Description

The sweating thermal manikin COPPELIUS II has been developed by Tampere University of Technology together with Danish PT Teknik. Thermal comfort properties of garments and garment assemblies can be determined by simulating continuous human heat and sweat production (0-300 g/m2h) in different environmental conditions and in different activity levels. It is applicable for protective clothing, outdoor clothing, sportswear, medical garments and smart materials to measure dry and evaporative heat transfer through clothing materials and in regard to garment designs. The values which can be measured or calculated are regional and mean heat supply (W/m2), surface temperature (°C), temperatures at different layers (Pt sensors, °C), total weight increase during the test (g), weight increase of the separate clothing layers (g), thermal resistance or insulation Rct (m2K/W), evaporative heat loss He (W/m2), and water vapor permeability (%).
The sweating thermal cylinder can be used for determining thermal comfort of different material layer combinations and thermoregulation properties of PCM materials.
Environmental conditions can be controlled in the climatic chamber:
• temperature range of the chamber T -50°C…+80°C
• clothing physiology measurements in the range T -50°C…+40°C
• relative humidity above 0°C from 0 to 95% depending on the temperature
• air flow of 0.3…0.5 m/s
