Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a valve island and an air conditioner having a valve island. Background Technology

[0002] In air conditioning systems, most conventional piping uses copper pipes, while a small portion uses steel pipes to connect various components. The design of piping needs to consider the clearance requirements between pipes, so the space occupied by piping accounts for a large proportion of the system enclosure, and the cost of copper materials also contributes significantly.

[0003] In related technologies, to solve the problems of large space occupation and high material cost of piping, valve islands are set up to integrate the pipeline and replace the piping. The main processing method of the integrated valve island in this technical solution is to first process two independent metal structures. The upper part mainly processes the various structures and internal flow channels, while the lower part has no flow channels. The two parts are welded to form a complete valve island structure. The refrigerant enters and exits the valve island through various interfaces and is interconnected through flow channels.

[0004] However, in this technical solution, the welding surfaces of the upper and lower parts are relatively large, and the upper and lower structures are welded by surface bonding, which requires a high degree of flatness of the bonding surface. The welding quality of this processing method is also affected by the deformation of the two structural components. If the upper and lower structural components are deformed before welding, or if the deformation of the upper and lower structures is inconsistent during welding, it will lead to incomplete welding or other welding failures, which will seriously affect the reliability of the valve island components.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following is for reference. Figures 5-16 The valve island 10 according to a first aspect embodiment of the present invention is described.

[0030] like Figure 5 and Figure 6 As shown, the valve island 10 according to the first aspect of the present invention includes: a valve island body 11 and a sealing member 12.

[0031] Specifically, the valve island body 11 is integrally formed, and the valve island body 11 has multiple flow channels 112 and multiple valve island interfaces 111. Each flow channel 112 is connected to at least two valve island interfaces 111. The valve island body 11 also has flow channel machining holes 113 that are connected to the flow channels 112. The sealing member 12 is provided at the position of the flow channel machining hole 113 to seal the flow channel machining hole 113.

[0032] In this embodiment, the valve island body 11 is a one-piece molded part, rather than being assembled from multiple separately processed parts. In other words, the flow channel 112 and the valve island interface 111 within the valve island body 11 are both defined by the valve island body 11 itself, and the flow channel processing hole 113 on the valve island body 11 is a process hole for processing the flow channel 112.

[0033] For example, the flow channel 112 and the valve island interface 111 can both be directly formed by the valve island body 11 during the casting process. The flow channel machining hole 113 can be a core-pulling hole during casting. Alternatively, the flow channel 112 and the valve island interface 111 can be machined on the raw material of the valve island body 11 by machining. The flow channel machining hole 113 is a hole machined on the raw material of the valve island body 11 before machining the flow channel 112. Then, the machining tool extends into the valve island body 11 through the flow channel machining hole 113 to machine the flow channel 112.

[0034] In some examples, the number of flow channels 112 can be two, three, four, five, six, eight, ten, or more. The number of valve island interfaces 111 can be four, eight, ten, fifteen, twenty, or more. A flow channel 112 can connect to two valve island interfaces 111, or it can connect to three or four valve island interfaces 111. Furthermore, among the multiple flow channels 112, only a portion of the flow channels 112 may have flow channel machining holes 113, or all flow channels 112 may have flow channel machining holes 113. Furthermore, a flow channel 112 may have one flow channel machining hole 113, or it may have multiple flow channel machining holes 113.

[0035] The sealing element 12 is used to seal the machined hole 113 of the flow channel 112 after the flow channel 112 has been machined. The sealing element 12 is sealed to the valve island body 11 to prevent refrigerant leakage in the flow channel 112. For example, the sealing element 12 and the valve island body 11 can be connected by flange fasteners or by welding, as long as a seal between the sealing element 12 and the valve island body 11 can be achieved.

[0036] This embodiment sets the valve island body 11 as a single piece, and forms the valve island interface 111 and flow channel 112 by the valve island body 11 itself. This not only reduces the number of parts and improves assembly efficiency, but also avoids the occurrence of false welding or welding failure due to inconsistent deformation, thus improving the finished product quality of the valve island body 11 and ensuring the reliability and sealing of the valve island 10.

