Abstract

This research work explores the integration of Peltier module in hybrid source thermal desalination system for efficient surface temperature measurement. The study investigates the performance of Peltier module that can be used to monitor temperature differentials between the evaporation and condensation chambers and surface temperature of the condensation chamber for the developed desalination unit, enhancing the efficiency of desalination process. An analytical model is derived to link the effective temperature difference within the Peltier module to the load current measured by the true rms multimeter. The module parameter is estimated for the intrinsic and extrinsic values of seebeck coefficient and resistance for the loading condition. The study indicates that the slope of change of internal temperature difference with respect to the load current is 0.8 °C/A at the boiling point temperature. The hardware setup is designed and developed to verify the analytical value obtained from the derived analytical expression of parameter of the Peltier module. The hardware results are being analysed and will be presented in the future work.
