Ithangi Lokugcina Lamanzi Apholile Esikhungweni Sedatha
Ithangi lokugcina lamanzi apholile lihlukanisa i-chiller ekuguquguqukeni komthwalo, linciphisa ukuqala kwe-compressor futhi lihlanganise izikhathi zokuguquka; lilinganisele emaminithini angu-3-15 okusebenza kwe-chiller ku-design delta-T. Sebenzisa ithangi le-atmospheric elineyunithi yokucindezela noma isitsha se-ASME esicindezelwe kuye ngokucindezela kwe-loop, ngokufaka i-insulation ne-glycol lapho kudingeka.
Abaphathi bezikhungo zedatha abahlela amasistimu okupholisa, okuvimbela umlilo kanye namanzi enqubo baqhubeka nokubuza umbuzo oyingqayizivele: yiluphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile ku-"ithangi lokugcina lamanzi apholile lesikhungo sedatha", ihlanganisa ukukhethwa kwethangi lokugcina lamanzi apholile le-DC. Inhloso ukunikeza onjiniyela namathimba okuthenga umbono ocacile, osekelwe emazingeni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olufanele, into kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi Lokugcina Lamanzi Apholile Lenzani
· Lihlukanisa isihlungi emthwalweni. Ithangi lokugcina limunca ukushintshashintsha komthwalo ukuze isihlungi sisebenze isikhathi eside, siqale kancane - sivikela ama-compressor futhi sithuthukisa ukusebenza kahle kwengxenye yomthwalo.
· Lihlinzeka ngesidingo sesikhashana. Ngesikhathi sokukhuphuka noma ukudluliswa kwepompo, ithangi lihlinzeka noma limunca umthamo ngaphandle kokuphazamisa ukuvikelwa kokugeleza okuphansi.
· Ivumela ukulandelana. Ama-chiller amaningi namaphampu ahamba ngokushisa kwe-buffer, hhayi ngesidingo esisheshayo esingaqondile.
Ukulinganisa nokufaka ingcindezi
· Umthetho wesikhathi sokusebenza. Umthamo we-buffer ngokuvamile uhlosela imizuzu engu-3-15 yokusebenza kwe-chiller ku-design delta-T (rho x cp x delta-T); okwengeziwe emithwalweni eguquguqukayo.
· Okucindezelwe kuqhathaniswa nomoya ojwayelekile. Amalophu abandayo avaliwe angasebenzisa i-buffer ecindezelwe (ASME) noma ithangi elinomoya ojwayelekile elineyunithi ehlukile yokucindezela; ukukhetha kuncike kwingcindezi yelophu.
· Ukuvikelwa kwe-glycol nokugwema ukufa. Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukufa; izinto zethangi neze-trim kufanele zihambisane noketshezi.
Izinto Nemigomo
· Okunamekiwe noma i-stainless. Insimbi ebolile nge-epoxy noma i-GFS ehlanganiswe ngamabhawudi, i-stainless, noma insimbi eshiselwe iyafaneleka emsebenzini opholile; i-NSF/ANSI 61 ibalulekile kuphela uma iseduze namanzi okuphuza.
· I-ASME lapho kucindezelwe. Imikhumbi ye-chilled-water noma ye-TES ecindezelwe ingaphansi kwe-ASME BPVC Section VIII; ingcindezi yokuklama nezinga lokushisa kuyacaciswa, akucatshangwa.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation nesivimbelo somhwamuko ukunciphisa ukungena nokujiya emhlabathini we-energy-plant.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 reserve igcinwa ihlukile emanzini okusebenza.
· Ukugcwalisa okupholile. Ukushintshwa kokulahlekelwa okuqhubekayo kwe-tower/humidifier.
· I-Chilled buffer / TES. Ukuhlukanisa nokugcina ukushisa okungekho ngesikhathi sokuphumula.
· Inqubo namanzi okuphuza. Ukudla kwesithimula, ukufaka umswakama, ukuhlanza lapho izinga lihambisana khona.
