Mpweya wozizira wa evaporative ndi kuziziritsa msonkhanowo kudzera mu nthunzi wa madzi.Zotsatirazi ndi gawo lachidule la mfundo zake zogwirira ntchito:
1. Kupereka madzi: mpweya wozizira wa evaporative nthawi zambiri umakhala ndi thanki yamadzi kapena chitoliro cha madzi, ndipo madzi amaperekedwa ku dongosolo kudzera pa mpope.
2. Katani yonyowa kapena sing'anga yotulutsa mpweya: Madzi amatumizidwa kunja kwa nsalu yonyowa kapena sing'anga ina yotulutsa mpweya.Makatani onyowa nthawi zambiri amapangidwa ndi mayamwidwe amphamvu amadzi, monga pepala la zisa kapena fiberboard.
3. Kugwira ntchito kwa fani: Fani imayamba, imayamwa mpweya wakunja m'mbali mwa sing'anga yotulutsa mpweya.
4. Mpweya wonyowa: Pamene mpweya wakunja umakhudzana ndi madzi pamwamba pa nsalu yonyowa kupyolera mu nsalu yonyowa, mamolekyu amadzi amasintha kuchokera kumadzi kupita ku mpweya, kutengera kutentha, ndi kuchepetsa kutentha kwa mpweya.

5. Kutulutsa mpweya wonyowa: Mpweya wonyowa umatulutsidwa kuchokera mbali ina kuti ulowe mu msonkhano kuti ukwaniritse mpweya wabwino ndi kuzizira.
Pochita izi, mpweya wotentha umatulutsa madzi kudzera mu kukhudzana ndi nsalu yonyowa, yomwe imazizira mpweya, ndipo nthawi yomweyo, chinyezi chidzawonjezeka.Njirayi ndi yoyenera ku malo owuma, chifukwa m'malo onyowa, kuthamanga kwa madzi kumayenda pang'onopang'ono, ndipo kuzizira kumatha kufooka.
Ubwino wa kutulutsa mpweya wabwino ndi kuziziritsa kwa msonkhano uli mu mfundo yake yosavuta yogwirira ntchito, kugwiritsa ntchito mphamvu zochepa, kutsika mtengo wokonza, ndi zofunika kuzizira zoyenera pamitundu ina.Komabe, ziyenera kudziwidwa kuti kuzizira kwake kungakhudzidwe ndi chinyezi cha chilengedwe ndi kutentha.
