Ngokweengxelo zeendaba zasekhaya, iinjineli zaseRussia zikwazile ukwenza ifriji yesizukulwana esitsha. Into ephambili eyahlukileyo yophuhliso kukuba into esebenzayo ayilulwelo olujika lube yigesi, kodwa isinyithi samagnetic. Ngenxa yoko, izinga lokusebenzisa amandla linyuka ngama-30-40%.
Uhlobo olutsha lwefriji lwenziwa ngabanjineli beNational Research Technological University "MISiS", esebenzisana noogxa baseTver State University. Isiseko sophuhliso olubonakalisiweyo yinkqubo yamagnetic eqinile, ehambelana nokusebenza kwamandla ngama-30-40% ngaphezu kweendlela ze-compressor zegesi ezisetyenziswa kwiifriji eziqhelekileyo. Xa udala inkqubo entsha, isiphumo se-magnetocaloric sisetyenzisiwe, eyona nto kukuba xa i-magnetized, i-magnetic material iguqula ukushisa kwayo. Enye yeempawu zophuhliso kukuba abaphandi bakwazile ukufezekisa umphumo we-cascade. Imivalo yeGadolinium efakwe kwivili elikhethekileyo ijikeleza ngesantya esiphezulu, ngenxa yokuba iwela kwintsimi yamagnetic.
Ababhali beprojekthi bathi iteknoloji abayisebenzisayo ikhona malunga ne-20 iminyaka, kodwa eli lixesha lokuqala lokuba umgaqo we-cascade uphunyezwe ngempumelelo. Ufakelo oludalwe ngaphambili alukwazi ukusetyenziselwa ukupholisa okuqinileyo, kuba bayakwazi ukugcina ubushushu obuthile.
Kwixesha elizayo, abaphuhlisi bazimisele ukuqhubela phambili ukuphuhliswa kweteknoloji ye-cascade, ngenxa yokuba baceba ukwandisa uluhlu lweqondo lokushisa lokusebenza kwefriji. Kuyaphawuleka ukuba ubungakanani benkqubo yebhubhoratri abukho ngaphezu kwe-15 cm.
