“…Although the trend in Figure 7 is similar to that for other storage systems during the discharging stage, it constitutes a new contribution to the field. Figure 8 depicts the effect of the input energy flow rate ( _ Q in ) on the discharge temperature of the TES, based on equation (13). From Figure 8, it can be observed that: • Increasing the input energy flow rate in the charging stage increases the discharge temperature during the TES discharge, especially in the early periods.…”

Summary Thermal energy storage (TES) is an important technology for effective and efficient energy management. The proper design and operation of a TES require an understanding of its behavior and characteristics. Here, the transient behavior during charging and discharging of a fully mixed, open TES is modeled and analyzed. Included are developments and analyses of the charging temperature function and the maximum charging temperature of the TES, the charging energy flow function and the maximum heat flow capacity of the TES, the discharging temperature function and the minimum charging temperature of the TES, the discharging energy flow function and the maximum heat flow capacity of the TES, and the expression for one cycle of the TES. The impact of various factors on charging and discharging are investigated. The results show that, by increasing the input energy flow rate, the charging temperature of the TES is raised, and that an increase in the input energy flow rate raises the discharging temperature of the TES in the early stage of discharging, while a decrease in the outlet energy flow rate increases the discharging temperature of the TES in the late stage of discharging.

In practice, there are some conditions, depending on space availability, economics, project requirements, insulation, storing media type and other issues, for which it may be advantageous to utilize several thermal energy storages (TESs) instead of one in thermal networks like district energy systems. Here, various configurations for multiple TESs are proposed and investigated. Significant parameters for a TES, or a set of TESs, include discharging temperature and recovered energy. First, one TES is investigated to determine the final temperature and energy recovery. Next, characteristics for various configurations of multiple TESs are developed as functions of TES characteristics (e.g., charging and discharging temperatures and energy quantities). Series, parallel and general grid (simultaneous series and parallel) TES configurations are considered. In the parallel configuration, the TESs behave independently. This suggests that with the TES can consist of different storage media types and sizes, and that there is no restriction on initial temperature of the TES. In the series configuration, the situation is different because the TESs are connected directly or indirectly through a heat exchanger. If there is no heat exchanger between the TESs, the TES storage media should be the same, because the outlet of one TES is the inlet to the next one in the series. The initial temperature of the second TES must be smaller than the discharge temperature of the first. There is no restriction on the TES size for series configurations. The general grid configuration is observed to exhibit characteristics of both series and parallel configurations.
