temperature’ means one side or part of the body feels warmer (or cooler) than the other. The authors [19] also found that nonuniformity of thermal sensation affected thermal comfort and acceptability in non-uniform environment. In the present study, thermal sensation difference between body parts and body sides was combined into a new term ‘thermal sensation change with space’ and inquired by an additional questionnaire in the present experiment. It was found that 97% of the subjects perceived obvious thermal sensation change with space during the non-uniform exposures. Thermal sensation change with space may be the reason for the scattering of the points in Fig. 4.
Considering the strongest feeling in the present study comes from the difference between the coolest and the warmest body part, the maximum thermal sensation difference between body parts was chosen to represent the thermal sensation change with space. Taking the responses obtained when subject’s whole body thermal sensation vote close to neutral (0.2
