通風管道主要應用在工業(yè)及建筑工程中，應用領域主要涉及：電子工業(yè)無塵廠房凈化系統(tǒng)，醫(yī)藥食品無菌車間凈化系統(tǒng)，酒店賓館、醫(yī)院、工廠及寫字樓的空調(diào)系統(tǒng)，工業(yè)污染控制用除塵、排煙、吸油等排風管、工業(yè)環(huán)境或崗位舒適用送風管、煤礦抽放瓦斯用抽放瓦斯系統(tǒng)、煤礦礦井環(huán)境控制用送回風系統(tǒng)等等;
The ventilation pipe is mainly used in industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, with the addition of dust, smoke and fume exhaust pipe, etc. industrial environment comfortable by feeding or post the wind pipe, coal mine gas drainage in coal mine gas drainage system, environmental control system, industrial pollution control air supply;
1)對于比較復雜的民用建筑，在設計階段，各工種(暖通、給水排水，供電照明與建筑)應協(xié)商好空間分隔，定出每種管道的標高范圍。一般情況下不得越出給自己規(guī)定的界限。遇個別管段要越界時應與通風管道其他工程協(xié)商。
1) for more complex civil buildings, in the design phase, the various types of work (HVAC, water supply, drainage, power supply lighting and building professional) should first negotiate space separation, determine the elevation of each pipe range. The general case not set himself beyond the boundaries. In case of crossing the section, consult the other works of the ventilation pipe.
2)解決各種通風管道相碰及協(xié)調(diào)的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改變冷、熱水管道。
2) to solve all kinds of ventilation pipe collision and coordination principle, generally: "let the pressure get tubular bassoon, no pressure". For example, when the water pipe is in collision with the air pipe, the water pipe should be turned. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.
3)施工前應設備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標高，看是否有矛盾之處，及時發(fā)現(xiàn)，將問題解決在安裝之前。
3) the engineer of the equipment main shall, before construction, draw the lines of each type of work on a single plan. Each pipe uses a color pen. At the intersection of each of its elevation, to see if there are inconsistencies, timely discovery, the problem before the installation.
4)為了減少投資，節(jié)省空間，降低層高，有些敷設無坡度要求的管道，可以穿梁敷設(如自來水管道，消防噴灑干管等)。
4) in order to reduce investment, save space and reduce storey height, some laying pipelines without slope requirements can be laid through beams (such as water pipes, fire fighting, dry pipes, etc.).
