The Response of Human Thermal Perception and Skin Temperature to Step-Changed Activity Level
Diyi Tan, Hong Liu, and Yuxin Wu
Abstract—Considerable researches have been conducted on
human thermal comfort under steady state while studies on
human thermal perception under non-steady-state is not
sufficient. This paper investigates thermal perception of people
who alternated between sedentary exercise and walking on a
treadmill in 20oC and 25oC. Experiments in a well-controlled
climate chamber, including both physiological measurements
and subjective questionnaires, were conducted. The procedure
of the experiments was as follows: subject sat for 30min in
climate chamber to calm down before entered into stage of
activity level step changing, which comprised 30min of walking
at 0.9m/s followed by 30min of sitting and then walking at
1.2m/s followed by 30min of sitting. 20 subjects were involved.
The results indicate that there is poor correlation between
thermal sensation vote and skin temperature in activity level
transient periods, and the PMV is not suitable to predict the
thermal sensation of people occupying dynamic activity when
their thermal sensation does not achieve to steady state.
However, there is approximately linear correlation between
thermal sensation vote and variation rate of temperature with
time in the first few minutes after subjects stopped walking.
