Ungakhetha kanjani ifriji ejulile - efrijini?

A ejulile - isiqandisiibhekisela efrijini elinezinga lokushisa elingaphansi kuka -18°C, futhi lingafinyelela ngisho ku -40°C~-80°C. Ezijwayelekile zingase zisetshenziselwe ukuqandisa inyama, kanti lezi ezinamazinga okushisa aphansi zisetshenziswa elabhorethri, umgomo kanye nezinye izinto zokusebenza zesistimu.

Iziqandisi zohlobo ezejwayelekile zisetshenziselwa ukugcina ukudla kwasolwandle, ngezinga lokushisa elisukela ku-18°C kuya ku-25°C. Isebenza kahle kakhulu esiqandisini futhi yamukela i-compressor yokusebenza ephezulu, ezinzile kakhulu ekusebenziseni isikhathi eside. Ngesikhathi esifanayo, ezicini eziningi, isibonelo, imisebenzi yayo ayifani.

Imisebenzi evamile ihlanganisa isistimu yokupholisa yomoya, isibonisi sokulawula izinga lokushisa kwedijithali, nokuhamba okulula. Lokhu kwanele ngokuphelele ekuqandiseni ukudla futhi kungahlangabezana nezidingo zama-80% enxanxathela yezitolo emakethe.

Ngokwezinto zokwakha, uma kungumhlinzeki womkhiqizo ongenisiwe, iningi labo lisebenzisa izinto ezisezingeni eliphakeme - ezingenasici - izinto zensimbi. Izingxenye ezinjengama-compressor, ama-evaporator, nama-condensers zonke zifanelekile futhi zinezitifiketi eziphelele zeziqu neziqinisekiso zesevisi.

Izinga lokushisa laselabhorethri ejulile – isiqandisi singafinyelela – 40°C kuya – 80°C. Isebenzisa i-compressor eyenziwe ngokwezifiso, inezinga lokushisa lesiqandisi elizinzile, inayo yonke imisebenzi yesiqandisi esivamile, futhi ifakwe uhlelo oluhlakaniphile lokulawula izinga lokushisa kanye nomsebenzi wokuxwayisa ngokuphepha. Ayigcini nje ngokulawula izinga lokushisa okunembile kanye nolwazi oluhle kakhulu lomsebenzisi kodwa futhi inenani eliphezulu uma kuqhathaniswa.

Emazweni athuthukile, amashumi ezigidi zamaRandi atshalwa ekuhloleni unyaka ngamunye. Iningi lamathuluzi okuqandisa avela kubangenisi. Ngenxa yomehluko wamanani nezinye izici, kodwa okubaluleke kakhulu, ngokombono wezimali, emikhakheni efana nezikole, lapho izimali zingekho phezulu, kungabhekwa ukungenisa impahla ethile engabizi.

Yiziphi izici okufanele zicatshangelwe lapho ukhetha ifriji?

Okokuqala, inani lentengo kufanele licatshangelwe. Kunoma iyiphi inkampani noma iqembu, lapho ungenisa imishini yesiqandisi echwepheshile, into yokuqala okufanele uyihlole ukuthi isabelomali sanele yini. Khetha okokusebenza emakethe okuhlangabezana nezimo zentengo ngokuya ngesabelomali. Uma intengo yomphakeli iphezulu kunaleyo yeqembu labasebenzisi abajwayelekile, kuzoba nzima ukuyithengisa. Uma intengo iphansi kakhulu, ayihambisani nokukhiqizwa nokuthuthukiswa kwebhizinisi. Yiqiniso, kubaluleke kakhulu ukuqonda ukuqhathaniswa kwentengo yemakethe. Kukhona umehluko wamanani ezifundeni ezahlukene ezifana neYurophu, iMelika, naseNingizimu Asia.

Okwesibili, umkhiqizo emva - isevisi yokuthengisa ibaluleke kakhulu. Ngisho nezisetshenziswa ezisezingeni eliphezulu kakhulu - zokugcina neziphezulu - zingaba nezinkinga zesevisi, okuhlanganisa iphutha - ukuphatha, imihlahlandlela yokusebenzisa, njll. Ezinye izisetshenziswa zokuqandisa zidinga ukuqeqeshwa ngaphambi kokusetshenziswa. Uma ingasetshenziswa ngobungcweti, izophinde idale umonakalo emishinini. Ingxenye ebalulekile yokuthenga ukuqonda insiza yebhizinisi, isikali sayo somhlaba wonke kanye nenkomba yomkhiqizo.

Ngemva kokucabangela lezi zici ezimbili ezibalulekile, ikhwalithi nemisebenzi yesiqandisi kudingeka kugxilwe kukho. Kokubili abathengi nabakhiqizi kufanele balawule ikhwalithi ngokuqinile. Nakuba izinhlobo eziningi zinezitifiketi zemfundo eziphelele, akusho ukuthi okokusebenza akunazinkinga nhlobo. Isibonelo, kungase kungabi nezinkinga ohlelweni lokukhiqiza nokupakisha, kodwa izinkinga zingase zenzeke ngesikhathi sokuthutha. Kubathengi, kubaluleke kakhulu ukwenza umsebenzi oqinile wokwamukela.

Yebo, ukusayinwa kwenkontileka yizo zombili izinhlangothi nakho kudinga ukwenziwa ngokucophelela. Phela, iwukuvikela izithakazelo zezinhlangothi zombili. Naka yonke imininingwane, okuhlanganisa ukuhlukaniswa kwesikweletu, imisebenzi enemininingwane eyenziwe ngokwezifiso, njll.

Okungenhla ukuqoqwa kokuqukethwe mayelana namafriji kulo magazini. Igxila kakhulu ekubalukeni kokukhetha ukwenza ngokwezifiso, ukuqonda izinhlobo ezahlukene, amanani, nabahlinzeki bamafriji, kanye nokwenza umsebenzi omuhle enqubweni yokuhlola.
