Once a month, we talk with our Japan-based source in order to find out interesting things from the auto industry and today he revealed us some pretty interesting things. It appears that Nissan currently working on a new air conditioning system using a magnetic field. For those who don’t know, the current heating and cooling devices use a vapor compression system.
This system uses a gas such as chlorofluorocarbon and needs lots of energy, but the main issue is that the gas is associated with environmental problems. Well, things are about to change and Nissan is interested in using the same principle as the magnetic refrigerator.
This cooling technology is actually based on the magnetocaloric effect and the first persons to observe this effect were French physicist P. Weiss and Swiss physicist A. Piccard in 1917, according to Wikipedia.
So, how does this work? Well, it is actually pretty complicated but we had to study the method and we will try to explain you folks too.
The magnetocaloric effect or MCE is a magneto-thermodynamic phenomenon in which a temperature change can be caused by exposing the material to a changing magnetic field. Regarding the debut of the new technology we actually don’t have a clue, but we do expect it on a new fancy concept. You can find more details regarding the magneto-thermodynamic phenomenon on Wikipedia.org.
