[0065] 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0066] The following is for reference. Figures 1-10 Description of outdoor unit 100 according to an embodiment of the present utility model.

[0067] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 The outdoor unit 100 according to the first aspect of the present invention includes an outdoor unit housing 1, an outdoor heat exchanger, an outdoor fan, a compressor assembly 2, a water heat exchange assembly 3, and a liquid storage tank 4.

[0068] The outdoor unit housing 1 has a first chamber 11 and a second chamber 12 arranged in a left-right direction. For example, a partition can be installed inside the outdoor unit housing 1 to divide the space inside the outdoor unit housing 1 into the first chamber 11 and the second chamber 12 arranged in a left-right direction. The outdoor heat exchanger and the outdoor fan are located in the first chamber 11. An air inlet and an air outlet are formed on the outdoor unit housing 1. The air outlet can be formed on the front side of the outdoor unit housing 1, and at least a portion of the air outlet can be formed on the rear side of the outdoor unit housing 1. The first chamber 11 connects the air inlet and the air outlet. When the outdoor fan is working, it drives outside air to enter the first chamber 11 from the air inlet, exchange heat with the outdoor heat exchanger, and then discharge it from the air outlet.

[0069] The compressor assembly 2 is located in the second chamber 12, and the water heat exchange assembly 3 is located in the second chamber 12. The water heat exchange assembly 3 includes a water heat exchanger 31, which has a water flow path and a refrigerant flow path for mutual heat exchange. The water heat exchange assembly 3 may include a water pump, which can be used to drive the water flow in the water flow path, and the compressor assembly 2 is used to drive the refrigerant flow in the refrigerant flow path. The water flow path of the water heat exchanger 31 can be connected to the water pump, and the water can flow into and out of the water heat exchanger 31 under the drive of the water pump. The refrigerant flow path of the water heat exchanger 31 can be connected to the compressor assembly 2, and the refrigerant in the refrigerant flow path can exchange heat with the water flow in the water flow path, thereby realizing the heating and cooling functions of the water flow through the water heat exchanger 31. The water heat exchange assembly 3 can regulate the temperature of the passing water flow, thereby realizing the heating and cooling functions of the entire unit for the water flow. The water flowing out of the water heat exchanger 31 can be delivered to the room to regulate the temperature of the indoor domestic water or to regulate the indoor temperature.

[0070] For example, the outdoor unit 100 may also include a throttling component 61, which may be an electronic expansion valve. The compressor assembly 2, the outdoor heat exchanger, the throttling component 61, and the refrigerant flow path of the water heat exchanger 31 can be connected to form a refrigerant circulation path. During cooling, the refrigerant flowing in the refrigerant flow path of the water heat exchanger 31 can cool the water in the water flow path of the water heat exchanger 31; during heating, the refrigerant flowing in the refrigerant flow path of the water heat exchanger 31 can heat the water in the water flow path of the water heat exchanger 31.

[0071] For example, during cooling, the compressor assembly 2 discharges the compressed refrigerant and flows into the outdoor heat exchanger of the outdoor unit 100. The refrigerant flowing through the outdoor heat exchanger can pass through the throttling device 61 and then flow into the water heat exchanger 31. After heat exchange in the water heat exchanger 31, the refrigerant flows back into the compressor assembly 2 and is compressed again. The liquid receiver 4 can replenish the refrigerant flow path of the water heat exchanger 31 according to actual needs.

[0072] For example, during heating, the compressor assembly 2 discharges the compressed refrigerant and flows into the water heat exchanger 31. After heat exchange in the water heat exchanger 31, the refrigerant can flow through the throttling component 61 and then into the outdoor heat exchanger of the outdoor unit 100. After heat exchange in the outdoor heat exchanger, the refrigerant flows into the compressor assembly 2 and is compressed again.

[0073] With the outdoor heat exchanger and outdoor fan located in the first chamber 11, the compressor assembly 2 in the second chamber 12, the water heat exchange assembly 3 in the second chamber 12, and the liquid storage tank 4 in the second chamber 12, this partitioned design makes maintenance and repair of each component more convenient. Maintenance personnel can selectively open the corresponding chambers for inspection and repair without requiring extensive disassembly of the entire outdoor unit 100. For example, if the outdoor fan malfunctions, only the relevant part of the first chamber 11 needs to be opened for repair, without affecting the compressor assembly 2, water heat exchange assembly 3, or liquid storage tank 4 located in the second chamber 12, significantly shortening maintenance time and improving maintenance efficiency.

