Nzira dzekurapa kuvharika kwechando, kuvharika kwetsvina uye kuvharika kwemafuta mufiriji

Taura nesukuti zvikubatsire kugadzirisa dambudziko iri zvinobudirira

1. Kuvharika kwechando

Chikonzero chekukanganisa kwekuvhara kwechando

Chikonzero chikuru ndechekuti kune hunyoro hwakawanda musisitimu yekutonhodza. Nekutenderera kwefiriji nguva dzose, hunyoro huri mufiriji hunotanga kuzara paburiro revharuvhu rekuwedzera. Sezvo tembiricha iri paburiro revharuvhu rekuwedzera iri yakaderera, mvura inooma kuita chando uye inowedzera zvishoma nezvishoma. Kana yasvika padanho rakati, inovhara zvachose vharuvhu rekuwedzera uye firiji haigone kutenderera.

Nzvimbo huru dzinopa hunyoro mufiriji ndeidzi:

1. Pepa rinodzivirira injini riri mucompressor rine hunyoro, hunova ndihwo hunonyanya kukonzera hunyoro musystem.
2. Hunyoro hunosara muzvikamu uye mapaipi anobatanidza ehurongwa hwekutonhodza nekuda kwekuoma kwakakwana;
3. Mafuta emufiriji nefiriji zvine hunyoro hwakawanda kupfuura zvinobvumidzwa;
4. Munguva yekuunganidza kana kugadzirisa, pombi yacho inenge yakavhurika kwenguva yakareba, zvichiita kuti hunyoro huri mumhepo hunyudzwe nepepa rekudzivirira injini nemafuta emufiriji.

Nekuda kwezvikonzero zvataurwa pamusoro apa, huwandu hwemvura mufiriji inotonhorera hunopfuura huwandu hunobvumirwa hwefiriji inotonhorera, zvichikonzera kuvharika kwechando.

Kukanganiswa kwechando pafiriji

Kune rumwe rutivi, kuvharika kwechando kunoita kuti firiji isakwanise kutenderera, uye sisitimu yekufiriji haigone kuisa firiji zvakanaka; kune rumwe rutivi, hunyoro huchaitawo makemikari nefiriji kuti igadzire hydrochloric acid nehydrogen fluoride, zvichikonzera ngura kumapaipi esimbi nezvimwe zvikamu, uye zvichikonzera kukuvara kwekudzivirira kupisa kumawindings emota. Panguva imwe chete, zvichaitawo kuti mafuta ekufiriji ashaikwe uye kukanganisa mafuta ecompressor.

Kuonekwa kwekuvharika kwechando mufiriji ndeyekuti inoshanda zvakanaka pakutanga, chando chiri mu evaporator, kupisa kuri mu condenser, unit inofamba zvakanaka, uye ruzha rwekuita kwe refrigerant mu evaporator rwakajeka uye rwakagadzikana. Nekuumbwa kwevhariji yechando, kufamba kwemhepo kunogona kunzwika kuderera zvishoma nezvishoma uye nguva nenguva. Kana kuvharika kwacho kwakanyanya, ruzha rwekufamba kwemhepo runonyangarika, kufamba kwe refrigerant kunokanganiswa, uye condenser inotonhorera zvishoma nezvishoma.

Nekuda kwekuvharika kwechinhu ichi, kumanikidzwa kwemhepo inobuda mumhepo kunowedzera, ruzha rwekushanda kwemuchina rwunowedzera, hapana refrigerant inoyerera ichipinda mu evaporator, nzvimbo yechando inodzikira zvishoma nezvishoma, tembiricha inowedzera zvishoma nezvishoma, uye tembiricha yevharuvhu yekuwedzera inokwirawo pamwe chete, saka chando chinotanga kunyunguduka, uye refrigerant inotanga kutenderera zvakare. Mushure menguva yakati, kuvharika kwechando kunoitika zvakare, zvichiita chiitiko chekuvhara pass-blocking nguva nenguva.

Kubviswa kwekuvhara kwechando

Kuvharika kwechando kunoitika mufiriji nekuti mune hunyoro hwakawanda mufiriji, saka firiji yese inofanira kuomeswa. Pane nzira mbiri dzekugadzirisa nazvo:

1. Shandisa ovheni yekuomesa kuti upise uye uomese chikamu chimwe nechimwe. Nzira iyi ndiyo inonyanya kushanda mukubvisa kuvharika kwechando, asi inoshanda chete kune garandi yemugadziri wezvinhu zvinotonhora.
2. Shandisa nzira dzekupisa dzinoshandisa vacuum cleaner uye nzira dzechipiri dzekubvisa hunyoro kubva muchikamu chimwe nechimwe chefiriji.

2. Kuvharika kwetsvina

Chikonzero chekuvharika kwetsvina

Izvi zvinokonzerwa nekusvibiswa kwakanyanya mufiriji.

