Kwadalwa ngo Ngokwamukisa
ithangi le-buffer yamanzi apholile yesikhungo sedatha
Ithangi le-buffer yamanzi apholile lihlukanisa isihlungi emithwalweni yokuguquguquka, linciphisa ukuqala kwe-compressor futhi lihlanganise izikhathi zokushintsha; lilinganise ukuthi lisebenze amaminithi angu-3-15 ekusebenzeni kwesihlungi nge-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, okuvikela umlilo kanye namanzi enqubo baqhubeka nokubuza umbuzo oyedwa ongokoqobo: yiluphi ithangi lokugcina elidingekayo kulo msebenzi, futhi linqunywa kanjani? Le ndatshana igxile ku-"ithangi lokugcina lamanzi abandayo esikhungo sedatha", ihlanganisa ithangi lokugcina lamanzi abandayo esikhungo sedatha. Inhloso ukunikeza onjiniyela kanye namathimba okuthenga umbono ocacile, osekelwe ezindinganisweni - hhayi inkulumo yokuthengisa - ukuze kukhethwe uhlobo lwethangi olulungile, into yokwakha kanye nomthamo womsebenzi wangempela.
Incazelo Yezobuchwepheshe
Ithangi Lokugcina Lamanzi Abandayo Lenzani
· Lihlukanisa isihlungi emthwalweni. Ithangi lokugcina limunca ukushintshashintsha komthwalo ukuze isihlungi sisebenze isikhathi eside, siqale izikhathi ezimbalwa - kuvikela ama-compressor futhi kuthuthukisa ukusebenza kahle kwengxenye yomthwalo.
· Lihlinzeka ngesidingo sesikhashana. Ngesikhathi sokwenyuka noma ukudluliswa kwepompo, ithangi linikeza noma limunca umthamo ngaphandle kokuphazamisa ukuvikelwa kokugeleza okuphansi.
· Lenza ukulandelana. Ama-chiller amaningi namapompo ahlelwa ngezinga lokushisa kwethangi lokugcina, hhayi ngesidingo esiguquguqukayo sanjalo.
Ukulinganisa nokufaka umfutho
· Umthetho wokulinganisa wesikhathi sokusebenza. Umthamo we-buffer uvame ukuhlosela imizuzu engu-3-15 yokusebenza kwe-chiller ku-design delta-T (rho x cp x delta-T); okwengeziwe kwimithwalo eguquguqukayo.
· Ukucindezelwa kuqhathaniswa nomoya ojwayelekile. Amalophu abandayo avaliwe angasebenzisa i-buffer ecindezelwe (ASME) noma ithangi lomoya elinophiko oluhlukile lokucindezela; 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 Zokwakha Namazinga
· Okunamekwe noma i-stainless. Insimbi ebolile ene-epoxy noma i-GFS ehlanganisiwe, i-stainless, noma insimbi ebolile 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 Isigaba VIII; ingcindezi yokuklama nezinga lokushisa kucacisiwe, akucatshangwa.
· Ukufakwa kwe-insulation. Amathangi apholile adinga i-insulation nesivimbelo somhwamuko ukunciphisa ukwanda nokujiya emhlabathini wemboni yamandla.
Izimo Zokusetshenziswa
· Ukuvikelwa komlilo. I-NFPA 22 reserve igcinwa ihlukile emanzini okusebenza.
· Ukugcwalisa okupholile. Ukushintshwa kokulahleka okuqhubekayo kwe-tower/humidifier.
· I-Chilled buffer / TES. Ukuhlukanisa kanye nokugcina ukushisa kwe-off-peak.
· Inqubo kanye namanzi okuphuza. Ukudla kwesithimela, ukufaka umswakama, ukugeza lapho izinga lihambisana khona.
Ukukhetha nokuqhathanisa
Khetha ngokwezinga lempilo yamanzi, ingcindezi kanye nesidingo sokuqina esikhundleni sombhalo. I-GFS eboshiwe kanye nensimbi ehlanganiswe nge-epoxy yakha ngokushesha ezindaweni eziqinile ze-DC futhi ihlangabezana ne-NSF/ANSI 61 yomsebenzi oseduze namanzi okuphuza; insimbi eshiselwe noma ukhonkolo kufaneleka 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 nashisisiwe kanye nemikhumbi yengcindezi ye-ASME, eqinisekisiwe nge-ISO 9001, ISO 45001, NSF/ANSI 61, EN 1090/CE, WRAS kanye ne-FM, nokulethwa emazweni angaphezu kwe-100. Ukuhlanganiswa kokugcina ukushisa nesitshalo samanzi abandayo sesikhungo sedatha kungumsebenzi wokuxhumanisa ubunjiniyela okufanele kuqinisekiswe ngokuhambisana nomklamo wokupholisa; le ndatshana iwumhlahlandlela wezobuchwepheshe, hhayi inkomba yephrojekthi.
Imibuzo Evame Ukubuzwa
U: Yini eyenziwa ithangi le-buffer yamanzi apholile?
I: Ihlukanisa isihlanzi emishini yokushintsha komthwalo ukuze i-compressor isebenze isikhathi eside ngokuqalisa okumbalwa, futhi ihlanganisa izikhathi zokushintsha ngesikhathi sokukhuphuka noma ukudluliswa kwamaphampu ngaphandle kokuphazamisa ukuvikelwa kokugeleza okuphansi.
U: Ngingayilinganisa kanjani ithangi le-buffer yamanzi apholile?
A: Umthetho ojwayelekile uhlosela amaminithi angu-3-15 okusebenza kwesihlungi esisebenza nge-design delta-T (ivolumu isuka ku-density x specific heat x delta-T); okwengeziwe emithwalweni eguquguqukayo kakhulu.
Umbuzo: Ithangi le-buffer elinomfutho noma elingenawo umfutho?
Impendulo: I-loop epholile evaliwe ingase isebenzise ithangi elingenawo umfutho elinesigaba sokufaka umfutho esihlukile, noma isitsha se-ASME esinomfutho. Ukukhetha kuncike kumfutho we-loop 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 nezokulungisa kufanele zihambisane noketshezi, futhi kudingeka i-insulation ene-vapor barrier.
Umbuzo: Iyiphi into esetshenziswayo kumathangi e-buffer apholile?
Impendulo: Insimbi eboliwe nge-epoxy noma i-GFS ehlanganisiwe, insimbi engagqwali noma insimbi eshiselwe; i-NSF/ANSI 61 kuphela uma iseduze namanzi okuphuza.
Umbuzo: Yimiphi imigomo esebenzayo?
Impendulo: I-AWWA D103-09 (eboshiwe) noma i-D100 (eshiselwe); i-ASME BPVC VIII uma inengcindezi; i-NSF/ANSI 61, i-EN 1090/CE, i-ISO 9001/45001 njengoba umsebenzi udinga.
Kuma-“ithangi lokugcina amanzi abandayo esikhungo sedatha”, indlela esebenzayo iwukuqala 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 nje; ukukucacisa kahle kusenesikhathi kuvikela kokubili isikhathi sokusebenza kanye nempilo yeminyaka eyi-10-15 yesikhungo.
Xhumana nonjiniyela ukuze uxoxe ngesicaciso sethangi lokupholisa, lokugcwalisa noma lokugcina ukushisa kwesikhungo sakho sedatha, umthamo kanye nokukhethwa kwempahla.
