Efficient elastocaloric drive system enabled by constant-torque and work-recovery design
Andrej Žerovnik, Stefano DallʹOlio, Simon Krašna, Žiga Ahčin, Jaka Tušek
Izvirni znanstveni članek
Oznake: elastocaloric cooling;drive systems;efficiency;
Elastocaloric cooling is a promising alternative to vapor-compression systems, offering high efficiency and reduced environmental impact. Despite significant advances in elastocaloric technology in recent years, limited attention has been given to the mechanical systems required to drive elastocalor ...

Oznake: elastokalorični učinek;materiali z oblikovnim spominom;regeneratorji;toplotne črpalke;elastocaloric effect;shape memory materials;regenerators;heat pumps;
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; h ...

Development of a tube-based elastocaloric regenerator loaded in compression
Stefano DallʹOlio, Žiga Ahčin, Andrej Žerovnik, Parham Kabirifar, Miha Brojan, Jaka Tušek
Pregledni znanstveni članek
Oznake: elastocaloric effect;shape memory alloys;buckling;elastocaloric regenerator;fatigue life;cooling;heat pumps;
In recent years, devices based on the elastocaloric effect (eCE) have emerged as one of the most promising alternatives to vaporcompression cooling and heating systems. After a brief overview of elastocaloric materials and elastocaloric devices developed to date, this paper reviews our recent activi ...

Performance analysis of a high-efficiency multi-bed active magnetic regenerator device
M. Masche, Jierong Liang, Stefano DallʹOlio, Kurt Engelbrecht, Christian Robert Haffenden Bahl
Izvirni znanstveni članek
Oznake: magnetocaloric effect;cooling performance;active magnetic regenerators;first-order phase transition;
We present the performance of an active magnetic regenerator prototype with a multi-bed concept and parallel flow circuit. The prototype applies a two-pole permanent magnet (maximum magnetic flux density of 1.44 T) that rotates over 13 tapered regenerator beds mounted on a laminated iron yoke ring. ...

Refrigeration is vital to the modern society; however, it is one of the most polluting sectors in the world. Despite decades of development, our standard vapor-compression technology remains relatively inefficient and still uses harmful refrigerants. Elastocaloric cooling has shown significant poten ...

Novel design of a high efficiency multi-bed active magnetic regenerator heat pump
Stefano DallʹOlio, M. Masche, Jierong Liang, A. R. Insinga, Dan Eriksen, Rasmus Bjørk, Kaspar K. Nielsen, Alexander Barcza, Hugo Vieyra, Niels V. Beek, Henrique Neves Bez, Kurt Engelbrecht, Christian Robert Haffenden Bahl
Izvirni znanstveni članek
Oznake: magnetic refrigeration;magnetocaloric effect;heat pumps;active magnetic regenerators;
The design of a rotary active magnetic regenerator heat pump device with a multi-bed concept is presented. Important design features are the rotating two-pole magnet assembly, the laminated iron ring, the 13 fixed tapered regenerator beds, and the dynamically adjustable parallel flow circuit. The op ...
