Konkeamafriji ekhemisi, amafriji okugomafuthiamafriji aselabhorethriaklanyelwe izinjongo ezikhethekile ngokuhambisana nemithetho yezemithi neyezokwelapha, ngenxa yezinto eziningi zebanga lezokwelapha ezithambile futhi izinhlobo ezingezwani nokushisa, lawa mafriji kufanele akwazi ukulawula amazinga okushisa ngokunemba nangesimo esingaguquki.Amazinga okushisa anembile amafriji ethu ekhemisi alawulwa yi-microprocessor ebangeni elingu-2°C no-8°C, futhi agadwa inzwa ye-thermistor ukuze kuqinisekiswe ukuthi zonke izinto ezisetshenziswayo ozigcinayo zihlala emazingeni okushisa asezingeni eliphezulu futhi ezimweni ezingaguquki, ngakho lezi amafriji ayindlela ekahle yokugcina imithi, imigomo, nama-specimens, anganikezi nje kuphela ngokuphelele nangobuchwepheshe.izixazululo zefrijiezibhedlela kanye nemithi, kodwa futhi inikeza ukuzinza nokwethembeka ukuze kuhlangatshezwane nezidingo zokugcina neziqandisi zelabhorethri kanye nesinye isigaba socwaningo.Kwa-Newell, nalu uhla olubanzi lokukhetha ukuhlangabezana nezidingo eziningi ezihlukene zomthamo nokusebenza, ngaphezu kwamamodeli ethu avamile, siphinde senze ngendlela oyifisayo.isiqandisi sezokwelaphaimikhiqizo ukuhlinzekela izidingo zakho ezikhethekile.
