Ungayikhetha njani ifriji ebandayo enzulu?

A ifriji enzuluibhekisa kwisikhenkcezisi esinobushushu obuphantsi kune-18°C, kwaye sinokufikelela nakwi--40°C~- 80°C. Eziqhelekileyo zingasetyenziselwa ukukhenkceza inyama, ngelixa ezo zinobushushu obuphantsi zisetyenziswa kwilebhu, kwi-vaccine nakwezinye izixhobo zenkqubo.

Isikhenkcezisi esiqhelekileyo sisetyenziselwa ukugcina ukutya kwaselwandle, esinobushushu obuphakathi kwe-18°C ukuya kwi-25°C. Sisebenza kakuhle ekufrijini kwaye sisebenzisa i-compressor esebenza kakhulu, ezinzileyo kakhulu ukusetyenziswa ixesha elide. Kwangaxeshanye, kwiinkalo ezininzi, umzekelo, imisebenzi yaso iyafana.

Imisebenzi eqhelekileyo ibandakanya inkqubo yokupholisa umoya, isibonisi sokulawula ubushushu bedijithali, kunye nokuhamba okulula. Oku kwanele ngokupheleleyo ekuqandiseni ukutya kwaye kunokwanelisa iimfuno ze-80% yeevenkile ezinkulu ezikwimarike.

Ngokuphathelele izinto zokwakha, ukuba ngumthengisi webhrendi ovela kwamanye amazwe, uninzi lwazo zisebenzisa izinto zentsimbi engatyiwayo ezikumgangatho ophezulu. Izinto ezifana neecompressor, ii-evaporators, kunye nee-condenser zonke zifanelekile kwaye zineziqinisekiso zokufaneleka ezipheleleyo kunye neziqinisekiso zenkonzo.

Ubushushu befriji efrijini enzulu neqandisiweyo yelabhoratri bunokufikelela kwi-40°C ukuya kwi-80°C. Isebenzisa icompressor eyenzelwe wena, inobushushu obuzinzileyo befriji, inazo zonke imisebenzi yefriji eqhelekileyo, kwaye ixhotyiswe ngenkqubo yokujonga ubushushu ekrelekrele kunye nomsebenzi wesilumkiso sokhuseleko. Ayinalo nje kuphela ulawulo lobushushu oluchanekileyo kunye namava amahle omsebenzisi kodwa ikwanalo nexabiso eliphezulu.

Kumazwe aphuhlileyo, amashumi ezigidi zeerandi atyalwa kwiimvavanyo minyaka le. Uninzi lwezixhobo zokumisa luvela kubangenisi. Ngenxa yokwahluka kwamaxabiso kunye nezinye izinto, kodwa okubaluleke ngakumbi, ngokwembono yemali, kwiindawo ezifana nezikolo, xa imali ingekho phezulu, ingathathwa njengokungenisa ezinye izixhobo ezingabizi kakhulu.

Ziziphi izinto ekufuneka ziqwalaselwe xa ukhetha ifriji?

Okokuqala, kufuneka kuqwalaselwe ixabiso. Kuyo nayiphi na inkampani okanye iqela, xa kungeniswa izixhobo zobuchwephesha zokukhenkceza, into yokuqala ekufuneka iqwalaselwe kukuba ingaba uhlahlo lwabiwo-mali lwanele na. Khetha izixhobo ezikwimarike ezihlangabezana neemeko zexabiso ngokwebhajethi. Ukuba ixabiso lomthengisi liphezulu kunelo leqela labasebenzisi ngokubanzi, kuya kuba nzima ukuthengisa. Ukuba ixabiso liphantsi kakhulu, alilungelanga imveliso nophuhliso lweshishini. Kakade ke, kubaluleke kakhulu ukuqonda uthelekiso lwamaxabiso emarike. Kukho umahluko wamaxabiso kwimimandla eyahlukeneyo efana neYurophu, iMelika, kunye neSouth Asia.

Okwesibini, inkonzo emva kokuthengisa ibaluleke kakhulu. Nezixhobo ezikumgangatho ophezulu nezisemgangathweni ophezulu zinokuba neengxaki zenkonzo, kubandakanya ukuphathwa kweempazamo, izikhokelo zokusetyenziswa, njl. Ezinye izixhobo zokukhenkceza kufuneka ziqeqeshwe ngaphambi kokuba zisetyenziswe. Ukuba azisetyenziswa ngobuchule, ziya kubangela umonakalo kwizixhobo. Inxalenye ebalulekileyo yokuthenga kukuqonda inkonzo yeshishini, ubungakanani balo behlabathi kunye nesalathisi sophawu.

Emva kokuqwalasela ezi zinto zimbini zibalulekileyo, kufuneka kugxilwe kumgangatho kunye nemisebenzi yesikhenkcezisi. Abathengi kunye nabavelisi kufuneka balawule ngokungqongqo umgangatho. Nangona iimpawu ezininzi zineziqinisekiso zokufaneleka ezipheleleyo, oko akuthethi ukuba izixhobo azinangxaki konke konke. Umzekelo, kusenokungabikho ngxaki kwinkqubo yokuvelisa kunye nokupakisha, kodwa iingxaki zinokubakho ngexesha lokuthuthwa. Kubathengi, kubaluleke kakhulu ukwenza umsebenzi wokwamkela ngokungqongqo.

Kakade ke, ukutyikitywa kwekhontrakthi ngamaqela omabini kufuneka kwenziwe ngononophelo. Kaloku, kukukhusela izilangazelelo zamaqela omabini. Nika ingqalelo kuzo zonke iinkcukacha, kuquka necandelo loxanduva, imisebenzi eneenkcukacha ezenziwe ngokwezifiso, njl.

Oku kungasentla kukuqokelelwa komxholo malunga neefriji kule ngxaki. Igxile kakhulu ekubalulekeni kokukhetha ngokwezifiso, ukuqonda iintlobo ezahlukeneyo, amaxabiso, kunye nababoneleli beefriji, kunye nokwenza umsebenzi olungileyo kwinkqubo yovavanyo.