[0074] The liquid receiver 4 is located in the second chamber 12 and is used to store refrigerant. The liquid receiver 4 can replenish refrigerant to the refrigerant circulation path of the outdoor unit 100. The liquid receiver 4 and the water circuit heat exchanger 31 are arranged vertically. By arranging the liquid receiver 4 and the water circuit heat exchanger 31 vertically, the space in the vertical direction can be fully utilized, and the liquid receiver 4 and the water circuit heat exchanger 31 can be arranged in an orderly manner, making the overall structure of the liquid receiver 4 and the water circuit heat exchanger 31 compact. This reduces the space occupied by the liquid receiver 4 and the water circuit heat exchanger 31 in the horizontal direction, which is conducive to the layout optimization in the second chamber 12 and realizes the miniaturization of the outdoor unit 100 as a whole.

[0075] According to the embodiment of the present utility model, the outdoor unit 100, by arranging the liquid storage tank 4 and the water heat exchanger 31 in the vertical direction, can make full use of the vertical space inside the outdoor unit casing 1, so that the liquid storage tank 4 and the water heat exchanger 31 are arranged in an orderly manner, and the overall structure of the liquid storage tank 4 and the water heat exchanger 31 is compact, reducing the space occupied by the liquid storage tank 4 and the water heat exchanger 31 in the horizontal direction, which is conducive to the optimization of the component layout in the second chamber 12 and to the miniaturization of the outdoor unit 100 as a whole.

[0076] Reference Figures 4-8 According to some embodiments of the present invention, at least a portion of the projection of the liquid storage tank 4 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane. This can include situations where at least a portion of the projection of the liquid storage tank 4 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane; or, for example, the entire projection of the liquid storage tank 4 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane.

[0077] By ensuring that at least a portion of the projection of the liquid storage tank 4 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane, the projections of the liquid storage tank 4 and the water heat exchanger 31 onto the horizontal plane partially or completely overlap, making their total projected area on the horizontal plane approach the projected area of ​​the water heat exchanger 31 onto the horizontal plane. This effectively compresses the space occupied by the liquid storage tank 4 and the water heat exchanger 31 on the horizontal plane, facilitating layout optimization within the second chamber 12, and thus contributing to the miniaturization of the outdoor unit 100.

[0078] Reference Figures 4-8 According to some embodiments of the present invention, the liquid storage tank 4 and the water heat exchanger 31 are both placed vertically, which can make full use of the space in the vertical direction. The liquid storage tank 4 and the water heat exchanger 31 are stacked using the height space in the second chamber 12, reducing the space occupied by the liquid storage tank 4 and the water heat exchanger 31 in the horizontal direction, thereby effectively reducing the space occupied by the liquid storage tank 4 and the water heat exchanger 31 as a whole in the horizontal direction.

[0079] Reference Figures 4-8 According to some embodiments of this utility model, the water heat exchanger 31 is located below the liquid storage tank 4. Since the water heat exchanger 31 is relatively larger in weight and volume than the liquid storage tank 4, its lower center of gravity and greater stability when positioned below the liquid storage tank 4 make it more stable. In addition, since the liquid storage tank 4 is located above the water heat exchanger 31, the refrigerant in the liquid storage tank 4 can flow into the inlet pipe of the liquid storage tank 4 under its own gravity, facilitating the replenishment of refrigerant.

[0080] Reference Figures 4-8 According to some embodiments of the present invention, the outdoor unit housing 1 includes a chassis 13, and the water heat exchanger 31 is installed on the chassis 13. This can lower the center of gravity of the water heat exchanger 31, making its center of gravity close to the bottom of the outdoor unit 100. This can enhance the installation stability of the water heat exchanger 31 on the outdoor unit housing 1, and can also effectively reduce the amplitude and frequency of vibration of the water heat exchanger 31 during operation, thereby effectively reducing the noise generated by the vibration of the water heat exchanger 31.

[0081] For example, a partition is provided between the first chamber 11 and the second chamber 12. If the water heat exchanger 31 is installed on the partition between the first chamber 11 and the second chamber 12, the center of gravity of the water heat exchanger 31 will be located in the middle of the outdoor unit 100 in the height direction. When the outdoor unit 100 is running, the vibration inertia moment of the water heat exchanger 31 will be large, and the noise generated by the vibration of the water heat exchanger 31 will be large. By installing the water heat exchanger 31 on the chassis 13, the height of the center of gravity of the water heat exchanger 31 in the height direction can be effectively reduced, thereby effectively reducing the vibration inertia moment of the water heat exchanger 31 when the outdoor unit 100 is running, and thus reducing the noise generated by the vibration of the water heat exchanger 31 during operation.

