Malinga ndi malipoti apanyumba, akatswiri aku Russia adakwanitsa kupanga firiji ya m'badwo watsopano. Chinthu chosiyana kwambiri ndi chitukuko ndi chakuti chinthu chogwira ntchito si madzi omwe amasanduka mpweya, koma ndi maginito zitsulo. Chifukwa cha izi, kuchuluka kwa mphamvu zamagetsi kumawonjezeka ndi 30-40%.
Mtundu watsopano wa firiji unapangidwa ndi akatswiri a National Research Technological University "MISiS", omwe adagwirizana ndi anzake a ku Tver State University. Maziko a chitukuko choperekedwa ndi dongosolo lolimba la maginito, lomwe ponena za mphamvu zowonjezera mphamvu ndi 30-40% kuposa makina a compressor a gasi omwe amagwiritsidwa ntchito mu firiji wamba. Popanga dongosolo latsopano, mphamvu ya magnetocaloric idagwiritsidwa ntchito, zomwe zimati pamene maginito, maginito amasintha kutentha kwake. Chimodzi mwazinthu zachitukuko ndikuti ochita kafukufuku adatha kukwaniritsa zotsatira za cascade. Mipiringidzo ya Gadolinium yokwera pa gudumu lapadera imazungulira mwachangu, chifukwa chake imagwera mumlengalenga.
Olemba ntchitoyo akuti ukadaulo womwe adagwiritsa ntchito wakhalapo kwa zaka pafupifupi 20, koma aka ndi nthawi yoyamba kuti mfundo ya cascade ikwaniritsidwe bwino. Makhazikitsidwe ofanana omwe adapangidwa kale sangathe kugwiritsidwa ntchito pozizirira mwamphamvu, chifukwa amatha kusunga kutentha kwina.
M'tsogolomu, okonzawo akufuna kupitiriza chitukuko cha teknoloji ya cascade, chifukwa chake akukonzekera kukulitsa kutentha kwa firiji. Ndizodabwitsa kuti kukula kwa ma laboratory sikudutsa masentimita 15. Akatswiri amakhulupirira kuti m'tsogolomu chipangizo chophatikizikachi chingagwiritsidwe ntchito popanga makina opangira mpweya wa magalimoto, makina oziziritsa a zipangizo za microprocessor, ndi zina zotero.
