A prototype of Thermoelectric Cooling system integrated with portable refrigeration unit using Peltier for space cooling act as a heat pump has been introduced in this work. In today’s scenario, due to the development of production, the home appliances such as refrigerator is the most energy consuming and disposal of refrigerants. It is consequently release a lot of unneeded gas all over the world that contributing the factor of global warming on climate change. Additional, the normal refrigeration, Vapor Compression Refrigerator system use high power consumption than this development of thermoelectric refrigerator. A simplified analytical model for the thermoelectric modules (TEC12706, TEC12710 and TEC12715) were adopted to investigate the efficiency of this thermoelectric refrigeration which is based on the parameter of the result taken and evaluation on performance of thermoelectric refrigeration. The experimental test in a reduced-scale polystyrene ice box, 5 liters has concluded that Peltier TEC-12706 could work more efficient than the other Peltier modules and had achieved temperature at 130C in one-hour duration and realized an average energy usage this system only uses about 3.9231 kWh/month for three hours’ battery lifespan before recharged. The retrofit also yielded excellent performance and temperature stability from the TEC units with the optimum COP value at 0.5. Plus, this experiment was improved by Arduino UNO microcontroller to ensure the system of this thermoelectric refrigeration system cut off automatically when the Arduino detected the gradient of temperature for power save. This thermoelectric system can continuously improve the previous research to ensure the thermoelectric refrigeration can continually develop in market value.
