Performance Evaluation of Thermoelectric Refrigerator Based on Natural and Forced Mode of Cooling Processes

摘要

The aim of this work is to evaluate the performance of portable thermoelectric refrigerator for vehicles (cars, trucks and buses). Thermoelectric refrigerator is based on the principle of a Peltier effect. TES-12704 thermoelectric module has been used in fabrication and tested. The cooling temperature of fin attached with thermoelectric module inside the refrigerator is measured and compared in natural and forced mode. The thermoelectric refrigerator is advantageous to keep perishable items at low temperature during travelling of the people. The results show that forced mode of producing cooling effect inside the thermoelectric refrigerator gave better performance as compared to natural mode-based thermoelectric refrigerator.
