Fan options: air volume calculation method to select the desired fan according to arrangement of kitchen space and fume hood are as follows: 1, the overall exhaust volume, according to the kitchen space, air changes per hour 40-60 times. Such as kitchen total area of ??160 square meters, a height of 3 meters. We need ventilation to 160X3X60 = 28800m3 / h. 2, local kitchen exhaust hood according to the windward side (minus the perimeter wall of the fume hood length), the wind speed of about 0.5 meters per second. Such as kitchen exhaust hood perimeter of 25 meters, where the wall length of 10 meters. The amount of ventilation required to 3600X (25-10) X0.5 = 27000m3 / h II: Calculation of the required static pressure fan duct according to the situation: 1, based on the amount of wind and wind speed (wind speed 10-15 m / s or so) to determine duct cross-sectional area. Duct aspect ratio should not exceed 2: 1 (to save material and reduce the drag). 2, according to the wind speed, the wind pipe cross-sectional area, elbows, reducers, etc. to calculate the drag (ie the required fan static pressure). Three: calculated based on air flow, static pressure. Select the appropriate fan. Without power fan is to promote the use of nature's natural wind speed rotation of the turbine fan principle and indoor and outdoor air convection, the air flow in any direction parallel wucheng roof exhaust fan manufacturers, accelerate and into vertical air flow from the bottom up, to improve indoor ventilation effect of a device. The fan no electricity, no impatient tone Panjin roof exhaust fan manufacturers, long-term operation. According to the laws of nature and its air airflow principle Fushun roof exhaust fan manufacturers, is set at the top of the roof of rationalization can quickly exhaust gas chamber hot and dirty, improve the indoor environment.
