Mpweya wodutsa mpweya umagwirizanitsa mpweya wamkati ndi mpweya wakunja.Ogwira ntchito m'nyumba amatha kusangalala ndi kutentha kosiyanasiyana komwe kumayendetsedwa ndi dongosolo, kaya nthawi yachilimwe kapena yozizira.Kuyenda kwa mpweya sikungachepetse kufala kwa matenda komanso kumapindulitsa thupi ndi maganizo.Chifukwa chake, mabizinesi ndi mafakitale nthawi zambiri amagwiritsa ntchitokupezeka kwa mpweyakukhathamiritsa malo okhala m'nyumba, zomwe zimakulitsa luso la ogwira ntchito.

Chifukwa cha zomwe msika umakonda pazinthu zowunikira komanso kulimbikitsa kwambiri chitetezo cha chilengedwe, ma ducts a nsalu adayamba kukhala.Malinga ndi kusanthula kwa deta yamsika, kukula kwapachaka kwa ma ducts a mpweya akuti kupitilira 3% m'zaka zisanu zikubwerazi.Izi zikuwonetsa kuti msika wa ma ducts a nsalu ukukula mwachangu ndipo uli ndi kuthekera kwakukulu.Ma ducts ansalu omwe amapangidwa kwambiri ndi ulusi wa poliyesitala ndi ulusi wamagalasi amakhala ndi mawonekedwe opepuka, omwe amagwirizana ndi zomwe zikuchitika komanso zamtsogolo zanyumba zopepuka kuti zichepetse kulemetsa kwa zomangamanga.Ndipo zinyalala pulasitiki akhoza recycled mu zopangira nsalu ducts, amene amakwaniritsa chitukuko zisathe mkombero ndi zikugwirizana ndi panopa kutetezedwa kwa chilengedwe.

Kupatula apo, ntchito zosinthidwa makonda zabweretsa mwayi watsopano komanso mphamvu pamakampani opanga ma ducts a nsalu.Kumbali imodzi, mitundu ingapo yosankhika ya ma ducts a nsalu imatha kusintha momwe wantchitoyo amakhalira m'malo osiyanasiyana ogwirira ntchito poyerekeza ndi kamvekedwe kake kazitsulo zolowera mpweya.Ndipo mapangidwe ndi logos akhoza kusinthidwa ndi kusindikizidwa pazitsulo za nsalu, zomwe zimasonyezanso nzeru za kampani ndi makhalidwe ake ndipo zimakhala ndi zotsatira zabwino pamaganizo a antchito.

Kumbali ina, makulidwe osiyanasiyana ndi mawonekedwe osiyanasiyana a mabowo pazitsulo za nsalu amathanso kusinthidwa kuti apereke chidziwitso chomasuka malinga ndi mawonekedwe a malo.Ma ducting a nsalu ndi ma diffuser amatha kuwongolera kuchuluka kwa mpweya ndi mayendedwe pogwiritsa ntchito nsalu yopumira, mabowo ang'onoang'ono, mabowo ang'onoang'ono, ma nozzles kuti mpweya wabwino ndi woyera ugawidwe kumakona onse a danga popanda "zigawo zakufa".

Ma ductwork a nsalu amakhala ndi magwiridwe antchito apamwamba kwambiri, ndiye kuti muyenera kukhala ndi chidwi ndi kukonza kwa ma ducting a nsalu, makamaka Perforating.Makina a laser amatha kuthetsa vuto la perforating la ma ducts a nsalu.Chifukwa chaukadaulo wapamwamba kwambiri komanso ukadaulo wopangira matenthedwe, makina a laser amatha kudula mabowo osiyanasiyana ndi ma nozzles okhala ndi m'mphepete mwaukhondo komanso osalala malinga ndi zosowa zosiyanasiyana za opanga kuti apereke ntchito yoyenera kwambiri.Ndife okondwa kukuthandizani ngati mukufuna kuphunzira zambiri za makina a laser ndi kukonza ma ducts a nsalu.
