Hais txog cov qauv ntawm cov lim cua, txhua lub teb chaws thiab cheeb tsam muaj cov qauv sib xws. Hauv kev lag luam thoob ntiaj teb, txhua tus yuav tsum tau lees paub cov qauv tsim nyog thiab lees paub qhov tseeb lim efficiency ntawm cov khoom.
Filter efficiency test method standard:
Tebchaws Asmeskas yog thawj zaug ua cov txheej txheem kev ntsuas huab cua lim. Xyoo 1999, American ASHRAE Association's CLMH-UH efficiency classification
Muaj ntau txoj kev sim:
1. Kev raug ntes
Qhov kev kuaj plua plav qhov chaw yog loj-particle, high-concentration standard plua plav. Arizona Road Plua plav los ntawm Arizona tau siv hauv Asmeskas kev xeem. Qhov hnyav ntawm qhov ntsuas plua plav tuav los ntawm lub lim yog hu ua "dust tuav peev".
Cov qauv tsim nyog: American Ansi/ashrae 52.1-1992, European EN 779: 1993, Suav GB12218-89
2. Particle Efficiency
Cov cuab yeej rau ntsuas plua plav yog lub laser particle txee. Qhov ua tau zoo tam sim no ntawm txhua theem yog ntsuas ntau zaus raws li qhov hnyav nruab nrab ntawm cov hmoov av tsim.
Cov qauv tsim nyog: European Eurovent 4/9-1993 American ASHRAE 52.2-1999
Lwm cov qauv muaj xws li: Txoj Kev Sodium Flame method, Sodium Flame method, DOP method, thiab lwm yam.
Raws li lub tuam txhab muaj kev lav phib xaub, SAF tau sau cov ntaub ntawv sib txawv thiab cov duab kos los tsim cov qauv sib piv rau txhua cheeb tsam rau txhua tus neeg siv.
Yog tias koj txaus siab, thov koj xav qhia rau kuv paub thiab paub meej ntxiv, thov hu rau peb.
