Kutuluka kwa nthunzi ndi njira yeniyeni yosinthira madzi kukhala mpweya. Kawirikawiri, evaporator ndi chinthu chomwe chimasintha chinthu chamadzimadzi kukhala mpweya. Pali ma evaporator ambiri mumakampani, ndipo evaporator yomwe imagwiritsidwa ntchito mufiriji ndi imodzi mwa izo. Evaporator ndi gawo lofunika kwambiri pazigawo zinayi zazikulu za firiji. Madzi osungunuka otentha kwambiri amadutsa mu evaporator kuti asinthane kutentha ndi mpweya wakunja, amatuluka nthunzi ndikuyamwa kutentha, ndikukwaniritsa zotsatira za firiji. Evaporator imapangidwa makamaka ndi chipinda chotenthetsera ndi chipinda chotenthetsera. Chipinda chotenthetsera chimapatsa madziwo kutentha kofunikira kuti atulutse nthunzi, ndipo chimalimbikitsa madziwo kuwira ndi kusungunuka nthunzi; chipinda chotenthetsera chimalekanitsa kwathunthu magawo awiri a gasi ndi madzi.
Nthunzi yomwe imapangidwa mu chipinda chotenthetsera imakhala ndi thovu lamadzimadzi lochuluka. Pambuyo pofika mu chipinda chotenthetsera ndi malo akulu, madzi awa amalekanitsidwa ndi nthunziyo podzipanga okha kapena kuchita kwa chotenthetsera. Nthawi zambiri chotenthetsera chimakhala pamwamba pa chipinda chotenthetsera.
Evaporator imagawidwa m'mitundu itatu malinga ndi kuthamanga kwa ntchito: kuthamanga kwabwinobwino, kupanikizika ndi kumasuka. Malinga ndi kayendedwe ka yankho mu evaporator, likhoza kugawidwa m'magulu awa: ① mtundu wa kuyendayenda. Yankho lowira limadutsa pamwamba pa kutentha kangapo m'chipinda chotenthetsera, monga mtundu wa chubu chozungulira chapakati, mtundu wa dengu lopachikika, mtundu wa kutentha kwakunja, mtundu wa Levin ndi mtundu wa kukakamizidwa kuyendayenda. ②Mtundu wa njira imodzi. Yankho lowira limadutsa pamwamba pa kutentha kamodzi m'chipinda chotenthetsera popanda kuyenda kozungulira, ndiko kuti, madzi okhuthala amatulutsidwa, monga mtundu wa filimu yokwera, mtundu wa filimu yogwa, mtundu wa filimu yosonkhezera ndi mtundu wa filimu ya centrifugal. ③ Mtundu wolumikizana mwachindunji. Chotenthetsera chimakhudzana mwachindunji ndi yankho losamutsa kutentha, monga evaporator yoyaka pansi pamadzi. Pakugwira ntchito kwa chipangizo chotenthetsera, nthunzi yambiri yotenthetsera imagwiritsidwa ntchito. Pofuna kusunga nthunzi yotenthetsera, chipangizo chotenthetsera chokhala ndi zotsatira zambiri komanso evaporator yobwezeretsanso nthunzi chingagwiritsidwe ntchito. Evaporators amagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, magetsi ndi magawo ena.
Mankhwala oletsa ululu opumira omwe amagwiritsidwa ntchito mu mankhwala, ndi amadzimadzi pa kutentha kwa chipinda. Mankhwala oletsa ululu amatha kupumira bwino madzi opumira omwe amatuluka mu mpweya, ndipo amatha kusintha bwino kuchuluka kwa mpweya wotuluka mu anesthesia. Kupumira kwa mankhwala oletsa ululu kumafuna kutentha, ndipo kutentha kozungulira vaporizer ndi chinthu chachikulu chomwe chimapangitsa kuti pakhale kuchuluka kwa mpweya wopumira wa mankhwala oletsa ululu. Makina amakono oletsa ululu amagwiritsa ntchito kwambiri ma evaporators ochepetsa kutentha, kutanthauza kuti, kutentha kapena mpweya watsopano ukasintha, kuchuluka kwa mpweya wopumira wa mankhwala oletsa ululu opumira kumatha kusungidwa nthawi zonse kudzera mu njira yodziyimira yokha, kuti zitsimikizire kuti mankhwala oletsa ululu opumira amachoka mu evaporator. Kuchuluka kwa mpweya wotuluka kumakhala kokhazikika. Chifukwa cha zinthu zosiyanasiyana zakuthupi monga kutentha ndi kuthamanga kwa mpweya wodzaza wa mankhwala oletsa ululu osiyanasiyana opumira, ma vaporizer ali ndi mawonekedwe apadera a mankhwala, monga ma enflurane vaporizer, isoflurane vaporizer, ndi zina zotero, zomwe sizingagwiritsidwe ntchito mofanana. Ma vaporizer a makina amakono oletsa ululu nthawi zambiri amayikidwa kunja kwa dera lopumira la anesthesia, ndipo amalumikizidwa ndi kayendedwe ka mpweya kosiyana. Mpweya wopumira wophwanyika umasakanizidwa ndi mpweya waukulu womwe umayenda usanapumedwe ndi wodwalayo.
