Problems solved by technology
[0003] (1) Due to the different opening branches and opening positions of the static pressure distribution box, there are many specifications of the static pressure distribution box, which is not conducive to prefabrication and on-site installation;
[0004] (2) Due to the limited vertical distance between the hoisting height of the air-conditioning equipment and the suspended ceiling, the general branch pipe cannot be connected with a 90° elbow from the bottom of the static pressure distribution box;
[0005] (3) Since the static pressure distribution box is connected to the vicinity of the tuyere through the rectangular air duct, the horizontal galvanized round pipe and the heat preservation hose in turn, the said tuyere is installed on the said air supply static pressure box, and the said horizontal galvanized round pipe includes Elbows and straight pipes are sometimes bent arbitrarily in order to follow the airflow, resulting in a huge workload for on-site measurement, which is not conducive to prefabrication, thereby increasing material and labor costs, and increasing the airflow resistance in the downstream branch pipe;
[0006] (4) Due to the time-consuming and labor-intensive installation of the horizontal galvanized round pipe, it is easy to lead to improper installation and forced borrowing of the insulation hose or the excessive length of the hose, which increases the air supply resistance at the end

Abstract
The invention discloses a downstream air supply line for a variable air volume terminal and a mounting method of the downstream air supply line and aims to solve the problems the prior art such that mounting of the downstream air supply line at the variable air volume terminal needs high consumption of labor and short construction progress and the vertical height from the variable air volume terminal to a suspended ceiling is limited. The downstream air supply line comprises a static distribution box, connecting pipes, customized bends and a plurality of spiral straight pipes connected to the variable air volume terminal; the cross section of each of the connecting pipes, the customized bends and the spiral straight pipes is round and customized; the static distribution box is provided with a plurality of holes; every two adjacent spiral straight pipes are hermetically connected through the connecting pipes or the customized bends; the spiral straight pipes close to the static distribution pipe are hermetically connected to the holes of the static distribution box through the connecting pipes or the customized bends; the connecting pipes and / or the customized bends are in socket-spigot connection with the static distribution box or the spiral straight pipes, respectively. The downstream air supply line has the advantages that construction is facilitated, quality is guaranteed, construction period is shortened, and material and manpower costs are lowered.
Description
technical field [0001] The invention relates to an air supply pipeline and an installation method thereof. Background technique [0002] At present, the installation form of the downstream air supply pipe of the variable air volume terminal device is generally a rectangular air duct, a static pressure distribution box, a horizontal galvanized round pipe, a thermal insulation hose not exceeding 2m, and an air supply static pressure box. In the previous installation process of the above forms, the following construction problems were often encountered: [0003] (1) Due to the different opening branches and opening positions of the static pressure distribution box, there are many specifications of the static pressure distribution box, which is not conducive to prefabrication and on-site installation; [0004] (2) Due to the limited vertical distance between the hoisting height of the air-conditioning equipment and the suspended ceiling, the general branch pipe cannot be connec...
