Title Heat gain from thermal radiation through protective clothing with different insulation, reflectivity and vapour permeability
Bibliographic information 2010, Vol.16, No.2, p.231-244. Illus. 40 ref.
Abstract The heat transferred through protective clothing under long wave radiation compared to a reference condition without radiant stress was determined in thermal manikin experiments. The influence of clothing insulation and reflectivity, and the interaction with wind and wet underclothing were considered. Garments with various outer materials and colours and additionally an aluminised reflective suit were combined with dry and pre-wetted underwear layers. Under radiant stress, whole body heat loss decreased, in other words heat gain occurred compared to the reference. This heat gain increased with radiation intensity and decreased with air velocity and clothing insulation. Except for the reflective outer layer that showed only minimal heat gain over the whole range of radiation intensities, the influence of the outer garments, material and colour was small with dry clothing. Wetting the underclothing for simulating sweat accumulation, however, caused differing effects with higher heat gain in less permeable garments.
