Abstract
The use of indirect evaporative cooling in dry weather conditions to charge phase change materials (PCMs) storage systems can reduce overall energy consumption. Lower thermal conductivity is the main limitation of PCM, so a suitable technique must be used to enhance thermal conductivity. The use of PCMs thermal energy storage in cooling systems could reduce the electric energy cost by shifting the peak load to an off-peak period. Studies showed that the selection of PCMs for free cooling applications is critical because it depends on the outside temperature at the charging period. Therefore, the outside temperature should be lower than the solidification temperature of the PCMs during charging, and the melting temperature should be lower than the inside temperature during the discharging process. The objective of this review article is to evaluate current phase change materials applications in cooling systems. The investigations about the application of PCMs in cooling systems undertaken by different researchers will be described in this article. Free cooling and heating system using building envelop, free cooling and heating using Air Handling Unit latent heat thermal storage systems, air conditioning, and refrigeration systems are discussed briefly. About 35% of these studies used PCMs used in roofs, ceilings, and attics.
