西安市住宅北向封闭阳台内热环境的实测与分析
Thermal environment research of north closing balconies in Xi’an
摘要:
2004年夏季对西安市具有代表性的住宅建筑北向封闭阳台的热环境进行了测试,测试结果表明,除了在夜间外,白天阳台的气温与室外相差不大,都在26 ℃以上,封闭阳台内的热环境较差。通过对封闭阳台在7种不同的保温和围护结构情况下夏季冷负荷的计算对比,认为墙体保温及采用双层窗节能效果显著,并提出了提高其热工性能的一些措施。
Abstract:
Measures thermal environment parameters such as temperature, relative humidity, air velocity and dew point temperature during the summer of 2004. The results show that the temperature in closing balcony is above 26 ℃ in daytime, and less differs with the outdoor temperature except night. Thermal environment in closing balcony is worse. Calculates and compares the cooling loads for test objects with seven kinds of envelope. Considers that the energysaving effect is notable using heat insulating wall and twolayer window in closing balcony. Provides some schemes and methods to improve the thermal environment in closing balconies.
