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.

[0048] The following is combined Figures 1-14 This invention describes the heat exchanger assembly and air conditioning system of the present invention.

[0049] An embodiment of this utility model provides a heat exchanger assembly, such as... Figure 1 and Figure 2 As shown, the heat exchanger assembly includes a heat exchange module 610 and a control valve group; the heat exchange module 610 includes a first heat exchange component 611 and a second heat exchange component 612 arranged opposite to each other along a first direction, the first end of the first heat exchange component 611 and the first end of the second heat exchange component 612 are spliced ​​together, the second end of the first heat exchange component 611 and the second end of the second heat exchange component 612 form an inspection port, and the first heat exchange component 611 and the second heat exchange component 612 form an installation space.

[0050] The first heat exchange component 611 includes a first heat exchanger 6111. The number of first heat exchangers 6111 can be one or more. When the number of first heat exchangers 6111 is multiple, the multiple first heat exchangers 6111 are arranged side by side along the second direction.

[0051] The second heat exchange component 612 includes a second heat exchanger 6121. The number of second heat exchangers 6121 can be one or more. When there are multiple second heat exchangers 6121, the multiple second heat exchangers 6121 are arranged side by side along the second direction.

[0052] The control valve assembly includes a first control valve 620 and a second control valve 630. The number of first control valves 620 is equal to the number of first heat exchangers 6111, and they are connected in a one-to-one correspondence. Each first heat exchanger 6111 is connected to one first control valve 620, which controls the opening and closing of the corresponding first heat exchanger 6111 and the flow rate. The number of second control valves 630 is equal to the number of second heat exchangers 6121, and they are connected in a one-to-one correspondence. Each second heat exchanger 6121 is connected to one second control valve 630, which controls the opening and closing of the corresponding second heat exchanger 6121 and the flow rate.

[0053] It should be noted that the first direction can be horizontal, and the second direction can be vertical.

[0054] It is understood that the heat exchange module 610 includes multiple heat exchangers (first heat exchanger 6111 and second heat exchanger 6121), and each heat exchanger is independently connected to a corresponding control valve (first control valve 620 corresponds to first heat exchanger 6111, and second control valve 630 corresponds to second heat exchanger 6121). Some heat exchangers can be flexibly started and stopped according to actual heat load requirements to avoid energy waste under low load conditions. At the same time, it can also fully utilize the heat exchange capacity of all heat exchangers under high load conditions, thereby significantly improving overall energy efficiency.

[0055] The heat exchanger assembly provided in this embodiment of the utility model divides the heat exchange module 610 into two heat exchange regions, namely a first heat exchange component 611 and a second heat exchange component 612. At least one heat exchange region uses multiple heat exchangers, so the heat exchange module 610 includes multiple heat exchangers arranged in zones. Each heat exchanger is independently connected to a corresponding control valve, and the corresponding number of heat exchangers can be flexibly selected for combination and use according to different operating conditions, thereby significantly improving heat exchange efficiency.

[0056] Specifically, some heat exchangers can be flexibly started and stopped according to actual heat load requirements to avoid energy waste under low load conditions; at the same time, the heat exchange capacity of all heat exchangers can be fully utilized under high load conditions, thereby significantly improving overall energy efficiency.

[0057] It should be noted that the heat exchange module 610 adopts at least one first heat exchanger 6111 and at least one second heat exchanger 6121, thus the heat exchange module 610 adopts a segmented structure, which facilitates maintenance and partial replacement, reduces operating costs, extends the service life of the equipment, and has significant energy-saving and economic benefits.

[0058] In one embodiment of the present invention, the first heat exchange component 611 has an L-shaped cross-section and includes a first heat exchanger 6111.

[0059] Optionally, the cross-section of the second heat exchange component 612 is U-shaped, and the second heat exchange component 612 includes two second heat exchangers 6121.

