Institute of Air Handling and Refrigeration

ILK Dresden (the Institute of Air Handling and Refrigeration) is your competent partner for research and development tasks in the fields of air handling and refrigeration technologies and their applications. Our strength consists in the wide range of our research fields and technologies as well as in their mutual integration. We pursue practical research, development and technology transfer to be directly applied by companies and society. For this purpose, we use the latest in procedures and methods in applied research and development.

Short description of the project contribution

Ice storage with vacuum liquid ice technology to flexibilise industrial refrigeration systems by means of Power-to-Cold

14 per cent of Germany’s electricity demand is used to generate cold. In other regions of the world, this share is significantly higher, even up to 60 per cent. The sub-project aims to make this already existing and previously largely demand-oriented power consumption as flexible as possible by using an efficient and flexible ice storage process in industrial applications with high cooling loads, thus expanding the application potential of Power-to-Cold (PtC).

By further developing the vacuum liquid ice process, the range of application of this efficient and highly flexible ice storage technology can be expanded to widely used refrigeration applications with temperatures to minus five degrees Celsius.

In the scope of the project, a demonstrator is created with a storage / ice generation capacity of 500 kilowatt, which is combined with a liquid ice storage unit into a complete system.
