摘要
大量的应用及研究表明,夏季气温过热是制约被动式太阳能采暖技术应用的关键因素之一。本文通过对大连理工大学校园内的太阳能空气集热模块实验设施的夏季降温实验,在分析大连地区的夏季自然降温潜力的基础上,重点讨论夜间通风与室内热质结合、集热模块的遮阳与通风方式等对缓解夏季过热程度的作用。实验结果表明,集热模块的通风与遮阳能有效降低南墙壁面温度,夜间通风与热质结合时能降低室内温度1～2℃。
The applications and studies have shown that overheating in summer is one of the key issues which restrict the application of passive solar heating technology. The paper, which introduces the summer cooling experiment of the passive solar building coupled with solar air collector module （ built in Dalian University of Technology campus ）, based on the analysis of natural cooling potential in summer of Dalian, emphasizes on the effect of night ventilation combined with thermal mass, ventilation of, etc. The results show that sunshade and ventilation of the collector module have good effect on the south wall temperature, thermal mass of the roof can delay and decrease outdoor temperature wave, night ventilation combined with thermal mass can reduce the indoor temperature of 1-2℃.
