Kwiindawo zorhwebo, iifriji zesiselo zizixhobo ezibalulekileyo zokugcina nokubonisa iziselo ezahlukeneyo. Njengenxalenye ebalulekileyo yeefriji, umthamo weshelufu wokuthwala umthwalo unxulumene ngokuthe ngqo nokusebenza kakuhle kunye nokhuseleko lokusetyenziswa kwefriji.
Ngokwembono yobukhulu, ubukhulu beshelufu yinto ebalulekileyo echaphazela amandla ayo okuthwala umthwalo. Ngokubanzi, ubukhulu beeshiti zesinyithi ezisetyenziselwa iishelufu zefriji yesiselo buqala kwi-1.0 ukuya kwi-2.0 millimeters. Kukho ulwalamano oluhle phakathi kobukhulu bezinto zesinyithi kunye nobukhulu bazo bokuthwala umthwalo; ishiti elityebileyo lithetha ukumelana okunamandla nokugoba kunye nokuguquka. Xa ubukhulu beshelufu bufikelela kwi-1.5 millimeters nangaphezulu, bunokunciphisa ngempumelelo izinga lokugoba okubangelwa ngamandla omxhuzulane xa uthwele ubunzima obuthile beziselo, bubonelele ngesiseko esiqinileyo sokuthwala umthwalo. Umzekelo, xa ubeka iibhotile ezininzi ezinkulu zeziselo ezinekhabhoni, ishelufu etyebileyo inokuhlala izinzile ngaphandle kokucwila okanye ukuguqulwa okubonakalayo, ngaloo ndlela iqinisekisa ukugcinwa okukhuselekileyo kunye nokuboniswa kweziselo.
Ngokuphathelele izinto zokwakha, iishelufu zefriji yesiselo zihlala zenziwe ngentsimbi engagqwaliyo okanye intsimbi eqengqelekayo ekumgangatho ophezulu. Intsimbi engagqwaliyo inamandla amahle kakhulu, iyamelana nokugqwala, kwaye ihlala ixesha elide. Ayinakuthwala kuphela uxinzelelo olukhulu kodwa ingasetyenziswa ixesha elide kwindawo efumileyo yefriji ngaphandle kokugqwala okanye ukonakala, iqinisekisa uzinzo lwesakhiwo seshelufu kwaye ngaloo ndlela iphucula amandla okuthwala umthwalo. Emva kokulungiswa kwe-cold-rolling, intsimbi eqengqelekayo ebandayo inobuninzi bezinto kunye nobunzima, kwaye amandla ayo ayanda kakhulu, nto leyo enokubonelela ngokusebenza okuhle kokuthwala umthwalo kwishelufu. Ukuthatha ishelufu yentsimbi engagqwaliyo njengomzekelo, iimpawu zayo zezinto ziyenza ikwazi ukuphatha ngokulula umthwalo weshelufu epheleleyo yeziselo ezisemathinini ngaphandle kokonakala kwishelufu ngenxa yamandla angonelanga ezinto zokwakha.
Ukujonga ubukhulu, ubukhulu beshelufu, kuquka ubude, ububanzi, kunye nokuphakama, bunxulumene kakhulu nomthamo wayo wokuthwala umthwalo. Ishelufu enkulu inendawo enkulu yokuthwala amandla kwisakhiwo sayo sokuxhasa. Xa ubude nobubanzi beshelufu bukhulu, ukuba benziwe ngokufanelekileyo, ubunzima obusasazwa kwishelufu bunokudluliselwa ngokulinganayo kwisakhelo iyonke sefriji, nto leyo evumela ukuba ithwale izinto ezininzi. Umzekelo, iishelufu zezinye iifriji ezinkulu zesiselo zingaba ngaphezu kwemitha e-1 ubude kunye namashumi eesentimitha ububanzi. Ubukhulu obunjalo bubenza bakwazi ukubamba amashumi okanye amakhulu eebhotile zeziselo zeenkcukacha ezahlukeneyo, nto leyo ehlangabezana ngokupheleleyo neemfuno zeendawo zorhwebo zokugcina inani elikhulu leziselo. Kwangaxeshanye, uyilo lokuphakama kweshelufu luchaphazela nomthamo wayo wokuthwala umthwalo; ukuphakama okufanelekileyo kunokuqinisekisa ibhalansi yamandla yeshelufu kwicala elithe nkqo, ukuphucula ngakumbi umthamo wokuthwala umthwalo iyonke.
Ukongeza kwezi zinto zingasentla, uyilo lwesakhiwo seshelufu alunakuze lutyeshelwe. Ulwakhiwo olufanelekileyo, olufana nolungiselelo lweembambo zokuqinisa kunye nokusasazwa kweendawo zokuxhasa, lunokuphucula ngakumbi ukusebenza kweshelufu ekuthwaleni umthwalo. Iimbambo zokuqinisa zinokusasaza ubunzima ngempumelelo kwaye zinciphise ukuguquka kweshelufu; iindawo zokuxhasa ezisasazwe ngokulinganayo zinokwenza amandla eshelufu alungelelaniswe ngakumbi kwaye kuthintelwe ukuxinana kwendawo.
Ngamafutshane, amandla okuthwala umthwalo weeshelufu zefriji yesiselo sisiphumo sesiphumo esidibeneyo sezinto ezininzi ezifana nobukhulu, izinto, ubungakanani, kunye noyilo lwesakhiwo. Ngokubanzi, iishelufu zefriji yesiselo ezikumgangatho ophezulu, ezinobukhulu obufanelekileyo (iimilimitha ezili-1.5 nangaphezulu), ezenziwe ngentsimbi engatyiwayo okanye intsimbi eqengqelekayo ekumgangatho ophezulu, kwaye enobukhulu obufanelekileyo kunye noyilo lwesakhiwo, zinokuba nomthamo wokuthwala umthwalo weekhilogram ezilishumi. Zinokuhlangabezana neemfuno zokuthwala umthwalo kwiindawo zorhwebo zokugcina nokubonisa iziselo ezahlukeneyo, zibonelela ngeziqinisekiso eziqinileyo zokugcina ngokukhuselekileyo kunye nokuboniswa ngokufanelekileyo kweziselo.
