Kumvetsetsa HEPA Air Filtration

Ngakhale kusefera kwa mpweya wa HEPA kwakhala kukugwiritsidwa ntchito kuyambira Nkhondo Yachiwiri Yapadziko Lonse, chidwi ndi kufunikira kwa zosefera mpweya wa HEPA zakula kwambiri m'miyezi yaposachedwa chifukwa cha coronavirus. Kuti timvetsetse kuti kusefera kwa mpweya wa HEPA ndi chiyani, momwe kumagwirira ntchito, komanso momwe kungathandizire kupewa kufalikira kwa COVID-19, tidalankhula ndi a Thomas Nagl, mwini wa Filcom Umwelttechnologie, kampani yotsogola yosefera mpweya ku Austria.

Kodi kusefa kwa HEPA Air ndi chiyani?

HEPA ndi chidule cha kutsekeka kwamphamvu kwambiri, kapena kusefera kwa mpweya. "Zikutanthauza kuti, kuti mukwaniritse muyezo wa HEPA, fyuluta iyenera kukwaniritsa bwino lomwe," akufotokoza Nagl. "Tikalankhula zakuchita bwino, timakonda kunena za kalasi ya HEPA ya H13 kapena H14."

H13-H14 HEPA ali m'gulu lapamwamba kwambiri la kusefedwa kwa mpweya wa HEPA ndipo amaonedwa kuti ndi achipatala. "Gulu la HEPA la H13 limatha kuchotsa 99.95% ya tinthu tating'ono ting'onoting'ono ta 0.2 m'mimba mwake, pomwe kalasi ya HEPA H14 imachotsa 99.995%," akutero Nagl.

"Micron 0.2 ndiye kukula kovuta kwambiri kwa tinthu kutenga," akufotokoza Nagl. "Amadziwika kuti ndi kukula kwa tinthu tating'ono kwambiri (MPPS)." Chifukwa chake, kuchuluka komwe kwawonetsedwa ndizomwe zimasefera bwino kwambiri, ndipo tinthu tating'onoting'ono tokulirapo kapena ting'onoting'ono kuposa ma 0.2 ma micron timatsekeredwa ndi luso lapamwamba kwambiri.

Kodi Zosefera za HEPA zimapangidwa ndi chiyani ndipo zimagwira ntchito bwanji?

Zosefera zambiri za HEPA zimapangidwa ndi ulusi wagalasi wolumikizana womwe umapanga ukonde wa ulusi. "Komabe, zomwe zachitika posachedwa pakusefera kwa HEPA zikuphatikiza kugwiritsa ntchito zinthu zopangidwa ndi nembanemba," akuwonjezera Nagl.

Zosefera za HEPA zimagwira ndikuchotsa tinthu ting'onoting'ono kudzera munjira yoyambira yovutikira komanso kukhudza mwachindunji, komanso kudzera munjira zovuta kwambiri zomwe zimadziwika kuti interception and diffusion, zomwe zimapangidwa kuti zizigwira tinthu tambirimbiri.

Nagl amafulumira kufotokoza kuti ma virus samakhala okha. Amafunikira wowachereza. "Ma virus nthawi zambiri amakhala ndi tinthu tating'onoting'ono ta fumbi, kotero kuti tinthu tating'onoting'ono tamlengalenga titha kukhala ndi ma virus nawonso.

Kodi gawo la HVAC lomwe liripo lingasinthidwe kukhala HEPA?

"Ndizotheka, koma zitha kukhala zovuta kubwezeretsanso fyuluta ya HEPA mu dongosolo lomwe lilipo la HVAC chifukwa cha kupanikizika kwakukulu komwe kumasefera," akutero Nagl.
