Kunzwisisa HEPA Air Filtration

Kunyangwe HEPA kusefa kwemhepo kwave kushandiswa kubva Hondo Yenyika II, kufarira uye kudiwa kweHEPA mafirita emhepo kwakakura zvakanyanya mumwedzi ichangopfuura nekuda kweiyo coronavirus. Kuti tinzwisise kuti HEPA kusefa kwemhepo chii, kuti inoshanda sei, uye kuti ingabatsire sei kudzivirira kupararira kweCCIDID-19, takataura naThomas Nagl, muridzi weFilcom Umwelttechnologie, kambani inotungamira yekusefa kwemhepo muAustria.

Chii chinonzi HEPA Air Filtration?

HEPA idimikira rekuti yakakwira-inoshanda particulate kusungwa, kana kusefa kwemhepo. "Zvinoreva kuti, kuti isangane neHEPA chiyero, sefa inofanirwa kuita yakatsanangurwa inoshanda," anotsanangura Nagl. "Kana tichitaura nezvekuita zvakanaka, isu tiri kutaura nezve HEPA giredhi reH13 kana H14."

H13-H14 HEPA iri mukati mechikamu chepamusoro cheHEPA kusefa kwemhepo uye inoonekwa seyekurapa-giredhi. "Hepa yeHEPA yeH13 inogona kubvisa 99.95% yezvikamu zvose mumhepo inoyera 0.2 microns muhupamhi, nepo HEPA giredhi H14 inobvisa 99.995%," anodaro Nagl.

"Iyo 0.2 micron ndiyo yakanyanya kuoma saizi yechinhu kutora," anotsanangura Nagl. "Inozivikanwa seyakanyanya kupinda particle size (MPPS)." Naizvozvo, iyo yakaratidzwa muzana ndiyo yakaipisisa yekusefa, uye zvimedu zvakakura kana zvidiki pane 0.2 mamicrons akabatwa nekutonyanya kushanda zvakanaka.

Iyo HEPA yakajairwa inoteya zvidiki zvidiki, kusanganisira izvo zvisingaonekwe nemeso emunhu, asi zvinokuvadza kuhutano hwedu, senge mavhairasi uye mabhakitiriya. Sezvo dandemutande remafibers ari mugiredhi rekurapa HEPA sefa yakanyanya kusimba, anogona kuteya tudikidiki pachiyero chepamusoro, uye anonyatso shanda pakubvisa chepfu inokuvadza kubva munharaunda.

Pakuona, bvudzi remunhu riri pakati pe80 ne100 microns mudhayamita. Pollen i100-300 microns. Utachiona hunosiyana pakati pe> 0.1 ne0.5 microns. Zvisinei, zvakakosha kuyeuka kuti, kunyange zvazvo H13 HEPA inonzi 99.95% inoshanda pakubvisa zvimedu mumhepo inoyera 0.2 microns, iyi ndiyo yakaipisisa.