Kana tsvina neupfu zvikayerera nepafirita yakaoma, zvizhinji zvacho zvinobviswa nefirita yakaoma. Kana paine tsvina yakawanda mufirita yakaoma, tsvina shoma netsvina zvinounzwa muvharuvhu yekuwedzeredza nefiriji ine mwero wepamusoro wekuyerera, uye zvinochengetwa uye zvinounganidzwa muchikamu chacho nekusimba kukuru muchikamu chekukombama chevharuvhu yekuwedzeredza. Kusimba kuri kuramba kuchikura, zvichiita kuti zvive nyore kuti tsvina ichengetwe kusvika vharuvhu yekuwedzeredza yavharwa uye sisitimu yekuchengetera mvura isisakwanise kutenderera.

Pamusoro pezvo, daro riri pakati pevharuvhu yekutambanudza nefirita iri mufirita yakaoma rakaenzana, izvo zviri nyorewo kukonzera kuvharika kwakasviba; pamusoro pezvo, pakusanganisa vharuvhu yekutambanudza nefirita yakaoma, zviri nyorewo kusanganisa pombi yevharuvhu yekutambanudza.

Kukanganiswa kwetsvina pakuvharika kwefiriji

Kanasisitimu yekutonhodzaYakasviba uye yakavharwa, firiji haigone kutenderera, zvichiita kuti compressor irambe ichishanda, evaporator haitonhori, condenser haipisi, compressor shell haipisi, uye hapana ruzha rwemhepo iri mu evaporator.

Kana yakavharwa zvishoma, evaporator inonzwa ichitonhorera kana kuti ine chando, asi hapana chando. Paunobata pamusoro pekunze kwe filter dryer ne expansion valve, inonzwa ichitonhora zvikuru, yakaomeswa nechando, uye kunyange chando chichena chinoumbwa. Izvi zvinodaro nekuti kana refrigerant ikapfuura nepakati pe filter dryer kana expansion valve yakavharika zvishoma, inogadzira throttling uye pressure reduction effect, zvichiita kuti refrigerant ipfuure nepakati pe blockage ikure, iite utsi, uye itore kupisa, zvichikonzera condensation kana frost pamusoro pe blockage.

Musiyano uripo pakati pekuvharika kwechando nekuvharika kwetsvina:

Mushure menguva yekuvharika kwechando, firiji inogona kudzorerwa, zvichiita kuti dzimwe nguva ivhurike, dzimwe nguva ivharwe, ivharwe uye yozosunungurwa. Zvisinei, firiji haigone kuitwa mushure mekunge yavharwa netsvina.

Kugadzirisa matambudziko ekuvhara tsvina

1. Shandisa nitrogen ine simba rakawanda pamwe chete nedzimwe nzira dzekuburitsa tsvina muvharuvhu yekuwedzera yakavharika;
2. Kana vharuvhu yekuwedzeredza yapukutwa, chenesa uye omesa zvikamu zvese zviri mufiriji wozvibatanidzazve wozvibatanidza kuti pasave nedambudziko.
3. Kana vharuvhu yekutambanudza yakavharwa zvakanyanya, tsiva vharuvhu yekutambanudza kuti ubvise zvikanganiso.

3. Kuvharika kwemafuta uye kumwe kuvharika kwepombi

Chikonzero chekukanganisa kwekuvhara mafuta

Silinda yecompressor yakasakara zvakanyanya kana kuti nzvimbo iri pakati pepiston nesirinda yakakura zvakanyanya.

Chikonzero chekuvharika kwemamwe mapaipi ndeichi:

Pombi yacho inovharwa nechinhu chinosungirirwa panguva yekunamira; kana pombi painotsiviwa, pombi yacho pachayo inovharwa pasina kuonekwa. Nokudaro, inofanirwa kushanda nekutarisa zvinodiwa pakunamira nekutsiva pombi, kuitira kuti isakonzere kuvharika kwechinhu.

Kukanganiswa kwekuvhara kwemafuta pahurongwa hwefiriji

Peturu inoburitswa kubva mucompressor inoburitswa mucondenser, yobva yapinda mudryer filter pamwe chete nerefrigerant. Nekuda kwekusimba kwakanyanya kwemafuta, inovharwa nedesiccant iri mufiriji. Kana mafuta akawandisa, inoita kuti firiji ivharwe, zvekuti refrigerant haigone kutenderera zvakanaka uye system yekufiriji haigadzirise.

Kugadzirisa matambudziko ekuvhara mafuta

Mafuta ekutonhodza akawandisa asara mufiriji, izvo zvinokanganisa mhedzisiro yekutonhodza kana kutotadza kutonhodza. Saka, mafuta ekutonhodza ari mufiriji anofanira kucheneswa.

Kana sefa yavharwa nemafuta, sefa itsva inofanira kutsiviwa, uye nitrogen ine simba rakawanda inofanira kushandiswa kubvisa chikamu chemafuta ekutonhodza akaunganidzwa mu condenser. Kana nitrogen yaiswa, muchina wekuomesa bvudzi unogona kushandiswa kupisa condenser.
