Description

Technical Field

[0001] This application relates to, but is not limited to, the technical field of heat pump units, and specifically refers to an air source heat pump unit. Background Art

[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source (air) to a high-level heat source. It is a form of heat pump. As the name implies, a heat pump can, like a pump, convert low-level thermal energy that cannot be directly utilized (such as the heat contained in air, soil, or water) into high-level thermal energy that can be utilized, thereby achieving the purpose of saving some high-level energy (such as coal, gas, oil, electric energy, etc.).

[0003] For traditional air source heat pump units, in order to meet the power requirements, it is usually necessary to newly develop an integrated high-power modular machine, which requires high input costs, occupies a lot of development resources, and has a long cycle. Summary of the Invention

[0045] The principles and features of the present application will be described below in conjunction with the attached drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0046] As Figure 1 shown, an air source heat pump unit provided by an embodiment of the present application includes: a base 31, a first heat pump module 1, a second heat pump module 2, a water pipe assembly 4, and a total electronic control box 5.

[0047] Among them, the first heat pump module 1 is arranged on the base 31. The first heat pump module 1 is provided with a first waterway interface. The second heat pump module 2 is arranged on the base 31 and is arranged side by side with a space interval from the first heat pump module 1, so that there is an installation space 34 between the second heat pump module 2 and the first heat pump module 1. The second heat pump module 2 is provided with a second waterway interface.

[0048] The water pipe assembly 4 is arranged in the installation space 34 and is connected to the first waterway interface and the second waterway interface.

[0049] The main electric control box 5 is arranged in the installation space 34 and is electrically connected to the first heat pump module 1 and the second heat pump module 2.

[0050] The air source heat pump unit provided by the embodiment of the present application includes a base 31, a first heat pump module 1, a second heat pump module 2, a water pipe assembly 4 and a main electric control box 5. The first heat pump module 1 and the second heat pump module 2 are two independent and complete heat pump modules, both of which include a refrigerant system and a waterway system, and can realize the function of the air source heat pump when making waterway connection and circuit connection separately. The refrigerant system generally includes structures such as a compressor, a first refrigerant heat exchanger, a throttling device, a second refrigerant heat exchanger, a control valve (such as a four-way valve) connected through refrigerant pipelines. The refrigerant system can be connected to form a refrigeration cycle flow path and / or a heating cycle flow path to realize refrigeration cycle and / or heating cycle. The first refrigerant heat exchanger is a wind-side heat exchanger, specifically a fin heat exchanger, which exchanges heat with the outside air. The second refrigerant heat exchanger exchanges heat with the waterway system of the heat pump module to heat or cool the water in the waterway system. The waterway system is connected to the user-side waterway system through the water pipe assembly 4, and then heats or cools the user side. The user-side waterway system can include any one or more of the waterway systems that realize heat exchange through water, such as an air conditioner indoor unit, a water heater, a heater, etc. Correspondingly, the air source heat pump unit can be an air source heat pump air conditioner unit, an air source heat pump water heater unit, an air source heat pump heater unit or a unit with multiple functions mentioned above. The main electric control box 5 is used to uniformly control the first heat pump module 1 and the second heat pump module 2, and communication lines, power lines and other lines can be arranged in the main electric control box 5. The base 31 connects the above-mentioned first heat pump module 1, second heat pump module 2, water pipe assembly 4 and main electric control box 5 together to form a modular unit.

[0051] In the embodiment of the present application, the first heat pump module 1 and the second heat pump module 2 are assembled, and the water pipe assembly 4 is used to uniformly connect to the user-side water system externally, and the main electric control box 5 is used for unified control. It is equivalent to assembling two complete heat pump modules to form an air source heat pump unit, which can meet the requirements of high-power scenarios. However, the structure of a single heat pump module is relatively simple, and only the water pipe assembly 4 and the main electric control box 5 need to be reasonably designed. Therefore, it does not need to occupy too much development resources, which is beneficial to reducing development resources, improving development efficiency and shortening the development cycle.

[0052] In an exemplary embodiment, the second waterway interface is disposed opposite to the first waterway interface, as Figure 2 shown.

[0053] The first waterway interface of the first heat pump module 1 is disposed opposite to the second waterway interface of the second heat pump module 2. Therefore, the water pipe assembly 4 can be centrally disposed between the first heat pump module 1 and the second heat pump module 2 for waterway connection. In this way, the distances between the waterway systems of the two heat pump modules and the water pipe assembly 4 are both small, which is beneficial to shortening the waterway path and avoiding the detour of the water pipes, thereby facilitating the simplification of the waterway connection structure. The total electric control box 5 is also located between the first heat pump module 1 and the second heat pump module 2, so that the distance between the total electric control box 5 and the two heat pump modules is also small, which is also beneficial to simplifying the circuit connection structure. In addition, the installation space 34 between the first heat pump module 1 and the second heat pump module 2 is relatively large, which is convenient for installation and later maintenance.

