Anotācija Peltier elements offers new qualities in various cooling applications, but do not compare well with traditional cooling systems due to a low efficiency. This paper claims an approach to increase Peltier element based cooling system efficiency using advanced power management system. It is realized by using Peltier element as Thermo Electro Generator periodically turning excess heat to electricity. This method is effective in several specific applications that suffer from weak heat dissipatoin. Such system was created to expose potential gain for human body microclimate controlling system. Experiments revealed that it is possible to recuperate up to 3% of supplied energy at 3 to 5 °C temperature difference between hot and cold side of Peltier element. Main advantages and drawbacks are presented, including further study opportunities. Research opens new direction for improving cooling ability of Peltier elements, thus bringing it one step closer to efficiency of gas compression based cooling systems.
