20.500.12556/RUL-142647 High-performance cooling and heat pumping based on fatigue-resistant elastocaloric effect in compression In recent years, elastocaloric cooling has shown great potential as an alternative to vapor-compression refrigeration. However, there is still no existing elastocaloric device that offers fatigue-resistant operation and yet high cooling/heat-pumping performance. Here, we introduce a new design of an elastocaloric regenerator based on compression-loaded Ni–Ti tubes, referred to as a shell-and-tube-like elastocaloric regenerator. Our regenerator design, which can operate in both cooling and heat-pumping modes, enables durable operation and record performance with a maximum temperature span of 31.3 K in heat-pumping mode or maximum heating/cooling powers of more than 60 W, equivalent to 4,400 W/kg of the elastocaloric material (at temperature span of 10 K). In terms of both maximum performance metrics, these results surpass all previously developed caloric (magnetocaloric, electrocaloric, and elastocaloric) devices and demonstrate the enormous potential of compression-loaded elastocaloric regenerators to be used in elastocaloric devices for a wide range of cooling and heat-pumping applications. elastocaloric effect caloric cooling heating heat-pumps shape-memory alloys tubes Ni–Ti compressive loading fatigue efficiency fatigue efficiency elastokalorični učinek hlajenje ogrevanje toplotne črpalke regenereatorji Ni-Ti materiali z oblikovnim spominom trajno-dinamična trdnost true false true Angleški jezik Slovenski jezik Članek v reviji 2022-11-17 14:59:05 2022-11-17 14:59:08 2024-03-01 11:16:59 0000-00-00 00:00:00 2022 0 0 Str. 2338-2357 iss. 10 Vol. 6 Oct. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.3 2542-4351 10.1016/j.joule.2022.08.011 122510851 Ahcin_...-High-performance_cooling_and_heat_pumping_based_on_fatigue-resistant_elastocaloric_effect_in_compression.pdf Ahcin_...-High-performance_cooling_and_heat_pumping_based_on_fatigue-resistant_elastocaloric_effect_in_compression.pdf 1 EC537882F58FE0A027232EBC2E56687D 52bd5893c1691e88e875c9a5481f068099d075472eed5932adb727b8c8b8c963 4c427631-6680-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164094 https://www.sciencedirect.com/science/article/pii/S2542435122004123 1 e3b9d38c-667f-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=164093 Fakulteta za strojništvo 0 0 0
