Ungayikhetha kanjani ifriji ebandayo ejulile?

A ifriji ejulileibhekisela efrijini elinezinga lokushisa elingaphansi kuka-18°C, futhi lingafinyelela ngisho naku-40°C~- 80°C. Ezivamile zingasetshenziswa ukuqandisa inyama, kanti lezo ezinamazinga okushisa aphansi zisetshenziswa elabhorethri, emithi yokugoma kanye neminye imishini yesistimu.

Ifriji yohlobo olujwayelekile isetshenziselwa ukugcina ukudla kwasolwandle, enezinga lokushisa eliphakathi kuka-18°C kuya ku-25°C. Isebenza kahle kakhulu ekuqandiseni futhi isebenzisa i-compressor esebenza kahle kakhulu, ezinzile kakhulu ukusetshenziswa isikhathi eside. Ngesikhathi esifanayo, ezicini eziningi, isibonelo, imisebenzi yayo iyodwa.

Imisebenzi ejwayelekile ifaka phakathi uhlelo lokupholisa umoya, isibonisi sokulawula izinga lokushisa sedijithali, kanye nokuhamba okulula. Lokhu kwanele ngokuphelele ekuqandiseni ukudla futhi kungahlangabezana nezidingo zama-80% ezitolo ezinkulu emakethe.

Ngokuphathelene nezinto zokwakha, uma kungumhlinzeki womkhiqizo ongenisiwe, iningi lawo lisebenzisa izinto zensimbi engagqwali ezisezingeni eliphezulu. Izingxenye ezifana nama-compressor, ama-evaporator, nama-condenser zonke ziyafaneleka futhi zinezitifiketi zokufaneleka eziphelele kanye neziqinisekiso zesevisi.

Izinga lokushisa le-laboratory deep – freezer lingafinyelela ku-40°C kuya ku-80°C. Lisebenzisa i-compressor eyenziwe ngokwezifiso, linokushisa okuzinzile kwe-friji, linayo yonke imisebenzi ye-freezer evamile, futhi lifakwe uhlelo lokuqapha lokushisa oluhlakaniphile lochwepheshe kanye nomsebenzi wokuxwayisa ngokuphepha. Aligcini nje ngokulawula izinga lokushisa okunembile kanye nokuhlangenwe nakho okuhle kakhulu komsebenzisi kodwa futhi linentengo ephezulu.

Emazweni athuthukile, amashumi ezigidi zamaRandi atshalwa ezivivinyweni minyaka yonke. Iningi lamathuluzi okuqandisa livela kubangenisi. Ngenxa yokwehluka kwamanani nezinye izici, kodwa okubaluleke kakhulu, ngokombono wezimali, emikhakheni efana nezikole, lapho imali ingekho phezulu, kungacatshangwa ukuthi kungeniswa imishini ethile engabizi.

Yiziphi izinto okufanele uzicabangele lapho ukhetha ifriji?

Okokuqala, kufanele kucatshangelwe isici sentengo. Kunoma yiliphi ibhizinisi noma iqembu, lapho ungenisa imishini yokuqandisa yobungcweti, into yokuqala okufanele uyihlole ukuthi isabelomali sanele yini. Khetha imishini emakethe ehlangabezana nezimo zentengo ngokwesabelomali. Uma intengo yomhlinzeki iphakeme kuneyeqembu labasebenzisi abajwayelekile, kuzoba nzima ukuyithengisa. Uma intengo iphansi kakhulu, ayivumeli ukukhiqizwa kanye nentuthuko yebhizinisi. Yiqiniso, kubaluleke kakhulu ukuqonda ukuqhathaniswa kwentengo yemakethe. Kukhona umehluko wentengo ezindaweni ezahlukene njengeYurophu, iMelika, kanye neNingizimu Asia.

Okwesibili, isevisi yokuthengisa ngemuva komkhiqizo ibaluleke kakhulu. Ngisho nemishini esezingeni eliphezulu kakhulu nesezingeni eliphezulu ingaba nezinkinga zesevisi, okuhlanganisa ukuphathwa kwamaphutha, iziqondiso zokusetshenziswa, njll. Eminye imishini yokuqandisa idinga ukuqeqeshwa ngaphambi kokusetshenziswa. Uma ingasetshenziswa ngobuchwepheshe, izolimaza nemishini. Ingxenye ebalulekile yokuthenga ukuqonda isevisi yebhizinisi, ubukhulu bayo bomhlaba wonke kanye nenkomba yomkhiqizo.

Ngemva kokucabangela lezi zici ezimbili ezibalulekile, ikhwalithi nemisebenzi yesiqandisi kudingeka kugxilwe kuso. Bobabili abathengi nabakhiqizi kufanele balawule ngokuqinile ikhwalithi. Nakuba izinhlobo eziningi zinezitifiketi zokufaneleka eziphelele, akusho ukuthi imishini ayinazo nhlobo izinkinga. Isibonelo, kungase kungabi nezinkinga enqubweni yokukhiqiza nokupakisha, kodwa kungase kube nezinkinga ngesikhathi sokuthuthwa. Kubathengi, kubaluleke kakhulu ukwenza umsebenzi wokwamukela oqinile.

Vele, ukusayinwa kwenkontileka yizinhlangothi zombili nakho kudingeka kwenziwe ngokucophelela. Phela, kuwukuvikela izintshisekelo zazo zombili izinhlangothi. Naka yonke imininingwane, okuhlanganisa nesigaba sesibopho, imisebenzi eningiliziwe eyenziwe ngokwezifiso, njll.

Lokhu okungenhla ukuqoqwa kokuqukethwe mayelana namafriji kule nkinga. Kugxile kakhulu ekubalulekeni kokukhetha ngokwezifiso, ukuqonda izinhlobo ezahlukene, amanani, kanye nabaphakeli bamafriji, kanye nokwenza umsebenzi omuhle enqubweni yokuhlola.
