Dynamic modeling of encapsulated ice tank for HVAC system simulation

Dynamic system simulation facilitates the optimization of thermal storage s ystem design and operation. The models used for system simulation should mi nimize solution time, accurately simulate process response, and should appl y to a variety of products made by different manufacturers. This paper intr oduces an ice tank software model used for the thermal storage and HVAC dyn amic system simulation called TSTORS. It is a time dependent model for an e ncapsulated ice tank. Three groups of experiments with three different syst ems verify that the model applies to different types of encapsulated ice ta nks with different diameter ice balls. The model is also applicable to othe r ice tanks with such designs as non-spherical capsules or built-in metal c ores in the ice balls. For such tanks, the parameters needed for the model can be obtained from data provided by the manufacturers.
