To avoid adverse environmental temperature effects on human body and working capacity, it is possible to manufacture the garments with integrated electrical systems and such components as Peltier elements, able to provide the microclimate regulatory function. Such clothe have to ensure not only effective operation of the system, but also the clothing requirements, such as comfort, light weight, air permeability, etc. 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. For development the system and the clothe it is performed experiments to optimize the product microclimate regulatory function.
