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、空调体系：通风管道可内贴保温材料，表面美观。

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

二、排油烟体系：饭店、酒楼、宾馆的厨房均有很多油烟发生，需求排出，采用通风管道是适宜的，强度好，经济实用。

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、除尘体系：除尘装置的搜集和运送，可运用通风管道。

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

通风管道在设计阶段，各工种(暖通、给水排水，供电照明)首先应洽谈好空间分隔，定出每种管道的标高规模。一般状况下不得越出给自己规定的界限。遇有单个管段要越界时应与其他工程洽谈。

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.

在通风体系中的风管是相互连接的一个整体，必然得遵从各支路阻力平衡规则，当风管体系的结构方式、管道尺度一经确认，在风机作用下，各段的风量是按阻力平衡规则自动分配的。

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.

使用通风管道的规划原理和计算方法，剖析车间降温管道的安置，所以，车间的降温管道是否规划的合理，直接影响到了整个车间降温工程的作用，所以车间的降温管道的各种问题十分重要的。

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.
