Ngamunye wethu unefriji ekhaya. Kunzima ukucabanga ukuthi eminyakeni engaba ngu-80 edlule le mishini yasendlini ayizange isungulwe okwamanje. Kodwa akubona wonke umuntu ocabanga ngedivayisi kanye nesimiso sesiqandisini. Kodwa lokhu kuyisikhathi esithakazelisayo kakhulu nesifundisayo: ulwazi lokuthi i-friji yakho isebenza kanjani, ingahlala ihamba kahle uma kunoma yikuphi ukukhubazeka noma ukuphazamiseka, futhi kusiza ukukhetha imodeli emihle uma uthenga.
Umshini wesiqandisini usebenza kanjani?
Umsebenzi wefriji yomkhaya evamile usekelwe esenzweni sefriji (ngokuvamile kuvamile). Leli gesi elimnandi lihamba ngesifunda esivaliwe, lishintsha izinga lokushisa kwalo. Sekufinyelele endaweni yokubilisa (futhi i-freon ivela ku -30 kuya ku--150 ° C), ikhuphuka futhi isuse ukushisa kusuka ezindongeni ze-evaporator. Ngenxa yalokho, izinga lokushisa ngaphakathi ekamelweni linciphisa libe ngu-6 ° C.
Izakhi ze-frijiza zisiza lezo zakhi zeqandisini njenge-compressor (yakha ingcindezi efunayo), i-evaporator (ithatha ukushisa ngaphakathi ngaphakathi egumbini eliqandisayo), i-condenser (idlulisa ukushisa emvelweni) kanye nezimbobo eziphoqa (i-valve thermoregulation ne-capillary).
Ngokuhlukile, kufanele kuthiwe ngesimiso se-compressor compressor. Yenzelwe ukulawula ukucindezela kwehla ohlelweni. I-compressor igcizelela i-refrigerant ephukile, iyayiqeda futhi iphinde iphinde iphinde iphinde iphinde iphinde ihambisane ne-condenser. Kulesi simo, ukushisa kwe-freon kuphakama, futhi kuphinda kube yi-liquid. I-compressor yesiqandisini isebenza ngenxa yemoto kagesi, etholakala ngaphakathi kwezindlu zayo. Njengomthetho, ama-piston compressors afakwe uphawu ezifrijini.
Ngakho-ke, isimiso sokusebenza sesiqandisini singachazwa ngokufishane njengendlela yokuvuselela ukushisa kwangaphakathi emvelweni, ngenxa yalokho umoya ekamelweni ugoba. Le nqubo ibizwa ngokuthi "umjikelezo we-Carnot". Kungenxa yakhe ukuthi imikhiqizo esigcina esiqandisini isikhathi eside ayihloli ngenxa yokushisa okuphansi okugcinwe njalo.
Futhi kufanele kuqashelwe ukuthi ezindaweni ezahlukene eziqandisini izinga lokushisa lihlukile, futhi leli qiniso lingasetshenziswa ukugcina imikhiqizo ehlukene. Eziqandisini zanamuhla eziqashisayo ezinjenge-Side-by-Side kukhona ukuhlukaniswa okucacile kube yizingxenye: kuyiminyango evamile yesibhakabhaka, "i-zero zone" (i-biofresh) yenyama, inhlanzi, i-cheeses, ama-sausages nemifino, ifriji kanye nendawo okuthiwa yi-super-frost. Lesi sigaba sibonakala ngokusheshisa kakhulu (kungakapheli imizuzwana embalwa) sishaye umkhiqizo ku -36 ° C. Ngenxa yalokho, i-crystalline lattice yomumo ohlukile ngokweqile yenziwa, kuyilapho ezinye izinto eziwusizo zigcinwa kunezingqimba ezijwayelekile.
Isiqandisini sisebenza kanjani?
Amafriji ane-no-frost system isebenza ngesimiso esifanayo, kodwa umehluko othize ukhona ezinkambisweni zokuhlukunyezwa. Amafriji ejwayelekile angasesekhaya ama-evaporator kumele ahlelwe njalo, ukuze iqhwa, eliye lahlelwa odongeni lwekamelo, aliphazamisi ukusebenza okuqhubekayo kweyunithi.
Asikho isidingo sokukhathazeka ngalokhu uma ifriji yakho ifakwe uhlelo lokukwazi. Ngenxa yenqubo eqhubekayo yokuhambisa umoya obandayo ngaphakathi ekamelweni, umswakama, ohlala ezindongeni, uphahla futhi uphume epanini, lapho uphinde uphume khona.
Amafriji ayazi amaqhwa amadivaysi esizukulwane esisha, elula kakhulu ukusetshenziswa, kunamamodeli endala anehlelo lokudonsa. Ayanamandla kakhulu, futhi ukupholisa kwemikhiqizo kuzo kuvela ngokulinganayo. Kodwa-ke, nabo banamaphutha abo, ngokusekelwe esimisweni somsebenzi esichazwe ngenhla. Ngenxa yokuthi ikamelo lihlala lijikeleza umoya, kuthatha umswakama ngaphandle kokudla, okugcina kumile. Ngakho-ke, kwimikhiqizo ye-frost kufanele igcinwe kuphela ezigodini ezivaliwe.
Manje, ukwazi ukuthi ungasebenzisa kanjani isiqandisini, ngeke ube nezinkinga ngokukhetha nokuthenga i-unit entsha nokusebenza kwayo.
