        關于通風管道的送風方式

        來源:http://www.boursomarket.com 日期:2021-01-15 發布人:gaoshitongferng

        通風管道是特地為一處或幾處房間或設備送風和排風的管道。排煙管道是特地共排煙氣的管道,就用途來講有分別,就管道自身講都是管道。 裝置完的風管要保證外表潤滑干凈,室外風管應有防雨、防雪措施。 風管伸入構造風道時,其末端應裝置上鋼板網,避免系統運轉時,雜物進入金 屬風管內。金屬風管與構造風道縫隙應封堵緊密。
        Ventilation duct is a kind of duct specially used to supply and exhaust air for one or several rooms or equipment. The smoke exhaust pipe is a pipe specially designed to exhaust smoke. It is different in terms of use, and it is a pipe in terms of the pipe itself. The air duct after installation shall be lubricated and clean, and the outdoor air duct shall be provided with rain proof and snow proof measures. When the air duct extends into the structural air duct, steel mesh shall be installed at the end of the air duct to prevent the sundries from entering into the metal air duct during the operation of the system. The gap between metal air duct and structural air duct should be sealed tightly.
        風管穿越沉降縫時應按設計請求加設套管,套管與風管的間隙用填料(軟質)封 堵緊密,從這些特性我們應該能夠很快的辨別開兩者的區別。
        When the air duct passes through the settlement joint, the casing should be added according to the design requirements, and the gap between the casing and the air duct should be tightly sealed with filler (soft). From these characteristics, we should be able to quickly distinguish the difference between the two.
        廚房室內的管道布置要遵循“短”原則,少用彎頭,尤其是大角度彎頭,這種布管方式和空調的“橫豎整齊”有所不同,目的是保障排油煙效果,還可以節省。煙罩上面的集氣管的主出口 煙罩的中部位置。
        The pipeline layout in the kitchen should follow the "short" principle, and use less elbows, especially large angle elbows. This kind of pipe layout is different from the "vertical and horizontal neat" of the air conditioner, so as to ensure the effect of exhaust fumes and save energy. The central position of the main outlet hood of the air collecting pipe above the hood.
        廚房所在建筑物高度小于等于15m時,油煙排放口應高出屋頂。原則上要高出建筑物2m以上。建筑物高度大于15m時,油煙排煙口高度應大于15m。
        When the height of the building where the kitchen is located is less than or equal to 15m, the oil fume outlet shall be higher than the roof. In principle, it should be more than 2m higher than the building. When the height of the building is more than 15m, the height of the oil smoke outlet should be more than 15m.
        排風管的室外排氣口上應安裝受室外風壓影響小的管帽(管罩)制成品。按換氣次數確定排風量。各家廚房差別較大,廚房面積與廚具、爐灶的數量不成正比,同樣灶的產生的污染物和熱量也 差別很大。
        The outdoor exhaust outlet of the exhaust pipe shall be installed with the pipe cap (pipe cover) which is less affected by the outdoor wind pressure. Determine the exhaust volume according to the ventilation frequency. The kitchen area is not directly proportional to the number of kitchenware and stoves, and the pollutants and heat produced by the same stoves are also very different.
        實際上廚房通風并非是全面通風,按換氣次數設計風量會有很大的誤差。
        In fact, kitchen ventilation is not comprehensive ventilation, according to the number of ventilation design air volume will have a great error.
