抄録

The clothing microclimate, i.e., the climate within the narrow space between a human body and the clothes, was investigated being focused on the thickness effect of the space for the case where the internal air was ventilated only through the openings of the clothes. A manikin dressed in a shirt made of a material impermeable to the air was used in the experiment and the air flow in the clothing space was detected by an oxygen trace gas technique. The ventilation behavior was simulated by a two-dimensional simplified model and analyzed by a finite difference method. For case in which ventilation was done solely by diffusion, the calculated results agreed well with the experimental ones. If accompanied by convection, the ventilation got greater efficiency depending strongly on the flow rate. Increasing the thickness of the air layer varied the clothing microclimate significantly when it was under about 1cm, but hardly did when above it.