[0060] In this embodiment, the first heat exchange component 611 is L-shaped, so the first heat exchanger 6111 is an L-shaped heat exchanger, and the first heat exchange component 611 includes one L-shaped heat exchanger; the second heat exchange component 612 is U-shaped, so the second heat exchanger 6121 is a U-shaped heat exchanger, and the second heat exchange component 612 includes two U-shaped heat exchangers arranged vertically; thus, the heat exchange module 610 includes three heat exchangers, one L-shaped heat exchanger and two vertically arranged U-shaped heat exchangers, and the two vertically arranged U-shaped heat exchangers are spliced ​​to one L-shaped heat exchanger.

[0061] There is one first control valve 620, which is connected to the L-shaped heat exchanger; there are two second control valves 630, which are connected to the two corresponding U-shaped heat exchangers. Both the first control valve 620 and the second control valve 630 can be electronic expansion valves.

[0062] It should be noted that in other embodiments, the number of L-shaped heat exchangers can also be multiple vertically arranged, such as two, and the number of U-shaped heat exchangers can be one; of course, the number of both L-shaped and U-shaped heat exchangers can also be multiple.

[0063] In one embodiment of the present invention, the control valve group further includes a controller, which is electrically connected to at least one first control valve 620 and at least one second control valve 630 respectively.

[0064] It is understandable that the controller is connected to the first control valve and the second control valve 630 respectively. The controller can control the opening and closing of the first control valve 620 and the second control valve 630 as well as the flow rate adjustment to adapt to the heat exchange requirements under different operating conditions.

[0065] An embodiment of this utility model also proposes an air conditioning system, which includes a housing and a heat exchanger assembly of any of the above, wherein the heat exchange module 610 is disposed inside the housing.

[0066] It is understood that the first heat exchange component 611 and the second heat exchange component 612 are disposed inside the casing, and the first heat exchange component 611 and the second heat exchange component 612 enclose an installation space, in which the components of the air conditioning system can be arranged; the access port between the first heat exchange component 611 and the second heat exchange component 612 facilitates the maintenance of the components in the installation space.

[0067] Optional, such as Figure 3 As shown, a compressor 700 and a four-way valve 800 located above the compressor 700 are installed inside the housing. The C port 801, S port 802, and E port 803 of the four-way valve 800 are located above the D port 804 of the four-way valve 800. The D port 804 of the four-way valve 800 is connected to the exhaust port of the compressor 700.

[0068] The four-way valve 800 includes a C-port 801, an S-port 802, an E-port, and a D-port 804, as detailed below:

[0069] D-interface 804 (exhaust port) is connected to the exhaust port of compressor 700. In both cooling and heating modes, D-interface 804 is always the exhaust port, used to deliver high-temperature and high-pressure refrigerant gas.

[0070] The S-interface 802 (suction port) is connected to the suction port of the compressor 700 and is used to deliver low-temperature, low-pressure refrigerant gas.

[0071] In cooling mode, C-interface 801 connects to the condenser of the outdoor unit; in heating mode, C-interface 801 connects to the evaporator of the indoor unit.

[0072] In cooling mode, E-interface 803 connects to the evaporator of the indoor unit; in heating mode, E-interface 803 connects to the condenser of the outdoor unit.

[0073] It is understood that in this embodiment, the D port 804 of the four-way valve 800 is located at the bottom, while the C port 801, S port 802, and E port 803 are located at the top. This reduces pipe bends and twists when connecting the C port 801 to the inlet of the high-positioned heat exchanger assembly 600, thereby reducing refrigerant flow resistance and pressure loss, and improving the system's heat exchange efficiency and operational reliability. Simultaneously, reducing bends also avoids stress concentration and vibration noise, extends pipe life, and makes installation and maintenance more convenient.

[0074] It should be noted that if interface D 804 is located at the top, and interfaces C 801, S 802, and E 803 are located at the bottom, in a three-pipe model, the four-way valve 800 needs to block interface E 803 or interface C 801. After blocking interface E 803, the four-way valve 800 only has three interfaces (D, S, C), thus realizing the function of a three-way valve. After blocking interface C 801, the four-way valve 800 only has three interfaces (D, S, E), thus realizing the function of a three-way valve. During use, the blocked interface E 803 or interface C 801 is prone to liquid accumulation. The accumulated liquid may cause liquid slugging when the compressor 700 starts or the valve is switched, damaging the internal components of the compressor 700. In this embodiment, by placing the easily blocked interfaces (E / C) at a high position, the liquid is naturally returned to the system circulation by gravity, which can eliminate the risk of liquid accumulation. At the same time, the bottom interface D 804 design ensures that the lubricating oil flows smoothly back to the compressor 700.

