Description

Technical Field

[0001] This application relates to the field of heating, ventilation and air conditioning equipment technology, and in particular to an air conditioning unit and heating, ventilation and air conditioning equipment having the air conditioning unit. Background Technology

[0002] Air conditioning units, as important temperature control devices, are widely used in various places. An air conditioning unit generally consists of an outdoor unit and an indoor unit. Refrigerant is transported between the outdoor and indoor units via pipes connected by interfaces, enabling heat transfer between the indoor and outdoor areas. These interfaces ensure that the refrigerant circulates among key components such as the compressor, condenser, and evaporator, allowing the air conditioning unit to function properly for cooling or heating.

[0003] In traditional designs, these interfaces are typically arranged in a regular pattern. This arrangement presents certain problems in practical applications. When multiple interfaces need to connect to water or gas pipes in the same direction, the later-connected pipe may be obstructed by the previous one, requiring additional pipe layout space or the use of extra fittings to avoid obstruction, thus increasing installation costs and difficulty. Utility Model Content

[0004] This application provides an air conditioning unit and HVAC equipment that can reduce the space required for pipe layout, eliminate the need for additional pipe fittings, facilitate installation, and save installation costs.

[0005] To achieve the above objectives, a first aspect of this application provides an air conditioning unit, including a casing and at least two interfaces; the casing includes a pipe wall; the at least two interfaces are disposed on the pipe wall of the casing for one-to-one connection with at least two pipes, any two interfaces are staggered in a first direction so that the at least two pipes do not interfere with each other on the pipe wall, and in a second direction, adjacent interfaces have a clearance distance, wherein the first direction is the same outlet direction of the at least two interfaces, and the second direction is perpendicular to the first direction.

[0006] In some implementations, the at least two interfaces are not on the same straight line in the second direction.

[0007] In some implementations, the at least two interfaces are on the same straight line in the second direction.

[0008] In some implementations, in the second direction, the center distance L between two adjacent interfaces satisfies: L≥D1+D2;

[0009] Wherein, D1 and D2 represent the diameters of two adjacent interfaces, respectively.

[0010] In some implementations, the center distance between any two adjacent interfaces is equal in the second direction.

[0011] In some embodiments, the interface includes a mounting base and a connecting post connected to the mounting base, the mounting base being mounted on the chassis, and the connecting post being used to connect the pipe.

[0012] In some embodiments, the outer periphery of the connecting post is provided with connecting threads.

[0013] In some embodiments, the interface further includes a valve connected to the connecting post for opening or closing the interface.

[0014] In some embodiments, the interface further includes an identification section disposed on the mounting base for distinguishing interfaces with different functions.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0028] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0029] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0030] 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 belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Generally, air conditioning units typically have multiple interfaces on the outer wall of the casing for connecting pipes to facilitate the transmission of gas or liquid.

[0032] In traditional designs, these interfaces are often arranged in a regular pattern. When connecting pipes, because the interfaces are arranged in rows or columns, if a previous pipe is already connected, the subsequent pipe will be blocked when connecting to it, even if the previous pipe is already connected. To avoid this obstruction and ensure a smooth connection, the subsequent pipe often needs to be increased in height or additional fittings need to be used to avoid the obstruction.

[0033] In one case, such as Figure 1 As shown, the side of chassis 1 has four interfaces, and the four pipes connected to these interfaces face in one direction (extending inwards from the plane perpendicular to the drawing in the diagram). Along the direction of pipe 3, every two interfaces are arranged in a straight line. When connecting pipe 3, the latter two pipes 3 need to be increased in height to avoid obstruction, thus increasing the space required for pipe 3 layout. In some space-constrained locations, such as small computer rooms or narrow equipment rooms, this increased space requirement may lead to installation difficulties or even prevent normal installation. In another case, such as... Figure 2 As shown, in the orientation of pipe 3 (extending from left to right in the diagram), every two interfaces are arranged in a straight line. When connecting pipe 3, the latter two pipes 3 require additional fittings and connecting materials (such as elbows) to avoid obstacles, which not only increases the complexity of installation but also increases the installation cost.

