Nruab nrab-Kev Ua Tau Zoo Paj Rwb Hnab Rau F5-F9 Cua Txias Systems: Nta, Daim Ntawv Thov & Cov txiaj ntsig
CovNruab nrab -Efficiency Cotton Pocket Lim(tseem hu ua athawj lub hnab lim) yog ib qho tseem ceeb hauv HVAC systems, tsim los ntes cov nruab nrab - qhov loj me (1-10 µm) hauv cov tshuab cua txias. Nws yog feem ntau cais raws liEN779: 2012 / ISO 16890 tus qauvRaws li F5, F6, F7, F8, lossis F9, nyob ntawm nws qhov kev pom zoo. Hauv qab no yog cov ncauj lus kom ntxaws txog nws cov yam ntxwv, kev siv, thiab qhov zoo.
1. Cov yam ntxwv tseem ceeb
Lim Efficiency (EN779 / ISO 16890):
F5: 40-60% ASHRAE plua plav qhov chaw ua haujlwm (nruj pom, PM10).
F660-80% (nruab nrab pom, PM5).
F780-90% (zoo pom, PM2.5).
F8: 90–95% (ePM1 50-65%, pom zoo heev).
F9: 95%+ (ePM1 65-80%, siab-efficiency filtration).
Kev tsim kho:
Paj rwb/Synthetic Media: Ua los ntawm cov uas tsis yog -woven polyester los yog paj rwb sib tov rau durability thiab tsis tshua muaj siab poob.
Pocket Design: Ntau- cov hnab ris txheej nce qhov chaw pom qhov chaw (piv txwv li, 6–12 hnab ris ib lim).
Galvanized steel ncej: Xeb-resistant thiab nruj rau ntev- siv sijhawm.
Airflow & Siab poob:
Tsawg pib tsis kam (20-50 Pa) txo kev siv zog.
Cov plua plav siab- tuav lub peev xwm (txog 500 g / m²) txuas lub neej kev pab cuam.
Cov ntawv pov thawj:
Ua raws liEurovent, ASHRAE 52.2, thiab LEEDCov qauv rau huab cua hauv tsev (IAQ).
2. Kev siv hauv HVAC Systems
Cov tsev lag luam:
Chaw ua hauj lwm yees, khw khw, thiab tsev so siv F5-F7 lim rau cua dav dav.
Cov Khoom Siv Muaj:
Pharmaceuticals, electronics, thiab food processing plants siv F8–F9 filters for cleanroom pre-filtration.
Kev kho mob:
Cov tsev kho mob thiab cov chaw soj nstuam siv F7-F9 lim los tiv thaiv kev ua xua thiab cov kab mob.
Data Centers:
Tiv thaiv plua plav buildup nyob rau hauv cov neeg rau zaub mov chav, txo cov cua txias system strain.
3. Cov txiaj ntsig ntawm kev siv paj rwb hnab lim lim
Tus nqi -Kev lim dej zoo:
Sib npaug kev ua tau zoo thiab pheej yig piv rau HEPA lim.
Zog Efficiency:
Kev poob qis qis txo cov kiv cua siv zog txog li 20%.
Lub neej ua haujlwm ntev:
Pocket tsim tuav cov plua plav ntau dua (txog 6 lub hlis hauv cov xwm txheej nruab nrab).
Kev tu yooj yim:
Lub teeb yuag thiab hloov tau yam tsis muaj qhov system kaw.
4. Daim ntawv qhia kev xaiv
| Lim Qib | Kev tshem tawm Particle loj (µm) | Kev siv yam | Pom zoo Hloov (hli) |
|---|---|---|---|
| F5 | >5 µm | Kev tso cua dav dav | 3–4 |
| F6 | 3–5 µm | Chaw ua haujlwm, tsev kawm ntawv | 4–6 |
| F7 | 1–3 µm | Tsev kho mob, chav huv | 6–8 |
| F8 | 0.5–1 µm | Pharmaceuticals, electronics | 8–10 |
| F9 | <0.5 µm | Kev tsim khoom tseem ceeb | 10–12 |
Yam uas yuav tau xav txog:
Airflow tus nqi: Sib phim cheeb tsam lim (piv txwv li, 500–2000 m³ / h ib lim) rau lub peev xwm.
Cov av noo: Synthetic media resists noo noo zoo dua paj rwb nyob rau hauv siab - av noo ib puag ncig.
Lim kawg: F5–F7 cov lim dej feem ntau yog siv ua ntej- lim rau HEPA/ULPA systems.
5. Cov lus qhia txog kev tu
Kev tshuaj xyuas tsis tu ncua: Check pressure drop monthly; replace if >250 pab.
Kev pov tseg kom raug: Pov tseg cov lim siv hauv cov hnab ntim khoom kom tiv thaiv kom tsis txhob muaj kab mob.
Cia: Khaws cov lim lim hauv qhov chaw qhuav, huv si kom tsis txhob muaj kev puas tsuaj ntawm cov xov xwm.
