摘　　要：结合拉萨地区气象数据和民居建筑模型,建立多空间太阳能建筑热平衡方程,分析内外墙体传热系数对室内热环境的影响规律,提出了多空间太阳能建筑墙体热工设计方法。结果表明,该方法能够在保证辅助房间温度处于舒适区间的同时,将室内有限的热能尽可能多地分配到主要房间,达到持续提高主要房间温度,兼顾辅助房间温度的目的。当主要房间温度需要达到某一值时,可利用拟合出的函数表达式计算出其相对应的内外墙传热系数。以本文模式c为例,当起居室室内温度设定为14℃,厨房温度为8℃时,其对应的外墙传热系数为0.33 W/(m^2·K),内墙传热系数为1.25 W/(m^2·K),该方法可为被动式太阳能采暖乡村建筑的墙体热工设计提供一定的借鉴。Based on the meteorological data and residential building model in Lhasa area,the heat balance equation to the multi space solar energy building is established,with the influence law of exterior wall heat transfer coefficient on indoor thermal environment analyzed.The results show that the method can maintain the auxiliary room temperature in a comfortable range and the heat distribution of the main room as much as possible to continuously increase the main room temperature and take into account the auxiliary room temperature.When the temperature of the main room needs to reach a certain value,the corresponding heat transfer coefficient of the inner and outer walls can be calculated through the fitted function expression.The results deduced form the model c show that when the indoor temperature of living room is 14℃and the indoor temperature of kitchen is 8 ℃,the corresponding heat transfer coefficient of the exterior wall is 0.33 W/（m^2·K）and the internal wall heat transfer coefficient is 1.25 W/（m^2·K）.The method can be used as a reference for the thermal design of the wall of passive solar heating rural buildings.