[0034] In response, this application provides an air conditioning unit and HVAC equipment that can reduce the space required for pipe layout, eliminate the need for additional pipe fittings, facilitate installation, and save installation costs.

[0035] Specifically, please refer to Figures 3 to 5 , Figure 3 This is a schematic diagram of the structure of the air conditioning unit provided in this embodiment; Figure 4 This is a structural schematic diagram of the air conditioning unit provided in this embodiment from another perspective; Figure 5 This is a schematic diagram of the structure of the HVAC equipment provided in this embodiment.

[0036] The HVAC equipment in this embodiment includes an air conditioning unit and pipes 3. The air conditioning unit can be an outdoor unit or an indoor unit. The air conditioning unit includes a refrigeration cycle module, which may include components such as a fan, air filter, compressor, condenser, expansion valve, and evaporator. During the refrigeration cycle, the fan of the indoor unit operates, drawing in hot indoor air from the return air inlet. After being filtered by the air filter, the hot air flows through the evaporator. In the evaporator, the low-temperature, low-pressure liquid refrigerant evaporates and absorbs heat, lowering the air temperature before being sent back indoors through the air outlet. The refrigerant then becomes gaseous. Subsequently, the gaseous refrigerant is transported to the outdoor unit through a connecting pipe. In the outdoor unit, the compressor compresses it into a high-temperature, high-pressure gaseous state, which then enters the condenser. Under the action of the fan, the outdoor air carries away the heat from the refrigerant, cooling it into a liquid state. The liquid refrigerant then passes through the expansion valve for throttling and pressure reduction, becoming a low-temperature, low-pressure gas-liquid mixture. It then returns to the indoor unit evaporator through the pipe, starting the next refrigeration cycle.

[0037] The air conditioning unit in this embodiment also includes a casing 1. The refrigeration cycle module is disposed inside the casing 1. The casing 1 includes a pipe wall 11. It can be understood that the casing 1 can be a square casing enclosed by six outer walls, and the pipe wall 11 is one of the six outer walls. At least two interfaces 2 are provided on the pipe wall 11 of the casing 1, and the at least two interfaces 2 are connected one-to-one with at least two pipes 3. For example, the air conditioning unit includes an outdoor unit and an indoor unit, each with its own casing 1. Multiple interfaces 2 on the outdoor unit are connected one-to-one with multiple interfaces 2 on the indoor unit through multiple pipes 3, thereby realizing the transfer of liquid or gas between the outdoor unit and the indoor unit, thus ensuring the normal operation of the HVAC equipment. The pipes 3 can be water pipes or gas pipes, and can be made of materials such as metal pipes or plastic pipes.

[0038] The chassis 1 can be made of metal, such as stainless steel or aluminum alloy, providing sufficient strength and stability to protect the internal air conditioning components, including the compressor, condenser, expansion valve, and evaporator, from external environmental influences. The shape of the chassis 1 can be designed according to actual needs, commonly including cuboids and cubes. The dimensions of the chassis 1 can be determined based on the air conditioning unit's power, cooling capacity, and other parameters to meet the requirements of different application scenarios.

[0039] Interface 2 can be a connector, which can be connected to pipe 3 by means of threaded connection, snap-fit ​​connection, flange connection, etc., to improve the efficiency and reliability of pipe 3 connection.

[0040] The number of interfaces 2 can be set according to the specific functions and application scenarios of the air conditioning unit. For example, for large air conditioning units, multiple interfaces 2 may be required to connect to different pipes 3, such as air inlet pipe, air outlet pipe, water inlet pipe, and water outlet pipe.

[0041] Interface 2 is located on the outer wall 11 of the pipe in the chassis 1. The specific location can be selected according to actual needs. For example, it can be located on the back, bottom, or side of the chassis 1 to facilitate the connection and layout of the pipe 3.

