DETAILED DESCRIPTION

[0059] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only for the purpose of explaining the present application, and cannot be understood as limiting the present application.

[0060] Reference is made below to Figures 1-9 An air conditioning system 1000 according to an embodiment of the present application is described below, which can be applied to a vehicle, but the present application is not limited thereto, and the air conditioning system 1000 can be applied to other devices in which the air conditioning system 1000 is required to be provided, and the present application is described by taking an example in which the air conditioning system 1000 is applied to a vehicle.

[0061] As shown in Figure 1 An air conditioning system 1000 according to an embodiment of the present application includes a first heat exchanger 1, a second heat exchanger 2, a third heat exchanger 3, a compressor 4, a collection tank 5, and an air duct assembly 500.

[0062] The first heat exchanger 1 has a first heat exchange interface 1a and a second heat exchange interface 1b. The second heat exchanger 2 has a third heat exchange interface 2a and a fourth heat exchange interface 2b. The third heat exchanger 3 has a fifth heat exchange interface 3a and a sixth heat exchange interface 3b. The compressor 4 has a compressor first inlet 4a, a compressor outlet 4b, and a compressor second inlet 4c. The collection tank 5 has a collection tank inlet 5a and a collection tank outlet 5b.

[0063] The compressor first inlet 4a is selectively communicated with one of the third heat exchange interface 2a, the fifth heat exchange interface 3a, and the first heat exchange interface 1a. The compressor second inlet 4c is selectively communicated with the first heat exchange interface 1a or the third heat exchange interface 2a. The compressor outlet 4b is selectively communicated with the fifth heat exchange interface 3a or the third heat exchange interface 2a. The second heat exchange interface 1b is selectively communicated with the collection tank outlet 5b. The fourth heat exchange interface 2b is selectively communicated with the collection tank inlet 5a or the collection tank outlet 5b. The sixth heat exchange interface 3b is selectively communicated with the collection tank inlet 5a or the collection tank outlet 5b.

[0064] The air duct assembly 500 comprises an air duct shell 50, the air duct shell 50 is internally formed with an assembly space 51, the assembly space 51 is internally provided with a mounting space 52, the first heat exchanger 1 is mounted in the mounting space 52, the air duct shell 50 is provided with an air outlet 53c, a first air inlet 53a and a second air inlet 53b, the air outlet 53c is in communication with the assembly space 51 and the second heat exchanger 2 is arranged at the air outlet 53c, the mounting space 52 is selectively in communication with the air outlet 53c, the first air inlet 53a is selectively in communication with the air outlet 53c or the mounting space 52, the second air inlet 53b is selectively in communication with the air outlet 53c or the mounting space 52, and the first air inlet 53a and the second air inlet 53b are selectively opened or closed.

[0065] Specifically, the first heat exchanger 1, the second heat exchanger 2 and the third heat exchanger 3 are all used for heat exchange between the heat exchange medium and the air, so that the heat exchange medium can absorb the heat in the air, thereby achieving the effect of increasing the temperature of the heat exchange medium and reducing the temperature of the air, or the air absorbs the heat of the heat exchange medium, thereby achieving the effect of reducing the temperature of the heat exchange medium and increasing the temperature of the air. Further, the heat exchange medium can be refrigerant, which is a substance that can easily change from liquid to gas by absorbing heat, and can easily change from gas to liquid by releasing heat. It should be noted that in some embodiments of the present application, the heat exchange medium is taken as an example of refrigerant, but the present application is not limited thereto.

[0066] Further, the compressor 4 has the function of increasing the pressure, and the compressor 4 is used for compressing the heat exchange medium. The collecting tank 5 is suitable for the second heat exchanger 2 and the third heat exchanger 3, so that when the heat exchange medium exchanges heat with the air through the second heat exchanger 2 and / or the third heat exchanger 3, the collecting tank 5 is used to collect the condensate water generated by the air when the heat exchange medium exchanges heat with the air, so that the condensate water is stored in the collecting tank 5, and when the heat exchange medium flows through the collecting tank 5, the heat exchange medium is suitable for exchanging heat with the condensate water stored in the collecting tank 5, thereby achieving the effect of supercooling the heat exchange medium and reducing the temperature of the heat exchange medium, achieving the effect of increasing the supercooling degree of the heat exchange medium, increasing the enthalpy of the air conditioning system 1000, and thereby improving the working performance of the air conditioning system 1000.

[0067] In some embodiments of the present application, as Figure 2As shown, the compressor outlet 4b is communicated with the fifth heat exchange interface 3a of the third heat exchanger 3, and the sixth heat exchange interface 3b of the third heat exchanger 3 is communicated with the collection tank inlet 5a, so that the heat exchange medium flows into the third heat exchanger 3 after being compressed by the compressor 4 to exchange heat with the air. When the heat exchange medium flows through the third heat exchanger 3, the heat exchange medium in the third heat exchanger 3 releases heat, thereby achieving the effects of reducing the temperature of the air and increasing the temperature of the heat exchange medium. After the heat exchange medium is heat-exchanged in the third heat exchanger 3, it flows to the collection tank 5. The heat exchange medium flows into the collection tank 5 from the collection tank inlet 5a, and exchanges heat with the condensed water stored in the collection tank 5, thereby achieving the effect of supercooling the heat exchange medium, thereby further reducing the temperature of the heat exchange medium.

[0068] Further, the collection tank outlet 5b is communicated with the second heat exchange interface 1b of the first heat exchanger 1, so that the heat exchange medium flows to the first heat exchanger 1 after being supercooled in the collection tank 5. The heat exchange medium flows into the first heat exchanger 1 from the second heat exchange interface 1b, and the heat exchange medium flows out of the first heat exchanger 1 from the first heat exchange interface 1a. During the process of the heat exchange medium flowing through the first heat exchanger 1, the heat exchange medium absorbs the heat of the air, thereby achieving the effects of reducing the temperature of the air and increasing the temperature of the heat exchange medium. In addition, due to the reduction of the temperature of the air, the water vapor contained in the air condenses, thereby achieving the effect of reducing the water content in the air. At the same time, the condensed water formed during the heat exchange process can flow into the collection tank 5 for storage to be used for supercooling the heat exchange medium.

[0069] Further, the first heat exchange interface 1a is communicated with the second inlet 4c of the compressor, so that the heat exchange medium after being heat-exchanged in the first heat exchanger 1 flows back to the compressor 4, thereby achieving the effect of circulating flow of the heat exchange medium. Thus, as shown, Figure 2 As shown, the heat exchange medium flows in sequence along the compressor outlet 4b, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the collection tank inlet 5a, the collection tank outlet 5b, the second heat exchange interface 1b, the first heat exchange interface 1a, and the second inlet 4c of the compressor. When the heat exchange medium flows through the first heat exchanger 1, it absorbs the heat of the air, thereby achieving the effects of reducing the temperature of the air and increasing the temperature of the heat exchange medium. After the heat exchange medium is heat-absorbed and evaporated, it flows back to the compressor 4 from the second inlet 4c of the compressor, thereby achieving the effect of supplementing the gaseous heat exchange medium into the compressor 4, thereby achieving the function of air supplementing and enthalpy increasing of the air conditioning system 1000, which is beneficial to improving the working performance of the air conditioning system 1000.

[0070] Furthermore, the outlet 5b of the collection tank is also connected to the fourth heat exchange interface 2b of the second heat exchanger 2, so that the heat exchange medium after being subcooled by the collection tank 5 flows to the second heat exchanger 2. The heat exchange medium flows into the second heat exchanger 2 from the fourth heat exchange interface 2b and flows out of the second heat exchanger 2 from the third heat exchange interface 2a. During the process of the heat exchange medium flowing through the second heat exchanger 2, the heat exchange medium absorbs heat from the air, thereby achieving the effect of lowering the air temperature and raising the temperature of the heat exchange medium. In addition, due to the reduction of the air temperature, the water vapor contained in the air condenses upon cooling, thereby achieving the effect of reducing the water content in the air. At the same time, the condensate formed during the heat exchange process can flow into the collection tank 5 for storage and use for subcooling of the heat exchange medium.

