The Influence of Sweating on the Heat Transmission Properties of Cold Protective Clothing Studied With a Sweating Thermal Manikin

Meinander H., Hellsten M.

International Journal of Occupational Safety and Ergonomics

2004

Vol. 10, No. 3

263--269

One of the objectives of the European SUBZERO project was to study the influence of sweat evaporation and condensation on the heat transmission properties of cold protective clothing. With the sweating thermal manikin Coppelius, water vapour transfer through and water condensation in the clothing can be determined simultaneously with the thermal insulation. In this study, 4 cold protective ensembles, intended for use temperatures between 0 and -50 °C, were measured with the dry manikin and at 2 different sweating rates. In addition, the ensembles were measured with non-sweating thermal manikins and in wear trials.
