Bheka, wonke umuntu ufuna ukusebenza kahle kangcono emazingeni okushisa apholile, kodwa iningi ligxumela liqonde ekuthuthukisweni kwabalandeli noma kumashejuli okuhlanza. Izinzuzo zangempela zivame ukucasha emininingwaneni oyibona ngemva kweminyaka ethile esizeni—njengokuthi iphimbo elithe ukucisha kancane ku-single fin tube bundle lingayilahla kanjani yonke iphrofayili yakho eshisayo, noma kungani i-mantra evamile yokuhlanza yonyaka ngezinye izikhathi iyindlela esheshayo yokumosha imali nezinkinga ezintsha. Ake sinqamule iseluleko esijwayelekile.
Isisekelo: Akukaze nje Ngokuphathelene nokugeleza komoya
Ngikubona lokhu ngaso sonke isikhathi. Umphathi weplanti ukhomba ibhange labalandeli bese ethi, Sidinga ukugeleza komoya okwengeziwe, ake sicacise injini ye-RPM ephakeme noma ifeni enkulu. Lokho kuyisinyathelo esiyiphutha sakudala. Ukugeleza komoya okwengeziwe ngokuvamile kusho ukudonsa amandla engeziwe, umsindo ophezulu, nokudlidliza okwenyukayo ngaphandle kwembuyiselo eqinisekisiwe emsebenzini wokupholisa. Umbuzo wokuqala kufanele uhlale uthi: ingabe ukugeleza komoya okukhona kusetshenziswa ngempumelelo? Ngikhumbula i-glycol cooler eyunithi ye-petrochemical lapho babefake khona amafeni asebenza kahle kakhulu kodwa badidwe amazinga okushisa amile. Udaba kwakungeyena umlandeli; kwakuyi- ukujikeleza kabusha komoya ngoba ama-plenum seals ayewohlokile. I-exhaust eshisayo isanda kungena ngaphakathi. Salungisa ukuvala ngomsebenzi wensimbi oyisisekelo futhi sabona ukwehla kwezinga lokushisa elingu-7°C. Azikho izingxenyekazi zekhompuyutha ezintsha.
Ukusebenza kahle kuqala ngokucabanga kwesistimu. Kufanele ucabangele i-triad: ukusebenza kwe-airside, ukusebenza kwe-tubeside, kanye nesimo somshini. Uma ulungiselela eyodwa ngokuhlukana, kungenzeka ukuthi udala ibhodlela kwenye indawo. Isibonelo, i-fin surface ehlanzekile ayinamsebenzi uma amashubhu angaphakathi ekhushulwa. Udinga indlela elinganiselayo.
Futhi ungathembi izimo zokuklama njengeqiniso lakho laphakade. Bayisithombe esifushane. Bengibuyekeza into epholile evela kumkhiqizi onedumela elihle—ake sithi inkampani efana ne-Shanghai SHENGLIN M&E Technology Co., Ltd, eyaziwa ngokubalisa kwayo ezimbonini—futhi umklamo wawuzwakala. Kodwa esizeni, iphrofayili yezinga lokushisa lomoya elizungezile yayihluke ngokuphelele kunesicaciso sokuqala ngenxa yezakhiwo ezintsha ezakhiwe eduze. I-cooler empeleni yayisebenza ephaketheni lomoya oshisayo. Kwadingeka senze imodeli yezimo ze-ambient zangempela, hhayi ezasezincwadini zokufunda, ukuze sihlonze ukushoda. Iwebhusayithi yabo, https://www.shenglincoolers.com, ibala imininingwane eqinile yobunjiniyela, kodwa ngisho nomklamo ongcono kakhulu udinga ukuqinisekiswa kwenkundla ngokumelene nezimo zomhlaba wangempela.
Ukuhlanza: Inkemba Esika Kabili
Yilapho ukunakekelwa okunenhloso enhle kungabuyisela emuva. Yebo, amaphiko angcolile abulala ukusebenza kahle. Kodwa ukuhlanza okunamandla kubulala amaphiko. Ngike ngabona inqwaba lapho amaphiko egobe khona ngokoqobo noma egugulwe emanzini anomfutho omkhulu noma ukugeza amakhemikhali okungafanele. Ukulahleka kwendawo engaphezulu kwe-fin kuhlala unomphela. Umgomo uwukubuyisela ukuthintana okushisayo, hhayi ukwenza inqwaba ibukeke iyintsha sha.
