Chilled Water Thermal Energy Storage and Management

Chilled water systems and thermal energy storage (TES): Adding a centralized chilled water system can be a solution for battery storage requiring 500 tons of cooling or more. This technology can provide cooling at an approximate demand of 0.6 kilowatts (kW) per ton or less, compared to DX units using an average 1.2 to 1.4 kW per ton.
