Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline devices in the installation of air conditioning and ventilation equipment, and specifically relates to an air conditioning pipeline installation structure. Background Technology

[0002] Central air conditioning systems utilize multi-split systems, where one outdoor unit can connect to multiple indoor units. When multiple indoor units operate simultaneously, the overall energy efficiency ratio is very high, making it particularly suitable for medium to large apartments with multiple rooms. Indoor units come in various forms, including ceiling-mounted, ducted, wall-mounted, and floor-standing. Ceiling-mounted units, concealed within the ceiling, are the choice for most users who prioritize aesthetics and comfort.

[0003] Connecting the outdoor and indoor units of a central air conditioning system typically involves considering drain pipes, communication lines, and, most importantly, two copper pipes. These two copper pipes carry the refrigerant in the phase-change cycle, enabling the unit to cool or heat. The two copper pipes from the outdoor unit split into multiple branches at a branching point, which then connect to the individual indoor units. To ensure insulation, the copper pipes are wrapped with an insulation layer, resulting in a larger diameter. When these pipes pass through beams or walls, holes need to be drilled in the beams or walls, requiring a relatively large hole diameter. This layout needs to be designed and planned during the initial stages of renovation. Currently, due to manufacturing standards, the two copper pipes on the indoor unit are spaced vertically and extend outwards. After the indoor unit is suspended from the ceiling, the two copper pipes on the indoor unit continue to extend vertically for easy pipe connections. The two copper pipes from the outdoor unit also extend vertically, passing through the beams or walls of the building. This piping method results in vertically spaced holes in the beams or walls for the pipes. Taking the main beam as an example, the beam height is generally 30-40cm. The vertically spaced copper pipes for air conditioning have holes that occupy a large portion of the beam height, damaging the steel reinforcement inside the beam and affecting its structural strength. The lowest hole is far from the ceiling but close to the bottom of the beam, making it prone to breakage. This affects the beam's load-bearing capacity and seismic resistance, posing a certain risk to the structural stability of the entire house and building. In addition, it will also cause the ceiling to be lowered later, further compressing the space of some apartments with already low ceilings. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an air conditioning pipe installation structure that avoids the problem that the current air conditioning pipe openings are arranged vertically at intervals on the building, which affects the strength of the beam structure and may cause significant hidden dangers to the structural safety and stability of the building.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An air conditioning duct installation structure includes an indoor unit connected to the lower surface of the ceiling. A first copper pipe and a second copper pipe extend from the side of the indoor unit, with the first copper pipe located above the second copper pipe. A horizontal beam protrudes from the lower surface of the ceiling, and the indoor unit is located on one side of the beam. A first opening and a second opening are horizontally spaced through the beam. The first copper pipe extends horizontally and passes through the first opening. The second copper pipe is bent upwards to the height of the first copper pipe, then bent horizontally again and extends through the second opening.

[0006] To further improve the above technical solution, a first main pipe and a second main pipe that are parallel to each other are provided on the other side of the beam. The first main pipe and the second main pipe extend horizontally along the length of the beam below the ceiling. The first main pipe and the second main pipe are at the same height and their heights correspond to the height of the first copper pipe. The free end of the first copper tube, after passing through the first opening, is bent horizontally and parallel to the first main tube, and is connected to the first main tube through the first branch. The free end of the second copper pipe, which passes through the second opening, is connected to an inverted U-shaped section. The U-shaped section passes through the gap between the first and second main pipes and the ceiling. The end of the U-shaped section is bent horizontally and parallel to the second main pipe. It is connected to the second main pipe through the second branch.

[0007] Furthermore, the ends of the first and second main pipes pass through horizontally spaced through openings in the corresponding walls or beams.

[0008] Furthermore, the distance from the upper edge of the first and second openings to the lower surface of the ceiling corresponds to the diameter of the second copper tube.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This utility model's air conditioning pipe installation structure features horizontally spaced openings in the beam for copper pipes to pass through. Although there may be a certain height difference in the copper pipes on the equipment, through a certain number of bends, the copper pipes pass through the horizontally spaced openings one-to-one. The horizontally spaced openings reduce the vertical impact on the beam's height. Combined with the reinforcement arrangement specifications of the beam's reinforced concrete structure, this reduces damage to the beam's internal reinforcement, minimizing the impact on the beam's structural strength. Furthermore, the greater distance from the lower edge of the beam minimizes the impact on the main tensile reinforcement at the lower edge. This solves the problem of excessive damage to the beam, protecting the stability and safety of the building structure. Subsequent ceiling installation can also be raised accordingly, saving floor height and maximizing space. Attached Figure Description

