Thermoregulation of Smart Clothing based on Peltier Elements

The paper proposes a method of clothing creation that provides cooling (or heating) of the body based on a system of series-connected Peltier elements. The calculation of the power of heat loss for cooling the body as applied to smart clothing for the upper body, as well as the calculation of the power for cooling produced by the system of series-connected Peltier elements, is presented. It is shown that this design provides the designed cooling of the upper body by 5 K. Experimental studies of a system of series-connected Peltier elements were carried out and the effect of cooling one side of the surface to the required temperature was revealed.. Smart fabric is modeled as a flexible, inextensible multilayer shell. The dependence of the heat loss on cooling the body from the power generated by Peltier elements is nonlinear due to the fact that part of the electric current energy is spent on the thermal resistance of the electric circuit itself, which complicates the application of the proposed approach, but does not exclude the possibility of minimizing this effect in the future.