[0054] In one embodiment, the first heat pump module 1 and the second heat pump module 2 have the same structure, and the first heat pump module 1 and the second heat pump module 2 form a centrosymmetric structure. After the first heat pump module 1 rotates 180°, it becomes the second heat pump module 2, as Figure 2 shown. In this way, the first heat pump module 1 and the second heat pump module 2 are substantially the same heat pump module. When assembling, it is only necessary to place them in the set positions to ensure that the first waterway interface is disposed opposite to the second waterway interface. This can further reduce the development resources and further shorten the development cycle.

[0055] In an exemplary embodiment, as Figure 1 shown, the air source heat pump unit further includes: a top frame connecting plate 32 and a middle frame connecting plate 33. The top frame connecting plate 32 connects the top of the first heat pump module 1 and / or the top of the second heat pump module 2. The middle frame connecting plate 33 connects the middle of the first heat pump module 1 and / or the middle of the second heat pump module 2.

[0056] In this way, the bottoms, middles and tops of the first heat pump module 1 and the second heat pump module 2 are relatively fixed, effectively enhancing the structural stability of the entire unit.

[0057] In addition, the top frame connecting plate 32 and the middle frame connecting plate 33 can also be used to fix the following structures such as the first baffle 35, the first enclosure 36, the second baffle 37, the second enclosure 38, etc., thereby avoiding excessive drilling on the first heat pump module 1 and the second heat pump module 2, and also being beneficial to reducing the assembly difficulty of the unit.

[0058] Among them, four top frame connection plates 32 can be provided in the front, back, left, and right directions. The front top frame connection plate 32 connects the front top of the first heat pump module 1 and the front top of the second heat pump module 2. The rear top frame connection plate 32 connects the rear top of the first heat pump module 1 and the rear top of the second heat pump module 2. The left top frame connection plate 32 connects the left top of the first heat pump module 1. The right top frame connection plate 32 connects the right top of the second heat pump module 2.

[0059] Four middle frame connection plates 33 can be provided in the front, back, left, and right directions along the circumference of the installation space 34. The front top frame connection plate 32 connects the middle of the front end of the first heat pump module 1 and the middle of the front end of the second heat pump module 2. The rear top frame connection plate 32 connects the middle of the rear end of the first heat pump module 1 and the middle of the rear end of the second heat pump module 2. The left top frame connection plate 32 connects the middle of the right end of the first heat pump module 1. The right top frame connection plate 32 connects the middle of the left end of the second heat pump module 2.

[0060] In an exemplary embodiment, as Figure 2 shown, the first heat pump module 1 includes a first compressor module, a first electric control module 14, and a first water-side heat exchanger 11. The first water circuit interface includes the water inlet and outlet of the first water-side heat exchanger 11. The second heat pump module 2 includes a second compressor module, a second electric control module 24, and a second water-side heat exchanger 21. The second water circuit interface includes the water inlet and outlet of the second water-side heat exchanger 21.

[0061] Among them, as Figure 2 shown, the first water-side heat exchanger 11, the water pipe assembly 4, and the second water-side heat exchanger 21 are arranged in parallel at intervals in sequence. The first electric control module 14 is arranged on one side in the length direction of the first water-side heat exchanger 11. The second electric control module 24 is arranged on one side in the length direction of the second water-side heat exchanger 21. The first compressor module is arranged on the side of the first water-side heat exchanger 11 away from the second water-side heat exchanger 21. The second compressor module is arranged on the side of the second water-side heat exchanger 21 away from the first water-side heat exchanger 11.

[0062] The first compressor module may include at least one first compressor 12, such as one first compressor 12, two first compressors 12, or more first compressors 12. The second compressor module may include at least one second compressor 22, such as one second compressor 22, two second compressors 22, or more second compressors 22.

[0063] The first water-side heat exchanger 11 and the second water-side heat exchanger 21 can be plate heat exchangers, which are internally provided with both a water flow path and a refrigerant flow path. The two ends of the water flow path are the water inlet and the water outlet, and the two ends of the refrigerant flow path are the refrigerant inlet and the refrigerant outlet. In this way, the second refrigerant heat exchanger of the first heat pump module 1 is equivalent to being integrated in the first water-side heat exchanger 11, and heat exchange between the refrigerant system and the water system of the first heat pump module 1 is realized within the first water-side heat exchanger 11. Similarly, the second refrigerant heat exchanger of the second heat pump module 2 is equivalent to being integrated in the second water-side heat exchanger 21, and heat exchange between the refrigerant system and the water system of the second heat pump module 2 is realized within the second water-side heat exchanger 21.

