1. Chando chiri pamusoro pemuchina wekudziya mufiriji chakanyanya kukobvu kana kuti pane guruva rakawandisa, uye simba rekufambisa kupisa rinoderera
Chimwe chikonzero chakakosha chekudzikira kwekupisa kwekuchengetera zvinhu inyaya yekuti evaporator haishande zvakanyanya, izvo zvinonyanya kukonzerwa nechando chakakora kana guruva rakawanda pamusoro pe evaporator. Sezvo tembiricha ye evaporator iri mufiriji inotonhorera iri pasi pe0 ℃, uye hunyoro mudura iri hwakanyanya, hunyoro mumhepo hunogona kuomeswa nechando kana kutoomeswa nechando pamusoro pe evaporator, izvo zvinokanganisa kupisa kwe evaporator. Kuti chando chepamusoro che evaporator chisanyanya kukobvu, chinofanira kunyungudutswa nguva nenguva. Nzira mbiri dziri nyore dzekunyungudutsa dzinotaurwa pazasi: ① Mira kunyungudutsa. Kureva kuti, misa kushanda kwe compressor, vhura musuwo wedura, rega tembiricha yedura ikwire, uye tangazve compressor mushure mekunge chando chanyunguduka. ② Sukurudza kirimu. Mushure mekubvisa zvinhu mudura, sukurudza zvakananga pamusoro pepombi ye evaporator nemvura yepombi ine tembiricha yakakwira kuti unyungudutse kana kudonha kubva muchando. Pamusoro pekusagona kutamisa kupisa kwemuchina we evaporator nekuda kwechando chakakora, kushanda zvakanaka kwemuchina we evaporator kuchadererawo zvakanyanya nekuda kwekuwanda kweguruva pamusoro pemuchina we evaporator nekuti hauna kucheneswa kwenguva yakareba.
2. Nekuda kwekusadzivirira kupisa zvakanaka kana kushanda zvakanaka kwekuvhara, nzvimbo yekuchengetera inotonhora mufiriji ine kurasikirwa kukuru kwekukwanisa kutonhora
Kusashanda zvakanaka kwekudzivirira kupisa kunokonzerwa nekusakwana kweukobvu hwechikamu chekudzivirira kupisa chemapaipi nemadziro ekudzivirira kupisa ewarehouse, uye kushomeka kwekudzivirira kupisa uye mhedzisiro yekudzivirira kupisa. Izvi zvinonyanya kukonzerwa nekusasarudzwa zvakanaka kweukobvu hwechikamu chekudzivirira kupisa panguva yekugadzira kana kunaka kwezvinhu zvekudzivirira kupisa panguva yekuvaka. Pamusoro pezvo, mukugadzirwa nekushandiswa, kudzoreredza kupisa uye kushanda kwekudzivirira hunyoro kwezvinhu zvekudzivirira kupisa zvinogona kukuvara, zvichikonzera kuti chikamu chekudzivirira kupisa chive chakanyorova, chakakanganisika, kana kutoora. Chimwe chikonzero chakakosha chekurasikirwa kukuru kwekutonhorera ndiko kusashanda zvakanaka kwekuchengetedza imba, uye mhepo inopisa yakawanda inopinda mudura kubva pakubuda kwemvura. Kazhinji, kana paine kuvharwa kwechikamu chekuvhara chemusuwo wedura kana kuvharwa kwemadziro ekudzivirira kupisa echando, zvinoreva kuti kuvharwa hakuna kusimba. Pamusoro pezvo, kuvhurwa nekuvharwa kwemusuwo wedura kakawanda kana vanhu vakawanda vanopinda mudura pamwe chete kunowedzerawo kurasikirwa kwesimba rekutonhodza mudura. Dzivisa kuvhura musuwo wedura zvakanyanya sezvinobvira kudzivirira mweya wakawanda unopisa kuti usapinde mudura. Ehe, kana imba yekuchengetera zvinhu ichiwanzoiswa zvinhu kana kuti zvinhu zvakawanda, kupisa kunowedzera zvakanyanya, uye kazhinji zvinotora nguva yakareba kuti zvitonhore kusvika patembiricha yakatarwa.
