AUTOMATIC TEMPERATURE CONTROLLED LOW POWER WATER SUPPLY SYSTEM

Conventional water heaters store hot water in a cylinder or a tank. Hot water geysers are one
of the largest consumers of electrical power in the average domestic household. The project
aims to improve the current designs by using minimum power to heat water without
jeopardizing the flow rate. The main objective of the project is to design a low power water
heater system. The process variable to be controlled is temperature. Flow is another process
variable to be monitored during the process. The project requires knowledge from different
disciplines. The automatic low power domestic water heater requires the knowledge of
thermo fluids, power electronics, and microprocessor programming. The simulation on
LABVIEW is done to generate a trend of the system. A plot of the temperature changes will
ensure that the operation of the sensor is monitored. The results show the open loop system of
the project. The prototype had to be implemented to demonstrate the integration of different
circuit that exist in this system, namely the microcontroller circuit and relay circuit. The
project was a success.
