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.

在夏日因運送氣體溫度低于周圍環境空氣溫度，管道外壁會結露。這對會集空調系統的風道會加大冷量損失，一起凝結水滴會污染吊頂和墻地面，因而也應該進行保冷隔熱處理，其實關于通風管道裝置施工來說，咱們生活中的重要性咱們都知道，尤其是一些人在購 房時也會考慮一下通風效果怎么樣。

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.

濟南通風管道

Jinan ventilation pipe

房子在構建初期就會設計好各管道的位置，通風設備為人們具有杰出的生活品質做保障用的時刻長了就會生銹發生老化表象，所以也是提醒著高樓的管理人員經常性的整理管道，延伸運用的壽數。有時分關于一些特別的通風管道:會選用噴防腐涂料進行防腐保護，在運用涂料的時分，要先將管道整理潔凈，在均勻的涂上涂料進行防腐。

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.

對于民用建筑，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。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。

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.
