The method of calculation of fire smoke exhaust fan with the continuous improvement of living standards, people on the air quality requirements are increasing. We all know that inevitably produce fumes when cooking. Wherein the exhaust fan and air purifier applications to be very good for us to solve this problem. And the kitchen hood fan design is reasonable subsequent installation of smoke purification equipment preconditions. So according to the area, or how to choose the amount of smoke exhaust fan do? Our technical staff as we summed up the points. 1, when we use the exhaust fan in the atrium volume of less than 17,000 cubic meters, which is the amount of smoke six times its volume / hour ventilation calculation; 2, when we use the exhaust fan in the atrium volume greater than 17,000 cubic meters when the amount of smoke it four times its volume / hour ventilation calculation, exhaust fan, but need to be aware of is the minimum amount of smoke not less than 102,000 cubic meters / hour. To fully understand the fire exhaust fan effective specific location in order to calculate the amount of wind almost every residential building now has a shadow fire exhaust fan, exhaust fan price, it is due to the presence of exhaust fan fire, make people more at ease, not all day beware of the fire appears, exhaust fan sales, for the amount of wind and fire exhaust fan blower air volume should be how to calculate it? This is a lot of construction workers want to know one thing, the exhaust fan fire this problem, and now small series for your detailed analysis, allowing you to more clearly understand some of the knowledge of the fire exhaust fan. First, for the amount of wind and fire exhaust fan blower amount of wind that we should install exhaust fan fire place in the room and also you need to know the exact location of its exclusive air to calculate the exhaust fan fire smoke or take on a smoke partition When more than 6.00m headroom is not zoned smoke partition room, per square meter area shall be not less than 60m ^ 3 / h Computing (single wind turbine exhaust amount not less than the minimum 7200ms / h), air supply by 50% of the amount of exhaust, manufacturing exhaust fan, it is not if I'm a smoke partition is 1000M2, the amount of smoke that is 1000 * 60 = 60000M3 / H, the air supply is 30000M3 / H.
