AIRHEAD: Mutha kunena molimba mtima kuti njira yopangira ma ducts ndi yothandiza ngati mpweya woyezedwa ndi ± 10% wa mpweya wowerengeka.
Ma ducts a mpweya ndi chimodzi mwazinthu zofunika kwambiri pakupanga mpweya wabwino komanso mpweya wabwino. High Performance HVAC Systems ikuwonetsa kuti zinthu 10 zimagwirira ntchito limodzi kuti zitsimikizire momwe ma duct amagwirira ntchito. Ngati chimodzi mwazinthu izi chimanyalanyazidwa, dongosolo lonse la HVAC silingakupatseni chitonthozo ndi luso lomwe mukuyembekezera kwa makasitomala anu. Tiyeni tiwone momwe zinthuzi zimakhudzira momwe ma duct system amagwirira ntchito komanso momwe mungatsimikizire kuti ndi zolondola.
Mafani amkati (owombera) ndi pomwe mawonekedwe a ma ducts a mpweya amayamba. Imatsimikizira kuchuluka kwa mpweya womwe pamapeto pake ungayendere kudzera munjirayo. Ngati kukula kwa duct kumakhala kochepa kwambiri kapena koyikika molakwika, wowotchayo sangathe kupereka mpweya wofunikira kudongosolo.
Kuti muwonetsetse kuti mafani ndi amphamvu mokwanira kuti asunthire mpweya wofunikira, muyenera kutchula tchati cha fan cha chipangizocho. Zambirizi zitha kupezeka m'malangizo a wopanga kapena chidziwitso chaukadaulo. Yang'anani kwa izo kuti muwonetsetse kuti zimakupiza zimatha kuthana ndi kukana kwa mpweya kapena kutsika kwamphamvu pamakoyilo, zosefera ndi ma ducts. Mudzadabwa ndi zomwe mungaphunzire kuchokera ku chidziwitso cha chipangizo.
Koyilo yamkati ndi fyuluta ya mpweya ndizo zigawo ziwiri zazikulu za dongosolo lomwe fani iyenera kudutsa mpweya. Kukana kwawo kwa mpweya kumakhudza mwachindunji ntchito ya duct. Ngati ali oletsa kwambiri, amatha kuchepetsa kwambiri mpweya usanachoke pagawo la mpweya wabwino.
Mutha kuchepetsa mwayi wodula makholo ndi zosefera pochita ntchito pang'ono pasadakhale. Onani zambiri za wopanga koyilo ndikusankha koyilo yamkati yomwe ipereka mpweya wofunikira ndi kutsika kotsika kwambiri konyowa. Sankhani fyuluta ya mpweya yomwe imakwaniritsa zosowa za makasitomala anu paumoyo ndi ukhondo pomwe mukusunga kutsika kwapang'onopang'ono komanso kuthamanga kwamayendedwe.
Kuti ndikuthandizeni kukula bwino fyuluta yanu, ndikufuna ndikupatseni lingaliro la National Comfort Institute (NCI) "Filter Sizing Program". Ngati mukufuna kope la PDF chonde nditumizireni imelo.
Kukonzekera bwino kwa mapaipi ndi maziko opangira mapaipi. Umu ndi momwe njira yoyikidwira idzawoneka ngati zidutswa zonse zigwirizana monga momwe zimayembekezeredwa. Ngati mapangidwewo ali olakwika kuyambira pachiyambi, ntchito ya ductwork (ndi dongosolo lonse la HVAC) likhoza kuvutika chifukwa cha kutumiza mpweya wosayenera.
Akatswiri ambiri m'makampani athu amaganiza kuti kapangidwe kabwino ka ma ducts amafanana ndi momwe ma duct system amagwirira ntchito, koma sizili choncho. Kuti muwonetsetse kuti njira yanu yopangira ma ducts ndi yothandiza, ziribe kanthu kuti itani, muyenera kuyeza mpweya weniweni wa dongosolo lanu lomanga. Ngati mpweya woyezedwa ndi ± 10% wa mpweya wowerengeka, mutha kunena molimba mtima kuti njira yanu yowerengera imagwira ntchito.
