Summary
This study presents a numerical evaluation of integrating Phase Change Materials (PCMs) into the inner surfaces of cold room walls to enhance energy efficiency, product temperature stability, and energy flexibility. A dynamic cold storage model was developed using EnergyPlus co-simulated with MATLAB, considering both frozen and fresh product storage (e.g., fruits). The impact of PCM in terms of energy consumption and product temperature fluctuation. Results show that PCM integration effectively limits product temperature variations, improving thermal stability under various operating conditions. However, in most scenarios, energy savings remain negligible without implementing a cold production control strategy. When combined with an energy management strategy such as a Demand Response approach, PCMs enable load shifting and energy reduction while preserving product quality. This highlights the importance of active control strategies to unlock the full energy-saving potential of PCMs in cold storage applications.
