Abstract

In this article, a brief introduction of conventional refrigeration is given, followed by a description and history of magnetic refrigeration. The active magnetic regenerator comprises 12 parallel plates of magnetocaloric material (gadolinium (Gd)), through which circulates the heat transfer fluid (water, in this case). At both ends of the regenerator are the heat exchangers. The hot heat exchanger (HHEX) and the cold heat exchanger (CHEX) connects the fluid to the heat sources. The principle of operation of a magnetic refrigeration installation is based on exploiting the magnetocaloric effect from the materials that possess these properties (in this case, Gd).

Secondary abstract:	V tem članku je uvodoma opisano kompresorskego hlajenje, ki mu sledi opis in zgodovina magnetnega hlajenja. Aktivni magnetni regenerator obsega 12 vzporednih plošč magnetokaloričnega materiala (gadolinij (Gd)), skozi katerega kroži tekočina za prenos toplote (v tem primeru voda). Na obeh koncih regeneratorja sta izmenjevalnika toplote. Vroči izmenjevalnik toplote (HHEX) in hladni izmenjevalnik toplote (CHEX) povezujeta tekočino z viri toplote. Načelo delovanja magnetne hladilne naprave temelji na izkoriščanju magnetokaloričnega učinka materialov, ki imajo te lastnosti (v tem primeru Gd).
