北京地区临时建筑围护结构改造实验研究
Experimental Study on Renovation of Temporary Building Envelope Structures in Beijing Area
摘要
Abstract
Using two single story temporary buildings without air conditioning installed in Yanqing District,Beijing as experimental objects,energy-saving renovation was carried out on the enclosure structure,and the effects of roof,floor,exterior window and roof sprinkler renovation on the indoor thermal environment in summer were compared.After replacing with a blue waterproof roof with eaves,the indoor temperature of the temporary building decreases at noon due to the shading effect of the eaves.Improving the thermal in-sulation and air tightness of the floor is not conducive to improving the indoor thermal environment in sum-mer.Reducing the area of exterior windows and attac-hing Low-E film can help improve the indoor thermal comfort in summer.When the solar irradiance is high,the effect of roof spraying on reducing the indoor tem-perature is obvious.When the solar irradiance is low,the effect of roof spraying on reducing the indoor tem-perature is not obvious.Under similar outdoor environ-mental conditions,compared to before the energy-sav-ing renovation,the indoor temperature of temporary buildings after the energy-saving renovation is de-creased by 11.3 ℃,a decrease of 24.6％.The ener-gy-saving renovation of temporary buildings and the in-troduction of passive technology can effectively reduce indoor temperature in summer and improve the thermal comfort.关键词
