DESIGN & FABRICATION OF A THERMOELECTRIC REFRIGERATION SYSTEM

Abstract

The Thermoelectric Refrigeration System with Peltier Effect project aims to design and construct a compact and efficient cooling system utilizing the Peltier effect. This solid state Thermoelectric cooling system is designed to maintain a controlled low temperature for various applications. The core components include a Peltier module, a Switched-Mode Power Supply (SMPS) for power regulation, a water cooling block as a heat sink, a pump motor for efficient heat dissipation, and a temperature sensor with a display for real-time monitoring. The Peltier module, functioning as the cooling element, is powered by the SMPS, which provides stable and adjustable DC power. The Peltier module transfers heat from one side to another, achieving cooling on the cold side and heating on the hot side. A water cooling block enhances heat dissipation from the hot side, while a pump motor circulates water to maintain efficient cooling. A temperature sensor positioned strategically measures the system's temperature, and the data is displayed in real time for monitoring and control.
