1, chando pamusoro pefiriji che evaporator chakanyanya kukora kana kuti chakawandisa guruva, mhedzisiro yekufambisa kupisa inoderedzwa
Dura racho rakakora zvakanyanya kana kuti guruva rakawandisa. Sezvo tembiricha zhinji ye evaporator yefriji iri pasi pe 0 ℃, uye hunyoro hwakawanda hwemudura, hunyoro huri mumhepo huri nyore kuisa chando pamusoro pe evaporator, kana kuti kunyange chando, zvichikanganisa mafambiro e evaporator. Kuti chando che evaporator chisanyanya kukobvu, zvinodikanwa kuti chinyungudike nguva dzose.
Heano nzira mbiri dziri nyore dzekunyungudutsa: 1 kumisa chando. Kureva kuti, kumisa compressor kushanda, vhura gonhi remudura, kuitira kuti tembiricha yekuchengetera zvinhu ikwire, kuti inyungudike yega, wobva watangazve compressor. 1 Kutonhora. Mushure mekubvisa zvinhu mudura, bvisa zvakananga nemvura yepombi inodziya kuti ubvise pamusoro pechubhu ye evaporator, kuitira kuti chando chinyungudike kana kudonha. Pamusoro pechando chakakora chichaita kuti evaporator isashandise kupisa zvakanaka, pamusoro pe evaporator panenge pakanyanya kukobvu nekuda kwenguva refu isina kuchenesa uye guruva rakawanda, kushanda kwayo kwe heat transfer kuchadererawo zvakanyanya.
2, kuchengetwa kwechando mufiriji nekuda kwekusapisa zvakanaka kana kushanda kwekuvhara, zvichikonzera kurasikirwa kukuru kwechando
Kushanda zvisina kunaka kwekudzivirira kupisa kunokonzerwa nepaipi, ukobvu hwemadziro ekuchengetedza insulation mudura rekuchengetedza insulation hauna kukwana, insulation yekupisa uye mhedzisiro yekudzivirira kupisa haina kunaka, inonyanya kugadzirwa kuti isarudze ukobvu hwe insulation layer husakodzeri kana kugadzirwa kwemhando yezvinhu zvekudzivirira hakuna kunaka. Pamusoro pezvo, mukugadzirwa nekushandiswa, insulation yezvinhu zvekudzivirira uye kuramba hunyoro zvinogona kukuvara zvichikonzera hunyoro hwe insulation layer, deformation, kana kutoita vesiculation, insulation yayo yekupisa uye kugona kwayo kuchengetedza kupisa kudzikira, kurasikirwa nechando mudura rekuchengetedza insulation kunowedzera, kudonha kwekushisa mudura rekuchengetedza insulation cold storage raibhurari kunoderera zvakanyanya.
Chimwe chikonzero chakakosha chekurasikirwa nechando ndechekusashanda zvakanaka kwekuchengetedza imba yekuchengetera zvinhu, kune mhepo inopisa yakawanda inobva mukubuda kwemhepo ichipinda mudura. Kazhinji kana chisimbiso chiri mumusuwo wedura kana chisimbiso chekudzivirira kupisa kwekuchengetedza chiri mudura chikaonekwa pakaitika dew, zvinoratidza kuti chisimbiso hachina kusimba. Pamusoro pezvo, kuvhurwa nekuvharwa kwemusuwo wedura kakawanda kana vanhu vakawanda vachipinda mudura pamwe chete kunowedzerawo kurasikirwa nechando kwedura. Vanofanira kuedza kudzivirira kuvhura musuwo kudzivirira mhepo inopisa yakawanda kupinda mudura. Ehe, dura rinopinda mudura kakawanda kana mudura rakakura kwazvo, mutoro wekupisa unowedzera zvakanyanya, kuti utonhore kusvika patembiricha yakatarwa kazhinji zvinoda nguva yakareba.
3, vharuvhu ye throttle haina kudzorwa zvakanaka kana kuti yakavharika, kuyerera kwe refrigerant kwakakura zvakanyanya kana kuti kudiki zvakanyanya
Vharuvhu yeThrottle isina kudzorwa zvakanaka kana kuvharwa, inokanganisa zvakananga kuyerera kwerefrigerant ichipinda mu evaporator. Kana vharuvhu yeThrottle yakavhurika zvakanyanya, kuyerera kwerefrigerant kwakakura, kumanikidzwa kwekubuda kwemhepo uye tembiricha yekubuda kwemhepo inokwirawo, tembiricha yekuchengetera zvinhu inodzikisa mwero wekuderera; panguva imwe chete, kana vharuvhu yeThrottle yakavhurika diki kana kuti yakavharika, kuyerera kwerefrigerant kunodzikirawo, kugona kwerefrigerant yesystem kunodzikirawo, tembiricha yekuchengetera zvinhu inodzikisawo mwero wekuderera kwemhepo.
