These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0039] In the description of the embodiments of this application, the technical terms "first," "second," "third," etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0040] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0041] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist.

[0045] In related technologies, HVAC systems include air conditioners, heat pumps, pool machines, and water heaters. An HVAC system comprises multiple indoor units, each equipped with a corresponding electrical control board to control its operation. These control boards require different mounting structures to secure them relative to the outdoor unit's casing. Typically, the mounting structures are individually fixed to the outdoor unit's casing. During the installation of the control boards, one board and its corresponding mounting structure must be fixed first, followed by the installation of another board and its corresponding structure. The installation of the preceding control board may affect the installation process of the subsequent one, thus increasing the difficulty of installation.

[0046] The outdoor unit of this application is equipped with a first electronic control board 300 and a second electronic control board 500. The first electronic control board 300 and the second electronic control board 500 are electrically connected to the main control board 700 to control different indoor units respectively. The first electronic control board 300 is mounted on the end plate 200, and the second electronic control board 500 is mounted on the mounting component 400. The mounting component 400 is mounted on the side of the end plate 200 opposite to the first electronic control board 300. The first electronic control board 300 and the second electronic control board 500 can be assembled outside the housing 100, and then the end plate 200 is installed on the housing 100 to realize the installation of the first electronic control board 300 and the second electronic control board 500. The assembly method is simple, and the assembly process is not limited by the internal space of the housing 100.

[0047] This application proposes to provide a heating, ventilation, and air conditioning system, including a first indoor unit, a second indoor unit, and an outdoor unit.

[0048] For example, taking a heating and ventilation system with refrigerant as the heating medium and water as the heating object, the first indoor unit and the second indoor unit of the heating and ventilation system are both air conditioner indoor units, and the first indoor unit and the second indoor unit form a circulation path with the outdoor unit.

[0049] For example, in a heating, ventilation, and air system where air and water are used as the medium, the first indoor unit of the heating, ventilation, and air system can be an air conditioning indoor unit, and the second indoor unit can be a fresh air indoor unit.

[0050] This application proposes to provide an outdoor unit for use in HVAC systems. Please refer to [link / reference]. Figures 1 to 3 and Figure 5The outdoor unit includes a housing 100, an end plate 200, a first electrical control board 300, a mounting component 400, and a second electrical control board 500. The end plate 200 is installed inside the housing 100 and includes a boss 210 and an end plate body 220 connected to each other. The boss 210 protrudes from the end plate body 220 along a first direction, which is orthogonal to the vertical direction. The first electrical control board 300 is installed on the boss 210 and is used for electrical connection with the first indoor unit. The mounting component 400 is connected to the end plate body 220 and is located along the first direction on the side of the end plate body 220 opposite to the first electrical control board 300. The second electrical control board 500 is installed on the mounting component 400 and is located on the side of the mounting component 400 opposite to the end plate body 220. The second electrical control board 500 is used for electrical connection with the second indoor unit.

[0051] It should be noted that the first direction is a unidirectional direction.

[0052] For example, the second control board 500, mounting component 400, end plate 200, and first control board 300 are all arranged parallel to each other in the thickness direction. Along the thickness direction of the end plate 200, the second control board 500, mounting component 400, end plate 200, and first control board 300 are arranged sequentially. The thickness direction of the end plate 200 is orthogonal to the vertical direction. The vertical direction is as follows... Figure 1 The direction indicated by the middle arrow R1. The thickness direction of end plate 200 is as follows. Figure 4 The direction indicated by the middle arrow R2,

[0053] For example, please refer to Figure 8 The outdoor unit also includes a main control board 700 installed on the housing 100. The first control board 300 and the second control board 500 are both electrically connected to the main control board 700. The main control board 700 is electrically connected to the first indoor unit and the second indoor unit, respectively. The main control board 700 is a communication control board. The first control board 300 can be electrically connected to the first indoor unit through the main control board 700, and the second control board 500 can be electrically connected to the second indoor unit through the main control board 700. The main control board 700 is located on the side of the second control board 500 opposite to the end plate 200.

[0054] In this embodiment, the outdoor unit includes a first control board 300 and a second control board 500. Both the first control board 300 and the second control board 500 can be electrically connected to the corresponding indoor unit via the main control board 700 to achieve control operation. A boss 210 protrudes from the end plate body 220 along a first direction. The first control board 300 is mounted on the boss 210. The boss 210 increases the distance between the first control board 300 and the mounting component 400, thereby reducing interference between them. The installation process of the first control board 300 and the second control board 500 is relatively stable. Furthermore, since both the first control board 300 and the second control board 500 are located in the outdoor unit, the space occupied by the first control board 300 and the second control board 500 in the corresponding indoor unit can be saved. The indoor unit is smaller in size, and when the user installs the indoor unit indoors, the indoor unit only needs to occupy a small installation space.

