Indlela yokusombulula ingxaki yokuvalwa kwenkqubo yefriji yinkxalabo yabasebenzisi abaninzi. Ukuvalwa kwenkqubo yefriji kubangelwa ikakhulu kukuvalwa kweoli, ukuvaleka komkhenkce okanye ukungcola okungcolileyo kwi-valve ye-throttle, okanye ukuvinjelwa okungcolileyo kwisihlunu sokumisa. Namhlanje ndiza kukunika isingeniso esicacileyo kwiimbangela kunye nezisombululo zokuxinana kwenkqubo.
1. Ukungaphumeleli kokuvalwa kweoyile
Isizathu esona sizathu sokuvala ioli kukuba i-compressor cylinder igugile kakhulu okanye i-cylinder fitting clearance inkulu kakhulu. Ipetroli ekhutshwe kwi-compressor ikhutshwe kwi-condenser, kwaye ingena kwisihlunu sokumisa kunye nefriji. Ngenxa ye-viscosity ephezulu yeoli, ivalwe yi-desiccant kwisihluzi. Xa kukho i-oyile eninzi kakhulu, yenza ukuvaleka kwindawo yokucoca, okubangela ukuba i-Refrigerant ingakwazi ukujikeleza kakuhle.
Ioli yefriji egqithisileyo ihleli kwi-system yefriji, echaphazela umphumo wefriji okanye ide ithintele ifriji. Ngoko ke, ioli yefriji kwisistim kufuneka isuswe.
Indlela yokujongana nokuvalwa kwe-oyile: Xa isihluzi sivaliwe, sitshintshe ngesitsha, kwaye usebenzise i-nitrogen yoxinzelelo oluphezulu ukuvuthela inxalenye yeoli yefriji eqokelelwe kwi-condenser. Kungcono ukusebenzisa isomisi seenwele ukutshisa i-condenser xa kuqaliswa i-nitrogen.
Ngendlela, inethiwekhi yefriji iya kuthetha ngefilimu yeoli apha. Isizathu esona sizathu sefilimu yeoli kukuba ioli yokuthambisa engazange ihlulwe ngumhluli weoli iya kungena kwinkqubo kwaye ihambe kunye nefriji kwi-tube, yenze umjikelezo weoli. Kusekho umahluko osisiseko phakathi kwefilimu yeoli kunye neplagi yeoli.
Iingozi zefilimu yeoli:
Ukuba ifilimu yeoli ibambelela kumphezulu wokushisa, ukushisa kwe-condensation kuya kunyuka kwaye ukushisa kwe-evaporation kuya kuhla, okubangelwa ukwanda kokusetyenziswa kwamandla;
Xa ifilimu ye-oyile ye-0.1mm ifakwe kumphezulu we-condenser, umthamo wokupholisa we-compressor yefriji iyancipha nge-16% kwaye ukusetyenziswa kwamandla kwanda nge-12.4%;
Xa ifilimu yeoli kwi-evaporator ifikelela kwi-0.1mm, ukushisa kwe-evaporation kuya kuhla ngo-2.5 ° C kwaye ukusetyenziswa kwamandla kuya kwanda nge-11%.
Indlela yokunyanga ifilimu ye-oyile:
Ukusetyenziswa kweoli ephezulu kunokunciphisa kakhulu inani leoli engena kumbhobho wenkqubo;
Ukuba ifilimu yeoli sele ikhona kwinkqubo, inokuxutywa nge-nitrogen ngamaxesha amaninzi de kungabikho igesi efana nenkungu.
2. Isithinteli somkhenkceukusilela
Ukwenzeka kokungaphumeleli kokuvaleka komkhenkce kubangelwa ikakhulu kukufuma okugqithisileyo kwinkqubo yesikhenkcisi. Ngokujikeleza okuqhubekayo kwefriji, umswakama kwinkqubo yefriji ngokuthe ngcembe ugxininisa kwi-outlet ye-valve ye-throttle. Ekubeni iqondo lokushisa kwi-outlet ye-valve ye-throttle yeyona iphantsi, iifom zamanzi. Umkhenkce uyakha kwaye ngokuthe ngcembe uyanda. Ukuya kumlinganiselo othile, ityhubhu ye-capillary ivalwe ngokupheleleyo kwaye ifriji ayikwazi ukujikeleza.
Imithombo ephambili yokufuma:
Umswakama oseleyo kumacandelo ahlukeneyo kunye nemibhobho yokudibanisa yenkqubo yefriji ngenxa yokomisa okunganeleyo;
Ioli yefriji kunye nefriji iqulethe ngaphezu komlinganiselo ovumelekileyo womswakama;
Ukungaphumeleli ukucoca ngexesha lofakelo okanye ukufakela okungafanelekanga kubangela ukufuma;
Iphepha lokugquma lemoto kwicompressor liqulethe ukufuma.
