Cool Thermal Energy Storage is a new application of an old idea that can cut air conditioning energy costs in half while preparing your building for the future. Air conditioning of commercial buildings during summer daytime hours is the largest single contributor to electrical peak demand.

How efficient is a thermal energy storage system?

The heat loss in the thermal energy storage system is 0.5 °C (Development Bank of Latin America 2015), which makes the system ~ 95% efficient, assuming that a 10 °C temperature difference of the stored cold water is used in the cooling process.

What is the difference between a storage system and air conditioning system?

Capital costs incurred are comparable to conventional air-conditioning system, with cost saved by using a small refrigeration plant. Storage systems let chillers operate at full load all night instead of operating at full or part load during the day.

Why are energy storage systems important?
