Abstract
This paper presents the details of a mathematical model that is used to predict the charging performance of ice storage for stacked rectangular capsules. The phase-change material (water) is held in flat, rectangular capsules that are stacked on top of each other with spacing in between successive capsules in order to provide flow channels for the heat transfer fluid. The model takes into account the detail of the supercooling phenomenon of water that has effects on the characteristics of encapsulated ice storage. The effects of water supercooling degree and coolant mass flow rate on the charging performance are discussed in detail. The numerical results show that the time needed to store ice is significantly shortened while the supercooling degree of water decreases.
