Abstract
In this paper, we present the study and development of prototypes of refrigeration systems that operate more efficiently and consume less electrical energy, and this based on the use of Phase change materials (PCM) as thermal energy storage (TES). These materials have the ability to store thermal energy on its latent heat form, which is produced during off-peak periods, and then release this thermal energy to the consumer during the desired period or during periods when electrical demand is high. The effect of phase change material on the energy performance of a conventional refrigerator has been highlighted for two different evaporator configurations; a flat evaporator and a ventilated finned evaporator. An analysis to select the adequate phase change material (PCM) as well as its arrangement to be integrated into the refrigerator, and the mechanism by which the PCM affects the refrigerator operating conditions according to the type of evaporator has also been discussed.
