Problems solved by technology

The problems of the uniform air supply duct include: 1) the static plenum takes up a lot of space, which will increase the volume of the air duct, which is not conducive to the layout; 2) the air flows from the static plenum into the dynamic plenum through the narrow air outlet, and the flow resistance is large. Easy to generate noise; 3) The structure of the air duct is relatively complex and difficult to process

Abstract

The invention discloses a uniform air delivery duct for a square cabin based on adjustable deflectors. The uniform air delivery duct comprises an air duct body (1) with a uniform section, an air inlet(2) is formed in one end of the air duct body (1), and the other end of the air duct body (1) is closed; a plurality of air outlets (3) are sequentially formed in the air duct body (1) in the air flow direction, the angle-adjustable deflectors (6, 7 and 8) are arranged on the portions, between the adjacent air outlets (3), in the air duct body (1) respectively, and the total heights of the deflectors are progressively increased in sequence in the air flow direction. The uniform air delivery duct for the square cabin based on the adjustable deflectors is high in air outlet uniformity, low in aerodynamic noise and easy to process and install.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment for shelters, in particular to a uniform air supply channel for shelters based on adjustable deflectors, which has good air outlet uniformity, low aerodynamic noise, and is easy to process and install. Background technique [0002] Air ducts are usually arranged on both sides of the roof of the shelter, and the air is supplied by the air conditioner installed at the front or rear of the cabin to regulate the temperature inside the cabin. Due to the limitation of installation space, the general air duct needs to be made into a curved air duct, which closely fits the wall of the connection between the large plates on both sides of the shelter. The air conditioners used in shelters generally have a large air volume. When working in cooling or heating modes, the air flow is fast and can fill the air duct instantly, so the air output is uniform. However, when the high-speed air flow ...
