The thermal energy storage tanks store thermal energy in the form of chilled water. The system produces and stores chilled water during off-peak hours, then releases the stored cooling capacity during peak demand periods. By shifting cooling production away from peak operating hours, the thermal storage tank helps balance chiller system loads and improves overall energy management. The tank uses the natural density difference between chilled water and warmer return water to create thermal stratification. Cold water remains at the bottom of the tank, while warmer water stays at the upper section. A stable thermocline layer separates the two temperature zones and maintains effective storage performance.

During off-peak periods, chilled water produced by the chiller system is stored inside the TES tank. When cooling demand increases, chilled water is discharged from the bottom of the tank and supplied to the facility. At the same time, warmer return water enters from the top of the tank. The density difference between the two water temperatures creates natural stratification with minimal mixing between the cold and warm water layers. To maintain a clear thermocline layer, we apply an advanced diffuser design in the inlet and outlet piping. The diffuser controls water velocity and flow distribution to maintain smooth fluid movement inside the tank and reduce turbulence.
