A clean room with a compact design must be used because its height is limited by the height of civil engineering. Aluminum alloy air supply outlet characteristics of some local purification equipment The aluminum alloy air supply outlet has an adherent (horizontal) airflow, and its structure is a multi-layer cone. As the indoor-induced air flow is greater than the exhaust air volume, the blowing air flow decelerates rapidly. Therefore, relatively large air volume can be supplied for any size area and the size of the diffusion radius changes within the given air volume range.
The HVAC diffusers shall be customized according to the opening size. In order to facilitate installation, the actual inner diameter (length and width) of the HVAC diffusers will be slightly less than the net opening size by 0.5-1.0 cm. Louver HVAC diffusers are widely used as air supply outlets in air conditioning systems. According to the use requirements, aluminum air volume regulating valves (miter gates) can be equipped behind the HVAC diffusers.
The supply air diffuser has the function to take air from the outside environment and let it pass through it,then enter the indoor atmosphere. This process not only helps in enhancing HVAC performance but reduces energy wastage as well. With a damper, the air diffuser can control the volume of air flowing into a room or area you have chosen and helps in controlling the direction of airflow. When air coming directly from the air ducts sometimes causes noise. The air diffuser also can reduce noise as air comes out of the vents in a minimum amount in different directions which makes the noise process less. See more details at https://www.chinaventech.com/.
