Izihlungi Zomoya Zemishini

• Izihlungi ziqukethe imidiya enezimbobo zemicu yezintambo noma izinto zolwelwesi olululiwe ukuze zikhiphe izinhlayiya emifuleni yomoya.
• Ezinye izihlungi zineshaji kagesi emile esetshenziswa kwabezindaba ukuze kwandiswe ukukhishwa kwezinhlayiyana.Njengoba ukusebenza kahle kwalezi zihlungi kuvame ukwehla phakathi nezinyanga zokusetshenziswa kokuqala, inani le-MERV-A, uma litholakala, lizobonisa ukusebenza kahle okuncane kwangempela kunevelu ye-MERV evamile.
• Ingxenye yezinhlayiya ezikhishwe emoyeni ezidlula isihlungi ibizwa ngokuthi "ukusebenza kahle kwesihlungi" futhi inikezwa yi-Inani Elincane Lokubika Ukusebenza kahle (MERV)ngaphansi kwezimo ezijwayelekile.Ezinye izihlungi zineshaja kagesi emile esetshenziswa kwabezindaba ukuze kwandiswe ukukhishwa kwezinhlayiyana.Njengoba ukusebenza kahle kwalezi zihlungi kuvame ukwehla phakathi nezinyanga zokusetshenziswa kokuqala, inani le-MERV A, uma litholakala, lizobonisa ukusebenza kahle okuncane kwangempela kunevelu ye-MERV evamile.
  • I-MERV isukela ku-1 kuye ku-16;i-MERV ephezulu = ukusebenza kahle okuphezulu
  • I-MERV ≥13 (noma i-ISO elingana) iyasebenza ekubambeni amagciwane asemoyeni
  • Izihlungi ze-MERV 14 (noma ezilingana ne-ISO) ziyakhethwa
  • Izihlungi ze-particulate air (HEPA) ezisebenza kahle kakhuluzisebenza kahle kakhulu kunezihlungi ze-MERV 16.
• Ukusebenza kahle kwesihlungi ngokuvamile kubangela ukwehla kwengcindezi ngesihlungi.Qinisekisa ukuthi amasistimu e-HVAC angakwazi ukusingatha ukuthuthukiswa kwesihlungi ngaphandle kwemithelela engemihle ekuhlukeni kwengcindezi kanye/noma amazinga okugeleza komoya ngaphambi kokushintsha izihlungi.
• Ngokuvamile, izinhlayiya ezinobubanzi be-aerodynamic ezizungeze u-0.3 μm zingena kakhulu;ukusebenza kahle kuyanda ngenhla nangaphansi kwalo sayizi wezinhlayiyana.
• Ukusebenza sekukonke kokunciphisa ukugxila kwezinhlayiyana kuncike ezintweni ezimbalwa:
  • Ukusebenza kahle kwesihlungi
  • Izinga lokugeleza komoya ngesihlungi
  • Ubukhulu bezinhlayiya
  • Indawo yesihlungi ohlelweni lwe-HVAC noma isicoci somoya segumbi

I-ASHRAE Standard 52.2-2017 Inani Elincane Lokubika Ukusebenza Kahle (MERV)

SHRAE MERV vs. ISO 16890 Izilinganiso

Izihlungi ze-HEPA

• Ngokwencazelo, izihlungi ze-HEPA zangempela okungenani zisebenza kahle ngo-99.97% ekuhlungeni izinhlayiya ezingu-0.3 μm mass median diameter (MMD) ekuhlolweni okujwayelekile.
• Iningi losayizi wezinhlayiyana ezingenayo lingase libe lincane kuno-0.3 μm, ngakho-ke ukusebenza kahle kokuhlunga kwezinhlayiya eziningi ezingenayo kungaba ngaphansi kancane.

