摘　　要：以北京地区某高校的一栋教学楼为研究对象,在供暖季调查了该教学楼自习教室的使用情况。测试了不同使用率下自习教室的室内干球温度、平均辐射温度、相对湿度、风速、二氧化碳浓度等环境参数。并针对自习学生开展了问卷调查,对教室热环境进行了主观评价。结果显示:自习教室的使用率具有明显的规律性;教室内人员密度的增大并未造成热环境的恶化。高校在满足学生对自习环境需求的基础上,若对教学楼自习教室的开放时间、开放数量进行有针对性的安排,将能够产生可观的节能效果。Taking a university teaching building in Beijing as an example, investigates the usage condition of the self-learning classrooms during heating season. Measures the environment variables of the self-learning classrooms under different usage rate conditions, including indoor dry bulb temperature, mean radiant temperature, relative humidity, air velocity and concentration of carbon dioxide. Conducts subjective surveys using questiOnnaires. The results show that there is obvious feature for the usage rate of self-learning classrooms, and there is no obvious worsening tendencY of thermal environment when the occupant density in self-learning classrooms increases. It is practicable to reasonably arrange the number of opened self-learning classrooms and open time according to students＇ demand for indoor environment, which may contribute to significantly reduce the energy consumption of university teaching buildings.
