Panthawi yopenta, mpweya wakunja umasefedwa kudzera mu fyuluta yoyamba ndikuperekedwa padenga ndi fani. Pambuyo kusefedwa kachiwiri ndi kuyeretsedwa ndi fyuluta yapamwamba, imalowa m'nyumba. Mpweya mkati mwa kanyumbako umayenda pansi pa liwiro la Greater kuposa kapena wofanana ndi 0.3 m / s, kuteteza utoto wa nkhungu particles kuti ukhale mlengalenga ndi kuwalola kudutsa mwachindunji pansi fyuluta asanatope panja panja. Kuyenda kosalekeza kumeneku kumatsimikizira kuti ukhondo wa mpweya mkati mwa kanyumbako umafika pa 98% panthawi yopaka utoto, ndipo mpweya womwe umaperekedwa umakhala ndi mphamvu inayake yoletsa fumbi kuti lisalowe m'malo opopera ndikuyipitsa malo opangira ntchito, motero kumapangitsa kuti utoto ukhale wabwino.
Panthawi yophika, damper imasinthidwa ku malo ophika, ndipo mpweya wotentha umazungulira, kukweza kutentha mkati mwa chophika chophika mpaka kutentha komwe kunakonzedweratu (zosachepera kapena zofanana ndi 80 digiri). Zimakupiza poyamba zimasefa mpweya wabwino wakunja, womwe umasinthasintha kutentha ndi chotenthetsera chisanaperekedwe ku chipinda cha mpweya pamwamba pa chophikira. Pambuyo pa kusefera kwachiwiri ndi kuyeretsedwa, mpweya wotentha, kupyolera mu kayendedwe ka mkati mwa damper, nthawi zambiri umatenthedwa ndikugwiritsidwanso ntchito, kupatulapo mpweya wochepa, womwe umapangitsa kutentha mkati mwa chophika chophika pang'onopang'ono. Kutentha kukafika pa kutentha komwe kumayikidwa, chowotchacho chimangoyima; pamene kutentha kumatsikira pa kutentha kokhazikitsidwa, chowotcha ndi chowotcha chimayatsanso kuti chikhalebe kutentha kosalekeza mkati mwa kanyumba ka penti. Pomaliza, nthawi yophika utoto ikafika nthawi yoikika, malo opangira utoto amangotseka, ndipo ntchito yophika utoto yatha.
