KEY POINTS
When rubbers bands are twisted and untwisted, it produces a cooling effect. This is called the “elastocaloric” effect.
Reduction in global arming
· Researchers from multiple universities have found that the elastocaloric effect, if harnessed, may be able to do away with the need of fluid refrigerants used in fridges and air-conditioners.
· These fluids are susceptible to leakages, and can contribute to global warming. The results of the research were published in the journal Science on Friday.
· To demonstrate this setup, the researchers developed a fridge the size of a ballpoint pen cartridge that was able to bring down the temperature of a small volume of water by 8°C in a few seconds.
· They suggested that their findings may lead to the development of greener, higher-efficiency and low-cost cooling technology.
Advantages of Elastocaloric Refrigeration
· More efficient than vapor-compression refrigeration as the twisted rubbers are used
· No gases or volatile liquids involved since there is no need for refrigerants
· Non-hazardous, reducing GHG emission and environment friendly
· Re-usable and recyclable parts and components
