Scientists at the National Physical Laboratory (NPL) and Imperial College are working to make the inefficient method of refrigeration and air conditioning – which has been relied on for over a hundred years – a thing of the past.
A new project sets out provide a more economical, energy efficient and environmentally friendly cooling alternative. https://www.loiregrafix.fr/products/coque-samsung-galaxy-s4-mini-basketball-pascher-jil4507 https://www.loiregrafix.fr/products/amazon-coque-samsung-j7-6-pascher-jil2788 https://www.loiregrafix.fr/products/coque-samsung-s7-edge-mercedes-bln8969 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s4-tumblr-bln9736 https://www.loiregrafix.fr/products/coque-samsung-la-redoute-pascher-jil3357 https://www.loiregrafix.fr/products/coque-samsung-galaxy-core-prime-silicone-lapin-bln8171 https://www.loiregrafix.fr/products/coque-samsung-galaxy-j3-edition-2016-pascher-jil2321 https://www.loiregrafix.fr/products/coque-samsung-s8-carbone-pascher-jil3412 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s4-smiley-bln9850 https://www.loiregrafix.fr/products/coque-samsung-galaxy-sm-g361f-pascher-jil416 https://www.loiregrafix.fr/products/coque-samsung-galaxie-s5-new-pascher-jil336 coque wiko coque iphone coque iphone coque huawei coque iphone coque wiko coque wiko coque iphone coque huawei coque iphone The project will utilise the electrocaloric effect to develop new methods of cooling.
The electrocaloric effect is a phenomenon in which a material changes temperature under an applied electric field.
Current domestic refrigeration relies on a continuous cycle of compression and expansion of chemicals – known as vapour compression. https://www.loiregrafix.fr/products/cdiscount-coque-samsung-j7-2017-pascher-jil3935 https://www.loiregrafix.fr/products/coque-samsung-galaxy-sii-pascher-jil2436 https://www.loiregrafix.fr/products/coque-samsung-ace-amazon-pascher-jil1859 https://www.loiregrafix.fr/products/coque-samsung-j3-action-pascher-jil4623 https://www.loiregrafix.fr/products/coque-samsung-galaxy-grand-prime-humour-pascher-jil2340 https://www.loiregrafix.fr/products/coque-samsung-s9-plus-miroir-pascher-jil1481 https://www.loiregrafix.fr/products/nouvelle-coque-samsung-s8-pascher-jil3219 https://www.loiregrafix.fr/products/coque-samsung-galaxy-core-prime-adventure-time-pascher-jil1382 https://www.loiregrafix.fr/products/coque-huawei-p8-lite-or-pascher-xde31 coque iphone coque huawei coque iphone coque wiko coque iphone coque huawei coque iphone coque wiko coque wiko Freon gas, for example, can be cooled and condensed into a liquid. https://www.loiregrafix.fr/products/coque-samsung-a52017-pascher-jil276 https://www.loiregrafix.fr/products/coque-samsung-a3-2017-liquide-pascher-jil1525 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s10-bln7790 https://www.loiregrafix.fr/products/coque-samsung-galaxy-grand-prime-hockey-pascher-jil3339 https://www.loiregrafix.fr/products/coque-samsung-galaxie-j1-2016-pascher-jil2555 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s3-nike-pascher-jil4104 https://www.loiregrafix.fr/products/photo-sur-coque-samsung-bln8664 https://www.loiregrafix.fr/products/coque-samsung-galaxy-j3-pro-pascher-jil3785 https://www.loiregrafix.fr/products/coque-samsung-star-pascher-jil2276 https://www.loiregrafix.fr/products/coque-samsung-j3-photo-pascher-jil2174 coque wiko coque wiko coque iphone coque iphone coque huawei coque wiko coque huawei coque wiko coque iphone coque huawei This liquid then absorbs heat from the refrigeration area, causing it to re-evaporate, where it begins the cycle again.

