Like conventional chilled water systems, there may be seasonal changes initiated by a monthly date or ambient temperature. The ice storage control system may be interconnected to other large electric energy using equipment to provide energy management beyond just the HVAC components.
The building technology company leitec® took a different path: an ice energy storage system provides the necessary energy. WAGO technology controls the interplay among the systems, plus all the building automation. Energy is created when water freezes to form ice.
These are the following operating modes: heating using the ice energy storage system, heating using the solar thermal collectors installed on the roof next to the photovoltaic modules, cooling the ice energy storage system, regeneration using the solar collectors and cooling with the heat pump.
Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. Alternative power sources such as solar can also use the technology to store energy for later use.
Viessmann exploits this principle with their ice energy storage system. The combination of heat pumps and ice energy storage functions most efficiently when used to generate both heating and cooling. In the winter, the heat pump withdraws energy to ensure that the water tank freezes from the inside out.
Their ice energy storage system, consisting of an underground cement tank ten meters in diameter and six meters deep, holds up to 400,000 liters of water. “The system works quite well,” says Bernd Apitz, CEO and owner of leitec®. “We were among the first companies to build an ice energy storage system of this magnitude.”

Using ice and snow in thermal energy storage systems
When all the water is frozen, the doors are closed as the storage is now filled with cold. Then, it works like the snow storage illustrated in Figure 8.2. Provided that the doors are opened and closed to freeze the water in due time, such ice storage systems are self-sustained and work for decades without replacing the water.
