Thermal Storage for Big Spaces

A relatively new secondary refrigerant is being successfully applied in large-scale cooling applications, both as a heat transfer fluid and as a thermal energy storage (TES) medium for low-temperature stratified TES. Not only can this aqueous fluid be formulated in various concentrations to meet desired system operating temperatures, but it also exhibits useful properties that make it an attrac...
