Abstract

The effect of different sources of radiation on the transmissive and reflective performance of glass was investigated to enable the accurate evaluation of solar radiation through a glass window. The performance of these two properties is quite different with different radiation sources, such as solar radiation from the sun or infrared solar lamps, because of the spectral properties of both the glass and radiation sources. We also discuss how differences in the transmissive and reflective performance of the glass affect the thermal comfort of car occupants. A numerical simulation method, based on comprehensive combined analysis of a thermoregulation model of the human body, radiation models, including thermal radiation and solar radiation, and computational fluid dynamics (CFD) is conducted for this purpose. In addition, the numerical simulation method was combined with a numerical thermal manikin model, including the algorithm for the control system of the thermal manikin, and tested for its effectiveness for the evaluation of thermal comfort. It was shown that the numerical model performed equally well and therefore could be used as a substitute for the thermal manikin for the assessment of equivalent temperature in the experiments discussed in ISO/NP-14505.
