In this study, performance values of thermoelectric modules of two cases, two identical two-stage connected thermoelectric modules and one same module alone, were compared. In both case, working temperature differences and acquired heat of the modules were taken the same. While the temperature differences were changed from 10 degrees C to 65 degrees C, for single module, cooling power at optimum efficiency points for every single temperature differences were registered. In the same temperature span, optimum efficiency working point for two-stage working module was determined while the temperature values at the connected point were changed. In the study, the sed thermo element was CP 1.4-127-10 produced by Melcor. The experiments has shown that for single module, the highest efficiencies were at temperature differences up to 56 degrees C and for two-stage connection module, the temperature differences higher than 56 degrees C were shown the highest erformance.
