The ventilation duct is used to ventilate, alleviate indoor air quality and transport fresh air. Since air is the living condition of people, it will suffocate people to stay in the closed air frequently. The following installation of ventilation duct tells you the precautions in the use of ventilation duct.

當(dāng)通風(fēng)管道運(yùn)送高溫氣體時(shí)，為什么要進(jìn)行保溫呢?先是避免管道內(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(fēng)道被燙傷。

When the ventilation pipe carries high-temperature gas, why should it be insulated? First, avoid the heat loss of the air in the pipe, prevent the heat from being radiated into the room, raise the room temperature, and prevent people from being scalded when contacting the air duct.

在夏日因運(yùn)送氣體溫度低于周圍環(huán)境空氣露點(diǎn)溫度，管道外壁會(huì)結(jié)露。這對(duì)會(huì)集空調(diào)系統(tǒng)的風(fēng)道會(huì)加大冷量損失，一起凝結(jié)水滴會(huì)污染吊頂和墻地面，因而也應(yīng)該進(jìn)行保冷隔熱處理，其實(shí)關(guān)于通風(fēng)管道裝置施工來(lái)說(shuō)，咱們生活中的重要性咱們都知道，尤其是一些人在購(gòu)房時(shí)也會(huì)考慮一下通風(fēng)效果怎么樣。

In summer, because the temperature of the transported gas is lower than the dew point temperature of the surrounding air, the outer wall of the pipeline will condense. This will increase the cooling loss of the air duct of the centralized air conditioning system, and the condensed water droplets will pollute the ceiling and wall and ground, so the cold insulation treatment should also be carried out. In fact, we all know the importance of the construction of ventilation duct devices in our life, especially some people will consider the ventilation effect when buying a house.

房子在構(gòu)建初期就會(huì)設(shè)計(jì)好各管道的位置，叁金來(lái)通風(fēng)設(shè)備為人們具有杰出的生活品質(zhì)做保障

At the beginning of the construction of the house, the location of each pipeline will be designed, and sanjinlai ventilation equipment will ensure people's excellent quality of life

用的時(shí)刻長(zhǎng)了就會(huì)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(yùn)用的壽數(shù)。有時(shí)分關(guān)于一些特別的通風(fēng)管道:會(huì)選用噴防腐涂料進(jìn)行防腐保護(hù)，在運(yùn)用涂料的時(shí)分，要先將管道整理潔凈，在均勻的涂上涂料進(jìn)行防腐。

It will rust and aging after a long time, so it also reminds the managers of high-rise buildings to regularly tidy up the pipes and extend the service life. Sometimes it is about some special ventilation pipes: spraying anti-corrosion paint will be selected for anti-corrosion protection. When applying paint, the pipes should be cleaned first and evenly coated for anti-corrosion.