[0071] Furthermore, the third heat exchange port 2a is connected to the first inlet 4a of the compressor, so that the heat exchange medium processed by the second heat exchanger 2 flows back into the compressor 4, thereby achieving the effect of heat exchange medium circulation. Thus, as... Figure 2 As shown, when the heat exchange medium flows sequentially along the compressor outlet 4b, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the collection tank inlet 5a, the collection tank outlet 5b, the fourth heat exchange interface 2b, the third heat exchange interface 2a, and the compressor first inlet 4a, the heat exchange medium absorbs heat from the air during its flow through the second heat exchanger 2. This lowers the air temperature and raises the temperature of the heat exchange medium, allowing it to return from the compressor first inlet 4a to the compressor 4 after absorbing heat and evaporating. This achieves the effect of circulating the heat exchange medium, which is beneficial for improving the working performance of the air conditioning system 1000.

[0072] In summary, under the aforementioned operating conditions, the air conditioning system 1000 achieves the effect of lowering the air temperature and raising the temperature of the heat exchange medium during the flow of the heat exchange medium through the first heat exchanger 1, where the heat exchange medium absorbs heat from the air and is in an absorbing state. Similarly, during the flow of the heat exchange medium through the second heat exchanger 2, the heat exchange medium absorbs heat from the air and is in an absorbing state, again achieving the same effect. This results in the cooling effect of the air conditioning system 1000, which is beneficial for achieving a cooling mode for the passenger cabin. Furthermore, the air conditioning system 1000 also achieves the function of replenishing air and increasing enthalpy during the cooling process, thereby improving its overall performance.

[0073] In some embodiments of the present invention, such as Figure 3As shown, the compressor outlet 4b is communicated with the third heat exchange interface 2a of the second heat exchanger 2, and the fourth heat exchange interface 2b of the second heat exchanger 2 is communicated with the collection tank inlet 5a, so that the heat exchange medium flows into the second heat exchanger 2 after being compressed by the compressor 4 to exchange heat with the air. When the heat exchange medium flows through the second heat exchanger 2, the heat exchange medium in the second heat exchanger 2 releases heat, thereby achieving the effects of increasing the air temperature and reducing the heat exchange medium temperature. The heat exchange medium after the heat exchange treatment of the second heat exchanger 2 flows to the collection tank 5. The heat exchange medium flows into the collection tank 5 from the collection tank inlet 5a, and exchanges heat with the condensed water stored in the collection tank 5, thereby achieving the effect of supercooling the heat exchange medium, thereby reducing the heat exchange medium temperature.

[0074] Further, the collection tank outlet 5b is communicated with the second heat exchange interface 1b of the first heat exchanger 1, so that the heat exchange medium flows to the first heat exchanger 1 after being supercooled by the collection tank 5. The heat exchange medium flows into the first heat exchanger 1 from the second heat exchange interface 1b, and the heat exchange medium flows out of the first heat exchanger 1 from the first heat exchange interface 1a. During the process of the heat exchange medium flowing through the first heat exchanger 1, the heat exchange medium absorbs the heat of the air, thereby achieving the effects of reducing the air temperature and increasing the heat exchange medium temperature. In addition, due to the reduction of the air temperature, the water vapor contained in the air condenses, thereby achieving the effect of reducing the water content in the air. At the same time, the condensed water formed during the heat exchange process can flow into the collection tank 5 for storage to be used for supercooling the heat exchange medium.

[0075] Further, the first heat exchange interface 1a is communicated with the second inlet 4c of the compressor, so that the heat exchange medium after the heat exchange treatment of the first heat exchanger 1 flows back to the compressor 4, thereby achieving the effect of circulating flow of the heat exchange medium. Thus, as shown, Figure 3 As shown, the heat exchange medium flows in sequence along the compressor outlet 4b, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the collection tank inlet 5a, the collection tank outlet 5b, the second heat exchange interface 1b, the first heat exchange interface 1a, and the second inlet 4c of the compressor. When the heat exchange medium flows through the second heat exchanger 2, the heat exchange medium releases heat to the air, thereby achieving the effect of increasing the air temperature. When the heat exchange medium flows through the first heat exchanger 1, the heat exchange medium absorbs the heat of the air, thereby achieving the effects of reducing the air temperature and increasing the heat exchange medium temperature. After the heat exchange medium is evaporated by absorbing heat, the heat exchange medium flows back to the compressor 4 from the second inlet 4c of the compressor, thereby achieving the effect of supplementing the gaseous heat exchange medium into the compressor 4, thereby achieving the function of air conditioning system 1000 with air supplementing and enthalpy increasing, which is beneficial to improving the working performance of the air conditioning system 1000.

[0076] Further, the collecting tank outlet 5b is also communicated with the sixth heat exchange interface 3b of the third heat exchanger 3, so that the heat exchange medium after the subcooling treatment of the collecting tank 5 flows to the third heat exchanger 3, the heat exchange medium flows into the third heat exchanger 3 from the sixth heat exchange interface 3b, and the heat exchange medium flows out of the third heat exchanger 3 from the fifth heat exchange interface 3a, so that the heat exchange medium absorbs the heat of the air during the flow of the heat exchange medium through the third heat exchanger 3, and the heat exchange medium is evaporated by absorbing heat. Moreover, the fifth heat exchange interface 3a is communicated with the second inlet 4c of the compressor, so that the heat exchange medium flows back to the compressor 4, realizing the circulation of the heat exchange medium, which is beneficial to improve the working performance of the air conditioning system 1000. Thus, as shown in Figure 3 the heat exchange medium flows through the third heat exchanger 3 to absorb the heat of the air, realizing the evaporation of the heat exchange medium by absorbing heat, so that the heat exchange medium flows back to the compressor 4 from the first inlet 4a of the compressor after the evaporation by absorbing heat, thereby realizing the circulation of the heat exchange medium, which is beneficial to improve the working performance of the air conditioning system 1000.

[0077] In combination with the above, under the above working condition, the air conditioning system 1000 realizes the heating effect of the air conditioning system 1000, thereby being beneficial to realize the heating mode of the passenger cabin, in which the heat exchange medium releases heat to the air during the flow of the heat exchange medium through the second heat exchanger 2, the heat exchange medium is in the heat release state, realizing the effect of increasing the temperature of the air and reducing the temperature of the heat exchange medium, the heat exchange medium absorbs the heat of the air during the flow of the heat exchange medium through the first heat exchanger 1, the heat exchange medium is in the heat absorption state, realizing the effect of reducing the temperature of the air and increasing the temperature of the heat exchange medium, thereby realizing the heating effect of the air conditioning system 1000, and further being beneficial to realize the heating mode of the passenger cabin. Moreover, the air conditioning system 1000 can realize the function of air supplement and enthalpy increase during the heating process, thereby being beneficial to improve the working performance of the air conditioning system 1000.

[0078] In some embodiments of the present application, as shown in Figure 4 the third heat exchange interface 2a of the second heat exchanger 2 is communicated with the compressor outlet 4b, and the fourth heat exchange interface 2b of the second heat exchanger 2 is communicated with the collecting tank inlet 5a, so that the heat exchange medium after the pressure treatment of the compressor 4 can flow into the second heat exchanger 2 to exchange heat with the air, the heat exchange medium releases heat in the second heat exchanger 2 when the heat exchange medium flows through the second heat exchanger 2, thereby realizing the effect of increasing the temperature of the air and reducing the temperature of the heat exchange medium, the heat exchange medium after the heat exchange treatment of the second heat exchanger 2 flows to the collecting tank 5, the heat exchange medium flows into the collecting tank 5 from the collecting tank inlet 5a, and the heat exchange medium exchanges heat with the condensed water stored in the collecting tank 5, thereby realizing the effect of subcooling of the heat exchange medium, so as to reduce the temperature of the heat exchange medium.

