普通中空玻璃外窗对室内光热环境的影响

在夏热冬冷地区，我国现在执行节能50％的设计标准，新建建筑已大量使用普通中空玻璃外窗，但是关于这种窗对室内环境影响的研究还不多。该文研究了普通中空玻璃窗对室内热环境和光环境的影响。在杭州夏季，对安装了普通中空玻璃外窗的试验房室内的热环境参数（温度、相对湿度、热舒适指标PMV—PPD）和光环境参数照度进行了测定。测定结果表明，试验房室内PMV值在-0．7至07之间的时间在50％左右，热舒适性欠佳，但工作区域照度均大于110 lx，能够满足室内人员的自然光照明需求。

Influence of Double Glass Windows on Indoor Thermal and Light Environments

This article studies the influences of windows with double glass on indoor thermal and light environments. The author determines indoor thermal environment parameters, including air temperature, relative humidity, and PMV-PPD, and light environment parameters in an experimental house with double glass window in Hangzhou summer. The results show that the percentage of PMV values within -0.7-0.7 is about 50% in the test room, and thermal comfort is poor, however the illumination in working place is beyond 110 Ix, which could satisfy the requirement for daylight illumination.
