Kugona kwemufiriji hakugone kuzadzisa zvinodiwa zvemutoro wedhipoziti (kushanda zvakanaka kwecompressor kwakaderera)
Pane zvikonzero zviviri zvikuru zvekushaikwa kwehuwandu hwekutenderera kwefiriji. 
Chimwe ndechekuti muripo wemufiriji hauna kukwana, panguva ino, zvinongodiwa chete kuzadza huwandu hwakakwana hwemufiriji;
Chimwe chikonzero ndechekuti kune kudonha kwakawanda kwe refrigerant mu system, muchiitiko ichi, tinofanira kutanga tawana kudonha kwacho, totarisa pakutarisa kubatana kwepaipi nemavharuvhu, toona kudonha kwacho togadzirisa, tobva tachaja huwandu hwakakwana hwe refrigerant.
Kushaikwa kwenzvimbo yekuchengetera firiji (kusakwana kwechinhu chinotonhodza mufiriji)
Kusakwana kwe refrigerant mu system kuchakanganisa zvakananga kufamba kwe refrigerant mu evaporator. Kana expansion valve yakavhurika zvakanyanya, expansion valve haina kugadziriswa zvakanaka kana kuvharika. Kana refrigerant flow yakakura, evaporation pressure uye evaporation tembiricha inokwira, uye tembiricha yekuchengetera zvinhu inodzikira; panguva imwe chete, kana expansion valve iri diki kana kuti yakavharwa, refrigerant flow inodzikira, uye refrigerant capacity ye system inodzikira, uye tembiricha yekuchengetera zvinhu inodzikirawo. Kazhinji, tinogona kuona evaporation pressure, evaporation tembiricha uye frost ye suction pipe kuti tione kana refrigerant flow ye expansion valve yakakodzera. Kuvharika kwe expansion valve chinhu chakakosha chinokanganisa refrigerant flow, uye zvikonzero zvikuru zvekuvharika kwe expansion valve i ice blockage uye tsvina blockage. Ice blockage imhaka yekuti dryer effect haina kunaka, refrigerant ine mvura, uye kana ichiyerera ne expansion valve, tembiricha inodzikira kusvika pasi pe 0℃, mvura iri mufiriji inova chando yovhara buri revharuvhu remagetsi; kuvharika kwakasviba kunokonzerwa nekuti firita yekupinda yevharuvhu yekuwedzeredza ine tsvina yakawanda, uye firiji haisi kuyerera zvakanaka, zvichiita kuti ivhare.
Kuyerera kwemufiriji kwakakura zvakanyanya kana kuti kudiki zvakanyanya (vharuvhu yekutambanudza isina kugadziriswa zvakanaka kana kuti yakavharika)
Kuwanda kwemafuta ayo ekupisa kuchaderedzwa, kana chubhu yekupisa ye evaporator yave nemafuta akawanda emufiriji akabatana nechitarisiko chayo chemukati. Saizvozvowo, kana paine mhepo yakawanda muchubhu yekupisa, nzvimbo yekupisa ye evaporator inoderedzwa, uye kushanda kwayo kwekupisa kunoderedzwa zvakanyanya, uye tembiricha yekamuri yekuchengetera zvinhu inodzikira. Naizvozvo, kushanda kwezuva nezuva nekugadzirisa, kunofanirwa kutariswa kuti chubhu yekupisa ye evaporator ibvise mafuta panguva uye ibudise mweya mu evaporator, kuitira kuti ivandudze kushanda kwe evaporator.
Mhedzisiro yekufambisa kupisa inoderera (evaporator kana paine mhepo yakawanda kana mafuta anotonhora)
Izvi zvinonyanya kukonzerwa nekuti chando chekunze kwe evaporator chakakora zvakanyanya kana kuti guruva rakawandisa rinokonzerwa ne evaporator yekuchengetera inotonhora. Tembiricha yekunze ye evaporator inonyanya kuderera pane 0℃, zvichikonzera chimwe chikonzero chakakosha chekudzikira kwekupisa kweraibhurari ndechekuti kushanda zvakanaka kwekupisa kwemuchina we evaporator kwakaderera. Uye hunyoro hwemudura hwakakwira, hunyoro huri mumhepo huri nyore kuomesa chando kunze kwemuchina we evaporator, uye kunyange chando, zvichikanganisa mhedzisiro yekupisa kwemuchina we evaporator. Kuti chando chekunze chemuchina we evaporator chisanyanya kukobvu, chinofanira kunyungudutswa nguva nenguva.
