Working Principle Of Aluminum Alloy Shutters

- Sep 01, 2020-

Aluminum alloy shutters are used for supply and return air in the ventilation and air conditioning system. They can be installed directly on the end of the pipe or on the ceiling or on the wall or door. With the rapid development of science and technology and industrial economy in recent years, aluminum The increasing demand for alloy tuyere welding structural parts has made the weldability research of aluminum alloy tuyere also in-depth.


The swirling tuyere in the aluminum alloy tuyere uses the rotation of the outlet wind to send the air out in a spiral shape, resulting in a relatively high induction ratio, so that the supply air and the surrounding indoor air are rapidly mixed, which is different from the traditional diffuser. The air outlet grooves of the tuyere are arranged radially, and the air supply in the air duct is guided by the air outlet groove of the swirling air outlet to form a jet in the tangential direction. The air supply of the entire aluminum alloy tuyere is caused by multiple jets. A typhoon-like vortex. The central area of the vortex forms a negative pressure zone, which induces the surrounding indoor air to quickly mix with the supply air, and the entire supply air flow is in a stable horizontal diffusion flow state. Its induction ratio is 10 of that of a conventional diffuser. -20 times.


1. The single-layer movable louver tuyere is often used for the return vent and also for the supply vent.


2. When used in the return air port, it can be equipped with FG type air port filter; when used in the air supply port, it can be equipped with JT type air port regulating valve.


3. The movable louver can be adjusted in the range of 0~180°, adjusting the combination of different blade angles can get different diffusion angle and air supply distance.


4. The tuyere frame is divided into wide and narrow, and the size can be customized.
