FAQs

Your thermal energy storage questions, answered.

Ice-based thermal energy storage is a system that uses ice to store cooling or heating energy. During off-peak hours, a chiller produces ice, which is stored in tanks. This stored energy is then used to provide cooling or heating during peak hours, reducing the need for chiller operation when electricity rates are higher.

Ice-based thermal energy storage works by utilizing a chiller to freeze water mixed with glycol in storage tanks during off-peak hours. The ice is built uniformly around a heat exchanger inside the tank. During peak hours, the stored ice melts, cooling the glycol solution, which is then circulated to meet the building's thermal management load.

Ice-based cooling provides cost-efficient thermal management by shifting the cooling load to off-peak hours when electricity rates are lower. This reduces the demand charges associated with peak electricity usage. Additionally, the system can allow for a smaller chiller size (partial storage), helping to lower initial costs and operational expenses. The use of stored ice for thermal management also helps in managing energy consumption and costs more effectively.
