The existence of combined effect caused by temperature and
relative humidity on physiological parameters was proven, and it
was necessary to quantify it. To simplify the quantifying process, a
quiet or light work (65 W/m2 below) with ordinary clothing
(0.5 w 1.2 clo) is always adopted as a basic condition [16], and the
other conditions are adopted as the comparison conditions. In this
paper, the change values of physiological parameters are used to
represent the effects caused by environment factors.
