The first magnetic refrigerator from Denmark!

magnetic fridge The first magnetic refrigerator from Denmark!

A group of researchers at the Technical University of Denmark’s project laboratory in Risø have discovered a cooling method that uses magnetic materials instead of electricity, reported daily free newspaper Nyhedsavisen.

The invention will allow for refrigerators to replace existing electric refrigerators in homes and businesses with a fully environmentally friendly power source. Although the first prototype will not be ready until 2010, the project’s researchers say the appliance’s cooling cycle efficiency will be 60 percent greater than that of conventional refrigerators.

The new method uses opposing magnetic fields to increase the temperature of the materials employed. The heat energy is transported through a non-volatile fluid, such as water, and then thermodynamically reversed to a cold temperature. The scientists have already been able to cool a 20° C room to 11°C using the new technology.



‘It probably isn’t realistic to believe that magnetic cooling technology will be immediately available for consumer use, especially as refrigerator manufacturers have brought prices down so much in the past few years,’ said Christian Bahl, one of DTU’s project researchers.

But Bahl said another of the magnetic refrigerator’s advantages is that it is silent.

‘So it will likely be first used in various niche areas, such as places where a quiet environment is an important factor.’

Although magnetic cooling is not in itself a new research field, the DTU scientists were the first to use the technology in an actual physical setting to cool room temperatures.

    This technology can’t replace electric refrigerators in the absolute sense.
    Electricity will still be needed to pump the fluid and run other functions, even
    if they are able to accomplish the other things implied by this article.

    Info is not accurate. Check Wikipedia for more info…Danish group has not doen anything new yet!!

    Magnetic cooling has no magic behind, we have working model since 1933. The principle behind it never break any rule of physics. Nowaday researchers from all over the world are working on how to make it marketable. More important, it has nothing to do with “Magnetic Power”.
