    摘要:

    为了探究辐射供冷环境下人体姿态对热舒适的影响,本文采用主观调查问卷与生理指标测试的方法对夏季顶板辐射供冷下坐姿人体和卧姿人体的热舒适性进行了实验研究。结果表明:人体卧姿状态与坐姿状态皮肤温度的分布有一定差异,两种姿态下热感觉在-0.5—0.5范围内时,卧姿人体所需要的操作温度比坐姿人体高0.5℃左右;最佳热舒适点的操作温度,卧姿状态比坐姿状态高0.7℃。

    Abstract:

    In order to explore the effect of human posture on thermal comfort under radiation cooling environment, the thermal comfort of sitting and lying posture under radiation cooling was studied experimentally by using subjective questionnaire and physiological index test in summer. The results show that the skin temperature distribution in the lying posture is different from the sitting posture, the operating temperature of the lying supine human is about 0.5 ℃ higher than the sitting posture when the thermal sensation is within the range of -0.5-0.5, and the operating temperature at the optimum thermal comfort point is 0.7℃ higher in the lying posture than that in the sitting posture.
