Ubunjiniyela Kusasa Banciphisa Ukusetshenziswa Kwamandla Ezakhiwo Ezisetshenziswa Kaningi kanye Nezinhlelo Zokuphendula Isidingo Se-Aidsin
Ngo-1970, i-US Steel Corporation yakha indlunkulu eyingqayizivele esenezitezi ezingama-64 ngaphezu kwe-Pittsburgh, Pa., skyline. Yakhelwe ukuhlala iminyaka eyi-100, i-skyscraper manje eyaziwa ngokuthi i-US Steel Tower ihlukile ngokwezakhiwo. Ifaka umkhondo wezinyawo ongunxantathu ohlukile kusetshenziswa i-US Steel-developed COR-TEN® steel ukwenza isistimu yokubhinca yangaphandle evumela indaba ngayinye ukuthi iqukathe ihektare lendawo yaphansi. Ngenkathi ngaphambi kwesikhathi saso ngawo-1970, lesi sakhiwo sasala ngemuva nemishini eyafakwa lapho ama-kilowatt ebiza amapeni kanti uwoyela wawungu-$3 umphongolo ngamunye. Kungakho i-Winthrop Management, imenenja yezakhiwo, iqale uchungechunge lokubuyisela kabusha kusetshenziswa ama-Danfoss variable frequency drives (VFDs) ukunciphisa izindleko zamandla - okuholele ekongeni kuka- $1 million kanye nedumela eliluhlaza eliheha abaqashi.
"Besisebenzisa i-Danfoss VLT® Drives kumaphrojekthi ahlukahlukene wokubuyisela imali cishe iminyaka engu-15," kusho uGary Sechler, umphathi wobunjiniyela be-Winthrop Management. “Ngemuva kwesigaba ngasinye sephrojekthi yokubuyisela kabusha, sithole ukonga ugesi kuma-pump motors futhi abalandeli behle kakhulu. Ngakho sasizoqala esinye isigaba. Njengoba kunjena manje, sesifake ama-VLT® Drives angaphezu kuka-150 – nokunye okuzayo.”
Amadrayivu e-Danfoss ahlangabezana nezinselele zokubuyisela emuva
I-US Steel Tower enezitezi ezingu-64, engu-841-foot (256.34 m) eyake yaziwa ngokuthi i-USX Tower, ihlinzeka ngaphezu kwamamitha-skwele ayizigidi ezingu-2.3 wesikhala esingaqashiswa edolobheni lasePittsburgh. Yisakhiwo sebhilidi eside kunazo zonke kuleli dolobha futhi singesinye sezakhiwo eziphakeme kakhulu zezentengiselwano phakathi kweChicago nePhiladelphia - esinabaqashi abakhulu abahlanganisa i-US Steel kanye ne-University of Pittsburgh Medical Center (UPMC), ethatha amaphesenti angama-40 esikhala.
“Sihambisa amanzi amaningi nomoya phezulu, phansi, futhi sizungeze lesi sakhiwo,” kusho uSechler. “Amanzi ahlinzekwa ngamapayipi amanzi amabili angasebenzi. Ngaphezu kwalokho, kunamaphampu amanzi amane angasasebenzi, ayi-100-HP esakhiweni. Ngamunye angasebenza kuso sonke isakhiwo, uma kudingeka. Kukhona futhi amabhayela amabili esitezi samashumi ayisithupha nane kanye namafriji amathathu e-centrifugal esitezi samashumi ayisithupha nantathu ukuze anikeze ukufudumeza nokupholisa okungafuneki. Ngakho-ke kukhona ukumpompa okuningi okudingekayo ukuze kusetshenziswe amanzi ezindlini kanye nezihibe zamanzi abandayo, konke lokhu kudla amandla amaningi.”
Iphrojekthi yokuqala ye-VFD retrofit yaba ngonyaka wezi-2000 lapho ama-VLT® Drives asetshenziswa kumamotho amapompo angu-100-HP abhekele ukuhlinzekwa kwamanzi asekhaya ebhilidini.
"Amadrayivu amadala ayeyizinyathelo ezimbili njengoba ayesetshenziswa ezigayweni zensimbi emuva kosuku," kusho uJim Rice, umnikazi we-M&R Affiliates, omele abadayisi bakwaDanfoss obesebenza noSechler kusukela ephethe. “Ayengewona amadrayivu amafrikhwensi eqiniso. Siwashintshe safaka ama-Danfoss VLT® HVAC Drives amane alethe i-100 HP ngo-460 volts futhi anikeza isiqalo esithambile sangempela.”
