Iyini indlela yokuhlunga ye-HEPA?

1. Isimiso esiyinhloko: ukuvalelwa kwezingqimba ezintathu + ukunyakaza kwe-brownian

Umthelela Ongenawo Amandla

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

Ukuvalelwa

Izinhlayiya ezingu-0.3-1 µm zihamba ne-streamline futhi zinamathele uma ziseduze ne-fiber.

Ukusabalala

Ama-virus nama-VOC <0.1 µm azulazula ngokungajwayelekile ngenxa yokunyakaza kwama-brownian futhi ekugcineni abanjwa yi-fiber.

Ukukhanga Okunamandla Kagesi

Imicu yesimanje ehlanganisiwe ithwala ugesi ongashintshi futhi ingamunca izinhlayiya ezishajiwe, ikhulise ukusebenza kahle ngo-5-10%.

2. Izinga lokusebenza kahle: H13 vs H14, ungamane umemeze uthi “HEPA”

Ngo-2025, i-EU EN 1822-1:2009 izoqhubeka nokuba indinganiso yokuhlola evame ukucashunwa kakhulu:

Ibanga	Ukusebenza kahle okungu-0.3 µm	Izibonelo Zokusebenza
H13	99.95%	Isihlanzi somoya sasekhaya, isihlungi semoto
H14	100.00%	Igumbi lokuhlinza esibhedlela, igumbi lokuhlanza le-semiconductor

3. Isakhiwo: Ama-Pleats + Ukwahlukanisa = Amandla Okugcina Uthuli Olukhulu

I-HEPAakuyona "inethi", kodwa ingxube yefayibha yengilazi noma i-PP enobubanzi obungu-0.5-2 µm, ehlanganiswa izikhathi ezingamakhulu futhi ihlukaniswe yisinamathiseli esishisayo esincibilikayo ukuze sakhe isakhiwo "sombhede ojulile" esingu-3-5 cm ubukhulu. Uma ama-pleats amaningi, indawo engaphezulu inkulu futhi isikhathi eside siphila, kodwa ukulahlekelwa kwengcindezi nakho kuzokwanda. Amamodeli aphezulu azokwengeza isihlungi sangaphambi kwe-MERV-8 ukuvimba izinhlayiya ezinkulu kuqala futhi andise umjikelezo wokufaka esikhundleni se-HEPA.

4. Ukulungiswa: i-differential pressure gauge + ukushintshwa okuvamile

• Ukusetshenziswa ekhaya: Shintsha njalo ezinyangeni ezingu-6-12, noma shintsha uma umehluko wokucindezela ungaphezulu kuka-150 Pa.

• Ezezimboni: Kala umehluko wokucindezela njalo ngenyanga, bese uwushintsha uma ungaphezu kokuphindwe kabili kokumelana kokuqala.

• Kuyagezwa? Ama-HEPA ambalwa kuphela ambozwe nge-PTFE angagezwa kancane, futhi i-fiber yengilazi izobhujiswa uma ihlangana namanzi. Sicela ulandele imiyalelo.

5. Izimo zohlelo lokusebenza ezidumile ngo-2025

• Ikhaya elihlakaniphile: Ama-Sweeper, ama-air conditioner, kanye nama-humidifier konke kufakwe i-H13 njengejwayelekile.

• Izimoto ezintsha zamandla: Isici sesihlungi somoya opholile sekhabhini le-H14 sesibe yindawo yokuthengisa yamamodeli asezingeni eliphezulu.

• Ezokwelapha: Ikhabhini le-PCR elihambayo lisebenzisa i-U15 ULPA, ngesilinganiso sokugcina igciwane esingu-99.9995% ngaphansi kuka-0.12 µm.
