Ngamnye wethu unefriji ekhaya. Kunzima ukucinga ukuba iminyaka engama-80 edlulileyo le mishini yasendlini yayingasungulwa. Kodwa akusiyo wonke umntu ocinga ngecebo kunye nomgaqo weqrijini. Kodwa lo mzuzu othakazelisayo kunye nolwazi: ulwazi malunga nendlela i-friji yakho isebenza ngayo, inokuhlala ihamba kakuhle xa kukho nayiphi na ingxaki okanye ukuphazamiseka, kwaye unokunceda ukhethe umzekelo omhle xa uthengi.
Usebenza njani umfriji?
Umsebenzi wefriji yomzimba oqhelekileyo usekelwe kwisenzo sefriji (ngokuqhelekileyo i-freon). Le nkunkuma yegesi ihamba kunye neesekethe ezivaliweyo, iguqula ubushushu bayo. Emva kokufikelela kwindawo yokubilisa (kunye ne-freon ivela -30 ukuya ku--150 ° C), ikhuphuka kwaye ithathe ubushushu kwiindonga ze-evaporator. Ngenxa yoko, ukushisa ngaphakathi kwegumbi kuncitshiswe kuye kumlinganiselo we-6 ° C.
Amacandelo efriji ayincediswa yizo ziqhamo zefriji njenge-compressor (idala uxinzelelo olufunwayo), i-evaporator (ithatha ubushushu ngaphakathi ngaphakathi kwigumbi lokuqhumisa), i-condenser (idlulisa ubushushu kummandla) kunye nemingxuma yokuphosa (i-valve therminggulation kunye ne-capillary).
Ngokwahlukileyo, kufuneka kuthiwe ngomgaqo we-compressor compressor. Yenzelwe ukulawula ukunyanzelwa kwengcinezelo kwinkqubo. I-compressor igxininisa i-friji ye-evaporated, igxininise kwaye iphinde iphinde iphinde iphinde iphinde iphinde ikhuphe kwi-condenser. Kule meko, ukushisa kwe-freon kuphakama, kwaye kwakhona kuya kuba ngumbane. Icompressor yefriji isebenza ngenxa yemoto yombane, ekhoyo ngaphakathi kwezindlu zayo. Njengomgaqo, i-piston compressors ifakwe kwiifriji.
Ngaloo ndlela, umgaqo wokusebenza wefriji unokuchazwa ngokufutshane njengenkqubo yokuvuselela ukushisa kwangaphakathi kwindalo, ngenxa yoko umoya ophepheni. Le nkqubo ibizwa ngokuba yi "Carnot cycle". Siyabulela kuye ukuba iimveliso esizigcina kwifriji ixesha elide aziyi kuhlahloka ngenxa yokushisa okuphantsi rhoqo.
Kwakhona kufuneka kuqatshelwe ukuba kwiindawo ezahlukeneyo zeqribri ukushisa kuyahluka, kwaye le nyaniso ingasetyenziselwa ukugcina iimveliso ezahlukeneyo. Kwiziqhamo zangoku ezibizayo ezinjenge-Side-by-Side kukho ukwahlula okucacileyo kwiindawo: kuyisebe eliqhelekileyo lefriji, "i-zero zone" (biofresh) inyama, intlanzi, i-cheeses, i-sausages kunye nemifuno, i-efriji kunye nendawo ebizwa ngokuba yi-super-frost zone. Okukugqibela kubonakaliswe ngokukhawuleza (emva kwemizuzu embalwa) iphosa umkhiqizo -36 ° C. Ngenxa yoko, i-crystalline lattice yemeko ehluke ngokusemthethweni yenziwa, ngelixa ezinye izinto ezinomsebenzi zigcinwa kunokuba ziqhelaniswe.
Isifriji sisebenza njani?
Iifriji ngeenkqubo ezingenamsebenzi weqhwa zisebenza kumgaqo ofanayo, kodwa ulwahlulo oluthile lukhona kwiinkqubo ezihlaselayo. Iifriji zasemakhaya eziqhelekileyo kunye ne-drop-type type evaporator kufuneka zihlaziywe ngezikhathi ezithile, ukuze iqhwa, eliye lahlala eludongeni legumbi, aliphazamisi ukuqhutyelwa phambili kweyunithi.
Awunakukhathazeka malunga nale nto ifriji yakho ifakwe kwindlela yokwazi. Ngenxa yenkqubo eqhubekayo yokujikeleza umoya obandayo ngaphakathi ekamelweni, umswakama, ohlala phezu kweendonga, ugxobhoza aze anxweme epanini, apho iphinda iphinde iphele.
Iifriji ziyazi ukuba iqhwala zixhobo zezizukulwana ezitsha, ezisebenzisekayo ngakumbi, kunemodeli endala kunye nenkqubo yokulahla. Abanamandla kakhulu, kwaye ukupholisa kweemveliso kuzo kubonakala ngokugqithiseleyo. Nangona kunjalo, nabo banemiphumo yabo, ngokusekelwe kumgaqo womsebenzi uchazwe ngasentla. Ngenxa yokuba igumbi lihlala lijikeleza umoya, kuthatha umswakama ngaphandle kokutya, ekugqibeleni kumile. Ngoko ke, kwiimveliso zeqabunga kufuneka zigcinwe kuphela kwizikhuni ezivaliweyo.
Ngoku, ukwazi indlela yokusebenzisa isiqabetho, awuyi kuba neengxaki ngokukhetha nokuthenga iyunithi entsha kunye nokusebenza kwayo.