[0075] In one embodiment of this utility model, such as Figures 4 to 6 As shown, a gas-liquid separator 910 is installed inside the housing, and the bottom of the gas-liquid separator 910 is connected to the suction port of the compressor 700 through an oil return pipe 920.

[0076] Understandably, the function of the gas-liquid separator 910 is to separate gaseous and liquid refrigerant and return lubricating oil (oil separator) to the compressor 700 to ensure its normal operation. When liquid refrigerant and lubricating oil accumulate at the bottom of the gas-liquid separator 910, the liquid (liquid refrigerant) at the bottom of the gas-liquid separator 910 is transported to the compressor 700 through the oil return pipe 920 to prevent insufficient lubricating oil from causing wear or malfunction of the compressor 700.

[0077] It should be noted that excessive liquid refrigerant may flow back to the compressor 700, causing liquid slugging in the compressor 700 and damaging it. Therefore, in this embodiment, a third control valve 930 is provided on the oil return pipe 920 to regulate the amount of liquid refrigerant delivered to the compressor 700 from the bottom of the gas-liquid separator 910.

[0078] In this embodiment, the third control valve 930 can be a solenoid valve. The solenoid valve is arranged at the bottom of the gas-liquid separator 910 to replenish the liquid refrigerant at the bottom of the gas-liquid separator 910 to the compressor 700. When the discharge temperature of the compressor 700 is too low or when it starts, the solenoid valve is closed to avoid liquid return. When the discharge temperature of the compressor 700 reaches the preset value, the solenoid valve is opened.

[0079] Furthermore, the compressor 700 is equipped with a temperature measuring element at its exhaust port to measure the exhaust temperature of the compressor 700, and adjusts the opening of the third control valve 930 based on the exhaust temperature.

[0080] For example, the third control valve 930 uses an electronic expansion valve. When the electronic expansion valve is open, the current exhaust temperature is measured by a temperature measuring element. If the current exhaust temperature is lower than a preset value, the opening of the electronic expansion valve is reduced to avoid liquid backflow; if the current exhaust temperature is higher than the preset value, the opening of the electronic expansion valve is increased.

[0081] In one embodiment of the present invention, the housing has a chassis 100, and the bottom of the gas-liquid separator 910 has a gas separation support 940, which is detachably connected to the chassis 100.

[0082] Understandably, the housing has a chassis 100, and the gas-liquid separator 910 is mounted on the chassis 100 via a gas separation bracket 940. The gas separation bracket 940 and the chassis 100 are detachably connected, which facilitates the installation and removal of the gas-liquid separator 910.

[0083] Optionally, the third control valve 930 is installed on the gas distribution bracket 940, which can effectively prevent valve body displacement or interface loosening caused by pipeline vibration and reduce the risk of refrigerant leakage.

[0084] In one embodiment of the present invention, the heat exchange module 610 includes a first heat exchange component 611 and a second heat exchange component 612 arranged opposite to each other along the length of the housing. The first heat exchange component 611 and the second heat exchange component 612 are disposed on the inner wall of the housing, and an installation space is formed between the first heat exchange component 611 and the second heat exchange component 612. The compressor 700, the four-way valve 800 and the gas-liquid separator 910 are arranged in the installation space.

[0085] It is understandable that the first heat exchange component 611 and the second heat exchange component 612 form an installation space, and the compressor 700, the four-way valve 800 and the gas-liquid separator 910 are placed inside the installation space formed by the two heat exchange components, making the system piping connection more compact, which helps to reduce the bending and twisting of the piping, reduce the resistance in the refrigerant flow process, and thus improve the overall energy efficiency and reliability of the system.

