I-Precise Control Logic kanye Ne-Energy Efficiency Optimization of Fan and Spray Systems in Closed-Circuit Cooling Towers
Kusistimu yokusebenza yezinhlelo zokupholisa zezimboni, ukulawulwa kwamafeni namasistimu wokufutha{0}kumibhoshongo yokupholisa eyiziyingi evaliwe kungabizwa ngokuthi "umgogodla ohlakaniphile". Akusona isiqalo esilula{2}}sokumisa okokusebenza, kodwa isistimu yebhalansi eguquguqukayo eyakhiwe eduze kwezinga lokushisa le-outlet loketshezi olucutshungulwayo, oludinga ukuthola isisombululo esiphelele phakathi kokusebenza kahle kokupholisa, ukusetshenziswa kwamandla nokusetshenziswa kwemithombo yamanzi. Umqondo wayo oyinhloko ukuthatha izinga lokushisa elimisiwe loketshezi lwenqubo njengesilinganiso, futhi ulungise ngobuhlakani ingxenye yokushintshisana kokushisa okunengqondo nokushintshashintsha kokushisa okucashile ngokuqapha{4}}isikhathi sangempela samapharamitha emvelo (njengezinga lokushisa elimanzi-le-bulb, izinga lokushisa elomile{6}}le-bulb, isivinini somoya) kanye nomthwalo wesistimu (inhloso yokufaka ukushisa okupholisayo kanye nokugeleza okuqondisiwe kokupholisa kwesistimu ekugcineni kufinyelele izinga lokushisa elipholile " izindleko zokusetshenziswa kwamandla".
Incazelo Yemikhiqizo
Ngokombono wesimiso sokushintshisana kokushisa, inqubo yokupholisa-yemibhoshongo yokupholisa eyindilinga evaliwe iwukusebenzisana kokushintshisana kokushisa okunengqondo nokushintshisana kokushisa okucashile.
Uketshezi lwenqubo lujikeleza kukhoyili evaliwe, futhi ukushisa kudluliselwa ngaphandle ngodonga lwamakhoyili; ukubambisana phakathi kwesistimu yokufutha kanye nesiphephetha-moya ukulungisa ingxenye yezindlela ezimbili zokushintshanisa ukushisa ngokushintsha izimo zokushintshanisa ukushisa ngaphandle kwekhoyili.
Uma izinga lokushisa le-ambient-bulb liphansi (njengasebusuku, ebusika noma ngezinsuku zemvula) futhi umthwalo wokupholisa usebangeni lokukhanya, isistimu yokulawula izobeka kuqalaimodi-yokusetshenziswa kwamandla ephansi- ngalesi sikhathi, asikho isidingo sokuvula ifeni, kuqalwa kuphela iphampu yesifutho. Inani elincane lamanzi okufuthwa lifafazwa ngokulinganayo phezu kwekhoyili ukuze lenze ifilimu yamanzi elincanyana nelifanayo.
Ngemva kokuba ifilimu yamanzi ihlangana nomoya, ukuhwamuka kwemvelo kwenzeka, futhi inani elikhulu lokushisa kukhoyili liyasuswa ngokushintshaniswa kokushisa okucashile. Le nhlanganisela "yokupholisa okuhwamukayo + nokungenisa umoya kwemvelo" isebenzisa kuphela amandla okusebenza ephampu yesifutho (imvamisa kuphela i-1/5 kuya ku-1/3 yamandla efeni), okulingana nokubona "ukupholisa kwamahhala" nokunciphisa kakhulu izindleko zokusebenza phakathi nesikhathi sokulayisha ukukhanya.
Ngesikhathi esifanayo, ukugwema ukulahleka kokugeleza kwamanzi okubangelwa ifilimu yamanzi aminyene kakhulu, isistimu izohlola isikhathi sangempela-ivolumu yamanzi afuthwayo ngenzwa yokugeleza futhi iwalawule ebangeni elifanele "lokuvala ikhoyili ngaphandle kokuconsa ngokweqile", kuqhubeke nokunciphisa ukungcola kwemithombo yamanzi.
Incazelo Yemikhiqizo
Lapho izimo zemvelo ziwohloka (njengokushisa okuphezulu ehlobo, isimo sezulu esomile nesishisayo) noma umthwalo wenqubo ukhuphuka (njengokusebenza-nomthwalo ogcwele wezinto zokusebenza zokukhiqiza kanye nokwenyuka kwezinga lokushisa lokungenisa uketshezi olucutshungulwayo), ukuhwamuka kwemvelo kwamanzi okufuthwayo kukodwa ngeke kusahlangabezana nesidingo sokupholisa.
