FFU vs AHU kubhobho lokuchitha

Ukuphatha Komoya Ngokuhle Kunye Nokuzimisela Kwi-ISO (ISO 5–8)

Ukuphatha komoya okuphelele kubhizinisi eziqondile zesi-ISO 5–8 kubalulekile ukuthi kuzimiselwe ngokuphelele ngokufiltra nokuphatha komoya ukuze kuzimiselwe ngokuphelele ngokwesi-ISO 14644-1. Uma kubhekwa i-FFU ne-AHU, ukukhetha phakathi kwezinhlobo zokuphatha komoya ngokwezindawo nezinhlobo zokuphatha ngokwezinkampani ziyathinta ngqo ukuthi kuyaphila ukuthi kubhekwe phakathi kwemithombo yezinye zokufiltra.

Ukuphelele Kwokufiltra Ngokuphelele (HEPA/ULPA) Kunye Nokuphatha Komoya Ngokwezindawo

Amafiltara ase-HEPA angathwala amaphakathi aphezulu kwe-99.97 percent apho amandla amancane kakhulu kwe-0.3 microns. Amafiltara ase-ULPA ayagcina ngaphezulu, akhuthaza amandla aphezulu kwe-99.999 percent apho amandla amancane kakhulu kwe-0.12 microns. Izinhlangano zase-FFU zinikela ukufiltara lapho kuluncedile kakhulu, okuyisivumelwano sokuphatha izikhungo zokugcina futhi kusiza ekubambeni imithombo yase-ISO 5 emazinkundleni apho ukuchitha kuyisifunda esiphambili, njengoba kuzokwenza umsebenzi wokwenza izinto ezilungile kahle. Ngaphakathi kwesinye isikhathi, izinhlangano zase-AHU zihlukene ngokusebenzisa izibhanki zemafiltara e-HEPA noma e-ULPA ezincane, kodwa lezi zinhlangano zinamaphroblemi awo. I-d ductwork ingayabhekwa ngamaphakathi kanye ngezinsuku, futhi izinguquko zempilo yomoya kuzo zonke izinhlangano ziyasiza ukuthi izinto ezingavumelekile zingene. Ngokulandela iziripholi zasezindustria, izindawo ezenza izinhlangano zase-FFU zibona ukuthi kunezinto ezingavumelekile zezomoya ezingu-30 kuze ne-50 percent engaphezulu kwezindawo zase-ISO 5 zokuchitha uma zihambaniswa nezindawo ezenza izinhlangano zase-AHU. Lokhu kuyisidingo esikhulu ekubambeni ukuchitha kwezindawo zokwenza izinto ezilungile kahle noma emazinkundleni apho ukuchitha kuyisifunda esiphambili. Kananjalo, ubunye bokubambana kwezinhlangano zase-FFU kusiza ekubambeni umoya lapho kuluncedile ngaphandle kokuzwa ngokuthi kungabikho ukuthwala kwezinto ezingavumelekile phakathi kwezinkundla ezahlukene kwezindawo.

Izikhathi Zokushintsha Kwe-Atmosphere, Ukulinganiswa, nokulandela i-ISO 14644-1 Ngokweqiniso

Izinga le-ISO 14644-1 libeka lokho esikubiza ngokuthi amanani aphansi okushintsha komoya. Ngokwesibonelo, izindawo ze-ISO 5 zidinga ukushintshwa komoya okungu-250 kuya ku-300 ngehora ukuze nje kuhlale kunenani lezinhlayiyana elingaphansi kuka-3 520 ngomitha oyisikubhu noma ngaphezu kuka-0.5 microns. Kukhona ne-ISO 7 edinga izinguquko ezingaba ngu-60 ngehora ukuze ihlale ngaphansi kwezinhlayiya ezingu-352,000 ngemitha eyisikubhu. Uma kuziwa ekulondolozeni lolu hlobo lwendawo ehlanzekile, ama-FFU array akhanya ngempela. Lawo ma-unit akhiqiza lokho okwaziwa ngokuthi ukugeleza okufana ne-laminar okuhambisana nama-95% emibhalweni yokugeleza komoya, okwenza afaneleke ngokukhethekile ukuhlangabezana namazinga e-ISO 5 kuya ku-6. Ngakolunye uhlangothi, izinhlelo ze-AHU zendabuko zibhekana nezinselele ngoba zincike emoyeni wokuphakelayo. Lokhu kulungiselelwa kuvame ukudala izinkinga zokudideka kanye nokulahleka kwengcindezi okungaguquguquki okuphazamisa ukufana kokusabalalisa komoya, okuphawuleka ngokukhethekile kulezo zindawo ze-ISO 7 kuya ku-8 lapho izimfuneko zokuhlanzeka zingekho ngokuqinile kodwa zisabalulekile. Nakuba ama-AHU ehlangabezana nezidingo zokuhlukanisa uma elinganiswe kahle, ama-FFU ngokwemvelo anikeza ukulawula okungcono kokusabalalisa izinhlayiya ezindaweni ezibucayi. Lokhu kusho ukuthi asisekho esincike ezinkambisweni eziyinkimbinkimbi zokuqalisa ukusebenza, okudinga isikhathi nezinsiza ukuze zisetshenziswe kahle.

