A novel household refrigerator with a phase change material (PCM) heat exchanger:An experimental investigation
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
In this study, a phase change material (PCM) was adopted for constructing heat storage-PCM heat exchanger with a setup based on an ordinary single-door refrigerator.The experimental investigation of the characteristics of the novel refrigerator and an ordinary refrigerator was carried out. For the novel refrigerator, the PCM heat exchangerat the evaporator,has replaced the heat transfer mechanismwith the higher rate heat transfer mechanism of a combination of conduction and convection process during on-time. And the heat gain to the system was absorbed by PCM during the off-time.Thus, the overall heat-transfer performance of the evaporator with PCM heat storage exchanger could be significantly improved. This has resulted in a lower condensation temperature, a greater stability of temperature inside cabinet. Compared to the ordinary refrigerator, the ratio of on-time to the total cycle timeof novel refrigerator was much smaller, which led to lower energy consumption. Experiments demonstrated that the novel refrigerator could increase the COP of system by 21.5% and energy efficiency by about 15% withthe least cost addition.
