Cold storage iimba yekuchengetera inoshandisa zvivakwa zvekutonhodza kugadzira hunyoro hwakakodzera uye tembiricha yakaderera. Iyo inozivikanwawo se cold storage. Ndiyo nzvimbo iyo zvigadzirwa zvinogadziriswa uye kuchengetwa. Inogona kubvisa pesvedzero yemamiriro ekunze uye kurebesa nguva yekuchengetedza yezvakasiyana zvigadzirwa kuti zvigadzirise kuwanikwa kwemusika.
Chinangwa cheiyo inotonhora yekuchengetedza firiji system:
Kushanda musimboti wefiriji system Chinangwa chefiriji kushandisa dzimwe nzira kuendesa kupisa kwechinhu chakabatanidzwa chekuchengetera chinotonhora kunzvimbo yepakati pemvura kana mhepo, kuitira kuti tembiricha yechinhu chakatonhodzwa ichidzikiswe pasi petembiricha yepakati uye ichengetedzwe mukati menguva yakatarwa. tembiricha.
Cold kuchengetedza firiji system kuumbwa:
Iyo yakazara vapor compression refrigeration system inofanirwa kusanganisira refrigerant circulation system, lubricating oil circulation system, defrosting system, inotonhorera yekutenderera kwemvura system uye refrigerant circulation system, nezvimwe.
Nekuda kwekuoma uye hunyanzvi hwefiriji system yekuchengetedza inotonhora, zvimwe zvikanganiso zvakajairika zvinozoitika panguva yekushanda.
| Cold storage kutonhora system kutadza | Chikonzero

| Refrigerant leakage | Mushure mekudonha kwefiriji muhurongwa, simba rekutonhodza harina kukwana, kusveta uye kupera simba kwakadzikira, uye iyo inopindirana "inotsveta" inoyerera inonzwika yakakura kupfuura yakajairika inogona kunzwika pavharuvhu yekuwedzera. Hapana chando kana chando chidiki chinoyangarara pamusoro peevaporator. Kana gomba revharuvhu rekuwedzera rakakurisa, kudzvanya kuchiri kusachinja zvakanyanya. Mushure mekuvhara, iyo equilibrium pressure musystem inowanzodzika pane saturation pressure inoenderana neambient tembiricha yakafanana.

| Kunyanya kubhadharisa refrigerant mushure mekugadzirisa | Huwandu hwefiriji inobhadhariswa mufiriji system mushure mekugadzirisa kunopfuura kugona kwehurongwa, uye refrigerant inotora imwe vhoriyamu yecondenser, inoderedza kupisa kwekupisa nzvimbo, uye kuderedza kutonhora. Kusveta uye kupera simba kunowanzo kukwira pane yakajairika kumanikidza kukosha, evaporator haina chando chakasimba, uye kutonhora muimba yekuchengetera kunononoka. |
| Pane mweya mufiriji system | Mhepo iri mufiriji system ichaderedza kushanda kwefiriji. Chiitiko chiri pachena ndechekuti kusveta uye kupera simba kunowedzera (asi kupera kwemhepo hakuna kudarika kukosha kwakarongwa), uye iyo compressor inobuda kune condenser inlet Kupisa kunowedzera zvakanyanya. Nekuda kwekuvapo kwemhepo muhurongwa, dhizaini yekupera uye tembiricha yekupera inowedzera. |
| Low compressor kunyatsoshanda | Iko kuderera kwekushanda kwefiriji compressor inoreva kuti iyo chaiyo inopera vhoriyamu inoderera uye simba refiriji rinoderera zvichienderana kana mamiriro ekushanda anoramba asina kuchinjwa. Ichi chiitiko chinowanzoitika mumacompressor akashandiswa kwenguva refu. Kupfeka uye kubvarura kwema compressors makuru, kuenzana kwemvumo yechikamu chimwe nechimwe yakakura, uye kuvharidzirwa kwevhavha yemhepo kunoderedzwa, zvichiita kuti kuderera kwehuwandu hwemhepo inopera. |
| Frost iri pamusoro peevaporator yakanyanya kukora | kushandiswa kwenguva refu kwechando chekuchengetedza evaporator kunofanira kuderedzwa nguva dzose. Kana isina kuomeswa, chando chechando chiri papombi evaporator chinoungana nekukora. Kana iyo pombi yese yakaputirwa muakajeka ice layer, Ichakanganisa zvakanyanya kutamisa kupisa, zvichiita kuti tembiricha yemumba yekuchengetera iwire pasi peinodiwa chiyero. |
| Pane mafuta efiriji mupombi evaporator | Munguva yefiriji kutenderera, mamwe mafuta efiriji anoramba ari mupombi evaporator. Mushure menguva yakareba yekushandiswa, kana paine akawanda akasara oiri mu evaporator, inozokanganisa zvakanyanya kupisa kwayo. , chiitiko chekushaya kutonhora kunoitika. |
| Iyo firiji system haina kutsetseka | nekuda kwekusacheneswa kwakashata kwefiriji system, mushure menguva yekushandiswa, tsvina zvishoma nezvishoma inoungana musefa, uye mamwe meshes akavharwa, izvo zvinoderedza kuyerera kwefiriji uye zvinokanganisa kutonhora. Muchirongwa, vharafu yekuwedzera uye sefa pachiteshi chekuyamwa che compressor zvakare yakavharwa zvishoma. |
| Gomba revharuvhu yekuwedzera rakaomeswa nechando uye rakavharika | zvikamu zvikuru mufiriji system hazvina kuomeswa zvakanaka, vacuum yehurongwa hwese haina kukwana, uye hunyoro hwefiriji hunopfuura mwero. |
| Kuvharika kwakasviba pasefa skrini yevharuvhu yekuwedzera |