[0037] This embodiment, by providing a flow channel machining hole 113, facilitates the machining of the flow channel 112 within the valve island body 11, improving machining efficiency, ensuring machining accuracy, and further enhancing the finished product quality of the valve island body 11. Simultaneously, this embodiment, by providing a sealing component 12 to seal the flow channel machining hole 113, ensures the integrity of the flow channel 112, prevents refrigerant leakage at the flow channel machining hole 113 location, ensures the refrigerant within the flow channel 112 flows along a preset path, and guarantees the stable operation of the air conditioner 100.

[0038] According to the embodiment of the present utility model, the valve island 10 is configured as a single piece, and a flow channel 112, a valve island interface 111 communicating with the flow channel 112, and a flow channel processing hole 113 are formed on the valve island body 11. Then, the flow channel processing hole 113 is blocked by a sealing member 12. Thus, it is not only convenient to process and form the flow channel 112, ensuring the smooth processing of the internal flow channel 112, but also ensuring the sealing performance of the valve island 10. This makes the flow guiding effect and reliability of the valve island 10 better, and improves the finished product quality and yield of the valve island 10.

[0039] In some embodiments of this utility model, reference is made to Figures 10-13 As shown, the sealing element 12 is welded to the valve island body 11. This embodiment, by welding the valve island body 11 to the sealing element 12, forms a high-strength sealing structure at the connection point, preventing refrigerant leakage from the flow channel 112 through the flow channel machining hole 113, thus improving the sealing performance of the valve island 10. Furthermore, the welded connection improves the pressure-bearing and vibration-resistant properties at the connection point between the valve island body 11 and the sealing element 12, ensuring the stability and reliability of the valve island 10's operation.

[0040] In some embodiments of this utility model, reference is made to Figures 12-13 As shown, in the direction from the flow channel machining hole 113 toward the flow channel 112 that communicates with the flow channel machining hole 113, the cross-sectional area of ​​the flow channel machining hole 113 decreases. That is, the cross-sectional area of ​​the end of the flow channel machining hole 113 that is connected to the flow channel 112 is smaller than the cross-sectional area of ​​the end of the flow channel machining hole 113 that is away from the flow channel 112.

[0041] The cross-sectional area of ​​the flow channel machining hole 113 can be gradually reduced, and the cross-sectional area of ​​the flow channel machining hole 113 can also be reduced in a stepwise manner. In this way, the flow channel machining hole 113 can guide the tool or mold for machining the flow channel 112. On the other hand, when the sealing member 12 is fitted into the flow channel machining hole 113, it can increase the contact area between the sealing member 12 and the valve island body 11, increase the sealing area between the sealing member 12 and the valve island body 11, and thus improve the sealing performance at the connection position between the sealing member 12 and the valve island body 11.

[0042] In some embodiments of this utility model, reference is made to Figures 12-13As shown, the flow channel machining hole 113 includes a first hole section 1131 and a second hole section 1132. The first hole section 1131 penetrates the outer surface of the valve island body 11, and the second hole section 1132 connects the first hole section 1131 and the flow channel 112. The cross-sectional area of ​​the first hole section 1131 is larger than the cross-sectional area of ​​the second hole section 1132. A stepped surface 1133 is formed at the connection position of the first hole section 1131 and the second hole section 1132. The sealing member 12 has a first sealing part 121. The first sealing part 121 is disposed in the first hole section 1131, and the side surface of the first sealing part 121 facing the second hole section 1132 is in contact with the stepped surface 1133.

[0043] In this embodiment, a stepped surface 1133 is formed at the connection position of the first hole segment 1131 and the second hole segment 1132. The first sealing part 121 abuts against the stepped surface 1133. In this way, the stepped surface 1133 can accurately position the first sealing part 121, realize the positioning of the sealing part 12, improve the assembly efficiency between the sealing part 12 and the valve island body 11. At the same time, the sealing part 12 fits against the inner wall of the flow channel processing hole 113 at the step surface 1133 position, which can enhance the pressure bearing capacity at the connection position between the sealing part 12 and the valve island body 11, and further reduce the risk of refrigerant leakage from the flow channel processing hole 113 position.

[0044] Furthermore, the first hole segment 1131 has a circular cross-section and is a constant-diameter segment. The second hole segment 1132 also has a circular cross-section and is a constant-diameter segment. This simplifies the structure of the flow channel machining hole 113, facilitates the machining of the first hole segment 1131 and the second hole segment 1132, and reduces the risk of stress concentration at the location of the flow channel machining hole 113.