[0042] like Figure 5 As shown, any two interfaces 2 are staggered in a first direction so that at least two pipes 3 do not interfere with each other on the connecting wall 11. The first direction refers to the same outlet direction of at least two interfaces 2. It should be noted that the first direction can also be understood as the same extension direction of at least two pipes 3 within the area of ​​the connecting wall 11 of the casing 1. In this embodiment, the connection between the outdoor unit and the indoor unit is usually made in a predetermined direction, that is, the outlet direction of each interface 2 is the same within the area of ​​the connecting wall 11. In this embodiment, any two interfaces 2 being staggered in the first direction means that in the same outlet direction of multiple interfaces 2, the preceding interface 2 will not block the following interface 2, so that any two pipes 3 connected to the interface 2 will not interfere with each other. Thus, when connecting pipes 3, the obstruction of the preceding pipe 3 by the following pipe can be avoided. If multiple interfaces 2 on the outer wall of the casing 1 are arranged in a straight line in the extension direction of the pipes 3, when connecting pipes 3, the following pipe 3 may be blocked by the preceding pipe 3, requiring an increase in the height of the pipe 3 or the use of additional fittings to avoid this obstruction. In the air conditioning unit of this embodiment, any two interfaces 2 are staggered in the first direction, and the latter pipe 3 can be directly connected to the interface 2 without complicated avoidance operations, making installation convenient and saving installation costs.

[0043] Please continue reading. Figure 5 In some embodiments, adjacent interfaces 2 have a clearance distance in a second direction, wherein the second direction is perpendicular to the first direction, i.e., perpendicular to the extension direction of the pipe 3. The clearance distance ensures that adjacent pipes 3 do not interfere with each other when connected to interfaces 2. For example, if there is no clearance distance between adjacent interfaces 2, the adjacent pipes 3 may come into contact with each other when connected, affecting the normal use of the pipes 3.

[0044] Furthermore, in the second direction, the center distance L between two adjacent interfaces 2 satisfies: L≥D1+D2;

[0045] Where D1 and D2 represent the diameters of two adjacent interfaces 2, respectively.

[0046] In this embodiment, by limiting the center distance L between two adjacent interfaces 2, the clearance H between the two adjacent interfaces 2 can be defined, that is, H = L - (D1 + D2) / 2. The clearance H ensures that two adjacent pipes 3 will not contact each other when connected to the interface 2, and also provides sufficient space for the connection of the pipes 3. If the center distance between two adjacent interfaces 2 is less than D1 + D2, the clearance H will also decrease, thereby affecting the installation operation space, which is not conducive to the installation operation and affects the normal maintenance of the pipes 3.

[0047] Furthermore, in the second direction, the center distance between any two adjacent interfaces 2 can be equal or unequal, and can be adjusted according to actual needs to meet the connection requirements of different pipes 3. For example, when multiple interfaces 2 are of the same size, setting the center distance between two adjacent interfaces 2 to be equal can make the outer wall of the chassis 1 neater and more aesthetically pleasing, and also facilitate the layout and connection of pipes 3. When multiple interfaces 2 are of different sizes, the center distance between two adjacent interfaces 2 can be unequal. For larger interfaces 2, a larger center distance can be set to obtain a larger clearance and installation space, which facilitates the layout and connection of pipes 3.

[0048] In some implementations, in the second direction, at least two interfaces 2 are not on the same straight line.

[0049] Alternatively, in the second direction, at least two interfaces 2 are on the same straight line.

[0050] In this embodiment, the interfaces 2 can be arranged differently depending on the shape of the chassis 1. In the second direction, the multiple interfaces 2 can be either not on the same straight line or on the same straight line. For example, for a wide and low chassis 1, the multiple interfaces 2 can be not on the same straight line, which can make full use of the installation space on the outer wall of the chassis 1 and further increase the clearance between the interfaces 2, avoiding mutual interference between the pipes 3. For a narrow and long chassis 1, the multiple interfaces 2 can be on the same straight line, making the outer wall of the chassis 1 neater and more aesthetically pleasing, and also facilitating the layout and connection of the pipes 3.

