　　目前通風(fēng)管道在工業(yè)與民用建筑的方面發(fā)揮了重要作用，特別可以使空氣流通，降低有害氣體濃度，作用體現(xiàn)非常明顯。下面一起具體了解一下吧。

At present, ventilation ducts play an important role in industrial and civil buildings, especially in promoting air circulation and reducing the concentration of harmful gases, and their effects are very evident. Let's take a closer look together.

　　通風(fēng)，就是將室內(nèi)或者是封閉空間里的污濁的空氣排出去，在工廠(chǎng)中將產(chǎn)生的有害物質(zhì)都經(jīng)過(guò)凈化處理之后都排出室外，然后再將新鮮空氣送入室內(nèi)，稀釋空氣的有害物質(zhì)，滿(mǎn)足人們對(duì)于空氣的需求。

Ventilation is the process of removing polluted air from indoor or enclosed spaces, purifying the harmful substances produced in factories and discharging them outdoors. Fresh air is then sent indoors to dilute the harmful substances in the air and meet people's air needs.

　　保持新鮮的空氣流通很重要，這也是通風(fēng)管道對(duì)于人們生活的作用。在人群密集或者相對(duì)于封閉的空間中空氣的不流通、呼出的二氧化碳等等都會(huì)使得空氣不流通，所以我們會(huì)用到尤其是在工廠(chǎng)中更要注意。

Maintaining fresh air circulation is important, which is also the role of ventilation ducts in people's lives. The lack of air circulation and exhaled carbon dioxide in densely populated or enclosed spaces can lead to poor air circulation, so we need to pay more attention, especially in factories.

　　通風(fēng)管道主要應(yīng)用在工業(yè)及建筑工程中，應(yīng)用領(lǐng)域主要涉及：電子工業(yè)無(wú)塵廠(chǎng)房?jī)艋到y(tǒng)，醫(yī)藥食品無(wú)菌車(chē)間凈化系統(tǒng)，酒店賓館、商場(chǎng)醫(yī)院、工廠(chǎng)及寫(xiě)字樓的中央空調(diào)系統(tǒng)，工業(yè)污染控制用除塵、排煙、吸油等排風(fēng)管、工業(yè)環(huán)境用送風(fēng)管、煤礦抽放瓦斯用抽放瓦斯系統(tǒng)、煤礦礦井環(huán)境控制用送回風(fēng)系統(tǒng)等；常被影視、動(dòng)漫中開(kāi)發(fā)成逃生及潛入專(zhuān)用路線(xiàn)。

Ventilation ducts are mainly used in industrial and construction engineering, and their application areas mainly involve: purification systems for electronic dust-free factories, purification systems for sterile pharmaceutical and food workshops, central air conditioning systems for hotels, shopping malls, hospitals, factories, and office buildings, exhaust pipes for dust removal, smoke exhaust, oil suction, etc. for industrial pollution control, air supply pipes for industrial environments, gas drainage systems for coal mines, and supply and return air systems for coal mine environmental control; Often developed as a dedicated route for escape and infiltration in movies, TV shows, and anime.
