某大礼堂自然通风热舒适性分析

Thermal Comfort Analysis of Natural Ventilation for An Auditorium

科学合理地利用自然通风可提高室内空气品质、减少建筑能耗,并能保证一定的热舒适性。理论分析了自然通风热压作用下某大学建于20世纪30年代大礼堂的通风量、通风路径和人体热舒适性情况。结果表明,热压作用下的中和面高度变化较小,气流流向稳定,在非极端气候下,通风量大,室内的热舒适性及空气品质良好。一些经典建筑的设计理念在现代技术的帮助下,依然能够为现代节能建筑所参考。

Natural ventilation can improve the indoor air quality and thermal comfort with building energy saving mode in specific weather condition.It analyzed in theory that the flow rate,ventilation path and thermal comfort feelings of people in a thermal ventilation au ditorium building in a university,which was built in the 1930s.The results showed that owing to the thermal effect,the height of the neutral level without obvious changes and steady air flow can be achieved,as well as the high flow rate,well indoor thermal comfort and air quality in non-extreme weather.With the help of modern technology,some classical architectural design concept is still able to modern energy-efficient buildings reference.
