The effect of thermal resistances on the coefficient of performance of a thermoelectric cooling system

A thermoelectric system of cooling and heat control, which consists of a thermoelectric module, as well as heat supply and removal blocks, is considered. The coefficient of performance of the cooling system with account for thermal resistance of heat supply and removal blocks is calculated based on the mathematical model using the working characteristics of a commercial thermoelectric module as initial data. The dependences of the coefficient of performance on the current are obtained for values of cooling parameters. The optimal values of the thermoelectric module supply current are analyzed.
