Nzvimbo dzakawanda uye dzakawanda dzinofanirwa kuwana mhepo munzvimbo dzakavharirwa, kuitira kuti ive nechokwadi chekuchengetedza uye hutano hwevashandi uye kushanda zvakajairwa.Conventionalpedza mafeniuyenegative exhaust mafeni (maindasitiri anopedza mafeni)midziyo yakajairika yekufefetera, uye inowanzoshandiswa kuenzanisa.Kuenzaniswa neyakajairwa exhaust mafeni, ndeipi inonyanya kusiyanisa?
Kuenzaniswa neyakajairwa exhaust mafeni,negative exhaust mafeni (industrial exhaust fans)vane zvakanakira zviri pachena:
1. Hunhu hwechigadzirwa hwakanaka kwazvo, uye kushanda kuri nyore uye kuri nyore.Kana mapofu emaoko achishandiswa kutonga, hazvizokanganisa zvakananga kutenderera kwechiedza uye kufefetera mhedzisiro kana shutter isina kuvhurwa.
2. Mhepo yekubuda kwemhepo yemuchina wayo mumwe yakakura kwazvo, uye inovhara huwandu hwakawanda.Panguva imwecheteyo, iyo yakaipa yekupedza fan ine mabasa maviri emhepo uye kutonhora.Kuishandisa mupurojekiti yekufefetera uye yekutonhodza kunogonawo kuderedza bhajeti remari yeprojekiti.
3. Mashizha eFani anowanzo kugadzirwa nesimbi isina tsvina kana akakanda aluminium blades, iyo inogona kumira zvakanyanya-yakakwirira tembiricha uye isingatani kukanganisa uye kuchembera.
Naizvozvo, mafeni ekunze asina kunaka (maindasitiri ekupedza mafeni) anonyanya kushanda kana akashandiswa munzvimbo dzakakura-nzvimbo yekufefetera, uye mafeni madiki emhepo anonyanya kukodzera kufefetera mudzimba dzekugezera, makicheni epamba uye dzimwe nzvimbo.Negative exhaust fan (industrial exhaust fan) inokodzera kufefetera hombe kusimudzira kutenderera kwemhepo, kuitira kuti uwane chinangwa uye mhedzisiro yemhepo uye kuendesa mweya mutsva.