Nzira mbiri dziri nyore dzekunyungudutsa chando dzinotevera:
①Mira kunyungudutsa chando. Kureva kuti, misa kushanda kwecompressor, vhura gonhi, rega tembiricha yeraibhurari ikwire, kuti inyungudike yega, wobva watangazve compressor.
②Kusviba kwechando. Mushure mekubvisa zvinhu mudura, sviba zvakananga pamusoro pechubhu ye evaporator row nemvura yepombi inopisa zvakanyanya kuti chando chinyungudike kana kudonha. Pamusoro pechando chakanyanya kukora chichaita kuti evaporator iwedzere kupisa, kutaridzika kwe evaporator nekuda kwekusacheneswa kwenguva pfupi uye kuunganidzwa kweguruva kwakanyanya kukora, kushanda kwayo kwekupisa kuchadzikirawo zvakanyanya.
Kutamiswa kwekupisa kunoderera (chando chekunze che evaporator chakanyanya kukora kana kuti guruva rakawanda kwazvo)
Kudzivirira kupisa uye kuvharira kwakashata, kushanda kwakashata kwekudzivirira kupisa kunokonzerwa nekuti ukobvu hwechivharira chepombi, madziro ekudzivirira ewarehouse, nezvimwewo hazvina kukwana. Izvi zvinonyanya kukonzerwa nekusarudzwa kusina kunaka kweukobvu hwechivharira chekudzivirira pakugadzira kana kuti zvinhu zvekudzivirira zvisina kunaka pakuvaka.
Pamusoro pezvo, maitiro ekuvaka nekushandisa, basa rekudzivirira hunyoro rinogona kukuvara zvichikonzera hunyoro hwekudzivirira, kushanduka, uye kunyange kuora, kugona kwayo kudzivirira hunyoro kunoderera, raibhurari inorasikirwa nekutonhora kunowedzera, uye kudonha kwetembiricha yeraibhurari kunoderera zvakanyanya.
Chimwe chikonzero chakakosha chekurasikirwa nechando ibasa rekuvhara rakashata remudura, mhepo inopisa yakawanda inobva mumhepo ichipinda mudura. Kazhinji, kana chisimbiso chemusuwo kana chisimbiso chechando chekuchengetedza chikavhara chisimbiso chemadziro panguva yekudzikira kwemvura, zvinoreva kuti chisimbiso hachina kusimba.
Pamusoro pezvo, kuvhurwa nekuvharwa kwemusuwo kakawanda kana vanhu vakawanda vachipinda mudura pamwe chete kunowedzerawo kurasikirwa nekuchengetwa kwemuchina unotonhora. Kana ukaedza kudzivirira kuvhurwa kwemusuwo kudzivirira mhepo inopisa yakawanda kupinda mudura. Ehe, dura rinopinda mudura kakawanda kana kuti mudura rakakura zvakanyanya, mutoro wekupisa unowedzera zvakanyanya, kuti utonhore kusvika patembiricha yakatarwa kazhinji zvinotora nguva yakareba.
Zvinokonzera kurasikirwa kukuru kwechando (nzvimbo yekuchengetera zvinhu inotonhora nekuda kwekusadzivirira zvakanaka kana kushanda zvakanaka kwekuvhara)
Ringi yecylinder nepiston nezvimwe zvikamu nekuda kwekusakara kwakanyanya, compressor nekuda kwekushanda kwenguva pfupi. Kana yakawedzerwa clearance, sealing function ichaderedzwawo, coefficient yecompressor yekuendesa mweya inoderedzwawo, kugona kwefiriji kunoderedzwa. Kana simba rekutonhodza riri pasi pemutoro wekupisa wewarehouse, zvichaita kuti tembiricha yewarehouse iderere zvishoma nezvishoma. Zvinogona kuonekwa nekuona kudzvanywa kwecompressor nekubuda kwemhepo kunotarisa kugona kwefiriji yecompressor. Kana simba rekutonhodza recompressor rikaderera, nzira yakajairika ndeyekutsiva compressor cylinder sleeve nepiston ring, kana kutsiva kuchiri kusashanda, zvimwe zvinhu zvinofanirwa kufungwa nezvazvo, uye kutoputsa muchina kuti uedze, kubvisa zvinhu zvinokanganisa.
