Study on human thermal comfort under low-pressure environment based on orthogonal test method

Carries out experiment on human thermal comfort under low-pressure environment, which is designed by orthogonal test method and thermal sensation is obtained by questionnaire. Analyses emphetically the significance of air temperature, pressure and air velocity on mean thermal sensation (MTS). The results show that air temperature is the first significant factor affecting MTS and the second is air pressure, and the influence of air velocity is little under low pressure environment of 75.994～101.325 kPa (0.75~1.00 atm).
