Lapho uthenga isomisi sesandla se-FEEGOO , uzohlala uzwa igama elithi “HEPA filter” lishiwo abathengisi, kodwa abantu abaningi abakakwazi okuningi ngesihlungi se-HEPA, futhi ukuqonda kwabo ngaso kusala kusezingeni elikha phezulu “lesihlungi esithuthukisiwe” .izinga.

Siyini isihlungi se-HEPA esomisa isandla?

Isihlungi se-HEPA sibizwa nangokuthi isihlungi se-HEPA esisebenza kahle kakhulu, igama eliphelele lesiNgisi elithi High-efficiency particulate arrestance.

Izihlungi ze-HEPA ngokuvamile zenziwe nge-polypropylene noma ezinye izinto eziyinhlanganisela, futhi eziningi zazo aziwasheki.Inani elincane lezihlungi ze-HEPA ezenziwe nge-PET zingagezwa ngamanzi, kodwa umphumela wokuhlunga wezihlungi ezinjalo uphansi.

Izihlungi eziningi ze-HEPA ezisetshenziswa ohlelweni lomoya omusha zinjengoba kukhonjisiwe ngezansi.Ukuze kwandiswe umthamo wazo wokubamba uthuli, inqwaba yokugoqa kuyagoqwa, futhi ukuthungwa kuzwakala kufana nephepha eliwugqinsi.

Sisebenza kanjani isihlungi se-Jet Hand dryer HEPA?

Izihlungi ze-HEPA zihlunga ngezindlela ezi-4: ukucasha, amandla adonsela phansi, ukugeleza komoya namandla e-van der Waals

1 Indlela yokuhlukanisa isisefo esiqondwa yiwo wonke umuntu.Ngokuvamile, izinhlayiya ezinkulu ze-5 μm kanye ne-10 μm ziyabanjwa futhi "zihlungiwe".

2. Ngaphansi kwethonya lamandla adonsela phansi, izinhlayiya zothuli ezinomthamo omncane kanye nokuminyana okuphezulu zizonciphisa isivinini sazo lapho zidlula ku-HEPA, futhi zizohlala ngokwemvelo kusihlungi se-HEPA njengenhlabathi ecwila phansi emfuleni.

3 Isikrini sokuhlunga silukwe ngokungalingani ukuze sakhe inani elikhulu lama-air vortices, futhi izinhlayiya ezincane zikhangiswa kusikrini sesihlungi se-HEPA ngaphansi kwesenzo sesishingishane sokugeleza komoya.

4 Izinhlayiya ze-ultrafine zenza ukunyakaza kwe-Brownian ukuze zishaye ungqimba lwefayibha ye-HEPA, futhi zihlanzwa ngomthelela we-van der Waals force.Isibonelo, abathwali begciwane ngaphansi kwe-0.3 μm bayahlanzwa ngaphansi kwethonya lamandla.

I-Van der Waals force: amandla e-intermolecular, abhekisela emandleni akhona phakathi kwama-molecule (i-molecule) nama-molecule noma phakathi kwamagesi ahloniphekile (igesi elihle) nama-athomu (ama-athomu).

Isilinganiso sesihlungi se-HEPA

Ngihlale ngizwa othile ethi “isihlungi engisisebenzisayo i-H12″, manje liyini izinga lokuhlola elithi “H12″ lapha?

Ngokwezinga le-EU EN1882, ngokokusebenza kokuhlunga, sihlukanisa isihlungi se-HEPAl sibe amabanga ama-5: isihlungi esimahhadla, isihlungi esisebenza kahle esimaphakathi, isihlungi esisebenza kahle kakhulu, isihlungi se-HEPA esisebenza kahle kakhulu nesihlungi esisebenza kahle kakhulu.

Isihlungi esinekhono lokuhlunga elingaphezu kuka-99.9% sezinhlayiyana ezinosayizi wezinhlayiyana ongu-0.3 μm sibizwa ngokuthi i-H12.

Ukungaqondi Okujwayelekile Kwezihlungi Ze-HEPA Zokomisa Isandla

Inganekwane 1: Uma umthamo wezinhlayiya umkhulu, kuba lula ukususwa yi-HEPA?

Ukuhlaziya: Umgomo wokuhlanza wesihlungi se-HEPA awukona nje ukuhlunga izinhlayiya ezinkulu kunemeshi njengesisefo ukuze kuhlanzeke umoya.Kunalokho, ithembele emandleni e-van der Waals phakathi kwezinhlayiya ezinhle nesihlungi ukuze kwakhe umphumela we-adsorption, futhi inokuhlunga okuhle kwezinhlayiya ezingaphezu kuka-0.5 μm nangaphansi kuka-0.1 μm.

