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

Ukuhlaziywa

I-Purification AHU (PAHU) yiyunithi eyasemthethweni yokuqondisa amafutha, eyadlulwa ngokupheleleyo kumaziko okuhlanzwa kwamafutha. Ngaphezu kwezinhlayiseko zokuphatha ukukhanya (isikhathi nesihlangu), kubalulekile ukuphatha ukukhanya kwezifutha (ukulinganisa izinkumbulo), ukuchaphaza kwezinqambu, nokuvula kwezifutha. Yidala ngokupheleleyo kumaziko amakhulu njenge- Amaphoyinti wokusebenza kwezihospitali , Amaphoyinti wokugcina isibindi , Amaphoyinti okuhlanzwa , kanye Amaphoyinti we-PCR . Ngokusebenzisa izifutha ezinye nezinqambu zokuchaphaza ngokucophelela, zinikeza amafutha okuhlanzwa ngokuphathelene noma ngokuphathelene nokuchaphaza okuphakeme noma isifunda esincane ukungavuthi ukubuyiselwa kwamaphakathi.

Amaphakathi Nokuthi Yini Okuhle

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

IHLOBO LESIFAN

・ Kufuneka ukuphakama okukhulu kwe-static ukuze kubhekwe imiphumela yokugcinwa kwamaphetha okuhle kakhulu.

Amaphakathi Okufiltara

・ Amaphetha amahle (G4/F5): Ayithabatha amaphetha amakhulu (umfula, izinyawo) ukuze yisikhuthale amaphetha amanye.
・ Amaphetha amadlinga (F7/F8): Ayithabatha amaphetha amancane futhi ayehlela ubude bokusebenza kwamaphetha amahle ase-High Efficiency Particulate Air (HEPA) okungcono.
・ HEPA Filter (H13/H14): Isiqondisi sokuhlanzwa. Kusakhiwa ngokuvamile kuqala ukuze kubhekiswe ukuthi umoya ufika kwi-ISO Class 5 noma kude kakhulu.

Izinqakamba Zokulingana Kwesikhathi Nokulingana Kwesikhathi Sokushisa

・ Amaphetha okuchitha/okuchitha: Usebenzisa amanzi amachithi noma amanzi amachithi kakhulu noma ukuchitha ngqo ukuze kubuyiselwe isikhathi futhi kususwakalise umfula.
・ Ukuchitha: Usebenzisa umfula wokuchitha ongavamile, izilayili zokuchitha, noma amaphetha okuchitha. Lezi zindlela zisebenziswa emazinkhosini ngoba ziyisikhuthale futhi zinakukhathala ukuthi izibhakathini zizwe.

Ukugcina nokulingana Kwezivimba

・ Isibhakabhaka sokuchitha: Sifaka umfula wendawo yasemphakathini ukuze sithole i-oxygen futhi sibheke isikhathi sokuchitha esihle ngezindawo zokubuyela umfula okuchithiwe ukuze sibekwe isikhathi sokuchitha.
・ Amasikhuba: Ayisula umkhondo wokuchitha okuphakeme kakhulu futhi amafanisi ukuze kubuyiselwe isikhathi sokuchitha esihle kwezindawo zokuchitha.

Umkhathaliso wokubhala

・ Imiyalelo ye-DDC/PLC: Iyakhokha ngokuzenzakalelayo amasensha ukuze isheshela izikhathi zezivavanyo zezivavanyo (njengoko kuyisifunda sokuphakamisa kwe-OR ukuze kuvulekele amadoda okukhula; isifunda sokucwabela kwe-PCR labs ukuze kuvulekele amasampuli).
・ Amaphonono esifunda sokucwabela kwezinye: Ayabiza abasebenzi lapho amafiltre ayagcwaliswa futhi kufanele zilishanyelwe.

Umgangatho wokusebenza kumlinganiso wokuhlala kwesihlangu sasekhaya.

・ Ukugcina kwesifo: Isifo esitsha ne-isifo esihambelana siyagcinwa kulesi sikhundla.
・ Ukusebenzisa kabusha: Isifo sibhala ngamathegi we-G4 ne-F7 ukuze kususwane amaphakathi amaningi.
・ Ukubeka isifo emkhawini: Isifo sibhala / sibhala futhi sibhala ngokuhambisana nesikhundla esisodwa.
・ Ukuphatha kabusha kwezifo: Ufan ayabheka isifo ngamathegi we-HEPA, ukwenza yena isifo esihlakaniphi futhi esingasolwa ngamaphakathi.
・ Ukugcina kwezifo: Isifo esihlakaniphi siya kuma ngamathegi esihlakaniphi ekhaya lezifo ezikhethekileyo.
・ Ukugcina kwezifo: Isifo sibhala ngokulahleka (ngokuphakeme) noma ngokulahleka kahle ukuze kususwe nokubhala amadoda okukhula kwezifo.
・ Ukuqondisa/Ukubuyela: Isilwane sikhupha ngamaphoyinti asebomini besithili, isiqhelo esinye sibuyelwa emuva, kanti esinye sikhiphwa ukuze sikhululeke ukubalansi kwesifunda.

AHU vs. FFU vs. i-AHU esiqinisekile

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.
