Embodiment Construction

[0025] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. This embodiment provides a pipeline device designed according to the low flow resistance pipeline design method for uniform air supply, such as figure 1 , 2 As shown, it consists of a main pipe 1, several branch pipes 2 and several tees 3. The height of the main duct 1 decreases gradually along the airflow direction, and the shape of the tee 3 is designed according to the height of the main duct 1 along the airflow direction. During the process of designing this plumbing installation, the following four steps were followed:

[0026] Step 1: Determine the temperature T of the fluid at the inlet of the pipeline, the dynamic viscosity μ and density ρ of the fluid at this temperature, and determine the material of the pipeline; according to the total volume f...

Abstract

The invention discloses a uniform-air-supply low-flow-resistance pipeline device and a uniform-air-supply low-flow-resistance pipeline design method. The device comprises a main pipeline, tee joints and branch pipelines. The cross-section height of the main pipeline in the length direction is gradually reduced, so that the uniformity of the air supply amount of each branch pipeline is ensured; andthe surfaces of the connecting parts of inlets and outlets of the tee joints are curved surfaces, and the curved surfaces are circular arc surfaces for reducing flow resistance in the main pipeline.The air supply pipeline device can achieve uniform air supply and has the advantage of the low flow resistance.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning air supply control, and more specifically relates to a low-flow-resistance pipeline device for uniform air supply. Background technique [0002] With the development of society, industrial technology and human life have gradually increased the requirements for environmental protection and energy saving, and natural ventilation can no longer meet the requirements of modern industry and human life. The uneven air supply in the living area will lead to a decrease in people's comfort, and the uneven air supply in the industry will affect the production efficiency. [0003] For the air supply duct, the air supply volume depends on the static pressure of the air supply outlet. To ensure that the air supply volume of each air supply outlet is uniform, it is necessary to ensure that the static pressure of each air supply outlet is the same, that is, two adjacent The difference in dynamic pressur...