[0045] In some embodiments of this utility model, reference is made to Figures 12-13 As shown, in the direction from the center of the first hole segment 1131 toward the periphery, the minimum width of the step surface 1133 is greater than or equal to 2 mm. For example, the minimum width of the step surface 1133 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, etc.

[0046] This embodiment ensures that the minimum width of the stepped surface 1133 is greater than or equal to 2mm, thereby guaranteeing the effective contact area between the stepped surface 1133 and the first sealing part 121, enhancing the sealing reliability between the sealing part 12 and the valve island body 11, improving the structural strength of the stepped surface 1133, reducing the risk of deformation of the stepped surface 1133 and the first sealing part 121 under refrigerant pressure, reducing the risk of sealing failure caused by stress concentration, and ensuring that the valve island 10 can operate stably for a long time.

[0047] In some embodiments of this utility model, reference is made to Figures 12-13As shown, in the depth direction of the flow channel machining hole 113 (e.g.) Figure 12 In the left-right direction shown, the depth of the first hole segment 1131 is greater than or equal to 1 mm, and the thickness of the first sealing part 121 is greater than or equal to 1 mm. For example, the depth of the first hole segment 1131 can be 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, or 4 mm, etc. The thickness of the first sealing part 121 can be 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.3 mm, 2.5 mm, 2.8 mm, 3 mm, 3.5 mm, or 4 mm, etc.

[0048] In this embodiment, by ensuring that the depth of the first hole segment 1131 is greater than or equal to 1 mm, the first hole segment 1131 provides sufficient installation space for the sealing member 12, ensuring that the first sealing part 121 can be stably and reliably embedded within the first hole segment 1131. Simultaneously, the thickness of the first sealing part 121 is greater than or equal to 1 mm, which enhances the structural strength of the first sealing part 121 and reduces the risk of local deformation. Furthermore, the fact that both the depth of the first hole segment 1131 and the thickness of the first sealing part 121 are greater than 1 mm improves the pressure-bearing performance of the sealing surface between the sealing member 12 and the inner wall of the flow channel machining hole 113, further reducing the risk of leakage.

[0049] In some examples, the thickness of the first sealing part 121 is greater than or equal to the depth of the first hole segment 1131. In this way, the first sealing part 121 can be flush with the periphery of the flow channel processing hole 113, or protrude from the periphery of the flow channel processing hole 113. As a result, the inner wall of the first hole segment 1131 can be completely fitted and sealed with the first sealing part 121, improving the sealing performance. At the same time, it can also facilitate the welding connection between the sealing part 12 and the outer peripheral surface of the valve island 10, improving the welding reliability.

[0050] In some embodiments of this utility model, reference is made to Figures 12-13 As shown, the sealing component 12 also includes a second sealing portion 122, which is connected to the first sealing portion 121. The second sealing portion 122 is disposed within the second hole section 1132 and is adapted to the shape of the second hole section 1132. In this embodiment, by fitting the second sealing portion 122 into the second hole section 1132, a double sealing structure can be formed between the sealing component 12 and the inner wall of the flow channel machining hole 113, improving the overall sealing performance. The second sealing portion 122 can also enhance the connection stability between the sealing component 12 and the flow channel machining hole 113, preventing the sealing component 12 from shaking, reducing the risk of sealing failure, and ensuring the long-term reliable operation of the valve island 10.

[0051] In some embodiments of this utility model, reference is made to Figure 7 , Figure 8 and Figure 16 As shown, in the direction from the flow channel machining hole 113 toward the flow channel 112 communicating with the flow channel machining hole 113, at least a portion of the flow channel machining hole 113 is formed as an inclined section, the inner peripheral surface of the inclined section extends obliquely toward the central axis of the flow channel machining hole 113, and at least a portion of the outer peripheral surface of the sealing member 12 is formed as a mating inclined surface adapted to the shape of the inclined section.

[0052] For example, in the direction from the flow channel machining hole 113 toward the flow channel 112 that communicates with the flow channel machining hole 113, the flow channel machining hole 113 may be formed as an inclined section in only a part or in all of the form. When the flow channel machining hole 113 is formed as an inclined section in all of the form, the cross-sectional size of the flow channel machining hole 113 gradually decreases.

