Kedu usoro nzacha HEPA?

1. Ụkpụrụ isi: nkwụsị nke okpukpu atọ + mmegharị Brownian

Mmetụta Inertial

Akụkụ buru ibu (> 1 µm) enweghị ike iso ikuku ikuku n'ihi inertia wee daa eriri eriri ozugbo wee “rapara”.

Ntinye aka

0.3-1 µm irighiri ihe na-aga na streamline ma tinye ya ma ọ bụrụ na ha dị nso na eriri.

Mgbasa

Nje Virus na VOC <0.1 µm na-efegharị oge niile n'ihi ngagharị Brownian na-emecha weghara ya site na eriri.

Electrostatic Mmanya

Ngwakọta ihe mejupụtara nke ọgbara ọhụrụ na-ebu ọkụ eletrik kwụ ọtọ ma nwee ike na-amịkọrọ mkpụrụ irighiri ebubo, na-abawanye arụmọrụ site na 5-10% ọzọ.

2. Ọkwa arụmọrụ: H13 vs H14, agụla naanị "HEPA"

Na 2025, EU EN 1822-1: 2009 ka ga-abụ ọkọlọtọ ule a na-akpọkarị:

Ọkwa	0.3 µm arụmọrụ	Ihe atụ ngwa
H13	99.95%	Nchacha ikuku ụlọ, nzacha ụgbọ ala
H14	100.00%	Ime ụlọ ịwa ụlọ ọgwụ, ụlọ semiconductor dị ọcha

3. Nhazi: Pleats + Nkebi = Ike ijide uzuzu kacha

HEPAabụghị "ụgbụ", kama eriri iko ma ọ bụ ngwakọta PP nke nwere dayameta nke 0.5-2 µm, nke a na-atọ ụtọ ọtụtụ narị ugboro ma kewapụ ya site na nrapado na-ekpo ọkụ na-agbaze iji mepụta usoro "akwa miri emi" 3-5 cm gbara ọkpụrụkpụ. Ka pleats ka ukwuu, ebe elu na-ebuwanye ibu na ogologo ndụ, mana ọnwụ nrụgide ga-abawanye. Ụdị dị elu ga-agbakwunye ihe nzacha MERV-8 iji gbochie nnukwu irighiri ihe mbụ wee gbatịa okirikiri nnọchi HEPA.

4. Nlekọta: ihe nlele nrụgide dị iche + mgbanwe mgbe niile

• Iji ụlọ: Dochie ọnwa 6-12 ọ bụla, ma ọ bụ dochie mgbe ọdịiche nrụgide dị> 150 Pa.

• Ụlọ ọrụ mmepụta ihe: tụọ ọdịiche nrụgide kwa ọnwa, ma dochie ya ma ọ bụrụ> 2 ugboro nkwụsị mbụ.

• Enwere ike ịsacha? Naanị HEPA nwere mkpuchi PTFE ole na ole ka enwere ike ịsacha obere ọkụ, a ga-ebibikwa eriri iko ahụ mgbe ọ batara na mmiri. Biko soro ntuziaka.

5. Ọnọdụ ngwa ama ama na 2025

• Smart Home: Ndị na-asachapụ ihe, ikuku ntụ oyi, na ihe na-ekpo ọkụ ka ejiri H13 dị ka ọkọlọtọ.

• Ụgbọ ala ume ọhụrụ: H14 cabin air conditioning filter element abụrụla ebe a na-ere ahịa maka ụdị dị elu.

• Ahụike: Ụlọ PCR Mobile na-eji U15 ULPA, yana ọnụọgụ njigide nje nke 99.9995% n'okpuru 0.12 µm