• Ukusebenza kahle kwesihlungi se-HEPA kungcono kune-MERV 16.
• Izihlungi ze-HEPA zingase zingabi inketho efanelekile kwabanye kumasistimu e-HVAC ngenxa yokwehla kokucindezela okukhulu kanye nethuba lokuthi amasistimu azodinga ama-rack okuhlunga amasha ukuze avumele ukuvala okwanele ukuze kuvinjelwe ukudlula isihlungi.
• Ukuze zisebenze kahle, izihlungi ze-HEPA kufanele zivalwe kahle kuma-rack racks.
• Izihlungi zivame ukuthambile futhi zidinga ukuphathwa ngokucophelela ukuvimbela ukulimala nokugcina ukusebenza.
• Izihlungi ze-HEPA zingatholakala ezinhlelweni ze-HVAC noma ku:
  • Ekamelweni noma Imishini Ephathwayo ye-HEPA
  • Amasistimu Ahlanganiswe Ngaphambili
  • Imihlangano ye-Ad Hoc

Izihlungi zomoya ze-Electronic

• Bandakanya izinhlobonhlobo zemishini yokuhlanza umoya exhunywe ngogesi eklanyelwe ukususa izinhlayiya emisakazweni yomoya.
• Ukususwa ngokuvamile kwenzeka ngezinhlayiya ezishaja ngogesi kusetshenziswa izintambo ze-corona noma ngokukhiqiza ama-ion (isb, ama-pin ionizers), futhi:Ingxenye yezinhlayiyana ezikhishwa emoyeni ngesihlungi se-elekthronikhi ibizwa ngokuthi “ukusebenza kahle kokususa.”
  • Iqoqa izinhlayiya kumapuleti ashajwe ngokuphambene (ama-precipitator, ESP), noma
  • Ukususwa okuthuthukisiwe kwezinhlayiya ezishajiwe ngesihlungi somoya esiyimishini, noma
  • Ukubekwa kwezinhlayiya ezishajiwe endaweni yegumbi.
• Ukuphumelela sekukonke kokunciphisa ukugxila kwezinhlayiyana kuncike kokuthi:Kubalulekile ukusula izintambo kuma-electrostatic precipitators njengoba i-silicone buildup inciphisa ukusebenza kahle.
  • Ukususa ukusebenza kahle
  • Izinga lokugeleza komoya ngesihlungi
  • Usayizi nenani lezinhlayiya
  • Indawo yesihlungi kusistimu ye-HVAC
  • Ukugcinwa nokuhlanzeka kwezingxenye zokuhlunga zikagesi
• Hlala ulandela imiyalelo yomkhiqizi lapho usebenzisa izihlungi zomoya ezisebenza ngogesi.

I-Gas-Phase Air Cleaners

• Izihlanzi komoya zesigaba segesi yilezo ezisetshenziselwa ukususa i-ozone, izakhi eziphilayo eziguquguqukayo kanye nephunga elivela emoyeni.
• Eziningi ziqukethe izinto ezi-sorbent njenge-carbon (isb, amalahle acushiwe).
• Nakuba kungase kube khona okuhlukile,iningiimibhede ye-sorbent iyodwa ngokuvamile ayisebenzi kahle ekususeni amagciwane emifuleni yomoya.
• Izihlungi zefayibha ezifakwe ngekhabhoni/i-sorbent zizosusa izinhlayiya;hlola isilinganiso se-MERV ukuze ubonise ukusebenza kahle njengoba wenza ngezihlungi ze-particle ejwayelekile.

Imikhiqizo yokuhlunga komoya ye-Holtop ye-anti-virus:

1. I-ventilator yokubuyisela amandla enesihlungi se-HEPA

2. Ibhokisi le-UVC + photocatalysis filter air disinfection

3. Isihlanzi somoya esisha sobuchwepheshe obusha esifinyelela ku-99.9% izinga lokubulala amagciwane

4.Izixazululo zokubulala amagciwane emoyeni ezenziwe ngokwezifiso
