Dear friends, we present you this week, as a innovation a piece of new that would change definitely the way of conceiving the refrigeration.
Recently, these days we have been able to hear numerous references to an important break-through in different technological media about an important step-ahead in the refrigeration sector.
Some reputed researchers from different universities namely the Massachussets Institute of Technology in Cambridge and the Newcastle University in Australia, have carried out some investigations on magnetic nanoparticles (iron oxide) referring to industrial installations.
This new technique may find its place not only in the industrial sector but also in the refrigeration of electrical appliances and even in nuclear fusion reactors.
The previously mentioned uses water to eliminate the surplus heat. This could be substituted by using magnetic nanoparticles to cool the system. By doing so, they may improve the heat transfer in the refrigerating systems when using water and this way would prevent any failures through overheating. This improvement would be far better than the previous or conventional methods which work with fins by dispersing the heat over the surface of the tubes. This way the transfer heat would be distributed from the fluid through the tube walls to the outside air.
In the photograph you can check one of our heat exchangers, in the process of being assembled and with this system would consist on eliminating these fins.


 These specialists have remarked that the heat coefficient is higher than by working with water. In particular, approximately around 300% and this would help the system to operate more efficiently and we could save more energy and avoid an increase in the pressure drop.
To conclude in a not too distant future we can hope to discover new ways of saving energy, being more efficient and working in a more economical way in order to facilitate the work for the technological field. Without as knowing it these advances will be creeping into our homes and make our life easier.
Time will tell.
