Selection of filter air outlet

Selection of filter air outlet
 
What aspects should be considered in the selection of filter air outlets?
There are many types of air outlets, the selection should pay attention to the following principles:
1. Understand the type, function, scope of application and structure type of the air outlet.
2. According to the required air volume and within the allowable wind speed range of the neck of the air outlet, determine the type of air outlet required.
3. Check the main technical performance of the selected air outlet.
4. Determine the layout and installation method of the selected air outlet and the connection method with the air duct.
 
Second, understand the selection points:
1. The layout of high-efficiency air supply outlets needs to comprehensively consider the requirements of indoor airflow organization, noise, building decoration, installation and maintenance, etc.
2. Select high-efficiency air outlets according to the room structure. If there is a suspended ceiling, round and square diffusers should be used respectively according to the height of the air-conditioning area and the air flow requirements of the place of use.
3. For the installation of side-mounted replacement air outlet, the height from the ground should be less than 0.8m; the outlet wind speed should not be greater than 0.2m/s for civil buildings and 0.5m/s for industrial buildings.
4. For places with large indoor heat dissipation or tall spaces, the lower air outlet with stable airflow should be preferred.
5. The outlet wind speed of the high-efficiency air outlet should be determined according to factors such as air supply mode, air supply type, installation height, indoor allowable wind speed and noise.