[0082] Reference Figures 4-8 According to some embodiments of this utility model, the water heat exchanger 31 is detachably mounted on the chassis 13. The detachable connection between the water heat exchanger 31 and the chassis 13 makes maintenance or replacement of the water heat exchanger 31 more convenient. For example, when the water heat exchanger 31 needs maintenance or replacement, it can be removed from the chassis 13 and moved to a larger space for inspection, making maintenance or replacement of the water heat exchanger 31 more convenient.

[0083] Reference Figures 4-8 According to some embodiments of the present invention, the bottom of the water heat exchanger 31 is provided with a first mounting bracket 311. The water heat exchanger 31 is mounted on the chassis 13 through the first mounting bracket 311, which facilitates the assembly of the water heat exchanger 31 on the chassis 13. The first mounting bracket 311 can also play a positioning role in the assembly of the water heat exchanger 31 on the chassis 13, so that the assembly position of the water heat exchanger 31 on the chassis 13 is more accurate.

[0084] For example, the first mounting bracket 311 is welded to the water heat exchanger 31, which makes the connection between the water heat exchanger 31 and the first mounting bracket 311 simple and has strong stability.

[0085] Reference Figures 4-8 According to some embodiments of the present invention, the bottom surface of the water heat exchanger 31 is spaced apart from the chassis 13 in the vertical direction, which can reduce the vibration of the compressor assembly 2 from being transmitted to the water heat exchanger 31 through the chassis 13 and affecting the water heat exchanger 31. In addition, there may be condensate or other water accumulation on the chassis 13, which can prevent the bottom of the water heat exchanger 31 from contacting the water on the chassis 13 and affecting the water heat exchanger 31.

[0086] Reference Figures 4-8 According to some embodiments of this utility model, the first mounting bracket 311 includes multiple sub-brackets 3112, which are arranged at intervals along the circumference of the water heat exchanger 31. Each sub-bracket 3112 is connected to the chassis 13. The multiple sub-brackets 3112 arranged at intervals along the circumference of the water heat exchanger 31 can form a multi-point support structure, thereby enhancing the support effect of the first mounting bracket 311 on the water heat exchanger 31 and thus improving the stability of the water heat exchanger 31 fixed on the chassis 13. For example, the supporting force of the first mounting bracket 311 on the water heat exchanger 31 can be evenly distributed along the circumference of the water heat exchanger 31, reducing local deformation caused by excessive force at a single point on the water heat exchanger 31.

[0087] For example, each sub-bracket 3112 is connected to the chassis 13 by fasteners, making the connection between the sub-bracket 3112 and the chassis 13 simple and highly stable.

[0088] In the description of this utility model, "multiple" means two or more.

[0089] Reference Figures 4-8 According to some embodiments of this utility model, each sub-support 3112 has a support portion 3113 on its bottom surface. The support portion 3113 is supported on the chassis 13, and a first fastener connects the support portion 3113 and the chassis 13. The support portion 3113 and the chassis 13 are connected by the first fastener, making the connection between the sub-support 3112 and the chassis 13 simple and highly stable. By connecting the support portion 3113 and the chassis 13, the connection between the sub-support 3112 and the chassis 13 can be realized, thereby realizing the connection between the water heat exchanger 31 and the chassis 13.

[0090] Reference Figures 4-8 According to some embodiments of the present invention, the chassis 13 is provided with a positioning groove, and at least some of the support portions 3113 of the sub-supports 3112 are inserted into the positioning groove. The insertion of at least some of the support portions 3113 of the sub-supports 3112 into the positioning groove can include the following situations: for example, some of the support portions 3113 of the sub-supports 3112 may be inserted into the positioning groove; or, for another example, all the support portions 3113 of the sub-supports 3112 may be inserted into the positioning groove.

[0091] Since the chassis 13 is provided with a positioning groove, it can play a positioning role in the assembly of at least some of the sub-supports 3112 on the chassis 13, ensuring that the assembly position of at least some of the sub-supports 3112 on the chassis 13 is accurate; and, by inserting the support part 3113 of at least some of the sub-supports 3112 into the positioning groove, the overall structure of at least some of the sub-supports 3112 and the chassis 13 can also be made compact.

[0092] Reference Figures 4-8 According to some embodiments of this utility model, a replenishment pipe 41 is connected to the bottom of the storage tank 4. The water heat exchanger 31 has a first refrigerant port 312 and a second refrigerant port 314. One of the first refrigerant port 312 and the second refrigerant port 314 serves as a refrigerant inlet and the other as a refrigerant outlet. The refrigerant flow path connects the first refrigerant port 312 and the second refrigerant port 314. The first refrigerant port 312 is connected to a first refrigerant pipe 313. The replenishment pipe 41 is connected to and communicates with the first refrigerant pipe 313. By connecting the first refrigerant pipe 313 to the first refrigerant port 312 and the replenishment pipe 41 to and communicating with the first refrigerant pipe 313, the refrigerant stored in the storage tank 4 can flow into the water heat exchanger 31 through the first refrigerant pipe 313 and the first refrigerant port 312, thus meeting the refrigerant demand of the water heat exchanger 31 in a timely manner.

