Chipinda chowongolera mpweya (AHU) ndi chipinda chachikulu kwambiri chowongolera mpweya chomwe chilipo, ndipo nthawi zambiri chimakhala padenga kapena pakhoma la nyumba. Izi ndi kuphatikiza kwa zida zingapo zotsekedwa ngati bokosi looneka ngati bokosi, zomwe zimagwiritsidwa ntchito poyeretsa, kuziziritsa mpweya, kapena kutsitsimutsa mpweya m'nyumba. Mwachidule, zipinda zowongolera mpweya zimawongolera (kutentha ndi chinyezi) kutentha kwa mpweya, komanso kuyera kwa kusefedwa kwake, ndipo amachita izi pogawa mpweya kudzera m'mitsempha yomwe imafikira chipinda chilichonse m'nyumba mwanu. Mosiyana ndi zoziziritsira mpweya wamba, ahu hvac imapangidwa kuti igwirizane ndi nyumba iliyonse, kuwonjezera zosefera zamkati, zonyowetsa chinyezi, ndi zida zina kuti ziwongolere muyezo wa mpweya ndi bata mkati.

Ntchito zazikulu za AHU

Makina otenthetsera, Mpweya, ndi Mpweya Woziziritsa (Commerical Industrial HVAC) ndi ofunika kwambiri pa injini zamakono, zomwe ziyenera kugwira ntchito pogwiritsa ntchito mpweya wabwino komanso mpweya wabwino m'nyumba zazikulu. Ahu mu hvac nthawi zambiri amayikidwa padenga kapena pakhoma lakunja ndipo amagawa mpweya woziziritsa kudzera m'mitsempha kupita kuzipinda zosiyanasiyana. Makina awa amapangidwa kuti agwirizane ndi zofunikira za nyumbayo pomwe ayenera kuziziritsa, kutenthetsa, kapena kupumitsa mpweya.

Magawo ogwiritsira ntchito mpweya wa Hvac ndi ofunikira kwambiri paukhondo wa mpweya ndi kuwongolera mulingo wa CO2 m'malo odzaza magalimoto monga m'masitolo akuluakulu, m'malo ochitira zisudzo, ndi m'maholo amisonkhano. Amakoka mpweya wabwino ndipo amathandiza kuchepetsa chiwerengero cha mafani ofukula mpweya omwe amafunikira - nthawi imodzi kuti achepetse ndalama zamagetsi ndikukwaniritsa zofunikira pakutsata khalidwe la mpweya. Malo ofunikira, monga zipinda zoyera, malo ochitira zisudzo, ndi zina zotero, samangofuna kuwongolera kutentha kokha, komanso ukhondo wofunikira womwe nthawi zambiri umathandizidwa ndi mayunitsi apadera ogwiritsira ntchito mpweya watsopano. Komanso, makina ogwiritsira ntchito mpweya osaphulika amateteza ku kuphulika kwa mpweya m'malo ogwiritsira ntchito mpweya woyaka.

Kodi AHU imapangidwa ndi chiyani?

Ⅰ. Mpweya Wolowa: chipangizo choyendetsera mpweya chomwe chimagwiritsidwa ntchito panyumba chimatenga mpweya wakunja, kusefa, kukonza mpweya, ndikuwuzungulira mnyumbamo kapena kubwerezabwereza mpweya wamkati ngati kuli koyenera.

Ⅱ. Zosefera za Mpweya: Izi zitha kukhala zosefera zamakina zomwe zimatha kutulutsa zinthu zosiyanasiyana zoipitsa mpweya — fumbi, mungu, komanso mabakiteriya. M'makhitchini kapena m'ma workshop, zosefera zapadera zingathandize kuthana ndi zoopsa zinazake, kulimbikitsa mpweya woyera komanso kupewa kusonkhanitsa zinthu m'dongosolo.

Ⅲ. Fani: Gawo lofunika kwambiri la chipangizo choyendetsera mpweya cha hvac ndi fan, yomwe imatulutsa mpweya mu ductwork. Kusankha fan malinga ndi mtundu wake kuphatikizapo mafani okhota kutsogolo, okhota kumbuyo ndi mafani a airfoil malinga ndi kupanikizika kosasinthasintha ndi zosowa za mpweya.

Ⅳ. Chosinthira kutentha: Chosinthira kutentha chimagwiritsidwa ntchito kulola kutentha pakati pa mpweya ndi choziziritsira, komanso kuthandiza kukweza mpweya kufika kutentha kofunikira.

Ⅴ. Chozira Choziziritsira: Chozira choziziritsira chimatsitsa kutentha kwa mpweya komwe kumadutsa pogwiritsa ntchito madontho amadzi omwe amasonkhanitsidwa mu thireyi yoziziritsira.

Ⅵ. ERS: Dongosolo Lobwezeretsa Mphamvu (ERS) limathandizanso kukonza mphamvu mwa kusamutsa mphamvu yotentha pakati pa mpweya wotulutsidwa ndi mpweya wakunja, kuchepetsa kufunikira kowonjezera kwa kutentha kapena kuzizira.

Ⅶ. Zinthu Zotenthetsera: Kuti zipereke malamulo owonjezera kutentha, zinthu zotenthetsera, kuphatikizapo zotenthetsera zamagetsi kapena zosinthira kutentha, zitha kuphatikizidwa mu AHU.

Ⅷ. Chotenthetsera/Chosanyowetsa: Izi ndi zida zomwe zimawongolera chinyezi mumlengalenga kuti zikhale bwino m'nyumba.

Ⅸ. Gawo Losakaniza: Izi zimapangitsa kuti mpweya wamkati ndi wakunja ukhale wogwirizana, kotero kuti mpweya wotumizidwa kuti ukakonzedwe ukhale pa kutentha koyenera komanso wabwino pamene ukugwiritsa ntchito mphamvu zochepa momwe zingathere.

Ⅹ. Choyambitsa: Zoletsa phokoso: Zimachepetsa phokoso kuti chilengedwe chikhale chosangalatsa pamene phokoso limapangidwa panthawi yogwira ntchito ya mafani ndi zida zina.

Kugwiritsa ntchito bwino mphamvu kwa AHUs

Kugwiritsa ntchito bwino mphamvu (kuyambira mu 2016, lamulo loperekedwa ndi European Ecodesign Regulation 1235/2014) ndi chinthu chofunikira kwambiri pa chipangizo chowongolera mpweya (AHU). Chimachita izi ndi zida zowongolera kutentha zomwe zimasakaniza mpweya wamkati ndi wakunja, zomwe zimapangitsa kuti kutentha kukhale kofanana, zomwe zimasunga mphamvu ya mpweya woziziritsa. Mafani ali ndi mphamvu zowongolera zomwe zimawapatsa mphamvu yosinthira kufunikira kwa mpweya momwe akufunira, zomwe zimathandiza chipangizo chowongolera mpweya cha hvac kukhala chogwira ntchito bwino komanso chosowa mphamvu zambiri.
