Building A Solid-State Refrigerator Using Thermoelectric Cooler

Abstract

The goal of this project is to build solid-state refrigerator that can be imbedded inside vehicle and passenger compartment using Thermoelectric Cooler (TEC). Its main aim is to help people who need cooler for their personal purposes, such as medicine, food and drink. The most important utilization is for the preservation of medicine like insulin that needs to keep temperature under control. A Thermoelectric Module (TEM) is used instead of traditional design that used compressor, so it becomes solid-state as it is based on the principles of Peltier effect. The use of Peltier effect is to create heating and cooling sides, also to maintain effectiveness, where electric power supply is used from waste energy like heat from exhaust or cold water from radiator. The design of the refrigerator is based on heat transfer principle of thermoelectric generator in order to develop the cooling effect, in addition to the heat sink and fins are added to the hot side for cooling down the temperature. The design should be able to keep a suitable temperature (10-14)°C inside the refrigerator, which is suitable for preserving food and medicine. Furthermore, it creates no vibration or noise in the system.