[0093] For example, the outdoor unit 100 may also include a throttling component 61, which may be an electronic expansion valve. The compressor assembly 2, the outdoor heat exchanger, the throttling component 61, and the refrigerant flow path of the water heat exchanger 31 can be connected to form a refrigerant circulation path. During cooling, the refrigerant flowing in the refrigerant flow path of the water heat exchanger 31 can cool the water in the water flow path of the water heat exchanger 31; during heating, the refrigerant flowing in the refrigerant flow path of the water heat exchanger 31 can heat the water in the water flow path of the water heat exchanger 31.

[0094] For example, during cooling, the refrigerant circulation path is as follows: the compressor assembly 2 discharges the compressed refrigerant and flows into the outdoor heat exchanger of the outdoor unit 100. The refrigerant flowing through the outdoor heat exchanger can pass through the throttling component 61, and then flow into the water heat exchanger 31 through the first refrigerant port 312. After heat exchange in the water heat exchanger 31, the refrigerant flows into the compressor assembly 2 through the second refrigerant port 314 and is compressed again. The refrigerant stored in the liquid receiver 4 can be replenished to the refrigerant flow path of the water heat exchanger 31 through the first refrigerant pipe 313 and the first refrigerant port 312 according to actual needs.

[0096] Reference Figures 5-9 According to some embodiments of this utility model, a transition plate 5 is included. The upper and lower ends of the transition plate 5 are respectively connected to the liquid storage tank 4 and the water heat exchanger 31. The transition plate 5 can serve as a connecting carrier between the liquid storage tank 4 and the water heat exchanger 31. By connecting the liquid storage tank 4 and the water heat exchanger 31 through the upper and lower ends of the transition plate 5, the connection between the liquid storage tank 4 and the water heat exchanger 31 is more convenient. Moreover, the dimensions of the transition plate 5 itself in the vertical direction can be used to realize the layered arrangement of the liquid storage tank 4 and the water heat exchanger 31 in the vertical direction.

[0097] Reference Figures 5-9 According to some embodiments of this utility model, the water heat exchanger 31 is provided with a first connecting bracket 315, the liquid storage tank 4 is provided with a second connecting bracket 42, and the upper and lower ends of the adapter plate 5 are respectively connected to the first connecting bracket 315 and the second connecting bracket 42. By connecting the upper and lower ends of the adapter plate 5 to the first connecting bracket 315 and the second connecting bracket 42 respectively, the connection between the adapter plate 5 and the liquid storage tank 4 and the water heat exchanger 31 can be realized.

[0098] Reference Figures 5-9According to some embodiments of this utility model, the first connecting bracket 315 is disposed on the top of the water heat exchanger 31, and the second connecting bracket 42 is disposed on the top of the storage tank 4. For example, the lower end of the adapter plate 5 can be connected to the water heat exchanger 31, and the upper end of the adapter plate 5 can be connected to the storage tank 4. By disposing of the first connecting bracket 315 on the top of the water heat exchanger 31, the first connecting bracket 315 can fix and support the adapter plate 5, and can also shorten the connection path between the adapter plate 5 and the water heat exchanger 31, reducing the stress loss in the intermediate links. Furthermore, by disposing of the second connecting bracket 42 on the top of the storage tank 4, the height dimension of the adapter plate 5 itself in the vertical direction can be used to realize the layered arrangement of the storage tank 4 and the water heat exchanger 31 in the vertical direction.

[0099] Reference Figures 4-8 According to some embodiments of the present invention, the first connecting bracket 315 is welded and fixed to the water heat exchanger 31, so that the connection between the first connecting bracket 315 and the water heat exchanger 31 is simple and has strong stability.

[0100] Reference Figures 4-8 According to some embodiments of the present invention, the second connecting bracket 42 is welded and fixed to the liquid storage tank 4, which makes the connection between the second connecting bracket 42 and the liquid storage tank 4 simple and has strong stability.

