摘要：
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. Copyright No content may be reproduced or abridged without authorization.
