徽州传统民居冬季室内热环境改善研究

Research on Indoor Thermal Environment Improvement of Huizhou Traditional Dwellings

对徽州传统民居的天井、围护结构提出了改造方案,并用TRNSYS软件对改造后民居的冬季室内热环境进行模拟分析,发现仅增加围护结构的保温性能,室内热环境并未得到明显改善;在此基础上提高天井的气密性,冬季室内平均气温比原来提高了3.0~4.0℃,且冬季舒适时间占比最高达到了33%,室内热环境改善效果明显。

In order to improve the indoor thermal environment in Huizhou traditional dwellings, a patio and building envelope retrofit scheme is proposed, and the indoor thermal environment in winter is simulated by TRNSYS. It is found that the indoor thermal environment is slightly improved if only the insulating performance of building envelope is strengthened. However, indoor temperature can be increased by 3.0-4.0 ℃ compared to that of the original building. In addition, the probability of indoor temperature at comfortable zone is achieved over 33%,therefore, the improvement of indoor thermal environment is obviously based on the proposed building envelope retrofit scheme.
