Generally speaking, the flow of the ventilation system is very large, so it is necessary to use the air delivery pipe with small resistance to save the cost and operation cost. Generally, galvanized iron pipe is used, and stainless steel pipe is used in corrosive and especially humid places.

一、空調體系：通風管道可內貼保溫材料，表面美觀。

1、 Air conditioning system: the ventilation pipe can be pasted with thermal insulation material, with beautiful surface.

二、排油煙體系：飯店、酒樓、賓館的廚房均有很多油煙發生，需求排出，采用通風管道是適宜的，強度好，經濟實用。

2、 Exhaust system: there are a lot of lampblack in the kitchens of hotels, restaurants and hotels, which need to be discharged. It is appropriate to use ventilation pipes with good strength, economy and practicality.

三、除塵體系：除塵裝置的搜集和運送，可運用通風管道。

3、 Dust removal system: the collection and transportation of dust removal devices can use ventilation pipes.

通風管道在設計階段，各工種(暖通、給水排水，供電照明)首先應洽談好空間分隔，定出每種管道的標高規模。一般狀況下不得越出給自己規定的界限。遇有單個管段要越界時應與其他工程洽談。

In the design stage of ventilation duct, each type of work (HVAC, water supply and drainage, power supply and lighting) should first discuss the space separation, and determine the elevation scale of each type of duct. In general, they should not go beyond the limits set for themselves. When a single pipe section needs to cross the boundary, it shall negotiate with other projects.

在通風體系中的風管是相互連接的一個整體，必然得遵從各支路阻力平衡規則，當風管體系的結構方式、管道尺度一經確認，在風機作用下，各段的風量是按阻力平衡規則自動分配的。

In the ventilation system, the air duct is an interconnected whole, which must comply with the resistance balance rules of each branch. When the structure mode and pipe size of the air duct system are confirmed, the air volume of each section is automatically distributed according to the resistance balance rules under the action of the fan.

使用通風管道的規劃原理和計算方法，剖析車間降溫管道的安置，所以，車間的降溫管道是否規劃的合理，直接影響到了整個車間降溫工程的作用，所以車間的降溫管道的各種問題十分重要的。

By using the planning principle and calculation method of ventilation pipe, this paper analyzes the placement of cooling pipe in workshop. Therefore, whether the cooling pipe in workshop is planned reasonably directly affects the effect of the whole workshop cooling project, so various problems of cooling pipe in workshop are very important.
