Abstract:
This research presents the empirical results of the optimized heat transfer that made the peltier plate generated the maximum electricity output. For the heating system, the electricity supplied to the heating coil via the solid-state relays and the feedback signals were sent by the thermocouples.
The control system used LabVIEW with PID Control Toolset and the USB-6008 interface in order to communicate between computers and heat transfer process for the peltier plate at the heat junction. The heat sink was used for cooling the peltier on the cold junction for the better electric output.
The results show that the heat input at 68 degree Celsius, which was controlled by PID controllers using Ziegler-Nichols method, providing the best Seebeck coefficient. The module with dual-diagonal arrangement type delivered the best outputs which are 4.612 Volts and 4.658 Volts at 120 degree Celsius . On the other hand, the dual-parallel modules gave the worst results which are 4.308 Volts and 4.378 Volts at 120 degree Celsius.