[0013] Please see Figure 1 , Figure 3The air conditioning pipe installation structure of a specific embodiment includes an indoor unit 1, which is connected to the lower surface of a ceiling 2. A first copper pipe 11 and a second copper pipe 12 are connected to the side of the indoor unit 1. The first copper pipe 11 is located above the second copper pipe 12. A horizontal beam 3 protrudes from the lower surface of the ceiling 2. The indoor unit 1 is located on one side of the beam 3. A first opening 31 and a second opening 32 with horizontal spacing are opened through the beam 3. The height corresponds to the height of the first copper pipe 11. The first copper pipe 11 extends horizontally and passes through the first opening 31. The second copper pipe 12 is bent upward to the height of the first copper pipe 11, and then bent horizontally and extends through the second opening 32. Understandably, the horizontal extension of the copper tube can be in a straight line or in a horizontal inward change of direction. In this embodiment, the first copper tube 11 extends horizontally and changes direction by 90° before passing through the first opening 31. Similarly, the second copper tube 12 can also extend or change direction horizontally before bending upward, so as to obtain the space required for bending upward and not interfere with the first copper tube 11.

[0014] In the air conditioning duct installation structure of this embodiment, horizontally spaced openings are made in beam 3 for copper pipes to pass through. Although there may be a certain height difference in the copper pipes on the equipment, through a certain number of bends, the copper pipes pass through the horizontally spaced openings on beam 3 one-to-one. The horizontally spaced openings reduce the vertical occupation and damage to the height dimension of beam 3. Combined with the internal reinforcement arrangement specifications of the beam's reinforced concrete structure, this reduces damage to the internal reinforcement of the beam and minimizes the impact on the structural strength of beam 3. The distance from the lower edge of beam 3 is also greater, resulting in minimal impact on the main tensile reinforcement of the lower edge of beam 3. This solves the problem of excessive damage to the beam and protects the stability and safety of the building structure. Because a horizontal pipe laying method is adopted, more areas with pipe routing are vertically elevated, and subsequent ceiling installations can be correspondingly raised, saving floor height and enlarging the space size.

[0015] Please continue reading Figure 1 and Figure 2On the other side of beam 3, there are parallel first main pipe 51 and second main pipe 52. The first main pipe 51 and second main pipe 52 extend horizontally along the length of beam 3 below ceiling 2. The first main pipe 51 and second main pipe 52 are at the same height, corresponding to the height of the first copper pipe 11. The free end of the first copper pipe 11 passes through the first opening 31, bends horizontally, and is parallel to the first main pipe 51, and is connected to the first main pipe 51 through the first branch 61. The free end of the second copper pipe 12 passes through the second opening 32 and is connected to an inverted U-shaped segment 121. The U-shaped segment 121 passes through the gap between the first main pipe 51 and second main pipe 52 and ceiling 2. The end of the U-shaped segment 121 is bent horizontally and is parallel to the second main pipe 52, and is connected to the second main pipe 52 through the second branch 62. The first main pipe 51 and second main pipe 52 are also horizontally spaced apart to facilitate adaptation and connection with the horizontal first copper pipe 11 and second copper pipe 12. The diameter of the U-shaped section 121 corresponds to the diameter of the second copper pipe 12. The first branch 61 and the second branch 62 are both horizontally positioned and interconnected. Understandably, after a certain extension length, each pipe can be fixed to the ceiling 2 via pipe clamps to improve pipeline stability. The pipe clamps and branch joints are existing components, and their specific structures will not be described in detail here. The inverted U-shaped section 121 can be a separate connecting section; in practice, it is more often an integrated form consisting of the second copper pipe 12 bent upwards, then horizontally, extending across the first and second main pipes, and then bending downwards. To avoid damage to the copper pipes, the "bends" mentioned in this text are not specified as 90° bends; they can be more inclined extensions. All openings should be of appropriate size, slightly larger than the diameter of the pipes they pass through.

[0016] The ends of the first main pipe 51 and the second main pipe 52 pass through horizontally spaced through openings 8 on the corresponding walls or beams. Here, the same design principle and effect as described above are used, and the first main pipe 51 and the second main pipe 52 also use horizontally spaced openings when passing through the load-bearing walls or beams. The specific effect is the same as described above and will not be repeated here.

[0017] The distance from the upper edge of the first opening 31 and the second opening 32 to the lower surface of the ceiling 2 corresponds to the diameter of the second copper pipe 12. This facilitates the passage of the U-shaped section 121 of the second copper pipe 12 through the gap between the top of the first main pipe 51 and the second main pipe 52 and the ceiling 2. In practice, this also ensures that the openings are located at the upper part of the beam 3. Taking construction as an example, the openings can be about 2 cm above the ceiling at the top of the beam (even if there is insufficient space when the pipe passes above, it can overlap by appropriately allowing the pipe below to bend or bend). Two to three openings are needed laterally, leaving at least 10-20 cm of unobstructed space below the beam, thus better ensuring structural strength.

[0018] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
