Ukubikwa Kwe-WUE Ne-PUE Kokusebenza Kahle Kwamanzi: Indlela Amanzi Abuyisiwe Athuthukisa Ngayo Isikolo
I-Water Usage Effectiveness (WUE) kanye ne-Power Usage Effectiveness (PUE) yizilinganiso ezimbili ze-Green Grid ezilinganisa ukusetshenziswa kwezinsiza zedatha-center — i-WUE ihlukanisa isamba sokusetshenziswa kwamanzi endaweni ngonyaka ngamandla kagesi wezinto ze-IT, kanti i-PUE ihlukanisa isamba samandla kagesi wesikhungo ngamandla kagesi wezinto ze-IT. Amanzi abuyiselwe — amanzi emvula anqotshiwe, ukunikezwa kukamasipala okubuyiselwe kanye nokubuyiselwa kwamanzi asetshenzisiwe ezindongeni zokupholisa — ehlisa i-WUE ngoba ithatha indawo yamanzi ompompi enambeni ephezulu ngaphandle kokushintsha inamba ephansi yamandla e-IT, kuyilapho i-PUE ilawulwa wuhlelo oluhlukile lokusebenza kahle kwamandla. Ukubika kokubili ngobuqotho, ngamanzi abuyiselwe abalwa ngendlela efanele, kuvumela umqhubi ukuthi abonise izinzuzo zangempela zokusebenza kahle esikhundleni sokubalwa kwezimali okuhle.
Ukusebenza kahle kwesikhungo sedatha kubikwa ngezinombolo ezimbili abathengi, abasebenza kanye nabalawuli manje abalindele ukuzibona: i-PUE yamandla kanye ne-WUE yamanzi. I-PUE ibilokhu iyisihloko esikhulu iminyaka; i-WUE ikhula ngokushesha njengoba ukushoda kwamanzi kwenza ukusetshenziswa kube udaba olufinyelela ezingeni lebhodi. Lezi zimbili zihlobene kodwa zihlukile, futhi iphutha abasebenza ngalo abalenzayo ukubika i-WUE ngaphandle kokubala amanzi abuyisiwe okufanele kwehlise — noma, okubi kakhulu, ukusho izinzuzo eziyimigilingwane yokubala esikhundleni sokubuyiswa kwangempela. Le ndatshana ichaza i-WUE ne-PUE, ikhombisa ukuthi amanzi abuyisiwe ashintsha kanjani isikolo se-WUE, futhi ibeka inqubo yokubika eqotho ebekezelayo ekuhlolweni.
I-WUE Ne-PUE Yizinkomba Ezimbili ZeGreen Grid
I-WUE ne-PUE yizilinganiso ezijwayelekile ezivela kuThe Green Grid ezilinganisa ukusetshenziswa kwamanzi namandla esikhungo sedatha ngokuqhathanisa namandla asetshenziswa imishini ye-IT, okunikeza isibalo sobukhulu obuqhathanisekayo kuzo zonke izindawo. Ziwulimi lokubika lokusebenza kahle.
· I-PUE (Ukusebenza Kahle Kokusetshenziswa Kwamandla). Amandla ephelele esikhungo ÷ amandla emishini ye-IT. I-PUE engu-1.5 isho ukuthi kukhona amayunithi angu-0.5 amandla engeziwe ngeyunithi ngayinye yamandla e-IT; ukulahleka kokupholisa nokusabalalisa kuyikhuphula ibe ngaphezu kuka-1.0.
· I-WUE (Ukusebenza Kahle Kokusetshenziswa Kwamanzi). Isamba samanzi asetshenziswa endaweni ngonyaka ÷ amandla ezinto ze-IT ngonyaka, kubikwa ngamalitha (noma amagaloni) nge-kWh yomthwalo we-IT.
· Idinomineyitha eyabiwe. Kokubili kusebenzisa amandla ezinto ze-IT, ngakho-ke kuchaza umphumela ofanayo wokubala kusukela kuma-engeli amanzi namandla.
· Isikhathi sokubika. Kokubili kubikwa njengezibalo zonyaka, i-WUE ihlanganisa yonke imithombo yamanzi endaweni ewungenisayo.
