Sei mhepo yemota yangu ichifuridzira mweya unopisa?
Zviri mukati
Imotokari yemhepo yemhepo haigoni kukundikana kamwe kamwe, asi inowanzoitika nguva yezhizha isati yatanga. Dzimwe nguva nekuda kwekushaikwa kwekudzivirira kwakakodzera, asi kuparara kunoitikawo. Diagnostics ichadikanwa, sezvo paine zvikonzero zvakawanda.
Mhepo inopisa inoyerera riini kubva kumhepo inofefetera kuenda kumota?
Sechikamu cheiyo mweya yekutonhodza system, kune zvakawanda zvingangove zvisingavimbike zvikamu uye zvikamu:
- compressor ine electromagnetic clutch uye idling inobereka;
- condenser (radiator) mubhuroka ine mainjini inotonhorera radiator uye mafeni;
- filter-drier pane radiator;
- mitsetse yakakwirira uye yakaderera, inowanzogadzirwa nematete-walled aluminium tubes neO-rings;
- refrigerant (freon), iyo inosanganisira mafuta ekuzora hurongwa kubva mukati;
- valve-regulator;
- evaporator muchimiro chesaloon radiator;
- control system ine sensors uye switch;
- yakaoma yemhepo ducts uye dampers ine control actuators.
Kazhinji, evaporator inowanikwa mune imwechete air conditioning unit ine hita radiator, mavharuvhu haawanzo kuisirwa mumvura inoyerera, saka hazvishamisi kuti kana paine kukundikana, mhepo inotonhora inogona kushanduka ichipisa. Asi muzhizha, chero mhepo inotonhodzwa kana zvinhu zvese zvakarongeka kana kudziya kana paine kusashanda zvakanaka.
Low refrigerant
Paunenge uchiwedzera hurongwa, yakanyatsotsanangurwa huwandu hwefreon uye lubricant inoputirwa mairi. Izvo hazvichagoneki nekuda kwenjodzi yekukuvadzwa, kune zvakare incompressible yemvura chikamu chefiriji muhurongwa, uye kana pasina mutakuri akakwana, ipapo kupisa kwekushisa kunoderedzwa zvakanyanya.
Panogona kuva nezvikonzero zvakawanda zvekushaikwa kwefreon:
- zvikanganiso kana refueling sisitimu;
- iyo system yakashanda kwenguva yakareba pasina refueling;
- kudonha kwakaitika nekuda kwekurasikirwa kwekusimba nemapaipi kana zvisimbiso.
Kana dambudziko rakamuka kamwe kamwe, saka zvakakosha kutsvaga kudonha, kana zvishoma nezvishoma nekufamba kwenguva, zvino zvakakodzera kutanga ne refueling.
Weak condenser kutonhora
Radiator yeair conditioner yakagadzirirwa kutonhora nekuyerera kwechisikigo kana kumanikidzwa nefani. Sezvo mutemo, fan inotendeuka panguva imwe chete nemhepo inogadzirisa, nokuti mukupisa uye muhupo hwehutu hunopisa huri pedyo, mhepo inoyerera haina kukwana chero ipi zvayo.
Kana iyo feni ikatadza, kana pamusoro peiyo condenser huchi chimiro chakasviba zvakanyanya, ipapo kutonhora kwekumanikidza hakubatsiri.
Compressor kukundikana
Iyo compressor inoenderana nekupfeka kwechisikigo uye kubvaruka. Chekutanga pane zvese, iyo electromagnetic friction clutch inobatanidza drive pulley kune compressor shaft inotambura. Kupfeka kwechikamu chekupomba hakugadziriswi nekugadzirisa, zvakakosha kutsiva chikwata chacho chose.
Iyo yekubatanidza inogona kutsiviwa, spare parts inowanikwa. Kudzivirira kutsiva kutakura kwayo kunokurudzirwa kana ruzha runoonekwa ruchionekwa.