[0053] In this embodiment, by mates the inclined section of the flow channel machining hole 113 with the mating inclined surface of the sealing member 12, the inner wall of the flow channel machining hole 113 and the outer peripheral surface of the sealing member 12 can form a conical sealing structure, making the sealing member 12 fit more tightly with the inner wall of the flow channel machining hole 113, reducing the risk of radial shaking of the sealing member 12, and also increasing the sealing contact area, further improving the sealing performance of the valve island 10.

[0054] In some embodiments of this utility model, an internal thread is formed on the inner wall surface of the flow channel machining hole 113, and the sealing member 12 has an external thread adapted to the internal thread. The sealing member 12 is threadedly fitted into the flow channel machining hole 113. This facilitates the installation and disassembly of the sealing member 12 and the valve island body 11, facilitates the maintenance and replacement of the sealing member 12, and improves assembly efficiency.

[0055] Furthermore, the valve island 10 also includes a sealing ring, which is fitted onto the plugging member 12 and seals against the inner wall of the plugging member 12 and the flow channel machining hole 113. This further improves the sealing performance at the connection between the plugging member 12 and the valve island body 11.

[0056] In some embodiments of this utility model, reference is made to Figure 5 , Figure 7 and Figure 11 As shown, a portion of the multiple flow channels 112 is a connecting channel, which extends in a straight line in a plane perpendicular to the first direction. The openings of the multiple valve island interfaces 111 connected to the connecting channel all face the first direction (e.g., Figure 5 (as shown in the up-down direction), the flow channel processing hole 113 is formed at at least one end of the connecting channel in the extension direction, and the flow channel processing hole 113 penetrates the outer surface of the valve island body 11 along the extension direction of the connecting channel connected to the flow channel processing hole 113.

[0057] In other words, the extension direction of the connecting channel is perpendicular to the opening direction of the valve island interface 111 connected to the connecting channel. Therefore, during the processing of the connecting channel, it is not possible to insert the connecting channel into the valve island body 11 from the position of the valve island interface 111 to process and shape the connecting channel. At this time, in order to facilitate the processing and shaping of the connecting channel, flow channel processing holes 113 are processed at one or both ends of the connecting channel. The mold or tool is inserted into the valve island body 11 from the position of the flow channel processing hole 113 to process and shape the connecting channel.

[0058] In this embodiment, by forming the flow channel processing hole 113 at one or both ends of the connecting channel, the connecting channel can be easily processed and shaped, simplifying the structure of the valve island body 11 and improving processing efficiency.

[0059] In some embodiments of this utility model, such as Figure 5 As shown, there are multiple connecting channels and multiple flow channel machining holes 113, with each flow channel machining hole 113 corresponding to one of the multiple connecting channels. This allows for easier machining of the connecting channels while reducing the number of flow channel machining holes 113, thus reducing the number of components in the valve island 10, improving assembly efficiency, and lowering the risk of leakage in the valve island 10.

[0060] In some embodiments of this utility model, such as Figure 5 As shown, the first direction is the thickness direction of the valve island body 11 (e.g., Figure 5 and Figure 7 As shown in the vertical direction), the openings of the multiple valve island interfaces 111 connected to the connecting channel face one or both sides of the valve island body 11 in the thickness direction. The flow channel processing hole 113 extends perpendicular to the thickness direction of the valve island body 11 and penetrates the outer peripheral surface of the valve island body 11.

[0061] In this embodiment, by having the openings of the multiple valve island interfaces 111 connected to the communication channel facing both sides of the valve island body 11 in the thickness direction, it is possible to facilitate the connection of other functional components of the air conditioner 100 to the valve island 10, thereby making the structure of the air conditioner 100 more compact and improving space utilization.

[0062] In some embodiments of this utility model, such as Figure 5 As shown, another portion of the plurality of flow channels 112 is formed as a fluid channel, which extends in a straight line. At least one of the plurality of valve island interfaces 111 connected to the fluid channel has its opening facing the same direction as the extension of the fluid channel. Thus, during the machining of the valve island body 11, the fluid channel can be directly machined through the valve island interface 111 facing the same direction as the extension of the fluid channel, without the need for additional flow channel machining holes 113. This further simplifies the structure of the valve island body 11 and ensures the sealing performance of the valve island 10.

