I-Condenser ingenye yezinto eziphambili zokushintsha ukushisa eyunithi yesiqandisi.Umsebenzi wawo ukukhipha umhwamuko wesiqandisi oshisa kakhulu usuka ku-compressor, lapho ukushisa kukhishwa khona endaweni ezungezile bese kupholiswa, kufingqiwe kube uketshezi olugcwele, noma ngisho noketshezi olupholile kakhulu.
Ngokwendlela ehlukene yokupholisa kanye nendlela yokupholisa esetshenziswa i-condenser, kunezinhlobo ezintathu zokupholiswa kwamanzi, okupholiswa komoya kanye nokupholiswa komoya ngamanzi.
Imodi yokupholisa ye-Condenser:
Ukupholiswa komoya, ukupholiswa kwamanzi, ukuhwamuka-kupholile (umoya wamanzi upholisiwe)
Ngokuya ngemodi yokugeleza komoya ngaphandle kwepayipi emoyeni opholise i-condenser:
Icondenser yomoya wemvelo epholisiwe, i-condenser ephoqelekile yomoya opholile
Okokuqala, amanzi cooled condenser
Lolu hlobo lwe-condenser lusebenzisa amanzi njengendawo yokupholisa ukuze lususe ukushisa okuphuma lapho isiqandisi sijiya.Amanzi okupholisa angasetshenziswa kanye noma agaywe kabusha.
Uma kusetshenziswa amanzi ajikelezayo, imibhoshongo yokupholisa noma amachibi abandayo kufanele afakwe ukuze kuqinisekiswe ukuthi amanzi ahlala ephole.Ngokwesakhiwo sayo esihlukile, kukhona ikakhulukazi uhlobo lwegobolondo nohlobo lweshubhu kanye nohlobo lweshubhu nesishintshi sokushisa sepuleti esisetshenziswa manje.
Igobolondo elivundlile kanye ne-tube condenser
1. Igobolondo neshubhu condenser:
Amafriji ahlukene asetshenziswa emishinini yesiqandisi, futhi izici zabo zesakhiwo nazo zihlukile.Ngokuvamile, amagobolondo aqondile kanye nama-tube condensers afaneleka kumayunithi amakhulu esiqandisi e-ammonia, kuyilapho amagobolondo avundlile namashubhu amakhondeshi ngokuvamile asetshenziswa kumayunithi esiqandisi esikhulu naphakathi nendawo noma e-freon.Ipuleti leshubhu kanye neshubhu yokudlulisa ukushisa ngokuvamile kulungiswa ngendlela yokunweba, ukuze kube lula ukulungiswa nokushintshwa kweshubhu lokudlulisa ukushisa.
2. Izici zegobolondo elivundlile ne-tube condenser:
I-coefficient yokudlulisa ukushisa okuphezulu, ukusetshenziswa kwamanzi okupholisa kancane, ukusebenza okulula nokuphatha;Kodwa izinga lamanzi lezidingo zamanzi okupholisa liphezulu.Lolu hlobo lwedivayisi lusetshenziswa kakhulu kumayunithi esiqandisi amakhulu naphakathi njengamanje.
Igobolondo eliqondile kanye ne-tube condenser
I-1 - ipayipi yokuphuma kwamanzi;2 - isixhumi segeji yokucindezela;3 - ipayipi lokungenisa;4 – ithangi lokusabalalisa amanzi;5 - i-valve ehlangene yokuphepha;6 - ipayipi elilinganisa ingcindezi;7 - ipayipi elingenalutho;8 - I-Tubing
3. I-condenser yekesi:
Kuyi-condenser epholiswe ngamanzi eyenziwe ngamashubhu anobubanzi obuhlukene agundwa ndawonye futhi agotshwe abe yisimo esithandelayo noma isimo senyoka.Njengoba kuboniswe emfanekisweni, umhwamuko wesiqandisi ufinyezwa phakathi kwemikhono, futhi i-condensate ikhishwa ngezansi.Amanzi okupholisa ageleza phansi-phezulu epayipini lobubanzi obuncane, enze uhlobo oluphikisanayo nesiqandisi, ngakho-ke umphumela wokudlulisa ukushisa ungcono.
I-tube condenser
4. I-condenser yepuleti:
I-Plate condenser yenziwe ngochungechunge lwamapuleti ensimbi engagqwali, akha uketshezi olubandayo nolushisayo ezinhlangothini zombili zepuleti lokudlulisa ukushisa, futhi idlulise ukushisa ngodonga lwepuleti ngesikhathi sokugeleza.
Ugqinsi lwepuleti lokudlulisa ukushisa lucishe lube ngu-0.5mm, kanti isikhala samapuleti ngokuvamile singu-2-5mm.
I-Plate heat exchanger incane ngevolumu, ilula ngesisindo, iphezulu ekusebenzeni kahle kokudlulisa ukushisa, i-refrigerant encane edingekayo, ithembekile kakhulu futhi isetshenziswe kabanzi eminyakeni yamuva.Kodwa ivolumu yayo yangaphakathi incane, isiqandisisi se-liquid condensed kufanele siqedwe ngesikhathi, izidingo zekhwalithi yamanzi okupholisa ziphakeme, kunzima ukuhlanza, ukuvuza kwangaphakathi akulula ukulungisa.
