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 oC/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.
