Kufananidzwa kuongororwa kwemhepo filtration mazinga pakati peAmerica uye European zviyero

W hen inofananidza mhepo filtration mazinga pakati peAmerica uye European zviyero, mutsauko unoverengeka unogona kuzivikanwa. Misiyano iyi inonyanya kutenderedza nzira dzekuyera, tsika dzekuenzanisa, uye zvidiki zvinodiwa kuti mhepo filtration.

1. Kuyera nzira:
- American Standard: The American Society yekupisa, rinofemha, uye mainjiniya emhepo (ashrae) anoshandisa kukosha kwekushanda kwakashata (Merv) senzira yekuyera. Merv anotora mafirita pachiyero che1 kusvika ku20, ane manhamba akakwira achiratidza zviri nani kuedza kwekusakwana.
- European Standard: CommEan yeEuropean yekuregerera (CEN) inoshandisa iyo European Norm (en) 779 neEn 1822 sekuyera nzira. En 779 mitengo yemafirita pachiyero cheG1 kusvika F9, ine manhamba akakwira anoratidza zvirinani kuedza kwetsika. En 1822 inoyera nekubudirira kwekunyanyisa-kugona kwekushanda mhepo (hepa) mafirita.

2. Kugadziriswa masisitimu:
- American Standard: Ashrae inoratidza mafirita mumapoka matatu makuru: Chikamu chimwe nechimwe chine subcategories zvichibva pane merv ratings.
- European Standard: Cen inozivisa mafirita mumapoka matatu makuru: coarse, zvakanaka, uye hepa. Chikamu chimwe nechimwe chine subcategoriories zvichienderana ne eng ratings.

3. Zvishoma zvinodiwa:
- American Standard: Ashrae anokurudzira kushoma merv 6 chiyero cheMalidential application uye Merv 13 yezvivakwa zvekutengeserana. Nekudaro, aya anongovara chete, uye hapana zvinodiwa zvekumanikidza kuti zvive zvemhepo kuyerera muUnited States.
- European Standard: Cen inochengetera zvidiki zvinodiwa zveMhepo Filtration mune zvimwe zvekushandisa. Semuenzaniso, en 779 inoda chiyero chidiki cheG4 kuti general Wentilation Mafirita, nepo en 1822 inotsanangura huwandu hushoma hwekugona kweHEPA mafirita.

Izvo zvakakosha kuti zviitike kuti zviyero izvi hazvina kufanana zvakananga, sezvo vane nzira dzakasiyana dzekuyera, kurongedza masisitimu, uye zvidiki zvinodiwa. Nekudaro, kuedza kuri kuitwa kuwiriranisa izvi zviyero kuti zviitise kuenzanisa kwepasi rese uye kuve nechokwadi chekuchinja kwemhepo filtration pasi pasi.