[0079] Further, the collecting tank outlet 5b is in communication with the second heat exchange interface 1b of the first heat exchanger 1, so that the heat exchange medium flows to the first heat exchanger 1 after the subcooling treatment of the collecting tank 5, the heat exchange medium flows into the first heat exchanger 1 from the second heat exchange interface 1b, and the heat exchange medium flows out of the first heat exchanger 1 from the first heat exchange interface 1a, so that the heat exchange medium absorbs the heat of the air in the process of flowing through the first heat exchanger 1, thereby achieving the effects of reducing the temperature of the air and increasing the temperature of the heat exchange medium, and due to the reduction of the temperature of the air, the water vapor in the air condenses, thereby achieving the effect of reducing the water content in the air, and at the same time, the condensed water formed in the heat exchange process can flow into the collecting tank 5 for storage for the subcooling of the heat exchange medium.

[0080] Further, the first heat exchange interface 1a is in communication with the first inlet 4a of the compressor 4, so that the heat exchange medium after the heat exchange treatment of the first heat exchanger 1 flows back to the compressor 4, thereby achieving the effect of circulating flow of the heat exchange medium. Thus, as shown in Figure 4 the heat exchange medium flows through the second heat exchanger 2 in the process of flowing through the second heat exchanger 2, thereby achieving the effects of increasing the temperature of the air and reducing the temperature of the heat exchange medium, so that the heat exchange medium absorbs the heat of the air in the process of flowing through the first heat exchanger 1, thereby achieving the effects of reducing the temperature of the air and increasing the temperature of the heat exchange medium, thereby facilitating the dehumidification effect of the air conditioning system 1000, and further facilitating the dehumidification mode of the passenger compartment. And the heat exchange medium after the heat absorption evaporation flows back to the compressor 4 from the first inlet 4a of the compressor 4, thereby achieving the effect of circulating flow of the heat exchange medium, which is conducive to improving the working performance of the air conditioning system 1000.

[0081] As shown in Figures 5-7 the air in the assembly space 51 can flow into the vehicle passenger compartment from the air outlet 53c. The first air inlet 53a is selectively in communication with the outside of the vehicle, so that when the first air inlet 53a is opened, the air outside the vehicle can flow into the assembly space 51 from the first air inlet 53a, and the second air inlet 53b is selectively in communication with the inside of the vehicle passenger compartment, so that when the second air inlet 53b is opened, the air in the vehicle passenger compartment can flow into the assembly space 51 from the second air inlet 53b.

[0082] Further, the air duct assembly can further comprise an auxiliary air door 60, which can be selectively opened or closed. When the auxiliary air door 60 is opened, the installation space 52 is in communication with the air outlet 53c. When the auxiliary air door 60 is closed, the installation space 52 is not in communication with the air outlet 53c, so as to selectively communicate the installation space 52 with the air outlet 53c.

[0083] Further, in some embodiments of the present application, as shown in Figure 2 When the air conditioning system 1000 is in cooling mode, the heat exchange medium flowing through the first heat exchanger 1 is in heat absorption state, so as to reduce the temperature of the air exchanged with the first heat exchanger 1. The heat exchange medium flowing through the second heat exchanger 2 is in heat absorption state, so as to reduce the temperature of the air exchanged with the second heat exchanger 2.

[0084] Further, as shown in Figure 5 The first air inlet 53a and the second air inlet 53b are both in open state, so that the air outside the vehicle and the air in the vehicle passenger compartment can both flow into the installation space 52. Further, the first air inlet 53a is in communication with the installation space 52, so that the air outside the vehicle flows into the installation space 52 and exchanges heat with the first heat exchanger 1, so as to reduce the temperature of the air flowing into the installation space 52. The installation space 52 is in communication with the air outlet 53c, so that the air exchanged with the first heat exchanger 1 flows to the air outlet 53c and exchanges heat with the second heat exchanger 2, so as to reduce the temperature of the air flowing into the installation space 52. The second air inlet 53b is in communication with the air outlet 53c, so that the air in the vehicle passenger compartment flows into the installation space 52 and flows out of the installation space 52 from the air outlet 53c, so as to exchange heat with the second heat exchanger 2 during the process of flowing through the installation space 52, so as to reduce the temperature of the air flowing through the installation space 52. Thus, the air outside the vehicle exchanges heat with the first heat exchanger 1 and the second heat exchanger 2 in sequence, and the air in the vehicle passenger compartment exchanges heat with the second heat exchanger 2, so as to reduce the temperature of the air flowing into the installation space 52. The air flowing into the installation space 52 flows into the vehicle passenger compartment from the air outlet 53c, so as to realize the effect that the air conditioning system 1000 has the passenger compartment cooling mixed air mode.

[0085] Further, as shown in Figure 5As shown, the first air inlet 53a is in an open state, and the second air inlet 53b is in a closed state, so that the vehicle exterior air can flow into the assembly space 51. Further, the first air inlet 53a is in communication with the installation space 52, so that the air flowing into the installation space 52 exchanges heat with the first heat exchanger 1, thereby achieving the effect of reducing the temperature of the air flowing into the installation space 52, and the installation space 52 is in communication with the air outlet 53c, so that the air after the heat exchange treatment of the first heat exchanger 1 flows to the air outlet 53c and exchanges heat with the second heat exchanger 2, thereby achieving the effect of reducing the temperature of the air flowing into the installation space 52 again. Thus, the vehicle exterior air flowing into the assembly space 51 exchanges heat with the first heat exchanger 1 and the second heat exchanger 2 in turn, achieving the effect of reducing the temperature of the air flowing into the assembly space 51, and the air flowing into the assembly space 51 flows into the vehicle passenger compartment from the air outlet 53c, thereby achieving the effect of the air conditioning system 1000 having a passenger compartment cooling external circulation mode.

[0086] Further, as shown in FIG. 6, Figure 6 the first air inlet 53a is in a closed state, and the second air inlet 53b is in an open state, so that the air in the vehicle passenger compartment can flow into the assembly space 51. Further, the second air inlet 53b is in communication with the installation space 52, so that the air in the vehicle passenger compartment flows into the installation space 52 and exchanges heat with the first heat exchanger 1, thereby achieving the effect of reducing the temperature of the air in the installation space 52, and the installation space 52 is in communication with the air outlet 53c, so that the air after the heat exchange treatment of the first heat exchanger 1 flows to the air outlet 53c and exchanges heat with the second heat exchanger 2, thereby achieving the effect of reducing the temperature of the air flowing into the installation space 52 again. Thus, the air in the vehicle passenger compartment exchanges heat with the first heat exchanger 1 and the second heat exchanger 2 in turn, achieving the effect of reducing the temperature of the air in the vehicle passenger compartment flowing into the assembly space 51, and the air flowing into the assembly space 51 flows into the vehicle passenger compartment from the air outlet 53c, thereby achieving the effect of the air conditioning system 1000 having a passenger compartment cooling internal circulation mode.

[0087] Further, in some embodiments of the present application, as shown in FIG. 6, Figure 3 when the air conditioning system 1000 is in a heating mode, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanging heat with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanging heat with the second heat exchanger 2.

[0088] Further, as shown in FIG. 6, Figure 6As shown, the first air inlet 53a and the second air inlet 53b are both in an open state, so that the vehicle exterior air and the vehicle passenger cabin air can both flow into the installation space 51. Further, the second air inlet 53b is in communication with the installation space 52, so that the air flowing into the installation space 52 exchanges heat with the first heat exchanger 1, thereby achieving the effect of cooling and dehumidifying the air in the installation space 52, which is conducive to reducing the risk of vehicle window glass fogging, and the installation space 52 is in communication with the air outlet 53c, so that the air processed by the first heat exchanger 1 exchanges heat with the second heat exchanger 2 through the air outlet 53c, thereby achieving the effect of increasing the temperature of the air exchanged with the second heat exchanger 2.