[0086] In one embodiment of this utility model, the chassis 100 is provided with a support assembly 200, and the chassis 100 and the support assembly 200 form a support structure, such as... Figures 7 to 9 As shown, the bracket assembly 200 has a first mounting position 201 and a second mounting position 202 adjacent to the first mounting position 201. The first mounting position 201 is used to mount the oil separator 300, and the second mounting position 202 is used to mount the solenoid valve 400.

[0087] It is understood that the support structure includes a chassis 100 and a support assembly 200 disposed on the chassis 100. The support assembly 200 has a first mounting position 201 for mounting an oil separator 300 and a second mounting position 202 for mounting a solenoid valve 400, thereby realizing the integrated design of the oil separator 300 and the solenoid valve 400 on the support assembly 200.

[0088] It should be noted that in existing top-discharge multi-split air conditioning systems, the oil separator 300 and solenoid valve 400 are each assembled inside the casing. Due to the limited space inside the casing, the installation process of the oil separator 300 and solenoid valve 400 is time-consuming and labor-intensive, resulting in low production efficiency. This invention uses a bracket assembly 200 with a first mounting position 201 and a second mounting position 202. The oil separator 300 and solenoid valve 400 are pre-assembled in the first mounting position 201 and the second mounting position 202 respectively, facilitating the integrated design of the oil separator 300 and solenoid valve 400 on the bracket assembly 200. The bracket structure integrating the oil separator 300 and solenoid valve 400 enables rapid assembly inside the casing, thereby improving production efficiency.

[0089] Specifically, such as Figure 7 and Figure 8 As shown, the first mounting position 201 and the second mounting position 202 are arranged adjacent to each other, so that the positions of the oil separator 300 and the solenoid valve 400 are fixed and arranged close to each other, realizing a compact integrated design inside the system, effectively simplifying the pipeline layout inside the housing and reducing the space occupied inside the housing.

[0090] It should be noted that the oil separator 300 and the solenoid valve 400 are arranged close to each other, which shortens the connecting pipeline between the oil separator 300 and the solenoid valve 400, reduces the number of bends and pipeline pressure drop, and improves system energy efficiency.

[0091] The bracket structure provided in this embodiment of the utility model, by designing a first mounting position 201 for mounting the oil separator 300 and a second mounting position 202 for mounting the solenoid valve 400 on the bracket assembly 200, realizes the integrated design of the oil separator 300 and the solenoid valve 400 on the bracket assembly 200. The bracket structure integrating the oil separator 300 and the solenoid valve 400 can realize rapid assembly inside the machine housing, thereby improving production efficiency.

[0092] It is understood that the air conditioning system in this embodiment can achieve the integrated design of oil separator 300 and solenoid valve 400 on bracket assembly 200 through bracket structure. The bracket structure integrating oil separator 300 and solenoid valve 400 can achieve rapid assembly inside the housing, thereby improving production efficiency and maintenance convenience.

[0093] In one embodiment of the present invention, the bracket assembly 200 is detachably connected to the chassis 100, thereby facilitating the separation of the bracket assembly 200 from the chassis 100 for maintenance of the oil separator 300 and the solenoid valve 400 on the bracket assembly 200.

[0094] It should be noted that in other embodiments, the bracket assembly 200 can also be fixedly connected to the chassis 100, such as by welding; the chassis 100 is detachably connected inside the housing, which facilitates the maintenance of the components (oil separator 300 and solenoid valve 400) on the bracket structure.

[0095] Optionally, the oil separator 300 and the support assembly 200, and the solenoid valve 400 and the support assembly 200 are connected by a quick-release structure, so that the oil separator 300 or the solenoid valve 400 can be inspected and repaired separately through the quick-release structure during maintenance, thereby improving the convenience of maintenance.

[0096] In one embodiment of this utility model, such as Figures 7 to 9 As shown, the bracket assembly 200 includes a mounting bracket 210 and a first connecting beam 220. The mounting bracket 210 is provided with a first mounting position 201, which includes a mounting hole 211 and a first connecting part 212. The mounting hole 211 is used to place the oil separator 300, and the first connecting part 212 is used to connect with the oil separator 300. The first connecting beam 220 is connected to the mounting bracket 210, and the first connecting beam 220 is provided with a second mounting position 202.