Kuganiziranso kwina kumakhudza mapangidwe a zida zopangira mapaipi. Kusokonekera kwakukulu chifukwa cha zomangira zosapangidwira bwino kumachepetsa kuyenda bwino kwa mpweya ndikuwonjezera kukana komwe fani iyenera kuthana nayo.
Zopangira ma air duct ziyenera kutulutsa pang'onopang'ono komanso kosalala kwa mpweya. Pewani kutembenukira kwakuthwa ndikuchepetsa kuyika mapaipi kuti muwongolere magwiridwe antchito awo. Kuwunika mwachidule kwa ACCA Handbook D kukuthandizani kusankha kasinthidwe koyenera komwe kangakhale koyenera. Zosakaniza zokhala ndi utali wofanana ndi zazifupi zimapereka mpweya wabwino kwambiri.
Dongosolo lolimba la ma ducts limapangitsa kuti mpweya uziyenda ndi fan mkati mwa ducts. Mapaipi otayirira amatha kusokoneza magwiridwe antchito ndikuyambitsa mavuto osiyanasiyana, kuphatikiza IAQ ndi CO chitetezo, ndikuchepetsa magwiridwe antchito.
Kuti zikhale zosavuta, zolumikizira zamakina zilizonse pamapaipi ziyenera kusindikizidwa. Putty imagwira ntchito bwino ngati palibe chifukwa chosokoneza kulumikizana, monga chitoliro kapena kulumikiza mapaipi. Ngati pali chigawo kumbuyo kwa makina olumikizirana omwe angafunikire kukonzanso mtsogolo, monga koyilo yamkati, gwiritsani ntchito chosindikizira chosavuta chochotseka. Osamatira ntchito pa mapanelo a zida zolowera mpweya.
Mpweya ukakhala munjira, umafunika njira yowuwongolera. Ma damper a Volumetric amakulolani kuti muwongolere njira yoyendetsera mpweya ndipo ndizofunikira kwambiri pakuchita bwino kwadongosolo. Machitidwe opanda zochepetsera zambiri amalola mpweya kutsatira njira yochepetsera kukana.
Tsoka ilo, okonza ambiri amawona kuti zowonjezera izi ndizosafunikira ndikuzichotsa pamayikidwe ambiri a mapaipi. Njira yolondola yochitira izi ndikuwalowetsa m'nthambi zoperekera ndikubwezeretsanso kuti muthe kuwongolera kutuluka kwa mpweya mkati ndi kunja kwa chipinda kapena malo.
Mpaka pano, tangoyang'ana mbali ya mpweya. Kutentha ndi chinthu china chogwiritsira ntchito mapaipi omwe sayenera kunyalanyazidwa. Ma ducts a mpweya opanda zotchingira sangapereke kuchuluka kwa kutentha kapena kuziziritsa kofunikira m'zipinda zokhala ndi mpweya.
Kusungunula kwa duct kumasunga kutentha kwa mpweya mkati mwa duct m'njira yoti kutentha komwe kumatulukako kumakhala pafupi ndi komwe wogula angamve potuluka.
Kusungunula kuikidwa molakwika kapena ndi mtengo wotsika wa R sikungalepheretse kutaya kutentha mu chitoliro. Ngati kusiyana kwa kutentha pakati pa kutentha kwa chipinda chogulitsira ndi kutentha kwa mpweya kumapitirira 3 ° F, kutsekemera kwa mapaipi kungafunike.
Marejista a chakudya ndi ma grill obwerera ndi gawo lomwe nthawi zambiri limamanyalanyazidwa pakugwira ntchito kwa mapaipi amadzi. Nthawi zambiri opanga amagwiritsa ntchito zolembera zotsika mtengo komanso ma grilles. Anthu ambiri amaganiza kuti cholinga chawo chokha ndikutseka mipata yazakudya ndi kubweza, koma amachita zambiri.