NgokukaGary Sechler, isiqalo esithambile saqeda ukuguga okuningi kumamotho - saphinde sasindisa amandla. “Sikhuluma nezinjini ezinkulu ukuze zimpompe amanzi ethangini elingamamalitha angama-300 esitezi samashumi ayisithupha nane. Ukusuka lapho, amanzi ageleza emithonjeni, osinki, nezindlu zangasese ezingaphansi. Amaphampu amabili kuphela kwamane asebenza nganoma isiphi isikhathi ngokulandelana kwe-lead-lag eshintshana masonto onke. Kodwa izilawuli zejubane zezimoto ezindala zase ziphelelwe yisikhathi futhi izingxenye zazingasatholakali. Anginalo irekhodi lokonga amandla kusukela ngaleso sikhathi. Kepha ngiyazi ngokuqala okuthambile kuma-VLT® Drives, ukwakhiwa kabusha kwe-pump motor bekunguziro.”
Ithuba elilandelayo lokubuyisela liziveze ngemva kokuba izwe lasePennsylvania liphasise umthetho (PA ACT 129) ngoNovemba 2008 odinga Izinkampani Zokusabalalisa Ugesi ukuze zehlise ukusetshenziswa kukagesi kanye nesidingo esiphezulu. Ephendula, i-Duquesne Light ihlinzeke ngohlelo lwesaphulelo lwamabhizinisi afaka amadrayivu ashintshashintshayo ukuze athathele indawo ubuchwepheshe besitayela esidala sejubane lemoto.
“Sigxumele kulolu hlelo,” kusho uSechler. “Besazi ukuthi i-VLT® Drives yenzani kumaphampu ethu amanzi asendlini. Ngakho-ke ngo-2010, sabheka ukuthi yini abangayenzela ama-motor ethu amakhulu angu-200- kuya ku-250-HP. Laba balandeli basakaza umoya onomoya ezindaweni ezinkulu zamahhovisi ngengcindezi ethile emile ukuze banelise izinga lokushisa. Sigcine sesifaka amanye amadrayivu e-Danfoss angaba ngu-40 amamotho asukela ku-30 HP kuya ku-250 HP.”
“Sijabule kakhulu ngokongiwa kwamandla, ngoba amadrayivu anciphisa izindleko zikagesi ngo-$535,000 ngonyaka.
Futhi kanye nalezo zonga, sathola izaphulelo ezikhiqize imbuyiselo yonyaka owodwa. Ngakho-ke, ngokwemvelo, saqhubeka sifuna izindawo ezengeziwe zokusebenzisa amadrayivu. "
U-Rice uchaza ukuthi ukonga kukagesi okumangalisayo kuthathwe ku-physics "yemithetho ye-affinity," ethi ukwehlisa isivinini sepompo noma i-fan motor kunciphisa ukusetshenziswa kwamandla ngamandla. Okwesiboneloample, usebenzisa i-VLT®
“Izakhiwo ezifana ne-US Steel Tower zisebenzisa amaphesenti angu-40 awo wonke amandla asetshenziswa e-US Futhi maningi amathuba okunciphisa lokho kusetshenziswa ngokulawula izinjini ezingadingi ukuthi zigijime ngokugcwele. I-US Steel Tower iyisibonelo esihleampngalokho okungenziwa ubuchwepheshe be-variable frequency drive.”
UStanley Aranowski, Umphathi Wezentengiso Wesifunda, uDanfoss
Ukushayela okungehlisa isivinini sephampu ngamaphesenti angu-20 kuphumela ekongeni kwamandla okungafika kumaphesenti angu-50.
Ngo-2011, u-Sechler waqala iSigaba Sesibili sephrojekthi yokubuyisela kabusha. Nakulokhu, ama-VLT® Drives asetshenziswa ekupompeni amamotho - kodwa kulokhu kusetshenziselwa amanzi abandayo kanye nezihibe zamanzi okushisa ngaphambi kwesikhathi.
“Lezi zinjini zamaphampu zincane kakhulu kunalezo ezisetshenziselwa amaphampu amanzi asekhaya,” kusho uSechler. "Kodwa kukhona abaningi babo." Kule phrojekthi, ama-VLT® Drives asetshenziswe kumamotho amaphampu angu-40 asukela ku-50 HP kuya ku-200 HP. Futhi futhi, ukonga kwakumangalisa: izindleko zikagesi zonyaka zehliswa enye i-$ 138,000.
Ngo-2012, iphrojekthi yeSigaba Sesithathu yengeza amadrayivu ayi-16 amamotho angama-250-HP. Ngemva kokunwetshwa kweminyaka emithathu kwe-PA ACT 129, Isigaba Sesine sephrojekthi ngo-2013 sasebenzisa ama-VLT® Drives angaba ngu-40 kumapompo amancane angu-7.5- kuya ku-60-HP kanye nama-fan motors. Ngemuva kwesigaba ngasinye, ukonga kukagesi kwaba ngu-$317,000 kanye no-$152,000 ngonyaka, ngokulandelana.
