Muzhizha rinopisa kana kuti munguva yechando inotonhora, mhepo inotonhodza mota inokosha kwatiri vanofarira mota, kunyanya kana mahwindo akafukidzwa nemhute kana chando. Kugona kwemhepo inotonhodza mota kukurumidza kudzima nekunyungudutsa kunoita basa guru mukuchengetedza kutyaira. Kune mota dzemagetsi, dzisina injini yemafuta, hadzina nzvimbo yekupisa yekudziyisa, uye compressor haina simba rekufambisa injini kuti itonhodze. Saka mota dzemagetsi dzakachena dzinoita sei kuti mhepo inotonhodza uye itonhodze? Ngationei.
01 Zvikamu zveSisitimu Yekutonhodza Yemhepo
Zvinhu zviri mu air conditioner cooling system zvinosanganisira: electric compressor, condenser, pressure sensor, electronic expansion valve, evaporator, air conditioning hard pombi, mahosi, uye control circuit.
Kompresa:
Inotora refrigerant ine gasi rinodziya zvishoma uye rinodziya zvishoma uye inoidzvanya kuita gasi rine mvura inodziya zvakanyanya uye rinodziya zvakanyanya. Munguva yekumanikidzwa, mamiriro erefrigerant anoramba asina kuchinja, asi tembiricha nekumanikidzwa zvinoramba zvichiwedzera, zvichigadzira gasi rinodziya zvakanyanya.
Chinotonhodza:
Muchina uyu unoshandisa feni inotonhodza kuti ubvise kupisa kwemuchina unotonhodza uye une pressure yakakwira kumhepo yakapoteredza, uchitonhodza muchina uyu. Mukuita uku, muchina uyu unoshanduka kubva pakuva gasi kuenda pakuva mvura, uye unenge uri mumamiriro ekupisa uye ane pressure yakakwira.
Vharuvhu Yokuwedzera:
Refrigerant yemvura inopisa zvakanyanya uye ine kumanikidzwa kwakanyanya inopfuura nepavharuvhu yekutambanudza kuti idzore kumanikidzwa isati yapinda mu evaporator. Chinangwa cheiyi nzira ndechekutonhodza nekudzikamisa kumanikidzwa kwefiriji uye kudzora kuyerera kwemvura kuti idzore kugona kwekutonhodza. Refrigerant painopfuura nepavharuvhu yekutambanudza, inoshanduka kubva pakuva mvura inopisa zvakanyanya, ine kumanikidzwa kwakanyanya kuenda pakuva mvura inopisa zvishoma, ine kumanikidzwa kwakaderera.
Muchina wekupwanya mvura:
Mvura inotonhorera ine simba shoma uye ine simba shoma inobva muvharuvhu yekubuditsa mvura inonwisa kupisa kwakawanda kubva mumhepo yakapoteredza iri mu evaporator. Munguva iyi, firiji inoshanduka kubva pakuva mvura kuita gasi rine simba shoma uye rine simba shoma. Gasi iri rinozotorwa necompressor kuti ridzvanyirirwe zvakare.
Kubva pamaonero ekutonhodza, sisitimu yekutonhodza yemotokari dzemagetsi yakafanana neyemotokari dzechinyakare dzinoshandisa mafuta. Musiyano uripo zvakanyanya munzira yekufambisa yecompressor yekutonhodza mhepo. Mumotokari dzechinyakare dzinoshandisa mafuta, compressor inotyairwa nebhandi reinjini, nepo mumotokari dzemagetsi, compressor inodzorwa neelectronic control kuti ityaire mota, iyo inozoshandisa compressor kuburikidza necrankshaft.
02 Sisitimu Yekudziyisa Yemhepo Inotonhodza
Kunobva kupisa kunowanikwa zvikuru kuburikidza nePTC (Positive Temperature Coefficient). Mota dzemagetsi dzisina magetsi dzine mhando mbiri: PTC module yekupisa mhepo uye PTC module yekupisa mvura. PTC rudzi rwe semiconductor thermistor, uye hunhu hwayo ndehwekuti resistance yezvinhu zvePTC inowedzera sezvo tembiricha ichikwira. Pasi pemagetsi asingachinji, PTC heater inokurumidza kupisa patembiricha yakaderera, uye sezvo tembiricha ichikwira, resistance inowedzera, current inoderera, uye simba rinoshandiswa nePTC rinoderera, nokudaro richichengetedza tembiricha isingachinji.
Maumbirwo Emukati mePTC Module yeKudziyisa Mhepo:
Iine chinodzora (kusanganisira module yedhiraivha ine simba shoma/yakakwira), zvibatanidza zvewaya zvine simba rakawanda/rakaderera, firimu rekudzivirira kupisa rePTC, silicone pad inodziisa simba inofambisa kupisa, uye goko rekunze, sezvakaratidzwa mumufananidzo.
Module yePTC yekudziya mhepo inoreva kuisa PTC zvakananga pakati pesystem yemhepo inodziya yekabhini. Mhepo yekabhini inotenderedzwa nemhepo inofefetera uye inodziiswa zvakananga nePTC heater. Firimu rinodzivisa kupisa mukati memodule yePTC yekudziya mhepo rinofambiswa nemagetsi akawanda uye rinodzorwa neVCU (Vehicle Control Unit).
03 Kudzora Sisitimu Yekutonhodza Mhepo Yemotokari Yemagetsi
VCU yemotokari yemagetsi inounganidza zviratidzo kubva paA/C switch, A/C pressure switch, evaporator temperature, fan speed, uye ambient temperature. Mushure mekugadzirisa nekuverenga, inogadzira zviratidzo zvekudzora, izvo zvinotumirwa kune air conditioner controller kuburikidza neCAN bus. Air conditioner controller inodzora on/off yehigh-voltage circuit ye air conditioning compressor, sezvakaratidzwa mumufananidzo.
Izvi zvinopedzisa sumo huru yemhepo inotonhodza mota dzemagetsi. Wakazviwana zvichibatsira here? Tevedzera Yiyi New Energy Vehicles kuti uwane rumwe ruzivo rwehunyanzvi rwunogoverwa vhiki rega rega.