[0089] The first air inlet 53a is in communication with the air outlet 53c, so that the vehicle exterior air flows into the installation space 51 and flows out of the installation space 51 from the air outlet 53c, so as to exchange heat with the second heat exchanger 2 during the process of the vehicle exterior air flowing through the installation space 51, thereby achieving the effect of increasing the temperature of the air exchanged with the second heat exchanger 2. Thus, the vehicle passenger cabin air exchanges heat with the first heat exchanger 1 and the second heat exchanger 2 in turn, and the vehicle exterior air exchanges heat with the second heat exchanger 2, thereby achieving the effect of dehumidifying and warming the air flowing into the installation space 51, and the air flowing into the installation space 51 flows into the vehicle passenger cabin from the air outlet 53c, thereby achieving the effect of the air conditioning system 1000 having a passenger cabin heating mixed air mode.

[0090] It should be noted that in the existing working mode of the air conditioning system, in order to prevent the vehicle glass from fogging in winter heating, only the vehicle exterior air or a small amount of vehicle passenger cabin air mixed with the vehicle exterior air is usually delivered into the vehicle passenger cabin, thereby reducing the humidity of the air in the passenger cabin. However, using too much vehicle exterior air will affect the heating rate in the passenger cabin and increase the working energy consumption of the air conditioning system. Therefore, according to the air conditioning system 1000 of the present application, the air conditioning system 1000 can effectively improve the heating rate in the passenger cabin and reduce the working energy consumption of the air conditioning system 1000.

[0091] Further, as shown, Figure 6 The first air inlet 53a is in an open state, and the second air inlet 53b is in a closed state, so that the vehicle exterior air can flow into the installation space 51. Further, the first air inlet 53a is in communication with the air outlet 53c, so that the vehicle exterior air flows into the installation space 51 and flows out of the installation space 51 from the air outlet 53c, so as to exchange heat with the second heat exchanger 2 during the process of the vehicle exterior air flowing through the installation space 51, thereby achieving the effect of increasing the temperature of the air flowing into the installation space 51. Thus, the vehicle exterior air flowing into the installation space 51 exchanges heat with the second heat exchanger 2, and the air flowing into the installation space 51 flows into the vehicle passenger cabin from the air outlet 53c, thereby achieving the effect of the air conditioning system 1000 having a passenger cabin heating external circulation mode.

[0092] Further, as shown in FIG. 1 1, when the air conditioning system 1000 is dehumidifying, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanged with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanged with the second heat exchanger 2. Figure 4

[0093] Further, as shown in FIG. 1 1, when the air conditioning system 1000 is dehumidifying, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanged with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanged with the second heat exchanger 2. Figure 7 Further, as shown in FIG. 1 1, when the air conditioning system 1000 is dehumidifying, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanged with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanged with the second heat exchanger 2.

[0094] Figure 7 Further, as shown in FIG. 1 1, when the air conditioning system 1000 is dehumidifying, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanged with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanged with the second heat exchanger 2.

[0095] Further, as shown in FIG. 1 1, when the air conditioning system 1000 is dehumidifying, the heat exchange medium flowing through the first heat exchanger 1 is in an endothermic state, thereby reducing the temperature of the air exchanged with the first heat exchanger 1, and the heat exchange medium flowing through the second heat exchanger 2 is in an exothermic state, thereby increasing the temperature of the air exchanged with the second heat exchanger 2. Figure 7 ​​As shown, the first air inlet 53a is in a closed state, and the second air inlet 53b is in an open state, so that the air in the vehicle passenger compartment can flow into the installation space 51. Further, the second air inlet 53b communicates with the installation space 52, so that the air in the vehicle passenger compartment flows into the installation space 52 and exchanges heat with the first heat exchanger 1, so that the water vapor in the air flowing into the installation space 52 condenses when cooled, thereby achieving the effect of reducing the humidity of the air flowing into the installation space 52, and the installation space 52 communicates with the air outlet 53c, so that the air flowing into the installation space 51 exchanges heat with the second heat exchanger 2, thereby achieving the effect of warming the air that has been dehumidified, and avoiding the need to additionally provide a heating device for heating the air, which is conducive to reducing the energy consumption of the air conditioning system 1000, thereby achieving the effect that the air duct assembly 500 flows the air with appropriate temperature and water content into the vehicle passenger compartment, and the air conditioning system 1000 has the passenger compartment dehumidification internal circulation mode.

[0096] Therefore, in combination with the above, the air conditioning system 1000 according to the present application can have a passenger compartment cooling mode, a passenger compartment heating mode, and a passenger compartment dehumidification mode, wherein the passenger compartment cooling mode can include a passenger compartment cooling mixed air mode, a passenger compartment cooling external circulation mode, and a passenger compartment cooling internal circulation mode. The passenger compartment heating mode can include a passenger compartment heating mixed air mode and a passenger compartment heating external circulation mode. The passenger compartment dehumidification mode can include a passenger compartment dehumidification mixed air mode, a passenger compartment dehumidification external circulation mode, and a passenger compartment dehumidification internal circulation mode.

[0097] The air conditioning system 1000 also has the function of air supplementing and enthalpy increasing, which is conducive to improving the working performance of the air conditioning system 1000. Further, by providing the collection tank 5 for collecting condensate water, the heat exchange medium exchanges heat with the condensate water, which improves the subcooling degree of the heat exchange medium, thereby facilitating the increase of the enthalpy of the air conditioning system 1000, and further improving the working performance of the air conditioning system 1000.

[0098] In some embodiments of the present application, as Figure 1 As shown, the air conditioning system 1000 can further include a first control valve 6, the first control valve 6 having a first valve port 6a, a second valve port 6b, a third valve port 6c, and a fourth valve port 6d, the second valve port 6b selectively communicating with the first valve port 6a or the fourth valve port 6d, the fourth valve port 6d further selectively communicating with the third valve port 6c, the first valve port 6a communicating with the second inlet 4c of the compressor, the second valve port 6b communicating with the first heat exchange interface 1a, the third valve port 6c selectively communicating with the third heat exchange interface 2a or the fifth heat exchange interface 3a, and the fourth valve port 6d communicating with the first inlet 4a of the compressor.

[0099] Further, as Figure 2As shown, when the air conditioning system 1000 is in the passenger cabin cooling mode, the first valve port 6a is communicated with the second valve port 6b, so that the first heat exchange interface 1a is communicated with the second inlet 4c of the compressor, thereby realizing the effect that the outlet 4b of the compressor, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the inlet 5a of the collection tank, the outlet 5b of the collection tank, the second heat exchange interface 1b, the first heat exchange interface 1a and the second inlet 4c of the compressor are sequentially communicated.

[0100] The third valve port 6c is communicated with the fourth valve port 6d, so that the third heat exchange interface 2a is communicated with the first inlet 4a of the compressor, thereby realizing the effect that the outlet 4b of the compressor, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the inlet 5a of the collection tank, the outlet 5b of the collection tank, the fourth heat exchange interface 2b, the third heat exchange interface 2a and the first inlet 4a of the compressor are sequentially communicated. Thus, the effect of cooling of the air conditioning system 1000 is realized, and the passenger cabin cooling mode is facilitated.

[0101] Further, as shown in Figure 3 When the air conditioning system 1000 is in the passenger cabin heating mode, the first valve port 6a is communicated with the second valve port 6b, so that the first heat exchange interface 1a is communicated with the second inlet 4c of the compressor, thereby realizing the effect that the outlet 4b of the compressor, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the inlet 5a of the collection tank, the outlet 5b of the collection tank, the second heat exchange interface 1b, the first heat exchange interface 1a and the second inlet 4c of the compressor are sequentially communicated.

[0102] The third valve port 6c is communicated with the fourth valve port 6d, so that the fifth heat exchange interface 3a is communicated with the first inlet 4a of the compressor, thereby realizing the effect that the outlet 4b of the compressor, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the inlet 5a of the collection tank, the outlet 5b of the collection tank, the sixth heat exchange interface 3b, the fifth heat exchange interface 3a and the first inlet 4a of the compressor are sequentially communicated. Thus, the effect of heating of the air conditioning system 1000 is realized, and the passenger cabin cooling mode is facilitated.

