特朗勃集热墙在蒙古国“极寒学校”中的应用与节能实效研究

Trombe Wall Applied in Mongolia Cool School and Energy-efficient Effect

集热蓄热墙是一种有效利用太阳能进行供暖的设计,在全球能源危机的背景下,被动式太阳房在建筑节能领域正得到广泛应用。以蒙古国寒区学校为例,从热工角度分析集热墙的工作原理、传热方式,计算围护结构得热失热和建筑年采暖热耗值,比较不同材料的蓄热性能及应用特朗勃墙被动式集热设计的节能实效。针对严寒地区的气候特征,剖析其热环境调节策略,以期对被动式太阳能技术的推广产生积极意义。

Trombe wall is an efficient method for heating design under the background of global energy crisis. Nowadays, the passive solar-house is the mainstream of the development of energy-saving building development. In this paper, Taking the Mongolia cool school design competition winner as an example, From the thermal point of view, we analyze the operating principle, and heat transfer mode of the heat collecting wall, calculate heat gain ＆ loss of building envelope and the annual heating energy consumption value. We also compare the thermal storage performance of different materials and the energy-saving effect on applying Trombe wall passive collector design. According to the climatic characteristics of cold region, we analyze the thermal environment regulation strategy, in order to provide a positive significance for the promotion of passive solar energy technology.