I-PUE iphendula "mangakanani amandla ngekhompyutha ngayinye"; i-WUE iphendula "mangakanani amanzi ngekhompyutha ngayinye." Ndawonye zibeka isithombe semithombo yesikhungo.
Isibali Sokubala Se-WUE Sibala Yonke Imithombo Yamanzi
Isibali sokubala se-WUE sibala wonke amanzi asetshenziswa endaweni ngonyaka, futhi sibala yonke imithombo engena endaweni — amapayipi kamasipala, amanzi abuyisiwe, amanzi emvula agcinwe kanye nanoma yimuphi umfudlana obuyisiwe — ngakho-ke indlela la manzi atholakala ngayo, hhayi nje ukuthi angakanani asetshenziswayo, kunquma isikolo esibikiwe. Isibali sokubala yilapho ukubuyiswa kwamanzi kusebenza khona.
Ingxenye ye-WUE | Okubalwayo | Umthelela wokubuyiswa kwamanzi |
Ukuhwamuka | Ukulahleka kwesithombo sokupholisa | Akushintshi ngokubuyiswa |
Ukukhishwa kwamanzi (kuya emseleni) | Kubalwa njengamanzi endawo | Iyasuswa uma isitholakele/isetshenziswe kabusha |
Ukugcwalisa okuyinhloko | Ibalwa njengamanzi esizeni | Kuncishiswa ngokutholakala |
Kuvunyelwe/kuphinde kwatholakala | Ibalwa njengamanzi esizeni | Kususa okuyinhloko kunombolo ophezulu |
Amandla e-IT (isihlukanisi) | Amaseva + isitoreji | Akushintshiwe ukubuyiswa kwamanzi |
Ngoba amanzi abuyisiwe asangena ngokusebenzisa isiza, ahlala esihlukanisini — kodwa adedela umthamo olinganayo wamanzi aphambili obekuzokuba khona futhi. Umphumela wokugcina isihlukanisi esiphansi kanye ne-WUE engcono, inqobo nje uma ukubuyiswa kungokoqobo futhi kukalwa.
Amanzi Abuyisiwe Ehla I-WUE Ngaphandle Kokuthinta I-PUE
Amanzi abuyisiwe — imvula eqoqiwe, ukunikezwa okubuyiselwe kanye nokubuyiswa kwe-blowdown — kuthuthukisa i-WUE ngokunciphisa ukudonswa kwamanzi aphambili esihlukanisini, kuyilapho i-PUE ingathinteki ngoba ukubuyiswa kwamanzi akushintshi amandla esikhungo uma kuqhathaniswa namandla e-IT. Lezi zilinganiso ezimbili zisabela ezinhlelweni ezihlukene.
1. Amanzi emvula abuthiwe. Imvula ena endaweni iyathatha indawo yamanzi aphuma emthanjeni; kusewukuthi "amanzi endawo" kodwa ithatha indawo yevolumu efanayo yamanzi aphuma emthanjeni, okwehlisa inani lilonke.
2. Amanzi kamasipala abuyiselwe. Umthombo ohlukile, ovame ukubekwa phambili ngesikhathi sesomiso, uthatha indawo yamanzi aphuma emthanjeni enanini eliphezulu.
3. Ukubuyiswa kokukhishwa komoya. Ukubuyisela ukukhishwa komoya kwesikhashana sokupholisa emsebenzini kususa lokho kulahleka emseleni futhi kunciphisa ukugcwaliswa.
4. Ukuzimela kwe-PUE. Amandla asetshenziswa ekwelashweni kokubuyiswa ayingxenye yamandla esikhungo futhi asevele esikhaleni se-PUE ngenxa yamandla aphelele; ukubuyiswa kwamanzi akukuhlawulisi ngokukhethekile i-PUE.
Indaba eqotho: amanzi abuyisiwe ayimpumelelo yangempela ye-WUE evela ekuguqulweni kwangempela, okukalwe ngemitha, kwamanzi obekungaba ngamanzi aphuma emthanjeni noma emseleni.
