摘要
以湘西传统民居的典型代表"吞口屋"为研究对象,通过对其进行夏季和冬季典型日室内热环境实测及评价,得出了湘西传统民居PMV拟合曲线和可接受温度,分析了湘西传统民居的室内热环境状况,在此基础上探讨被动式节能改造措施在湘西传统民居中的应用,从建筑朝向优化、窗墙比优化、提高围护结构保温隔热性能、强化自然通风等方面提出被动式节能改造策略,并模拟改造策略对热舒适度的影响,对湘西传统民居改造提出了具有针对性的方案和建议。
An analysis was carried out on the thermal environment of a traditional dwelling in Western Hunan by field study and indoor thermal evaluation on the typical summer and winter day. Based on the results,this paper calculated the PMV fitting curve and acceptable temperature of the traditional dwelling and explored the feasibility of some passive energy-saving retrofitting strategies,such as the optimization of building orientation and windowwall ratio,the retrofitting of heat insulation properties of building envelopes and reinforcing natural ventilation.Moreover,the impact of the retrofitting strategies on the thermal comfort was simulated. Finally,specific schemes and suggestions were put forward for the energy-saving retrofitting of the existing vernacular dwellings in the rural area of Western Hunan.