[0103] Further, as shown in Figure 4 When the air conditioning system 1000 is in the passenger cabin dehumidification mode, the first valve port 6a is disconnected with the second valve port 6b, the third valve port 6c and the fourth valve port 6d, the third valve port 6c is disconnected with the second valve port 6b and the fourth valve port 6d, and the second valve port 6b is communicated with the fourth valve port 6d, so that the first heat exchange interface 1a is communicated with the first inlet 4a of the compressor, thereby realizing the effect that the outlet 4b of the compressor, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the inlet 5a of the collection tank, the outlet 5b of the collection tank, the second heat exchange interface 1b, the first heat exchange interface 1a and the first inlet 4a of the compressor are sequentially communicated. Thus, the effect of dehumidification of the air conditioning system 1000 is realized, and the passenger cabin dehumidification mode is facilitated.

[0104] In some embodiments of the present application, asFigure 1 As shown, the air conditioning system 1000 can further comprise a gas-liquid separator 7 connected between the fourth valve port 6d and the compressor first inlet 4a to communicate the fourth valve port 6d and the compressor first inlet 4a. Further, since the heat exchange medium can be evaporated by absorbing heat, the heat exchange medium can be completely evaporated from liquid state to form liquid state, or only partially evaporated to form gaseous state, and the gas-liquid separator 7 is used to separate the gaseous heat exchange medium from the liquid heat exchange medium. Moreover, by connecting the gas-liquid separator 7 between the fourth valve port 6d and the compressor first inlet 4a, so that in the process of the heat exchange medium flowing from the fourth valve port 6d to the compressor first inlet 4a, the gaseous heat exchange medium can directly pass through the gas-liquid separator 7 and flow into the compressor 4 from the compressor first inlet 4a for compression treatment, and the liquid heat exchange medium is stored in the gas-liquid separator 7, thereby avoiding the liquid heat exchange medium flowing into the compressor 4, and ensuring the working stability of the compressor 4.

[0105] Moreover, when the liquid heat exchange medium stored in the gas-liquid separator 7 is heated again, the heat exchange medium can change from liquid state to gaseous state, so that after the heat exchange medium changes from liquid state to gaseous state, the heat exchange medium can flow into the compressor 4 from the compressor first inlet 4a for compression treatment.

[0106] In some embodiments of the present application, as shown in Figure 1 As shown, the air conditioning system 1000 can further comprise a second control valve 8 having a fifth valve port 8a, a sixth valve port 8b, a seventh valve port 8c and an eighth valve port 8d, the fifth valve port 8a selectively communicating with the sixth valve port 8b or the seventh valve port 8c, the eighth valve port 8d also selectively communicating with the sixth valve port 8b or the seventh valve port 8c, the fifth valve port 8a communicating with the compressor outlet 4b, the sixth valve port 8b communicating with the fifth heat exchange interface 3a, the seventh valve port 8c communicating with the third heat exchange interface 2a, and the eighth valve port 8d communicating with the third valve port 6c.

[0107] Further, as shown in Figure 2 As shown, when the air conditioning system 1000 is in the passenger cabin refrigeration mode, the fifth valve port 8a communicates with the sixth valve port 8b to communicate the compressor outlet 4b and the fifth heat exchange interface 3a, the seventh valve port 8c and the eighth valve port 8d communicate to communicate the third heat exchange interface 2a and the compressor first inlet 4a, thereby realizing the effect that the compressor outlet 4b, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the collection tank inlet 5a, the collection tank outlet 5b, the fourth heat exchange interface 2b, the third heat exchange interface 2a and the compressor first inlet 4a are sequentially communicated. Thus, the effect of refrigeration of the air conditioning system 1000 is realized, and the passenger cabin refrigeration mode is facilitated.

[0108] Further, as shown in Figure 3As shown, when the air conditioning system 1000 is in passenger compartment heating mode, the fifth valve port 8a and the seventh valve port 8c are connected, so that the compressor outlet 4b is connected to the third heat exchange interface 2a. The sixth valve port 8b and the eighth valve port 8d are connected, so that the first heat exchange interface 1a is sequentially connected to the compressor second inlet 4c. This achieves the effect of sequentially connecting the compressor outlet 4b, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the collection tank inlet 5a, the collection tank outlet 5b, the sixth heat exchange interface 3b, the fifth heat exchange interface 3a, and the compressor first inlet 4a. This enables the air conditioning system 1000 to achieve heating, which in turn facilitates the achievement of passenger compartment cooling mode.

[0109] Furthermore, such as Figure 4 As shown, when the air conditioning system 1000 is in passenger compartment dehumidification mode, the fifth valve port 8a is disconnected from the sixth valve port 8b and the eighth valve port 8d, and the seventh valve port 8c is also disconnected from the sixth valve port 8b and the eighth valve port 8d. The fifth valve port 8a is connected to the seventh valve port 8c, so that the compressor outlet 4b is connected to the third heat exchange interface 2a. This achieves the sequential connection of the compressor outlet 4b, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the collection tank inlet 5a, the collection tank outlet 5b, the second heat exchange interface 1b, the first heat exchange interface 1a, and the compressor first inlet 4a. This achieves the dehumidification effect of the air conditioning system 1000, thus facilitating the implementation of the passenger compartment dehumidification mode.

[0110] In some embodiments of the present invention, such as Figure 1 As shown, the air conditioning system 1000 may further include: a third control valve 9, the third control valve 9 having a ninth valve port 9a, a tenth valve port 9b, an eleventh valve port 9c and a twelfth valve port 9d, the ninth valve port 9a being selectively connected to either the tenth valve port 9b or the eleventh valve port 9c, the twelfth valve port 9d being selectively connected to either the tenth valve port 9b or the eleventh valve port 9c, the ninth valve port 9a being connected to the sixth heat exchange interface 3b, the tenth valve port 9b being connected to the inlet 5a of the collection tank, the eleventh valve port 9c being connected to the outlet 5b of the collection tank, and the twelfth valve port 9d being connected to the fourth heat exchange interface 2b.

[0111] Furthermore, such as Figure 2 As shown, when the air conditioning system 1000 is in passenger compartment cooling mode, the ninth valve port 9a and the tenth valve port 9b are connected, so that the sixth heat exchange interface 3b is connected to the collection tank inlet 5a. The eleventh valve port 9c and the twelfth valve port 9d are connected, so that the collection tank outlet 5b is connected to the fourth heat exchange interface 2b. This achieves the sequential connection of the compressor outlet 4b, the fifth heat exchange interface 3a, the sixth heat exchange interface 3b, the collection tank inlet 5a, the collection tank outlet 5b, the fourth heat exchange interface 2b, the third heat exchange interface 2a, and the compressor first inlet 4a. This achieves the cooling effect of the air conditioning system 1000, which in turn facilitates the implementation of the passenger compartment cooling mode.

[0112] Further, as shown in Figure 3 the air conditioning system 1000 is in the passenger cabin heating mode, the ninth valve port 9a is communicated with the eleventh valve port 9c, so that the collection tank outlet 5b is communicated with the sixth heat exchange interface 3b, the tenth valve port 9b is communicated with the twelfth valve port 9d, so that the fourth heat exchange interface 2b is communicated with the collection tank inlet 5a, thereby realizing the effect that the compressor outlet 4b, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the collection tank inlet 5a, the collection tank outlet 5b, the sixth heat exchange interface 3b, the fifth heat exchange interface 3a, and the compressor first inlet 4a are sequentially communicated.

[0113] Further, as shown in Figure 4 the air conditioning system 1000 is in the passenger cabin dehumidification mode, the ninth valve port 9a is disconnected with the tenth valve port 9b, the eleventh valve port 9c and the twelfth valve port 9d, the eleventh valve port 9c is disconnected with the tenth valve port 9b and the twelfth valve port 9d, and the tenth valve port 9b is communicated with the twelfth valve port 9d, so that the fourth heat exchange interface 2b is communicated with the collection tank inlet 5a, thereby realizing the effect that the compressor outlet 4b, the third heat exchange interface 2a, the fourth heat exchange interface 2b, the collection tank inlet 5a, the collection tank outlet 5b, the second heat exchange interface 1b, the first heat exchange interface 1a, and the compressor first inlet 4a are sequentially communicated. Thus, the effect of dehumidifying the air conditioning system 1000 is realized, and the passenger cabin dehumidification mode is further facilitated.