[0055] In one embodiment, please refer to Figure 8 The housing 100 includes a housing body 110 and a partition 120 connected to each other, with the partition 120 spaced apart from the end plate 200. The partition 120 is located on the side of the end plate 200 opposite to the first electrical control board 300. The partition 120 divides the interior of the housing body 110 into a fan chamber and a compressor chamber, with the end plate 200 located within the compressor chamber. The first electrical control board 300 and the second electrical control board 500 are electrically connected to the main control board 700, which is electrically connected to the first and second indoor units. The main control board 700 is mounted on the partition 120, located between the second electrical control board 500 and the partition 120, with the main control board 700 and the second electrical control board 500 spaced apart.

[0056] In one embodiment, please refer to Figure 8 The housing 100 also includes a side plate 130 and a cover plate (not shown in the figure). The side plate 130 is mounted on the housing body 110, and the end plate 200 is mounted on the side plate 130. The side plate 130 also has an inspection hole 130a. The cover plate is detachably mounted on the side plate 130. When the cover plate is mounted on the side plate 130, the cover plate covers the inspection hole 130a. The inspection hole 130a is located on the side of the first electronic control board 300 opposite to the end plate body 220. The partition plate 120 is arranged at an interval from the side plate 130.

[0057] In one embodiment, please refer to Figure 3The boss 210 and the mounting member 400 form a cavity 210a. The cavity 210a is located on one side of the mounting member 400 along a first direction. The boss 210 has a first mounting hole 210b communicating with the cavity 210a. The first electronic control board 300 includes a first mounting hook 310, which can pass through the first mounting hole 210b to extend into the interior of the cavity 210a. The first mounting hook 310 is engaged with the edge of the first mounting hole 210b. The first electronic control board 300 and the boss 210 are connected by the first mounting hook 310 and the first mounting hole 210b, which enables the first electronic control board 300 to be quickly positioned relative to the end plate 200, increasing assembly efficiency. Furthermore, the cavity 210a can avoid the first mounting hook 310, increasing the engagement depth between the first mounting hook 310 and the first mounting hole 210b. Furthermore, the boss 210 and the first electronic control board 300 can be fixedly connected by screws to increase the connection strength between the first electronic control board 300 and the end plate 200. The cavity 210a can avoid the screws and reduce interference between the screws and the mounting part 400.

[0058] It is understood that other embodiments of this application do not limit the connection form between the first electronic control board 300 and the boss 210. Exemplarily, the boss 210 is a solid structure with threaded holes, and the first electronic control board 300 is fixedly connected to the boss 210 by screws.

[0059] In one embodiment, the first mounting hook 310 includes a hook body and a guide member connected to each other. The first mounting hook 310 can be an integrally formed structure. The hook body is connected to the end plate body 220, and the guide member is located on the side of the hook body away from the end plate body 220. In the top-down direction, the distance between the guide member and the end plate body 220 along the thickness direction of the first end plate 200 gradually increases. For example, the guide member is inclined towards the first end plate 200 from top to bottom. During the installation of the second end plate 200 onto the first end plate 200, the guide member can easily extend from the side of the first end plate 200 into the first mounting hole 210b, so that the first mounting hook 310 aligns with the first mounting hole 210b. This reduces the need for the second end plate 200 to be tilted at a large angle to extend into the first mounting hole 210b, making the installation process of the second end plate 200 and the first end plate 200 simpler and the assembly efficiency higher.

[0060] In one embodiment, please refer to Figure 3 and Figure 6The boss 210 includes a support member 211 and a transition member 212 connected to each other. The boss 210 can be an integrally formed structure, and the transition member 212 is circumferentially arranged around the support member 211. The transition member 212 is connected to the end plate body 220 and the support member 211 respectively. The central axis of the support member 211 is arranged parallel to the central axis of the end plate body 220. The first electrical control board 300 is mounted on the support member 211. Exemplarily, at least a portion of the structure of the first electrical control board 300 is in close contact with the support member 211. The central axis of the support member 211 is arranged parallel to the central axis of the end plate body 220. The support member 211 and the end plate body 220 are basically parallel. When the first mounting plate is mounted on the support member 211, the first mounting plate is also basically parallel to the end plate body 220, thereby reducing the space occupied by the first mounting plate in the thickness direction to a certain extent. The first electrical control board 300 and the end plate 200 are relatively compact and have a high degree of integration. For example, a first mounting hole 210b is formed in the carrier 211.