[0064] As Figure 2 shown, the first water-side heat exchanger 11 and the second water-side heat exchanger 21 can be generally thick tubular in appearance and are arranged in parallel at intervals on both sides of the installation space 34. The water pipe assembly 4 is arranged in parallel between the first water-side heat exchanger 11 and the second water-side heat exchanger 21. In this way, the water circuit structure of the whole unit is compact and convenient for water circuit connection. The first electronic control module 14 is located on one side in the length direction of the first water-side heat exchanger 11, and the first compressor module is located on the side of the first water-side heat exchanger 11 away from the second water-side heat exchanger 21. Therefore, the position of the first water-side heat exchanger 11 is relatively inward, which is convenient for connecting with the water pipe assembly 4. The positions of the first electronic control module 14 and the first compressor module are relatively outward, which is convenient for inspection and maintenance. Similarly, the second electronic control module 24 is located on one side in the length direction of the second water-side heat exchanger 21, and the second compressor module is located on the side of the second water-side heat exchanger 21 away from the first water-side heat exchanger 11. Therefore, the position of the second water-side heat exchanger 21 is relatively inward, which is convenient for connecting with the water pipe assembly 4. The positions of the second electronic control module 24 and the second compressor module are relatively outward, which is convenient for inspection and maintenance.

[0065] In an exemplary embodiment, the water pipe assembly 4 includes a water inlet pipe 44 and a water outlet pipe 45, as Figure 2 shown. The water inlet pipe 44 is provided with a total water inlet 441, a first water inlet interface 442, and a second water inlet interface 443, as Figure 4 shown. The water outlet pipe 45 is provided with a total water outlet 451, a first water outlet interface 452, and a second water outlet interface 453, as Figure 3 shown. The total water inlet 441 and the total water outlet 451 are arranged to connect to the user-side water circuit system. The first water inlet interface 442 and the first water outlet interface 452 are arranged to connect to the water inlet and the water outlet of the first water-side heat exchanger 11. The second water inlet interface 443 and the second water outlet interface 453 are arranged to connect to the water inlet and the water outlet of the second water-side heat exchanger 21.

[0066] As Figure 2As shown, the water inlet pipe 44 and the water outlet pipe 45 are arranged in parallel. The main electric control box 5 is arranged on one side in the length direction of the water pipe assembly 4. The main water inlet 441 is arranged at one end of the water inlet pipe 44 away from the main electric control box 5, and the main water outlet 451 is arranged at one end of the water outlet pipe 45 away from the main electric control box 5.

[0067] In this way, the main water inlet 441 and the main water outlet 451 of the water pipe assembly 4 are located at one end of the installation space 34, and the main electric control box 5 is located at the other end of the installation space 34. This is equivalent to separating water and electricity, which is convenient for the circuit connection of the main electric control box 5 with the external circuit system, the first heat pump module 1 and the second heat pump module 2, and is also convenient for the docking of the main water inlet 441 and the main water outlet 451 with the user-side water circuit system, and the layout is relatively reasonable.

[0068] In an exemplary embodiment, the first water-side heat exchanger 11 and the second water-side heat exchanger 21 have the same structure, the inner diameter of the water inlet pipe 44 is equal to the inner diameter of the water outlet pipe 45, and the path length from the main water inlet 441 through the first water-side heat exchanger 11 to the main water outlet 451 is L1, and the path length from the main water inlet 441 through the second water-side heat exchanger 21 to the main water outlet 451 is L2, where L1 = L2.

[0069] This can achieve uniform water flow distribution between the first heat pump module 1 and the second heat pump module 2, make the water pressure of the water circuit systems of the first heat pump module 1 and the second heat pump module 2 equivalent, meet the design requirements, and further help the first heat pump module 1 and the second heat pump module 2 to maintain good working energy efficiency, and avoid the influence on the working energy efficiency of a single heat pump module due to too high or too low water pressure of a single heat pump module.

[0070] In some embodiments, the water inlet pipe 44 and the water outlet pipe 45 can be composed of a hard pipe and a flexible pipe, which is convenient for adjusting the size, can adapt to a certain amount of assembly error, and is convenient for installation. The flexible pipe can be arranged between the main water inlet 441 and the user-side water circuit system and between the main water outlet 451 and the user-side water circuit system. The flexible pipe can be arranged as a corrugated pipe.

[0071] In an exemplary embodiment, as Figure 2 shown, the water inlet and the water outlet of the first water-side heat exchanger 11 are arranged at intervals along the length direction of the first water-side heat exchanger 11. The water inlet and the water outlet of the second water-side heat exchanger 21 are arranged at intervals along the length direction of the second water-side heat exchanger 21. And, the water inlet of the first water-side heat exchanger 11 is arranged opposite to the water outlet of the second water-side heat exchanger 21, and the water outlet of the first water-side heat exchanger 11 is arranged opposite to the water inlet of the second water-side heat exchanger 21. The first water inlet interface 442 and the second water inlet interface 443 are arranged at intervals along the length direction of the water inlet pipe 44. The first water outlet interface 452 and the second water outlet interface 453 are arranged at intervals along the length direction of the water outlet pipe 45.

