Sei inotonhora yekuchengetedza compressor frosting?

1-Kutonhora midziyo yekuchengetera: Frost pane compressor inodzosera mhepo chiteshi inoratidza kuti compressor inodzosa tembiricha yemhepo yakadzikira. Saka chii chichaita kuti compressor idzose tembiricha yemhepo kuve yakaderera?

Zvinonyatsozivikanwa kuti kana vhoriyamu uye kumanikidzwa kwemhando imwechete yefriji yakashandurwa, kutonhora kuchava nekuita kwakasiyana. Ndiko kuti, kana iyo refrigerant yemvura inobata kupisa kwakawanda, kudzvinyirira, kutonhora uye huwandu hwehumwe hutano hwefiriji huchava hwakakwirira. Kana kupisa kwekupisa kuri kushoma, kudzvanywa, tembiricha uye vhoriyamu zvichave zvakaderera.

Kureva kuti, kana iyo compressor inodzoka tembiricha yemhepo yakadzikira, inowanzoratidza yakaderera kudzoka kwemhepo kumanikidza uye yakakwirira refrigerant vhoriyamu yevhoriyamu imwechete. Mhedzisiro yemamiriro ezvinhu aya ndeyekuti firiji inoyerera kuburikidza ne evaporator haigoni kutora kupisa kunodiwa kuti iwedzere kune iyo yakafanotemerwa kudzvanywa uye kukosha kwekushisa, zvichikonzera kuderera kwekushisa kwemhepo, kudzvinyirira uye huwandu hwehuwandu.

Pane zvikonzero zviviri zvedambudziko iri:

1. The throttle valve liquid refrigerant supply yakajairika, asi evaporator haigoni kutora kupisa kazhinji kuti ipe kuwedzera kwefiriji.

2. Iyo evaporator inobata kupisa kazhinji, asi throttle valve refrigerant supply yakawandisa, kureva kuti, firiji inoyerera yakawandisa. Isu tinowanzozvinzwisisa seyakawandisa fluorine, kureva kuti yakawandisa fluorine inokonzeresa kuderera.

2- Kutonhora kuchengetedza midziyo: Frosting yecompressor inodzosera mweya nekuda kwekusakwana fluorine

1. Nekuda kwekuderera kwakanyanya kwekuyerera kwefiriji, iyo firiji inotanga kuwedzera munzvimbo yekutanga inokwidziridzwa mushure mekuyerera kubva kumucheto kumashure kweiyo throttle valve. Mazhinji echando pamusoro pemusoro wekugovera mvura kumucheto kumashure kwevhavha yekuwedzera inowanzokonzerwa nekushaikwa kwefluorine kana kusakwana kwekuyerera kwevhavha yekuwedzera. Kuwedzera kushoma kwefiriji hakuzoshandise iyo evaporator nzvimbo yese, uye tembiricha yakaderera chete ndiyo inoumbwa munharaunda mune evaporator. Dzimwe nzvimbo dzinokura nekukurumidza nekuda kwehushoma hwefiriji, zvichiita kuti tembiricha yenzvimbo iderere zvakanyanya, zvichikonzera evaporator frost.

Mushure mechando chemunharaunda, nekuda kwekuumbwa kwechidzitiro chekudzivirira pamusoro pe evaporator uye kupisa kwakadzika kuchinja munzvimbo ino, kuwedzera kwefiriji kuchaendeswa kune dzimwe nzvimbo, uye evaporator yose ichaita zvishoma nezvishoma chando kana kutonhora. Iyo yose evaporator ichaumba insulation layer, saka kuwedzera kuchapararira kune compressor kudzoka pombi, zvichiita kuti compressor idzose mweya kune chando.

2. Pamusana pehuwandu hushoma hwefiriji, iyo evaporator evaporation pressure yakaderera, zvichiita kuti kuderera kwekushisa kwemhepo, zvishoma nezvishoma kunokonzera kuti evaporator iwedzere uye iite ganda rekudzivirira, uye nzvimbo yekuwedzera ichaendeswa kune compressor kudzoka kwemhepo, zvichiita kuti compressor idzoke mhepo kune chando. Mapoinzi ese ari pamusoro acharatidza kuti evaporator yarohwa nechando mweya wekudzosa compressor usati warohwa nechando.
Muchokwadi, muzviitiko zvakawanda, kune chiitiko chechando, iwe unongoda kugadzirisa inopisa gasi bypass valve. Iyo chaiyo nzira ndeyekuzarura chivharo chekumashure chevhavha inopisa gasi, uye ipapo shandisa No. Nzira yekugadzirisa haifaniri kunge yakakurumidza. Kazhinji, ichambomira mushure mekushandura hafu yedenderedzwa. Rega sisitimu imhanye kwechinguva kuti uone mamiriro echando usati wafunga kuti urambe uchigadzirisa. Mirira kusvikira kushanda kwakasimba uye frosting phenomenon ye compressor inonyangarika isati yasimbisa chivharo chekupedzisira.
Kune mamodheru ari pazasi pe15 cubic metres, sezvo pasina gasi rinopisa rinopfuura vharafu, kana chiitiko chechando chakakomba, kudzvanywa kwekutanga kweiyo condensing fan pressure switch kunogona kuwedzera zvakafanira. Iyo chaiyo nzira ndeyekutanga kuwana yekumanikidza switch, bvisa chidimbu chidiki chekumanikidza switch kugadzirisa nati, uye wozoshandisa muchinjiko screwdriver kutenderera wachi. Kugadziriswa kwese kunodawo kuitwa zvishoma nezvishoma. Gadzirisa iyo hafu yedenderedzwa kuti uone mamiriro acho usati wafunga kana uchigadzirisa.
