Ndeipi nzira yeHEPA filter?

1. Nheyo huru: kubatwa kwezvikamu zvitatu + kufamba kwebrownian

Kukanganisa Kusina Simba

Zvidimbu zvikuru (>1 µm) hazvigone kutevera kufamba kwemhepo nekuda kwekusashanda zvakanaka uye zvinosvika zvakananga pa fiber mesh uye "zvinonamira".

Kuvharirwa

Zvidimbu zve 0.3-1 µm zvinofamba pamwe chete ne streamline uye zvinonamirwa kana zviri pedyo ne faibha.

Kupararira

Mavhairasi ne VOCs <0.1 µm zvinofamba zvisina kurongeka nekuda kwekufamba kwe Brownian uye zvinozopedzisira zvabatwa ne faibha.

Kukwezva kweElectrostatic

Mafiber emazuva ano anotakura magetsi asingachinji uye anogona kuwedzera kupinza zvidimbu zvakachajwa, zvichiwedzera kushanda zvakanaka ne5-10%.

2. Kushanda zvakanaka: H13 vs H14, usangoshevedzera kuti "HEPA"

Muna 2025, EU EN 1822-1:2009 icharamba iri iyo mwero wekuyedza unonyanya kutaurwa nezvawo:

Giredhi	Kushanda zvakanaka kwe 0.3 µm	Mienzaniso yeKushandisa
H13	99.95%	Chinochenesa mweya wemumba, firita yemotokari
H14	100.00%	Imba yekuvhiyira yechipatara, imba yakachena yesemiconductor

3. Maumbirwo: Mapleats + Kupatsanura = Kugona Kubata Guruva

HEPAHaisi "net", asi musanganiswa wegirazi kana PP une dhayamita ye0.5-2 µm, iyo inonamirwa kazana uye inoparadzaniswa nechinamira chinonyunguduka chinopisa kuti chigadzire chimiro che "deep bed" chine ukobvu hwe3-5 cm. Kana zvidimbu zvakawanda, nzvimbo yepamusoro yakakura uye hupenyu hurefu, asi kurasikirwa kwekumanikidzwa kuchawedzerawo. Mamodheru emhando yepamusoro achawedzera MERV-8 pre-filter kuti avhare zvidimbu zvikuru kutanga uye kuwedzera HEPA replacement cycle.

4. Kugadzirisa: differential pressure gauge + nguva dzose kutsiva

• Kushandiswa kumba: Tsiva mwedzi 6-12 yega yega, kana kutsiva kana musiyano wekumanikidzwa uri >150 Pa.

• Maindasitiri: Yera musiyano wekumanikidzwa kwemwedzi wega wega, woitsiva kana iri pechipiri pechipiri pesimba rekutanga.

• Zvinogona kuwachwa here? MaHEPA mashoma chete ane PTFE-coated anogona kugezwa zvishoma, uye girazi refaibha rinoparadzwa kana rasangana nemvura. Ndapota teverai mirairo.

5. Maitiro ekushandisa anozivikanwa muna 2025

• Musha wakangwara: Mapurisa ekutsvaira, maair conditioner, uye mahumidifiers ese ane H13 seyakajairika.

• Mota itsva dzinoshandisa simba: H14 cabin air conditioning filter element yava nzvimbo yekutengesa mhando dzemhando yepamusoro.

• Zvekurapa: Mobile PCR cabin inoshandisa U15 ULPA, ine mwero wekuchengetedza mavhairasi we99.9995% pasi pe0.12 µm.