[0072] As Figure 2 shown, the water inlet pipe 44 and the water outlet pipe 45 are arranged side by side along the height direction of the air source heat pump unit. One of the water inlet pipe 44 and the water outlet pipe 45 located on the upper side is connected to the first water-side heat exchanger 11 and the second water-side heat exchanger 21 respectively through two adapter pipes 43.

[0073] Taking the direction in the attached drawings of the specification as an example, the height direction of the air source heat pump unit is the up and down direction. The width direction of the air source heat pump unit can be the arrangement direction of the first heat pump module 1 and the second heat pump module 2, that is, the left and right direction. The thickness direction of the air source heat pump unit can be the length direction of the water pipe assembly 4, that is, the front and back direction.

[0074] In other words, the water inlet pipe 44 and the water outlet pipe 45 are arranged in a stacked manner with high and low dislocation, making full use of the space in the height direction of the installation space 34, which is beneficial to reducing the distance between the first heat pump module 1 and the second heat pump module 2, and further beneficial to reducing the floor area of the unit. It is also beneficial to simplify the connection structure between the water pipe assembly 4 and the first water-side heat exchanger 11 and the second water-side heat exchanger 21, and avoid complex structures such as water path crossing and detouring.

[0075] In one example, the water inlet pipe 44 is located above the water outlet pipe 45, as Figure 2 shown.

[0076] In one embodiment, as Figure 4 shown, the adapter pipe 43 includes a first horizontal pipe section 431, a first arc pipe section 434, a vertical pipe section 432, a second arc pipe section 435 and a second horizontal pipe section 433 that are smoothly connected in sequence. The first horizontal pipe section 431 can be parallel to the second horizontal pipe section 433 and perpendicular to the vertical pipe section 432. The first horizontal pipe section 431 can be located above the second horizontal pipe section 433.

[0077] In another embodiment, as Figure 5 shown, the adapter pipe 43 includes a first horizontal pipe section 431, a vertical pipe section 432 and a second horizontal pipe section 433 that are connected in sequence. The center line of the interface between the first horizontal pipe section 431 and the vertical pipe section 432 is inclined with respect to the center line of the vertical pipe section 432. The center line of the interface between the second horizontal pipe section 433 and the vertical pipe section 432 is inclined with respect to the center line of the vertical pipe section 432. The first horizontal pipe section 431 can be parallel to the second horizontal pipe section 433 and perpendicular to the vertical pipe section 432. The first horizontal pipe section 431 can be located above the second horizontal pipe section 433.

[0078] When the adapter pipe 43 includes a first arc pipe section 434 and a second arc pipe section 435, the turning parts of the adapter pipe 43 are all transitioned by elbow joints, so that the shapes of each pipe section are more regular, the interfaces between each pipe section are more regular, and it is convenient for welding.

[0079] When the adapter pipe 43 does not include the first arc pipe section 434 and the second arc pipe section 435, the turning part of the adapter pipe 43 is not transitioned by a bend joint, but is directly connected using an inclined mouth structure. This solution is beneficial for reducing the number of interfaces and welding amount of the adapter pipe 43, reducing production costs, and making the sealing reliability of the water pipe assembly 4 higher and the economy better.

[0080] In an exemplary embodiment, as Figure 3 and Figure 6 shown, the air source heat pump unit further includes: a water pipe support member 6, connected to the base 31 and configured to support the water pipe assembly 4.

[0081] The provision of the water pipe support member 6 can play a good role in supporting and fixing the water pipe assembly 4, thereby facilitating the reduction of the risk of water leakage caused by vibration, swaying, or even displacement of the water pipe assembly 4 during use.

[0082] In an exemplary embodiment, the water pipe assembly 4 includes a first pipeline 41 and a second pipeline 42 arranged in parallel along the height direction of the air source heat pump unit, as Figure 3 and Figure 4 shown. The first pipeline 41 is located below the second pipeline 42, and one of the first pipeline 41 and the second pipeline 42 is the water outlet pipe 45, and the other is the water inlet pipe 44.

[0083] As Figure 3 and Figure 6 shown, the water pipe support member 6 includes a first support member 61 and a second support member 62. The bottom of the first support member 61 is fixedly connected to the base 31. The bottom of the second support member 62 is fixedly connected to the top of the first support member 61. And, the first support member 61 and the second support member 62 enclose a space for the second pipeline 42 to pass through. The first support member 61 supports and fixes the first pipeline 41, and the second support member 62 supports and fixes the second pipeline 42.

[0084] Therefore, the first pipeline 41 and the second pipeline 42 are arranged in a stacked manner with a high-low offset, making full use of the space in the height direction of the installation space 34, facilitating the reduction of the distance between the first heat pump module 1 and the second heat pump module 2, and further facilitating the reduction of the floor area of the unit. It is also beneficial for simplifying the connection structure between the water pipe assembly 4 and the first water-side heat exchanger 11 and the second water-side heat exchanger 21, and avoiding complex structures such as water path intersections and detours.

