Ice Thermal Storage - Cost Saving Cooling for Office Buildings and Industries

Efficient cooling with off-peak electricity: Modern variants of the ice storage system significantly reduce the energy costs of air conditioning.

Ice thermal storages from BEKA [sp.ICE] combine an exceptionally efficient cooling performance with flexible installation and integration options in the existing air conditioning technology. The basis is formed by the proven capillary tube technology, which ensure a particularly high level of efficiency thanks to the large heat exchanger surface of the capillaries.

The capillary tube heat exchanger unit can be charged from a cooling temperature of -2 ° C. The ice storage cooling system is installed in a standardised container that can either be placed at ground level or as a basin in the ground. Depending on the required cooling capacity, there are three container sizes to choose from. Custom-made storage sizes are also possible.

Ice storage technology

Ice thermal storage is the modern variant of a technology that is thousands of years old and which adopts energetic processes in the transformation of physical states.

Whereas in the past it was primarily about storing ice for the cooling of food and its production processes in summer, today ice storage systems with short, daily charging cycles are required. As a rule, the ice energy storages are charged at night to reduce electricity costs and the stored cooling capacity is used during the day to cool offices or industrial productions.

Strengths of BEKA ice storages

  • Short charging and discharging cycles
  • Energy-saving ice generation
  • Modular construction
  • Ground or underground installation
  • Easy transportation
  • Low investment costs

sp.ICE - ice thermal storage in action

The modular BEKA ice storage systems with capillary tube mats as heat exchangers are currently used primarily in China, where the differences between day and night tariffs for electricity are particularly high and at the same time there is a great need for cooling.

In Germany, the Heidelberg-based GA-tec Gebäude- und Anlagentechnik GmbH operates two sp.ICEs with a total storage capacity of 4,200 kWh for cooling the offices of around 1,000 employees. We will be happy to provide further references on request.

By the way: The transfer of the cooling capacity to the room climate is particularly efficient in combination with a BEKA cooling ceiling. Our ceiling cooling systems with integrated capillary tube mats have energy advantages that are comparable to those of the ice storage system: high efficiency, fast reaction behavior and even cold and heat distribution thanks to large heat exchange surfaces.