[0114] In some embodiments of the present application, as shown in Figure 1 the air conditioning system 1000 can further include a first expansion valve 10 connected between the ninth valve port 9a and the sixth heat exchange interface 3b to make the ninth valve port 9a and the sixth heat exchange interface 3b conductive or disconnected. Further, the first expansion valve 10 can be configured as an electronic expansion valve, which can be selectively opened or closed, thereby realizing the effect that the heat exchange medium can selectively flow through the first expansion valve 10, and the opening size of the first expansion valve 10 can be infinitely adjusted, thereby controlling the flow of the heat exchange medium through the first expansion valve 10 to throttle the pressure of the heat exchange medium when it flows through the first expansion valve 10, and further realizing the effect of reducing the temperature of the heat exchange medium.

[0115] Further, as shown in Figure 2 the air conditioning system 1000 is in the passenger cabin refrigeration mode, since the heat exchange medium does not need to be cooled during the process of flowing from the sixth heat exchange interface 3b to the ninth valve port 9a, the first expansion valve 10 is in a closed state, so that the heat exchange medium does not need to flow through the first expansion valve 10 during the process of flowing from the sixth heat exchange interface 3b to the ninth valve port 9a, thereby facilitating the working effect of realizing the passenger cabin refrigeration mode.

[0116] Further, as shown in Figure 3As shown, when the air conditioning system 1000 is in the passenger cabin heating mode, the first expansion valve 10 is in the open state to facilitate the heat exchange medium flowing through the first expansion valve 10 in the process that the heat exchange medium cannot flow from the ninth valve port 9a to the sixth heat exchange interface 3b, thereby facilitating the working effect of the passenger cabin heating mode.

[0117] In some embodiments of the present application, as shown in Figure 1 As shown, the air conditioning system 1000 can further include a first one-way valve 11 connected between the ninth valve port 9a and the sixth heat exchange interface 3b to enable one-way conduction between the ninth valve port 9a and the sixth heat exchange interface 3b. Further, as shown in Figure 2 As shown, the flow direction of the first one-way valve 11 is from the sixth heat exchange interface 3b to the ninth valve port 9a, which can be understood as that when the heat exchange medium flows through the first one-way valve 11, the heat exchange medium can flow from the sixth heat exchange interface 3b to the ninth valve port 9a, but the heat exchange medium cannot flow from the ninth valve port 9a to the sixth heat exchange interface 3b.

[0118] Further, as shown in Figure 2 As shown, when the air conditioning system 1000 is in the passenger cabin cooling mode, the heat exchange medium flows from the sixth heat exchange interface 3b to the ninth valve port 9a, and since the first expansion valve 10 is in the closed state, the heat exchange medium flows through the first one-way valve 11 in the process that the heat exchange medium flows from the sixth heat exchange interface 3b to the ninth valve port 9a, thereby achieving the effect that the heat exchange medium flows from the sixth heat exchange interface 3b to the ninth valve port 9a.

[0119] Further, as shown in Figure 3 As shown, when the air conditioning system 1000 is in the passenger cabin heating mode, the heat exchange medium flows from the ninth valve port 9a to the sixth heat exchange interface 3b, and the first one-way valve 11 conducts in one direction, so the heat exchange medium cannot pass through the first one-way valve 11 in the process that the heat exchange medium flows from the ninth valve port 9a to the sixth heat exchange interface 3b, and the heat exchange medium flows through the first expansion valve 10, thereby facilitating the working effect of the passenger cabin heating mode.

[0120] In some embodiments of the present application, as shown in Figure 1As shown, the air conditioning system 1000 can further include a second expansion valve 12 connected between the twelfth valve port 9d and the fourth heat exchange interface 2b to make the twelfth valve port 9d and the fourth heat exchange interface 2b conductive or disconnected. Further, the second expansion valve 12 can be configured as an electronic expansion valve, which can be selectively opened or closed, so as to achieve the effect that the heat exchange medium can selectively flow through the second expansion valve 12, and the opening size of the second expansion valve 12 can be infinitely adjusted, so as to control the flow of the heat exchange medium through the second expansion valve 12, so as to throttle the pressure of the heat exchange medium when the heat exchange medium flows through the second expansion valve 12, thereby achieving the effect of reducing the temperature of the heat exchange medium.

[0121] Further, as shown in Figure 2 When the air conditioning system 1000 is in the passenger compartment cooling mode, since the heat exchange medium does not need to be cooled during the process of flowing from the sixth heat exchange interface 3b to the ninth valve port 9a, the first expansion valve 10 is in a closed state, so that the heat exchange medium does not need to flow through the first expansion valve 10 during the process of flowing from the sixth heat exchange interface 3b to the ninth valve port 9a, thereby facilitating the working effect of realizing the passenger compartment cooling mode.

[0122] Further, as shown in Figure 3 When the air conditioning system 1000 is in the passenger compartment heating mode, since the heat exchange medium needs to be cooled during the process of flowing from the ninth valve port 9a to the sixth heat exchange interface 3b, the first expansion valve 10 is in an open state, so that the heat exchange medium flows through the first expansion valve 10 during the process of flowing from the ninth valve port 9a to the sixth heat exchange interface 3b, thereby facilitating the working effect of the passenger compartment heating mode.

[0123] In some embodiments of the present application, as shown in Figure 1 The air conditioning system 1000 can further include a second one-way valve 13 connected between the twelfth valve port 9d and the fourth heat exchange interface 2b to make the twelfth valve port 9d and the fourth heat exchange interface 2b one-way conductive. Further, as shown in Figure 3 The flow direction of the second one-way valve 13 is from the fourth heat exchange interface 2b to the twelfth valve port 9d, which can be understood as that when the heat exchange medium flows through the second one-way valve 13, the heat exchange medium can flow from the fourth heat exchange interface 2b to the twelfth valve port 9d, but the heat exchange medium cannot flow from the twelfth valve port 9d to the fourth heat exchange interface 2b.

[0124] Further, as shown in Figure 2As shown, when the air conditioning system 1000 is in the passenger compartment cooling mode, since the heat exchange medium flows from the twelfth valve port 9d to the fourth heat exchange interface 2b, the second one-way valve 13 is unidirectionally open, and the heat exchange medium cannot pass through the second one-way valve 13. So, during the process of the heat exchange medium flowing from the twelfth valve port 9d to the fourth heat exchange interface 2b, the heat exchange medium flows through the second expansion valve 12, which helps to improve the working effect of the passenger compartment cooling mode.

[0125] Furthermore, such as Figure 3 As shown, when the air conditioning system 1000 is in passenger compartment heating mode, the heat exchange medium flows from the fourth heat exchange port 2b to the twelfth valve port 9d. Since the second expansion valve 12 is closed, the heat exchange medium flows through the second one-way valve 13 during the process of the heat exchange medium flowing from the fourth heat exchange port 2b to the twelfth valve port 9d, thereby achieving the effect of the heat exchange medium flowing from the fourth heat exchange port 2b to the fourth heat exchange port 2b.

[0126] Furthermore, such as Figure 4 As shown, when the air conditioning system 1000 is in the passenger compartment dehumidification mode, the heat exchange medium flows from the fourth heat exchange port 2b to the twelfth valve port 9d. Since the second expansion valve 12 is in the closed state, the heat exchange medium flows through the second one-way valve 13 during the process of the heat exchange medium flowing from the fourth heat exchange port 2b to the twelfth valve port 9d, thereby achieving the effect of the heat exchange medium flowing from the fourth heat exchange port 2b to the fourth heat exchange port 2b.