[0085] Correspondingly, the water pipe support member 6 includes a first support member 61 and a second support member 62, and the first support member 61 and the second support member 62 are arranged in a stacked manner to respectively support and fix the first pipeline 41 and the second pipeline 42.

[0086] The number of the water pipe supports 6 can be multiple. The multiple water pipe supports 6 are arranged at intervals along the length direction of the water pipe assembly 4 to support and fix multiple parts of the water pipe assembly 4, which is beneficial to further improve the stability and reliability of the water pipe assembly 4.

[0087] For example: the number of the water pipe supports 6 is two. As Figure 3 shown, the two water pipe supports 6 are respectively arranged at positions close to both ends of the water pipe assembly 4 along the length direction.

[0088] In an exemplary embodiment, as Figure 3 and Figure 6 shown, the projection of the second support 62 on the base 31 is located within the projection of the first support 61 on the base 31.

[0089] In other words, the size of the first support 61 is relatively large, and the size of the second support 62 is relatively small. In this way, compared with the second support 62, the first support 61 has higher strength. Since the second support 62 only supports the second pipeline 42, while the first support 61 substantially supports the first pipeline 41, the second support 62 and the second pipeline 42, the strength of the second support 62 needs to be higher, which is beneficial to improve the overall strength, stability and reliability of the water pipe support 6, and further beneficial to improve the stability and reliability of the water pipe assembly 4.

[0090] In an exemplary embodiment, the first support 61 includes a first connecting arm 611, a first supporting arm 612 and a second connecting arm 613 connected in sequence. As Figure 3 shown, both the first connecting arm 611 and the second connecting arm 613 are fixedly connected to the base 31, and the first supporting arm 612 supports and fixes the first pipeline 41.

[0091] The first support 61 includes a first connecting arm 611, a first supporting arm 612 and a second connecting arm 613. The first connecting arm 611, the first supporting arm 612 and the second connecting arm 613 are sequentially connected in a turning manner to form a semi-surrounding structure with the opening facing downwards. The first supporting arm 612 is located at a higher position and can support and fix the first pipeline 41.

[0092] Wherein, the first supporting arm 612 can be fixedly connected to the first pipeline 41 by means of fastener connection, welding, etc. The first connecting arm 611 and the second connecting arm 613 can be fixedly connected to the base 31 by means of fastener connection, welding, etc. The first connecting arm 611 and the second connecting arm 613 can be parallel to each other and perpendicular to the first supporting arm 612.

[0093] For example: as Figure 3As shown, the first support arm 612 is provided with a connection hole, and a first connection plate 411 is correspondingly arranged on the first pipeline 41. Fasteners (such as screws or bolts) pass through the first connection hole and are fixedly connected to the first connection plate 411 to realize the fixed connection between the first support arm 612 and the first pipeline 41. Connection flanges 63 can be arranged at the lower ends of the first connection arm 611 and the second connection arm 613. Connection holes are arranged on the connection flanges 63, and fasteners such as screws pass through the connection holes on the connection flanges 63 and are fixedly connected to the base 31 to realize the fixed connection between the first connection arm 611, the second connection arm 613 and the base 31.

[0094] In one embodiment, the first support member 61 and the second support member 62 are of an integral structure, such as Figure 3 shown. The second support member 62 includes a second support arm 622 and a third connection arm 621 connected in sequence. The second support arm 622 supports and fixes the second pipeline 42, and the third connection arm 621 is fixedly connected to the first support arm 612.

[0095] In another embodiment, as Figure 6 shown, the first support member 61 and the second support member 62 are of a split assembly structure. The second support member 62 includes a third connection arm 621, a second support arm 622 and a fourth connection arm 623 connected in sequence. The second support arm 622 supports and fixes the second pipeline 42, and both the third connection arm 621 and the fourth connection arm 623 are fixedly connected to the first support arm 612.

[0096] The second support member 62 and the first support member 61 can be of an integral structure. Then, during the production process, after the first support member 61 is fixedly connected to the base 31, the first pipeline 41 and the second pipeline 42 can be installed in sequence. In this case, the second support member 62 does not include the fourth connection arm 623, so the second support arm 622 is a cantilever structure. The second support member 62 and the first support arm 612 enclose a semi-enclosed structure with an opening facing one side (such as the opening facing left). Therefore, the second pipeline 42 can be snapped into the opening of the semi-enclosed structure and then fixedly connected to the first support arm 612. This is beneficial to simplifying the assembly process and reducing the assembly difficulty of the water pipe assembly 4. At this time, the second support arm 622 and the third connection arm 621 can adopt a channel steel structure (with reinforcing plates on both sides), which is beneficial to improving the strength of the second support member 62.

