Abstract

Power and Efficiency Calculation in a Thermoelectric GeneratorThis paper documents a laboratory experiment to determine the efficiency of a commercialthermoelectric generator. Thermoelectric devices make use of the Seebeck effect to convert adifference in temperature to electricity. Thermoelectric devices are used or proposed for a number ofdifferent current applications including waste heat recovery. In the experiment, a LabVIEW dataacquisition system measures real-time efficiency of the thermoelectric device under different loadingconditions. The experiment is well-suited for an undergraduate thermal sciences lab or a demonstrationfor a thermodynamics lecture course. The experiment is also relatively low-cost aside from the dataacquisition system. Results from the system as well as a detailed setup are presented.