Ukubalwa Kwemithambo Yezinhlelo: Ukugxila, Ukuphatha, nokuthi Kukhona Isibopho Sokungena Kwemithambo Kwe-FFU Nase-AHU

Ukufilta Kuphakathi Kwesikhundla (FFU) vs Ukuphatha Kwesikhundla Esikodwa (AHU): Imiphumela Yempilo Yesifuba Nokulungisa Ukungena Kwemithambo Ngaphansi Kwesikhundla

Ama-FFU ahlinzeka ngokuhlunga kwe-HEPA noma kwe-ULPA ezingeni ngqo kumamojula wesilingi ngamanye, okudala lezo zindawo ezinamandla eziqinile ezidingekayo ezindaweni zokusebenza ezibalulekile. Ngokuyinhloko, lokhu kulungiselelwa kuvimbela izinhlayiya ukuba zingangeni lapho zingekho khona. Okwenza la manani abe akhethekile ukuzimela kwawo - uma elinye lingaphumeleli, amanye aqhubeka esebenza ngaphandle kokulimala. Ngaphezu kwalokho, asikho isidingo semisele engase isakaze ukungcola. Ukugeleza komoya okuvela emgqeni we-FFU kugcina izimo ze-laminar ezinokudideka okuncane kakhulu, okusho ukuthi izinhlayiya zihlala zimile emoyeni isikhathi esifushane. Ngokwezifundo zamuva nje ezihlola ukusebenza kwezikhungo, ukushintshela ekuhlolweni kwe-FFU endaweni yokusetshenziswa kunganciphisa izinkinga zokungcola cishe ngamaphesenti angu-40 uma kuqhathaniswa nezinhlelo zendabuko ezinezimbobo.

Ukwehla, Ukuguquguquka Kokuthuthukisa, Nokulungiswa Kokusetha

Ukuthi i-FFU systems ziyenziwe ngamaphakathi kuyavumela abasebenzisi basecleanroom ukuguqula indawo yabo yokusebenza ngokushesha kakhulu ngaphandle kokukhupha amagqabi noma ukwenza umsebenzi omkhulu wokwakha. Lokhu kuyenza lezi zinhlobo zokusebenza zibhekene kakhulu nezindawo zokuzilonda apho izindlela zisemthethweni noma uma izindlela zokuproducwa ziyaguqula kusukela. Ukubheka kahle kukuthi izinhlobo ezinye ziyaguqulwa kuphela, ziyakhiwa futhi ziyabhalwa emva kuleli ndawo lapho kufanele bafanele ngokuhambisana nokugcina kwemithombo. Akukho zindawo ezingazihlukaniswa ngokuphambuka kwe-airflow okunqofa kakhulu ngezindlela zokusebenza zika-AHU zokugcina. I-FFU eziningi zifaka kwi-grid zokuphakama kwezindawo zokuphakama ngaphandle kokunqoba kwezindlela zokufaka, okuyavumela ukuthi isikhundla esingaphezulu sisebenze kakhulu. Lokhu kubaluleke kakhulu kwezindawo ezidala ekufuneka zihlelwe. Izincazelo zezindustria zibonisa ukuthi izimpahla ziyathola phakathi kwe-25% kanye ne-60% emsithilini wokuhlela ngokulinganisa nokubusa i-AHU systems. Ngaphezu kwalokho, uma kunezidingo zokuvutha ku-ISO classification eyinkulu kusukela, i-FFUs zivumela lezi zidingo zihlanganiswe ngaphandle kokukhupha konke futhi ukusuka kusukela.