Amanzi okupholisa ehla enyuka, umhwamuko oyisiqandisi ungena uvela phezulu, futhi isiqandisi esiwuketshezi sigeleza siphuma ngezansi.
Okwesibili, i-condenser yokupholisa umoya
I-condenser isebenzisa umoya njengendawo yokupholisa.Isiqandisi sijiya epayipini, futhi umoya ugeleza ngaphandle kwepayipi ukuze ubambe ukushisa okukhishwe umhwamuko oyisiqandisi osepayipini.Ngenxa ye-coefficient ephansi yokudlulisa ukushisa komoya, amaphiko avame ukubekwa ngaphandle kweshubhu (uhlangothi lomoya) ukuze kuthuthukiswe ukudluliswa kokushisa ngaphandle kweshubhu.Kunezinhlobo ezimbili zokugeleza komoya mahhala kanye nokugeleza komoya okuphoqelelwe.
1. I-condenser yokupholisa umoya enokungena komoya mahhala:
I-condenser isebenzisa umoya ogeleza ngaphandle kweshubhu ukuze imunce ukushisa okukhishwa yisiqandisi.Ukushintsha kokuminyana kubangela ukugeleza komoya okukhululekile futhi njalo kususa ukushisa kwe-condensation komhwamuko wesiqandisi.Ayidingi isiphephetha-moya, akukho msindo, isetshenziswa kakhulu kumayunithi amancane esiqandisi.Njengoba kukhonjisiwe esithombeni esingezansi:
I-condenser epholile enomoya egeleza ngempoqo: Njengoba kuboniswe emfanekisweni ongezansi, iqukethe isethi eyodwa noma amaningi amashubhu enyoka anamaphiko.Umhwamuko oyisiqandisi ungena eshubhu lenyoka usuka kumqoqi ongaphezulu, futhi i-fin yangaphandle yeshubhu isetshenziselwa ukuqinisa ukudluliswa kokushisa okuseceleni komoya futhi kunxephezele i-coefficient yokudlulisa ukushisa okuphansi kwendawo yomoya.
Ngokuya ngesakhiwo, imigqa yamashubhu engeziwe eduze kwesiqondiso sokugeleza komoya, kuncane ukudluliswa kokushisa komugqa ongemuva, ukuze amandla okudlulisa ukushisa angakwazi ukusetshenziswa ngokugcwele.Ukuze uthuthukise izinga lokusetshenziswa kwendawo yokushintshanisa ukushisa, kungcono ukhethe imigqa engu-4-6 yamapayipi.
2. Ukuqhathanisa phakathi kwecondenser epholile emoyeni kanye necondenser yamanzi epholile:
(1) Ezindaweni lapho amanzi okupholisa anele khona, ukutshalwa kwezimali kokuqala kanye nezindleko zokusebenza zempahla epholiswa ngamanzi ziphansi kunezisetshenziswa ezipholiswa ngomoya;
(2) Ngenxa yokushisa komoya ongaphandle okuphezulu ehlobo, izinga lokushisa lokufinqa lingafinyelela ku-50℃.Ukuze kutholwe umthamo ofanayo wokupholisa, umthamo we-compressor yesiqandisi yemishini epholisa umoya udinga ukunyuswa cishe ngo-15%;
(3) Isistimu yesiqandisi esebenzisa i-air cooled condenser ilula, engadambisa ukushoda kwamanzi;
Okwesithathu, i-evaporative condenser
1. I-evaporative condenser:
Ngamanzi nomoya njengendawo yokupholisa.Isebenzisa ukuhwamuka kwamanzi ukuze imunce ukushisa ukuze ihlanganise umhwamuko oyisiqandisi epayipini.Amanzi aphakanyiswa yiphampu bese efafazwa endaweni engaphandle yeshubhu lokudlulisa ukushisa ngombhobho ukwenza ifilimu yamanzi.Ingxenye yokushisa emunca amanzi iyahwamuka ibe isitimu samanzi, bese isuswa umoya ongena ku-condenser.
Amaconsi amanzi angahwamuki awela echibini elingezansi.I-baffle yamanzi ihlelwe ngaphezu kwebhokisi lomzimba.Isetshenziselwa ukuvimbela amaconsi amanzi ukuthi angaphumi emoyeni.Umgomo wesakhiwo se-evaporative condenser uboniswa emfanekisweni.
2. Izici ze-evaporative condenser:
(1) Ukusebenzisa ukuhwamuka kwamanzi ukususa ukushisa kwe-condensation, amanzi okupholisa asetshenzisiwe kuphela ukushajwa kwamanzi alahlekile, ukusetshenziswa kwamanzi okupholisa kuncane;
(2) Izinga lokushisa lebulb elimanzi elingenisa umoya lecondenser ehwamukayo linomthelela omkhulu ekushintshisaneni kokushisa.Kumazinga okushisa afanayo ajiyayo kanye nevolumu yomoya, uma izinga lokushisa lebulb elimanzi liba lincane, kuba mkhulu ukuhwamuka kwamanzi okupholisa, futhi kuba ngcono umphumela wokujiya.
(3) I-condenser ehwamukayo isebenzisa amanzi amancane, futhi umoya odingekayo ungaphansi kwe-1/2 yohlobo olupholile, ngakho ifaneleka ngokukhethekile ezindaweni ezomile ezinokuntuleka kwamanzi.
