The location of the kitchen must be more than 20 meters away from the residential area. When the height of the building where the kitchen is located is less than 15 meters, the air outlet must be placed on the top of the building. If the height of the building where the kitchen is located is more than 15 meters and the kitchen is more than 15 meters, the height of the smoke exhaust outlet should be higher than the location of the kitchen.

集氣罩距離地面高度不小于1.9米不大于2.3米，距離地面過低廚師會碰頭，過高不利于集氣罩收集油煙，集氣罩的長度和寬度都應該超過設備100mm，也就是說集氣罩要完全能覆蓋設備。

The height of the gas collection hood from the ground should not be less than 1.9 meters and not more than 2.3 meters. If it is too low from the ground, the chef may encounter it. If it is too high, it is not conducive to the collection hood collecting oil fumes. The length and width of the gas collection hood should exceed 100mm of the equipment, which means that the gas collection hood should fully cover the equipment.

設計排風管道的走向時要避開消防管道空調管道，一旦與其沖突，后期安裝會很麻煩。設盡量減少風管彎頭和變徑，出現彎頭時角度在90度以內，直線管道的排風效果是佳的。

When designing the direction of the exhaust duct, it is important to avoid fire and air conditioning ducts. Once in conflict with them, installation in the later stages can be very troublesome. When designing, minimize the number of air duct bends and diameter changes as much as possible. When elbows occur, the angle should be within 90 degrees, and the exhaust effect of straight pipes is the best.

油煙凈化器的風量一般要比排煙風機稍大一些。至于對應油煙凈化器和排煙風機風量選擇可對應生產廠家的參數表，正規合格的生產廠家參照表大同小異。

The air volume of the oil fume purifier is generally slightly larger than that of the smoke exhaust fan. As for the selection of corresponding oil fume purifier and smoke exhaust fan air volume, it can correspond to the parameter table of the manufacturer, and the formal and qualified manufacturers can refer to the table with similar differences.

風機與風管連接時，在風機進風口和出風口兩倍葉輪直徑長度范圍內都不能有彎頭，如果出現彎頭，進風口可能會造成風機性能異常，出風口可能會引起管道阻力增加，導致風機發風量下降。

When connecting the fan to the air duct, there should be no bends within the length range of twice the impeller diameter of the fan inlet and outlet. If there are bends, the inlet may cause abnormal performance of the fan, and the outlet may cause an increase in pipeline resistance, leading to a decrease in fan air output.