Ukukhetha nokuqhathanisa
Khetha ngokwezinga lamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboliwe nensimbi eboliwe ene-epoxy zimi ngokushesha ezindaweni eziqinile ze-DC futhi zihlangabezana ne-NSF/ANSI 61 emsebenzini oseduze namanzi okuphuza; insimbi ewelidiwe noma ukhonkolo zifanele izidingo ezinkulu kakhulu noma ezinengcindezi; imikhumbi ye-ASME isebenza kuphela lapho ingcindezi idlula umkhathi. Qinisekisa izitifiketi namaphrojekthi okubhekiselwe kuwo ngaphambi kokunikeza.

Ubungcweti benkampani
I-Center Enamel (Shijiazhuang Zhengzhong Technology Co., Ltd.) ihlinzeka ngamathangi amakhulu okugcina amanzi aboshiwe nashiselwe kanye nemikhumbi yengcindezi ye-ASME, eqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS ne-FM, futhi iletha emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa neplanti yamanzi abandayo yesikhungo sedatha kuwumsebenzi wokuxhumanisa ubunjiniyela okufanele kuqinisekiswe ngokuhambisana nomklamo wokupholisa; le ndatshana iwumhlahlandlela wezobuchwepheshe, hhayi inkomba yephrojekthi.
Imibuzo Evame Ukubuzwa
U: Ithangi le-buffer yamanzi apholile lenza ini?
I: Ihlukanisa isihlanzi emithwalweni yomthwalo ukuze i-compressor isebenze isikhathi eside ngokuqalisa okumbalwa, futhi ihlanganisa izikhathi zoshintsho ngesikhathi sokukhuphuka noma ukudluliswa kwamaphampu ngaphandle kokuphazamisa ukuvikelwa kokuhamba okuphansi.
U: Ngingayilinganisa kanjani ithangi le-buffer yamanzi apholile?
A: Umthetho ojwayelekile uhlosela amaminithi angu-3-15 okusebenza kwe-chiller ku-design delta-T (ivolumu isuka ku-density x specific heat x delta-T); okwengeziwe emithwalweni eguquguqukayo kakhulu.
Umbuzo: Ithangi le-buffer elinengcindezi noma elinomoya?
Impendulo: Umjikelezo opholile ovaliwe ungase usebenzise ithangi elinomoya elinesigaba sokufaka ingcindezi esihlukile, noma isitsha se-ASME esinengcindezi. Ukukhetha kuncike kungcindezi yomjikelezo kanye nomklamo.
Umbuzo: Ingabe amathangi e-buffer apholile adinga i-glycol?
Impendulo: Ezimweni ezibandayo noma zomthwalo ongaphelele ingxube ye-glycol ivimbela ukufika kweqhwa; izinto zethangi nezokuhlobisa kufanele zihambisane noketshezi, futhi kudingeka i-insulation enesivikelo somhwamuko.
Umbuzo: Iyiphi into esetshenziswayo kumathangi e-buffer apholile?
A: Insimbi eboliwe ene-epoxy noma i-GFS, insimbi engagqwali noma ewelidiwe; i-NSF/ANSI 61 kuphela uma iseduze namanzi okuphuza.
U: Yimiphi imigomo esebenzayo?
A: I-AWWA D103-09 (eboliwe) noma i-D100 (ewelidiwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 ngokwesidingo somsebenzi.
Nge "chilled water buffer tank for data center", indlela esebenzayo iwukuthi uqale emsebenzini - izinga lamanzi, ingcindezi, umthamo kanye nesidingo sokuqina - bese uvumela izinga (NFPA 22, AWWA D103-09/D100, ASME BPVC VIII, NSF/ANSI 61) linqume uhlobo lwethangi kanye nempahla. Ukugcinwa kwamanzi esikhungweni sedatha kuyisinqumo sezinhlelo, hhayi ukuthenga impahla; ukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sethangi lokupholisa lesikhungo sedatha, umthamo kanye nokukhethwa kwempahla.
