This work deals with experimental investigations on human reaction to local air movements of people in global thermal comfort, performing light activity. An analysis on draught risk was developed comparing the results with previous research findings on human response to draught. The intensity of air velocity, in terms of mean value and relative turbulence, was referred to the level at which normally clothed people could perceive and feel air movements behind the neck, in global neutral thermal condition. This work provides evidence of how the exposure duration to air movements plays a fundamental role on air flow sensitivity. The human reaction to an air flow was observed to vary with exposure duration: the feeling changes in intensity while the air flow persists blowing constantly. Moreover, different reactions have been observed between female and male test persons. Although these results were observed in the typical situation of horizontal air jet flows blowing from behind, they could apply in climatically controlled environments, where air flow is supplied horizontally at low speed, and the occupants are sitting far from the inlet section.
这项工作涉及对处于全球热舒适状态且进行轻度活动的人员对局部空气流动的人体反应进行实验研究。通过将结果与先前关于人体对气流反应的研究结果进行比较，开展了一项气流风险分析。空气流速的强度，以平均值和相对湍流来衡量，是指在全球中性热条件下，正常着装的人能够感知并感觉到颈部后方空气流动的水平。这项工作提供了证据，表明空气流动的暴露持续时间对气流敏感性起着根本性作用。观察到人体对气流的反应会随着暴露持续时间而变化：当气流持续不断吹拂时，感觉的强度会发生变化。此外，在女性和男性测试对象之间观察到了不同的反应。尽管这些结果是在从后方吹来的水平空气射流的典型情况下观察到的，但它们可应用于气候控制环境中，在这种环境中，空气以低速水平供应，且居住者坐在远离入口区域的地方。
