Uzwa okuningi mayelana nama-drycoolers kanye nokusimama kulezi zinsuku, kodwa ake sidlule ku-fluff yokuthengisa. Isixhumanisi sangempela asikona nje ukonga amanzi, nakuba lokho kuyingxenye enkulu. Imayelana nawo wonke amandla kanye nokubala kwensiza eguquguqukayo lapho ususa umbhoshongo wokuhwamuka ku-equation. Ngike ngabona amaphrojekthi lapho i-pitch yokusimama yayiwukucatshangelwa kwamuva, kanti amanye lapho bekuyiyona nto ehamba phambili. Umehluko ngomphumela ugqamile.
I-Arithmetic Yamanzi Ebalulekile
Wonke umuntu ugxumela esihlokweni sokusetshenziswa kwamanzi okuyiziro. Kuyiqiniso, i-drycooler yenqaba ukushisa ngomoya kuphela, ngakho-ke awuhlali uqokomisa umbhoshongo wokupholisa ngenxa yokuhwamuka, ukukhukhuleka, nokuwohloka. Kodwa inzuzo yokusimama akuyona nje ivolumu oyilondolozile. Amakhemikhali okwelapha ongawathumeli futhi ongawaphathi, amanzi angcolile okubhodlozwayo okungadingeki ukuba uwaphathe noma uwakhokhele izindleko zepayipi lendle, kanye nengozi ye-legionella oyiklama ngempumelelo ngaphandle kwesistimu. Ngikhumbula imboni yokugaya ukudla endaweni enamanzi amaningi; umshayeli wabo oyinhloko kwakungeyona ngisho nezindleko zamanzi, kodwa ikhanda elilawulayo kanye nesibopho sokukhishwa kwamanzi angcolile embhoshongweni wabo omdala. Ukushintshela ebhange lama-drycoolers kwaba ukunqoba kokusimama kokusebenza okungaphezu kwe-capex ehlanzekile.
Lapho abantu bekhubeka bacabanga ukuthi lesi yisidlo sasemini samahhala. Akunjalo. Amandla efeni okunyakazisa ivolumu yomoya edingekayo angaphezulu kwamandla epompo yombhoshongo. Ngakho-ke uhweba ngamanzi ngogesi. Umbuzo wokusimama uba: athini amandla ekhabhoni alowo gesi wegridi uma kuqhathaniswa nokushoda kwamanzi endawo namandla okwelapha? Ezindaweni ezinegridi ehlanzekile uma kuqhathaniswa noma ezivuselelekayo endaweni, ukuhwebelana kutsheka kakhulu kuvumela i-drycooler. Ngasebenza kuphrojekthi yesikhungo sedatha eScandinavia lapho le calculus yayiphelele khona—igridi esebenza ngamanzi, umoya obandayo omningi isikhathi esiningi sonyaka. Yabo i-drycooler ama-array asebenza ngomthwalo oyingxenye we-70% wonyaka, ama-compressor avaliwe. I-PUE yonyaka yayibukeka iyinhle.
Kukhona okuhlukile okunamayunithi ayingxube—ama-drycoolers ane-adiabatic pre-cooling pad. Basebenzisa ingxenye encane yamanzi ombhoshongo wokupholisa, bafafaze kuphela lapho isibani esomile esisendaweni siphezulu ngokwanele ukuze kugunyazwe ukuthuthukiswa kokusebenza kahle. Yilapho ukusimama okungokoqobo kuhlala khona: ukuthuthukisa ukusetshenziswa kwensiza, hhayi ukuqeda eyodwa. Iklayenti ligcizelele ohlelweni olomile olumsulwa endaweni eswakeme ye-Gulf Coast. I-chiller lift yayinesihluku kulo lonke ihlobo, i-spiking energy ukusetshenziswa. Sifake kabusha izingxenye ze-adiabatic kamuva. Siyini isifundo? Ukusimama kufanele kuhlolwe phakathi nomjikelezo waminyaka yonke, hhayi nje ukwakheka okuphezulu.
Impahla Nobude Obude: Umjikelezo Okukhulunywa Ngawo Kancane
Ake sikhulume ngehadiwe. Umbhoshongo wokupholisa ovamile unesitsha, imidiya yokugcwalisa, izinto zokuqeda ukukhukhuleka, imibhobho—ipulasitiki eminingi, i-PVC, noma kwezindala, ukhuni. Lokho kugcwaliswa kuyehlisa isithunzi, konakale, kudinga ukushintshwa. Uhlelo lokuhlanza amanzi lungenye i-suite yezingxenye. A i-drycooler ilula ngokuyisisekelo: amakhoyili (ngokuvamile amaphiko e-aluminium ethusi noma amashubhu angenasici), amafeni, kanye nohlaka. Izingxenye ezimbalwa zisho i-carbon ehlanganiswe kancane ekukhiqizeni kanye nokusakaza okuncane kwemfucuza ekupheleni kwempilo. Ngike ngaya kumasayithi akhulula imibhoshongo emidala; ukulahla izinkuni ezihlanjululwe kanye nodaka olungcolile kuyiprojekthi ngokwayo.
