When the ventilation pipe carries high temperature gas, why heat preservation? The first is to avoid the heat loss of the air in the pipe. It can also prevent the heat from radiating into the room, let the room temperature rise, and prevent people from being scalded when contacting the air duct.

在夏日因运送气体温度低于周围环境空气温度，管道外壁会结露。这对会集空调系统的风道会加大冷量损失，一起凝结水滴会污染吊顶和墙地面，因而也应该进行保冷隔热处理，其实关于通风管道装置施工来说，咱们生活中的重要性咱们都知道，尤其是一些人在购 房时也会考虑一下通风效果怎么样。

In summer, because the temperature of the gas transported is lower than that of the ambient air, the outer wall of the pipeline will be dewed. This will increase the cooling loss of the air duct of the centralized air conditioning system, and the condensation water droplets will pollute the ceiling and the wall floor, so the cold insulation treatment should also be carried out. In fact, we all know the importance of the ventilation duct installation construction in our life, especially when some people buy a house, they will also consider how the ventilation effect is.

房子在构建初期就会设计好各管道的位置，通风设备为人们具有杰出的生活品质做保障用的时刻长了就会生锈发生老化表象，所以也是提醒着高楼的管理人员经常性的整理管道，延伸运用的寿数。有时分关于一些特别的通风管道:会选用喷防腐涂料进行防腐保护，在运用涂料的时分，要先将管道整理洁净，在均匀的涂上涂料进行防腐。

In the early stage of building, the location of each pipe will be well designed, and the ventilation equipment will be used to guarantee people's outstanding quality of life. After a long time, it will rust and appear aging. Therefore, it is also a reminder to the management personnel of high-rise buildings to regularly sort out the pipes and extend the service life. Sometimes about some special ventilation pipes: spray anti-corrosion paint for anti-corrosion protection. When using the paint, clean the pipe first, and evenly apply the paint for anti-corrosion.

对于民用建筑，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。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。

For civil buildings, in the design stage of ventilation pipes, all kinds of work (HVAC, water supply and drainage, power supply and lighting) should first discuss the space separation, and determine the elevation scale of each kind of pipe. 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. 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.
