Yintoni indlela yokucoca iHEPA?

1. Umgaqo ongundoqo: ukungenelela kwemigangatho emithathu + intshukumo yeBrownian

Impembelelo eNgaphakathi

Amasuntswana amakhulu (>1 µm) akakwazi ukulandela ukuhamba komoya ngenxa ye-inertia kwaye abethe ngqo kumnatha wefiber kwaye "axinge".

Ukuthintela

I-0.3-1 µm amasuntswana ahamba kunye ne-streamline kwaye aqhotyoshelwe ukuba asondele kwifiber.

Ukusasazwa

Iintsholongwane kunye nee-VOCs <0.1 µm zihamba ngokungafanelekanga ngenxa yentshukumo yeBrownian kwaye ekugqibeleni zibanjwa lusinga.

Umtsalane we-Electrostatic

Iintsinga zanamhlanje ezidibeneyo zithwala umbane ongatshintshiyo kwaye ziyakwazi ukufunxa amasuntswana ahlawulisiweyo, zinyusa ukusebenza kakuhle ngenye i-5-10%.

2. Inqanaba lobuchule: H13 vs H14, musa ukukhwaza nje "HEPA"

Ngo-2025, i-EU EN 1822-1: 2009 iseza kuba ngowona mgangatho wovavanyo ukhankanywa ngokuqhelekileyo:

IBanga	0.3 µm Ukusebenza kakuhle	Imizekelo yosetyenziso
H13	99.95%	Isicoci somoya sasekhaya, isihluzi semoto
H14	100.00%	Igumbi lokutyanda esibhedlele, igumbi elicocekileyo le-semiconductor

3. Ulwakhiwo: IiPleats + Ukwahlula = Ubuninzi boKubamba uThuli Umthamo

HEPAayisiyiyo "inetha", kodwa i-fiber yeglasi okanye i-PP blend kunye ne-diameter ye-0.5-2 µm, ekhonjiswe ngamakhulu amaxesha kwaye yahlulwe yi-adhesive eshushu enyibilikayo ukwenza "ibhedi enzulu" isakhiwo 3-5 cm ubukhulu. I-pleats eninzi, inkulu indawo ephezulu kunye nobomi obude, kodwa ukulahlekelwa koxinzelelo kuya kwanda. Iimodeli eziphakamileyo ziza kongeza i-MERV-8 yangaphambili yokucoca ukuvala amaqhekeza amakhulu kuqala kwaye yandise umjikelezo wokutshintshwa kwe-HEPA.

4. Ukugcinwa: igeyiji yoxinzelelo olwahlukileyo + ukutshintshwa rhoqo

• Ukusetyenziswa kwekhaya: Buyisela indawo nganye kwiinyanga ezi-6-12, okanye utshintshe xa umahluko woxinzelelo ngu>150 Pa.

• Imizi-mveliso: Linganisa umahluko woxinzelelo rhoqo ngenyanga, kwaye uwubuyisele ukuba ngu > 2 umphinda-phindene wokuxhathisa kwasekuqaleni.

• Iyahlambeka? Kuphela iiHEPA ezimbalwa ezigqunywe nge-PTFE zinokuhlanjwa kancinci, kwaye ifayibha yeglasi iya kutshatyalaliswa xa idibana namanzi. Nceda ulandele imiyalelo.

5. Iimeko zesicelo ezidumileyo ngo-2025

• I-Smart Home: Iitshayela, izifudumezi zomoya, kunye nezinto zokufumisa zonke zixhotyiswe nge-H13 njengesiqhelo.

• Izithuthi zamandla amatsha: I-H14 cabin air conditioning filter element ibe yindawo yokuthengisa kwiimodeli eziphezulu.

• Ezonyango: Ikhabhathi ye-PCR ehambayo isebenzisa i-U15 ULPA, enezinga lokugcinwa kwentsholongwane ka-99.9995% ngaphantsi kwe-0.12 µm