Ukugqwala kuyisitha esikhulu. Kwi-drycooler, ikhoyili iyindawo yempi. Endaweni ehlanzekile, eyomile, ingahlala iminyaka engama-20+. Kodwa ngike ngabona amakhoyili ezindaweni ezisogwini noma ezisindayo zezimboni edliwa ephila esikhathini esingaphansi kweminyaka eyishumi uma isitokwe se-fin singakhethwanga ngendlela efanele. Lokho ukwehluleka kokusimama - ukushintshwa kusenesikhathi. Izinkampani ezifana I-Shanghai SHENGLIN M&E Technology Co., Ltd, okuyinto njengomkhiqizi ohamba phambili egxile ekupholiseni kwezimboni, ngokuvamile igcizelela lokhu. Babephusha amaphiko e-epoxy-coated noma amakhoyili amancane e-aluminium yonke indawo ezindaweni ezinolaka. Kubiza kakhulu kusengaphambili, kodwa ukunwetshwa komjikelezo wempilo kuyisinqumo esimeme. Kuyikholi yokwahlulela esekelwe ezimeni zangempela zesayithi, hhayi i-spec sheet sheet-tick.
Bese kuba nesekhethi yesiqandisi. Kusistimu ye-chiller-drycooler, uqukethe isiqandisi. Embhoshongweni omdala ovulekile, uhlala ulahlekelwa amanzi (uphethe amakhemikhali okwelapha) endaweni ezungezile. Imvelo ye-loop evaliwe yesistimu ye-drycooler iqukethe isiqandisi esinamandla se-GWP, esinciphisa ingozi yokuvuza. Lesi sici sokuqukethwe sinomthelela oqondile ekuphepheni kwemvelo kokusebenza, into eba yingxenye enkulu yokubika kokusimama.
Ukuhlanganisa Nokulawula: Lapho Ukusebenza Kuyabonakala noma Kulahlekile
Ihadiwe yinto eyodwa; indlela oyiqhuba ngayo yonke into. Umnikelo wokusimama we-drycooler usetshenziswa kakhulu ukulawula okuhlakaniphile. Iphutha lakudala ligijima bonke abalandeli ngesivinini esigcwele ngokusekelwe kusignali eyodwa yokucindezela kwekhanda eliphezulu. Ushisa i-kWh. Imvamisa eshintshashintshayo yesimanje kubalandeli nokuhlanganisa isilawuli se-drycooler ne-microprocessor ye-chiller kubalulekile. Ukusebenzisa izinga lokushisa le-ambient kubalandeli besiteji futhi unike amandla ukupholisa kwamahhala (lapho amanzi abandayo apholiswa khona ngokuqondile nge-drycooler loop ngaphandle kokusebenza kwe-compressor) kuyi-grail engcwele.
Ngikhumbula i-retrofit embonini eyenza imithi. Babenama-drycoolers kodwa babewasebenzisa njenge-condenser elula. Sihlanganise i-valve yokushintsha epholile yamahhala efanele kanye nesilawuli esilandelanayo esibheka isibani esimanzi (sombhoshongo wawo omdala) kanye ne-dry-bulb (komshini omusha opholile), sikhetha indlela esebenza kahle kakhulu yokwenqaba ukushisa ngesikhathi sangempela. Ukonga amandla entwasahlobo nekwindla okukhokhelwe ukuthuthukiswa kwezilawuli eminyakeni emibili. Leyo yimisebenzi esimeme: ukusebenzisa ubuhlakani ukukhulisa ukusebenza kahle kwempahla.
I-flip side iwukunakekela. Uma amakhoyili engcolile, ukugeleza komoya kuyehla, umfutho uyakhuphuka, futhi ukusebenza kahle kuyehla. Ukuzinza kudinga isiyalo sokusebenza. Ukuhlola okulula kwekota kanye nokuhlanza ikhoyili okuhleliwe—okubaluleke kakhulu kunalokho abaningi abakuqaphelayo. Ngibone ukusebenza kahle kwehla ngo-15-20% kusuka kungqimba lothuli ne-lint, okuphoqa ama-compressor ukuthi asebenze kanzima, asule inzuzo ye-carbon yesistimu. Akuwona ubukhazikhazi, kodwa kuyiqiniso.
