Momwe mafani a ziweto angayendetsere chitukuko cha zoweta

Ziweto ndizofunikira kwambiri paulimi ndipo zimagwira ntchito yofunika kwambiri pakupanga chakudya. Komabe, kuonetsetsa malo abwino okhalamo ziweto ndikofunikira kwambiri kuti zikhale ndi thanzi komanso moyo wabwino. M'zaka zaposachedwa, makampani obereketsa akukumana ndi zovuta chifukwa cha malo opanda mpweya komanso otsekedwa, zomwe zimapangitsa kuti pakhale mpweya woipa komanso zinthu zina zomwe zimachititsa kuti ziweto zizidwala matenda osiyanasiyana. Pofuna kuthana ndi mavutowa, anthu okonda ziweto atulukira njira yabwino yopititsira patsogolo ulimi.

Fani yazifuyo, yomwe imadziwikanso kuti negative pressure fan, ndi chida chopangira mpweya wabwino chomwe chimagwiritsidwa ntchito kwambiri poyambitsa mpweya wabwino komanso kuziziritsa. Amapangidwa kuti athetse vuto la mpweya wabwino komanso kuziziritsa. Mafani awa ali ndi mawonekedwe apadera monga kukula kwakukulu, njira yayikulu yowonjezeramo mpweya, mainchesi amtundu wokulirapo, komanso kuchuluka kwa mpweya wowonjezera. Kuphatikiza apo, amadziwika chifukwa cha kuchuluka kwa mpweya wawo, kugwiritsa ntchito mphamvu kwambiri, kuthamanga kwambiri komanso phokoso lochepa.

Zikafika pazinthu zamapangidwe, mafani a ziweto amatha kugawidwa m'magulu awiri akuluakulu: mafani amphamvu amtundu wa square negative ndi mafani amphamvu a fiberglass ngati lipenga. Mafanizi amapanga malo oponderezedwa olakwika mkati mwa malo a ziweto. Potulutsa mpweya kunja, kuthamanga kwa mpweya wamkati kumachepa, zomwe zimapangitsa kuti mpweya wamkati usinthe. Izi, zimapanganso malo oponderezedwa olakwika omwe amakokera mpweya wabwino m'chipindamo chifukwa cha kusiyana kwapakati.

Pogwiritsira ntchito, mafani a ziweto amayikidwa bwino m'mafakitale, nyama zoweta zimayang'ana mbali imodzi ya nyumbayo. Mpweya wa mpweya uli mbali inayo, zomwe zimapangitsa kuti mpweya wabwino uziyenda bwino mumlengalenga. Mothandizidwa ndi mafani a ziweto, kuwomba kwa convection kumatheka kuti mpweya uziyenda mwadongosolo. Panthawiyi, zitseko ndi mazenera pafupi ndi fanizi zimakhala zotsekedwa pamene mpweya wokakamiza umalowa mu fani.