Imiphumela enomthelela ekugcineni nesithunzi
“Ngo-2009, ukusebenzisa kwethu ugesi kwaba nesilinganiso samahora angama-kilowatts ayizigidi ezingama-65,” kusho uSechler. “Manje yehle yafinyelela ku-43 million kilowatts. Isidingo sethu esiphezulu sasingamamegawathi ayi-16 kuye kwayi-17; manje isingamamegawathi ayi-10. Lokhu ukonga okukhulu okuya ngqo emgqeni ophansi. Sekukonke, ama-Danfoss VLT® Drives acishe abe ngu-150 akhiqiza imali engaphezu kwesigidi esingu-$1.1 ngokonga amandla onyaka. Ngaphezu kwalokho, ukusebenza kahle kwamandla kwenza indawo ikhange kakhulu kubaqashi. Sesihlale kumaphesenti angama-98, okuyinto enhle kakhulu emakethe yanamuhla yezindawo ezithengiswayo.”
Ukuze ulawule ukufakwa, idrayivu ngayinye ihlanganisa i-Apogee® FLN njengephrothokholi yezokuxhumana ekhethekayo exhumeka nohlelo oluzenzakalelayo lokwakha (BAS). Amadrayivu ephampu alawulwa nge-Direct Digital Control yangaphakathi, ekala umehluko wengcindezi kuyo yonke iphampu ukuze ilawule isivinini sokushayela. Amalogi e-BAS ashayela idatha yokusebenza nokusetshenziswa kwamandla, okuhlanganisa nesimo sokushayela. Ithimba likaSechler lonjiniyela bangaphakathi nalo liyakwazi ukulandelela isimo sokusebenza - futhi liyajabula ukuthi akubanga khona isikhathi sokunciphisa ukushayela kusukela kwafakwa elokuqala eminyakeni eyi-15 edlule.
Ngokusho koMphathi Wezokuthengisa wakwa-Danfoss u-Stanley Aranowski, ukuqhubeka kwempumelelo yokubuyiselwa kwemali kuyikhredithi ku-SSI, Inc., uzakwethu wesevisi ka-Danfoss ozinze e-Cranberry Township, Pa. “I-SSI isetshenziselwe bonke abaqalayo kanye nenkonzo yocingo eyenza iphrojekthi efana nalena ibe mahhala. Ukwesekwa kwabo nobungcweti babo kuyimfihlo yokuqinisekisa iphrojekthi ye-VFD eyimpumelelo njengalena.”
U-Sechler uphinde aphawule ukuthi ukonga amandla okuvela ku-VLT® Drives kusiza ukunikeza isakhiwo igama eliluhlaza.
I-UPMC ifanelekele ezitezi ezingu-17 ezikuzo ukuthola isitifiketi se-LEED® esisiliva kanye neziyisithupha zokuthola isitifiketi se-LEED® segolide ngezinkonzo ze-evolveEA, inkampani yezokwakha esimeme kanye nenkampani yokubonisana. Ngaphezu kwalokho, i-Winthrop Management isayine i-US Steel Tower ku-Green Building Alliance 2030 District Challenge - ubambiswano lomphakathi nezizimele lwesifunda sokwakha esisenkabeni yedolobha i-Pittsburgh, olubophezela i-US Steel Tower ukunciphisa ukusetshenziswa kwamandla ngamaphesenti angu-50 ngo-2030. Ngo-April 2015, Isakhiwo siphinde sathola ukuqokwa ngoHlelo Lokusebenza Lwe-BOMA 360 lokuphumelela ekusebenzeni nasekuphatheni, okuhlanganisa ukusetshenziswa kwamandla nokuphathwa kwamandla.
“Siyabonga kuma-Danfoss VLT® Drives, sesivele sehlise ukusetshenziswa kwamandla ngamaphesenti angama-34,” kusho u-Sechler ngentshiseko. “UJim Rice kanye ne-SSI basebenze eduze nathi unyaka nonyaka ukuze bafake izicelo ngaphandle kwamaphutha. Hlanganisa ukonga amandla, ikhwalithi eqinile, nezaphulelo ezinciphisa izimbuyiselo zibe ngaphansi konyaka owodwa, angikwazanga ukujabula. Ngaphezu kwalokho, abaqashi bayajabula, futhi abanikazi bezakhiwo bajabule. Ngenxa ye-Danfoss VLT® Drives, i-US Steel Tower ingama ngokuziqhenya endaweni yase-Pittsburgh iminyaka eminingi ezayo.”
Lokhu okuqukethwe akumele kushicilelwe kabusha ngaphandle kwemvume yangaphambili evela kwa-Danfoss
U-Dantoss akakwazi ukwamukela isibopho ngamaphutha angaba khona kumakhathalogi, izincwajana nokunye okuphrintiwe. I-Dantoss igodle ilungelo lokushintsha imikhiqizo yayo ngaphandle kwesaziso. Lokhu kusebenza futhi emikhiqizweni esivele ine-oda inqobo nje uma izinguquko ezinjalo zingenziwa ngaphandle kokuba izinguquko ezilandelanayo zibe zidingekile emibhalweni osekuvunyelwene ngayo kakade.
Zonke izimpawu zokuhweba kule nto ziyimpahla yezinkampani ezifanele. I-Danfoss kanye nohlobo lwelogo ye-Danfoss yizimpawu zokuthengisa ze-Danfoss A/S. Wonke Amalungelo Agodliwe.
