Umbuzo wokuthi Yini i-Purification Air Handling Unit (PAHU)? Kufunda njani?

Ukuhlaziywa

I-Purification AHU i-PAHU yisikhundla esihlelwe kahle sokusebenza kwamafanisi wehlanzela, esihlelwe kahle kumathuluzi wekhalimha. Ngaphezu kwezinhlangano zokulawula iklima (isilinganiso sesithembu nesihlukahlukana sesihlukahlukana), kubalulekile ukulawula ukuchitha kwamafanisi (isilinganiso semaphakathi), isihlukahlukana sesiphakathi, nokuvuka kwamafanisi. Kuyasebenza kumathuluzi amakhulu njengezindlu zokusebenza zezimpilo, izindlu zokuphatha izimpilo, izindlu zokuhlukanisa izimpilo, nezindlu zokufunda i-PCR. Ngokusebenzisa izifiltara ezahlukeneyo nokulawula ngokucophelela isiphakathi, kusinika amafanisi amahle ngokutshona ngokuphambuka kwezinkambo zokuphambuka okuhle noma okubi ukuze kungavunyelwe ukugxilwa kwezinye izinto.

Amaphakathi Nokuthi Yini Okuhle

Ngokulingana nezinkambo zokusebenza kwehlanzela ezingenabizo, i-Purification AHU iyinkambo enkhulu:

IHLOBO LESIFAN

• Usebenzisa amafanisi e-Variable Frequency Drive (VFD) ukuthola umphumela wokusebenza kanye nokulawula ngokucophelela ukuvuka kwamafanisi.
• Kudinga isiphakathi esiphezulu ukuze kubhekwe isibonelo sokubhekwa ngamafiltara amahle.

Amaphakathi Okufiltara

• Ifiltara Yesibonelo (G4/F5): Iyaphatha izinto ezingaphezulu (ubhubesi, izihlathi) ukuze isikhombise izinye iziqephu.
• Ifiltara Yemidli (F7/F8): Iyaphatha izinto ezingaphansi futhi iyahlela ukuphakamisa ubude bokusebenza kwamafiltara ayo aphakeme aye-High Efficiency Particulate Air (HEPA).
• Ifiltara ye-HEPA (H13/H14): Indawo yokuqhubeka kwekukhuluma. Ngokuvamile iyasetshenziswa emuva futhi iyavumela umoya ufake ku-ISO Class 5 noma kungenye ngokuphelele kokuchitha.

Izinqakamba Zokulingana Kwesikhathi Nokulingana Kwesikhathi Sokushisa

• Amacoil Eshisa/Okushisa: Sebenzisa amanzi amhlophe noma amanzi amhlophe kakhulu noma ukususa ngqo ukuze kuhlanganiswe isikhathi futhi kususwe umsindo.
• Ukufaka umsindo: Sebenzisa umsindo omhlophe wokushisa, umthwalo wokushisa noma amashini okushisa. Lezi zindlela zisebenziswa emazinkhosini ngoba ziyisikhumbuzo futhi zinakeka ukuthi izibhakathini zizofika.

Ukugcina nokulingana Kwezivimba

• Iboks Yokugcina: Iyabringa umoya wendawo yokuph outside ukuze kubhekwe umoya wokusha futhi ukuthi kwenzeke umoya wokusha wokuphambuka ngokuphelele, futhi umoya wokubuyela owaphathwe uyagcinwa ukuze kubhekwe ukuthi kungena kwezimali.
• Amasiliyense: Ayancima umsindo wesikhathi sokuphambuka kwezinye nezinye zezifanayo futhi amafani ukuze kubhekwe izimali zokuncima umsindo emazinkhosini.

Umkhathaliso wokubhala

• Izinhlangano ze-DDC/PLC: Zizokhombisa ngokuzenzakalela izisensori ukuze zihlele isikhathi se-VFD, ukugcina izihlukanisi zempilo (njengokuphakamisa impilo kwi-ORs ukuze kubhekwe amasimbi; ukuphepha impilo kwi-PCR labs ukuze kubhekwe izithombe).
• Amazwi okuhlonipha impilo yokuqondana: Ayabiza abasebenzi lapho izifiltela zibhujwe futhi zidinga ukubuyiselwa.

Umgangatho wokusebenza kumlinganiso wokuhlala kwesihlangu sasekhaya.

• Ukukhula kwezinye zempilo: Impilo entsha neyokubuyela kufundwa kusuka kwezinhlangano.
• Ukuchaza kabusha: Impilo ihamba ngama-filtela we-G4 ne-F7 ukuze kususwane izinkambo zezinto ezinkulu.
• Ukuchaza: Impilo ihlukunyezwa/ngekhanda futhi ikhululekile ukuze ibe nempilo yendlela eyodwa.
• Ukuchaza okugcwele: I-fan iyadonsa impilo ngama-filtela we-HEPA, ukwenza yena isihlangu futhi isilungile.
• Ukudistributeka: Impilo esihlangu siya kuma-ducts owenziwe ngokulinganisekile ukuze kufike kuma-diffusers asekhaya.
• Ukugcina kwezinye zempilo: Impilo iforma i-laminar (eyodwa) noma i-turbulent ukuze kususwane nokubhujwa kwezinto ezingavumelekile kumkhaya.
• Ukubhala/Ukubuyela: Isilwane sibhala ngamaphoyinti esikhundleni sokugcina emzini, isiqhelo esinye sibuyelwa kabusha, kodwa isiqhelo esingapheli sibhalwa ukuze kubalwe ubukhulu.

AHU vs. FFU vs. AHU Yendlela Yokuqonda

Isiphetho

I-AHU yokuhlanzeka yisiphambano esikhulu se-engineering yezindawo zokuhlanya ezihlukile kwezihospitali. Ngokugcina ukuthi kubhekwa kwezifiltara ezihle kanye nokuphatha okuzenzakalelayo kwezinqumo zokuphakama nokwekukhala, kwenza indawo encane enesibonelo sokuhlanya esihle esingahlanganisi ekuphatheni amadoda abe nesibindi futhi esingahlanganisi ekuphatheni izindlela zokusebenza zemithambo.

Imibuzo Evame Ukubuzwa

I-AHU yokuhlanzeka yiyiphi?

I-AHU yokuhlanzeka isebenza ngamafan ezinkulu zokuphakama kanye nezifiltara ezintathu (G4, F7, kanye ne-HEPA) ukuhlanza isikhathi, ubunzima bezinye nezinqumo zokuphakama kwezindawo zokuhlanya.

Ukufiltara kusebenza kanjani?

Kunezinhlobo ezintathu zokulondoloza apho izifiltara zokuphela (G4/F5) nezifiltara zokudala (F7/F8) zilondolozela ikhore yase-HEPA (H13/H14), futhi zisusa izinto ezingaphansi nezibhaktiria ukuze zifikelele emaqhingini ase-ISO 5.

Kungani ukuphatha kwezinqumo zokuphakama kubalulekile?

Ukuphatha okuphelele kwezinqumo zokuphakama kususa ukuthi kubhekwe kwezinye izindawo ngokuphakama okuphelele ukuze kususwe izibhaktiria kuma-room yokuqhubeka kwezimithambo, kanye nokuphakama okungaphelele ukuze kususwe izibhaktiria kuma-lab yase-PCR.

Ukuchaza kwezinye kusebenza kanjani?

Isilwane esisile sifuna ngemikhumbi yasezulu futhi sibhala amasiko ekuseni kumikhumbi yasezansi, okwenza umsebenzi wokufusha okuphakathi okuphakathi okuphakathi okuhlela isilwane esihle.
