Abstract:
夜间通风是一种同时利用自然通风与围护结构蓄热的间歇通风降温方式。夜间引入的低温空气一方面通过通风换气的方式带走室内的热量,另一方面可以冷却建筑构件,将冷量蓄存这些构件中。这可以降低白天房间的最高室温、缓解了建筑的降温负荷, 对提高室内热舒适性有显著效果。本文从夜间通风降温的原理入手,对其主要研究领域,包括气候潜力、降温参数分析、通风换气、对流换热、围护结构蓄热、夜间通风的构造等进行了深入的文献研究,在此基础上归纳出夜间通风的研究体系。最后,对目前国内外的研究现状和存在问题进行了总结。
Note:
Night ventilation is a kind of intermittent ventilation way which coupled the effect of natural ventilation and thermal mass of envelope. The introduced cool air can take away the heat in the indoor air by the way of ventilation, and also can cool down the components and storage heat in the building envelope. This has a significant effect on reducing maximum room temperature, alleviating cooling load during daytime and improving indoor thermal comfort. The present paper started with the principle of night ventilation, and conducted in-depth literature study about the research field of night ventilation including climate potential, cooling parameter analysis, ventilation, convection heat transfer, heat storage of building envelope, as well as construction of night ventilated building. Based on this study, the research system about night ventilation was summarized. The status in quo and the main problem about night ventilation research were proposed at last of the paper.
