“…In their study, the authors concluded that the transient power consumption could be reduced up to 26%. Sun et al [25] analyzed a single-tube, doublefinned row of a tube evaporator with phase change material in a refrigeration unit for food. Their results indicated that the charged PCM ensured the stable operation of the cold storage for a period after shutdown, and that economic savings could be achieved by taking advantage of peak and valley electricity prices.…”

This study concerns the numerical simulation and the experimental implementation of a low-scale Phase Change Material-based (PCM-based) condenser, to be included in a PCM-based portable cooling systems. In this category of cooling systems, the PCM can be integrated either in the condenser or in the evaporator. In the present study, the PCM is integrated in the condenser of the vapor compression cycle to absorb the heat power released from the refrigerant fluid (R134a) during condensation, thus eliminating the need to transfer heat to the external environment. The main objective of the present study is to realize and validate a numerical model capable of simulating both the refrigerant fluid and the PCM thermofluid dynamics. For this purpose, a commercial solver was used for the implementation of the developed numerical model, and experimental tests were performed to validate the numerical simulations results. The paper reports the details and test results of both the numerical model and the experimental apparatus. The simulation results indicate a good accordance between the numerical and experimental data.