Ukusebenzisa i-Energy, I-Isilinganiso Sesilinganiso Sesilinganiso, Nokusebenza Kwezinsizakwane Zokusebenza

Ukuhamba Kwamafan, Ukuphatha Kwesitayile Phresha, Nokuhlanganisa Kwesilinganiso Sesilinganiso Sesilinganiso

Inani lamandla adingekayo ukuze umoya udlule egumbini elihlanzekile (elilinganiswa ngama-watt nge-CFM ngayinye) lidlala indima enkulu ekutheni amandla asetshenziswa kangakanani. Ama-Fan Filter Units asebenza ngezidingo eziphansi kakhulu zengcindezi ye-static cishe ama-intshi angu-0.5 amanzi ngenxa yokwakhiwa kwawo kwe-EC motor. Lokhu kugwema ukulahlekelwa kwamashubhu okuhambisana nama-Air Handling Unit avamile. Ama-AHU amaningi adinga amanzi angaphezu kuka-2 inches ukuze nje aqhube umoya ngemigudu ehlungiwe ye-HEPA. Nakuba ama-AHU enenzuzo uma kuziwa ekulawuleni izinga lokushisa kuyo yonke indawo, ama-FFU anciphisa izinkinga zokuvuza kwezinduku futhi avumela opharetha ukuba balungise ngokuqondile ukugeleza komoya ezindaweni ezihlukahlukene. Lapho kubhekwa izindleko zokuphila, ucwaningo lukhombisa ukuthi ama-FFU angonga cishe u-23% wamandla we-fan emakamelweni ahlanzekile e-ISO 7 ngokuya ngemihlahlandlela yakamuva ye-ASHRAE kusukela ngo-2023. Lokhu konga kanye nokugcinwa okulula kanye nokuvumelana nezimo okungcono ekusetshenzisweni kwemali kwenza ama-FFU abe ukukhetha okuqinile kokusebenza okuzinzile ezindaweni eziningi ezihlanzekile namuhla.

Ukugcina Kwe-Design ne-Strategy Yokuhambisana Kwamafutha

Izihlombe Zama-FFU Zokufakwa Emhlabathini vs Isiphumo Se-AHU Esifakwa Ngemithambo: Ukubuyisela Kwesikhathi Sekulaminare Nokuphatha Kwesibhubhu

Ukufaka ama-FFU arrays ophahleni kusiza ngempela ukugcina ukugeleza komoya okuyi-laminary ngoba la madivayisi abeka izihlungi ze-HEPA noma ze-ULPA lapho zidingeka khona kakhulu. Lokhu kulungiselelwa kunciphisa lezo ziphithiphithi zomoya ezicasulayo ezibangelwa ukugoba kwezimbobo, ama-diffuser enza izinto zibe zimbi, nezinguquko ezingalindelekile zengcindezi ezivamile ezinhlelweni ze-AHU zendabuko. Umqondo wonke usebenza kangcono ngoba izinhlayiya aziphazanyiswa kakhulu, futhi uhlelo luhambisana kahle nezindawo zokusebenzela uma lufakwe kahle. Yebo, ama-AHU nawo angadala izimo eziyinkimbinkimbi uma sifaka imodeli yekhompyutha, ama-dampper akhethekile namadivayisi alungisa ukugeleza komoya, kodwa ake sibhekane nakho - lezi zinhlelo ezindala zisalwa nezindawo ezifile nokugeleza okuhlanekezelwe, ikakhulukazi lapho zizama ukufakwa ez Ngokwezindinganiso ze-ISO 14644 ukuhamba ngezinhlelo ze-FFU kwenza ukuphila kube lula ngezinjongo zokulandela umthetho ngoba ngokwemvelo kukhiqiza ukugeleza komoya okuqhubekayo kusuka ophahleni kuya phansi ngaphandle kokudinga zonke izinhlobo zokulungiswa okuyinkimbinkimbi kwezinkinga zokugeleza komoya.
