热环境下人体穿着热湿舒适性研究

Study on Thermohumid Comfort of Human Dressing under Heat Environment

研究不同环境温度和环境湿度条件下,人体穿着不同服装时出汗量、皮肤温度、衣内温湿度、主观感觉等人体生理指标的变化。结果表明:①环境温度和环境相对湿度变化,所测得的各生理指标都发生显著变化,表明环境因素对人体热湿舒适性有很大影响;②热环境下具有良好的透湿透气性能的现行制式陆军夏服表现出良好的热湿舒适性能,而纯棉服装的热湿舒适性较差,尤其是在高温高湿条件下穿着时。因此对于夏季服装,透湿透气性好的服装穿着最为舒适。

The changes of human physiological indexes such as sweating amounts, skin temperature, microclimate temperature and relative humidity, human sensory are studied under different environment conditions. The test results show:(1)The human physiological indexes are changed significantly with the change of environment temperature and relative humidity. The human thermohumid comfort is greatly affected by the environment factors. (2) The hot+humid comfort of the military summer uniform is better than other clothing under heat environment. But the cotton clothing is worse especially under high temperature and high relative humidity conditions. So it is better to wear the clothing with good permeability in summer.
