Refra » Ice banks
Ice banks are highly effective in air conditioning and refrigeration applications by addressing the common need for consistent cooling during peak demand periods. They store thermal energy in the form of ice, which is later used for cooling purposes. This makes them ideal for process cooling in industries such as food and beverage manufacturing. Refra ice banks can be integrated into flooded ice storage systems with Refra chillers or into direct expansion systems with condensing units or compressor racks. Their flexibility allows for customized configurations tailored to specific cooling needs, ensuring reliable and efficient operation.
Ice banks are widely used in commercial and industrial refrigeration where energy efficiency and reliable cooling are critical. The system operates by circulating a refrigerant or chilled glycol through coils installed inside a tank. During off-peak hours, typically at night, the coils freeze a layer of ice around them. Once the ice has formed, water circulates around the frozen coils, absorbing the cold and lowering its temperature. This chilled water is then distributed to meet cooling needs during peak demand periods. By shifting energy use to off-peak times and reducing the load on compressors during high-demand hours, ice banks deliver substantial energy savings. They ensure a steady, efficient cooling supply for applications such as process cooling, HVAC systems, and industrial refrigeration.