[0097] It is understood that the oil separator 300 is arranged in the mounting hole 211 of the mounting bracket 210 and connected to the oil separator 300 through the first connecting part 212, so as to fix the oil separator 300 on the mounting bracket 210; the first connecting beam 220 is connected to the mounting bracket 210, and the solenoid valve 400 is installed in the second mounting position 202 on the first connecting beam 220.

[0098] Optionally, the first connecting part 212 is a first connecting hole opened on the mounting bracket 210, and a positioning plate is connected to the first connecting hole. The positioning plate abuts against the outer side wall of the oil separator 300. For example, the positioning plate can be L-shaped, with one end of the positioning plate connected to the first connecting hole and the other end of the positioning plate abutting against the outer side wall of the oil separator 300.

[0099] It is understood that each mounting bracket 210 has multiple first connecting parts 212 located outside the mounting hole 211, thereby achieving the fixed installation of the oil separator 300 on the mounting bracket 210 through the positioning plates on the multiple first connecting parts 212.

[0100] In this embodiment, each mounting bracket 210 is provided with three first connecting parts 212. The mounting bracket 210 is arranged vertically and has a first side and a second side that are opposite each other in the horizontal direction. Two first connecting parts 212 are located on the first side of the mounting bracket 210, and the remaining first connecting part 212 is located on the second side of the mounting bracket 210 and is located vertically between the two first connecting parts 212 on the first side.

[0101] In one embodiment of this utility model, such as Figure 8 and Figure 9 As shown, the second mounting position 202 includes a plurality of second connecting parts 221 spaced apart on the first connecting beam 220, the second connecting parts 221 being used to connect to the solenoid valve 400.

[0102] Optionally, the second connecting part 221 is a second connecting hole opened on the first connecting beam 220, through which the solenoid valve 400 is fixedly installed on the first connecting beam 220; there can be multiple second connecting parts 221, so that multiple solenoid valves 400 can be installed.

[0103] In this embodiment, four second connecting parts 221 are arranged on the first connecting beam 220. Each second connecting part 221 includes two second connecting holes spaced apart in the horizontal direction. The two second connecting holes can realize the installation of a solenoid valve 400.

[0104] In a preferred embodiment of this utility model, such as Figure 8 and Figure 9 As shown, the bracket assembly 200 also includes a second connecting beam 230, which is connected to the mounting bracket 210. The second connecting beam 230 is provided with a first fixing component 240, which is used to fix the first pipeline 500, which is connected to the solenoid valve 400.

[0105] Understandably, the mounting bracket 210 is also connected to a second connecting beam 230, and a first fixing component 240 is arranged on the second connecting beam 230. The first fixing component 240 is used to fix the pipeline connected to the solenoid valve 400, prevent pipeline vibration, significantly reduce the risk of pipeline cracking caused by long-term mechanical fatigue, improve pipeline service life, ensure the sealing reliability of the connection between the solenoid valve 400 and the first pipeline 500, reduce abnormal noise caused by pipeline resonance, reduce system operating noise, and significantly improve user comfort.

[0106] Optional, such as Figures 11 to 14As shown, the first fixing component 240 includes a fixing clip 241, which is detachably connected to the second connecting beam 230. An installation space for installing the first pipeline 500 is formed between the fixing clip 241 and the second connecting beam 230, thereby enabling the installation and removal of the first pipeline 500 on the second connecting beam 230 through the fixing clip 241.

[0107] Furthermore, the first fixing component 240 also includes a flexible component 242, which is disposed in the installation space and has an assembly hole through which the first pipeline 500 passes, thereby improving the stability of fixing the first pipeline 500.

