北京高校宿舍供暖前后室内热环境变化及其对学生睡眠热舒适的影响
摘要：为探究供暖前后宿舍内热环境差异及其对学生睡眠热舒适的影响，在北京某高校实地调研了8个不同朝向宿舍的室内热环境，并采用问卷调研和睡眠手环监测结合的方式获得了16名高校学生的睡眠质量情况。结果表明：供暖前宿舍内夜间平均温度为(18.6±1.1)℃,供暖初期为(20.2±1.4)℃,满足标准要求；实测期间宿舍夜间相对湿度高于30%,满足舒适度要求；床褥系统总热阻约为3.5～4.9 clo,其中，睡衣热阻大约为0.03～0.40 clo;供暖初期受试者睡前热中性温度为18.0℃,可接受温度范围为16.0～19.8℃,早晨醒后倾向更暖的环境；睡前热感觉与睡眠质量存在显著关联，当受试者睡前热感觉偏暖时，睡眠满意度及深睡眠比例较高，有利于睡眠。

Changes in indoor thermal environment before and after heating in some dormitories of a university in Beijing and their effect on students' thermal comfort during sleep
Abstract: In order to explore the differences in the thermal environment of the dormitories before and after heating and their impact on the students' thermal comfort during sleep, 8 dormitories with different orientations are investigated in a university in Beijing, and the sleep quality of 16 students is obtained by combining questionnaire survey and sleep bracelet monitoring. The results show that the average indoor temperature in the dormitories during the night is(18.6±1.1) ℃ before heating and(20.2±1.4) ℃ at the initial stage of heating, which meets the standard requirements. During the measurement period, the relative humidity of the dormitories at night is higher than 30%, which meets the comfort requirements. The total thermal resistance of the bedding system is about 3.5 to 4.9 clo, of which the thermal resistance of pajamas is about 0.03 to 0.40 clo. At the initial stage of heating, the thermoneutral temperature before bedtime is 18.0 ℃, and the acceptable temperature range is 16.0 to 19.8 ℃. When waking up in the morning, the subjects prefer warmer conditions. There is a significant correlation between the thermal sensation before bedtime and the sleep quality, and when the subjects feel warm before bedtime, the sleep satisfaction is better and the proportion of deep sleep is higher, which is more conducive to sleep.