[0101] Reference Figures 4-8 According to some embodiments of this utility model, the adapter plate 5 can be detachably connected to both the first connecting bracket 315 and the second connecting bracket 42, making it more convenient to maintain or replace the liquid storage tank 4 or the water heat exchanger 31. For example, when one of the liquid storage tank 4 and the water heat exchanger 31 needs maintenance or replacement, the relative fixation between the liquid storage tank 4 and the water heat exchanger 31 can be separated by disconnecting the adapter plate 5 from the first connecting bracket 315 or the second connecting bracket 42. This facilitates the maintenance or replacement of one of the liquid storage tank 4 and the water heat exchanger 31 without affecting the other one, greatly shortening the maintenance time and improving maintenance efficiency.

[0102] Reference Figures 7-9 According to some embodiments of the present invention, a second fastener is connected between the adapter plate 5 and the first connecting bracket 315, which makes the connection between the adapter plate 5 and the first connecting bracket 315 simple and has strong stability.

[0103] Reference Figures 7-9 According to some embodiments of the present invention, a third fastener is connected between the adapter plate 5 and the second connecting bracket 42, which makes the connection between the adapter plate 5 and the second connecting bracket 42 simple and has strong stability.

[0104] Reference Figures 7-9 According to some embodiments of this utility model, one of the adapter plate 5 and the first connecting bracket 315 is provided with a first hook 54, and the first hook 54 is hung on the other of the adapter plate 5 and the first connecting bracket 315. By hanging the first hook 54 on the other of the adapter plate 5 and the first connecting bracket 315, the connection between the adapter plate 5 and the first connecting bracket 315 can be simplified and has strong stability.

[0105] Reference Figures 7-9 According to some embodiments of this utility model, one of the adapter plate 5 and the second connecting bracket 42 is provided with a second hook 421, and the second hook 421 is hung on the other of the adapter plate 5 and the second connecting bracket 42. By hanging the second hook 421 on the other of the adapter plate 5 and the second connecting bracket 42, the connection between the adapter plate 5 and the second connecting bracket 42 can be simplified and has strong stability.

[0106] Reference Figures 7-9 According to some embodiments of this utility model, the water heat exchanger 31 is located below the liquid storage tank 4, the first connecting bracket 315 is located on the top of the water heat exchanger 31, and the second connecting bracket 42 is located on the top of the liquid storage tank 4. Since the water heat exchanger 31 is relatively larger in weight and volume than the liquid storage tank 4, its arrangement below the liquid storage tank 4 results in a lower center of gravity and greater stability. In addition, since the liquid storage tank 4 is located above the water heat exchanger 31, the refrigerant in the liquid storage tank 4 can flow into the liquid inlet pipe of the liquid storage tank 4 under its own gravity, which facilitates the replenishment of refrigerant.

[0107] The adapter plate 5 has a first hook 54 at its lower end, which is attached to the top of the first connecting bracket 315. The second connecting bracket 42 has a second hook 421 at its upper end, which is attached to the top of the adapter plate 5. By directly attaching the first hook 54 at the lower end of the adapter plate 5 to the top of the first connecting bracket 315, a snap-fit ​​connection between the adapter plate 5 and the first connecting bracket 315 can be achieved, making the connection between them relatively convenient. Similarly, by directly attaching the second hook 421 at the upper end of the second connecting bracket 42 to the top of the adapter plate 5, a snap-fit ​​connection between the adapter plate 5 and the second connecting bracket 42 can be achieved, making the connection between the adapter plate 5 and the second connecting bracket 42 relatively convenient.

The first positioning notch 3151 can play a positioning role in the assembly between the adapter plate 5 and the first connecting bracket 315, ensuring that the assembly position between the adapter plate 5 and the first connecting bracket 315 is accurate.

[0109] Reference Figures 7-9 According to some embodiments of the present invention, the top of the adapter plate 5 is provided with a second positioning notch 55, and part of the second hook 421 is accommodated in the second positioning notch 55. The second positioning notch 55 can play a positioning role in the assembly between the adapter plate 5 and the second connecting bracket 42, ensuring that the assembly position between the adapter plate 5 and the second connecting bracket 42 is accurate.

[0110] Reference Figures 4-6 According to some embodiments of this utility model, a throttling component 61 is included. The throttling component 61 is located in the second chamber 12 and is connected between the water heat exchanger 31 and the outdoor heat exchanger. The throttling component 61 is fixed to the adapter plate 5. By fixing the throttling component 61 to the adapter plate 5, the adapter plate 5 can provide a certain degree of support and fixation for the throttling component 61, making the throttling component 61 more stably installed inside the outdoor unit 100, reducing the vibration of the throttling component 61 during operation, and thus reducing the noise generated by the vibration of the throttling component 61.

[0111] Among them, the throttling component 61 can be an electronic expansion valve.

