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.

當通風管道運送高溫氣體時，為什么要進行保溫呢?先是避免管道內空氣熱損失，還可以阻撓熱量散發(fā)到房間內讓室溫升高，避免人接觸風道被燙傷。

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.

在夏日因運送氣體溫度低于周圍環(huán)境空氣露點溫度，管道外壁會結露。這對會集空調系統(tǒng)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 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.

房子在構建初期就會設計好各管道的位置，叁金來通風設備為人們具有杰出的生活品質做保障

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。

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.
