Since prehistoric times people have looked for ways to help with clothing to protect themselves from too low or too high ambient temperature influence. Today thermoregulation by clothing is explored in a special outfit incorporating cooling fluid flow systems, both using high-tech way-made heat-regulating material, and integrated in the garment Thermostatic electrical/electronic systems, such as systems with Peltier elements, where the drive units current that can be achieved temperature changes on it. The world has already discovered and patented smart clothes and other articles, with integrated thermoelectric converters. Here should be mentioned articles with several thermoelectric modules; with integrated heat exchanger with piping system; with air conditioners. Systems differ in terms of power source selection of the operation; both of the solution the heat removal from Thermoelectrical module cold side, but also of the cooling type the warm side, respectively, including: integration in the garment and the maintaining of functional requirements. The following products are presented both advantages and disadvantages of the integration to wear appropriate products, such as additional weight of clothes, a limited vapor and air permeability, a lot of different components, which may cause structural instability and complexity by integration in the smart clothes.
