A solar absorber can be used in a cold local heating network to regenerate and fill an ice storage tank. The absorber captures ambient heat from solar radiation, outdoor air, and precipitation and transfers it to the ice storage tank. This continuously supplies the storage tank with thermal energy, which can later be utilized via heat pumps for heating and hot water production.
This principle is particularly efficient because even low temperatures are sufficient to regenerate the ice storage tank. The solar absorber thus supports the seasonal use of ambient heat, increases the amount of energy available in the storage tank, and contributes to the stable operation of the cold local heating network.
air.FLOW - Modern Regenerative Air Absorber
Modern Absorber Technology Made in Germany
Modularly assembled capillary tube mats provide a very large heat exchange surface area. This allows a higher percentage of heat to be extracted from the air than with conventional air absorbers.
Diagram on the right: Air flows through the sp.ICE Airflow, capturing the warm ambient air (1). Stacked high-performance capillary tube mats provide a large heat transfer surface (2). The captured thermal energy is dissipated and used for the thermal regeneration of the ice storage unit (3).
