MagMed 2 project
Magnetocalorics: Development of a refrigerant-free, efficient cooling technology
The aim of the project is to develop a medical refrigerator based on the magnetocaloric effect that guarantees a storage temperature of 4 – 18 °C and uses water as its fluid. Compared to devices that operate with currently available technologies, the refrigerator is to be characterized in particular by higher efficiency.
In the preceding MagMed 1 project, the functional principle based on thermal diodes and a latent heat transport could successfully be confirmed. In particular, a very high specific cooling capacity of 12.5 W/g was achieved – a value that by far exceeds the state of the art.
In MagMed 2, the task will be to demonstrate the long-term stability of the system at high system efficiency. This involves mastering the technical challenge posed by the use of water as the fluid.
The first market to be addressed in this project remains medical technology, which lends itself as a pilot market as it is an application area with sufficiently high sales potential and comparatively low pricing pressure. After a successful market launch, magnetocalorics has the potential to gradually replace compressor technology in many other applications, e. g. households, industry, commerce and transport.
