Description
The problem of energy self-sufficiency rate decreases have occurred because in Japan that rely most of the energy consumed in imports from overseas. So the use of the unused energy to increase the energy self-sufficiency rate is noted now. Heat exhaust that is included in the unused energy is generated in various places of personal belongings such as cars and factories, air-conditioning. There is a thermoelectric generation using the thermoelectric generator that generates power by utilizing a temperature difference in the method for utilization of heat exhaust. In thermoelectric generation system, it is necessary to be circulated by pump a large amount of water to generate temperature difference required for generation. However, circulating by pump consumes a large amount of power. Therefore, in this study, in order to reduce the cooling power and cooling water consumed in the thermoelectric generation system, we subjected two studies on the cooling system method of operation of a thermoelectric generation module to be used for power generation. The first is a "Combined operation" by the combination of the two method “Intermittent operation" and “Adjustment of voltage operation of the cooling system in the thermoelectric generating system. The second is improvement of cooling performance due to the use of tank in cooling system of thermoelectric generation system.
