摘　　要：热环境中人体躯干与头部都是大量出汗的部位,且头部的热感能在很大程度上影响整体的热感,因此通风降温服的设计应兼顾这两大区域进行针对性的降温。为探究热环境中头部联合躯干降温方式的效果,制作了管道通风背心与通风帽,并进行了躯干降温和躯干联合头部降温的对比试验。在温度为30℃、相对湿度为40%的人工气候室内,8位男性受试者完成了2次运动试验,试验中记录受试者的生理响应与主观感觉评价。结果显示:在总通风量恒定(9 L/s)的情况下,躯干与头部联合降温可显著降低额头部位的皮肤温度,对促进头部散热有积极作用;增加头部降温有助于降低受试者运动过程中的热感、湿感与不舒适感,特别是能显著缓解整体热感,但对湿感和不舒适感无统计学上的显著作用。The torso and head are the sweating parts in hot environment,and the thermal sensation of the head has a great impact on overall thermal sensation.Therefore,when designing ventilation cooling garments,both the torso and head must be taken into account.The purpose of this study was to compare the cooling effect of only the torso cooling(V)and the torso plus head cooling(VH)methods in two exercise trials.A pipe ventilation vest and a ventilating cap were made and evaluated on eight male subjects in an artificial climate chamber with a temperature of 30℃and a relative humidity of 40%.The physiological responses of the subjects and the subjective sensation votes were recorded during the whole test.The results show that with the total ventilation constant at 9 L/s,the VH method significantly reduces the skin temperature of the forehead and has a positive effect on promoting heat dissipation in the head.VH method helps reducing the subjects′thermal,wet and discomfort sensation during the exercise.Especially it significantly relieves the overall feeling of heat.However,there is no statistically significant difference in wet and discomfort sensations between V and VH method.
