Pakadali pano, pali mitundu iwiri ya makina oziziritsira mpweya ndi otenthetsera magalimoto amagetsi okha:Zotenthetsera za PTC thermistorndi makina opopera kutentha. Mfundo zogwirira ntchito za mitundu yosiyanasiyana ya makina opopera kutentha zimasiyana kwambiri.
PTC yomwe imagwiritsidwa ntchito m'magalimoto amagetsi okhaokha ndi semiconductor thermistor. Chifukwa cha mawonekedwe osavuta, mtengo wotsika, komanso kutentha mwachangu, ma heater a PTC akhala akugwiritsidwa ntchito kwambiri m'magalimoto amagetsi okhaokha (makamaka mitundu yotsika). Zachidziwikire, pali zosiyana. NIO ES8, yomwe ili pakati mpaka pamwamba, imagwiritsabe ntchitoChotenthetsera mpweya cha PTCndipo ili ndi zotenthetsera ziwiri za PTC.
Ntchito ya pampu yotenthetsera ndi kusamutsa mphamvu ya kutentha kuchokera ku gwero lotentha lotsika kwambiri kupita ku gwero lotentha lotentha kwambiri. Mfundo yake yogwirira ntchito ndi yofanana ndi ya makina oziziritsira mpweya, kupatula kuti njira yosamutsira kutentha ndi yosiyana. Choziziritsira mpweya chikazizira, chimasamutsa kutentha kuchokera m'nyumba kupita panja, pomwe makina otenthetsera mpweya amasamutsa kutentha kuchokera kunja kwa galimoto kupita mkati mwa galimoto. Makina otenthetsera mpweya nthawi zambiri amaphatikizidwa ndi makina oziziritsira mpweya ndi firiji, ndipo njira yosamutsira kutentha imayendetsedwa kudzera mu valavu. Kuphatikiza apo, potenthetsera, kutentha kwa batire yamagetsi kungagwiritsidwe ntchito bwino. Pachifukwa ichi, kumafanana ndi makina otenthetsera a galimoto yachikhalidwe. Chifukwa chake, poyerekeza ndi chotenthetsera cha PTC, mphamvu ya kutentha ya makina otenthetsera mpweya ndi yayikulu, kugwiritsa ntchito mphamvu kumakhala kotsika, ndipo mphamvu pa liwiro loyenda ndi yochepa. Koma zovuta zake ndizodziwikiratu: kapangidwe kovuta, mtengo wokwera, liwiro lotenthetsera pang'onopang'ono, makamaka kutentha pang'ono, mphamvu ya kutentha ndi yotsika.
Kutengera zomwe zili pamwambapa, m'magalimoto ena amagetsi apakatikati mpaka apamwamba, kuti muwonetsetse kutentha m'kabati, njira yosakanizidwa ya pampu yotenthetsera +Kutentha kwa PTC koziziritsirar imagwiritsidwa ntchito nthawi zambiri. Pa gawo loyamba, kutentha kwa makina oziziritsira batire yamagetsi kukakhala kochepa, chotenthetsera cha PTC chimayatsidwa kaye, ndipo makina otenthetsera a pampu yotenthetsera amayamba kutentha kwa choziziritsira kukwera.
Cholinga choyambirira cha magalimoto amagetsi ophatikizana ndi pulagi-in ndikutha kugwiritsa ntchito popanda mafuta. Ulendo watsiku ndi tsiku umadalirabe magetsi enieni. Sizingayendetse, zitha kugwiritsa ntchito PTC, heat pump kapena plus pulse heating. Pakadali pano, magalimoto ophatikizana monga DM-i amagwiritsa ntchito PTC kwambiri potenthetsera. Mfundo yotenthetsera ndi yosavuta, yomwe ndi "magetsi otenthetsera".
