[0002] A heat pump air conditioning system is an air conditioning system that uses the principle of heat pumps to extract and transfer heat energy from the air.

This arrangement presents problems such as inconvenient management, significant space occupation in the engine compartment, and long piping. Specifically, the distributed components increase the complexity and maintenance difficulty of the air conditioning system, while the longer piping also increases energy loss during refrigerant flow, reducing the overall efficiency of the air conditioning system.

Features specified with "first" or "second" may explicitly or implicitly include at least one of the specified features.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0049] It should be noted that the first direction L1, the second direction H, and the third direction L2 in the embodiments of this application can be referenced. Figures 2-8 Example of the coordinate system in the center direction.

[0050] It should be noted that the integrated valve island assembly in this application embodiment has an island-shaped structure that integrates multiple valves, which can control the flow direction of refrigerant (such as refrigerant).

[0051] As mentioned above, the inventive concept of this application is to provide an air conditioning refrigerant integrated module 10. Through the structural design of the air conditioning refrigerant integrated module 10, the air conditioning refrigerant components such as the gas-liquid separator 101, heat exchanger 102, compressor 105 and integrated valve island, which are dispersed in various parts of the car 1's engine compartment in the conventional technology, are integrated into one module. This reduces the space occupied by the air conditioning system 1000 in the engine compartment and reduces the length of the refrigerant transmission pipes between the components. As a result, the efficiency and reliability of the air conditioning system 1000 are improved while reducing space occupation and maintenance difficulty.

[0052] Based on the above overall concept, and referring to Figures 1-11As shown, this application embodiment provides an air conditioning refrigerant integrated module 10 including a gas-liquid separator 101, a heat exchanger 102, a bracket assembly 104, a compressor 105, and an integrated valve island assembly 108; the integrated valve island assembly 108 and the compressor 105 are arranged at a distance along a first direction L1; the bracket assembly 104 is arranged along the first direction L1 between the integrated valve island assembly 108 and the compressor 105, and is connected to both the integrated valve island assembly 108 and the compressor 105 respectively, and the bracket assembly 104 is used to fix and connect the vehicle structure; the heat exchanger 102 and the integrated valve island assembly 108... The gas-liquid separator 101 and the heat exchanger 102 are connected along the third direction L2 and connected to the integrated valve island assembly 108. The compressor 105 is connected to the gas-liquid separator 101 and the integrated valve island assembly 108 respectively, so as to compress the refrigerant delivered by the gas-liquid separator 101 and deliver it to the integrated valve island assembly 108. The integrated valve island assembly 108 is equipped with multiple valves and pipe interfaces. The integrated valve island assembly 108 is configured to switch the opening and closing state of each valve so that the refrigerant flows through the corresponding pipe interface according to the predetermined flow path.

[0053] Understandable, for reference Figure 2 As shown, the air conditioning refrigerant integrated module 10 mainly consists of five sub-components: gas-liquid separator 101 (GLS), heat exchanger 102 (CHILLER), bracket assembly 104, compressor 105 (EAC), and integrated valve island assembly 108 (VALVE). The bracket assembly 104 connects the compressor 105 and the integrated valve island assembly 108 at both ends along the first direction L1, respectively. The bracket assembly 104 can fix the air conditioning refrigerant integrated module 10 as a whole on the vehicle structure 20, thereby simplifying and reducing the number of installation and mating points between the air conditioning components and the vehicle structure.

