Abstract—A preliminary study on the application of a model-based predictive control (MPC) of thermal energy storage in building cooling systems is presented. We focus on buildings equipped with a water tank used for actively storing cold water produced by a series of chillers.
Any chilled water cooling system may be a good application for thermal ice storage. The system operation and components are similar to a conventional chilled water system. The main difference is that thermal ice storage systems are designed with the ability to manage energy use based on the time-of-day rather than the cooling requirements.
Thermal Energy Storage (TES) is the term used to refer to energy storage that is based on a change in temperature. TES can be hot water or cold water storage where conventional energies, such as natural gas, oil, electricity, etc. are used (when the demand for these energies is low) to either heat or cool the storage water.
Like conventional chilled water systems, there may be seasonal changes initiated by a monthly date or ambient temperature. The ice storage control system may be interconnected to other large electric energy using equipment to provide energy management beyond just the HVAC components.
Thermal energy storage systems utilize chilled water produced during off-peak times – typically by making ice at night when energy costs are significantly lower which is then stored in tanks (Fig. 2 below).
A glycol fluid / chilled water heat exchanger will be used to separate the glycol and chilled water loops. The system will be a partial ice storage system. The design day cooling load profile has a cooling peak of 10.500 kW and a night cooling load of 11,000 kW to 1800 kW.
