The research is dedicated to microclimate regulatory vest with an integrated electrical system, which is also composed Peltier elements, and cooling function is based on the heat conductivity in solids [5]. In the experiments with thermoelectric modules - Peltier elements - and the different thickness of copper, bronze and steel threads and different density fabrics, as well as copper foil, it is observed that the copper foil provides the necessary heat removal, which, in turn, provides favorable conditions for the cooling. To verify microclimate regulatory vests compliance with the general requirements of article, it is scheduled an assessment at physiologically - hygienic point of wearing by the appropriate operating conditions.