Senze umthetho olula: hlola-hlanza ingxenye encane. Sebenzisa amanzi anengcindezi ephansi (ngincamela ngaphansi kuka-700 psi) anethiphu elibanzi labalandeli, futhi uhlale ufutha ngokuqondana nobuso be-fin. Uma ubona ukungcola kuphuma kodwa amaphiko ahlale eqondile, umuhle. Uma udinga amakhemikhali, yazi i-fin material yakho. Amaphiko e-aluminium ane-asidi yokugeza? Udlala ngomlilo ngaphandle uma unephrothokholi yokungathathi hlangothi ephelele. Kwesinye isikhathi, ibhulashi elithambile le-bristle nomoya ocindezelwe wothuli olomile yilokho okudingayo. Ayibukeki ihlaba umxhwele kodwa igcina impahla.
Imvamisa ingolunye ugibe. Ngangisebenza embonini kamanyolo eyayihlanza yonke ikota ngokwenkolo. Ngemva kokubuyekeza, sithole ukuthi izinga lokungalungi laliphansi kakhulu izinyanga ezingu-8, lase likhuphuka phakathi nomkhankaso othile wokukhiqiza. Sishintshele ekuqapheni okusekelwe esimweni sisebenzisa isibhamu se-infrared esilula ukulandelela izinga lokushisa lesikhumba seshubhu ngokumelene nesisekelo esihlanzekile. Sandisa izikhawu zokuhlanza ngezinyanga ezi-5, songa amanzi, umsebenzi, futhi sehlisa ukuguga komshini kuma-bundle. Okubalulekile wukuqapha, hhayi ikhalenda.
Umhlangano Wabalandeli NeDrayivu: Ukulahlekelwa Okucashile Kuhlanganisa
Wonke umuntu ubheka ama-fan blade ukuze abone umonakalo, kodwa kuthiwani ngehabhu? Ihabhu egqwalile noma engalingani idlulisa ukudlidliza okumosha amandla futhi kugcizelele ibhokisi legiya. Sibe necala lokudonswa kwe-amp ephezulu enjinini. Kufakwe injini esikhundleni, akukho shintsho. Kuqondiswe kabusha idrayivu, ukuthuthukiswa okuncane. Ekugcineni, ngemva kokudonsa ifeni, sathola ukuthi ukukhiya kwe-taper kwangaphakathi kwehabhu kuphazamiseke kancane. Ibibangela ukushelela okwanele ukuze kuncishiswe iphimbo elisebenzayo, kuphoqe injini ukuthi isebenze kanzima. Ingxenye engu-$200 ibibangela izinkulungwane zezindleko zamandla engeziwe ngonyaka.
Amabhande nezithungu abasolwa abavamile, kodwa bavame ukusetha futhi bakhohlwe. Ibhande eliqine kakhulu liyakwandisa ukuthwala; okuxekethile kakhulu kubangela ukushelela nokushisa. Umthetho wesithupha wokuchezuka ulungile, kodwa ukusebenzisa i-sonic tension tester kungcono. Futhi fanisa amabhande akho-ungamane uphonse elisha elinesethi endala. Amabhande ahlanganisiwe abelana ngomthwalo ngokungalingani. Ngigcina ikhithi kumkhiqizi othize wamayunithi abalulekile ngoba ikhwalithi yebhande engahambisani iyinhloko yangempela.
Khona-ke kukhona imvume yephuzu labalandeli. Inkulu lena. Igebe phakathi kwethiphu ye-fan blade kanye ne-fan shroud. Uma inkulu kakhulu, umoya uvuza emuva, unciphisa ukusunduza okusebenzayo. Okuhlosiwe kuvame ukuba ngaphansi kuka-0.5% wobubanzi babalandeli, kodwa ungamangala ukuthi mangaki amayunithi asebenza ku-1% noma ngaphezulu ngenxa yokuguqulwa kwendwangu noma ukuhlangana okungafanele. Ukuyikala kudinga ubuhlakani obuthile ngamageji ezinzwa, kodwa ukuqinisa lelo gebe kuwukuwina okumsulwa, okungenazindleko.
Uhlangothi Lwenqubo: Ingxenye Ekhohliwe Yezibalo
Sigxila emoyeni, kodwa i-tubeside ibeka umthwalo wokushisa. Uma izinga lokugeleza kwenqubo yakho liphansi kunomklamo, noma izinga lokushisa lokungena lingaphezulu, alikho inani lokushintshwa kwe-airside elizofinyelela impoqo. Udinga ukwazi umsebenzi wakho wangempela. Ukufaka amageji okushisa angunaphakade nezikali zengcindezi kumaheda e-inlet ne-outlet kuwufanele isisindo sakho njengegolide ukuze kuhlolwe.
