Analyzing of Thermoelectric Refrigerator Performance

Year: 2011

Type: conference-paper

Abstract: The refrigeration system of thermoelectric refrigerator (TER; 25 × 25 × 35 cm3) was fabricated by using a thermoelectric cooler (TEC; 4 × 4 cm2) and applied electrical power of 40 W. The TER has not cooling fan for the coldness circulates in the refrigerator. The temperature of TER was measured at ten points to check the cooling system. The current, differential temperature, time, and coefficient of performance (COP) were analyzed. TEC cold plate temperature (Tc) was decreased from 30 °C to -4.2 °C for 1 hr and continuously decreasing to -7.4 °C for 24 hrs and 50 °C for hot plate temperature (Th). The TER temperature was decreased from 30 °C to 20 °C in 1 hr and slowly decreasing temperature for 24 hrs. The maximum COP of TEC and TER were 3.0 and 0.65, respectively.