[0097] The second support member 62 and the first support member 61 can also be of a split assembly structure. During the production process, the water pipe support member 6 and the water pipe assembly 4 can be installed in a stacked manner. For example, first fix the first support member 61, then fix the first pipeline 41, then fix the second support member 62, and finally fix the second pipeline 42. In this way, the water pipe assembly 4 has a larger operating space during installation, which is beneficial to reducing the assembly difficulty of the water pipe assembly 4. And in this case, the second support member 62 also includes two connecting arms (i.e., the third connecting arm 621 and the fourth connecting arm 623), so the second support arm 622 is not a cantilever structure, which is beneficial to improving the stability and reliability of the second support member 62. Instead of using a channel steel structure, a flat plate structure or a structure close to a flat plate structure can be directly adopted.

[0098] Among them, the second support arm 622 can be fixedly connected to the second pipeline 42 by means of fastener connection, welding, etc. The third connecting arm 621 and the fourth connecting arm 623 can be fixedly connected to the first support arm 612 by means of fastener connection, welding, etc. The third connecting arm 621 and the fourth connecting arm 623 can be parallel to each other. The third connecting arm 621 can be perpendicular to the second support arm 622.

[0099] For example: as Figure 3 shown, a connection hole is provided on the second support arm 622, and a second connecting plate 421 is correspondingly provided on the second pipeline 42. Fasteners (such as screws, bolts, etc.) pass through the connection hole on the second support arm 622 and are fixedly connected to the second connecting plate 421 to realize the fixed connection between the second pipeline 42 and the second support member 62.

[0100] As Figure 3 shown, when the second support member 62 does not include the fourth connecting arm 623, the third connecting arm 621 can adopt a channel steel structure. A connecting plate is provided at the lower end of the channel steel, and a connection hole is provided on the connecting plate. Fasteners such as screws pass through the connection hole on the connecting plate and are fixedly connected to the first support arm 612 to realize the fixed connection between the second support member 62 and the first support member 61. As Figure 6 shown, when the second support member 62 includes the fourth connecting arm 623, connection flanges 63 can be provided at the lower ends of the third connecting arm 621 and the fourth connecting arm 623. Connection holes are provided on the connection flanges 63. Fasteners such as screws pass through the connection holes on the connection flanges 63 and are fixedly connected to the first support arm 612 to realize the fixed connection between the second support member 62 and the first support member 61.

[0101] In an exemplary embodiment, the first heat pump module 1 includes a first air-side heat exchanger (not shown in the figure), the second heat pump module 2 includes a second air-side heat exchanger (not shown in the figure), and the first air-side heat exchanger and the second air-side heat exchanger are arranged side by side. The air source heat pump unit further includes: a first baffle 35 and at least one first enclosing plate 36, asFigure 7 as shown

[0102] Both the first enclosing plate 36 and the first baffle 35 are fixed to the lower sides of the first air-side heat exchanger and the second air-side heat exchanger. The first enclosing plate 36 covers a part of the side opening of the installation space 34. The first baffle 35, the first enclosing plate 36 and the base 31 enclose a protection space, and the main electric control box 5 and the water pipe assembly 4 are located in the protection space.

[0103] The number of the first enclosing plates 36 can be one. For example, only the first enclosing plate 36 is provided on the front side of the installation space 34, and the rear side of the installation space 34 faces the wall, so the first enclosing plate 36 can be omitted. The number of the first enclosing plates 36 can also be two. As Figure 7 shown, the two first enclosing plates 36 are arranged front and rear, and respectively cover a part of the front and rear openings of the installation space 34.

[0104] The first air-side heat exchanger and the second air-side heat exchanger may include, but are not limited to, at least one fin heat exchanger. For example: the first air-side heat exchanger includes two fin heat exchangers arranged front and rear, and the second air-side heat exchanger includes two fin heat exchangers arranged front and rear. The first air-side heat exchanger may be located in the first air duct, and the first air duct may be top air outlet and side air inlet. The second air-side heat exchanger may be located in the second air duct, and the second air duct may be top air outlet and side air inlet. The first heat pump module 1 further includes at least one first fan 13, such as Figure 1 , Figure 7 and Figure 13 shown, the first fan 13 is used to drive the air flow through the first air duct. The second heat pump module 2 further includes at least one second fan 23, such as Figure 1 , Figure 7 and Figure 13 shown, the second fan 23 is used to drive the air flow through the second air duct.

[0105] The arrangement of the first enclosing plate 36 and the first baffle 35 can play a good protective role for the main electric control box 5 and the water pipe assembly 4, which is beneficial to blocking ultraviolet rays, avoiding the aging and damage of the circuit wires, hoses and other structures in the installation space 34 caused by long-term exposure to sunlight, and is also beneficial to optimizing the appearance of the unit. In addition, this is also beneficial to preventing foreign objects from accumulating in the installation space 34 and affecting the normal operation of the unit.

