Ithini indlela yokucoca i-HEPA?

1. Umgaqo ongundoqo: ukuvalelwa kwee-layers ezintathu + intshukumo yeBrownian

Impembelelo Engasebenziyo

Amasuntswana amakhulu (>1 µm) awakwazi ukulandela ukuhamba komoya ngenxa ye-inertia aze abethe ngqo kwi-fiber mesh aze "anamathele".

Ukuvalelwa

Amasuntswana angama-0.3-1 µm ahamba kunye ne-streamline kwaye anamathele ukuba akufutshane nefayibha.

Ukusasazeka

Iintsholongwane kunye neeVOCs <0.1 µm zihamba ngokungaqhelekanga ngenxa yentshukumo yeBrownian kwaye ekugqibeleni zibanjwa yifayibha.

Umtsalane we-Electrostatic

Iifayibha ezidityanisiweyo zanamhlanje zithwala umbane ongashukumiyo kwaye zingakwazi ukufunxa amasuntswana atshajiweyo, zinyusa ukusebenza kakuhle nge-5-10%.

2. Inqanaba lokusebenza kakuhle: H13 vs H14, musa ukukhwaza nje uthi "HEPA"

Ngowama-2025, i-EU EN 1822-1:2009 iza kuba yeyona migangatho yovavanyo ekhankanywa rhoqo:

Ibanga	Ukusebenza kakuhle kwe-0.3 µm	Imizekelo yoSetyenziso
H13	99.95%	Isicoci somoya sasekhaya, isihluzi semoto
H14	100.00%	Igumbi lotyando lesibhedlele, igumbi lokucoca le-semiconductor

3. Ulwakhiwo: Iipleyiti + Ukwahlulahlula = Ubuninzi boMgangatho wokubamba uthuli

I-HEPAayisiyo "inethi", kodwa yi-fiber yeglasi okanye i-PP mix enobubanzi obuyi-0.5-2 µm, egobile amaxesha amaninzi kwaye yahlulwe yi-hot melt adhesive ukwenza isakhiwo "sebhedi enzulu" esinobukhulu obuyi-3-5 cm. Okukhona ii-pleats zininzi, kokukhona indawo yomphezulu inkulu kwaye ubomi buhlala ixesha elide, kodwa ukulahleka koxinzelelo nako kuya kwanda. Iimodeli eziphezulu ziya kongeza isihluzo sangaphambi kwe-MERV-8 ukuvimba amasuntswana amakhulu kuqala kwaye zandise umjikelo wokutshintshwa kwe-HEPA.

4. Ulondolozo: igeyiji yoxinzelelo eyahlukileyo + ukutshintshwa rhoqo

• Ukusetyenziswa ekhaya: Tshintsha rhoqo emva kweenyanga ezi-6-12, okanye utshintshe xa umahluko woxinzelelo ungaphezulu kwe-150 Pa.

• Imizi-mveliso: Linganisa umahluko woxinzelelo inyanga nenyanga, uze uwutshintshe ukuba ungaphezulu kwezihlandlo ezibini kunokumelana kokuqala.

• Ingahlanjwa? Zimbalwa iiHEPA ezigqunywe yiPTFE ezinokuhlanjwa kancinci, kwaye ifayibha yeglasi iya kutshatyalaliswa xa idibana namanzi. Nceda ulandele imiyalelo.

5. Iimeko ezidumileyo zezicelo ngo-2025

• Ikhaya elikrelekrele: Ii-Sweepers, ii-air conditioner, kunye nee-humidifiers zonke zixhotyiswe nge-H13 njengesiqhelo.

• Iimoto ezintsha zamandla: Isihluzi somoya opholileyo sekhabhini ye-H14 siye saba yindawo yokuthengisa kwiimodeli ezikumgangatho ophezulu.

• Ezonyango: Ikhabhini ye-PCR ephathwayo isebenzisa i-U15 ULPA, enezinga lokugcina iintsholongwane eliyi-99.9995% ngaphantsi kwe-0.12 µm.
