How does the ice energy storage system work?
The ice energy storage tank contains approx. 237,000 litres of water. There are also about 1,900 m of pipes in the heat exchanger system. A mixture of water and antifreeze runs through these plastic pipes.
This mixture extracts the heat from the water and transports it to a heat pump located in our basement, where the water-antifreeze mixture meets a refrigerant, which generates heat and evaporates the mixture.
The heat pump then compresses the now gaseous mixture, heating it to 70 degrees Celsius. The resulting steam transfers the heat to a heating circuit in the building - in our case, the underfloor heating.
During this process, the water in the ice storage system continues to cool, with the movement of the water molecules being reduced further and further as it does so.