[0127] In some embodiments of the present invention, such as Figure 1 As shown, the air conditioning system 1000 may further include a third expansion valve 14, which is connected between the collection tank outlet 5b and the second heat exchange interface 1b to allow the collection tank outlet 5b and the second heat exchange interface 1b to be connected or disconnected. Further, the third expansion valve 14 may be configured as an electronic expansion valve, which can selectively open or close, thereby enabling the heat exchange medium to selectively flow through the third expansion valve 14. The opening size of the third expansion valve 14 can be infinitely adjusted to control the flow rate of the heat exchange medium through the third expansion valve 14, thereby throttling and pressurizing the heat exchange medium as it flows through the third expansion valve 14, and thus reducing the temperature of the heat exchange medium.

[0128] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, when the air conditioning system 1000 is in passenger compartment cooling mode, passenger compartment heating mode, and passenger compartment dehumidification mode, the third expansion valve 14 is in the open state because the heat exchange medium needs to be cooled during the process of flowing from the collection tank outlet 5b to the second heat exchange interface 1b. This allows the heat exchange medium to flow through the third expansion valve 14 during the process of flowing from the collection tank outlet 5b to the second heat exchange interface 1b, thereby improving the working effect of the passenger compartment cooling mode, passenger compartment heating mode, and passenger compartment dehumidification mode.

[0129] Furthermore, such as Figure 8 and Figure 9 As shown, the air conditioning system 1000 may also include a second mode for occupant cabin cooling and a second mode for occupant cabin heating.

[0130] Furthermore, such as Figure 2 and Figure 8 As shown, the difference between the passenger compartment cooling mode and the second passenger compartment cooling mode is that when the air conditioning system 1000 is in passenger compartment cooling mode, the third expansion valve 14 is open, allowing the heat exchange medium to flow from the collection tank outlet 5b to the second heat exchange interface 1b, and the heat exchange medium can flow back from the compressor second inlet 4c to the compressor 4, thereby replenishing the compressor 4 with gaseous heat exchange medium, thus enabling the air conditioning system 1000 to have a gas replenishment and enthalpy increase function. When the air conditioning system 1000 is in passenger compartment cooling mode, the third expansion valve 14 is closed, preventing the heat exchange medium from flowing from the collection tank outlet 5b to the second heat exchange interface 1b, and preventing the heat exchange medium from flowing back from the compressor second inlet 4c to the compressor 4, thus shutting down the gas replenishment and enthalpy increase function of the air conditioning system 1000. Therefore, according to the air conditioning system 1000 of this application, by setting the third expansion valve 14 to be selectively opened or closed, the effect of switching between passenger compartment cooling mode and passenger compartment cooling mode can be achieved.

[0131] Furthermore, such as Figure 3 and Figure 9As shown, the difference between the passenger compartment heating mode and the second passenger compartment heating mode is that when the air conditioning system 1000 is in passenger compartment heating mode, the third expansion valve 14 is open, allowing the heat exchange medium to flow from the collection tank outlet 5b to the second heat exchange interface 1b, and the heat exchange medium can flow back from the compressor second inlet 4c to the compressor 4, thereby replenishing the compressor 4 with gaseous heat exchange medium, and thus enabling the air conditioning system 1000 to have a gas replenishment and enthalpy enhancement function. When the air conditioning system 1000 is in passenger compartment heating mode, the third expansion valve 14 is closed, preventing the heat exchange medium from flowing from the collection tank outlet 5b to the second heat exchange interface 1b, and preventing the heat exchange medium from flowing back from the compressor second inlet 4c to the compressor 4, thus shutting down the gas replenishment and enthalpy enhancement function of the air conditioning system 1000. Therefore, according to the air conditioning system 1000 of this application, by setting the third expansion valve 14, which can be selectively opened or closed, the effect of switching between passenger compartment heating mode and passenger compartment heating mode can be achieved.

[0132] In some embodiments of the present invention, such as Figures 5-7 As shown, a first air duct 54a and a second air duct 54b are formed in the assembly space 51. One end of the first air duct 54a is connected to the first air inlet 53a, and the other end of the first air duct 54a is selectively connected to the air outlet 53c or the installation space 52. One end of the second air duct 54b is connected to the second air inlet 53b, and the other end of the second air duct 54b is selectively connected to the air outlet 53c or the installation space 52.

[0133] Furthermore, such as Figure 5 As shown, the other end of the first air duct 54a is connected to the installation space 52, and the other end of the second air duct 54b is connected to the air outlet 53c, so that the external air of the vehicle flows into the installation space 52 from the first air inlet 53a along the first air duct 54a, realizing the effect of heat exchange between the external air of the vehicle and the first heat exchanger 1 set in the installation space 52, so that the air in the passenger compartment of the vehicle flows from the second air inlet 53b to the air outlet 53c along the second air duct 54b, realizing the effect of heat exchange between the air in the passenger compartment of the vehicle and the second heat exchanger 2 set in the air outlet 53c, thereby helping to realize the effect of the air conditioning system 1000 having a passenger compartment cooling mixed air mode and a passenger compartment cooling external circulation mode.

[0134] Furthermore, such as Figure 6As shown, the other end of the first air duct 54a is connected to the air outlet 53c, and the other end of the second air duct 54b is connected to the installation space 52, so that the external air of the vehicle flows from the first air inlet 53a to the air outlet 53c along the first air duct 54a, realizing the effect of heat exchange between the external air of the vehicle and the second heat exchanger 2 located at the air outlet 53c, so that the air inside the vehicle passenger compartment flows from the second air inlet 53b into the installation space 52 along the second air duct 54b, realizing the effect of heat exchange between the air inside the vehicle passenger compartment and the first heat exchanger 1 located in the installation space 52, thereby helping to realize that the air conditioning system 1000 has the effects of passenger compartment cooling internal circulation mode, passenger compartment heating mixed air mode and passenger compartment heating external circulation mode.

[0135] Furthermore, such as Figure 6 As shown, the other end of the first air duct 54a is connected to the installation space 52, and the other end of the second air duct 54b is connected to the installation space 52, so that the air outside the vehicle and the air inside the vehicle passenger compartment flow into the installation space 52 along the first air duct 54a and the second air duct 54b respectively, so that the air outside the vehicle and the air inside the vehicle passenger compartment can exchange heat with the first heat exchanger 1 installed in the installation space 52. This is beneficial to realize that the air conditioning system 1000 has the effects of passenger compartment dehumidification mixed air mode, passenger compartment dehumidification external circulation mode and passenger compartment dehumidification internal circulation mode.

[0136] In some embodiments of the present invention, such as Figures 5-7 As shown, the air conditioning system 1000 may further include: a fourth heat exchanger 55, which is disposed in the assembly space 51. The fourth heat exchanger 55 has a first flow channel and a second flow channel for heat exchange. One end of the first flow channel is connected to the other end of the first air duct 54a, and the other end of the first flow channel is selectively connected to the air outlet 53c or the installation space 52. One end of the second flow channel is connected to the other end of the second air duct 54b, and the other end of the second flow channel is selectively connected to the air outlet 53c or the installation space 52.

[0137] Furthermore, when the two streams of air flow into the first and second channels respectively, the air in the first channel and the air in the second channel can exchange heat with each other. The air with higher temperature can transfer heat to the air with lower temperature, thereby regulating the temperature of the two streams of air. This helps to reduce the temperature difference between the two streams of air and improve the working effect of the air conditioning system 1000.

[0138] Furthermore, such as Figure 5As shown, the other end of the first airflow channel is connected to the installation space 52, and the other end of the second airflow channel is connected to the air outlet 53c, so that external air from the vehicle flows into the first airflow channel from the first airflow channel for heat exchange, and after heat exchange in the first airflow channel, the external air flows into the installation space 52 for heat exchange with the first heat exchanger 1 installed in the installation space 52. Similarly, air from the vehicle's passenger compartment flows into the second airflow channel from the second airflow channel from the second airflow channel for heat exchange, and after heat exchange in the second airflow channel, the air flows into the assembly space 51 for heat exchange with the second heat exchanger 2, thereby improving the working effect of the air conditioning system 1000 and enhancing the user experience.