[0054] The heat exchanger 102 is mainly used for heat exchange. The heat exchanger 102 is connected and communicates with the integrated valve island assembly 108 along the second direction H. That is, the heat exchanger 102 is located at the bottom of the integrated valve island assembly 108 so that the refrigerant can flow between the integrated valve island assembly 108 and the heat exchanger 102. The gas-liquid separator 101 is connected to the heat exchanger 102 along the third direction L2 and is connected and communicates with the integrated valve island assembly 108. The compressor 105 is connected to the gas-liquid separator 101 and the integrated valve island assembly 108 respectively. The refrigerant can flow between the integrated valve island assembly 108, the gas-liquid separator 101 and the compressor 105. The gas-liquid separator 101 can separate the gas and liquid in the refrigerant to ensure that the refrigerant introduced into the compressor 105 is in the target state. The compressor 105 can be responsible for compressing the refrigerant, increasing its pressure and temperature, and driving the refrigeration cycle. The integrated valve island assembly 108 integrates multiple pipe interfaces and valves. These multiple pipe interfaces can be connected to the refrigerant inlet and outlet of different external heat exchange components. The multiple pipe interfaces can be interconnected or blocked based on the opening or closing of the corresponding valves. This allows for switching the opening and closing states of each valve as needed, controlling the refrigerant to flow through specific pipe interfaces along a predetermined path to achieve different air conditioning functions.

[0055] As a result of this design, the air conditioning refrigerant integration module 10 optimizes space utilization, reduces the length of refrigerant transmission pipes, improves the efficiency and reliability of the air conditioning system 1000, and also reduces maintenance difficulty by integrating key components.

[0057] The valve island 301 integrates multiple valves, including an electronic expansion valve (EXV), a check valve (CV), and a shut-off valve (SOV), as well as multiple interconnected pipe interfaces to control the flow direction and flow rate of the refrigerant. The valve island base plate 302 is a plate-shaped piece connected to the bottom of the valve island 301 along the second direction H.

The top of the heat exchanger interface 302A is connected to the valve island 301, and the bottom of the heat exchanger interface 302A is connected to the heat exchanger 102, so that the refrigerant can flow between the valve island 301 and the heat exchanger 102 through the heat exchanger interface 302A on the valve island base plate 302.

The two first pipe interfaces are respectively inserted into and connected to the heat exchanger interfaces 302A on the valve island base plate 302. A first fastener 107 passes through the valve island base plate 302 from top to bottom along a second direction H and is fastened into the corresponding connection hole, thereby achieving the fixation and connection between the heat exchanger body 102A and the valve island 301. The first connecting bracket 102B and the second connecting bracket 102C are respectively connected to the two ends of the heat exchanger body 102A along the third direction L2. The first connecting bracket 102B is adapted to the contour of the gas-liquid separator 101, so that the gas-liquid separator 101 can be installed on the first connecting bracket 102B and fastened by bolts. The second connecting bracket 102B is connected to the bottom of the valve island base plate 302 along the third direction L2 by the second fastener 110, which further ensures the connection stability between the heat exchanger 102 and the integrated valve island assembly 108.

[0062] In this embodiment, the valve island 301 is mainly composed of a first mounting part R1, a second mounting part R2, and a third mounting part R3.

The first mounting part R1 and the second mounting part R2 are arranged at intervals along the third direction L2. The third mounting part R3 is connected along the first direction L1 to the same end of the first mounting part R1 and the second mounting part R2 away from the bracket assembly 104. The pipes in the third mounting part R3 are interconnected with those in the first mounting part R1 and the second mounting part R2 to provide a flexible pipe connection method, which facilitates the control and distribution of refrigerant flow.

[0066] In addition, the third mounting part R3 is provided with multiple third pipe interfaces at the end away from the first mounting part R1 and the second mounting part R2. The top of the third pipe interface is provided with a sixth interface 301F, a seventh interface 301G and an eighth interface 301H arranged sequentially at intervals along the third direction L2.

The bottom of the third shut-off valve 314 is also provided with a first one-way valve 316. After the first one-way valve 316 is placed in the eighth interface 301H, the third shut-off valve 314 seals the eighth interface 301H, so that the refrigerant flows unidirectionally to the gas-liquid separator 101.

[0067] In some embodiments, the bottom of the first mounting part R1 and the second mounting part R2 are respectively provided with a ninth interface (not shown), which is used to connect to the heat exchanger interface 302A; the top of the first mounting part R1 is also provided with two tenth interfaces 301I, and the first temperature sensor 315 and the second temperature sensor 317 are respectively provided in the two tenth interfaces; the top of the third mounting part R3 adjacent to the second mounting part R2 is also provided with an eleventh interface 301J, and the eleventh interface 301J is provided with a temperature and pressure sensor 310.

