1. Mfundo yoyendetsera galimoto yoyera yamagetsi yamagetsi ndi kusonkhanitsa chidziwitso kuchokera ku gawo lililonse la zipangizo zopangira mpweya kudzera mu VCU (electronic control unit), kupanga chizindikiro chowongolera, ndikuchitumiza ku air-conditioning. mabasi owongolera (control circuit) kudzera mu CAN, kuti wowongolera mpweya aziwongolera kuponderezana kwa mpweya.air conditioning system.
Kuthetsa mavuto ndi njira zothetsera ma air-conditioning a magalimoto oyera amagetsi
Makina owongolera mpweya sangayambike
Pavuto loti mpweya wotulutsa mpweya sutulutsa mpweya, kutengera zomwe zachitika, zimawonedwa makamaka kuti makina osinthira ma air conditioner ali mu defrost mode. Ngati mpweya wozizira suli wochepetsetsa, ogwira ntchito yokonza ayenera kuyang'ana liwiro loyang'anira resistor ndi chingwe chamagetsi, nthawi zambiri amagwiritsa ntchito multimeter kuyesa voteji. Ngati mizere yonse ili m'lingaliro, wowumayo amafunikira kuunikanso ndikusinthidwa. Ngati kulephera kwa air conditioner kumayamba chifukwa cha mphepo yochokera ku mpweya koma palibe mpweya wozizira womwe umatuluka, muyenera kufufuza kaye mphamvu ya batri ya galimoto yoyera yamagetsi kuti mudziwe ndi kukonza. Ngati kutentha kwa sensa kuli bwino, muyenera kuyang'ana payipi ndi kuthamanga kwa refrigerant.
Kuziziritsa kwa makina owongolera mpweya ndikovuta
Njira yodziwira kuti kuzizira kozizira ndi motere: Poyang'anira, onetsetsani kuti malo agalimoto amagetsi akusungidwa pakati pa 20-35 ° C, ikani mpweya wotulutsa mpweya wa air conditioner kuti uwonongeke, ndipo ogwira ntchito yosamalira akhazikitse chowombera. zida zapamwamba. Kenako, gwirizanitsani kuthamanga kwapamwamba ndi kutsika kwa choyimitsira mpweya kudzera mu geji yochuluka ya kuthamanga ndikuwona kuwerengera kwa pressure. Ngati kuchuluka kwa kuthamanga kwapamwamba ndi kutsika kuli kochepa kuposa momwe zimakhalira, zimasonyeza kuti palibe refrigerant yokwaniraair conditioning system. Ngati mtengowo ndi wotsika kwambiri, zikuwonetsa kuti pali kutayikira munjira yowongolera mpweya ndipo iyenera kupezeka. Ngati kuthamanga kwakukulu kuli koyenera koma kutsika kwapansi kumakhala kwakukulu kuposa 0.3MPa, ndipo kutentha kwa payipi yotsika kwambiri kumakhala kotsika kwambiri, kungayambitsidwe ndi vaporization yambiri ya firiji chifukwa cha kusintha kwakukulu kwa valve yowonjezera, kotero kusintha valavu yowonjezera ndiyokwanira.
Mpweya wozizira umakhala waphokoso
Pakugwedezeka kwa kompresa ndi phokoso, tiyenera kudziwa kaye ngati zimayamba chifukwa cha kulephera kwa chotsitsa champira kapena kumasulidwa kwa mabawuti okonzera kompresa. Ngati pad mphira si wolakwika pambuyo kuyendera, muyenera kufufuza kugwirizana kwa madera osiyanasiyana, monga magawo atatu kugwirizana dera pakati kompresa ndi wolamulira. Mwachitsanzo, pamenekompresa imapanga phokoso lopweteka, zikhoza kuweruzidwa kuti compressor yokha yawonongeka ndipo compressor iyenera kusinthidwa. Ngati chotenthetsera cha condensing chikupanga phokoso lalikulu, yang'anani kaye mphira wa rabara pomwe chowongolerera chimayikidwa. Ngati vutoli likupitilirabe pambuyo pa kusinthidwa, likhoza kuyambitsidwa ndi kuvala kwa fani yamoto ya condensing ndipo fani yoyatsira iyenera kusinthidwa.
Kuphatikiza pa zolakwika zomwe zili pamwambazi, makina oziziritsa mpweya alinso ndi zovuta kuzizira kwapakatikati. Pavutoli, ndikofunikira kuyang'ana ngati kutentha kwa kompresa kumaposa mtengo wadongosolo lonse lagalimoto. Mwachitsanzo, magalimoto abwino amagetsi amayika kutentha kwa chitetezo cha kompresa ku 85 ° C. Ngati mtengowo udutsa mtengowu, dongosololi lizitulutsa zokhalamulo loletsa kompresa. Cholakwika ichi makamaka chimayamba chifukwa cha kulephera kwa firiji ya compressor, zomwe zimapangitsa kuti kutentha kwa compressor kukhale kokwera kwambiri, ndipo chowongolera chowongolera chiyenera kusinthidwa. Mukasintha chowongolera, perekani mafuta a silicone otenthetsera mofanana pamalo olumikizirana kuti muchepetse kutseka kwa kompresa chifukwa cha kutentha kwambiri.
