I-Condenser yenye yezona zixhobo zokutshintsha ubushushu kwiyunithi yefriji.Umsebenzi wayo kukukhupha umphunga obushushu obuphezulu obushushu befriji ukusuka kwicompressor, apho ubushushu bukhutshelwa kwindawo engqongileyo kwaye bupholiswe, bujike bube bulwelo olugcweleyo, okanye ulwelo olupholileyo kakhulu.
Ngokwendlela yokupholisa eyahlukileyo kunye nendlela yokupholisa esetyenziswa yi-condenser, kukho iintlobo ezintathu zokupholisa kwamanzi, ukupholisa umoya kunye nomoya opholileyo wamanzi.
Imowudi yokupholisa yeCondenser:
Ukupholiswa komoya, ukupholiswa kwamanzi, ukupholisa amanzi ngomphunga (umoya wamanzi upholisiwe)
Ngokwendlela yokuhamba komoya ngaphandle kombhobho kwi-condenser epholileyo yomoya:
Umoya wendalo wokuhambisa umoya opholileyo wecondenser, ukuhambisa ngenkani umoya opholileyo wecondenser
Okokuqala, amanzi apholileyo condenser
Olu hlobo lwecondenser lusebenzisa amanzi njengendawo yokupholisa ukususa ubushushu obukhutshwayo xa ifriji ijiya.Amanzi okupholisa anokusetyenziswa kube kanye okanye asetyenziswe ngokutsha.
Xa kusetyenziswa amanzi ajikelezayo, iinqaba zokupholisa okanye amachibi abandayo kufuneka axhotyiswe ukuqinisekisa ukuba amanzi ahlala epholile.Ngokwesakhiwo sayo esahlukileyo, kukho ubukhulu becala iqokobhe kunye nodidi lwetyhubhu kunye nodidi lwetyhubhu kunye nepleyiti yokutshintsha ubushushu esetyenziswayo ngoku.
Igobolondo elithe tye kunye ne-tube condenser
1. Iqokobhe kunye ne-tube condenser:
Iifriji ezihlukeneyo zisetyenziselwa izixhobo zefriji, kwaye iimpawu zabo zesakhiwo nazo zihluke.Ngokubanzi, iqokobhe elithe nkqo kunye ne-tube condensers zilungele iiyunithi ezinkulu zesikhenkcisi se-ammonia, ngelixa iqokobhe elithe tyaba kunye ne-tube condensers zisetyenziswa ngokubanzi kwi-ammonia enkulu kunye nephakathi okanye iyunithi yefriji ye-freon.I-tube plate kunye ne-tube yokudlulisa ubushushu ngokuqhelekileyo igxininiswe yindlela yokwandisa, ukwenzela ukuba kube lula ukulungiswa kunye nokutshintshwa kwetyhubhu yokudlulisa ukushisa.
2. Iimpawu zeqokobhe elithe tye kunye ne-tube condenser:
I-coefficient yokudlulisa ukushisa okuphezulu, ukusetyenziswa kwamanzi okupholisa okuncinci, ukusebenza lula kunye nokulawula;Kodwa umgangatho wamanzi weemfuno zamanzi okupholisa uphezulu.Olu hlobo lwesixhobo lusetyenziswa kakhulu kwiiyunithi zefriji ezinkulu neziphakathi okwangoku.
Iqokobhe elithe nkqo kunye ne-tube condenser
I-1 - umbhobho wokukhupha ulwelo;I-2 - isinxibelelanisi sokulinganisa uxinzelelo;3 - umbhobho wokungenisa;4 – itanki yokuhambisa amanzi;I-5 - i-valve edibeneyo yokhuseleko;I-6 - umbhobho wokulinganisa uxinzelelo;I-7 - umbhobho ongenanto;8 - Iityhubhu
3. Casing condenser:
Yicondenser epholiswe ngamanzi eyenziwe ngeetyhubhu ezinobubanzi obahlukeneyo ezichetywa kunye kwaye zigotywe zibe ngqukuva okanye imilo yenyoka.Njengoko kubonisiwe kumzobo, umphunga wefriji ugxininiswe phakathi kwemikhono, kwaye i-condensate ikhutshwe ngaphantsi.Amanzi okupholisa ahamba ngaphantsi-phezulu kumbhobho omncinci we-diameter, okwenza uhlobo oluphikisanayo kunye nefriji, ngoko ke umphumo wokushisa ubushushu ungcono.
Umbhobho condenser
4. Icondenser yepleyiti:
I-Plate condenser yenziwe ngoluhlu lwamacwecwe ensimbi engenasici, eyenza umjelo obandayo kunye nobushushu obushushu kumacala omabini epleyiti yokudlulisa ubushushu, kwaye iqhubela phambili ubushushu ngodonga lweplate kwinkqubo yokuhamba.
Ubukhulu bepleyiti yokudlulisa ubushushu bumalunga ne-0.5mm, kwaye isithuba sepleyiti siqhelekile yi-2-5mm.
I-Plate heat exchanger incinci ngomthamo, ilula ngesisindo, iphezulu ekugqithiseni ubushushu obuphezulu, i-friji encinci efunekayo, iphezulu ekuthembekeni kwaye isetyenziswe ngokubanzi kwiminyaka yamuva.Kodwa umthamo wayo wangaphakathi uncinci, i-refrigerant yamanzi edibeneyo kufuneka ikhutshwe ngexesha, iimfuno zomgangatho wamanzi okupholisa ziphezulu, kunzima ukucoca, ukuvuza kwangaphakathi akulula ukulungisa.
