摘要
概述了被动冷却技术在建筑中的应用方式可按照作用对象的不同分为四类:第一类主要是对建筑物屋顶进行冷却(设置蓄水屋顶、含湿材料、加盖隔热板、设置空气层等);第二类主要是对建筑物墙体进行冷却(在墙体中间设置空间层);第三类主要是对建筑物的窗、玻璃幕、阳台等透光部分进行冷却(设置遮阳、水帘等);第四类主要是对建筑物室内地板进行冷却(建地下室等)。由于建筑物得热的50%来源于建筑物屋顶,所以着重阐述了建筑物屋顶的被动冷却技术。
The applied ways of passive cooling technology in building can be divided into four kinds: the first kind is cooling roof of building (roof pond built, moist material provided, thermal insulation covered, air layer provided); The second kind is cooling wall of building (air layer within wall provided); the third kind is cooling translucent part viz. window, glass wall, balcony (sunshade and water cascade provided); the fourth kind is cooling ground of building (build basement). Heat load in the building may be 50% or more from the roof. Therefore, this paper describes passive cooling technology applied in building roof in detailed.