3. Vharuvhu yethrottle haina kugadziriswa kana kuvharwa zvisizvo, uye kuyerera kwerefrigerant kwakakura zvakanyanya kana kuti kudiki zvakanyanya
Kugadziriswa kusina kunaka kana kuvharika kwevharuvhu remagetsi kunokanganisa zvakananga kuyerera kwefiriji mu evaporator. Kana vharuvhu remagetsi rakavhurika rakakura kwazvo, mwero wekuyerera kwefiriji wakakura zvakanyanya, kumanikidzwa kwekubuda kwemhepo nekupisa kwekubuda kwemhepo zvichawedzerawo, uye mwero wekudonha kwekupisa kwewarehouse uchaderera; panguva imwe chete, kana vharuvhu remagetsi rakavhurwa riri diki kana kuti rakavharika, mwero wekuyerera kwefiriji unoderedzwawo, kugona kutonhora kwesystem kunoderedzwawo, uye mwero wekudonha kwekupisa kwewarehouse uchadererawo. Kazhinji, zvinogona kutongwa kana mwero wekuyerera kwefiriji wevharuvhu remagetsi wakakodzera nekutarisa kumanikidzwa kwekubuda kwemhepo, tembiricha yekubuda kwemhepo uye mamiriro echando epombi yekusveta. Kuvharika kwevharuvhu remagetsi chinhu chakakosha chinokanganisa kuyerera kwefiriji. Zvikonzero zvikuru zvekuvharika kwevharuvhu remagetsi ivharuvhu rechando uye kuvharika kwakasviba. Kuvharika kwechando kunokonzerwa nekuoma kwemuchina wekuomesa, uye muchina wekuomesa une hunyoro. Kana ichiyerera nepa throttle valve, tembiricha inodzikira pasi pe 0 °C, uye hunyoro huri mufiriji hunooma kuita chando uye hunovhara buri re throttle valve; kuvharika kwakasviba kuripo. Nekuda kwekuungana kwetsvina yakawanda pa filter screen pakupinda kwe throttle valve, kuyerera kwe refrigerant hakuna kutsetseka, zvichikonzera kuvharika.
4. Kushanda zvakanaka kwecompressor yekutonhodza kwakaderera, uye kugona kutonhora hakugone kuzadzisa zvinodiwa nemutoro wemudura
Nekuda kwekushanda kwenguva refu kwecompressor yekutonhodza, silinda neringi yepiston nezvimwe zvikamu zvakasakara zvakanyanya, uye clearance inoenderana inowedzera, mashandiro ekuvharira achadzikira zvinoenderana, gas transmission coefficient yecompressor yekutonhodza ichadzikirawo, uye kugona kutonhodza kuchadzikira. Kana kugona kutonhodza kuri pasi pekupisa kwemudura, tembiricha yemudura ichadzikira zvishoma nezvishoma. Kugona kutonhodza kwecompressor kunogona kutariswa nekutarisa kumanikidzwa kwekusveta nekuburitsa kwecompressor. Kana kugona kutonhodza kwecompressor kukadzikira, nzira inowanzoshandiswa ndeyekutsiva silinda neringi yepiston yecompressor. Kana kutsiva kuchiri kusashanda, zvimwe zvinhu zvinofanirwa kufungwa nezvazvo, kana kutoputsa nekugadzirisa, uye kugadzirisa matambudziko.
5. Mu evaporator mune mhepo yakawanda kana mafuta ekutonhodza, uye kupisa kunodzikira.
Kana oiri yekutonhodza yabatanidzwa zvakare pamusoro pechubhu yekupisa ye evaporator, chiyero chayo chekupisa chichaderera. Saizvozvowo, kana paine mhepo yakawanda muchubhu yekupisa, nzvimbo yekupisa ye evaporator ichaderedzwa, uye kupisa kwayo kuchaderedzwa. Kushanda zvakanaka kuchadererawo zvakanyanya, uye mwero wekudonha kwekupisa kwewarehouse uchaderera. Naizvozvo, mukushanda nekuchengetedza kwezuva nezuva, kutarisirwa kunofanira kupihwa pakubviswa kwemavara emafuta panguva yakakodzera pamusoro pechubhu yekupisa ye evaporator uye kuburitswa kwemhepo mu evaporator kuti kuvandudzwa kwekushanda kwekupisa kwe evaporator.
6. Huwandu hwe refrigerant mu system hauna kukwana, uye kugona kutonhora hakuna kukwana
Pane zvikonzero zviviri zvikuru zvekusakwana kwekufambisa kwemuchina wekuisa mufiriji. Chekutanga, muripo wemufiriji hauna kukwana. Panguva ino, huwandu hwakakwana hwemufiriji hunofanira kuwedzerwa. Chimwe chikonzero ndechekuti kune kudonha kwakawanda kwemufiriji musystem. Muchiitiko ichi, unofanira kutanga wawana panobuda mvura, wotarisa pakubatanidza kwepombi yega yega nevharuvhu, wozozadza huwandu hwakakwana hwemufiriji mushure mekugadzirisa zvikamu zvakabuda mvura.
