Power, Efficiency, and Irreversibility of Latent Energy Systems

The object of this paper is to present a simple model for the latent storage systems by using a phase-change material encapsulated in the spherical capsules. When designing phase-change-material systems, it is important to minimize thermal irreversibilities, because it works best when irreversibilities are done. In this paper, second law analysis is used to evaluate the irreversibility of the system. The effects of different parameters are also discussed. The proposed model can be applied to the charge and the discharge mode. Exergy efficiency is also evaluated.
