect heat exchanger 11 using an internal flow phase-change working medium (such as R134a) of the present application replaces the single or combined cold and heat sources between the evaporator, the heater core and the condenser. In refrigeration, the double-effect heat exchanger 11 internally flows the phase-change working medium with a lower pressure as a cold source to reduce the temperature of the flowing air flow. In heating, the double-effect heat exchanger 11 internally flows the phase-change working medium with a higher pressure as a heat source to increase the temperature of the flowing air flow. Because there is only one double-effect heat exchanger 11, the air flow can directly reach the target temperature by changing the pressure and flow of the phase-change working medium therein, without mixing hot air for heating as in the traditional automobile air conditioning module, so the air conditioning module of the present application no longer needs a temperature damper to control the air volume entering the heat source for mixing and heating.

[0083] A heat pump system is designed for the air conditioner of the vehicle, which contains seven working states:

[0084] (1) Working in air conditioning cooling mode;

[0085] (2) Working in battery cooling mode;

[0086] (3) Working in air conditioning cooling and battery cooling mode;

[0087] (4) Working in air conditioning heating mode;

[0088] (5) Working in air conditioning heating and battery cooling mode;

[0089] (6) Working in battery heating mode;

[0090] (7) Working in motor heating battery mode;

[0091] The seven working modes are introduced below by referring to the straight lines in the schematic diagrams in the attached drawings of the specification, Figure 1 , 4 , 5, 6, 7, 8, and 9. The straight lines in the schematic diagrams in the attached drawings of the specification, Figure 1 , 4 , 5, 6, 7, 8, and 9 represent the refrigerant flow lines in the state; the dashed lines represent the lines that are cut off in the state, and the refrigerant does not flow in the lines)

At this time, the vehicle-mounted air conditioning system of the utility model works in the air conditioning refrigeration mode. At this time, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 4 flows into the first heat exchanger 21 (water-cooled condenser) to condense and release heat, so as to achieve the effect of heating the cooling liquid on the other side of the heat exchanger. The condensed refrigerant is throttled through the first regulating valve 91 and evaporated and absorbs heat in the double-effect heat exchanger 11, so as to realize the cooling function of the air conditioning box. The refrigerant then flows through the gas-liquid separator 3 to ensure that all the discharged refrigerant is gas, and finally returns to the suction port of the compressor 4 to start the next cycle. In this mode, the cooling liquid circuit only has a high-temperature cooling liquid part, and the high-temperature cooling liquid circuit is mainly responsible for taking away the heat released by the refrigerant in the first heat exchanger 21 (water-cooled condenser) and the heat released by the driving motor 7, and releasing heat to the external environment through the third heat exchanger 23 (radiator).

At this time, the vehicle-mounted air conditioning system of the utility model works in the battery cooling mode. At this time, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 4 flows into the first heat exchanger 21 (water-cooled condenser) to condense and release heat, so as to heat the cooling liquid on the other side of the heat exchanger. The condensed refrigerant is throttled through the second regulating valve 92, evaporates and absorbs heat in the second heat exchanger 22 (battery 8 cooler) to achieve the effect of cooling the cooling liquid on the other side of the heat exchanger, then flows through the gas-liquid separator 3, ensures that all the refrigerant flowing into the evaporator is gas, and finally returns to the suction port of the compressor 4 to start the next cycle, thereby realizing the battery 8 cooling function. In this mode, the cooling liquid circuit can be divided into high-temperature and low-temperature two parts according to the cooling liquid temperature, wherein the high-temperature cooling liquid circuit is mainly responsible for taking away the heat released by the refrigerant condensation in the first heat exchanger 21 (water-cooled condenser) and the heat released by the driving motor 7, and releasing the heat through the third heat exchanger 23 (radiator); the low-temperature cooling liquid circuit is mainly responsible for transporting the cooled cooling liquid in the second heat exchanger 22 to the battery 8, so as to achieve the effect of cooling the battery 8.

At this time, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 4 flows into the first heat exchanger 21 (a water-cooled condenser) to condense and release heat, so as to heat the cooling liquid on the other side of the heat exchanger. The condensed refrigerant is throttled through the first regulating valve 91 and 2, absorbs heat in the double-effect heat exchanger 11 and the second heat exchanger 22 (the battery 8 cooler), so as to achieve the effect of cooling the passenger compartment and the battery 8. Then it flows through the gas-liquid separator 3 to ensure that all the refrigerant flowing into the evaporator is gas, and finally returns to the suction port of the compressor 4 to start the next cycle, thereby realizing the refrigeration of the air conditioning box and the cooling function of the battery 8. In this mode, the cooling liquid circuit can be divided into high-temperature and low-temperature parts according to the cooling liquid temperature, wherein the high-temperature cooling liquid circuit is mainly responsible for taking away the heat released by the refrigerant condensation in the first heat exchanger 21 (the water-cooled condenser) and the heat released by the driving motor 7, and releasing the heat through the third heat exchanger 23 (the radiator); the low-temperature cooling liquid circuit is mainly responsible for transporting the cooled cooling liquid in the second heat exchanger 22 to the battery 8, so as to achieve the effect of cooling the battery 8. In the high-temperature cooling liquid circuit, the cooling liquid cooled by the third heat exchanger 23 (the radiator) reaches the inlet of the first booster pump 93 through two three-way water valves, is pumped into the first heat exchanger 21 (the water-cooled condenser) to absorb the condensation heat released by the refrigerant on the other side, and the warmed cooling liquid reaches the inlet of the motor 7, the cooling liquid absorbs the heat emitted by the motor 7 to further increase the temperature, the high-temperature cooling liquid flows out of the motor 7, is cooled through the third heat exchanger 23 (the radiator) and starts the next cycle.

Figure 6, the first regulating valve 91 is turned on; the second regulating valve 92 is turned off; the first three-way valve 94 only conducts the gas-liquid separator 3 and the second three-way valve 95; the second three-way valve 95 only conducts the first three-way valve 94 and the first booster pump 93, the first heat exchanger 21, the third heat exchanger 23 and the double-effect heat exchanger 11 all work, and the vehicle is heated; and the second heat exchanger 22 does not work. At this time, the vehicle-mounted air conditioning system of the utility model works in the air conditioning heating mode. At this time, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor 4 flows into the double-effect heat exchanger 11 to release heat, achieves the function of air conditioning heating, and the condensed refrigerant is throttled through the first regulating valve 91, evaporated and absorbs heat through the first heat exchanger 21 (water-cooled evaporator), and achieves the effect of cooling the cooling liquid on the other side of the heat exchanger.
