EFFECTS OF TRANSIENT TEMPERATURE ON HUMAN'S HEAT LOSSES

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.
