1. double hundred as general air outlet can also be used directly supporting the fan coil air vents Wuhan, central air conditioning system is widely used in the end, can also with multi-leaf off valve to adjust the amount of wind. 2. single Grille adjustable up and down direction, return air filter in combination with air, segments angle can be adjusted between blade with ABS plastic mounting bracket. Fixed filter removed during cleaning can slide over the Wuhan abs air filter, cleaned and then continue to use the push from the chute. 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 outlet, select the appropriate outlet types. 2) the amount of wind needed [supply or discharge (back) wind] Wuhan, central air conditioning vent in the outlet of the neck (or outlet section of the Import and Export Department) within the allowable wind speed range, to determine the required size of the outlet. Such as by air speed (usually 2 ~ 5m / s) when determining the size of the 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. Wuhan air conditioning vent, Wuhan Han Wei Li Yuen (certified), the outlet provided by Wuhan Han Wei Liyuan heating equipment Limited. Wuhan Han Wei Li Yuen-being of Equipment Co., Ltd. (www.whhwly.com) is a leader in Wuhan, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs.