Ukubika Amanzi Abuyisiwe Ngokweqiniso
Ukuze kubikwe i-WUE ngendlela ethembekile, amanzi abuyisiwe kufanele alinganiswe emthonjeni nasekusetshenzisweni kabusha, futhi ukukhishwa kwamanzi omsuka kufanele kubhalwe phansi — hhayi ukucatshangwa — ukuze ukuthuthuka okubikiwe kubonise ukubuyiswa kwangempela hhayi ukugcinwa kwencwadi okuhle. Ukuhlolwa kuyakhula, futhi izimangalo ezingasekelwe aziphili ngaphansi kwako.
· Linganisa ukubuyiswa. Ukuvunwa, amanzi abuyiselwe kanye nokugeleza kokubuyiswa kwe-blowdown kuyalinganiswa ukuze umthamo wamanzi omsuka okhishiwe waziwe, hhayi uqagelwe.
· Bala ukusetshenziswa kabusha. Umthamo obuyiselwe ekwenzeni amanzi okupholisa, ukuchelela noma inqubo uyabhalwa ngokumelene nomsebenzi ewusebenzelayo.
· Hlukanisa izilinganiso. Ukuthuthuka kwe-WUE kubikwa njengokubuyiswa kwamanzi; i-PUE ibikwa ngaphansi kwezenzo zayo zokusebenza kahle kwamandla (ukupholisa mahhala, izinga lokushisa eliphakeme lokuhlinzeka, izitshalo ezisebenza kahle).
· Gwema ukubala kabili. Amanzi abuyisiwe abalwa kunombolo kufanele angaphinde afunwe njengamanzi okwelashwa angaphandle kwesizinda ngaphandle kokusobala.
Ukubika okuqotho kuhlobanisa inombolo ye-WUE nengqalasizinda ebonakalayo — amathangi, ukwelashwa kanye namamitha — umcwaningi wamabhuku angakuqinisekisa.
Isixhumanisi Sokugcina Nokubuyisela Esingemuva Kwesikolo
Ukuthuthukiswa kwe-WUE okuletwa amanzi abuyisiwe kungenzeka kuphela ngoba kukhona isitoreji sasendaweni nokwelashwa ukuze kubanjwe futhi kulungiswe lawo manzi — amathangi okukhulunywa ngawo ku-AWWA D103-09 ne-ISO 28765 ayimpahla ebonakalayo engemuva kwenombolo ebikiwe. Isikolo silandelela insimbi nokufakwa kwezinto, hhayi nje ispredishithi.
· Isitoreji. Amathangi okubutha, okubuyisela kanye nokubuyisela i-blowdown agcina umthamo obuyisiwe ukuze utholakale lapho iluphu yokupholisa idinga ukugcwalisa.
· Ukwelashwa. Ukuhlunga, ukuthambisa kanye nokubulala amagciwane kulungisa amanzi abuyisiwe emsebenzini, kuvikela umbhoshongo kanye nenqubo.
· Ukuhlanganiswa. Umfudlana obuyisiwe uhlangana nokugcwalisa kanye nebhalansi yesimo esiphuthumayo, ngakho-ke kuthuthukisa kokubili i-WUE nokuqina.
· Ukufakwa kwezindwangu. Izindwangu zamathangi (GFS kuya ku-ISO 28765, noma i-epoxy) ezine-NSF/ANSI 61 noma i-WRAS yokwamukela zigcina amanzi abuyisiwe efanele umsebenzi oseduze namanzi okuphuza.
Ngakho-ke ukutholakala kwe-WUE okubikiwe kufanele kuhambisane nohlelo olubonakalayo lokubuyisa amanzi — amathangi, ukwelashwa namamitha — umsebenzi angakwazi ukukhomba kukho.
