Chipinda chowongolera mpweya (AHU) ndiye chowongolera mpweya chachikulu kwambiri, chomwe chimakhalapo, ndipo chimakhala padenga kapena khoma lanyumba. Izi ndi kuphatikiza kwa zida zingapo zotsekedwa ngati chipika chowoneka ngati bokosi, chomwe chimagwiritsidwa ntchito kuyeretsa, zoziziritsira mpweya, kapena kutsitsimutsa mpweya mnyumba. Mwachidule, magawo oyendetsa mpweya amawongolera (kutentha & chinyezi) momwe mpweya umatenthera, komanso ukhondo wa kusefedwa kwake, ndipo amatero pogawa mpweya kudzera m'mipata yomwe imafikira chipinda chilichonse chanyumba yanu. Mosiyana ndi ma air conditioners wamba, ahu hvac amamangidwa kuti agwirizane ndi nyumba imodzi, ndikuwonjezera zosefera zamkati, zoziziritsa kukhosi, ndi zida zina zowongolera mulingo wa mpweya ndi kukhazikika mkati.

Ntchito zazikulu za AHU

Makina a Heating, Ventilation, and Air Conditioning (Commerical Industrial HVAC) ali pamtima pamainjini amakono, omwe amayenera kugwira ntchito pogwiritsa ntchito mpweya wabwino komanso mpweya wabwino m'nyumba zazikulu. Ahu mu hvac nthawi zambiri amayikidwa padenga kapena pakhoma lakunja ndikugawa mpweya wokhala ndi mpweya kudzera m'mipata kupita kuzipinda zosiyanasiyana. Makinawa amapangidwa kuti akwaniritse zofunikira zanyumba momwe amayenera kuzizirira, kutenthetsa, kapena mpweya wabwino.

Magawo oyendetsa mpweya wa Hvac ndi ofunikira paukhondo wa mpweya komanso kuwongolera kwa CO2 m'malo okhala ndi anthu ambiri monga malo ogulitsira, malo owonetserako zisudzo, ndi holo zamisonkhano. Amakoka mpweya wabwino ndikuthandizira kuchepetsa kuchuluka kwa mafani akuwombeza omwe amafunikira - ma feri awiri kuti apulumutse pamtengo wamagetsi ndikukwaniritsa zofunikira zoyendera mpweya. Malo ovuta, monga zipinda zoyeretsera, malo ochitirako opaleshoni, ndi zina zotero. Sizifuna kuwongolera kutentha kokha, komanso ukhondo wofunikira womwe umathandizidwa ndi magawo odzipereka owongolera mpweya wabwino. Komanso, makina ogwiritsira ntchito mpweya wosaphulika amateteza kuphulika kwa gasi kumalo ogwiritsira ntchito mpweya woyaka.

Kodi AHU imakhala ndi chiyani?

Ⅰ. Kutengera Mpweya: Chigawo chowongolera mpweya chimalowetsa mpweya wakunja, kusefa, kuwongolera, ndikuwuzungulira mnyumbamo kapena kubwereza mpweya wamkati ngati kuli koyenera.

Ⅱ. Zosefera za Air: Izi zitha kukhala zosefera zamakina zomwe zimatha kuchotsa zinthu zosiyanasiyana zowononga mpweya - fumbi, mungu, ngakhale mabakiteriya. M'makhitchini kapena malo ogwirira ntchito, zosefera zapadera zimatha kuthana ndi zoopsa zinazake, kulimbikitsa mpweya wabwino komanso kupewa kuchulukana kwazinthu m'dongosolo.

Ⅲ. Chokupizira: Gawo lofunika kwambiri la hvac mpweya wonyamula mpweya, zomwe zimatulutsa mpweya mu ductwork. Kusankhidwa kwa mafani malinga ndi mtundu wake kuphatikiza mafani opindika kutsogolo, okhota kumbuyo ndi a airfoil molingana ndi kupanikizika kosasunthika komanso zosowa zakuyenda kwa mpweya.

Ⅳ. Heat Exchanger: Chosinthira kutentha chimagwiritsidwa ntchito kulola kuyanjana kwa kutentha pakati pa mpweya ndi zoziziritsa kukhosi, ndikuthandizira kubweretsa mpweya ku kutentha komwe kumafunikira.

Ⅴ. Kozira Kuziziritsa: Mazenera oziziritsa amachepetsa kutentha kwa mpweya womwe ukudutsa pogwiritsa ntchito madontho amadzi omwe amatengedwa mu tray ya condensate.

Ⅵ. ERS: The Energy Recovery System (ERS) imathandizanso kuwongolera mphamvu zamagetsi mwa kusamutsa mphamvu yotentha pakati pa mpweya wotengedwa ndi mpweya wakunja, kuchepetsa kutentha kwina kapena kuziziritsa kowonjezera.

Ⅶ. Zinthu Zotenthetsera: Kupereka malamulo owonjezera a kutentha, zida zowotcha, kuphatikiza zotenthetsera zamagetsi kapena zosinthira kutentha, zitha kuphatikizidwa mu AHU.

Ⅷ. Humidifier(s)/De-Humidifier(s): Izi ndi zida zomwe zimayang'anira chinyezi chamlengalenga kuti chikhale choyenera m'nyumba.

Ⅸ. Gawo Losakaniza: Izi zimapanga kusakaniza koyenera kwa mpweya wamkati ndi kunja kwa mpweya, kotero kuti mpweya wotumizidwa kuti ukhale wokhazikika uli pa kutentha koyenera ndi khalidwe pamene ukugwiritsa ntchito mphamvu zochepa momwe zingathere.

Ⅹ. Causative: Silencers: Amachepetsa phokoso kuti chilengedwe chikhale chosangalatsa monga Phokoso limapangidwa panthawi ya mafani ndi zigawo zina.

Kugwiritsa ntchito mphamvu kwa AHUs

Kugwiritsa ntchito mphamvu zamagetsi (kuyambira 2016, chofunikira pansi pa European Ecodesign Regulation 1235/2014) ndichinthu chofunikira kwambiri pagawo loyendetsa mpweya (AHU). Imatero ndi mayunitsi obwezeretsa kutentha omwe amasakaniza mpweya wamkati ndi wakunja, kubweretsa kusiyana kwa kutentha pamodzi, komwe kumapulumutsa mphamvu pakuwongolera mpweya. Mafani ali ndi machitidwe osinthika omwe amawapatsa kuthekera kosinthira kumayendedwe a mpweya ngati pakufunika, kupangitsa kuti gawo la hvac mpweya likhale logwira ntchito bwino komanso lopanda mphamvu zambiri.
