Iceberg cold and hot energy storage concept

What is ice energy storage?

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.

Do ice thermal storage systems reduce energy consumption?

One case study was conducted by employing the ice thermal storage systems for office building applications . The comparison results between the conventional AC system and the latent TES system indicate that a proper design could lead to lower energy consumption due to better utilization of the equipment.

What are the operating modes of the ice energy storage system?

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.

What is a heating and Cooling Supply using ice storage?

Conceptual representation of a heating and cooling supply using ice storage. A cooling liquid, also called brine, flows through the pipes. The freezing point of this fluid is well below 0°C. If the brine temperature is lower than that of the water in the ice store, the ice store gives off heat.

What is cold thermal energy storage?

Cold thermal energy storage (TES) has been an active research area over the past few decades for it can be a good option for mitigating the effects of intermittent renewable resources on the networks, and providing flexibility and ancillary services for managing future electricity supply/demand challenges.

How does an ice energy storage system work?

Because the ice thaws slowly and reaches a higher energy level during melting, heat is stored again for the winter. The ice energy storage system operates even more economically when the electricity required to operate the heat pump is self-produced. At leitec®, photovoltaic modules on the roof provide most of the power.
