Thermal comfort is an important aspect of the human health. When exposed to weightlessness, thermal comfort of the human body will be different from that in terrestrial condition, due to physiological changes induced by weightlessness. In order to study the human thermal comfort under weightless environment, a 3-stage experiment was conducted. In the first stage, 6 male subjects were exposed to 84 environmental conditions that were combined by 7 kinds of air temperature, 4 kinds of relative humidity and 3 kinds of air speed. During this stage t...
