        山東通風管道教你認識氣幕!

        氣幕空氣以必定速度從條縫形孔口噴出時,構成一股平面射流。如在其對面設置條縫形吸風口吸入這股氣流,在吹、吸風口之間就會構成一道象帷幕一樣的氣流。運用這種吹吸氣流自身所具有的動量間隔氣流兩側空氣的安裝稱為氣幕。
          When the air curtain air is ejected from the slotted orifice at a certain speed, it forms a plane jet. If a slit suction port is set on the opposite side to inhale the air flow, a curtain-like air flow will be formed between the blowing and suction ports. The installation of the momentum interval air on both sides of the air flow with this blowing and sucking air flow is called the air curtain.
          裝設在建筑物進出口的氣幕稱為大門空氣幕。大門空氣幕能夠避免室外風、灰塵、昆蟲、污染空氣和臭味侵入室內,添加建筑物的熱(冷)損失落,而且無妨礙人和物的經由。大門空氣幕在人員車輛進出一再的工業廠房、冷藏庫、百貨公司、劇院等處獲得了普及運用。在民用建筑中大多采用上部送風的上送式,在工業建筑中多采用下送式和側送式。氣幕也用于部分地址節制污染物松散,作為這種用處的安裝稱為氣幕間隔或吹吸式排風罩,在大型酸洗槽、鍛造車間落砂和大型工件油漆等出產進程中已良多采用。與傳統的部分排風罩比擬,它的動力耗費少,污染節制結果好,無妨礙出產操作。
          The air curtain installed at the entrance and exit of the building is called the door air curtain. The door air curtain can prevent outdoor wind, dust, insects, polluted air and odor from intruding into the room, add heat (cold) loss to the building, and do not hinder the passage of people and things. The door air curtain has been widely used in industrial factories, refrigeration stores, Department stores, theatres and other places where people and vehicles come in and out repeatedly. In civil buildings, the upper air supply is mostly used, while in industrial buildings, the lower air supply and side air supply are mostly used. Air curtain is also used to control loose pollutants at some sites. As an installation for this purpose, it is called air curtain interval or Blow-Suction exhaust hood. It has been widely used in the production process of large pickling tank, sand drop in forging workshop and paint for large workpieces. Compared with the traditional part of the exhaust hood, it has less power consumption, good pollution control results and no obstruction to production operation.
          風的大小和傾向是不時改動的,因此自然通風的通風結果不不變。然則自然通風不用耗動力,是一種經濟的通風辦法。
          The size and tendency of the wind change from time to time, so the ventilation result of natural ventilation remains unchanged. However, natural ventilation does not consume power and is an economical ventilation method.
