Abstract
A phase-change energy storage system consisting of sections of different materials with different melting temperatures is proposed for air conditioning applications. The Phase Change Materials (PCMs) are placed in thin flat containers and air is passed through gaps between them. A semi-analytical model has been developed and calculations carried out using the finite elements method. Results obtained from three models with different assumptions are compared. The effect of the design parameters such as, PCM slab thickness and fluid passage gap on the storage performance is also investigated. The system is being developed for energy storage in solar heating and energy efficient space heating and cooling applications.
