来源:/添加时间:2018-03-07 14:29:18
  通风位置尽可能高,最好是吸顶安装,风道同样是越短越好,减少管道阻尼噪音。
  The position of ventilation is as high as possible, it is better to absorb the top of the installation, the better the air duct is as short as possible, reducing the noise of the pipe damping.
  厨房的排烟和通风设计原则是:抽油烟机的管道尽可能短,长度不得超过1.5米,抽油烟机设计国家标准是1.5米排烟长度为条件,测定噪音和空气排量数据的。烟管长度超过1.5米后噪音超标、排烟能力下降。
  The design principles of smoke exhaust and ventilation in kitchen are as follows: the pipeline of the hood is as short as possible, and the length should not exceed 1.5 meters. The design standard of hood is 1.5 meters and the length of exhaust gas is the condition, and the data of noise and air displacement are measured. After the pipe length is over 1.5 meters, the noise exceeds the standard and the capacity of exhaust fume drops.
  烟道只能装一个弯头,就是抽油烟机出口由垂直烟道变为水平烟道。加一个直角弯头等于加长1米烟道。
  The flue can only be equipped with one elbow, that is, the exit of the smoker is transformed from a vertical flue to a horizontal flue. A right angle elbow is equal to 1 meters long.
  送风系统应为直流方式,厨房的通风系统宜采用变速风机或关联风机进行送排风
  The air supply system should be DC, and the ventilation system of the kitchen should be carried out by the variable speed fan or the associated fan.
  机房、风机及风管的布置,厨房的排风机宜设在厨房的上部,厨房为公共建筑中的一部分时,其排风机宜设在屋顶层,这可以使风道内处于负压状态,避免气味外溢。厨房的排风机一般应选用离心风机,厨房的排风管应尽量避免过长的水平风道。厨房的排风竖井最好与排烟道靠在一起以加大抽力。

  Room, fan and air pipe layout, the kitchen exhaust machine should be located in the kitchen of the upper part of the kitchen as part of a public building when the exhaust machine should be located on the roof layer, which can make the state of negative pressure in the air duct to avoid odor overflow. A centrifugal fan should be used in the kitchen exhausting machine, and the exhaust duct of the kitchen should be avoided as long as possible. The draught shaft in the kitchen is better to be leaned with the exhaust duct to increase the pumping force.
  防火、排烟,厨房的排气系统宜按防火分区划分,尽量不穿过防火墙,穿过时应装防火阀。厨房通风系统的管道应采用不燃烧材料制成。
  Fire prevention, exhaust smoke, the kitchen exhaust system should be divided according to the fire zone, try not to pass through the firewall, when through the fire valve should be installed. The pipe of the kitchen ventilation system should be made of non - burning material.
  送排风口布置,厨房内送、排风口的布置应按灶具的具体位置加以考虑,不要让送风射流扰乱灶具的排风性通。确定送风出口的出口风速时,在距地2m左右时的区域风速<0.25m/s较为理想。送风口应沿排风罩方向布置,离开罩子前方最小0.7m,而排风口距排风罩越远越好。
  The layout of the exhaust tuyere, the layout of the air vent in the kitchen should be considered according to the specific position of the kitchen utensils, and do not let the air flow jet disturb the exhaust ventilation of the kitchen stove. When the wind speed of the outlet is determined, the regional wind speed of <0.25m/s at about 2m is more ideal. The outlet should be arranged in the direction along the hood, leaving the front cover and the minimum 0.7m, the air outlet hood from far away.
