摘要

In this study, the design and implementation of a new portable thermoelectric generator of 100 W for low geothermal temperatures has been carried out. For this system, a new SCADA-based testing and measuring system equipped with special software has been developed and employed for the first time. Thus, effects of the hot??cold water flow rates, the temperature differences between the surfaces and the load resistance affecting output power and efficiency of the thermoelectric generator have been investigated by a single testing and measuring system device. In the established SCADA-based testing and measuring system, the hot-cold water flows passed throughout the surfaces of the thermoelectric generator were increased by up to 3.7 and 12.8 l/min, respectively. Then, the temperature difference between the surfaces of the thermoelectric generator was measured as 67 0;C. When the load resistance of the thermoelectric generator was about 15 :9;, the maximum power of the thermoelectric generator was obtained as 41.6 W and the conversion efficiency was calculated as 3.9%. Also, the SCADAbased testing and measuring system will open up a new stage in examination of various thermoelectric generators.