Ukuhambisana Kwezinga Namandla Enkampani
Leli sihloko siwumhlahlandlela wezindinganiso/weziqondiso hhayi isicaphuno sephrojekthi; akukho cala eliqanjiwe elivezwayo. I-Center Enamel ihlinzeka ngemikhumbi yokugcina nokubuyisela eyenza ukuthuthukiswa kwe-WUE yesikhungo sedatha kube ngokoqobo futhi kuhlolwe — amathangi amanzi agaywe kabusha, amathangi amanzi anqotshiwe kanye namathangi okubuyisela i-blowdown okubhekiselwe ku-AWWA D103-09 kanye ne-ISO 28765, ngezindwangu ezinesitifiketi se-NSF/ANSI 61 kanye nokwamukelwa kwe-WRAS lapho umsebenzi udinga ukuthintana eduze namanzi okuphuza. Ukwenziwa kwesakhiwo kubhekiselwe ku-EN 1090 yokumaka kwe-CE, futhi amathangi aklanyelwe isisekelo sokuzamazama komhlaba nomoya sendawo (ASCE 7 noma EN 1991/EN 1998). Ukwakhiwa kwe-GFS kwenkampani — ukoqweqwe olushiswe ku-820–930 °C, ukujiya okungu-0.25–0.45 mm, ukunamathela okungaphezu kuka-3,450 N/cm², ukuhlolwa kwe-spark kwe-1,500 V DC ngephaneli ngayinye — kunikeza isitoreji esiqinile, esidinga ukunakekelwa okuphansi semithombo yamanzi abuyisiwe. I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) ikhiqize amathangi aboshiwe kusukela ngo-2008, inamalungelo obunikazi acishe abe ngu-200 ahlobene nokoqweqwe, iqedela amaphrojekthi afakiwe angaphezu kuka-30,000, futhi ihlinzeka ngamathangi angawodwa afinyelela ku-60,000 m³ ngaphansi kokukhiqizwa kwe-ISO 9001 kanye ne-ISO 45001.
Amandla Obunjiniyela Be-Center Enamel
UCenter Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd) isungule futhi yakha amathangi okugcina anezikulufu kusukela ngo-2008. Njengomkhiqizi wokuqala wamathangi ensimbi ehlanganiswe nengilazi (GFS) eChina, inkampani inamalungelo obunikazi acishe abe ngu-200 ahlobene ne-enamel, ikhiqiza cishe amapuleti ensimbi ane-enamel angu-300,000 ngonyaka, isiqedile amaphrojekthi afakiwe angaphezu kuka-30,000 futhi ihlinzeka ngamathangi ayo emazweni angaphezu kwe-100. Isizinda esisha sokukhiqiza esingu-150,000 m² sengezwe ukukhulisa umthamo wokukhiqiza, futhi amathangi angawodwa ahlinzekwa afinyelela ku-60,000 m³. Ukukhiqiza kusebenza ngaphansi kwe-ISO 9001 ne-ISO 45001, ngesitifiketi somkhiqizo esihlanganisa i-NSF/ANSI 61, i-WRAS, i-FDA, i-LFGB, i-CE (EN 1090), i-ISO 28765, i-FM, i-BSCI ne-EUROCODE, futhi ukuklama kubhekiselwa ku-AWWA D103-09, i-ISO 28765, i-NSF/ANSI 61 ne-EN 1090 lapho isicelo sidinga khona.
Imibuzo Evame Ukubuzwa
Umbuzo 1: Uyini umehluko phakathi kwe-WUE ne-PUE?
A1: I-PUE iwukusetshenziswa kwephelele kwamandla esikhungo ÷ amandla e-IT (ubukhulu bamandla); i-WUE iwukusetshenziswa kwamanzi ephelele endaweni ngonyaka ÷ amandla e-IT (ubukhulu bamanzi). Zombili zisebenzisa amandla e-IT njengesihlukanisi kodwa zikala izinsiza ezihlukene.
Q2: Ingabe amanzi abuyisiwe athuthukisa kanjani i-WUE?
A2: Amanzi abuyisiwe (avunyelwe, alungisiwe, ukubuyiswa kwe-blowdown) asusa umthamo olinganayo wamanzi aphambili kunombolo yamanzi endaweni, okwehlisa isamba samanzi endaweni nge-kWh yomthwalo we-IT.
Umbuzo 3: Ingabe ukubuyiswa kwamanzi kushintsha i-PUE?
