Fabrication of Thermo Electric Module for Cooling and Heating Applications Using Solar Energy

Thermo-Electric refrigeration is one of the recent developments in the field of refrigeration. The development of semiconductor technology enhanced the feasibility of Thermo-Electric applications to greater extent. Thermo-Electric refrigeration systems were worked based on the principle of Peltier effect, where the passage of direct electric current through the junction of two dissimilar semiconductor materials causes the junction to either cool down (absorbing heat) or warm up (rejecting heat) depending on direction of current. In the process of Thermo-Electric refrigeration the cooling effect was effectively utilized but heat energy developed by module is dissipated to environment. Now a days energy conservation plays a major role in day to day life due to energy crisis. Hence a solution has to be given to utilize the heat energy dissipated to environment for the useful heating applications and conserve waste heat energy. A novel idea of this is to utilize both heating and cooling effects generated by Thermo-Electric module. Cooling effect can be used for storage purpose and the waste heat energy for heat storage and used as hot pack. The power is given by both house hold supply and by solar energy for Thermo-Electric system for heating and cooling applications.
