Uburyo bwo kuyungurura HEPA ni ubuhe?

1. Ihame ry'ingenzi: gufata ibice bitatu + kugenda kwa Brownian

Ingaruka zitagira imbaraga

Uduce duto (> 1 µm) ntidushobora gukurikira ikirere bitewe n’uburemere bw’umwuka ngo dukore ku muyoboro wa fibre hanyuma "tukaba twafashe".

Gufata

Uduce twa 0.3-1 µm tugenda hamwe n'uruhererekane rw'amazi kandi dufatanye iyo turi hafi y'umugozi.

Gukwirakwiza

Virusi na VOC <0.1 µm zigenda buhoro buhoro bitewe n'ingendo za Brownian kandi amaherezo zifatwa na fibre.

Gukurura amashanyarazi

Insinga zigezweho zigizwe n'ibinyabutabire zitwara amashanyarazi adahindagurika kandi zishobora no kwinjiza uduce dushyushye, zikongera ubushobozi ku kigero cya 5-10%.

2. Urwego rw'imikorere myiza: H13 vs H14, ntugasakuze gusa ngo "HEPA"

Mu 2025, EU EN 1822-1:2009 izaba ikiri igipimo gikunze kuvugwa cyane mu isuzuma:

Icyiciro	Ubushobozi bwa 0.3 µm	Ingero z'Ishyirwa mu Bikorwa
H13	99.95%	Akamashini ko gusukura umwuka mu rugo, akayunguruzo k'imodoka
H14	100.00%	Icyumba cyo kubaga mu bitaro, icyumba gisukuye cya semiconductor

3. Imiterere: Impande + Igice = Ubushobozi ntarengwa bwo gufata ivumbi

HEPASi "urushundura", ahubwo ni uruvange rw'ibirahure cyangwa PP rufite umurambararo wa 0.5-2 µm, rushyirwamo imigozi inshuro amagana kandi rugatandukanywa n'ubushyuhe bushyushye bwo gushonga kugira ngo rukore imiterere "y'uburiri bwimbitse" ifite ubugari bwa cm 3-5. Uko imigozi myinshi igenda iba minini, ni ko ubuso burushaho kuba bunini kandi ni ko ubuzima bumara igihe kirekire, ariko igihombo cy'umuvuduko nacyo kiziyongera. Imiterere yo mu rwego rwo hejuru izongeraho MERV-8 pre-filter kugira ngo ihagarike uduce duto mbere na mbere kandi yongere igihe cyo gusimbuza HEPA.

4. Kubungabunga: igipimo cy'umuvuduko w'impinduka + gusimbuza buri gihe

• Gukoresha mu rugo: Simbuza buri mezi 6-12, cyangwa usimbuze iyo itandukaniro ry'umuvuduko riri >150 Pa.

• Inganda: Pima itandukaniro ry'umuvuduko buri kwezi, hanyuma uwusimbuze niba ukubye inshuro ebyiri z'ubudahangarwa bwa mbere.

• Bishobora kumeswa? Hepa nke gusa za PTFE zishobora kozwa buhoro, kandi fibre y'ikirahure izangirika iyo ikoze mu mazi. Nyamuneka kurikiza amabwiriza.

5. Uburyo bwo gukoresha porogaramu buzwi cyane muri 2025

• Inzu nziza: Imashini zisukura, imashini zikonjesha, n'imashini zitanga ubushuhe byose bifite H13 nk'uko bisanzwe.

• Imodoka nshya zikoresha ingufu: Agace ka H14 karimo umwuka ushyushya kabaye ahantu hagurishirizwa cyane ku modoka zigezweho.

• Ubuvuzi: Akazu kagendanwa ka PCR gakoresha U15 ULPA, gafite igipimo cyo kubika virusi kiri munsi ya 0.12 µm ku kigero cya 99.9995%.
