建筑外窗耐候性能检测技术研究

Research on Testing Technology of Weather-proof Performance of Exterior Windows in Buildings

建筑外窗作为建筑围护结构的重要组成部分,性能的优劣直接关系到建筑室内热舒适及建筑能耗水平。目前我国建筑外窗的性能指标都是在单一气候条件下对单一性能的评价,而在实际使用过程中外窗性能是受综合气候条件的变化影响。本文考虑外窗在综合气候条件作用下的环境,研制外窗的耐候性能检测设备,通过测试外窗在综合气候条件下的耐候性能,提出对外窗性能更合理的评价。

Exterior building windows form an important part of building protected structure and its performance is directly related to indoor thermal comfort and building energy consumption level. At present, the performance index of exterior building window in our country is single performance evaluation under single climate condition, but it fails to take into account external window in the actual use of the process, window performance is affected by the change of comprehensive climatic conditions. In this paper, by considering the effect of the external window on the climate, weather-resistance testing equipment for external windows is developed through test of the weather-proof performance of the external window under comprehensive climate factors. The paper puts forward a more reasonable evaluation of external window performance.