Isivinini se-Fluid sibalulekile. Iphansi kakhulu, futhi uthola i-stratification kanye nokungcoliswa; phezulu kakhulu, futhi uthola ukuguguleka. Ngikhumbula i-solvent cooler lapho ukwehla komfutho we-tubeside kwakukhuphuka. Umzwelo wemvelo kwakuwukucabanga ukukala. Kuvele ukuthi, ivalvu yokulawula ukugeleza komfula ibihluleka futhi ikhawulela ukugeleza, yehlisa isivinini, okwabe sekuvumela i-polymer ethambile ukuthi ifake kumashubhu. Silungise i-valve futhi sishaye amashubhu. Inkinga yayingekona ukusebenza kahle kwe-cooler; kwakuyisimo senqubo esiphoqa ukungasebenzi kuso.
Control Logic: Ungakuvumeli Ukulala Okuzenzakalelayo
Amayunithi esimanje anama-variable frequency drives (VFDs) nama-louver. Kodwa ingqondo yokulawula imvamisa ingeyakudala—ake sithi, indawo yokushisa elula eginqa bonke abalandeli phezulu naphansi ngazwi linye. Ebhange lamaseli amaningi, lokhu kungamosha. Ukushaqisa ukuqalisa kwabalandeli noma ukusebenzisa isu lokuhola/le-lag elisuselwe kuzinga lokushisa langempela le-ambient ye-bulb emanzi kungonga amandla abalulekile.
Iphrojekthi ene-multi-cell ephoqelelwe ukupholisa okusalungiswa kwe-compressor aftercooler ingifundise lokhu. Sihlele ama-VFD ukuthi agcine izinga lokushisa elithile lenqubo ngokulungisa kuphela isivinini sabalandeli ababili kwabane ngaphansi kwezimo ezijwayelekile. Ezinye ezimbili zahlala zivaliwe noma zinejubane elincane. Abalandeli abahamba phambili benze umsebenzi omningi. Silethe abalandeli be-lag ku-inthanethi kuphela ngesikhathi esishisa kakhulu sosuku noma phakathi nomthwalo ophakeme. Ukongiwa kwamandla bekucishe kube ngu-18% ngonyaka. I-Hardware yayinamandla, kodwa ifilosofi yokulawula yasekuqaleni ayizange yenziwe kahle.
Futhi, hlola ukubekwa kwenzwa yakho yezinga lokushisa. Uma isendaweni enokugeleza komoya okubi noma ukukhanya kwelanga, ufunda okungamanga, futhi isistimu yakho yokulawula yenza izinqumo ezisekelwe emangeni. Vala imigqa yezinzwa futhi ucabangele izihlangu zemisebe.
Umcabango Omuhle Okwanele nokuthi Ungawubiza Nini
Ekugcineni, yazi ukuthi kufanele ume nini. Ukuphishekela u-2% wokugcina wetiyori esebenza kahle kungase kudinge ukushintshwa kwenqwaba egcwele noma ukulungiswa kabusha komshini okunembuyiselo yeminyaka engu-20. Lokho akubona ubunjiniyela; lokho kuyi-accounting. Kwesinye isikhathi, isinqumo esisebenza kahle kakhulu ukugcina iyunithi isezingeni elanele ngenkathi uhlela ukushintshwa kwayo ngohlelo oluklanywe kangcono.
Ngixhumane namayunithi afakwe nezichibiyelo futhi alungiswa amashumi eminyaka. Ngesinye isikhathi, ukulahlekelwa okusebenzayo okunqwabelene okuvela kumaphiko agobile, ukuvinjelwa kwamashubhu, kanye nedizayini yabalandeli ephelelwe yisikhathi yenza ukubuyisela kabusha impi ehlulwayo. Izinkampani ezifana ne-SHENGLIN, esebenza ngobuchwepheshe bokupholisa izimboni, ngokuvamile zihlinzeka ngokuhlolwa kwe-retrofit okungaba yigugu kakhulu kunokulungisa okuncane. Inqwaba entsha enomklamo we-fin othuthukisiwe (njenge-crimped spiral fins vs. plain) noma iphakheji yabalandeli be-aerodynamic ingaba iphrojekthi ye-capex, kodwa i-ROI ingacaca uma iyunithi yakho ekhona isekupheleni kwempilo yayo esebenzayo.
Ngakho-ke, ithiphu yami eyinhloko? Phatha i-fin fan yakho epholile njengesistimu ephilayo. Yilalele (ngokwezwi nezwi, lalela ukudlidliza), yikale ngamathuluzi alula, futhi ungenelele ngokusekelwe kudatha nokubuka okuphelele, hhayi nje uhlu lokuhlola ukulungiswa. Izinzuzo ezinkulu zivela ekuqondeni ukusebenzisana phakathi kwazo zonke izingxenye zayo, hhayi ngokujaha inhlamvu yomlingo eyodwa.
