The FAFCO ice storage, the ICEBAT, is a system of submerged tube exchangers. It uses the solidification of water into ice to store cold in the form of “latent heat”. ».
Water is indeed the best phase change material (PCM) for cold storage: available everywhere, economical and without impact on the environment, water has the greatest latent heat of all known liquids. For specific applications, FAFCO offers 2 other PCMs for positive and negative temperature storage, with phase changes at +10°C and -10°C.
During the charging phase, the cold brought by the glycol water circulating through the exchangers transforms the water stored in the ICEBAT into ice.
In the discharge phase, the customer’s hot fluid is cooled by passing through FAFCO exchangers trapped in ice.
ICEBATS are 8 times more compact than chilled water storage of equivalent capacity.
Reduction of the electrical connection power.
Optimization of energy consumption for the air-conditioning of buildings.
Emergency cooling capacity in case of power failure.
Reduction of the power of the refrigeration units.
Reduced environmental impact.
