Kuti kutentha kusamutsidwe pogwiritsa ntchito madzi ngati njira yolumikizirana, ndikofunikira kukhazikitsa kulumikizana kotumizira kutentha pakati pa gawoli ndi njira yolumikizira madzi, monga jekete la madzi, kuti kutenthetse ndi kuziziritsa mosalunjika mu mawonekedwe a convection ndi kutentha. Njira yotumizira kutentha ikhoza kukhala madzi, ethylene glycol kapena Refrigerant. Palinso kusamutsa kutentha mwachindunji mwa kumiza chidutswa cha ndodo mu madzi a dielectric, koma njira zotetezera ziyenera kutengedwa kuti tipewe kufupika kwa mpweya. (Chotenthetsera Choziziritsira cha PTC)
Kuziziritsa kwa madzi kosakhazikika nthawi zambiri kumagwiritsa ntchito kusinthana kutentha kwa mpweya komwe kumakhala ndi madzi kenako kumalowetsa zikwakwa mu batire kuti zisinthena kutentha kwina, pomwe kuziziritsa kwamphamvu kumagwiritsa ntchito zosinthira kutentha kwapakati pa injini zoziziritsira-madzi, kapena kutentha kwamagetsi/mafuta otenthetsera kuti ziziziritse koyamba. Kutenthetsera, kuziziritsa koyamba ndi mpweya/mpweya woziziritsa refrigerant-madzi.
Pa makina oyendetsera kutentha omwe amagwiritsa ntchito mpweya ndi madzi ngati cholumikizira, kapangidwe kake ndi kakakulu kwambiri komanso kovuta chifukwa cha kufunikira kwa mafani, mapampu amadzi, zosinthira kutentha, zotenthetsera, mapaipi ndi zina zowonjezera, ndipo imagwiritsanso ntchito mphamvu ya batri ndikuchepetsa mphamvu ya batri.Chotenthetsera Mpweya cha PTC)
Dongosolo loziziritsira batire loziziritsidwa ndi madzi limagwiritsa ntchito choziziritsira (50% madzi / 50% ethylene glycol) kuti litumize kutentha kwa batire ku dongosolo loziziritsira mpweya kudzera mu choziziritsira batire, kenako kupita kumalo ozungulira kudzera mu choziziritsira. Kutentha kwa madzi olowera batire kumaziziritsidwa ndi batire. N'zosavuta kufika kutentha kotsika pambuyo posinthana kutentha, ndipo batire ikhoza kusinthidwa kuti igwire ntchito pa kutentha koyenera; mfundo ya dongosololi ikuwonetsedwa pachithunzichi. Zigawo zazikulu za dongosolo loziziritsira ndi izi: choziziritsira, compressor yamagetsi, evaporator, valavu yowonjezera yokhala ndi valavu yotseka, choziziritsira batire (valavu yowonjezera yokhala ndi valavu yotseka) ndi mapaipi oziziritsira mpweya, ndi zina zotero; dera loziziritsira madzi limaphatikizapo:pampu yamadzi yamagetsi, batire (kuphatikizapo mbale zoziziritsira), zoziziritsira mabatire, mapaipi amadzi, matanki owonjezera ndi zina zowonjezera.
M'zaka zaposachedwa, njira zoyendetsera kutentha kwa mabatire zomwe zimaziziritsidwa ndi zinthu zosintha magawo (PCM) zawonekera kunja ndi kunyumba, zomwe zikusonyeza kuti zinthu zikuyenda bwino. Mfundo yogwiritsira ntchito PCM poziziritsa mabatire ndi iyi: pamene batire ikutulutsidwa ndi mphamvu yayikulu, PCM imayamwa kutentha komwe kumatulutsidwa ndi batire, ndipo imasinthasintha gawo lokha, kotero kuti kutentha kwa batire kumatsika mofulumira.
Munjira imeneyi, makinawa amasunga kutentha mu PCM mu mawonekedwe a kutentha kosintha gawo. Batire ikayamba kuchajidwa, makamaka nyengo yozizira (ndiko kuti, kutentha kwa mlengalenga kumakhala kotsika kwambiri kuposa kutentha kwa kusintha gawo PCT), PCM imatulutsa kutentha kumalo ozungulira.
Kugwiritsa ntchito zipangizo zosintha magawo m'machitidwe oyang'anira kutentha kwa batri kuli ndi ubwino woti sikufuna kusuntha ziwalo ndikugwiritsa ntchito mphamvu yowonjezera kuchokera ku batri. Zipangizo zosintha magawo zomwe zimakhala ndi kutentha kobisika komanso kutentha kosasunthika, zomwe zimagwiritsidwa ntchito mu dongosolo loyang'anira kutentha kwa batri zimatha kuyamwa bwino kutentha komwe kumatulutsidwa panthawi yochaja ndi kutulutsa, kuchepetsa kukwera kwa kutentha kwa batri, ndikuwonetsetsa kuti batri ikugwira ntchito kutentha kwabwinobwino. Zitha kusunga magwiridwe antchito a batri asanayambe komanso pambuyo pa kuzungulira kwamphamvu kwamagetsi. Kuwonjezera zinthu zomwe zimakhala ndi kutentha kwakukulu ku parafini kuti apange PCM yophatikizika kumathandiza kukonza magwiridwe antchito onse a zinthuzo.
Kuchokera pa mitundu itatu yomwe ili pamwambapa ya njira zoyendetsera kutentha, kayendetsedwe ka kutentha kosungira kutentha kosintha gawo kali ndi ubwino wapadera, ndipo ndikoyenera kufufuza kwina ndi chitukuko cha mafakitale ndikugwiritsa ntchito.
Kuphatikiza apo, poganizira maulalo awiri a kapangidwe ka batri ndi chitukuko cha makina oyendetsera kutentha, ziwirizi ziyenera kuphatikizidwa kuchokera kutalika kwanzeru ndikupangidwa mogwirizana, kuti batri lizitha kusintha bwino kugwiritsa ntchito ndi kupanga galimoto yonse, zomwe zingapulumutse mtengo wa galimoto yonse, komanso zitha kuchepetsa zovuta zogwiritsira ntchito ndi ndalama zoyendetsera, ndikupanga pulogalamu yogwiritsira ntchito nsanja, potero kufupikitsa kayendedwe ka kupanga magalimoto atsopano amphamvu ndikufulumizitsa kupita patsogolo kwa malonda a magalimoto atsopano osiyanasiyana amphamvu.
