拉萨传统民居阳光起居室夏季室内热环境研究

Indoor Thermal Environment of Lhasa Traditional Residential Solar House in Summer

为了解拉萨地区阳光起居室内的夏季热环境及应用现状,通过对拉萨市村镇中民居的空间布局、居民的生活习俗、阳光起居室改造后的生活空间迁移进行调研,并选取一典型户进行了实测。得到以下结论:拉萨村镇传统民居的改造主要围绕太阳能热利用展开,目的是提高室内温度,改善室内热环境;阳光起居室的日照条件和围护结构低蓄热性,恰好可以保证该空间适当的舒适温度,并保证夜间凉爽,有利于睡眠。同时可以提高与阳光起居室相邻房间温度,用于改善其室内热环境;增减衣物和开窗通风是当地居民夏季适应温度变化的主要调节措施;建筑围护结构蓄热性是提高空间夜间热舒适的关键因素。

In order to understand the summer thermal environment and application status in the solar house of Lhasa,the space layout of the residential houses in the villages and towns of Lhasa,the customs of the residents,and the migration of the living space after retrofitting the solar houseare investigated,and a typical household is selected.Actual measurement.The conclusion is as follows:the transformation of traditional houses in Lhasa villages and towns mainly focuses on solar thermal utilization,with the aim of improving indoor temperature andindoor thermal environment;the sunshine conditions of the solar house and the low heat storage of the enclosure structure can just ensure the proper space.Comfortable temperature and cool at night for sleep.Meanwhile,it can improve the temperature of the room adjacent to the solar house,and improve the indoor thermal environment;increasing or decreasing the clothing and window ventilation is the main adjustment measure for the local residents to adapt to the temperature change in summer;the heat storage of building envelope structure isthe key factor of thermal comfortto improve the space at night.