Iimpawu zokuvaleka komkhenkce:
Ukuhamba komoya ngokuthe ngcembe kuba buthathaka kwaye kuphazamisekile;
Xa uthintelo lunzulu, isandi sokuhamba komoya siyanyamalala, ukujikeleza kwefriji kuyaphazamiseka, kwaye i-condenser ngokuthe ngcembe iphola;
Ngenxa yokuvalwa, uxinzelelo lokukhupha luyanda kwaye isandi sokusebenza somatshini siyanda;
Akukho sikhenkcezisi esigeleza kwi-evaporator, indawo yokukhenkceza kancane kancane iba yincinci, kwaye umphumo wokupholisa uba mbi ngakumbi;
Emva kwexesha lokuvalwa, ifriji iqala ukuhlaziywa (ii cubes zeqhwa ezibandayo ziqala ukunyibilika)
Ukuvaleka komkhenkce kwenza ukuphindaphinda okuphindaphindiweyo kokucocwa okwethutyana, ukuvalwa okwethutyana, kuvinjwe emva koko kucocwe, kucocwe kwaye kuvinjwe kwakhona.
Unyango lokuvaleka komkhenkce:
Ukuvaleka komkhenkce kwenzeka kwisixokelelwano sesikhenkcezisi kuba kukho ukufuma okugqithisileyo kwisistim, ngoko ke yonke inkqubo yesikhenkcezisi kufuneka yomiswe. Iindlela zokulungisa zezi zilandelayo:
Phuma kwaye ubeke endaweni yesihluzo sokumisa. Xa isalathisi somswakama kwiglasi yokubona yenkqubo yefriji ijika ibe luhlaza, ithathwa njengefanelekileyo;
Ukuba isixa esikhulu samanzi singena kwinkqubo, yigungxule ngenitrogen ngokwezigaba, buyisela isihluzo, buyisela ioyile yesikhenkcisi, buyisela isikhenkcezisi, kunye ne vacuum de isalathisi sokufuma kwiglasi yokubona sijike sibe luhlaza.
3. Impazamo emdaka yokuvaleka
Emva kokuba inkqubo yefriji ivaliwe, ifriji ayikwazi ukujikeleza, ibangela ukuba i-compressor iqhube ngokuqhubekayo. I-evaporator ayibanda, i-condenser ayishushu, igobolondo ye-compressor ayishushu, kwaye akukho lizwi lokuhamba komoya kwi-evaporator. Ukuba kukho ukungcola okuninzi kakhulu kwisixokelelwano, isihluzi somiso siza kuvaleka kancinci kwaye isikrini sokucoca somatshini wokuthontsiza siya kuvaleka.
Izizathu eziphambili zokuvaleka okumdaka:
Uthuli kunye ne-metal shavings ukusuka kwinkqubo yokwakha kunye nofakelo, kunye nomgca we-oxide kwindawo yangaphakathi yodonga oluwa ngexesha lokudibanisa umbhobho;
Ngethuba lokucutshungulwa kwecandelo ngalinye, indawo yangaphakathi nangaphandle ayizange ihlambuluke, kwaye imibhobho ayizange ivalwe ngokuqinileyo kwaye uthuli lwangena kwimibhobho;
Ioli yefriji kunye nefriji iqulethe ukungcola, kunye ne-desiccant powder kwi-filter yokumisa ikhwalithi embi;
Ukusebenza emva kokuvaleka okumdaka:
Ukuba ivalwe ngokuyinxenye, i-evaporator iya kuziva ibanda okanye ibanda, kodwa akuyi kubakho qabaka;
Xa uchukumisa umphezulu ongaphandle wesomisi sokucoca kunye nevalve ye-throttle, iya kuziva ipholile xa ubamba, kwaye kuya kubakho iqabaka, okanye umaleko weqabaka emhlophe;
I-evaporator ayibanda, i-condenser ayishushu, kwaye igobolondo ye-compressor ayishushu.
Ukujongana nengxaki ezimdaka zokuvaleka: Ukuvaleka okumdaka kudla ngokubakho kwisihluzo sokumisa, isihluzo semesh ye-throttling mechanism, isihluzo sokufunxa, njl njl. Emva kokuba ukutshintshwa kugqityiwe, inkqubo yefriji kufuneka ihlolwe ukuvuza kunye nokucoca.