[0061] For example, the carrier 211, the transition member 212 and the mounting member 400 together form a cavity 210a, with the carrier 211 and the mounting member 400 located on opposite sides of the cavity 210a.

[0062] It is understood that other embodiments of this application are not limited to the arrangement of the central axis of the support member 211 parallel to the central axis of the end plate body 220. Exemplarily, the central axis of the support member 211 is arranged to intersect the central axis of the end plate body 220, that is, the plane in which the support member 211 is located intersects the plane in which the end plate body 220 is located.

[0063] In one embodiment, please refer to Figure 1 The contour line connecting the transition member 212 and the carrier member 211 is the first contour line 212a, and the contour line connecting the transition member 212 and the end plate body 220 is the second contour line 212b. Projected along the thickness direction of the end plate 200, the projection area of ​​the first contour line 212a is located within the projection area of ​​the second contour line 212b. It can be understood that the projection area of ​​the first contour line 212a represents the size of the opening 220e of the cavity 210a facing the carrier member 211, and the projection area of ​​the second contour line 212b represents the size of the opening 220e of the cavity 210a facing the mounting member 400. In the first direction, the size of the opening 220e of the cavity 210a gradually decreases, resulting in a larger connection area between the transition member 212 and the end plate body 220 to provide greater connection strength. The boss 210 is roughly truncated pyramidal in shape, and the overall rigidity of the boss 210 is high. During the operation of the outdoor unit, the amplitude of vibration generated by the boss 210 is small, thereby making the first electrical control board 300 installed on the boss 210 more stable.

[0064] It is understood that other embodiments of this application do not limit the shape of the boss 210. Exemplarily, the boss 210 is a prism.

[0065] In one embodiment, please refer to Figure 3 The end plate body 220 has a second mounting hole 220a, and the mounting member 400 has a second mounting hook 400a facing the end plate body 220. The mounting member 400 is fastened to the edge of the second mounting hole 220a by the second mounting hook 400a. For example, there can be multiple second mounting holes 220a, which are arranged at intervals. The number of second mounting hooks 400a corresponds to the number of second mounting holes 220a, and each second mounting hook 400a is fastened to the edge of a different second mounting hole 220a.

[0066] In the embodiment of this application, the end plate body 220 and the mounting component 400 are connected by a second mounting hook 400a and a second mounting hole 220a. The mounting component 400 can be positioned with the end plate body 220 relatively quickly. The assembly method is simple and does not require additional assembly tools. The assembly efficiency between the mounting component 400 and the end plate body 220 is high.

[0067] It is understood that other embodiments of this application do not limit the assembly method of the end plate body 220 and the mounting component 400.

[0068] In one embodiment, please refer to Figure 3 The second mounting hole 220a includes a guide hole 220b and a receiving hole 220c that are interconnected. The guide hole 220b is located above the receiving hole 220c. The opening 220e of the guide hole 220b gradually decreases in size from top to bottom. The second mounting hook 400a engages with the edge of the receiving hole 220c. During the installation of the mounting component 400 onto the end plate body 220, the second mounting hook 400a can extend from the guide hole 220b into the second mounting hole 220a, and then move downwards to move into the receiving hole 220c. The larger opening 220e of the guide hole 220b reduces the assembly accuracy of the second mounting hook 400a when installing it into the second mounting hole 220a, increases the installation speed of the end plate 200 of the mounting component 400, and improves assembly efficiency.

[0069] It is understandable that the size of the opening 220e of the guide hole 220b refers to the distance between the two hole walls of the guide hole 220b gradually approaching each other from top to bottom along the width direction of the end plate 200. The size of the opening 220e of the receiving hole 220c is equal to the size of the minimum opening 220e of the guide hole 220b. The width direction of the end plate 200 is orthogonal to both the thickness direction and the vertical direction of the end plate 200. The width direction of the end plate 200 is as follows: Figure 1 The direction indicated by the middle arrow R3.

