1. diffuser outlet type chosen main control parameters. Materials, specifications, outlet velocity, total pressure loss and airflow range and so on. 2. diffuser materials are mainly plastic, steel and aluminum types. 3. Selection of points 1) According to the engineering characteristics of the airflow required tissue types. Air conditioning performance and methods, select the appropriate outlet types. 2) the amount of wind needed [supply or discharge (back) wind], in the outlet of the neck (or outlet section of the Import and Export) allowable wind speed range Wuhan abs outlet, the outlet to determine the required size. Such as by air speed (usually 2 ~ 5m / s) when determining the size of Wuhan, central air conditioning outlet, the outlet should be considered effective area ratio (typically 30% to 60%). The main technical performance outlet 3) verification of the selection. Such as range, pressure loss, noise level and wind speed and temperature difference in the work area. 4) to determine the layout of the selected outlet installation and connection with the duct.
