Kodi mpweya wozizira wagalimoto umagwira ntchito bwanji?
Ku North America konse, nyengo imasintha chaka chilichonse. Kutentha kozizira kwa masika kumabweretsa nyengo yofunda. M’madera ena kumatenga miyezi iwiri, pamene kwina kumatenga miyezi isanu ndi umodzi kapena kupitirirapo. Amatchedwa chirimwe.
Ndi chilimwe kumabwera kutentha. Kutentha kumatha kupangitsa kuti galimoto yanu ikhale yovuta kuyendetsa, ndichifukwa chake Packard adayambitsa zowongolera mpweya mu 1939. Kuyambira ndi magalimoto apamwamba ndipo tsopano akufalikira pafupifupi pafupifupi galimoto iliyonse yopangidwa, zoziziritsira mpweya zapangitsa oyendetsa ndi okwera kuzizira kwa zaka zambiri.
Kodi air conditioner imagwira ntchito bwanji?
Choyatsira mpweya chili ndi zolinga ziwiri zazikulu. Zimaziziritsa mpweya wolowa m'nyumba. Imachotsanso chinyezi kuchokera mumlengalenga, ndikupangitsa kuti ikhale yabwino mkati mwagalimoto.
Mumitundu yambiri, choziziritsa mpweya chimazimitsa chokha mukasankha njira yochepetsera. Imachotsa chinyezi kuchokera pa windshield, kupangitsa kuti mawonekedwe aziwoneka bwino. Nthawi zambiri mpweya wozizira sufunikanso pamene kusungidwa kwa defrost kumasankhidwa, choncho nkofunika kudziwa kuti mpweya wozizira ukugwira ntchito ngakhale kutentha kumasankhidwa pa gulu lowongolera.
Kodi ntchito?
Makina oziziritsira mpweya amagwira ntchito mofanana kuchokera kwa wopanga kupita kwa wopanga. Mitundu yonse ili ndi zigawo zina zofanana:
- compressor
- mawonekedwe
- valavu yowonjezera kapena chubu cha throttle
- wolandila/chowumitsira kapena batire
- evaporator
Mpweya woziziritsa mpweya umapanikizidwa ndi mpweya wotchedwa refrigerant. Galimoto iliyonse imatchula kuchuluka kwa firiji yomwe imagwiritsidwa ntchito kudzaza makinawo, ndipo nthawi zambiri simadutsa mapaundi atatu kapena anayi m'magalimoto onyamula anthu.
Compressor imachita zomwe dzina lake likunena, imakanikiza firiji kuchoka pa mpweya kupita kumadzi. madzi amazungulira mu refrigerant mzere. Chifukwa chakuti ili pansi kwambiri, imatchedwa mbali yothamanga kwambiri.
Njira yotsatira ikuchitika mu condenser. Firiji imadutsa mu gridi yofanana ndi radiator. Mpweya umadutsa mu condenser ndikuchotsa kutentha mufiriji.
Kenako refrigerant imayenda pafupi ndi valavu yowonjezera kapena chubu cha throttle. Vavu kapena kutsamwitsa mu chubu kumachepetsa kuthamanga kwa mzere ndipo refrigerant imabwerera ku mpweya.
Kenako, refrigerant imalowa mu chowumitsira chowumitsira, kapena cholumikizira. Apa, desiccant mu chowumitsa cholandirira amachotsa chinyezi chomwe chimatengedwa ndi firiji ngati mpweya.
Pambuyo pa chowumitsira chowumitsira, chowumitsa chozizira cha refrigerant chimadutsa mu evaporator, idakali mu mawonekedwe a mpweya. The evaporator ndi gawo lokhalo la mpweya dongosolo kuti kwenikweni mkati galimoto. Mpweya umawomberedwa kudzera mu evaporator pachimake ndipo kutentha kumachotsedwa mumlengalenga ndikusamutsira mufiriji, kusiya mpweya wozizirira ndikusiya evaporator.
Refrigerant imalowanso mu compressor. Njirayi imabwerezedwa nthawi zambiri.
