| dc.description.abstract | A personalized mobile cooling device was modified and tested with different components to deliver better system performance. The device uses a miniaturized vapor compression cycle (VCC) to deliver approximately 165 W of cooling to an individual. The device stores the waste heat from the VCC condenser in a phase change material (PCM) carried on-board the device. The PCM is then recharged by rejecting heat stored in the PCM with a thermosiphon recharge cycle. The PCM was enhanced with copper and graphite matrices. The system was tested with the goal of increasing the coefficient of performance (COP) of the VCC and decreasing the PCM recharge time. This study found that a copper enhancement provided the highest COP at 4.43, an improvement over the baseline COP of 2.41. | en_US |
