Umehluko wokushisa kokupholisa kwamafriji amancane ezentengiselwano ubonakala njengongahlangabezani nezindinganiso. Ikhasimende lidinga izinga lokushisa elingu-2 ~ 8℃, kodwa izinga lokushisa langempela lingu-13 ~ 16℃. Isixazululo esijwayelekile ukucela umenzi ukuthi ashintshe ukupholisa komoya kusuka kumsele womoya owodwa kuya kumsele womoya ophindwe kabili, kodwa umenzi akanazo izimo ezinjalo. Enye inketho ukufaka esikhundleni se-compressor nge-compressor enamandla aphezulu, okuzokhulisa intengo, futhi ikhasimende lingase lingakwazi ukuyikhokhela. Ngaphansi kwemingcele emibili yemikhawulo yobuchwepheshe kanye nokuzwela izindleko, kubalulekile ukuqala ngokusebenzisa ukusebenza okungenzeka kwemishini ekhona kanye nokwenza ngcono ukusebenza ukuze kutholakale ikhambi elingahlangabezana nesidingo sokupholisa futhi livumelane nesabelomali.
1. Ukuthuthukisa ukuphambuka kwepayipi lomoya
Umklamo wepayipi lomoya elilodwa unendlela eyodwa, okuholela ekushintsheni kokushisa okusobala ngaphakathi kwekhabhinethi. Uma kungekho lwazi ekwakhiweni kwepayipi lomoya elikabili, umphumela ofanayo ungatholakala ngokulungiswa okungekona okwesakhiwo. Ngokukhethekile, okokuqala, engeza ingxenye yokuphambukisa engasuswa ngaphakathi kwepayipi lomoya ngaphandle kokushintsha isakhiwo somzimba sepayipi lomoya lokuqala.
Okwesibili, faka i-splitter enobunjwa buka-Y endaweni yokukhipha umoya ye-evaporator ukuze uhlukanise ukugeleza komoya okukodwa kube yimifudlana emibili ephezulu nengezansi: eyodwa igcina indlela yokuqala iqonde ngqo kungqimba oluphakathi, kanti enye iqondiswa esikhaleni esiphezulu nge-deflector ethambekele ku-30°. I-engeli yefoloko ye-splitter ihlolwe nge-fluid dynamics simulation ukuqinisekisa ukuthi isilinganiso sokugeleza kwemifudlana emibili yomoya singu-6:4, okungagcini nje ngokuqinisekisa ukuqina kokupholisa endaweni eyinhloko yengqimba ephakathi kodwa futhi kugcwalisa indawo eyimpumputhe engu-5cm ephezulu epholile phezulu. Ngesikhathi esifanayo, faka ipuleti lokubonisa elinobunjwa obufana ne-arc phansi kwekhabhinethi. Usebenzisa izici zokucwila komoya obandayo, umoya obandayo oqongelelwe ngokwemvelo phansi ubonakala emakhoneni aphezulu ukuze wakhe ukujikeleza kwesibili.
Ekugcineni, faka i-splitter, uhlole umphumela, bese ubheka ukuthi izinga lokushisa lifinyelela ku-2 ~ 8℃. Uma kungafinyelelwa, kuzoba yisisombululo esihle kakhulu ngezindleko eziphansi kakhulu.
2. Ukufakwa esikhundleni kwesiqandisi
Uma izinga lokushisa lingehli, phinda ufake i-refrigerant (ugcine imodeli yokuqala ingashintshiwe) ukuze wehlise izinga lokushisa lokuhwamuka libe yi--8℃. Lokhu kulungiswa kwandisa umehluko wokushisa phakathi kwe-evaporator nomoya ekhabetheni ngo-3℃, kuthuthukise ukusebenza kahle kokushintshana kokushisa ngo-22%. Buyisela ithubhu ye-capillary ehambisanayo (khuphula ububanzi bangaphakathi kusuka ku-0.6mm kuya ku-0.7mm) ukuqinisekisa ukuthi ukugeleza kwe-refrigerant kuvumelana nokushisa okusha kokuhwamuka futhi ugweme ingozi yesando soketshezi lwe-compressor.
Kufanele kuqashelwe ukuthi ukulungiswa kwezinga lokushisa kudinga ukuhlanganiswa nokwenza ngcono okunembile kwe-logic yokulawula izinga lokushisa. Shintsha i-thermostat yokuqala yemishini nge-module yokulawula izinga lokushisa kagesi bese usetha indlela yokuqalisa ekabili: lapho izinga lokushisa eliphakathi kwikhabhinethi lidlula u-8℃, i-compressor iphoqeleka ukuqala; lokhu akugcini nje ngokuqinisekisa umphumela wokupholisa kodwa futhi kugcina ukusebenza kahle kokupholisa kusesimweni esihle kakhulu.