[0139] Furthermore, the passenger compartment cooling mixed-air mode is generally used in high-temperature environments, where the temperature and humidity of the outside air are higher than those of the air inside the passenger compartment. For example... Figure 5 As shown, when the outside air flows into the first flow channel from the first air duct 54a for heat exchange, the outside air exchanges heat with the air inside the passenger compartment in the second flow channel. The outside air transfers heat to the air inside the passenger compartment, thereby reducing the temperature and humidity of the outside air and reducing the temperature difference between the outside air and the air inside the passenger compartment. This helps to improve the working effect of the passenger compartment cooling mixed air mode and improve the user experience.

[0140] Furthermore, such as Figure 6 As shown, the other end of the second flow channel is connected to the installation space 52, and the other end of the first flow channel is connected to the air outlet 53c, so that air from the vehicle's passenger compartment flows into the second flow channel from the second air duct 54b, and after heat exchange in the second flow channel, the air from the vehicle's passenger compartment flows into the installation space 52 to exchange heat with the first heat exchanger 1 installed in the installation space 52. Similarly, air from outside the vehicle flows into the first flow channel from the first air duct 54a to exchange heat, and after heat exchange in the first flow channel, the air from outside the vehicle flows into the assembly space 51 to exchange heat with the second heat exchanger 2, thereby improving the working effect of the air conditioning system 1000 and enhancing the user experience.

[0141] Furthermore, the passenger compartment heating and air mixing mode is generally used in low-temperature environments, where the air temperature and humidity inside the vehicle's passenger compartment are higher than those outside the vehicle. For example... Figure 6 As shown, when the air in the vehicle's passenger compartment flows into the second flow channel from the second air duct 54b for heat exchange, the air in the passenger compartment exchanges heat with the external air in the first flow channel. The air in the passenger compartment transfers heat to the external air, thereby reducing the temperature and humidity of the air in the passenger compartment. At the same time, it reduces the temperature difference between the air in the passenger compartment and the external air, which helps to improve the working effect of the passenger compartment heating and air mixing mode and improve the user experience.

[0142] In some embodiments of the present invention, such as Figures 5-7 As shown, a third air duct 61a and a fourth air duct 61b are also formed in the assembly space 51. The two ends of the third air duct 61a are connected to the air outlet 53c and the other end of the first flow channel, respectively. The two ends of the fourth air duct 61b are connected to the air outlet 53c and the other end of the second flow channel, respectively. The third air duct 61a has a movable first damper 56a, which controls the other end of the first flow channel to selectively connect to the air outlet 53c or the installation space 52. The fourth air duct 61b has a movable second damper 56b, which controls the other end of the second flow channel to selectively connect to the air outlet 53c or the installation space 52.

[0143] Furthermore, such as Figure 5 As shown, the first damper 56a is in the closed state, and the second damper 56b is in the open state, so that the other end of the first flow channel is connected to the installation space 52. This allows the air to exchange heat with the first heat exchanger 1 located in the installation space 52 as it flows sequentially along the first flow channel and the third air channel 61a, and then flows to the outlet 53c to exchange heat with the second heat exchanger 2. The other end of the second flow channel is connected to the second damper 56b, so that as the air flows sequentially along the second flow channel and the fourth air channel 61b, it flows directly to the outlet 53c to exchange heat with the second heat exchanger 2.

[0144] Furthermore, such as Figure 6 As shown, the first damper 56a is in the open state, and the second damper 56b is in the closed state, so that the other end of the second flow channel is connected to the installation space 52. This allows the air to first exchange heat with the first heat exchanger 1 located in the installation space 52, and then flow to the outlet 53c to exchange heat with the second heat exchanger 2, during the sequential flow of air along the first flow channel and the third air channel 61a. Alternatively, the other end of the first flow channel is connected to the second damper 56b, so that during the sequential flow of air along the first flow channel and the third air channel 61a, the air flows directly to the outlet 53c to exchange heat with the second heat exchanger 2.

[0145] Furthermore, such as Figure 7 As shown, both the first damper 56a and the second damper 56b are closed, so that the other end of the first flow channel and the other end of the second flow channel are connected to the installation space 52, so that the air from the first flow channel and the second flow channel first exchanges heat with the first heat exchanger 1 installed in the installation space 52, and then the air flows to the air outlet 53c to exchange heat with the second heat exchanger 2.

[0146] In some embodiments of the present invention, such as Figures 5-7 As shown, the air duct assembly 500 may further include a flow channel baffle 57. Further, as... Figure 5 andFigure 6 As shown, the flow channel baffle 57 is disposed within the assembly space 51 and is fixedly connected to the fourth heat exchanger 55, and, as Figure 5 As shown, when the second damper 56b is in the open state, one end of the second damper 56b is fixedly connected to one end of the flow channel baffle 57, thereby achieving the effect of separating the third air duct 61a and the fourth air duct 61b, as shown. Figure 6 As shown, when the first damper 56a is in the open state, one end of the first damper 56a is fixedly connected to the other end of the flow channel baffle 57, thereby achieving the effect of separating the third flow channel 61a and the fourth flow channel 61b. Thus, by setting the flow channel baffle 57 in the assembly space 51, the effect of separating the third flow channel 61a and the fourth flow channel 61b is achieved when the first damper 56a or the second damper 56b is connected to the flow channel baffle 57.

[0147] In some embodiments of the present invention, such as Figures 5-7 As shown, both the first air duct 54a and the second air duct 54b are equipped with air supply components 58. Further, the air supply component 58 can be constructed as a fan. The air supply component 58 can be located on the side of the first air duct 54a near the first air inlet 53a, and the air supply component 58 can be located on the side of the second air duct 54b near the second air inlet 53b. When the air supply component 58 is working, it drives the air to flow, thereby achieving the effect of air flowing along the first air duct 54a and / or the second air duct 54b respectively. Furthermore, when the air conditioning system 1000 is in one of the following modes: passenger compartment cooling mixed air mode, passenger compartment heating mixed air mode, and passenger compartment dehumidification mixed air mode, both the first air inlet 53a and the second air inlet 53b are open. When both the air supply component 58 located in the first air duct 54a and the air supply component 58 located in the second air duct 54b are working, the outside air of the vehicle can flow into the assembly space 51 from the first air inlet 53a along the first air duct 54a, so that the outside air of the vehicle can selectively exchange heat with the first heat exchanger 1 and / or the second heat exchanger 2. The air inside the passenger compartment of the vehicle flows into the assembly space 51 from the second air inlet 53b along the second air duct 54b, so that the air inside the passenger compartment of the vehicle can selectively exchange heat with the first heat exchanger 1 and / or the second heat exchanger 2.

[0148] In some embodiments of the present invention, such as Figures 5-7 As shown, the duct assembly 500 may further include a first opening / closing door 59a and a second opening / closing door 59b, both of which can be selectively opened or closed. Further, as... Figure 5As shown, a first opening / closing door 59a is located at a first air inlet 53a, and a second opening / closing door 59b is located at a second air inlet 53b. This allows both the first and second air inlets 53a and 53b to be selectively opened or closed. When the first opening / closing door 59a is open, it allows outside air from the vehicle to flow into the assembly space 51 through the first air inlet 53a. When the first opening / closing door 59a is closed, it prevents outside air from flowing into the assembly space 51 through the first air inlet 53a. When the second opening / closing door 59b is open, it allows air from the vehicle's passenger compartment to flow into the assembly space 51 through the second air inlet 53b. When the second opening / closing door 59b is closed, it prevents air from the vehicle's passenger compartment from flowing into the assembly space 51 through the second air inlet 53b.

[0149] Therefore, by setting the first opening and closing door 59a and the second opening and closing door 59b, the effect of selectively allowing external air to flow into the assembly space 51 and selectively allowing internal air to flow into the assembly space 51 is achieved, which in turn facilitates the implementation of the following modes: external air circulation mode for the passenger compartment, internal air circulation mode for the passenger compartment, external air circulation mode for the passenger compartment, external air circulation mode for the passenger compartment, external air circulation mode for the passenger compartment, and internal air circulation mode for the passenger compartment.