Thermoelectric and magnetic cooling technologies have been put forward as environmentally-friendly alternatives to vapour compression. https://www.loiregrafix.fr/products/coque-samsung-grand-prime-minion-pascher-jil4901 https://www.loiregrafix.fr/products/coque-samsung-gt-19000-bln8905 https://www.loiregrafix.fr/products/coque-samsung-galaxy-tab-8-9-bln9851 https://www.loiregrafix.fr/products/coque-samsung-j5-pikachu-pascher-jil1341 https://www.loiregrafix.fr/products/coque-samsung-g920f-pascher-jil3171 https://www.loiregrafix.fr/products/priceminister-coque-samsung-j3-pascher-jil75 https://www.loiregrafix.fr/products/coque-samsung-lebron-james-pascher-jil1813 https://www.loiregrafix.fr/products/coque-samsung-a5-2016-camouflage-bln8465 https://www.loiregrafix.fr/products/coque-samsung-grand-prime-pascher-jil2784 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s6-edge-mickey-mouse-pascher-jil2502 https://www.loiregrafix.fr/products/coque-samsung-wave-723-pas-cher-pascher-jil4501 https://www.loiregrafix.fr/products/coque-samsung-galaxy-j1-verte-pascher-jil4723 coque iphone coque huawei coque huawei coque wiko coque iphone coque huawei coque iphone coque wiko However, these technologies struggle to compete with vapour-compression due to intrinsically low energy efficiency (maximum 10%), and the need for large and expensive magnets to generate the magnetic fields needed to run magnetic coolers.
However, as Maciej Rokosz – PhD student at NPL and Imperial – explains “An electrocaloric cooler, however, could potentially deliver higher efficiency than vapour compression – as the creation of an electric field requires less energy than the compression process to create the same level of cooling. https://www.loiregrafix.fr/products/huawei-p20-lite-coque-kpop-xiumin-pascher-xde72 https://www.loiregrafix.fr/products/coque-samsung-galaxy-note-3-lite-rosace-pascher-jil2142 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s5-rock-pascher-jil198 https://www.loiregrafix.fr/products/coque-samsung-galaxy-note-4-swag-pascher-jil1293 https://www.loiregrafix.fr/products/coque-samsung-tab-a-personnalise-pascher-jil4903 https://www.loiregrafix.fr/products/coque-samsung-s3-aliexpress-pascher-jil2934 https://www.loiregrafix.fr/products/coque-samsung-galaxy-j3-2016-starbucks-bln7923 https://www.loiregrafix.fr/products/coque-samsung-s8-fibre-de-carbone-pascher-jil3658 https://www.loiregrafix.fr/products/coque-samsung-a5-2017-cdiscount-pascher-jil4838 coque huawei coque wiko coque huawei coque iphone coque huawei coque huawei coque huawei coque iphone coque huawei coque wiko It could also offer reduced size and weight, making it viable for applications like cooling electronics.”
Tatiana Correia, a scientist at NPL who is leading the project, adds: “This project builds on considerable research and expertise that has been developed at NPL. https://www.loiregrafix.fr/products/coque-samsung-s5620-bln9647 https://www.loiregrafix.fr/products/coque-samsung-s7-edge-livraison-rapide-pascher-jil4879 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s7-edge-spigen-slim-armour-gunmetal-pascher-jil2719 https://www.loiregrafix.fr/products/coque-samsung-a42-pascher-jil2136 https://www.loiregrafix.fr/products/auchan-coque-samsung-s6-edge-bln8624 https://www.loiregrafix.fr/products/coque-samsung-a10-rouge-pascher-jil3967 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s5-quicksilver-pascher-jil3371 https://www.loiregrafix.fr/products/coque-samsung-edge-s6-pascher-jil2614 https://www.loiregrafix.fr/products/coque-samsung-galaxy-s7-360-pascher-jil2050 coque huawei coque iphone coque wiko coque huawei coque iphone coque iphone coque iphone Our experience in this area makes us confident that, over the next three years, we can develop the first electrocaloric refrigerator ever to operate close to room temperature”.
To support electrocaloric cooling technology, NPL is also developing and leading a new multimillion pound project funded by European Metrology Research Programme, METCO (Metrology of Electro-Thermal Coupling) which brings together Europe’s leading research centres and industry to develop unique capabilities for the traceable and accurate measurements of electrocaloric effect in materials.
Correia concludes: “We are confident that our design ideas, combined with the expertise we have at NPL and Imperial, will be able to develop a viable cooler.