3.Ukunciphisa ukuphazamiseka komthombo wokushisa wangaphandle
Ukushisa okweqile ekhabhinethi kuvame ukuba umphumela wokungalingani phakathi komthwalo wemvelo kanye nomthamo wokupholisa. Uma amandla okupholisa engakwazi ukukhushulwa, ukunciphisa umthwalo wemvelo wemishini kunganciphisa ngokungaqondile igebe phakathi kokushisa kwangempela kanye nenani eliqondiwe. Endaweni eyinkimbinkimbi yezindawo zezentengiselwano, ukuzivumelanisa nezimo nokuguqulwa kudingeka kwenziwe kusuka ezilinganisweni ezintathu.
Okokuqala ukuqinisa ukuvikelwa kokushisa kwekhabhinethi. Faka iphaneli yokushisa ye-vacuum engu-2mm ubukhulu (iphaneli ye-VIP) ohlangothini lwangaphakathi lomnyango wekhabhinethi. Ukushisa kwayo kuyingxenye eyodwa kuphela kwe-polyurethane yendabuko, kunciphisa ukulahleka kokushisa komzimba womnyango ngo-40%. Ngesikhathi esifanayo, namathisela ukotini wokushisa we-aluminium foil composite (ubukhulu obungu-5mm) ngemuva nasemaceleni ekhabhinethi, ugxile ekumbozeni izindawo lapho i-condenser ixhumana khona nomhlaba wangaphandle ukuze kuncishiswe umthelela wokushisa okuphezulu ohlelweni lokuqandisa. Okwesibili, ukuze kuhlanganiswe izinga lokushisa lemvelo, faka inzwa yokushisa ngaphakathi kwamamitha ama-2 uzungeze isiqandisi. Lapho izinga lokushisa lemvelo lidlula ama-28℃, vula ngokuzenzakalelayo idivayisi yokukhipha umoya yendawo eseduze ukuze iqondise umoya oshisayo ezindaweni ezikude nesiqandisi ukuze igweme ukwakha imvilophu yokushisa.
4. Ukuthuthukisa isu lokusebenza: ukuzivumelanisa nezimo zokusetshenziswa ngokuguquguqukayo
Ngokusungula isu lokusebenza eliguquguqukayo elihambisana nezimo zokusetshenziswa, ukuzinza kokupholisa kungathuthukiswa ngaphandle kokwandisa izindleko zehadiwe. Setha imikhawulo yokulawula izinga lokushisa ngezikhathi ezahlukene: gcina umkhawulo ophezulu wokushisa okuqondiwe ku-8℃ ngesikhathi samahora ebhizinisi (8:00-22:00), bese wehlisa ku-5℃ ngesikhathi samahora angewona awebhizinisi (22:00-8:00). Sebenzisa izinga lokushisa eliphansi ebusuku ukuze upholise ikhabhinethi kusengaphambili ukuze ugcine umthamo obandayo webhizinisi losuku olulandelayo. Ngesikhathi esifanayo, lungisa umehluko wokushisa kokuvala ngokuya ngokuvama kokushintsha kokudla: setha umehluko wokushisa kokuvala okungu-2℃ (ukuvala ku-8℃, qala ku-10℃) ngezikhathi zokugcwalisa ukudla njalo (njengesikhathi sasemini) ukuze unciphise inani lokuqala nokuma kwe-compressor; setha umehluko wokushisa ongu-4℃ ngezikhathi zokushintsha kancane ukuze unciphise ukusetshenziswa kwamandla.
5. Ukuxoxisana ngokushintsha i-compressor
Uma imbangela eyinhloko yenkinga ukuthi amandla e-compressor mancane kakhulu ukuthi angafinyelela ku-2 ~ 8℃, kuyadingeka ukuxoxisana nekhasimende ukuze lithathe indawo ye-compressor, futhi umgomo wokugcina ukuxazulula inkinga yomehluko wokushisa.
Ukuze kuxazululwe inkinga yokwehluka kwezinga lokushisa lokupholisa lamafriji amancane ezentengiselwano, okubalulekile ukuthola izizathu ezithile, kungakhathaliseki ukuthi amandla amancane e-compressor noma iphutha ekwakhiweni kwepayipi lomoya, bese kutholwa ikhambi elifanele. Lokhu kusitshela nokubaluleka kokuhlolwa kwezinga lokushisa.