Nehupenyu hurefu hwebasa, iyo pulley inoperawo, iyo inozviratidza mukutsvedza kwebhandi idzva rine tension chaiyo.
Wiring
Kuti uite shanduko yakakodzera yeair conditioner units, zvinodikanwa kuve nemagetsi ese ekupa, mabatiro ane pasi, serviceability yeiyo control unit, sensors uye switch.
Wiring corrodes nekufamba kwenguva, mazita anogona kupera mune chero dunhu. Cheki inosvika pakuenderera kwe wiring, kutonga kwekuvapo kwemasimba ese uye kutonga kwemagetsi. Kubatana kunofanirwa kuve kwakabatana zvakajeka kana air conditioner yaitwa.
Chitofu dampers uye regulators
Kana iyo freon compression uye evaporation system iri kushanda zvakajairwa, iyo inotarwa nemusiyano wekushisa pakati pekugovera uye mitsara yekudzoka, ipapo kusashanda kunofanirwa kutariswa mumhepo yekugovera system yeair conditioning unit.
Iyo yemamiriro ekunze module mu kabhini ine nhamba huru yepurasitiki air ducts uye inodzorwa madhamu. Vanofanira kunge vakavharwa zvakachengeteka uye vachifamba vane chivimbo pasi pekutonga kwe mechanical tsvimbo, tambo uye servos yemagetsi.
Nekufamba kwenguva, madhiraivha anotadza, matanda anogona kudonha uye kudzima munzvimbo yematipi, uye iwo madhiraivha pachawo anokanganisa uye anorasikirwa nezvisimbiso zvawo.
Kugovera kwemhepo kunotanga nenzira dzisina kujairika, izvo zvinongoonekwa nekushanduka kwekushisa munzvimbo yezvinobuda zvinobuda pamazinga akasiyana pakureba.
Nzira yekuwana sei chikonzero nei air conditioner ichivhuvhuta mweya unodziya
Chokutanga pane zvose, zvakakosha kuparadzanisa nzvimbo yekutsvaga mumigwagwa yekugadzira kusiyana kwekushisa pakati pe condenser uye evaporator uye air flow control system.
Yokutanga inosanganisira compressor, radiators, valve uye mapaipi, yechipiri - mhepo ducts uye dampers. Electronics inoshandisa zvose zvikamu zvehurongwa.
Kuongorora mafizi
Maseketi emagetsi emidziyo yese ine chekuita nemhepo inofefetera anogona kuchengetedzwa neimwe kana kupfuura fuse.
Ruzivo pamusoro peizvi nenzvimbo yazvo runogona kuwanikwa murelay uye fuse placement tables inowanikwa mugwaro rinoperekedza mota.
Mafusi anogona kubviswa uye kutariswa nemultimeter ohmmeter kana kungova chiratidzo chemwenje nekuibatanidza munhevedzano kune ese materminals esoketi ine fuse inopinzwa mairi. Inoisa iyo ine oxidized kana kukanganisa nekuda kwekupisa inofanira kutsiviwa.
Fuse inogona kukundikana pachayo, asi kazhinji inovhuvhuta kubva kupfupi maseketi mudunhu raanodzivirira. Kudzora kwekuona kwe wiring uye kuenderera kwenzvimbo dzinofungirwa kuchabatsira.
Computer kuongororwa
Iwe unogona kuverenga uye kutarisa zvikanganiso zvekudzora mhepo uchishandisa scanner yakabatana neiyo mota diagnostic yekubatanidza.
Mushure mekuratidza kukanganisa kwakananga nema sensors, anotariswa ega pamwe chete ne wiring. Kupwanya, mapfupi maseketi kana kubuda kwezviratidzo kubva kune yakatarwa renji zvinogoneka. Kuve neruzivo rwakashata, iyo control unit inoramba kubatidza compressor.
Tsvaga freon leaks
Iwe unogona kutarisa kudonha kwefiriji nekuona, uchishandisa kuvepo kwemafuta asina kuomeswa mukuumbwa kwayo kana kushandisa ultraviolet tochi.
