ABSTRACT:
This study looks at using the Peltier effect to design and optimize a solar-powered refrigeration system. This study investigates a substitute for traditional compressor-based refrigerators, which use hazardous refrigerants and consume a lot of power, in response to the growing need for sustainable and eco-friendly cooling systems.
Thermoelectric modules, solid-state devices that facilitate heat transmission by applying an electric current, are the system's central component. These modules may produce a temperature differential by utilizing the Peltier effect, which allows for cooling on one side and heat generation on the other. The system is self-sufficient and less dependent on grid electricity thanks to the integration of solar panels, which capture solar energy and power the thermoelectric modules.
The study covers the selection and characterization of appropriate thermoelectric materials as well as the basic concepts of thermoelectricity. A prototype system is carefully planned and built, including the integration of solar panels, the design of a heat sink, and the application of a microcontroller-based control system for maximum efficiency. The purpose of this research is to show that solar-powered thermoelectric refrigeration systems are a practical and environmentally responsible substitute for a range of applications, especially in isolated locations with poor grid energy availability. This technology helps create a more sustainable and energy-independent future by reducing its negative effects on the environment and providing a sustainable cooling solution.
