Ndeipi HEPA sefa nzira?

1. Core musimboti: matatu-layer interception + Brownian kufamba

Inertial Impaction

Zvimedu zvakakura (> 1 µm) hazvigone kutevedzera mafambiro emhepo nekuda kweinertia uye zvakananga kurova fiber mesh uye "yakanamira".

Kupindira

0.3-1 µm zvidimbu zvinofamba neinoyerera uye zvinonamirwa kana zviri padyo nefiber.

Diffusion

Mavhairasi uye maVOC <0.1 µm anokukurwa zvisingaite nekuda kweBrownian kufamba uye anozopedzisira atorwa nefiber.

Electrostatic Attraction

Mafiibhi emazuva ano anoumbwa anotakura magetsi akamira uye anogona kuwedzera kubhadharisa zvimedu, zvichiwedzera kushanda zvakanaka neimwe 5-10%.

2. Chiyero chekubudirira: H13 vs H14, usangoshevedzera "HEPA"

Muna 2025, EU EN 1822-1: 2009 ichave ichinyanya kutaurwa chiyero chebvunzo:

Giredhi	0.3 µm Kubudirira	Mienzaniso Yekushandisa
H13	99.95%	Mumba air purifier, mota sefa
H14	100.00%	Imba yekuvhiya yechipatara, semiconductor yakachena imba

3. Chimiro: Pleats + Partition = Maximum Dust Holding Capacity

HEPAhaisi "mambure", asi fiber yegirazi kana PP inosanganiswa nehupamhi hwe 0.5-2 µm, iyo inopembererwa kane mazana uye inoparadzaniswa neinopisa yakanyunguduka adhesive kuti iite "mubhedha wakadzika" chimiro 3-5 cm gobvu. Iyo yakawanda pleats, iyo yakakura nzvimbo yepamusoro uye yakareba hupenyu, asi kurasikirwa kwekumanikidza kuchawedzerawo. Mhando dzepamusoro-soro dzichawedzera MERV-8 pre-filter kuti ivhare zvimedu zvakakura kutanga uye kuwedzera HEPA kutsiva kutenderera.

4. Maintenance: kusiyanisa kudzvinyirira geji + nguva dzose kutsiva

• Kushandisa pamba: Dzorera mwedzi 6-12 yega yega, kana kutsiva kana mutsauko wekumanikidza uri> 150 Pa.

• Indasitiri: Edza mutsauko wekumanikidzwa mwedzi wega wega, uye woitsiva kana iri > 2 nguva yekutanga kuramba.

• Inogona kushambidzika? Mashomanana ePTFE-akavharwa HEPA anogona kushambidzwa zvishoma, uye girazi fiber ichaparadzwa kana yasangana nemvura. Ndapota tevera mirairo.

5. Mamiriro ekushandisa akakurumbira muna 2025

• Imba yakangwara: Magetsi, ma air conditioner, uye humidifiers zvese zvine H13 seyakajairwa.

• Motokari itsva dzemagetsi: H14 cabin air conditioning filter element yava nzvimbo yekutengesa yemhando dzepamusoro.

• Chiremba: Mobile PCR kabhini inoshandisa U15 ULPA, ine hutachiwana hwekuchengetedza hutachiwana hwe99.9995% pasi pe0.12 µm