Ukupholisa Njengesivivinyo Somcabango Wesevisi
Yilapho ukucabanga kwami bekuhamba khona muva nje. Uma sibheka ukusimama njengengqikithi yomjikelezo wempilo, khona-ke imodeli yebhizinisi ibalulekile. Kuthiwani uma, esikhundleni sokuthengisa i-drycooler, umkhiqizi ofana ne-SHENGLIN agcine ubunikazi futhi wathengisa umthamo wokupholisa noma izinsizakalo zokwenqaba ukushisa? Isikhuthazo sabo siyashintsha kusukela ekuthengiseni ibhokisi kuye ekwandiseni ubude balo besikhathi eside nokusebenza kahle. Bangacacisa ukuvikelwa kokugqwala okungcono kakhulu, izilawuli ezihlakaniphe kakhulu, abalandeli abaqine kakhulu—ngoba bangabanikazi bengcuphe yokusebenza nezindleko zokuyilungisa.
Lokhu kuqondanisa ukusimama nezinzuzo zebhizinisi. Iklayenti lithola i-OPEX ebikezelwayo nokusebenza okuqinisekisiwe, kuyilapho umhlinzeki egqugquzelwa ukuba anciphise inani lamandla nokusetshenziswa kwensiza eminyakeni engu-20. Ngifake lo mbono; isithiyo i-capital accounting kanye namamodeli okwabelana ngengozi. Kodwa ezimisweni zomnotho eziyindilinga zangempela, ukusuka kumkhiqizo uye enkonzweni kuyisici esinamandla. I-drycooler, enokwakheka kwayo okulula, okuhlala isikhathi eside, ngokungangabazeki ifaneleka kangcono kulo modeli kunombhoshongo wokupholisa oyinkimbinkimbi, oncike emanzini.
Iphinde iguqule ifilosofi yokuklama. Ungayikhulisa kancane ikhoyili ukuze uthole isivinini esiphansi sobuso namandla efeni, wazi ukuthi izindleko zempahla ezengeziwe zikhokhiswa ishumi leminyaka lezikweletu zamandla aphansi. Ungafaka ukuhlunga okungcono kusukela ngosuku lokuqala. Lezi yizinketho ezicashile, eziqhutshwa isipiliyoni ezivame ukuphuthelwa yiphepha elithile noma ithenda yebhidi ephansi kakhulu, kodwa enqwabelana ibe izinzuzo zokusimama ngokuhamba kwesikhathi.
Isiphetho: Umdlalo Wesistimu, Hhayi Inhlamvu Yesiliva
Ngakho-ke, ingabe i-drycooler ithuthukisa ukusimama? Yebo, kodwa ngokwemibandela. Kuyithuluzi elihle lokunciphisa ukusetshenziswa kwamanzi, ukusetshenziswa kwamakhemikhali, kanye nobungozi bokusebenza kwamanzi. Kwenza ukunakekelwa kube lula futhi kungaba nempilo ende yesevisi ngezinto ezifanele. Amandla ayo avulwe ngokugcwele ngezilawuli ezihlakaniphile nokuhlanganiswa okufanele ukuze kunikwe amandla ukupholisa kwamahhala.
Kodwa akukhona ngokuzenzakalelayo ukukhetha okuluhlaza kuzo zonke izimo. Uma iwiswe endaweni eshisayo, enothuli ngaphandle kokulawula ukupholisa kwamahhala kanye nogesi oshibhile, obaselwa ngamalahle, i-carbon footprint iyonke ingaba yimbi kakhulu kunombhoshongo onakekelwa kahle. Ukuthuthukiswa kuvela ekubukeni okuphelele: imikhawulo yensiza yendawo, ingxube yamandla, idizayini yesistimu, kanye—ngokubalulekile—indlela esetshenziswa futhi inakekelwa ngayo ukuphila kwayo okugcwele.
Amaphrojekthi esimeme kunazo zonke engike ngahileleka kuwo aphatha i-drycooler hhayi njengengxenye eyodwa, kodwa njengengxenye eyinhloko yesu lokusebenza kahle kwesistimu. Bayibhanqe nama-chillers asebenza kahle kakhulu, ukugeleza okuyisisekelo okuguquguqukayo, nokuhlanganiswa kwesistimu yokuphatha izakhiwo. Yilapho ubona izinombolo zangempela zihamba. Izingxenyekazi zekhompuyutha zinika amandla isu, kodwa isu, elizalwa ngokuhlangenwe nakho okungokoqobo kanye nezifundo ezimbalwa ezinzima, liletha ukusimama.
