桂北山区乡村民居热环境实测与分析

为研究桂北山区乡村民居热环境现状,选取当地具有代表性的旧民居和新民居,分别测试其在夏季和冬季的热环境参数。测试结果表明:桂北山区气候条件独特,夏季湿热、冬季湿冷;同一季节,新旧民居的室内热环境并没有显著差异;夏、冬季测试期间,新旧民居在大部分时间段均处于Ⅲ级热湿环境标准,但整体而言,民居的夏季热湿环境要优于冬季。针对该地区民居构造特征,在改善民居室内热环境时需充分考虑地域气候特征,将加强围护结构热工性能、自然通风、遮阳隔热、集热蓄热等措施相结合。研究成果可以为山区乡村民居热环境研究提供参考。

Measurement and Analysis of Thermal Environment of the Rural Houses in Mountainous Areas of Northern Guangxi

In order to study the thermal environment of rural houses in mountainous areas of northern Guangxi, thermal environment parameters were conducted in summer and winter, taking the representative old and new houses as examples. The results as follows. The climate in the mountainous area of northern Guangxi is unique, and it''s humid in summer and humid in winter in mountainous areas of Northern Guangxi. In the same season, there is no significant difference in indoor thermal environment between old and new houses. During the summer and winter testing, the old and new houses are in Level-III environment standards for most of the time. On the whole, the indoor thermal and humid environment of summer houses is better than that of winter houses. In view of the structural characteristics of the rural houses in mountainous areas of northern Guangxi, the regional climate characteristics should be fully taken into account when improving the indoor thermal environment of the rural houses. The measures of strengthening thermal performance of enclosure structure, natural ventilation, sun-shading and heat insulation and heat collection and storage should be combined. It can serve as useful references for the study of thermal environment of rural houses in mountainous areas.
