The effects of vertical temperature differences (VTD) on human thermal comfort have attracted growing attention from researchers when utilizing split air conditioners for winter heating. This study underscores the need to investigate the influences of gender disparities in the context of significant vertical temperature variations, a critical aspect that has not yet been comprehensively explored. Twenty gender-balanced subjects were exposed to a variety of stratified thermal environments created by a split air-conditioner. Their overall and local perceptual and physiological responses were measured at various operative temperatures and VTD. Results show that females have lower thermal sensation vote (TSV) and mean skin temperature under the same environments compared to males. Neutral operative temperatures of females and males are 23.7 ˚C and 20.8 ˚C, respectively. On the cold side, lower leg and foot thermal sensations are dominant whereas chest and back are dominant on the warm side. When females rated “slightly warm” (TSV equaled 1) or “warm” (TSV equaled 2), or males rated “slightly cool” (TSV equaled −1), increased VTD can lower thermal acceptability. The research findings have significant implications for the understanding of gender requirements of stratified heating environments and for maximizing the thermal comfort of the two genders.

垂直气温差异下热响应的性别差异

在利用分体式空调进行冬季供暖时,垂直温差(VTD)对人体热舒适度的影响越来越受到研究人员的关注。这项研究强调有必要在显着的垂直温度变化的背景下调查性别差异的影响,这是一个尚未得到全面探索的关键方面。二十名性别平衡的受试者暴露在由分体式空调创造的各种分层热环境中。在不同的工作温度和 VTD 下测量了他们的整体和局部感知和生理反应。结果显示,在相同环境下,与男性相比,女性的热感觉投票(TSV)和平均皮肤温度较低。女性和男性的中性工作温度分别为 23.7 ℃ 和 20.8 ℃。在寒冷的一侧,小腿和脚部的热感觉占主导地位,而在温暖的一侧,胸部和背部的感觉占主导地位。当女性被评为“稍热”(TSV 等于 1)或“温暖”(TSV 等于 2)或男性被评为“稍冷”(TSV 等于 -1)时,增加的 VTD 会降低热可接受性。研究结果对于理解分层供暖环境的性别要求以及最大限度地提高两种性别的热舒适度具有重要意义。
