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。
Building exterior windows as an important part of building envelope structure, the merits of the performance directly related to the indoor thermal comfort and building energy consumption level. At present, the performance indexes of exterior windows in our country are the evaluation of single performance under the single climatic conditions, while the external window performance is affected by the change of the comprehensive climatic conditions during the actual use. In this paper, we consider the environment of the outer window under the condition of the comprehensive climatic conditions, develop the weatherability test equipment of the outer window, and put forward the more reasonable evaluation of the outer window performance by testing the weatherability of the outer window under the comprehensive climatic conditions.
