Abstract
ABSTRACT This paper focuses on two different methods of obtaining performance parameters of a thermoelectric cooler. Based on the simulation results using COMSOL Multiphysics the performance parameters, such as maximum cooling capacity, maximum current and voltage for various temperatures on the hot side of module and coefficient of performance (COP) for various temperature differences across the module, are obtained. The system has been simulated for temperature of the hot side ranging from 303.15 K to 333.15 K with an interval of 5 K. Coefficient of performance is obtained for a temperature difference of 20 K, 40 K and 60 K across the module for every value of temperature condition on the hot side of module. The system is also modelled numerically and the results obtained are compared with the simulated results. The variation of resistivity, seebeck coefficient and thermal conductivity of Peltier elements with temperature variations are considered for numerical modelling.