Amanzi okupholisa aye enyuka esehla, umphunga wefriji ungena ukusuka phezulu, kwaye ifriji yolwelo iphuma ngaphantsi.
Isibini, i-condenser yokupholisa umoya
Icondenser isebenzisa umoya njengendawo yokupholisa.Ifriji igxininiswe kumbhobho, kwaye umoya uphuma ngaphandle kombhobho ukuze uthabathe ubushushu obukhutshwe ngumphunga wefriji kumbhobho.Ngenxa yomlinganiselo ophantsi wokudlulisa ubushushu bomoya, iifins zihlala zisetwa ngaphandle kwetyhubhu (icala lomoya) ukunyusa ukuhanjiswa kobushushu ngaphandle kombhobho.Kukho iindidi ezimbini zokuhamba komoya kunye nokuhamba ngenkani komoya.
1. Icondenser yokupholisa umoya ehamba simahla:
I-condenser isebenzisa umoya ogeleza ngaphandle kwetyhubhu ukufunxa ubushushu obukhutshwa sisikhenkcisi.Ukutshintsha kobuninzi kubangela ukuhamba komoya okukhululekile kwaye rhoqo kususa ukushisa kwe-condensation yomphunga wefriji.Ayifuni fan, akukho ngxolo, isetyenziswa ngakumbi kwiiyunithi ezincinci zefriji.Njengoko kubonisiwe kumfanekiso ongezantsi:
Icondenser epholileyo yomoya kunye nokuhamba komoya ngenkani: Njengoko kubonisiwe kulo mfanekiso ungezantsi, iqulathe iiseti enye okanye ezininzi zeetyhubhu ezinamaphiko.Umphunga wefriji ungena kumbhobho wenyoka ukusuka kumqokeleli ophezulu, kwaye i-fin yangaphandle yombhobho isetyenziselwa ukuqinisa ukuhanjiswa kobushushu becala lomoya kunye nokuhlawulela i-coefficient yokudlulisa ukushisa okuphantsi kwendawo yomoya.
Ngokubhekiselele kwisakhiwo, imiqolo emininzi yetyhubhu ecaleni kwendlela yokuhamba komoya, encinci ukuhanjiswa kobushushu kumqolo ongasemva, ukuze amandla okuhambisa ubushushu angasetyenziswa ngokupheleleyo.Ukuze kuphuculwe izinga lokusetyenziswa kwendawo yokutshintsha ubushushu, kungcono ukhethe imiqolo emi-4-6 yemibhobho.
2. Uthelekiso phakathi kwecondenser epholileyo yomoya kunye necondenser epholileyo yamanzi:
(1) Kwiindawo apho amanzi okupholisa anele, utyalo-mali lokuqala kunye neendleko zokusebenza zesixhobo sokupholisa amanzi zingaphantsi kunezo zixhobo zokupholisa umoya;
(2) Ngenxa yobushushu obuphezulu bomoya wangaphandle ehlotyeni, iqondo lobushushu lokujiya lingafikelela kuma-50.℃.Ukuze ufumane umthamo ofanayo wokupholisa, umthamo we-compressor yefriji yezixhobo ezipholileyo zomoya kufuneka zinyuswe malunga ne-15%;
(3) Inkqubo yesixhobo sokukhenkceza esebenzisa icondenser epholileyo yomoya ilula, enokuphelisa ukunqongophala kwamanzi;
Isithathu, i-evaporative condenser
1. I-evaporative condenser:
Ngamanzi kunye nomoya njengesixhobo sokupholisa.Isebenzisa i-evaporation yamanzi ukufunxa ubushushu ukujiya umphunga wefriji kumbhobho.Amanzi aphakanyiswa yimpompo aze atshizwe kumphezulu ongaphandle wetyhubhu yokuhambisa ubushushu ngombhobho ukwenza ifilimu yamanzi.Inxalenye yamanzi efunxa ubushushu iphuphuma ibe ngumphunga wamanzi, ize ithathwe ngumoya ongena kwicondenser.
Amathontsi amanzi angatshiyo awela echibini elingezantsi.I-baffle yamanzi icwangciswe ngaphezu komzimba webhokisi.Isetyenziselwa ukuthintela amathontsi amanzi ukuba angaphumi emoyeni.Umgaqo wesakhiwo se-evaporative condenser uboniswe kumzobo.
2. Iimpawu ze-evaporative condenser:
(1) Ukusebenzisa umphunga wamanzi ukususa ubushushu becondensation, amanzi okupholisa asetyenzisiweyo kukutshaja kwamanzi alahlekileyo kuphela, ukusetyenziswa kwamanzi okupholisa kuncinci;
(2) Ubushushu bebhalbhu emanzi yokungena emoyeni yecondenser engumphunga inefuthe elikhulu kutshintshiselwano lobushushu.Kubushushu obufanayo bokujiya kunye nomthamo womoya, okukhona ubushushu bebhalbhu emanzi yokungena ngaphakathi buba buncinci, kokukhona uba ngumphunga omkhulu wamanzi okupholisa, kwaye kokukhona isiphumo sokujiya singcono.