Kazhinji nekutarisa kumanikidzwa kwekubuda kwemvura, tembiricha yekubuda kwemvura uye chando chepombi yekusveta kuti uone kana kuyerera kwethrottle refrigerant kwakakodzera. Kuvharika kwethrottle chinhu chakakosha chinokanganisa kuyerera kwefiriji, zvichikonzera kuvharika kwethrottle ndicho chikonzero chikuru cheplug yechando uye plug yakasviba.
Kuvharika kwechando kunokonzerwa nekuti muchina wekuomesa hausi wakanaka, muchina wekuomesa une mvura, unoyerera nepavharuvhu yethrottle, tembiricha inodonha kusvika pasi pe0 ℃, hunyoro huri mufiriji huchipinda muchando uye hunovhara gomba rethrottle; kuvharika kwechando kunokonzerwa nekuunganidzwa kwetsvina yakawanda mu throttle valve, kuyerera kwefiriji hakuna kutsetseka, uye kuvharika kwechinhu chacho kunokonzereswa nekuumbwa kwetsvina.
4, kushanda zvakanaka kwecompressor yefriji kwakaderera, kugona kwefiriji hakugone kusangana nezvinodiwa zvemutoro wedura
Compressor yefiriji inokonzerwa nekushanda kwenguva refu, silinda liner ne piston ring nezvimwe zvikamu nekuda kwekusakara kwakanyanya, nekuwedzera kwekubvisa, kushanda kwe sealing kuchaderera zvinoenderana, coefficient ye refrigeration compressor gas transmission coefficient inoderedzwawo, kugona kwe refrigeration kuchaderedzwa. Kana simba rekutonhodza riri pasi pe thermal load ye warehouse, zvichaita kuti tembiricha ye warehouse iderere zvishoma nezvishoma.
Compressor inogona kuonekwa kuburikidza nekusveta nekudzvanywa kwecompressor, zvinonzwisisika kuti compressor inogona kudzikamisa sei kutonhora kwecompressor. Kana kutonhora kwecompressor kukadzikira, nzira yakajairika ndeyekutsiva compressor cylinder liner nepiston ring, kana kutsiva kuchiri kushanda, inofanira kufunga nezvezvimwe zvinhu, uye kutobvisa kugadzirisa muchina, pamwe nekubvisa matambudziko.
5, evaporator kana paine mhepo yakawanda kana mafuta efriji, mhedzisiro yekufambisa kupisa yakaderera
Kana chubhu yekupisa ye evaporator yabatanidzwa pamusoro pemafuta akaomeswa nechando, chiyero chayo chekupisa chichaderedzwa, zvakafanana, kana paine mhepo yakawanda muchubhu yekupisa, nzvimbo yekupisa ye evaporator inoderedzwa, kushanda kwekupisa kuchaderedzwawo zvakanyanya, tembiricha yekamuri yekuchengetera zvinhu inoderedza mwero wekuderera. Naizvozvo, mukushanda nekuchengetedza kwezuva nezuva, kutarisirwa kunofanirwa kupihwa pakubviswa kwemafuta epamusoro echubhu yekupisa ye evaporator nekuburitswa kwemhepo mu evaporator panguva yakakodzera, kuitira kuvandudza kushanda kwekupisa kwe evaporator.
6, huwandu hwe refrigerant mu system hauna kukwana, kugona kwe refrigerant hakuna kukwana
Kusakwana kwekutenderera kwe refrigerant kunonyanya kukonzerwa nezvikonzero zviviri, chimwe ndechekuti refrigerant chaji haina kukwana, panguva ino, kungoda kuzadzisa huwandu hwakazara hwe refrigerant. Chimwe chikonzero ndechekuti system refrigerant leakage yakawanda, muchiitiko ichi, unofanira kutanga wawana nzvimbo yekubuda, uchitarisa pakuongorora mapaipi, kubatana kwevharuvhu, kuwana nzvimbo yekubuda leakage, uye wobva wachaja huwandu hwakazara hwe refrigerant.