[0106] When the first heat pump module 1 includes a plurality of first compressors 12, a plurality of first air-side heat exchangers, and a plurality of first fans 13, it is equivalent to that the first heat pump module 1 includes a plurality of first heat pump units. The plurality of first heat pump units are connected in parallel or in series in the front-rear direction, but share the same first water-side heat exchanger 11 and the same first electronic control module 14. Correspondingly, when the second heat pump module 2 includes a plurality of second compressors 22, a plurality of second air-side heat exchangers, and a plurality of second fans 23, it is equivalent to that the second heat pump module 2 includes a plurality of second heat pump units. The plurality of second heat pump units are connected in parallel or in series in the front-rear direction, but share the same second water-side heat exchanger 21 and the same second electronic control module 24.

[0107] In an exemplary embodiment, the first baffle 35 is provided with a drain hole 353, as Figures 8 to 11 shown.

[0108] The arrangement of the drain hole 353 can increase the drainage capacity of the first baffle 35, which is beneficial to avoiding excessive accumulation of rainwater, snow, etc. on the first baffle 35 and having an adverse impact on the following circuits and waterways.

[0109] Among them, the drain hole 353 can be holes or staggered notches of various shapes. A centralized drainage groove can be arranged at the lower part of the drain hole 353, and a centralized drainage joint can be arranged.

[0110] The number of the drain holes 353 can be multiple, and the multiple drain holes 353 are arranged at intervals in the thickness direction of the air source heat pump unit, which is convenient for efficient drainage at multiple positions.

[0111] In an exemplary embodiment, the first baffle 35 is provided with a diversion inclined surface, as Figure 9 , Figure 10 and Figure 11 shown, and the drain hole 353 is arranged at the bottom of the diversion inclined surface.

[0112] The diversion inclined surface can play a role in diverting water, which is beneficial to further improving the drainage capacity of the first baffle 35.

[0113] In an exemplary embodiment, the first baffle 35 is of an integral structure, which is beneficial to simplifying the assembly process.

[0114] Alternatively, the first baffle 35 is of a split assembly structure, which is convenient for simplifying the structures of each component, beneficial to processing and forming, and also convenient for using the misalignment assembly gap between adjacent components as the drain hole 353. That is: the assembly gap of the first baffle 35 forms the drain hole 353.

[0115] In an example, the first baffle 35 is of an integral structure, as Figure 8As shown, the main body of the first baffle 35 is generally in a flat plate structure. A row of drain holes 353 is provided in each of the two side edge regions of the first baffle 35, and each row of drain holes 353 is arranged at intervals in the front-rear direction of the air source heat pump unit.

[0116] In another example, the first baffle 35 is an integral structure, such as Figure 9 As shown, the main body of the first baffle 35 is in an inverted V-shaped structure with the middle high and the two ends low. A row of drain holes 353 is provided in each of the two side edge regions of the first baffle 35, and each row of drain holes 353 is arranged at intervals in the front-rear direction of the air source heat pump unit.

[0117] In yet another example, the first baffle 35 is an integral structure, such as Figure 10 As shown, the main body of the first baffle 35 is in a V-shaped structure with the middle low and the two ends high. Two rows of drain holes 353 are provided in the middle region of the first baffle 35, and each row of drain holes 353 is arranged at intervals in the front-rear direction of the air source heat pump unit.

[0118] In still another example, the first baffle 35 is a split assembly structure. As Figure 11 shown, the first baffle 35 includes a first sub-board 351 and a second sub-board 352. The first sub-board 351 is connected to the second sub-board 352, and the splicing part of the first sub-board 351 and the second sub-board 352 is staggered up and down to form the drain hole 353. In this way, the first baffle 35 and the second baffle 37 adopt a stacked and staggered case method, which can avoid rainwater accumulation on the premise of complete light shielding. It can be that the first sub-board 351 is below and the second sub-board 352 is above. The second sub-board 352 is provided with a plurality of connecting lugs 3521, and the connecting lugs 3521 are fixedly connected to the first sub-board 351 by means of fasteners, welding, etc.

[0119] In an exemplary embodiment, such as Figures 8 to 11 shown, the two ends of the first baffle 35 are respectively provided with a first folding edge 354 and a second folding edge 355. The first folding edge 354 and the second folding edge 355 are provided with connection holes for installing fasteners. The top ends of the first folding edge 354 and the second folding edge 355 are provided with auxiliary support hooks 356 for positioning the first baffle 35.

[0120] During the assembly process, the first baffle 35 can be first hung between the first heat pump module 1 and the second heat pump module 2 by using the auxiliary support hooks 356, such as hanging on the middle frame connecting plate 33 in the installation space 34 or hanging on the first heat pump module 1 and the second heat pump module 2 to play a positioning role. Then, the first folding edge 354 is fixedly connected to the middle frame connecting plate 33 or the first heat pump module 1 by using fasteners such as screws, and the second folding edge 355 is fixedly connected to the middle frame connecting plate 33 or the second heat pump module 2, thereby realizing the assembly and fixation of the first baffle 35.

[0121] The auxiliary hook structure can be formed by continuously bending a part of the first hem 354 and a part of the second hem 355.

