With the rapid development of urban rail transit, passengers' requirements for the riding environment are also increasing. In this context, roof ventilation sunroofs, as an important facility to improve air quality and passenger comfort, have also been widely used in the field of rail transit.
The ventilation skylight realizes natural ventilation by using the thermal pressure and wind action formed by the temperature difference between indoor and outdoor. In rail transit buildings, the ventilated sunroof can not only effectively eliminate indoor odors and dirty air, but also introduce fresh outdoor air into the car, providing passengers with a healthier and more comfortable riding environment. At the same time, the application of lighting and ventilation skylights greatly increases the indoor natural lighting area and improves the brightness of the station.
In addition, the ventilation and lighting skylight also has good environmental performance. By making the most of natural light and air circulation, the reliance on electric lighting and air conditioning equipment is reduced, resulting in lower energy consumption and carbon emissions.
In practical application, for example, McWeig's Chengdu Metro Line 27 project uses a 10A thin ventilation and lighting skylight, Kunming West Railway Station project uses a 10B thin ventilation and lighting skylight, and Guangzhou Rail Transit Line 7 project uses a round arch side to open a wind and light skylight.
In summary, the application of roof ventilation sunroof in the field of rail transit not only improves the air quality in the car, but also improves the comfort of passengers.
