The ventilation system of shopping malls increases heat dissipation in the body and prevents discomfort caused by wet skin. This kind of ventilation can be called thermal ventilation. When the indoor temperature is higher than the outdoor temperature, the building components will be cooled. This kind of ventilation is called building cooling ventilation. So, what role does the ventilation duct play in it?

首先是空氣是人們生活中重要的，缺少了空氣人們就會感到窒息活不下去，空氣中的氧氣也是維持人的生命基本的要素，所以要時刻保持著室內的通風，滿足人們對于氧氣的需求，這也是通風管道對于人們生活的作用。在人群密集或者相對于封閉的空間中空氣的不流通、呼出的二氧化碳等等都會使得空氣不流通，所以要時刻記得通風，尤其是在工廠中更要注意。

First of all, air is important in people's life. Without air, people will feel suffocated and can't live. Oxygen in the air is also the basic element to maintain people's life. Therefore, we should always maintain indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipes in people's life. In crowded or closed spaces, the lack of air circulation, exhaled carbon dioxide and so on will make the air not circulating, so always remember to ventilation, especially in factories.

其次是通風管道的使用可以使得良好的通風，室內的空氣流通，控制氣流的速度，什么叫做通風，也就是將室內或者是封閉空間里的污濁的空氣排出去，在工廠中將產生的有害物質都經過凈化處理之后都排出室外，然后再將新鮮空氣送入室內，稀釋空氣的有害物質，滿足人們對于空氣的需求。

It is also called to control the ventilation speed of the indoor air, which can dilute the harmful substances in the indoor air. Secondly, it is called to control the ventilation speed of the indoor air, and then exhaust the polluted air in the indoor space, which can meet the needs of people.

就是通風管道保持空氣的流通，讓人們能夠呼吸到新鮮的空氣，這也是為人們的身體著想，通風管道在樓房建筑中都有著廣泛的應用，讓室內的空氣更加的流暢。

It is the ventilation duct that keeps the air circulating so that people can breathe fresh air, which is also for the sake of people's body. Ventilation duct is widely used in buildings and buildings to make the indoor air more smooth.
