Thempweya ozizirandi chipangizo chomwe chimagwiritsa ntchito mpweya wozungulira ngati sing'anga yozizira kuziziritsa kapena kutsitsa kutentha kwambiri kwamadzi mu chubu posesa kunja kwa chubu chotsekedwa, chomwe chimatchedwa "air cooler", chomwe chimadziwikanso kuti "air-cooled heat exchanger. ”, “mtundu woziziritsa mpweya” (Madzi kupita ku mpweya) chosinthira kutentha”.
Ngati kutentha komaliza kwa sing'anga iliyonse yozizirira kumasiyana ndi kutentha kwapafupi ndi 15 ℃, choziziritsira mpweya chingagwiritsidwe ntchito.Mpweya sutha komanso umapezeka paliponse.Mpweya umagwiritsidwa ntchito m'malo mwa madzi opangira chikhalidwe monga choziziritsira, chomwe sichimangothetsa vuto lamadzi.Akusowa, ndipo kuipitsidwa kwa madzi kwathetsedwa.Zoziziritsa mpweya zakhala zikugwiritsidwa ntchito kwambiri muzamankhwala, petrochemical ndi zina.Makamaka,Kupanga bwino kwa mitundu yosiyanasiyana ya machubu opangidwa ndi zingwe kwathandizira kwambiri kutengera kutentha kwa zoziziritsira mpweya ndipo pang'onopang'ono kumachepetsa kuchuluka kwake.
Zoziziritsa mpweya zimatha kugawidwa m'njira zosiyanasiyana chifukwa cha mapangidwe awo osiyanasiyana, mawonekedwe oyikapo, kuziziritsa ndi njira zopumira mpweya.
a.Kutengera ndi mitundu yosiyanasiyana ya machubu ndi mawonekedwe oyika, imagawidwa kukhala choziziritsa mpweya chopingasa komanso chozizira chapamwamba.Yoyambayo ndi yoyenera kuziziritsa, ndipo yotsirizirayi ndi yoyenera kuziziritsa kosiyanasiyana kwa condensation.
b.Malinga ndi njira zosiyanasiyana zoziziritsira, zimagawidwa kukhala zoziziritsira mpweya wouma komanso zoziziritsira mpweya wonyowa.Woyambayo amazizidwa ndi wowuzira mosalekeza;yotsirizirayi ndi njira yopopera madzi kapena atomization kuti apititse patsogolo kutentha.Chotsatiracho chimakhala ndi kuzizira kwambiri kuposa kale, koma sichigwiritsidwa ntchito
kwambiri chifukwa ndikosavuta kuchititsa dzimbiri kwa chubu mtolo ndi kukhudza moyo wa mpweya ozizira.
c.Malinga ndi njira zosiyanasiyana zopangira mpweya, zimagawidwa kukhala mpweya wokakamiza (ndiko kuti, mpweya) wozizirira komanso woziziritsira mpweya wochititsa kuti mpweya wabwino.Wokupiza wakale amayikidwa m'munsi mwa chubu mtolo ndipo amagwiritsa ntchito axial fan kutumiza mpweya ku mtolo wa chubu;fan yomaliza imayikidwa kumtunda kwa chubu mtolo, ndipo mpweya umayenda kuchokera pamwamba mpaka pansi.Chotsatiracho chimadya mphamvu zambiri ndipo chimawononga ndalama zambiri kuposa chakale, ndipo kugwiritsa ntchito kwake sikuli kofala monga kale.
Chozizira chapamwamba chophatikizika chapamwamba ndi mtundu watsopano wa zida zosinthira kuzizira zomwe zimaphatikiza kutentha kobisika ndi njira zosinthira kutentha, ndikuwongolera kuphatikiza kwa kuzizira kwa evaporative (condensation) ndi kuziziritsa kwa mpweya wonyowa.Poyerekeza ndi zoziziritsira mpweya, zoziziritsa kukhosi zophatikizika zogwira ntchito kwambiri sizingokhala zotetezeka Zodalirika, zopulumutsa madzi, zopulumutsa mphamvu, zowononga chilengedwe komanso zimakhala zotsika mtengo pakugulitsa koyambirira ndikugwiritsa ntchito.
