Type of article: Article

Summary

The article presents evaluation of the performance of phase-change, thermal-energy storage units from the second-law viewpoint. The analysis is performed for a complete charging-discharging cycle of a system consisting of two storage units in series. The upstream unit has the higher of the two melting temperatures. The storage capacity of each unit is sized such that both units must change phase over the same period of time. A computer program is developed to find the dependence of the best second-law efficiency on different operational and design parameters.