Kaundula wopereka amawongolera kuperekedwa ndi kusakanikirana kwa mpweya wokhazikika m'chipindamo. Ma grilles obwereranso samakhudza kayendedwe ka mpweya, koma ndi ofunikira ponena za phokoso. Onetsetsani kuti sakuyimba kapena kuyimba pomwe mafani akuthamanga. Onani zambiri za wopanga kabati ndikusankha kaundula yemwe amagwirizana bwino ndi kayendedwe ka mpweya ndi chipinda chomwe mukufuna kuwongolera.
Chosiyana chachikulu pakuzindikira magwiridwe antchito a mapaipi ndi momwe mapaipi amayikidwira. Ngakhale dongosolo labwino likhoza kulephera ngati litayikidwa molakwika.
Kusamala tsatanetsatane ndi kukonzekera pang'ono kumapita kutali kuti mupeze njira yoyenera yoyika. Anthu adzadabwitsidwa akawona kuchuluka kwa mpweya womwe ungapezeke kuchokera ku ma ducting osinthika mwa kungochotsa pachimake chowonjezera ndi kinks ndikuwonjezera chopachika. Zomwe zimachitika ndi reflex ndikuti mankhwalawo ndi omwe ali ndi mlandu, osati oyika omwe akugwiritsidwa ntchito. Izi zikutifikitsa ku chinthu chakhumi.
Kuti mutsimikizire kupangidwa bwino ndi kukhazikitsa kwa mapaipi, ziyenera kutsimikiziridwa. Izi zimachitika poyerekezera deta yojambula ndi deta yomwe imayesedwa pambuyo poyikidwa. Miyezo ya mpweya wa m'chipinda cha munthu m'zipinda zokhala ndi mpweya komanso kusintha kwa kutentha kwa ma ducts ndi miyeso iwiri ikuluikulu yomwe iyenera kusonkhanitsidwa. Agwiritseni ntchito kuti adziwe kuchuluka kwa ma BTU operekedwa ku nyumba ndikuwonetsetsa kuti kapangidwe kake kakwaniritsidwa.
Izi zitha kubwereranso kwa inu ngati mudalira njira yanu yopangira, poganiza kuti dongosololi likuchita momwe mukuyembekezera. Kutayika kwa kutentha / kupindula, kusankha zipangizo ndi kuwerengera kwa mapaipi sikuli ndi cholinga chotsimikizira kugwira ntchito - osati kunja. M'malo mwake, agwiritseni ntchito ngati milingo yoyezera magawo omwe adayikidwa.
Popanda kukonza, magwiridwe antchito a mapaipi anu amawonongeka pakapita nthawi. Ganizirani momwe ma ducts a mpweya a sofa kapena mawaya otsamira m'mbali amawonongera mpweya - mumazindikira bwanji?
Yambani kuyeza ndikujambulitsa kupanikizika kwanu pa kuyimba kulikonse. Pambuyo potsimikizira kuti mapaipi akugwira ntchito bwino, sitepe iyi yobwerezabwereza imakupatsani mwayi wowunika kusintha kulikonse. Izi zimakupatsani mwayi wolumikizana ndi ma ductwork ndikukupatsani kumvetsetsa bwino zazinthu zomwe zikuwononga magwiridwe antchito anu.
Mawonedwe apamwambawa a momwe zinthu 10 izi zimagwirira ntchito limodzi kuti zitsimikizire momwe ma duct system amagwirira ntchito akuyenera kukupangitsani kuganiza.
Dzifunseni moona mtima: ndi zinthu ziti zomwe mukuziganizira, ndipo muyenera kuziganizira?
Gwirani ntchito pazinthu zapaipi izi imodzi ndi imodzi ndipo pang'onopang'ono mudzakhala wogulitsa pang'ono. Aphatikizepo pakukhazikitsa kwanu ndipo mupeza zotsatira zomwe palibe wina aliyense angafanane nazo.
