A high temperature and humidity environment can be easily formed in a confined refuge system, which has a significant effect on the safety of refugees. Human survival experiments in a closed simulation chamber were carried out under high temperature and humidity conditions (the temperature was above 27 °C and the relative humidity was above 70%). The asymmetrical five-grade scale method was used first, and human comfort voting data were collected from 35 groups under different temperature and humidity conditions. A non-linear trend of the effects of different temperature and humidity conditions on human comfort was obtained through analysis, and the boundary curves for different human comfort conditions in a closed refuge chamber were determined. At the same time, a function prediction model of the apparent temperature was established, which had instructive meaning for the study and design of the environment controls and life support system in a closed rescue space for different fields.
