Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1:

[0027] Based on the technical defect in the prior art that the building structure is easily damaged due to the too large pipe diameter of the pipeline, please refer to Figures 1-7 , a new all-air air-conditioning distribution pipeline system provided by the present invention can achieve the purpose of reducing the pipe diameter by using the connection between the square-to-round direct joint 4, the circular straight pipe 5 and the round-to-square elbow 6, reduce the damage to the main building structure during system construction, avoid construction accidents, and ensure that the air volume passing through the pipeline can carry sufficient cooling and heating capacity and fresh air demand. Among them, the reducing-diameter pipe joint 1 is connected to the air outlet of the unit as a flexible connection. One end of the reducing-diameter pipe joint 1 is connected with the first rectangular straight pipe 2. The first rectangular straight pipe 2, the second rectangular straight pipe 7 and the third rectangular straight pipe 9 are the main pipelines of the entire distribution system, and are responsible for transporting the cooling and heating capacity and fresh air of the system. One end of the first rectangular straight pipe 2 is connected with a transition assembly for passing through the wall or the beam. The transition assembly is connected to one end of the second rectangular straight pipe 7. The other end of the second rectangular straight pipe 7 is connected to one end of the third rectangular straight pipe 9 through a rectangular direct joint 8. There is a blocking node in the middle position inside the rectangular direct joint 8, which can ensure a certain insertion depth of the rectangular straight pipe and ensure the coordination and tightness on both sides. The other end of the third rectangular straight pipe 9 is connected with a rectangular elbow 10; the rectangular elbow 10 is used for the direction conversion of the pipeline and changes the connection direction of the third rectangular straight pipe 9.

[0028] To solve the problems of the distribution pipeline passing through the lintel and the wall, a transition component is provided. The transition component includes a square-to-round direct connector 4 connected to the rectangular straight pipe 2. The square-to-round direct connector 4 is connected to the round-to-square elbow 6 through two round straight pipes 5. The round-to-square elbow 6 is connected to one end of the rectangular straight pipe 7. The square-to-round direct connector 4 is used to connect the round straight pipe 5 and the rectangular straight pipe 2, mainly for passing through the lintel and the wall, and can realize the conversion of the perfect connection between the round pipe and the square pipe, and well solve the problem of the pipeline passing through the lintel and the wall. The round straight pipe 5 is mainly used for passing through the wall or the lintel. By reducing the pipe diameter, the damage to the main structure of the building caused by system construction can be reduced. The round-to-square elbow 6 is used for direct turning after passing through the lintel or the wall, and can minimize the space for direction change, and can also be used for connection before passing through the lintel or the wall in a narrow area where the square-to-round direct connector 4 cannot be placed.

[0029] To facilitate the conversion of the perfect connection between the round pipe and the square pipe, a rectangular hole 41 and two round holes 42 for connecting the rectangular straight pipe 2 and the round straight pipe 5 are provided at both ends of the square-to-round direct connector 4. In this way, the rectangular straight pipe 2 can be inserted into the rectangular hole 41 to form a connection, and the round straight pipe 5 can be inserted into the round hole 42 to form a connection.

[0030] To facilitate the turning of the round straight pipe 5 after passing through the lintel or the wall, a round hole 61 and a rectangular hole 62 for connecting the round straight pipe 5 and the rectangular straight pipe 7 are provided at both ends of the round-to-square elbow 6. In this way, the round straight pipe 5 can be inserted into the round hole 61 to form a connection, and the rectangular straight pipe 7 can be inserted into the rectangular hole 62 to form a connection.

[0031] To facilitate the connection between the rectangular straight pipe 7 and the rectangular straight pipe 9, a rectangular hole 81 and a rectangular hole 101 are provided at both ends of the rectangular direct connector 8 and the rectangular elbow 10 respectively. In this way, the rectangular straight pipe 7 and the rectangular straight pipe 9 can be inserted into the rectangular hole 81 and the rectangular hole 101 respectively to form a connection.

[0032] To avoid the loss of cold and heat transported by the all-air system, sealing rings 11 are provided in the rectangular hole 41, the round hole 42, the round hole 61, the rectangular hole 62, the rectangular hole 81 and the rectangular hole 101, which can improve the sealing performance of each connection part and reduce leakage.

[0033] It should also be noted based on this embodiment that most of the metal pipes used in the current construction of all-air systems are fabricated on-site from galvanized steel sheets. The processing process is time-consuming, affecting the construction period. In addition, it is necessary to attach a rubber-plastic or polyurethane insulation layer for heat insulation, resulting in an increase in construction costs. Most of the non-metal pipes used are hoses, with great construction difficulty. During installation, they are prone to bending and blockage, resulting in the failure to meet the design requirements during later operation. Moreover, when transporting cold energy, additional rubber-plastic insulation is still required, and the construction process is complex. This transfer and distribution pipeline system uses all EPP pipes, which can well solve the above problems. There is no need to process pipes on-site, no need for additional insulation, and mechanical connection between pipes can be directly carried out. Moreover, it is light in weight, fire-resistant and flame-retardant, and has high compressive resistance.

[0034] Embodiment Two:

[0035] During the installation of the entire pipeline system, it is necessary to use the hanging clamp assembly 3 to support and fix it at the roof to ensure the stability of the entire pipeline system. Please refer to Figure 1 and Figure 3 , on the basis of Embodiment One, the rectangular straight pipe one 2, the rectangular straight pipe two 7, and the rectangular straight pipe three 9 are all installed on the hanging clamp assembly 3, and the hanging clamp assembly 3 is fixed at the roof; the hanging clamp assembly 3 can fix the rectangular straight pipe one 2, the rectangular straight pipe two 7, and the rectangular straight pipe three 9, so as to achieve the effect of stable installation.

[0036] To facilitate the fixation of the rectangular straight pipe one 2, the rectangular straight pipe two 7, and the rectangular straight pipe three 9, the hanging clamp assembly 3 is provided. The hanging clamp assembly 3 includes two suspension rods 31 fixed at the roof. The bottom of the suspension rod 31 is installed with a fixing frame 32 through a nut 33. Both ends of the fixing frame 32 are provided with clamping openings, and a hanging buckle 34 is installed inside the clamping openings through bolts. The hanging buckle 34 is clamped on the outer sides of the rectangular straight pipe one 2, the rectangular straight pipe two 7, and the rectangular straight pipe three 9. After fixing the suspension rod 31 on the roof, then install the fixing frame 32 at the bottom of the suspension rod 31, and finally insert the hanging buckle 34 at the bottom of the rectangular straight pipe and use bolts to fix the hanging buckle 34 on the fixing frame 32.

[0037] It can be seen from the above embodiments that the usage process of this device is as follows: The cold / heat energy and fresh air output by the unit pass through the reducer pipe joint 1 into the rectangular straight pipe one 2. Among them, the hanging clamp assembly 3 plays a role in fixing and positioning the entire all-air pipeline transfer system. If there is a situation of passing through a lintel or a wall, it will pass through the square-to-round direct joint 4 and then reach the circular straight pipe 5 for passing through the wall or the lintel, and then be connected and redirected by the round-to-square elbow 6, and continue to be transported through the rectangular straight pipe two 7, and then be redirected by the rectangular elbow 10, and the cold / heat energy and fresh air transported by the unit are transported to the designated position.

The scope of the present utility model is defined by the appended claims and their equivalents.
