Ithini indlela yokuhlunga ye-HEPA?

1. Isimiso esiyinhloko: ukungenelela kwezendlalelo ezintathu + ukunyakaza kwe-Brownian

Umthelela Ongabambeki

Izinhlayiya ezinkulu (>1 µm) azikwazi ukulandela ukugeleza komoya ngenxa ye-inertia futhi zishaye ngokuqondile i-fiber mesh futhi "ziyanamathela".

Ukungena

Izinhlayiya ezingu-0.3-1 µm zihamba ne-streamline futhi zinamathiselwe uma ziseduze nefayibha.

Ukusabalalisa

Amagciwane nama-VOC angu-<0.1 µm akhukhuleka ngokungavamile ngenxa yokunyakaza kwe-Brownian futhi agcine ethwetshulwe yifayibha.

Electrostatic Attraction

Imicu yesimanje eyinhlanganisela ithwala ugesi omile futhi ingamunca izinhlayiya ezishajwayo, ikhulise ukusebenza kahle ngomunye u-5-10%.

2. Izinga lokusebenza kahle: H13 vs H14, ungavele umemeze "HEPA"

Ngo-2025, i-EU EN 1822-1:2009 isazoba yizinga lokuhlola elivame ukucashunwa:

Ibanga	0.3 µm Ukusebenza kahle	Izibonelo Zohlelo Lokusebenza
H13	99.95%	Isihlanzi somoya sasekhaya, isihlungi semoto
H14	100.00%	Igumbi lokuhlinzela esibhedlela, igumbi elihlanzekile le-semiconductor

3. Isakhiwo: Ama-Pleats + Ingxenye = Amandla Okubamba Uthuli Olukhulu

I-HEPAakuyona "inetha", kodwa i-fiber yengilazi noma inhlanganisela ye-PP enobubanzi obungu-0.5-2 µm, ekhonjiswa izikhathi ezingamakhulu futhi ihlukaniswe nge-adhesive encibilikayo eshisayo ukuze yakhe isakhiwo "sombhede ojulile" ongu-3-5 cm ubukhulu. I-pleats eyengeziwe, indawo ephezulu kanye nempilo ende, kodwa ukulahlekelwa kwengcindezi kuzokwanda. Amamodeli asezingeni eliphezulu azokwengeza isihlungi sangaphambili se-MERV-8 ukuze avimbe izinhlayiya ezinkulu kuqala futhi andise umjikelezo wokubuyisela we-HEPA.

4. Ukugcinwa: igeji yengcindezi ehlukile + ukushintshwa okuvamile

• Ukusetshenziswa kwasekhaya: Faka esikhundleni njalo ezinyangeni eziyisi-6-12, noma shintsha lapho umehluko wengcindezi ungu>150 Pa.

• Imboni: Kala umehluko wengcindezi njalo ngenyanga, bese uwushintsha uma kungu >2 izikhathi zokuphikiswa kokuqala.

• Iyawasheka? Ama-HEPA ambalwa ane-PTFE ambozwe nge-PTFE angawashwa kalula, futhi i-fiber yengilazi izobhujiswa uma ihlangana namanzi. Sicela ulandele imiyalelo.

5. Izimo zohlelo lokusebenza ezidumile ngo-2025

• I-Smart Home: Amashanela, ama-air conditioner, nama-humidifiers konke kufakwe i-H13 njengokujwayelekile.

• Izimoto zamandla amasha: Isici sesihlungi se-H14 cabin air conditioning isiphenduke indawo yokuthengisa kumamodeli asezingeni eliphezulu.

• Ezokwelapha: Ikhabethe le-PCR engumakhalekhukhwini lisebenzisa i-U15 ULPA, enezinga lokugcinwa kwegciwane elingu-99.9995% ngaphansi kuka-0.12 µm