Izinhlayiya ezingaphansi kuka-0.1 μm zenza ukunyakaza kwe-Brownian.Uma izinhlayiya ziyincane, kulapho ukunyakaza kwe-Brownian kuba namandla, futhi lapho kushaywa izikhathi eziningi, kuba ngcono umphumela we-adsorption.

Futhi izinhlayiya ezingaphezulu kuka-0.5μm zenza ukunyakaza kwe-inertial, ubukhulu obukhulu, i-inertia enkulu, futhi umphumela wokuhlunga ube ngcono.

Ngokuphambene, izinhlayiya ezinobubanzi obungu-0.1-0.3 μm kube nzima ukususa i-HEPA.Yingakho imboni ichaza ibanga lesihlungi se-HEPA ngezinga lokuhlunga lezinhlayiya ezingu-0.3μm.

Ukungaqondi kahle 2: Ukusebenza kahle kokuhlanzwa kwe-HEPA ye-0.3μm microparticles kungafinyelela ngaphezu kwe-99.97%, ngakho-ke umphumela wayo wokuhlanza kuma-microparticles angu-0.1μm awuqinisekile, akunjalo?

Ukuhlaziya: Ngendlela efanayo nokungaqondi kahle, i-PM0.3 kulula ukugqobhoza ekuvikelekeni kwesihlungi se-HEPA, ngoba ayingenwa kalula nomthelela we-van der Waals force.Ngakho-ke, isihlungi esinomphumela ongu-99.97% ku-PM0.3 singasebenza kangcono ku-PM0.1.Nokho, ngisho 99.99%.

Inganekwane yesi-3: Uma iphezulu ukusebenza kahle kokuhlunga kwe-HEPA, kungcono?

Ukuhlaziya: Noma yini inkulu kakhulu.Ukuphakama kokuhlunga kwe-HEPA, kukhulu ukumelana, futhi umthamo wangempela wokungenisa umoya uzoncishiswa.Lapho ivolumu yomoya iyancipha, inani lokuhlanzwa ngesikhathi seyunithi lizokwehla, futhi ukusebenza kahle kokuhlanza kuzokwehla.

Ngakho-ke, inhlanganisela enengqondo kuphela ye-fan, isihlungi kanye nomklamo wokujikeleza komoya ongafinyelela imodeli enhle kakhulu.

Isihlungi se-HEPA esomisa isandla kufanele sishintshwe kangaki?

Okokugcina, sibuyela embuzweni wonke umuntu akhathazeke ngawo, ingabe isihlungi se-HEPA sidinga ukushintshwa kangaki?

Inkomba eyinhloko yokwahlulela impilo yesevisi yesihlungi umthamo wokubamba uthuli.Idatha eyinhloko ethinta umthamo wokubamba uthuli indawo enwetshiwe yesikrini sokuhlunga.Uma indawo enwetshiwe yesikrini sokuhlunga iba nkulu, ikhulisa umthamo wokubamba uthuli futhi isikrini sokuhlunga sihlala isikhathi eside.

Umthamo wokubamba uthuli ubhekisela enanini lokuqoqwa kothuli lapho ukumelana ngenxa yokuqoqwa kothuli kufinyelela inani elishiwo (ngokuvamile izikhathi ezingu-2 ukumelana kokuqala) ngaphansi kwesenzo somthamo othile womoya.

Kodwa kubasebenzisi abajwayelekile, isisekelo sokwahlulela ukushintshwa kwesihlungi ukubuka ngeso lenyama.

Akuyona isayensi ukwahlulela ukuthi isihlungi kufanele sishintshwe indlela yokubuka ngeso lenyama.Ingase isisebenzise ngokweqile isihlungi, ibangele ukungcoliswa kwesibili, futhi ingase “iyeke” isihlungi kusengaphambili ngaphandle kokukhulisa inani laso lokusetshenziswa.

I-FEEGOO isebenzisa i-algorithm ye-Gaussian efiphele ukubala ukukhishwa kothuli okunqwabelene kwesihlungi, futhi incoma ukuthi amakhasimende amiselele isihlungi esisebenza kahle kakhulu esomiso sesandla kanye njalo ezinyangeni eziyisithupha.