[0068] It should be noted that the temperature and pressure sensor 310 is an integrated pressure / temperature sensor that can detect the temperature and pressure data of the refrigerant flowing through it.

[0069] The first mounting section R1 and the bottom of the second mounting section R2 are provided with a ninth interface, which can be connected to the heat exchanger interface 302A of the valve island base plate 302, so as to directly connect the valve island 301 and the heat exchanger 102, optimize the refrigerant flow direction, and improve the heat exchange efficiency. The top of the first mounting section R1 is also provided with two tenth interfaces 301I. The two tenth interfaces 301I are arranged at intervals along the third direction and are connected to the pipes in the third mounting section R3. The two tenth interfaces 301I are respectively provided with a first temperature sensor 315 and a second temperature sensor 317. The first temperature sensor 315 and the second temperature sensor 317 can monitor the temperature changes in the valve island 301, so as to adjust the refrigerant flow and compressor working status in a timely manner and achieve more precise temperature control. The top of the third mounting section R3 adjacent to the second mounting section R2 is also provided with an eleventh interface 301J. The temperature and pressure sensor 310 provided in the eleventh interface 301J can detect the pressure and temperature data of the refrigerant flowing through it, so as to control the compression, expansion and flow of the refrigerant more precisely and optimize the air conditioning performance.

[0070] Thus, the design of valve island 301, by integrating various valves, pipe interfaces and sensors, achieves precise control of refrigerant flow, improves the efficiency, safety, reliability and intelligence of the air conditioning system, and also enhances the versatility and integration of the air conditioning refrigerant integration module 10.

[0071] It should be understood that in valve island 301, except for the check valve, the other electronic expansion valves and shut-off valves are partially installed in their respective interfaces.

[0073] In this embodiment, the bracket assembly 104 includes a bracket body 201, a first extension bracket 202, and a second extension bracket 204. The bracket body 201 is plate-shaped. The first extension bracket 202 and the second extension bracket 204 are spaced apart on the bracket body 201 along a third direction. Based on the bracket body 201 extending towards the valve island 301, the ends of the first extension bracket 202 and the second extension bracket 204 facing the valve island 301 are each provided with a rubber sleeve for vibration damping.

When the compressor 105 is connected to the bracket body 201, the two connecting parts 106 pass through the through holes in the center of the second compressor vibration damping pad 207 and the third compressor vibration damping pad 209 from the side of the bracket body 201 away from the compressor 105 and are screwed to the corresponding mounting parts. One connecting part 106 passes through the through hole of the mounting part from the side of the compressor 105 away from the bracket body 201, passes through the first compressor vibration damping pad 203 on the bracket body 201, and is then connected to the mating part 103, which can be a nut, thereby achieving a stable connection between the compressor 105 and the bracket body 201.

[0075] In addition, the first frame connection hole 208 and the second frame connection hole 206, which are opened on the top of the bracket body 201, are arranged at intervals along the third direction L3, so as to allow bolts to be fixedly connected to the vehicle structure 20 along the first direction H (reference).

In addition, a pressure sensor 101A is also provided on the gas-liquid separator 101 to monitor the pressure of the gas-liquid separator 101.

[0080] By configuring the air conditioning refrigerant integration module 10 of this application embodiment within the air conditioning system 1000, the integrated valve island assembly 108 controls the opening and closing of various valves within the valve island 301 to connect or disconnect the circuit, allowing the refrigerant to flow along a predetermined flow path. This enables seven functional modes: 1. Passenger compartment cooling; 2. Passenger compartment cooling and battery cooling; 3. Passenger compartment heating and dehumidification; 4. Outdoor heat exchanger defrosting; 5. Passenger compartment heating and battery cooling; 6. Heat pump and battery cooling; 7. Passenger compartment heat pump heating.