Ngalesi sikhathi, isistimu yokulawula izoqala imodi yokuthuthukisa i-synergistic - kuqala kancane kancane inyuse isivinini sephampu yesifutho ukuze kwenyuswe umthamo wamanzi wokufutha. Uma izinga lokushisa lokukhipha impahla lisephezulu kunenani elimisiwe, ifeni izoqalwa ngokunqumayo. Ukungenelela kwe-fan kungabizwa ngokuthi "i-qualitative change switch" yomthamo wokupholisa: ngokusebenzisa i-convection ephoqelelwe, ingenisa inani elikhulu lomoya ozungezile embhoshongweni, odlula ngokushesha phezu kwekhoyili embozwe ifilimu yamanzi.
Ukwenyuka kwesivinini sokugeleza komoya akusheshisi nje kuphela izinga lokuhwamuka kwefilimu yamanzi (ukushintshaniswa kokushisa okucashile kwandisa izikhathi ezingu-3-5) kodwa futhi kuthuthukisa umehluko wokushisa phakathi komoya nodonga lwekhoyili (ukusebenza kahle kokushintshaniswa kokushisa okunengqondo kwandisa izikhathi ezingu-1-2). Ngaphansi komphumela okabili, amandla okukhipha ukushisa kwesistimu akhuphuka nge-oda lobukhulu.
Ngalesi sikhathi, ifeni kanye nephampu yesifutho kungena esimweni sokusebenza esihlanganisiwe. Kodwa-ke, ubuqili besistimu yokulawula yesimanje iwukuthi ayivumeli kokubili ukusebenza ngomthwalo ogcwele ngaso sonke isikhathi, kodwa ibona "ukulungiswa okungenasinyathelo" ngobuchwepheshe bokuguqulwa kwemvamisa. Uma sithatha ifeni njengesibonelo, isistimu yokulawula izolungisa isikhathi sangempela-isikhathi sokulungisa isivinini sabalandeli ngesiguquli semvamisa ngokuya ngokuchezuka phakathi kwezinga lokushisa langempela le-outlet yoketshezi lwenqubo kanye nenani elimisiwe: uma izinga lokushisa lokukhipha impahla lingaphezulu kancane kunevelu emisiwe, ifeni izosebenza ngesivinini esiphansi esingu-30% -50%; uma ukuphambuka kukhuphuka, ijubane lizokhuphuka kancane kancane libe ngumthwalo ogcwele.
Umphumela wokulondoloza amandla-wale ndlela yokulungisa ubaluleke kakhulu - njengoba ukusetshenziswa kwamandla kwefeni kulinganiswa nekhyubhi yesivinini sayo, lapho isivinini sehla sisuka ku-100% siye ku-70%, ukusetshenziswa kwamandla kungancishiswa cishe ngo-65%, okunciphisa kakhulu ukumoshwa kwamandla ngaphansi komthwalo oyingxenye.
Ukulawula okucolisisiwe kwesistimu yesifutho nakho akunakuhlukaniswa nobuchwepheshe bokuguqula imvamisa kanye-nesu lokuhlanganisa amaphampu amaningi. Emibhoshongweni yokupholisa-emikhulu evaliwe{3}yeziyingi, 2-amaphampu okufuthwa angu-3 avamise ukufakwa. Uhlelo lokulawula luzokwamukela indlela emibili "yokulungiswa kwenombolo + ukulungiswa kwejubane" ngokusho koshintsho lomthwalo: ipompo eyodwa kuphela iqalwa futhi isetshenziswe ngesivinini esiphansi ngaphansi komthwalo ophansi; iphampu eyodwa{8}egcwele isivinini noma amaphampu anesivinini esiphansi amabili aqalwa ngaphansi komthwalo ophakathi nendawo; wonke amaphampu aqalisiwe futhi aqhutshwa ngesivinini esigcwele kuphela ngaphansi komthwalo omkhulu.
