In people's daily life, every kitchen needs to use the kitchen smoke hood to ensure the fresh air in the kitchen, so the kitchen smoke hood is a form of local smoke exhaust. The hood must be designed to stabilize the wind speed. The total air volume of the kitchen hood can be obtained by calculating the wind speed of the hood. Through the calculation of total air volume, the cross-sectional area of kitchen smoke exhaust pipe is determined. Then according to the overall height of the kitchen to determine the height of the pipeline.

廚房排煙罩選用風機時應準確計算風管的風速、流量、風阻，這樣在選擇風機過程中能準確的確定風機的風量、風壓、電機功率。從而達到的良好效果，對日常經營中減低成本起到重中之重的作用。濟南排煙罩

When selecting the fan for the kitchen exhaust hood, the wind speed, flow rate and wind resistance of the air duct should be accurately calculated, so that the air volume, air pressure and motor power of the fan can be accurately determined in the process of selecting the fan. So as to achieve the good effect of energy saving, and play a key role in reducing costs in daily operation.
