1. Ventilation piping design shall be carried out according to the site, structure and environment required for installation of the ventilation pipe to ensure the practicability of the ventilation duct.

　　2、一般送排風系統和空調系統的通風管道安裝，需在建筑物的屋面做完，安裝部位的障礙物已涪理干凈的條件下進行。

　　2, general ventilation pipe ventilation system and air conditioning system installation, should be done in the roof of a building, the obstacle of the installation part has disposal of clean conditions.

　　3、一般除塵系統通風管道安裝，需在廠房內與風管有關的工藝設備安裝完畢，設備的接管或吸、排塵罩位置已定的條件下進行。

　　3, general dust removal system ventilation pipe installation, need to be in the workshop with the wind pipe related process equipment installation, equipment take over or suction and dust discharge hood position has been set under the conditions.

　　4、施工準備工作已做好，如施工工具、吊裝機械設備、必要的腳手架或升降安裝平臺已齊備施工用科已能滿足要求。

　　4, construction preparation work has been done, such as construction tools, hoisting machinery and equipment, necessary scaffolding or lifting installation platform has been completed, construction section has been able to meet the requirements.

　　5、要與土建施工密切配合，應預圖的安裝孔洞，預埋的支架構件均已完好，并經檢查符合設計要求。

　　5, to work closely with the civil construction, should be pre installed holes, the pre embedded support components are intact, and checked to meet the design requirements.

　　6、通風及空調系統管路組成的各種通風管道、部件、配件均已加工完畢，并經質量檢查合格。

　　6, ventilation and air conditioning systems composed of a variety of ductwork, parts and fittings have been processed, and the quality inspection qualified.

　　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。

　　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 a paragraph is crossed, consult with other projects.

　　2)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。

　　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，及時發現，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.).
