摘要:为探索一种在低温环境中改善人体舒适性的局部供暖方式,于 2011 年 1 月在自然通风环境的实验室进行
实验,共有 62 名受试者。设有 3 个实验工况,分别对受试者的颈部、腹部和小腿进行局部供暖风,实验持续 30 min,
受试者按照其主观感受填写调查问卷,包括人体热感觉、湿感觉、气流感、热环境可接受度等。研究结果表明:
对局部供暖风可以改善人体的热感觉,但暖风带来的干燥感和过大的气流感可能引起人体对热环境不满意,并且
还可能出现头晕恶心等不良反应,其中,对颈部和腹部送风会产生明显的不舒适感;而对小腿送风的负面影响小,
可以作为一种改善人体舒适性的局部供暖方式。

Abstract: In order to explore a local heating way that can improve fort in the cold environment, the
experiment was carried out in a natural ventilation environment in January 2011 with 62 subjects. The experiment has 3
setting conditions, . locally applying the warm airflow to the subjects’ neck, waist and calf respectively. Subjective
questions including thermal sensation, humidity sensation, air movement sensation and thermal acceptability were
