Résumé

Thermal energy storage applications such as solar space heating systems in houses and cooling systems for refrigeration are able to use phase change materials (PCMs) to store heat or cooling. As PCMs can store large amounts of heat or cooling in a small amount of material, they potentially have less weight and volume compared with other thermal energy storage materials. They also absorb and release heat at a relatively constant temperature. However, specifying a PCM system has been difficult in the past because it has been intricate to predict the heating or cooling capacity from the system. This paper presents the results of an experimental investigation carried out on tubes carrying a heat transfer fluid in a phase change thermal energy storage system for cold storage applications. Experiments involved using one and two lengths of tubes in a PCM filled cylindrical tank. The PCM used is a salt hydrate with phase change temperature of -27°C. From the experimental measurements, the effectiveness of the storage tank was determined and a characteristic design curve has been developed.