[0108] For example, the first fixing component 240 includes a fixing clip 241 and a flexible component 242. The fixing clip 241 includes a positioning part and two connecting ears. The positioning part has an arc-shaped cross-section. The two connecting ears are respectively connected to the two ends of the positioning part. The connecting ears are provided with second connecting holes. The second connecting beam 230 is provided with third connecting holes that correspond to the second connecting holes. The flexible component 242 is fixed on the second connecting beam 230 and located in the two third connecting holes. The flexible component 242 has an assembly hole for the first pipeline 500 to pass through. The upper surface of the flexible component 242 is an arc surface that mates with the positioning part. The two second connecting holes of the fixing clip 241 are respectively connected to the two third connecting holes on the second connecting beam 230 to fix the first pipeline 500 on the second connecting beam 230. The flexible component 242 also improves the stability of the first pipeline 500 and reduces the vibration of the first pipeline 500.

[0109] In this embodiment, the flexible component 242 is provided with a tensioning groove, which enables the flexible component 242 to have adjustable elastic deformation capability, adapting to different pipe diameters of the first pipeline, and the tensioning groove can absorb the vibration energy during system operation through controllable deformation, effectively preventing the first pipeline 500 from loosening; the tensioning groove will generate a self-locking effect under the action of pre-tightening force, so that the fixing clamp 241 maintains a stable clamping force under long-term vibration conditions.

[0110] In a preferred embodiment of this utility model, such as Figure 14 As shown, the fixing clamp 241 has a limiting part 2411 that abuts against the end face of the flexible member 242, so that the limiting part 2411 and the end face of the flexible member 242 form a rigid stop to prevent the fixing clamp 241 from moving.

[0111] In this embodiment, the limiting part 2411 is a limiting plate connected to the positioning part, and two limiting plates with a gap are arranged on the same end face of the flexible member 242; preferably, the limiting part 2411 has a limiting part 2411 on both opposite sides, so that the two end faces of the flexible member 242 are arranged with limiting plates, further restricting the position of the fixing clip 241.

[0112] In one specific embodiment of this utility model, the bracket assembly 200 includes two mounting brackets 210 arranged at intervals along the horizontal direction. A first connecting beam 220 connects the upper parts of the two mounting brackets 210, and a second connecting beam 230 connects the lower parts of the two mounting brackets 210. Two oil separators 300 are respectively fixed to the two mounting brackets 210. It should be noted that the number of oil separators 300 is adjusted according to the number of compressors: two oil separators 300 are used for dual compressors, and one oil separator 300 is used for single compressors.

[0113] Understandably, the two mounting brackets 210 are connected by the first connecting beam 220 and the second connecting beam 230 to improve the overall stability of the bracket assembly 200.

[0114] Optionally, the number of second mounting positions 202 on the second connecting beam 230 may be less than the number of first mounting positions 201 on the first connecting beam 220. The pipelines connected to some of the solenoid valves 400 on the first mounting position 201 are directly connected to other components inside the housing, or fixed by the pipeline bracket 250.

[0115] In this embodiment, the first connecting beam 220 has four first mounting positions 201 arranged horizontally, and the second connecting beam 230 has two second mounting positions 202 arranged horizontally. Each second mounting position 202 is connected to a first fixing component 240. It should be noted that the number of first mounting positions 201 on the first connecting beam 220 and the number of second mounting positions 202 on the second connecting beam 230 can be reasonably designed according to actual needs.

[0116] Furthermore, such as Figure 11 As shown, the mounting bracket 210 is connected to the pipe bracket 250, which has a third mounting position for fixing other pipes in the system to improve the stability of the pipes.

[0117] It is understood that the pipe support 250 includes a connecting plate connected to the mounting bracket 210, and a second fixing component 260 is provided on the connecting plate. The second fixing component 260 forms a third mounting position to fix the pipe.

[0118] It should be noted that the second fixing component 260 can adopt the same structure as the first fixing component 240, which will not be described in detail here.

[0119] In this embodiment, there are two pipe supports 250, one of which is located on the side of one of the mounting brackets 210, and the other is located at the bottom of the other mounting bracket 210. Of course, in other embodiments, the number and arrangement of the pipe supports 250 can be reasonably designed according to actual needs.

[0120] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