[0122] On the first baffle 35, a reinforcing rib 357 can also be provided along the length direction of the first baffle 35 (i.e., the front-back direction in the figure) to enhance the overall structural strength of the first baffle 35.

[0123] In an exemplary embodiment, as Figure 12 shown, one end of the first shroud 36 is provided with a connection hole for installing a fastener, and the other end of the first shroud 36 is provided with a positioning snap structure 361 for positioning the first shroud 36.

[0124] The positioning snap structure 361 can be provided at the lower end of the first shroud 36, and the connection hole can be provided at the upper end of the first shroud 36. A support hem can be provided at the lower end of the first shroud 36, and two downwardly bent hems are provided at the lower end of the support hem, and these hems form the positioning snap structure 361.

[0125] During the assembly process, the lower end of the first shroud 36 can be inserted into the slot provided on the base 31 by using the positioning snap structure 361 to pre-position the first shroud 36, and then the first shroud 36 can be fixed to the middle frame connecting plate 33 or to the first heat pump module 1 and the second heat pump module 2 by using fasteners such as screws. In this way, one end is inserted and positioned, and the other end is fixed by using fasteners. Compared with the solution of fixing both ends by using fasteners, the number of fasteners can be reduced, and the installation operation is simplified.

[0126] As Figure 12 shown, bending structures 362 can also be added to the left and right ends of the first shroud 36, and the bending structures 362 can abut against the first heat pump module 1 and the second heat pump module 2 to enhance the overall structural strength of the first shroud 36.

[0127] As Figure 12 shown, a racetrack-shaped discontinuous stamping hole can also be provided in the middle of the first shroud 36. During the assembly process, a racetrack-shaped notch can be punched in the middle of the first shroud 36 for the total water inlet 441 and the total water outlet 451 of the water supply pipe assembly 4 to be docked with the user-side water circuit system.

[0128] In an exemplary embodiment, as Figure 13 shown, the air source heat pump unit further includes: a second baffle 37, which is fixed to the top of the installation space 34 and covers the top opening of the installation space 34.

[0129] For a working environment with long-term snowfall in some extremely cold regions, a second baffle 37 can be added to the top of the installation space 34. The setting of the second baffle 37 can prevent snow from accumulating too high on the first baffle 35 and blocking the first air-side heat exchanger and the second air-side heat exchanger, thus affecting the heat exchange efficiency. It can also reduce the accumulation of debris between the first air-side heat exchanger and the second air-side heat exchanger.

[0130] Among them, the second baffle 37 can be fixedly connected to the top frame connecting plate 32, or can be fixedly connected to the first heat pump module 1 and the second heat pump module 2.

[0131] For example: connecting vertical plates 371 are respectively provided at the front and rear ends of the second baffle 37, and the connecting vertical plates 371 are fixedly connected to the top frame connecting plate 32 by means of fasteners, welding, etc. A hem can also be provided at the upper end of the connecting vertical plate 371, and the hem can be hung on the upper end of the top frame connecting plate 32.

[0132] The second baffle 37 can also be provided with reinforcing ribs 357 extending along its length direction (i.e., the front and rear direction), which is beneficial to improving its overall structural strength.

[0133] In an exemplary embodiment, the air source heat pump unit further includes: at least one second enclosure 38, as Figure 14 and Figure 15 shown. The second enclosure 38 is connected to the second baffle 37 and covers a part of the side opening of the installation space 34.

[0134] The second enclosure 38 and the third enclosure can further prevent snow from accumulating too high on the first partition and blocking the first air-side heat exchanger and the second air-side heat exchanger, thus affecting the heat exchange efficiency. It can also further reduce the accumulation of debris between the first air-side heat exchanger and the second air-side heat exchanger, and is also beneficial to optimizing the appearance of the unit.

[0135] The number of the second enclosures 38 can be one. For example, only the second enclosure 38 is provided on the front side of the installation space 34, and the rear side of the installation space 34 faces the wall, so the second enclosure 38 can be omitted. The number of the second enclosures 38 can also be two, as Figure 14 and Figure 15 shown. The two second enclosures 38 are arranged front and rear and respectively cover a part of the front and rear openings of the installation space 34. The second enclosure 38 and the first enclosure 36 can be set as an integral structure or a split structure.

[0136] The second enclosure 38 can be connected to the second baffle 37 at the upper end. Or, the second enclosure 38 can also be connected to the top frame connecting plate 32 at the upper end and connected to the middle frame connecting plate 33 at the lower end.

[0137] When the air source heat pump unit further includes a second enclosing plate 38, the second baffle 37 can be fixedly connected to the second enclosing plate 38, and the second enclosing plate 38 is fixedly connected to the top frame connecting plate 32 and the middle frame connecting plate 33.

[0138] In one example, the second enclosing plate 38 is rotatably connected to the second baffle 37, as Figure 15 shown.

[0139] This facilitates rotating and opening the second enclosing plate 38 as needed, and then overhauling the internal structure.
