Abstract
The objectives of the paper are to analyze human convection, radiation,
evaporation, respiration, conduction, and diffusion heat losses when the
operative temperature increases from 26-34.4?C and then decreases from
34.4-26?C with a ratio of 1.4?C per 5 minutes. A energy balance model is used
for sedentary subject. The results show that during temperature rising, all
the heat losses are linear functions of temperature, while during temperature
dropping, the convection, diffusion, and respiration heat losses are
quadratic functions of temperature. The results are useful for thermal
comfort evaluation and heating, ventilation, and air conditioning design.