Lokhu kulungiswa okuhlanganisiwe akuvimbi kuphela inkinga yokusetshenziswa kwamandla "yehhashi elikhulu elidonsa inqola encane" ngephampu eyodwa enkulu kodwa futhi kuthuthukisa ukwethembeka kwesistimu ngokusebenzisa{0}}ukungafuneki okuningi kwamaphampu. Ngesikhathi esifanayo, amanye amasistimu athuthukisiwe azophinde amise ivalvu elawula i-bypass epayipini lokufutha.Lapho umswakamo wendawo uphezulu kakhulu (njengasenkathini yemvula ye-plum) futhi ukusebenza kahle kokuhwamuka kwefilimu yamanzi kuncipha, i-valve yokudlula izovuleka ngokuzenzakalelayo, iqondise ingxenye yamanzi yesifutho ukuthi ibuyele ethangini lamanzi ukuze kwehliswe ivolumu yesifutho esingavumelekile.Lokhu akunciphisi kuphela ukusetshenziswa kwamandla empompi yamanzi kodwa futhi kuvimbela ukwakheka kwesikali endaweni yekhoyili ngamanzi engeziwe (isikali sizokwandisa ukumelana nokushisa futhi sinciphise ukusebenza kahle kokupholisa ngo-10% -20%).
Incazelo Yemikhiqizo
Ngaphezu kwesu lokulungisa ngaphansi komthwalo ojwayelekile, uhlelo lokulawula ludinga futhi ukubhekana nezimo zokusebenza ezidlulele kanye nezimo zamaphutha ukuze kuqinisekiswe ukuzinza kokusebenza. Isibonelo, uma izinga lokushisa le-ambient lehla kakhulu (njengezinga lokushisa elingaphansi kuka-0℃ebusuku ebusika), ukuze kuvinjelwe umonakalo wemishini obangelwa ukuqhwa kwefilimu yamanzi ngaphandle kwekhoyili, isistimu yokulawula izomisa ngokuzenzakalelayo iphampu yesifutho, iqale ifeni bese ivula "i-anti{2}}idivayisi yokushisisa iqhwa" ngesikhathi esifanayo. Ngokugeleza komoya okuphoqelekile nokushisa kwendawo, izinga lokushisa elingaphezulu lekhoyili ligcinwa ngaphezu kwe-5 degree; uma ifeni yehluleka (njengokugcwala kwemoto, ukugxuma kwe-blade), isistimu izothumela ngokushesha isignali ye-alamu, inyuse umthamo wamanzi okufuthwa ngesikhathi esifanayo, futhi ivule "ipayipi lokudlula eliphuthumayo" ukuze lethule ingxenye yoketshezi lwenqubo kusekethe yokupholisa ebekwe eceleni ukuze kugwenywe izinga lokushisa eleqile lenqubo. Ukwengeza, isistimu izophinde ihlole isikhathi sangempela-isikhathi sokuqapha izinga lamanzi lamanzi afuthwayo (okufana nokuhamba kahle, inani le-pH), futhi iqale ngokuzenzakalelayo "idivayisi yokukhipha indle nesengezo samanzi" lapho izinga lamanzi liwohloka ukuze kuqinisekiswe ukusebenza kahle kokuhwamuka kwefilimu yamanzi kanye nempilo yesevisi yesisetshenziswa.
Incazelo Yemikhiqizo
Ngokombono wezinzuzo zokusebenza zesikhathi eside-, ukulawulwa okunembile kwamafeni namasistimu okufuthwa{1}}emibhoshongweni yokupholisa eyiziyingi evaliwe ngeke nje kuphela kunciphise ukusetshenziswa kwamandla nokusetshenziswa kwemithombo yamanzi kodwa futhi kwandise ukuphila kwesevisi yezinto zokusebenza futhi kunciphise izindleko zokuyilungisa. Ngokwezibalo zedatha yezimboni, uma kuqhathaniswa nemodi evamile "yesiqalo-esilungisiwe{4}}yokumisa", isifutho nesifutho esinokulawula ukuguqulwa kwamaza kunganciphisa ukusetshenziswa kwamandla ngonyaka ngo-30%-40% kanye nokusetshenziswa kwemithombo yamanzi ngo-25%-35%. Ngesikhathi esifanayo, umjikelezo wokuhlanza ikhoyili unwetshwa izikhathi ezingu-2-3, futhi izinga lokuhluleka kwezisetshenziswa zehliswa ngaphezu kuka-50%. Le ndlela yokusebenza "yokonga{16}}yokonga amanzi kanye nokunciphisa ukusetshenziswa" ayihlangabezani nje kuphela nezidingo zokuthuthukiswa "eziluhlaza kanye nekhabhoni ephansi" zemboni yesimanje kodwa futhi iletha izinzuzo ezinkulu zezomnotho emabhizinisini, ibe enye yezikhombisi-ndlela eziyinhloko zokuthuthukiswa kwezinhlelo zokupholisa zezimboni.
