The obstacles to installing smoke curtain in Jinan kitchen have been cleared, and the ground has no obstruction to the construction of debris. It has the characteristics of light weight, high strength, no combustion, sound insulation, heat insulation, moisture proof, water resistance, long service life and so on. It is a new generation of energy-saving and environmental protection green products. Magnesium glass composite duct is mainly used in building, decoration, fire protection and other fields, especially in restaurants, hotels, shopping malls and other crowded places, as well as basement, civil air defense, mines and other humid environmental engineering.

　　廚房排氣應避免大量空調空間中的空氣被抽走。應避免使用自然通風和機械通風。自然通風和機械通風都應考慮新鮮空氣的路徑，避免死氣沉沉的區域，以便於抽排室內汙染空氣。機械送風應通過風管和送風口進行。成人漫画下载链接係統不應複雜，應避免局部風速。新風補充量應占排風量的70%-80%。

　　Kitchen exhaust should avoid a large amount of air in the air-conditioned space being pumped away. Natural ventilation and mechanical ventilation should be avoided. Natural ventilation and mechanical ventilation should consider the path of fresh air to avoid dead areas, so as to facilitate the extraction of indoor polluted air. Mechanical air supply shall be carried out through air ducts and air outlets. Pipeline system should not be complicated and local wind speed should be avoided. Fresh air supply should account for 70-80% of the exhaust air.

　　由於廚房的結構和廚房在建築中的位置不同，有條件的廚房應由建築的空調係統有序地提供。但今天遇到的大多數情況是沒有廚房空氣供應係統的建築。很多有餐廳、廚房等的建築，隻設計了集中供暖係統，沒有集中空調係統。當廚房處於工作狀態時，排氣係統投入運行，廚房處於負壓狀態。新鮮空氣的來源包括室外新鮮空氣的滲透和從餐廳到廚房的大量空氣。

　　Because the structure of the kitchen is different from the position of the kitchen in the building, the conditional kitchen should be provided orderly by the central air conditioning system of the building. But most of today's situations are buildings without kitchen air supply systems. Many buildings with restaurants, kitchens and so on have only designed central heating system, but no central air conditioning system. When the kitchen is in working state, the exhaust system is put into operation, and the kitchen is in negative pressure state. The sources of fresh air include the infiltration of outdoor fresh air and the large amount of air from restaurant to kitchen.

The outdoor air is directly discharged from the source by the local smoke exhaust system.

　　局部排氣係統由局部排氣罩、消防成人漫画网站免费管、通風機、粉塵或有害氣體淨化設備和排氣裝置組成。當有害氣體、蒸氣或粉塵較大的工件,而不是方舟在廢氣處理,可以使用一側打開,臉部其他部位封邊排氣罩,或各方不能關閉排氣罩,或上排氣罩、排氣,兩國單方麵排氣和吸氣槽邊吹排氣一切形式。

　　The local exhaust system consists of a local exhaust hood, a fire exhaust pipe, a ventilator, a dust or harmful gas purification device and an exhaust device. When hazardous gas, vapor or dust is larger than the ark in the exhaust gas treatment, you can use one side to open, the other parts of the face to seal the exhaust hood, or the parties can not close the exhaust hood, or the upper exhaust hood, exhaust, unilateral exhaust and suction tank side blowing all forms of exhaust.
