當通風管道運送高溫氣體時，為什么要進行保溫呢?其實是為了避免管道內(nèi)空氣熱損失，還可以阻撓熱量散發(fā)到房間內(nèi)讓室溫升高，避免人接觸風道被燙傷。在夏日因運送氣體溫度低于周圍環(huán)境空氣露點溫度，管道外壁會結(jié)露。這對會集空調(diào)系統(tǒng)的風道會加大冷量損失，一起凝結(jié)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，生活中的重要性大家都知道，尤其是一些人在購房時也會考慮一下通風效果怎么樣。

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(zhì)做保障用的時刻長了就會生銹發(fā)生老化表象，所以也是提醒著高樓的管理人員經(jīng)常性的整理管道，延伸運用的壽數(shù)。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 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.

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)應洽談好空間分隔，定出每種管道的標高規(guī)模。一般狀況下不得越出給自己規(guī)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(guī)則，當風管體系的結(jié)構方式、管道尺度一經(jīng)確認，在風機作用下，各段的風量是按阻力平衡規(guī)則自動分配的。

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.