[0112] Reference Figures 4-6 According to some embodiments of the present invention, the throttling component 61 is fixed to the adapter plate 5 by a first binding strap. The first binding strap can realize the fixed connection between the throttling component 61 and the adapter plate 5, so that the adapter plate 5 can provide a certain support and fixation for the throttling component 61, thereby enhancing the stability of the throttling component 61 in the outdoor unit 100. Moreover, the first binding strap can simplify the assembly between the throttling component 61 and the adapter plate 5. For example, during the assembly process, it is only necessary to place the throttling component 61 and the adapter plate 5 in a preset position and then bind and fix them with the first binding strap. No complicated installation tools and processes are required, which reduces the assembly difficulty.

[0113] Reference Figure 4 , Figure 5 , Figure 6 and Figure 9According to some embodiments of the present invention, the adapter plate 5 includes an adapter plate body 51 and a fixing part 52. The upper and lower ends of the adapter plate body 51 are respectively connected to the liquid storage tank 4 and the water heat exchanger 31. The fixing part 52 is bent relative to the adapter plate body 51 toward the direction close to the throttling component 61. A first binding groove 521 is formed on the fixing part 52. A first binding strap is passed through the first binding groove 521 to bind and fix the throttling component 61 to the fixing part 52. The upper and lower ends of the adapter plate body 51 are connected to the liquid storage tank 4 and the water heat exchanger 31, respectively. The fixing part 52 is bent relative to the adapter plate body 51 towards the direction close to the throttling component 61, which can make the distance between the fixing part 52 and the throttling component 61 closer, thus making it easier to fix the adapter plate 5 and the throttling component 61. In addition, the first binding groove 521 formed on the fixing part 52 can provide assembly space for the first binding strap, making it easy for the first binding strap to be inserted therein to fix the throttling component 61 to the adapter plate 5, reducing the assembly difficulty.

[0114] Reference Figure 9 According to some embodiments of the present invention, a reinforcing structure 53 is formed on the adapter plate 5, which can enhance the structural strength of the adapter plate 5 to a certain extent and reduce the possibility of deformation of the adapter plate 5.

[0115] Reference Figure 9 According to some embodiments of the present invention, at least a portion of the reinforcing structure 53 extends in the vertical direction. This vertical extension of the reinforcing structure 53 can include, for example, a portion of the reinforcing structure extending in the vertical direction; or, for example, all of the reinforcing structure 53 extending in the vertical direction.

[0116] By extending at least partially the reinforcing structure 53 in the vertical direction, and since the upper and lower ends of the adapter plate 5 are respectively connected to the liquid storage tank 4 and the water heat exchanger 31, the structural strength of the adapter plate 5 can be enhanced in the vertical direction, reducing the possibility of deformation of the adapter plate 5 in the vertical direction.

[0117] Reference Figure 9 According to some embodiments of the present invention, a portion of the adapter plate 5 is recessed along one side of its thickness direction to form at least a portion of the reinforcing structure 53. The ridge or groove (such as a V-shaped or U-shaped cross-section) formed by the recess along one side of the thickness direction of the portion of the adapter plate 5 improves the structural strength and deformation resistance of the adapter plate 5 by changing the moment of inertia of the cross-section, reducing the possibility of deformation of the adapter plate 5. Moreover, compared to adding an additional reinforcing structure 53 to the adapter plate 5, it is not necessary to increase the material thickness of the adapter plate 5 itself. For example, it can be formed in one step by a stamping die, making the processing and manufacturing of the adapter plate 5 more convenient.

[0118] Reference Figures 3-6According to some embodiments of the present invention, at least a portion of the projection of the adapter plate 5 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane. This can include situations where at least a portion of the projection of the adapter plate 5 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane; or, for example, the entire projection of the adapter plate 5 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane.

[0119] By ensuring that at least a portion of the projection of the adapter plate 5 onto the horizontal plane lies within the projection of the water heat exchanger 31 onto the horizontal plane, the projections of the adapter plate 5 and the water heat exchanger 31 onto the horizontal plane partially or completely overlap, making their total projected area on the horizontal plane approach the projected area of ​​the water heat exchanger 31 onto the horizontal plane. This effectively compresses the space occupied by the adapter plate 5 and the water heat exchanger 31 on the horizontal plane, facilitating layout optimization within the second chamber 12, and thus contributing to the miniaturization of the outdoor unit 100.

[0120] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10 According to some embodiments of this utility model, a wire binding plate 316 is provided on the outer wall of the water heat exchanger 31, and some wires are routed along the wire binding plate 316. The wire binding plate 316 can limit some of the wires, so that some of the wires are arranged in a preset direction, avoiding some of the wires from getting tangled together inside the outdoor unit housing 1 or interfering with other components inside the outdoor unit housing 1.

