备注

为研究夏季城市居住建筑内人体热调节行为的节能效率,以在校大学生为受试对象,在人工气候室测试了不同温度调节下人体生理和心理测试的变化规律,确定了静风静坐、电风扇、扇扇子、湿毛巾擦拭四种热调节行为方式的热容忍温度,通过动态能耗模拟,计算了不同容忍温度所对应的空调节能潜力.研究发现:人体体温随室内空气温度升高而升高,但升幅不大; 心率和血压值随空气温度升高并无显著性变化; 四种热调节行为的容忍温度范围为:29.2~31.1 ℃,并对其进行了排序; 夏季,热调节行为的容忍温度越高,则空调使用时长越短,节能率越大,四种热调节行为的节能率变化范围为:0~57.2%.
In order to study the energy saving efficiency of human body thermal regulation behavior in urban residential buildings in summer, the college students are subject to the subject, and the changes of human physiology and psychological testing under different temperature regulations are tested. It is determined that the static wind, electric fan, hand fan, wet towel wipes the heat toleration temperature of the four thermal adjustment behavior, and calculates air conditioning energy saving potential corresponding to different tolerance temperatures by dynamic energy consumption. The study found that as room temperature increases, the body temperature increases with the increase in air temperature, but the increase is not large; the heart rate and blood pressure value have no significant change with the increase in air temperature. The tolerance temperature of the four thermal modulation behavior ranges from 29.2 ℃ to 31.1 ℃, and it is sorted. In the summer, the higher the tolerance temperature of the heat regulating behavior, the shorter the air conditioner, the larger the energy saving rate, the energy saving rate variation of the four thermal regulation behavior ranges from 0% to 57.17%.