Chinhu chechiratidzo chinowedzerwa kune freon, iyo inoshandura mwenje weUV kuita mwenje unooneka kana migwagwa mikuru yakavhenekerwa, nzvimbo yekuvuza ichaonekwa zvakajeka. Iwe unogona kugezesa imba yeinjini, nekuti nekudonha kwenguva refu zvese zvinopenya.
Tarisa condenser
Iyo air conditioner radiator inotadza kana nekuda kwekuora mwoyo uye kudonha, kana kuvhara netsvina yemumugwagwa. Kana paine kumanikidzwa muhurongwa, iyo freon haibvi, iyo condenser inodziya zvakaenzana, saka zvakanyanya kutyora kwekupisa kwekutamisa nekuda kwekuvhara kwechimiro chehuchi.
Zvakanakisa kubvisa radiator, kupuruzira zvakanyanya pasi pekumanikidzwa kudiki, uye kudzorera nezvisimbiso zvitsva, kuzadzazve sisitimu. Sefa yekuomesa inotsiviwa neimwe itsva.
Kuongorora iyo compressor drive
Iwe unogona kutarisa kushanda kweclutch nekushandisa voltage zvakananga kune chinongedzo chemagetsi ayo. Inofanira kuvhara, iyo pulley inopinda mukubatana kwakavimbika ne compressor rotor. Izvi zvichaonekwa nekuwedzera kuramba kutenderera kana bhandi rekutyaira rabviswa.
Compressor Diagnostics
Kana mushure mekutarisa kushanda kwe clutch pane kusava nechokwadi pamusoro pekushanda kwe air conditioner, saka kushanda kwayo kuri nyore kutarisa panguva yekuwedzera refueling.
Iyo yekuzadza station station ine control pressure gauges yakabatana nemitsara, imwe yacho inoratidza kudzvanywa kwakagadzirwa necompressor mumutsara wekumanikidza.
Kana kuti zviri nyore - mushure mekunge compressor yaitwa, machubhu ekubuda kwayo anofanira kukurumidza kutanga kudziya, asi kuita kwayo kunogona kuongororwa nemazvo chete neruzivo rwakakura.
Fan check
Iyo feni inofanirwa kubatika kana air conditioner yaitwa uye ichimhanya ichienderera nekuderera. Kana basa rakadaro risina kupiwa, saka iwe unogona kuve nechokwadi chokuti motokari yayo yemagetsi uye magetsi emagetsi ari mumamiriro akanaka nekubvisa chibatanidza kubva kune injini yekushisa sensor.
Mushure meizvozvo, iyo yekudzora unit inoona izvi sekupfuura tembiricha muganho uye wobatidza mafeni. Neparutivi, mota inogona kutariswa nekupa simba kubva kubhatiri kune yayo yekubatanidza ine zvidimbu zvakakodzera zvewaya.
Kuongorora madhamu emamiriro ekunze
Kusvika kune ma dampers kwakaoma, saka kuti uvatarise iwe uchafanirwa kuparadzanisa kumberi kwekabhini. Nzira yacho yakaoma uye ine ngozi pakuti zviri nyore kukuvadza marashi epurasitiki kana kusunungura zvisimbiso, mushure mokunge mamwe manzwi uye kurira kuchaonekwa.
Iyo air duct system pachayo dzimwe nguva yakaoma uye yakashongedzerwa nemagetsi madhiraivha, iyo diagnostics iyo inoda control scanner ine masevhisi zvirongwa. Basa iri rakasiiwa kune nyanzvi dzemagetsi.
Pamwe chete nekugadziriswa kwechikwata chekutonga, umo ma-conductor emapuranga akadhindwa anowanzoita corrode uye solder joints kuputika. Tenzi achakwanisa kutengesa zvakakanganiswa uye kudzoreredza makwara akadhindwa.
