To solve the problem of condensation on the metal roofs of station platforms, it is necessary to estimate the surface temperature of the metal roofs and predict condensation. Therefore, we compared the measured surface temperatures obtained from experiments using flat plates with the estimated surface temperatures calculated from ambient weather conditions to confirm the validity of the estimated values. In the folded-plate experiment, the relationship between the surface temperature and the occurrence of condensation and frost on the upper and lower portions of the square chevron-shaped cross section was clarified by determining the water vapor partial pressure.