[0063] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the valve island body 11 includes multiple island sections 114, multiple flow channels 112, multiple valve island interfaces 111, and multiple flow channel machining holes 113, all formed on the multiple island sections 114. Adjacent island sections 114 are directly connected or connected by connecting ribs 115. Each island section 114 has one or more flow channels 112 arranged at intervals. In other words, one island section 114 is a flow channel 112 arrangement area of ​​the valve island body 11. Thus, the valve island body 11 can reduce the connection structure between island sections 114, reduce the material usage of the valve island body 11, and reduce costs, while meeting the requirements of forming multiple flow channels 112 and the structural strength of the valve island body 11. In addition, it can also reduce heat transfer between the flow channels 112 of adjacent island sections 114, thereby reducing the mutual influence between the flow channels 112.

[0064] In some embodiments of this utility model, at least a portion of the valve island body 11 is made of stainless steel. That is, the valve island body 11 can be partially made of stainless steel, or the entire valve island body 11 can be made of stainless steel. For example, at least a portion of the island portion 114 of the valve island body 11 can be made of stainless steel, and / or at least a portion of the connecting ribs 115 of the valve island body 11 can be made of stainless steel. By making at least a portion of the valve island body 11 made of stainless steel, this embodiment can improve the strength and corrosion resistance of the valve island body 11, enhance its impact resistance and fatigue resistance, thereby increasing the service life of the valve island body 11 and the valve island.

[0065] In some embodiments of this utility model, the material of the valve island body 11 is the same as or different from the material of the sealing element 12. When the material of the valve island body 11 and the sealing element 12 is the same, the performance parameters of the valve island body 11 and the sealing element 12 can be consistent. For example, the coefficients of thermal expansion of the valve island body 11 and the sealing element 12 can be consistent. This avoids the valve island body 11 and the sealing element from deforming to different degrees under the action of temperature difference, which could lead to sealing failure or deformation and cracking at the connection position of the valve island body 11 and the sealing element 12. When the materials of the valve island body 11 and the sealing element 12 are different, appropriate materials can be selected according to the different requirements of the valve island body 11 and the sealing element 12, thereby reducing costs while optimizing the valve island performance. For example, the valve island body 11 can be made of a corrosion-resistant and high-strength material, and the sealing element 12 can be made of a material with a certain degree of elasticity to improve the sealing performance between the sealing element 12 and the valve island body 11.

[0066] In some examples, the valve island body 11 can be made of aluminum alloy, copper alloy or stainless steel. If the valve island body 11 is made of aluminum alloy, the weight of the valve island body 11 can be reduced, achieving lightweighting; if the valve island body 11 is made of copper alloy, the corrosion resistance and sealing performance of the valve island body 11 can be improved; if the valve island body 11 is made of stainless steel, the corrosion resistance and service life can be improved.

[0067] In some examples, the sealing element 12 can be made of aluminum alloy, copper alloy, or stainless steel. Making the sealing element 12 of aluminum alloy reduces weight and achieves lightweight construction; making it of copper alloy or stainless steel improves its corrosion resistance and extends its service life.

[0088] In this embodiment, the valve island 10 consists of a valve island body 11 and a sealing component 12. The valve island body 11 has an internal flow channel 112 and an external valve island interface 111 for connecting to the functional components of the air conditioner 100. The functional components are connected through the flow channel 112 within the valve island body 11, enabling the normal operation of the air conditioner 100. This allows for the integration of the piping system, reducing the internal space occupied by the piping system, reducing the use of various accessories (damping rubber, rubber gaskets, cable ties, etc.), shortening the piping material, and lowering costs.

[0089] Furthermore, in this embodiment, the valve island 10 adopts a structure of valve island body 11 plus sealing component 12, which can ensure the smooth processing of the internal flow channel 112 and at the same time ensure the sealing performance of valve island 10, making the flow guiding effect and reliability of valve island 10 better. In addition, since the valve island body 11 is processed as a whole, compared with the method of segmented welding, the valve island body 11 in this embodiment has better structural strength, which can avoid problems such as false welding caused by the flatness of the welding surface and deformation in the segmented welding of valve island body 11, thus improving the production yield of valve island 10.