[0070] In one embodiment, please refer to Figure 1 and Figure 2 The end plate body 220 has a cable passage 220d, which extends to the side wall of the end plate body 220 to form an opening 220e. The outdoor unit also includes a first wire connected to the first control board 300 and the main control board 700 respectively. The first wire passes through the cable passage 220d and can exit the cable passage 220d through the opening 220e. The first wire can move into or out of the cable passage 220d through the opening 220e. The outdoor unit also includes a limiting member 600 installed on the end plate body 220. The limiting member 600 is located on the side of the cable passage 220d away from the first control board 300. The limiting member 600 partially extends into the cable passage 220d and is used to prevent the first wire from coming out of the opening 220e. There are multiple cable passages 220d, and each cable passage 220d is provided with a corresponding limiting member 600. The limiting member 600 extends partially into the wire passage 220d and is used to prevent the first wire from detaching from the wire passage 220d. The limiting member 600 restricts the movement of the first wire, reducing the likelihood of it detaching from the wire passage 220d when it passes through it. Furthermore, when the first wire is connected to both the first control board 300 and the first indoor unit, it can move from the opening 220e into the wire passage 220d, thus preventing the limiting member 600 from detaching. The manner in which the first wire enters the wire passage 220d is not limited by the connection status of the first wire to the first control board 300 and the first indoor unit.

[0071] In another embodiment, the end plate body 220 has a wire passage 220d, which is spaced apart from the side wall of the end plate body 220. The wires need to be passed through the wire passage 220d first, so that the first electrical control board 300 is electrically connected to the main control board 700.

[0072] It is understood that other embodiments of this application do not limit whether the outdoor unit is equipped with a limiter 600.

[0073] In one embodiment, please refer to Figure 2 The sidewall of the wire passage 220d facing away from the outlet 220e is curved. The curved surface increases the contact area between the first conductor and the sidewall of the wire passage 220d, reducing wear between them and increasing the service life of the first conductor. For example, the sidewall of the wire passage 220d facing away from the outlet 220e is a circular arc surface.

[0074] For example, please refer to Figure 2The limiting part includes a first stop bar 610 and a second stop bar 620. The first stop bar 610 and the second stop bar 620 are respectively connected to the end plate body 220. The first stop bar 610 and the second stop bar 620 are arranged in the vertical direction and projected along the width direction of the first end plate 200. The projection area of ​​the first stop bar 610 partially overlaps with the projection area of ​​the wire passage 220d, and the projection area of ​​the second stop bar 620 partially overlaps with the projection area of ​​the wire passage 220d.

[0075] In one embodiment, please refer to Figure 3 The end plate body 220 has a flange 220f extending along a first direction. The flange 220f is located above the first electronic control board 300 and is projected in the vertical direction. The projection area of ​​the boss 210 and the projection area of ​​the first electronic control board 300 are located within the projection area of ​​the flange 220f. For example, the flange 220f is formed at the top of the end plate body 220.

[0076] In the embodiment of this application, the end plate body 220 has a flange 220f extending along a first direction. The flange 220f can play a certain role in blocking water from the first electronic control board 300, reducing the possibility of the first electronic control board 300 being short-circuited by external condensation or rainwater. Furthermore, in the event of debris falling above the first electronic control board 300, the flange 220f can block the debris, reducing the possibility of the first electronic control board 300 being damaged by external debris.

[0077] It is understood that other embodiments of this application do not limit whether the end plate body 220 is formed with a flange 220f.

[0078] In one embodiment, please refer to Figure 6 and Figure 7 The end plate body 220 protrudes upward to form a wire clamping portion 220g. The wire clamping portion 220g has a through-hole 220h. The outdoor unit also includes a second wire for connecting to the power supply and the first electronic control board 300. The second wire passes through the through-hole 220h and abuts against the wire clamping portion 220g. The wire clamping portion 220g abuts against the top of the second wire, and the through-hole 220h guides the direction of the second wire and reduces the degree of upward protrusion of the second wire. Furthermore, the wire clamping portion 220g provides some protection for the second wire, reducing the possibility of damage.

[0079] It is understood that other embodiments of this application do not limit whether the end plate body 220 is formed with a pressure line portion 220g.

[0080] For example, referring to the figure, the outdoor unit also includes a fan, evaporator, compressor, outdoor heat exchanger, and expansion valve. The fan, evaporator, compressor, outdoor heat exchanger, and expansion valve are all installed within the housing 100, and these components are sequentially connected via refrigerant pipes. When the HVAC system is operating, the refrigerant in the evaporator absorbs heat from the air, thus becoming a high-temperature, low-pressure gas. This high-temperature gas is then compressed by the compressor, transforming the refrigerant into a high-temperature, high-pressure liquid. This high-temperature, high-pressure liquid exchanges heat with water in the water circulation path through the heat exchanger, raising the water temperature and transforming the refrigerant into a low-temperature, high-pressure liquid. The low-temperature, high-pressure liquid then passes through the expansion valve, becoming a low-temperature, low-pressure gas, which then circulates back to the evaporator, thus completing the refrigerant circulation process.
