Energy consumption reduction in a refrigeration system using phase change materials
This study is focused on the application of phase change materials (PCM) in low temperature systems, and the influence of using PCM in a domestic refrigerator is investigated. A type of eutectic PCM solution is added to the inner compartment walls of a household refrigerator by using commercially available PCM filled containers. Water is also used as a PCM and is added to the surface of the evaporator. The system is tested to determine the effects the PCMs have on the system. The effects of PCM on the refrigeration system are investigated by comparing the On-Off cycling of the system, total run time, and energy consumption with and without PCM. The benefit of PCM in the case of power outages is also investigated. The analysis of the results illustrates a significant improvement of the performance compared to a conventional refrigeration system. © 2018 International Institute of Refrigeration.
