Energy storage ice pack for quick freezing

How does thermal ice storage work?

Thermal ice storage is a technology that can store excess electricity capacity from the sun or wind and convert it into 'cold' thermal energy by freezing water into ice. This ice is then used later to feed into the cooling network during periods of need. In this application, the ice storage system also contributes to smoothing the load on the electricity grid.

What is thermal ice storage?

Thermal ice storage is a technology that provides a cap on peak cooling demand. During periods when the existing cooling technology is not fully utilized, the storage is charged. The stored energy is then fed back into the system when required. This alignment of refrigeration technology with the average demand allows for more economical dimensioning.

What are ice storage systems?

Ice storage systems are modern variants of a millennia-old technology that have harnessed the energetic process of latent heat.

What is ice storage heating?

Ice storage heating, also known as this, involves the use of a heat pump to freeze water in a storage tank. In this application, the frozen ice is used to cool the rooms in summer. The system may have a long charging and discharging time.

Why should ice storage tanks be filled at night?

Ice storage tanks are usually filled at night because it takes advantage of reduced electricity costs. The stored cooling power is then used during the day to cool offices or industrial processes, requiring significantly less energy than direct cooling at the time of cooling demand.

Why do we need a fast-reacting thermal ice storage system?

A fast-reacting thermal ice storage system is necessary if it is to cover the peak cooling demand during the day or the entire cooling demand of one day. It must absorb the entire energy during the few night hours and dynamically release it again during the day when cooling is required.
