拉萨多层被动太阳能住宅热环境测试研究
Measurement of thermal environment in a multistoried passive solar residence in Lhasa
摘要：
拉萨地区城市多层住宅的南向外墙多设置大面积外窗或封闭阳台，形成事实上的被动太阳房。对此类典型建筑的室内热环境和室外气象条件进行了测试，发现在室外温度为0 ℃、日照时间内太阳总辐射平均照度为0.45 kW/m2左右的条件下，建筑室内最低温度在14 ℃以上，平均温度在15～16 ℃之间，可满足基本的人体热舒适要求；窗帘的开启与关闭对室内最低温度影响不大，但对平均温度有明显影响；南向外墙开设大面积外窗夏季并不会造成室内过热。
Abstract：
The setting of large exterior windows or closed balcony in south walls of multistoried residences in Lhasa actually serves as passive solar houses do. Tests the indoor thermal environment and outdoor temperature for this kind of typical building. The results indicate that when the outdoor temperature is about 0 ℃ and the average solar radiant intensity is about 0.45 kW/m2, the minimal and average indoor temperature of this building can reach up to about 14 ℃ and 15~16 ℃ respectively, which can meet the basic demand of human thermal comfort; that the effect of curtain opening or closing is not remarkable to the minimal indoor temperature but obvious to the average indoor temperature; and that the over heat is not found in summer.
