夏季室内热环境与分区控温床垫的被褥气候匹配舒适域

The Indoor Thermal Environment Matches with the Bedding Climate of the Partition Control Hotbed in Summer

通过设计一款能够进行3个分区独立控温的床垫探究在夏季室内24℃、26℃和28℃的热环境下人体局部和整体的热感觉关系以及与被褥气候的匹配舒适域。局部平均皮肤温度与局部热感觉呈现较好的线性关系且腿足部热感觉随其皮肤温度变化最敏感。头部其次,腰背部最后。头部的最佳舒适室内操温度为24.6~27.6℃,热中性温度为26.1℃;腰背部最佳舒适的人-床界面温度为33.0~34.8℃,热中性温度为33.9℃;腿足部最佳舒适的人-床界面温度为32.1~33.0℃,热中性温度为32.6℃。平均心率的数据变化的趋势随着整体热舒适性数据进行变化,当全身热感觉投票均增大时,心率也会逐渐升高。

The local and overall thermal sensation relationship of the human body under the indoor temperature of 24 ℃、26 ℃ and 28 ℃ in summer and the comfort zone matching with the bedding climate were explored through a specially designed mattress with three temperature independently controlled zones. There was a good linear relationship between local average skin temperature and local thermal sensation. The leg and foot thermal sensation were the most sensitive to the change of skin temperature, followed by head and lower back. The best comfortable indoor operating temperature for head is 24.6 ~27.6 ℃,thermal neutral temperature is 26.1 ℃. The optimum human-bed interface temperature for waist and back is 33.0 ~ 34.8 ℃,and the thermal-neutral temperature is 33.9 ℃. The best comfortable human-bed interface temperature for legs and feet is 32.1 ~ 33.0 ℃,and the thermal-neutral temperature is32.6 ℃. The variation trend of the average heart rate data changes along with the overall thermal comfort data,where the heart rate gradually increases with the increase of overall thermal sensation.
