热气候风洞内测定种植屋面当量热阻
Measurement of equivalent thermal resistance of planted roof in hot-climate wind tunnel
摘要：
通过控制和调节热气候风洞内的环境参数，分析了广州地区典型气候环境下佛甲草轻型种植屋面的传热过程。通过求解能量平衡方程，得到了该种植屋面材料的外表面综合换热系数和当量热阻，与《夏热冬暖地区居住建筑节能设计标准》中种植屋面的当量热阻基本吻合。

Abstract：
Analyses the heat transfer process of the planted roof in hot-climate wind tunnel in the typical climate condition of Guangzhou by controlling the environment parameters in the wind tunnel. Based on the energy balance equation, calculates the integrated heat transfer coefficient and the equivalent thermal resistance of the planted roof. The result indicates that the equivalent thermal resistance obtained accords with that specified in the Design standard for energy efficiency of residential buildings in hot summer and warm winter zone.
