Kodi njira yogwiritsira ntchito fyuluta ya HEPA ndi iti?

1. Mfundo yaikulu: kutsekereza kwa magawo atatu + kuyenda kwa Brownian

Kukhudzidwa Kwambiri

Tinthu tating'onoting'ono tating'onoting'ono (>1 µm) sitingathe kutsatira kayendedwe ka mpweya chifukwa cha kulephera kwa mpweya ndipo timagunda mwachindunji pa ulusi wa fiber ndipo "timamatira".

Kuletsa

Tinthu tating'onoting'ono ta 0.3-1 µm timayenda ndi streamline ndipo timalumikizidwa ngati tili pafupi ndi ulusi.

Kufalikira

Mavairasi ndi ma VOC <0.1 µm amayendayenda mosakhazikika chifukwa cha kuyenda kwa Brownian ndipo pamapeto pake amagwidwa ndi ulusi.

Kukopa kwa Magetsi

Ulusi wamakono wopangidwa ndi zinthu zosiyanasiyana umanyamula magetsi osasunthika ndipo umatha kuyamwa tinthu tating'onoting'ono tomwe timayatsidwa, zomwe zimapangitsa kuti ntchito ikhale yogwira ntchito bwino ndi 5-10%.

2. Kugwira ntchito bwino: H13 vs H14, musamangofuula kuti "HEPA"

Mu 2025, EU EN 1822-1:2009 idzakhalabe muyezo woyesedwa wotchulidwa kwambiri:

Giredi	Kugwiritsa Ntchito Bwino kwa 0.3 µm	Zitsanzo za Ntchito
H13	99.95%	Chotsukira mpweya wa m'nyumba, fyuluta ya galimoto
H14	100.00%	Chipinda chochitira opaleshoni cha chipatala, chipinda choyera cha semiconductor

3. Kapangidwe: Zingwe + Kugawa = Kutha Kwambiri Kugwira Fumbi

HEPASi "ukonde", koma ndi ulusi wagalasi kapena PP wosakaniza wokhala ndi mainchesi a 0.5-2 µm, womwe umapindidwa kambirimbiri ndikulekanitsidwa ndi guluu wosungunuka wotentha kuti upange kapangidwe ka "bedi lakuya" kokhala ndi makulidwe a 3-5 cm. Ma pleats ambiri, malo ozungulira amakhala akulu komanso amakhala ndi moyo wautali, koma kutayika kwa kuthamanga kudzawonjezekanso. Ma model apamwamba adzawonjezera fyuluta yoyambirira ya MERV-8 kuti atseke tinthu tating'onoting'ono tambiri poyamba ndikukulitsa nthawi yosinthira ya HEPA.

4. Kukonza: choyezera kuthamanga kosiyana + kusintha nthawi zonse

• Kugwiritsa ntchito kunyumba: Sinthanitsani miyezi 6-12 iliyonse, kapena sinthani ngati kusiyana kwa kuthamanga kuli >150 Pa.

• Zamakampani: Yesani kusiyana kwa kuthamanga kwa mpweya mwezi uliwonse, ndipo musinthe ngati kuli kokwanira kuwirikiza kawiri kuposa kukana koyamba.

• Kodi n'zotheka kutsuka? Ma HEPA ochepa okha okhala ndi PTFE omwe ndi omwe angatsukidwe pang'ono, ndipo ulusi wagalasi udzawonongeka ukakhudza madzi. Chonde tsatirani malangizo.

5. Zochitika zodziwika bwino zogwiritsidwa ntchito mu 2025

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

• Magalimoto atsopano amphamvu: Chosefera cha mpweya woziziritsa mpweya cha H14 chakhala malo ogulitsa mitundu yapamwamba kwambiri.

• Zachipatala: Kabati ya Mobile PCR imagwiritsa ntchito U15 ULPA, yokhala ndi chiŵerengero chosungira ma virus cha 99.9995% pansi pa 0.12 µm.
