Multiple charging/discharging cycles are controlled for optimal chiller loading. Both thermal storage and chilled water temperature are optimized. The integration of thermal energy storage in chilled water systems is an effective way to improve energy efficiency and is essential for achieving carbon emission reduction.
The stratified chilled water storage tank was modelled as a “virtual chiller” to quantify the energy consumption related to the charging/discharging. Multiple charging/discharging cycles were controlled for optimal chiller loading. The proposed control strategy was evaluated in a simulated complex central chilled water plant.
Chilled water storage (CWS) is one of the most popular and simple thermal energy storage forms, using insulated water tanks to store chilled water that is generated with conventional chillers.
The results showed that 6.8%–9.4% of total energy consumption could be saved. Other scholars focused on scheduling the charging/discharging flow rate of storage tanks to increase the chiller's operating time in the high efficiency zone, thus improving system energy efficiency.
Chilled water systems typically store supply water at 39°F to 42°F, which is compatible with most water chillers and distribution systems. Return temperatures are typically in the range of 55°F to 60°F or higher. Stratified low-temperature-fluid TES systems operate similarly but with lower supply temperatures, typically between 29°F and 36°F.
When charging the tank, the warm water is taken from the top of the tank and sent to the chiller, while the chilled water is returned to the tank near the bottom. Chilled water storage tanks require a large footprint to store the large volume of water required for these systems.
