Ezindaweni zezentengiselwano, amafriji eziphuzo ayimishini ebalulekile yokugcina nokubonisa iziphuzo ezahlukahlukene. Njengengxenye ebalulekile yamafriji, amandla eshelufu okuthwala umthwalo ahlobene ngqo nokusebenza kahle nokuphepha kokusetshenziswa kwefriji.
Ngokombono wobukhulu, ubukhulu beshelufu buyisici esibalulekile esithinta amandla alo okuthwala umthwalo. Ngokuvamile, ubukhulu bamashidi ensimbi asetshenziselwa amashalofu efriji yeziphuzo busukela kumamilimitha ayi-1.0 kuya kwangu-2.0. Kukhona ubudlelwano obuhle phakathi kobukhulu bezinto zensimbi kanye namandla alo okuthwala umthwalo; ishidi elijiyile lisho ukumelana okunamandla nokugoba kanye nokuguquka. Lapho ubukhulu beshelufu bufika kumamilimitha ayi-1.5 noma ngaphezulu, bunganciphisa ngempumelelo izinga lokugoba okubangelwa amandla adonsela phansi lapho uthwala isisindo esithile seziphuzo, kunikeze isisekelo esiqinile sesakhiwo sokuthwala umthwalo. Isibonelo, lapho ubeka amabhodlela amaningi amakhulu eziphuzo ezine-carbonated, ishelufu elijiyile lingahlala lizinzile ngaphandle kokucwila noma ukuguquka okusobala, ngaleyo ndlela kuqinisekiswe ukugcinwa okuphephile nokuboniswa kweziphuzo.
Ngokuphathelene nezinto zokwakha, amashalofu efriji yeziphuzo avame ukwenziwa ngensimbi engagqwali noma insimbi egoqekile ebandayo yekhwalithi ephezulu. Insimbi engagqwali inamandla amahle kakhulu, ukumelana nokugqwala, kanye nokuqina. Ayikwazi nje kuphela ukuthwala ingcindezi enkulu kodwa futhi ingasetshenziswa isikhathi eside endaweni efudumele yefriji ngaphandle kokugqwala noma ukulimala, okuqinisekisa ukuqina kwesakhiwo seshelufu futhi ngaleyo ndlela ithuthukise amandla okuthwala umthwalo. Ngemva kokucubungula i-cold-rolling, insimbi egoqekile ebandayo ikhulisile ubuningi bezinto zokwakha kanye nobunzima, futhi amandla ayo nawo akhuliswa kakhulu, okungaphinde kunikeze ukusebenza okuhle kokuthwala umthwalo eshelufini. Uma sithatha ishelufu lensimbi engagqwali njengesibonelo, izakhiwo zalo zezinto zokwakha ziyenza ikwazi ukuphatha kalula umthwalo weshelufu eligcwele leziphuzo ezisemathinini ngaphandle kokulimala eshelufini ngenxa yamandla anele ezinto zokwakha.
Uma sibheka ubukhulu beshelufu, okuhlanganisa ubude, ububanzi, nokuphakama, kuhlobene kakhulu nomthamo walo wokuthwala umthwalo. Ishelufu elikhulu linendawo enkulu yokuthwala amandla yesakhiwo salo sokusekela. Uma ubude nobubanzi beshelufu bukhulu, uma buklanywe ngokufanele, isisindo esisatshalaliswa eshelufini singadluliselwa ngokulinganayo kuhlaka oluphelele lwefriji, okuvumela ukuthi lithwale izinto eziningi. Isibonelo, amashalofu ezinye iziqandisi ezinkulu zeziphuzo angaba ngaphezu kwemitha eli-1 ubude kanye namashumi amaningana amasentimitha ububanzi. Ubukhulu obunjalo bubenza bakwazi ukubamba amashumi noma amakhulu amabhodlela eziphuzo anezincazelo ezahlukene, okuhlangabezana ngokugcwele nezidingo zezindawo zezentengiselwano zokugcina inani elikhulu leziphuzo. Ngesikhathi esifanayo, ukwakheka kokuphakama kweshelufu nakho kuthinta umthamo walo wokuthwala umthwalo; ukuphakama okufanele kungaqinisekisa ibhalansi yamandla eshelufu ohlangothini oluqondile, kuthuthukise kakhulu umthamo wokuthwala umthwalo.
Ngaphezu kwalezi zici ezingenhla, ukwakheka kweshelufu akunakunganakwa. Isakhiwo esifanelekile, njengokuhlelwa kwezimbambo zokuqinisa kanye nokusatshalaliswa kwamaphuzu okusekela, kungathuthukisa kakhulu ukusebenza kweshelufu okuthwala umthwalo. Izimbambo zokuqinisa zingasakaza isisindo ngempumelelo futhi zinciphise ukuguquka kweshelufu; amaphuzu okusekela asakazwe ngokulinganayo angenza amandla eshelufu alingane kakhudlwana futhi agweme ukugcwala kwendawo.
Ngamafuphi, amandla okuthwala umthwalo wamashalofu efriji yeziphuzo awumphumela womphumela ohlangene wezinto eziningi ezifana nobukhulu, izinto zokwakha, usayizi, kanye nomklamo wesakhiwo. Ngokuvamile, amashalofu efriji yeziphuzo asezingeni eliphezulu, anobukhulu obufanele (amamilimitha angu-1.5 noma ngaphezulu), enziwe ngensimbi engagqwali noma insimbi egoqekile esezingeni eliphezulu, futhi enosayizi ofanele kanye nomklamo wesakhiwo, angaba namandla okuthwala umthwalo angamakhilogremu angamashumi amaningana. Angahlangabezana nezidingo zokuthwala umthwalo zezindawo zezentengiselwano zokugcina nokubonisa iziphuzo ezahlukahlukene, anikeze iziqinisekiso eziqinile zokugcina okuphephile kanye nokuboniswa kweziphuzo okuphumelelayo.