A3: Hhayi ngokuqondile. I-PUE ibonisa amandla esikhungo esiphelele uma kuqhathaniswa namandla e-IT; amandla asetshenziselwa ukwelashwa kokubuyiswa asevele eyingxenye yamandla esikhungo, ngakho-ke ukubuyiswa kwamanzi kuyisenzo se-WUE, hhayi se-PUE.
Umbuzo 4: I-WUE ibikwa kanjani?
Impendulo 4: Njengokusetshenziswa kwamanzi esizeni sonke ngonyaka kuhlukaniswe ngamandla kagesi ezinto zekhompyutha ngonyaka, ngamalitha noma ngamagaloni nge-kWh. Yonke imithombo yamanzi engena esizeni ibalwa kunombolo ophezulu.
Umbuzo 5: Ubika kanjani amanzi atholakele ngobuqotho?
Impendulo 5: Linganisa ukuhamba kokutholakala nokusetshenziswa kabusha, bhala ukuncishiswa kokuqala, gcina ukuthuthukiswa kwe-WUE ne-PUE kuhlukene, futhi ugweme ukubala kabili — ukuxhumanisa inombolo namathangi angokoqobo nokwelashwa.
Umbuzo 6: Ingabe amanzi atholakele adinga isitifiketi sokuphuza?
Impendulo 6: Lapho amanzi atholakele aseduze namanzi okuphuza noma angaxhumana ngokunqamulelayo, izindwangu zithwala ukwamukelwa kwe-NSF/ANSI 61 noma i-WRAS; umsebenzi womlilo nowenkqubo ucacisa indwangu efanele yamanzi.
Umbuzo 7: Yisiphi isilinganiso sethangi esisebenza ekugcinweni kokutholakala?
A7: Amathangi okubuyisela aboshwe ngezibulongo abhekiselwa ku-AWWA D103-09 kanye ne-ISO 28765, kanye ne-EN 1090 yokusebenza kwe-CE kanye nokwamukelwa kwe-lining (NSF/ANSI 61, WRAS) okuhambisana nomsebenzi wamanzi abuyisiwe.
I-WUE ne-PUE yizinkomba ezimbili ze-Green Grid ezihlola ukusetshenziswa kwamanzi namandla esikhungo sedatha uma kuqhathaniswa nomkhiqizo we-IT, futhi ziphendula imibuzo ehlukene: i-PUE yamandla, i-WUE yamanzi. Amanzi abuyiselwe — imvula eqoqiwe, ukunikezwa okusetshenzisiwe kabusha kanye nokubuyiswa kwe-blowdown — ehlisa i-WUE ngokuthatha indawo yamanzi aphuma emthanjeni omkhulu enambeni ngaphandle kokuthinta i-PUE, inqobo nje uma ukubuyiswa kukalwa, kubhalwe phansi futhi kubikwe ngokweqiniso. Ukuthuthuka kungokoqobo kuphela ngoba isitoreji sasendaweni nokwelashwa okubhekiselwe ku-AWWA D103-09 ne-ISO 28765 kukhona ukuze kubambe futhi kulungise lawo manzi. Bika ukubuyiswa ngobufakazi obuphathekayo, gcina lezi zinkomba ezimbili zihlukene, futhi inzuzo ye-WUE iyavikeleka kunokuba ibe umhlobiso nje.
Khuluma Nonjiniyela
Ukuze kuthuthukiswe i-WUE yesikhungo sedatha ngokubuyiswa kwamanzi, sithumele i-WUE ne-PUE baseline yamanje, izinga lokugcwalisa nokukhipha ukuhlanzwa kokupholisa, imithombo etholakalayo yokubuyiswa (ukuvuna, amanzi avuselelwe, ukukhipha ukuhlanzwa), imisebenzi yokusetshenziswa kabusha, kanye nezitifiketi ezidingekayo (AWWA D103-09, ISO 28765, NSF/ANSI 61, WRAS, CE-EN1090). Sizobuyisela incazelo yokugcina yokubuyiswa enomthamo, ukwamukelwa kwe-lining kanye nokuhlolwa kokuzamazama komhlaba nomoya okwenziwe ngokwesisekelo se-ASCE 7 noma i-EN 1998 esebenzayo, kulinganiswe ngokulingana nomgomo we-WUE owubikayo.
