N2 - In this work, a novel technique to improve the performance of Peltier cooler under varying electric pulse conditions has been studied with the use of phase change material (PCM). The 2D heat transfer model of Peltier cooler along with heat sink has been developed and studied numerically. The results show that the cold side temperature of Peltier cooler with PCM has been reduced significantly from −14.5 °C to −17.5 °C under pulse operation as compared to the Peltier cooler without PCM under pulse operation. It is also found that, there is no significant reduction in COP of the Peltier cooler under pulse operation with PCM as compared to pulse operation without PCM. These studies have been carried out by varying the hot side heat transfer coefficient, fill volume of PCM in heat sink and the shape of the electric pulse. It has been observed that the super cooling of Peltier cooler increases with increase in fill volume of PCM. Furthermore, it has been found that the super cooling performance of the Peltier cooler is more predominant with the square pulse as compared to ramp and triangular pulses.
