DEVELOPMENT OF FISH COLD STORAGE USING THERMOELECTRIC TECHNOLOGY

Abstract

This project is to apply the principle of thermoelectric technology and design a versatile and portable fish cold storage. The mechanism used for this cooling is the Peltier Effect Device whereby a normal refrigerant for example gases or water as the thermal media is not used in the design. Peltier Effect Device are made of N and P type semiconductors that are joined together by metal contact to form a junction that can perform cooling on one side while heating on the other side. The Peltier Effect Device at the cold part of compartment is put on a heat sink to dissipate the heat transfer by the Peltier Effect Device. Between the Peltier Device and heat sink, thermal paste is applied evenly to help removing the heat faster. Then, a 12V fan is placed below the heat sink. This project is used to detect current temperature using sensor LM35 and variable resistor to adjust the set of temperature.
