20.500.12556/RUL-127890 A regenerative elastocaloric heat pump A large fraction of global energy use is for refrigeration and air-conditioning, which could be decarbonized if efficient renewable energy technologies could be found. Vapour-compression technology remains the most widely used system to move heat up the temperature scale after more than 100 years; however, caloric-based technologies (those using the magnetocaloric, electrocaloric, barocaloric or elastocaloric effect) have recently shown a significant potential as alternatives to replace this technology due to high efficiency and the use of green solid-state refrigerants. Here, we report a regenerative elastocaloric heat pump that exhibits a temperature span of 15.3 K on the water side with a corresponding specific heating power up to 800W1/kg and maximum COP (coefficient-of-performance) values of up to 7. The efficiency and specific heating power of this device exceeds those of other devices based on caloric effects. These results open up the possibility of using the elastocaloric effect in various cooling and heat-pumping applications. elastocaloric effect regenerative thermodynamic cycle heat pumps elastokalorični učinek regenerativni termodinamični krožni proces toplotne črpalke true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-28 11:08:33 2021-06-28 11:08:38 2022-09-06 03:53:39 0000-00-00 00:00:00 2016 0 0 Str. 1-6 iss. 10, art. 16134 Vol. 1 Oct. 2016 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-03-05 697:621.577(045) 2058-7546 10.1038/nenergy.2016.134 14935067 RAZ_Tusek_Jaka_2016.pdf RAZ_Tusek_Jaka_2016.pdf 1 08631684864536E13B6E75254DD11CB6 cefebd3c028465f1092f6b96825b010ceb6764cfb3bdef6cba4f410e96251e7e 167c4091-d7f2-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144455 http://www.nature.com/articles/nenergy2016134 1 4f4a18ea-d7f0-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=144454 Fakulteta za strojništvo 0 0 0
