The results of measurements and calculations of the energy characteristics (cooling capacity and coefficient of performance) of a thermoelectric refrigerator model in air are presented. Heat flux measurements were made using two heat meters located on opposite sides of the thermoelectric module. Numerical analysis of current, voltage, and temperature measurements allowed us to establish the dependence of the cooling capacity and temperature drop across the thermoelectric module on the temperature of its hot side. Experiments determined the energy characteristics of the cooling process over a wide range of operating parameters. Computational modeling of heat transfer processes in the refrigerator model under various operating conditions was conducted; the modeling results are consistent with the measurement data. Keywords: thermoelectric cooling system, heat flux measurement, least-squares method, computational modeling.
