对通风管道进行保温需要注意什么？

当通风管道运送高温气体时，为什么要进行保温呢?其实是为了避免管道内空气热损失，还可以阻挠热量散发到房间内让室温升高，避免人接触风道被烫伤。在夏日因运送气体温度低于周围环境空气露点温度，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，生活中的重要性大家都知道，尤其是一些人在购房时也会考虑一下通风效果怎么样。

Why do we need insulation when transporting high-temperature gas through ventilation ducts? In fact, it is to avoid heat loss in the air inside the pipeline, and also to prevent heat from dissipating into the room, causing room temperature to rise and preventing people from being scalded by contact with the air duct. In summer, the temperature of the transported gas is lower than the dew point temperature of the surrounding air, causing condensation on the outer wall of the pipeline. The air ducts of the centralized air conditioning system will increase the loss of cooling capacity, and condensation droplets together will pollute the ceiling and walls, so cold insulation treatment should also be carried out. In fact, the importance of ventilation duct installation in daily life is well-known, especially when purchasing a house, some people will also consider the ventilation effect.

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 stages of building, the position of each pipeline will be designed, and the ventilation equipment will ensure that people have an outstanding quality of life. Over time, it will rust and age, which also reminds the management of high-rise buildings to regularly organize pipelines and extend their service life. Sometimes, for special ventilation pipes, anti-corrosion coatings are used for anti-corrosion protection. When using coatings, the pipes should be cleaned and evenly coated 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)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, during the design phase of ventilation ducts, various professions (HVAC, water supply and drainage, power supply and lighting) should negotiate space separation and determine the elevation and scale of each type of duct. Under normal circumstances, one should not exceed the limits set for oneself. When a single pipe section needs to cross the boundary, it should be negotiated with other projects. The air ducts in the ventilation system are interconnected as a whole and must follow the resistance balance rules of each branch. Once the structural mode and pipeline scale 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.