[0090] Furthermore, in this embodiment, stepped surfaces 1133 are provided at the locations of multiple flow channel machining holes 113 of the valve island body 11, and the contact width between the sealing member 12 and the stepped surface 1133 must be greater than or equal to 2mm, thereby ensuring the welding strength between the sealing member 12 and the valve island body 11. Simultaneously, the provision of sealing members 12 at the locations of multiple flow channel machining holes 113 ensures the sealing performance of the flow channel 112. It should be noted that the diameter of the multiple sealing members 12 is determined by the diameter of the flow channel machining hole 113 it is sealing. The diameter of the sealing member 12 needs to be greater than the maximum diameter of the flow channel machining hole 113, thus ensuring that the sealing member 12 can completely block the corresponding flow channel machining hole 113 while meeting the design requirements of the flow channel 112.

[0091] Meanwhile, the valve island body 11 is composed of multiple islands 114, which allows for the retention of only the flow channel 112 structure while meeting structural strength requirements. This reduces the weight and cost of materials used, as well as the heat transfer between the flow channels 112, thus minimizing the impact on the performance of the air conditioner 100.

[0092] The valve island 10 in the above embodiment can eliminate the upper and lower plane welding method while ensuring the same integration and flow channel 112 settings, thereby improving the welding quality of the valve island 10 and the reliability of the formed valve island 10; it can ensure the structural strength of the valve island 10 and avoid local damage caused by the welding process.

[0093] Furthermore, when assembling the valve island 10 with multiple functional components, the filter 60 (flange and filter screen) can be pre-installed on the corresponding valve island interface 111 of the valve island body 11. In addition, when connecting valve structures such as the electronic expansion valve 23 and piping structures such as the connecting pipe 22 to the multiple valve island interfaces 111 of the valve island 10, they can be welded sequentially from the center of the valve island 10 outwards. During the assembly process, various valve structures are cooled during welding to avoid high temperatures.

[0094] The following describes the refrigerant's operating path in the air conditioner 100 during heating mode in this embodiment.

[0095] like Figure 17As shown, after the compressor 30 discharges, the refrigerant enters the four-way valve 24 through piping, then sequentially enters the first port 111k of the four-way valve, the first fluid channel, and the low-pressure valve port 111d, before entering the low-pressure shut-off valve 251 and finally the indoor heat exchanger. After exchanging heat with the environment in the indoor heat exchanger, the refrigerant passes through the high-pressure shut-off valve 252, then sequentially passes through the high-pressure valve port 111h connected to the high-pressure valve, the second fluid channel, and the first port 111q of the plate heat exchanger main circuit. After passing through the heat exchange main circuit of the plate heat exchanger 21, it enters the first connecting channel through the second port 111s of the plate heat exchanger main circuit. In the first connecting channel, the refrigerant is divided into two paths: the first path enters the refrigerant heat dissipation pipe 50 through the first port 111c of the refrigerant heat dissipation pipe, and the second path enters the enthalpy-increasing branch expansion valve 251. The refrigerant enters the enthalpy-increasing branch through interface 111b. After further throttling by the electronic expansion valve 23 on the enthalpy-increasing branch, it sequentially passes through the first interface 111a of the expansion valve 21, the second connecting channel, and the second interface 111r of the plate heat exchanger enthalpy-increasing branch. The refrigerant undergoes sufficient heat exchange with the main heat exchanger in the main heat exchanger of the plate heat exchanger 21. Then, it sequentially passes through the first interface 111p of the plate heat exchanger enthalpy-increasing branch, the third fluid channel, and the enthalpy-increasing pipe interface 111i, and then enters the enthalpy-increasing port of the compressor 30 through the connecting pipe. After exiting the refrigerant heat dissipation pipe 50, the refrigerant from the first path sequentially passes through the second interface 111e of the refrigerant heat dissipation pipe, the third connecting channel, and the first interface 111f of the expansion valve, enters the electronic expansion valve 23, and then sequentially passes through the second interface 111g of the expansion valve, the fourth connecting channel, and the filter interface 111j, and enters the outdoor heat exchanger 40. After the outdoor heat exchanger 40 exchanges heat with the outdoor environment, the refrigerant passes through the first interface 111n of the outdoor heat exchanger, the fifth connecting channel and the second interface 111m of the four-way valve in sequence, then enters the four-way valve 24, and then enters the gas-liquid separator 28, where gas-liquid separation takes place, and finally enters the return gas pipe of the compressor 30 through the connecting pipe 22.
