Thirty male subjects participated in four experiments under showers to explore the sensitivities to water temperature and to its slow or rapid fluctuations. After having set the water temperature, at constant flow rate, at either a thermoneutral or a preferred level, subjects were asked to detect thermal changes or to report their thermosensory and affective judgments associated with water temperature changes. Results of water temperature, skin temperature, and subjective estimates showed that skin temperature for thermally neutral sensation under a shower were very similar to those observed in air, and such a thermoneutral level produced no discomfort. Preferred water temperature was slightly warmer and led to slightly elevated skin temperatures, warmth, and pleasantness estimates. Skin sensitivity to water thermal changes was very acute during slow and even more acute during rapid thermal transients. The conclusions of the present study are of value in the production of appropriate equipment to provide thermal comfort to people taking showers.
30名男性受试者在淋浴环境下参与了四项实验,以探究他们对水温及其缓慢或快速波动的敏感度。在将水流速率恒定的水温设定为热中性水平或偏好水平后,要求受试者检测热变化,或报告与水温变化相关的热感觉和情感判断。水温、皮肤温度和主观估计结果表明,淋浴时热中性感觉下的皮肤温度与在空气中观察到的非常相似,且这种热中性水平不会产生不适感。偏好的水温略高,会导致皮肤温度、温暖感和愉悦感估计值略有升高。在缓慢的热变化过程中,皮肤对水热变化的敏感度非常敏锐,在快速热瞬变过程中则更为敏锐。本研究的结论对于生产合适的设备以为淋浴者提供热舒适具有重要价值。