[0051] The following is a specific embodiment in which interface 2 is provided in the pipe wall 11, combining the above-mentioned number of interfaces 2 and the center distance between interfaces 2:

[0052] like Figure 5 As shown, this embodiment has five interfaces 2, which are installed on the pipe wall 11. These interfaces 2 are used to connect different pipes 3 that are crucial to the operation of the air conditioning unit, such as the inlet and outlet water pipes for cooling circulation, the high-pressure inlet and low-pressure outlet air pipes for refrigerant circulation, and the drain pipes for discharging condensate.

[0053] The five interfaces 2 are staggered in their same outlet direction (first direction). For example, the high-pressure air inlet interface is located in the upper right area of ​​the connecting pipe wall 11, the low-pressure air outlet interface is below it and slightly to the left, the water inlet interface is to the right and slightly lower than the low-pressure air outlet interface, the water outlet interface is below the water inlet interface and further to the left, and the drain interface is located in the lower right area of ​​the connecting pipe wall 11. This staggered arrangement in the first direction ensures that each pipe 3 can extend along the connecting pipe wall 11 without interference after exiting from the interface 2. During actual installation of the pipes 3, workers can easily connect each pipe 3 to its corresponding interface 2 without worrying about mutual interference between the pipes 3, avoiding the need for additional adjustments to the pipe 3 routing or the use of adapter elbows due to pipe collisions, significantly improving installation efficiency and quality.

[0054] In the second direction, perpendicular to the first direction, there is a specific clearance between adjacent interfaces 2. The five interfaces 2 are not aligned on the same straight line in the second direction, but rather arranged in a staggered pattern. The center-to-center distance L between any two adjacent interfaces 2 satisfies L = D1 + D2. Since the diameter of each interface 2 is D1 = D2, this consistent center-to-center distance design ensures that adjacent pipes 3 will not contact or interfere with each other when connected to interfaces 2, providing sufficient space for the installation and maintenance of pipes 3. Simultaneously, the equal center-to-center distance between any two adjacent interfaces 2 in the second direction makes the overall layout of interfaces 2 more regular and orderly. While ensuring that the pipes 3 do not interfere with each other, it fully utilizes the space of the pipe wall 11 and also presents a neat and aesthetically pleasing effect.

[0055] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of interface 2 provided in this embodiment.

[0056] In some embodiments, interface 2 includes a mounting base 21 and a connecting post 22 connected to the mounting base 21. The mounting base is mounted on the chassis 1, and the connecting post 22 is used to connect the pipe 3. The mounting base 21 can be installed on the chassis 1 by welding, bolting, or other methods to ensure the stability and reliability of interface 2. The length and diameter of the connecting post 22 can be set according to actual needs to meet the connection requirements of different pipes 3.

[0057] Furthermore, the outer periphery of the connecting post 22 is provided with connecting threads 221. The connecting threads 221 make the connection between the pipe 3 and the interface 2 more secure and reliable, and also facilitate installation and disassembly.

[0058] In some embodiments, interface 2 further includes a valve 23, which is connected to the connecting post 22 and used to open or close interface 2. The valve 23 facilitates the control of the flow of pipe 3, making maintenance and repair of the air conditioning unit easier. The valve 23 can be a manual or electric valve, selected according to actual needs.

[0059] In some embodiments, the interface 2 also includes an identification section disposed on the mounting base 21 to distinguish interfaces 2 with different functions. The identification section can be configured in different shapes and protrude from the outer surface of the mounting base 21 for easy observation. The identification section can be a gas-shaped icon to indicate an interface 2 used for connecting a gas pipe, or a teardrop-shaped icon to indicate an interface 2 used for connecting a water pipe. In addition, the identification section can also use color coding, text coding, or other methods to help installation and maintenance personnel quickly identify interfaces 2 with different functions and avoid connection errors.
