Regulation of cooling mode of thermoelectric bloc

With the help of a computational model, the cooling modes of a block of a thermoelectric refrigeration unit designed for ship's provision and freezing chambers are studied. The computational model, based on the numerical solution of a system of nonlinear algebraic equations, takes into account the operating characteristics of a serial thermoelectric module and the thermal resistances of heat removal and supply devices. The dependences of the cooling power and the coefficient of performance of the block on the supply current of the thermoelectric modules are calculated. The analysis of the cooling modes of the thermoelectric block is carried out and recommendations for regulating the current strength depending on the current temperature conditions in the provision and freezing chambers are developed.
