20.500.12556/RUL-113725 Elastocaloric cooling state-of-the-art and future challenges in designing regenerative elastocaloric devices Elastokalorično hlajenje: pregled razvoja in nadaljnji izzivi pri razvoju regenerativnih elastokaloričnih naprav The elastocaloric cooling, utilizing latent heat associated with martensitic transformation in shape-memory alloys, is being considered in the recent years as one of the most promising alternatives to vapour compression cooling technology. It can be more efficient and completely harmless to the environment and people. In the first part of this work, the basics of the elastocaloric effect (eCE) and the state-of-the-art in the field of elastocaloric materials and devices are presented. In the second part, we are addressing crucial challenges in designing active elastocaloric regenerators, which are currently showing the largest potential for utilization of eCE in practical devices. Another key component of elastocaloric technology is a driver mechanism that needs to provide loading for active elastocaloric regenerators in an efficient way and recover the released energy during their unloading. Different driver mechanisms are reviewed and the work recovery potential is discussed in the third part of this work. elastocaloric effect cooling active elastocaloric regenerators fatigue life driver mechanism elastokalorični učinek hlajenje aktivni elastokalorični regeneratorji doba utrujanja pogonski mehanizem true false true Angleški jezik Slovenski jezik Članek v reviji 2020-01-29 13:24:35 2020-01-29 13:24:39 2022-08-26 03:47:11 0000-00-00 00:00:00 2019 0 0 Str. 615-630 no. 11/12 Vol. 65 Nov./Dec. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.57:620.178.37(045) 0039-2480 10.5545/sv-jme.2019.6369 16941851 762116 RAZ_Kabirifar_Parham_2019.pdf RAZ_Kabirifar_Parham_2019.pdf 1 5151CB304AE6F0CD153364592BC532F1 2d81e819cdac4c708f3413d73267e72114a0b0a62983109a9524cefa71ae0f08 25326747-a1b8-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125821 https://www.sv-jme.eu/sl/article/elastocaloric-cooling-state-of-the-art-and-future-challenges-in-designing-regenerative-elastocaloric-devices/ 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=125820 Fakulteta za strojništvo 0 0 0