[0121] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10 According to some embodiments of this utility model, a wiring groove 3161 extending in the vertical direction is defined within the wire binding plate 316, and the wire harness running along the wire binding plate 316 is accommodated within the wiring groove 3161. By accommodating the wire harness running along the wire binding plate 316 within the wiring groove 3161, the overall structure of the wire harness and the wire binding plate 316 can be made compact, reducing the space occupied by the wire harness outside the wire binding plate 316.

[0122] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10According to some embodiments of the present invention, the wire harness running along the binding plate 316 is fixed to the binding plate 316 by the second binding strap. The second binding strap can fix the wire harness running along the binding plate 316, so that the wire harness running along the binding plate 316 is fixed at a preset position on the binding plate 316, avoiding the wire harness from getting tangled together. In addition, the second binding strap can make the assembly between the wire harness and the binding plate 316 simpler. For example, in the assembly process, it is only necessary to place the wire harness and the binding plate 316 according to the preset position and then use the second binding strap to tie and fix them. No complicated installation tools and processes are required, which reduces the assembly difficulty.

[0123] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10 According to some embodiments of this utility model, the wire binding plate 316 is detachably connected to the water heat exchanger 31, making the maintenance or replacement of the wire harness or the water heat exchanger 31 more convenient. For example, when the wire harness or the water heat exchanger 31 running along the wire binding plate 316 needs to be repaired or replaced, the wire binding plate 316 can be disconnected from the water heat exchanger 31, thus separating the relative fixation between the wire harness running along the wire binding plate 316 and the water heat exchanger 31. This facilitates the maintenance or replacement of one of the wire harness or the water heat exchanger 31 running along the wire binding plate 316 without affecting the other of the wire harness or the water heat exchanger 31, greatly shortening the maintenance time and improving the maintenance efficiency.

[0124] Reference Figure 4 , Figure 5 , Figure 6 and Figure 10 According to some embodiments of this utility model, a third connecting bracket 317 is welded to the outer wall of the water heat exchanger 31. The wire binding plate 316 includes a wire binding part 3162 and a connecting part 3163. The connecting part 3163 is connected to the third connecting bracket 317 through a fourth fastener. The wire binding part 3162 is used for wire harness routing. The third connecting bracket 317 is welded to the outer wall of the water heat exchanger 31, which makes the connection between the third connecting bracket 317 and the water heat exchanger 31 simple and has strong stability. The connecting part 3163 is connected to the third connecting bracket 317 through the fourth fastener, which makes the connection between the third connecting bracket 317 and the wire binding plate 316 simple and has strong stability. The connection between the wire binding plate 316 and the water heat exchanger 31 is realized by connecting the connecting part 3163 to the third connecting bracket 317 fixed to the outer wall of the water heat exchanger 31.

[0125] Reference Figure 3According to some embodiments of the present invention, the water heat exchanger 31 is located behind the compressor assembly 2, which can make full use of the space in the front-to-back direction, so that the water heat exchanger 31 and the compressor assembly 2 are arranged in an orderly manner, which is conducive to the layout optimization in the second chamber 12.

[0126] Reference Figure 3 According to some embodiments of the present invention, at least a portion of the water heat exchanger 31 is offset from the compressor assembly 2 in the front-rear direction. This offsetting of at least a portion of the water heat exchanger 31 from the compressor assembly 2 in the front-rear direction can include the following situations: for example, a portion of the water heat exchanger 31 may be offset from the compressor assembly 2 in the front-rear direction; or, for another example, the entire water heat exchanger 31 may be offset from the compressor assembly 2 in the front-rear direction.

[0127] By offsetting at least a portion of the water heat exchanger 31 from the compressor assembly 2 in the front-rear direction, a larger operating space can be provided between the water heat exchanger 31 and the compressor assembly 2. For example, it can accommodate disassembly and assembly tools to facilitate the removal or assembly of the water heat exchanger 31 or the compressor assembly 2 in the outdoor unit casing 1. It can also prevent interference between the water heat exchanger 31 and the compressor assembly 2 when one of them is being removed or assembled.

[0128] Reference Figures 4-8 According to some embodiments of this utility model, a water temperature sensor 62 is included. The water temperature sensor 62 is installed in a water heat exchanger 31 and is used to detect the inlet or outlet water temperature of the water heat exchanger 31. The water temperature sensor 62 is in the shape of a long tube, and the angle between the central axis of the water temperature sensor 62 and the horizontal plane is less than 30°. For example, the angle between the central axis of the water temperature sensor 62 and the horizontal plane can be 0°, 10°, 15°, 20°, 30°, etc. By making the angle between the central axis of the water temperature sensor 62 and the horizontal plane less than 30°, the long tube shape of the water temperature sensor 62 can increase the contact area with the water flow, thereby improving the detection speed and accuracy of the water temperature sensor 62 and improving its detection efficiency.

