通風管道是工業與民用建筑的通風與空調工程用金屬或非金屬管道，是為了使空氣流通，降低有害氣體濃度的一種市政基礎設施。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定的界限。遇有個別管段要越界時應與其他工程協商。

Ventilation pipe is a metal or nonmetal pipe for ventilation and air conditioning engineering in industrial and civil buildings. It is a municipal infrastructure for making air circulation and reducing harmful gas concentration. For more complex civil buildings, at the design stage, all kinds of HVAC, water supply and drainage, power supply lighting and building should first negotiate space separation and determine the elevation range of each pipeline. The general case not set himself beyond the boundaries. In case there is a separate section to cross the boundary, we should negotiate with other projects.

解決各種通風管道相碰及協調的原則，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。

To solve all kinds of ventilation pipe collide and coordination principle, generally: "let the pressure get tubular bassoon, no pressure". For example, the water pipe and the wind pipe collide, then the tap water pipe should be turned. The cold and hot water pipes and water pipes together, should change the cold and hot water pipe.

通風管道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，及時發現，將問題解決在安裝之前。為了減少投資，節省空間，降低層高，有些敷設無坡度要求的管道，可以穿梁敷設。

Before the construction of a ventilation pipe, the engineer of the general pipe of the equipment shall draw the lines of the various types of work and the single line on a plane map. Each type of pipe is used with a color pen. In each point of the intersection of its elevation, see if there is any contradiction, timely discovery, the problem is solved before the installation. In order to reduce investment, save space and reduce the height of layers, some pipes that are laid without slope can be laid by beams.

做好工業通風工作，一方面能夠改善生產車間及周圍的空氣條件，防止職業病的產生、保護人民健康、提高勞動生產率；

Doing well in industrial ventilation can improve the air condition of production workshop and surrounding area, prevent occupational disease, protect people's health and increase labour productivity.

另一方面可以保證生產正常運行，提高產品質量。隨著工業的不斷發展，散發的工業有害物的種類和數量日益增加，大氣污染已經成為了一個全球性的問題。如何做好工業通風，職業健康管理以及環境保護是我們工作人員的意向重要職責。通過本周的工業通風與除塵大作業的學習，學會通風管道系統的設計計算，了解通風管道系統包括通風除塵管道、空調管道等，是通風除塵和空氣調節系統的重要組成部分，它把通風進風口，空氣的熱濕及凈化處理設備，送排風口，部件和風機連成一個整體，使之有效運轉。

On the other hand, it can ensure the normal operation of the production and improve the quality of the product. With the continuous development of industry, the variety and quantity of industrial hazardous materials are increasing, and air pollution has become a global problem. How to do a good job of industrial ventilation, occupational safety and health management and environmental protection is an important duty of our safety staff. Through this week's industrial ventilation work study, design and calculation to ventilation system, ventilation system including understanding ventilation duct, air duct, is an important part of ventilation and air conditioning systems, the ventilation air inlet, air heat and moisture and purification equipment, supply and exhaust the air blower, and parts into a whole, and make it work efficiently.
