M'nyengo yotentha kapena yozizira, mpweya wa galimoto ndi wofunika kwambiri kwa ife okonda magalimoto, makamaka pamene mazenera achita chifunga kapena chisanu. Kuthekera kwa makina oziziritsira mpweya kuti achepetse komanso kusungunula mwachangu kumagwira ntchito yofunika kwambiri pakuyendetsa chitetezo. Kwa magalimoto amagetsi, omwe alibe injini yamafuta, alibe gwero la kutentha kwa kutentha, ndipo kompresa ilibe mphamvu yoyendetsera injini kuti ipereke kuziziritsa. Ndiye kodi magalimoto amagetsi abwino amapereka bwanji ntchito zoziziritsa mpweya komanso zotenthetsera? Tiyeni tifufuze.
01 Zigawo za Air Conditioning System Yozizira
Zigawo za dongosolo loziziritsa mpweya ndi izi: kompresa yamagetsi, condenser, sensor sensor, valve yowonjezera yamagetsi, evaporator, mapaipi olimba a air conditioning, hoses, ndi control circuit.
Compressor:
Imatengera kutentha kwapang'onopang'ono komanso kutsika kwa mpweya mufiriji ndikuupanikiza kukhala mpweya wotentha kwambiri komanso wothamanga kwambiri wamadzi mufiriji. Panthawi yoponderezedwa, chikhalidwe cha refrigerant sichisintha, koma kutentha ndi kupanikizika kumawonjezeka, kupanga mpweya wotentha kwambiri.
Condenser:
Condenser imagwiritsa ntchito fani yodzipatulira yoziziritsa kuti iwononge kutentha kwa kutentha kwapamwamba komanso kupanikizika kwambiri kwa mpweya wozungulira, kuziziritsa mufiriji. Pochita izi, refrigerant imasintha kuchokera ku mpweya kupita ku madzi, ndipo imakhala yotentha kwambiri komanso yothamanga kwambiri.
Vavu Yokulitsa:
Refrigerant yotentha kwambiri komanso yothamanga kwambiri imadutsa mu valve yowonjezera kuti igwedezeke ndi kuchepetsa kupanikizika musanalowe mu evaporator. Cholinga cha ndondomekoyi ndi kuziziritsa ndi kuchepetsa refrigerant ndikuyendetsa kayendetsedwe kake kuti azitha kuziziritsa. Pamene refrigerant imadutsa mu valve yowonjezera, imasintha kuchokera kumadzi otentha kwambiri, othamanga kwambiri mpaka kutentha kwapansi, kutsika kwamadzimadzi.
Evaporator:
Refrigerant yamadzi otsika, yotsika kwambiri yochokera ku valavu yowonjezera imatenga kutentha kwakukulu kuchokera kumlengalenga wozungulira mu evaporator. Panthawi imeneyi, firiji imasintha kuchoka ku madzi kupita ku mpweya wochepa, wochepa kwambiri. Mpweya umenewu umayamwidwa ndi kompresa kuti apanikizidwe kachiwiri.
Kuchokera pamalingaliro oziziritsa, makina otenthetsera mpweya wa magalimoto amagetsi ndi ofanana kwenikweni ndi magalimoto achikhalidwe oyendera mafuta. Kusiyanaku kumakhala panjira yoyendetsera makina owongolera mpweya. M'magalimoto amtundu wamafuta, compressor imayendetsedwa ndi lamba wa injini, pomwe m'magalimoto amagetsi, kompresa imayendetsedwa ndi magetsi kuti iyendetse injini, yomwe imagwiritsa ntchito compressor kudzera mu crankshaft.
02 Air Conditioning Heating System
Gwero lotenthetsera limapezeka makamaka kudzera mu PTC (Positive Temperature Coefficient). Magalimoto amagetsi oyera nthawi zambiri amakhala ndi mitundu iwiri: gawo la PTC lotenthetsera mpweya ndi gawo la PTC lotenthetsera madzi. PTC ndi mtundu wa semiconductor thermistor, ndipo chikhalidwe chake ndi chakuti kukana kwa zinthu za PTC kumawonjezeka pamene kutentha kumakwera. Pansi pa voteji nthawi zonse, chotenthetsera cha PTC chimatentha mofulumira pa kutentha kochepa, ndipo pamene kutentha kumakwera, kukana kumawonjezeka, kutsika kumachepa, ndipo mphamvu yogwiritsidwa ntchito ndi PTC imachepa, motero kusunga kutentha kosasintha.
Mapangidwe Amkati a Air Heating PTC Module:
Amakhala ndi chowongolera (kuphatikiza moduli yamagetsi otsika / okwera kwambiri), zolumikizira waya zazitali / zotsika kwambiri, filimu yotenthetsera ya PTC, pad ya silicone yotenthetsera, ndi chipolopolo chakunja, monga momwe tawonera pachithunzichi.
Kutentha kwa mpweya PTC module amatanthauza kuyika mwachindunji PTC pakatikati pa mpweya wotentha wa kanyumba. Mpweya wa kanyumba umayendetsedwa ndi chowombera ndikutenthedwa mwachindunji ndi chowotcha cha PTC. Kanema wotenthetsera wotenthetsera mkati mwa gawo la PTC yotenthetsera mpweya amayendetsedwa ndi voliyumu yayikulu ndipo imayendetsedwa ndi VCU (Vehicle Control Unit).
03 Kulamulira kwa Magetsi a Galimoto Yamagetsi ya Air Conditioning System
VCU yagalimoto yamagetsi imasonkhanitsa ma sign kuchokera ku A/C switch, A/C pressure switch, kutentha kwa evaporator, liwiro la mafani, ndi kutentha kozungulira. Pambuyo pokonza ndi kuwerengera, zimapanga zizindikiro zowongolera, zomwe zimaperekedwa kwa wowongolera mpweya kudzera pa basi ya CAN. Woyang'anira mpweya amawongolera kuyatsa / kutseka kwamagetsi apamwamba a kompresa ya air conditioning, monga momwe chithunzichi chikusonyezera.
Izi zikumaliza kuyambika kwakukulu kwa makina owongolera mpweya wa magalimoto amagetsi. Kodi mwapeza zothandiza? Tsatirani Yiyi New Energy Vehicles kuti mudziwe zambiri zamaluso zomwe zimagawidwa sabata iliyonse.
