西北居住建筑分时分区热环境设计参数研究

Study on temporal-spatial partitioned indoor design parameters of residential buildings in Northwest China

根据室内人员活动轨迹和差异化热需求开展分时分区热环境调节是降低供暖空调能耗的有效手段。从人员活动轨迹和热环境行为调节入手,基于主要功能房间部分时段、部分空间供暖模式提出了全空间—工位空间—人体周围微空间的热环境调控范围依次递进的分时分区热环境调节理念。基于现场调研数据归纳出当地居民典型作息规律及不同时段不同功能空间的差异化热需求,结合热舒适理论分析和实验研究,给出了西北地区分时分区热环境推荐设计参数。

Indoor thermal environment regulated partially in time and spatial dimension according to personnel activity trajectory and differentiated thermal demand is an effective way to reduce the energy consumption of heating and air conditioning systems.In light of the activity trajectory and the thermal environment behavior regulation,based on the part-time and part-space heating mode of a main function room,proposes the temporal-spatial partitioned thermal regulation concept-which focuses on the thermal regulation scope from whole space to task space and then the micro-space around human body.Based on the field investigation data,summarizes the typical living schedule of local residents and the differentiated thermal demand of different functional spaces at different times.Combining the theoretical analysis and experimental research on thermal com fort,gives the recommended indoor design parameters of temporalspatial partitioned thermal environment of residential buildings in Northwest China.
