THERMOELECTRIC COOLING SYSTEM USING PELTIER EFFECT

Abstract: The continuous advancement in science and technology has led to the development of various systems capable of producing refrigeration effects. Conventional refrigerators commonly use refrigerants such as Ammonia and R12, which are harmful to the environment. This project proposes the development of compact cooling units designed for applications such as medicine storage in medical shops and hospitals, preservation of food for patients, and use in small pan-shops, hotel rooms, and guest houses. These units utilize thermoelectric modules based on the Peltier effect, thereby eliminating the need for harmful refrigerants and mechanical components like compressors and evaporators. This eco- friendly refrigeration approach not only helps in protecting the ozone layer but also reduces the overall cost of the refrigerator. The system is capable of effectively cooling a storage volume of up to 48 liters.
