Simulation of chiller water storage / Hafiz Zaim Hussin

Chilled water storage systems are used in commercial buildings to shift the timing of cooling energy purchase from on-peak periods. Typically, this is done by chilling water during the night, storing it in a tank, and drawing from it during the day to provide space cooling. This reduces building ele...
