Kodi njira yosefera ya HEPA ndi chiyani?

1. Mfundo yaikulu: kutsekera kwa magawo atatu + kusuntha kwa Brownian

Inertial Impaction

Tinthu tating'onoting'ono (> 1 µm) sitingathe kutsatira kayendedwe ka mpweya chifukwa cha inertia ndikugunda mwachindunji mauna a ulusi ndipo "zimamamatira".

Kudutsa

0.3-1 µm tinthu tating'onoting'ono timasuntha ndi streamline ndipo amamangiriridwa ngati ali pafupi ndi ulusi.

Kufalikira

Ma virus ndi ma VOCs <0.1 µm amasuntha mosakhazikika chifukwa chakuyenda kwa Brownian ndipo pamapeto pake amagwidwa ndi ulusi.

Electrostatic Attraction

Ulusi wamakono wophatikizika umanyamula magetsi osasunthika ndipo umatha kuyamwa tinthu tating'onoting'ono, ndikuwonjezera mphamvu ndi 5-10%.

2. Mulingo wogwira mtima: H13 vs H14, osangofuula "HEPA"

Mu 2025, EU EN 1822-1: 2009 idzakhalabe muyeso womwe umatchulidwa kwambiri:

Gulu	0.3 µm Kuchita bwino	Zitsanzo za Ntchito
H13	99.95%	Zoyeretsa m'nyumba, zosefera zamagalimoto
H14	100.00%	Chipinda chopangira opaleshoni, chipinda choyera cha semiconductor

3. Kapangidwe: Pleats + Partition = Kuchuluka Kwambiri Kugwira Fumbi

HEPAsi "ukonde", koma galasi CHIKWANGWANI kapena PP kusakaniza ndi m'mimba mwake 0.5-2 µm, amene pleated kangapo ndi olekanitsidwa ndi otentha kusungunula zomatira kupanga "bedi lakuya" dongosolo 3-5 masentimita wandiweyani. Kuponderezedwa kochulukirapo, kukulirakulirapo pamtunda komanso moyo wautali, koma kutayika kwamphamvu kumawonjezekanso. Zitsanzo zapamwamba zidzawonjezera zosefera za MERV-8 kuti zitseke tinthu tating'onoting'ono poyamba ndikukulitsa kuzungulira kwa HEPA.

4. Kusamalira: kusiyanitsa kuthamanga kwapakati + kusinthidwa pafupipafupi

• Kugwiritsa ntchito kunyumba: Bwezerani miyezi 6-12 iliyonse, kapena kusintha pamene kusiyana kwa kuthamanga kuli> 150 Pa.

• Mafakitale: Yezerani kusiyana kwa kuthamanga mwezi uliwonse, ndikusintha ngati ndi>>2 kukana koyambirira.

• Zochapitsidwa? Ndi ochepa PTFE TACHIMATA HEPAs akhoza kutsukidwa mopepuka, ndipo galasi CHIKWANGWANI adzawonongedwa pamene abwera kukhudzana ndi madzi. Chonde tsatirani malangizo.

5. Zochitika zodziwika bwino mu 2025

• Nyumba Yanzeru: Zosefera, zoziziritsira mpweya, ndi zoziziritsira kukhosi zonse zili ndi H13 monga muyezo.

• Magalimoto amagetsi atsopano: H14 cabin air conditioning filter element yakhala malo ogulitsa kwa zitsanzo zapamwamba.

• Zachipatala: Kanyumba ka PCR kanyumba kamagwiritsa ntchito U15 ULPA, yokhala ndi kachilombo ka 99.9995% pansi pa 0.12 µm
