Nubuhe buryo bwo kuyungurura HEPA?

1. Ihame shingiro: guhuza ibice bitatu + Icyerekezo cya Brown

Ingaruka zidasanzwe

Ibice binini (> 1 µm) ntibishobora gukurikira umwuka mubi kubera inertia hanyuma bigahita bikubita fibre mesh kandi "bikomanze".

Kwifata

0.3-1 µm ibice bigenda hamwe numurongo kandi bifatanye niba byegereye fibre.

Gutandukana

Virusi na VOC <0.1 µm bigenda bidasanzwe kubera kugenda kwa Brown kandi amaherezo bigafatwa na fibre.

Gukurura amashanyarazi

Fibre igezweho itwara amashanyarazi ahamye kandi irashobora kwongeramo ibice byashizwemo, byongera imikorere kubindi 5-10%.

2. Urwego rukora neza: H13 vs H14, ntutakaze "HEPA"

Muri 2025, EU EN 1822-1: 2009 bizakomeza kuba ibipimo byavuzwe cyane:

Icyiciro	0.3 µm Ingaruka	Ingero zo gusaba
H13	99,95%	Isuku yo mu rugo yo mu rugo, kuyungurura imodoka
H14	100.00%	Icyumba cyo gukoreramo ibitaro, icyumba gisukuye

3. Imiterere: Ibyishimo + Igice = Ubushobozi ntarengwa bwo gufata umukungugu

HEPAntabwo ari "net", ahubwo fibre yikirahure cyangwa PP ivanze na diameter ya 0.5-2 µm, ishimishwa inshuro magana kandi igatandukanywa nigishishwa gishushe kugirango ikore "uburiri bwimbitse" uburebure bwa cm 3-5. Kureshya cyane, nubuso bunini nuburebure bwubuzima, ariko gutakaza umuvuduko nabyo biziyongera. Moderi yohejuru izongeramo MERV-8 mbere yo kuyungurura kugirango ibuze ibice binini mbere no kwagura urwego rwo gusimbuza HEPA.

4. Kubungabunga: igipimo cyumuvuduko ukabije + gusimburwa bisanzwe

• Gukoresha murugo: Simbuza buri mezi 6-12, cyangwa usimbuze mugihe itandukaniro ryumuvuduko ari> 150 Pa.

• Inganda: Gupima itandukaniro ryumuvuduko buri kwezi, hanyuma uyisimbuze niba ari> inshuro 2 kurwanya kwambere.

Gukaraba? Gusa HEPAs yometse kuri PTFE irashobora gukaraba byoroheje, kandi fibre yikirahure izarimbuka iyo ihuye namazi. Nyamuneka kurikiza amabwiriza.

5. Ibintu bizwi cyane muri 2025

• Urugo rwubwenge: Gusukura, konderasi, hamwe nubushuhe byose bifite ibikoresho bya H13 nkibisanzwe.

• Imodoka nshya zingufu: H14 cabine yubushyuhe bwo kuyungurura ibintu byahindutse kugurisha moderi zohejuru.

• Ubuvuzi: Akazu ka PCR kagendanwa gakoresha U15 ULPA, hamwe na virusi ya 99,9995% munsi ya 0.12 µm
