UPORABA REGENERATORJA ZA MAGNETNO HLAJENJE
Povzetek
V tem članku je proučen mehanizem in delovanje hladilnega sistema, ki temelji na magnetnem sistemu in magnetokaloričnem učinku. Magnetne hladilne naprave delujejo po najsodobnejši tehnologiji, ki ne vsebujejo nobenega strupenega hladilnega sredstva, ki je škodljivo za okolje in ozonski plašč. Magnetokalorični učinek ustvarja redka zemeljska kovina, imenovana goldonij. Proučevali smo prednosti uporabe tovrstnih mehanizmov tako za domače kot industrijske potrebe. Za to vrsto namestitve je značilna visoka učinkovitost in nizka poraba energije. Predstavljen članek opisuje začetni prototip za AMR v smislu magnetokaloričnega hlajenja.