[0129] For example, the water heat exchanger 31 has a first refrigerant port 312 and a second refrigerant port 314. One of the first refrigerant port 312 and the second refrigerant port 314 serves as the refrigerant inlet and the other serves as the refrigerant outlet. The water temperature sensor 62 includes two sensors, which are arranged at intervals along the vertical direction of the water heat exchanger 31. One water temperature sensor 62 is close to the refrigerant inlet and is used to detect the inlet water temperature of the water heat exchanger 31, while the other water temperature sensor 62 is close to the refrigerant outlet and is used to detect the outlet water temperature of the water heat exchanger 31. By placing the two water temperature sensors 62 close to the refrigerant inlet or the refrigerant outlet respectively, the accuracy of the measured inlet water temperature or outlet water temperature can be improved.

[0130] Reference Figures 4-8 According to some embodiments of this utility model, the water temperature sensor 62 includes a detection tube 621 and a temperature detection probe. One end of the detection tube 621 is closed and the other end is open. The temperature detection probe is connected to the open side of the detection tube 621. The detection tube 621 is connected to the water heat exchanger 31 and communicates with the water flow path. The open end of the detection tube 621 facilitates the connection of the temperature detection probe to the detection tube 621 to detect the outlet water temperature or the inlet water temperature.

[0131] The detection tube 621 is a long tube, and the angle between the central axis of the detection tube 621 and the horizontal plane is less than 30°. This allows the temperature detection probe to be connected to one end of the detection tube 621 in the left-right direction, resulting in a larger assembly space. This facilitates the connection between the temperature detection probe and the detection tube 621 and reduces the assembly difficulty.

[0132] For example, instead of having the open end of the detection tube 621 facing downwards, by making the angle between the central axis of the detection tube 621 and the horizontal plane less than 30°, the temperature detection probe can be connected to one end of the detection tube 621 in the left-right direction, which makes the assembly space larger and facilitates the connection between the thermometer detection probe and the detection tube 621.

[0133] For example, if the open end of the detection tube 621 is facing upwards, external rainwater or condensate accumulated on the surface of the water heat exchanger 31 can easily fall into the detection tube 621 under its own gravity, affecting the accuracy of the outlet or inlet water temperature measured by the temperature detection probe. By ensuring that the angle between the central axis of the detection tube 621 and the horizontal plane is less than 30°, the possibility of external rainwater or condensate accumulated on the surface of the water heat exchanger 31 falling into the detection tube 621 under its own gravity can be effectively reduced or avoided, making the outlet or inlet water temperature measured by the temperature detection probe more accurate.

[0134] Reference Figures 3-5 According to some embodiments of the present invention, the bottom surface of the compressor assembly 2 is provided with a second mounting bracket 21. The second mounting bracket 21 includes mounting legs 211 arranged at intervals along the circumference of the compressor assembly 2. The mounting legs 211 arranged at intervals along the circumference of the compressor assembly 2 can provide multi-point support for the compressor assembly 2, which can enhance the support effect of the second mounting bracket 21 on the compressor assembly 2, thereby enhancing the stability of the compressor assembly 2 fixed in the outdoor housing 1.

[0135] The water heat exchanger 31 and the compressor assembly 2 are arranged in a front-to-back direction. Some mounting feet 211 are located on the side of the compressor assembly 2 closest to the water heat exchanger 31, and some mounting feet 211 are located on one side in the left-right direction of the water temperature sensor 62. While multiple mounting feet 211 provide multi-point support for the compressor assembly 2, the mounting feet 211 can be staggered from the water heat exchanger 31 and the water temperature sensor 62 to facilitate the removal or installation of the compressor assembly 2. For example, removal tools can be inserted vertically and aligned with the position of the mounting feet 211 without interfering with the water heat exchanger 31 and the water temperature sensor 62.

[0136] Reference Figures 4-8 According to some embodiments of this utility model, the water heat exchanger 31 is a shell-and-tube heat exchanger. Compared with plate heat exchangers, shell-and-tube heat exchangers are less expensive, which helps to reduce the manufacturing cost of the outdoor unit 100. Furthermore, plate heat exchangers are more likely to be clogged by scale, while shell-and-tube heat exchangers are less likely to be clogged by scale, which can reduce after-sales costs.
