Summary

It is admitted that the integration of phase change material (PCM) in refrigeration systems has the potential to increase their flexibility, to stabilize product temperatures and in some cases to reduce their energy consumption. This study is about the impact of PCM used in a display cabinet. Two experimental set-ups are presented: the first one is an open display cabinet and the second one a closed display cabinet. A numerical model has been also developed and used to check the feasibility of PCM integration and evaluate its impact on the display cabinet. In addition, a parametric study have been carried out to highlight the importance of a display cabinet optimization after the insertion of PCM. Besides, PCM application in supermarket scenarios are discussed. The main results show the feasibility of PCM insertion, a significant increase of its thermal inertia, and the possibility to keep the compressor off during a few hours without temperature abuse for the products.
