Supermarket mafiriza anononoka tembiricha inodonha zvikonzero uye mhinduro

1, nekuda kwekuvharwa kwefiriza kana kuvhara kuita kwakashata, zvichikonzera kurasikirwa kukuru kwechando
Chikonzero nei kushata kwekushisa kwekushisa kwekuita imhaka yekuti pombi, bhodhi rekuisa uye kumwe kusungirira dhizaini haina kukwana, insulation uye thermal insulation mhedzisiro haina kunaka, inonyanya dhizaini yekuvharisa dhizaini haina kusarudzwa nemazvo kana kuvaka. yemhando ye insulation yemidziyo haina kunaka. Uye zvakare, mukati mekuvaka, iyo yekudzivirira yekudzivirira hunyoro inodzivirira inogona kukuvadzwa zvichikonzera kuti insulation layer hunyoro, deformation, kana kutoora, kupisa kwayo kwekupisa uye kugona kwekupisa kwekushisa kuderera, kurasikirwa kwechando kunowedzera, kudonha kwekushisa kwakanyanya kuderera. pasi. Chimwe chikonzero chakakosha chekurasikirwa kwechando iko kusaisa chisimbiso kuita kwakashata, kune mhepo inopisa yakawanda kubva pakupinda kwekudonha. Kazhinji, kana tambo yekuisa chisimbiso pamusuwo kana kutonhora kabati kupisa kwekuisa chisimbiso chiitiko, zvinoratidza kuti chisimbiso hachina kusimba. Uye zvakare, kuvhurika nekuvharwa kwegonhi kana vanhu vazhinji pamwe chete muimba yekuchengetera, kuchawedzerawo kurasikirwa kwechando. Inofanira kuedza kudzivirira kuvhura musuwo kudzivirira yakawanda inopisa mweya kupinda. Ehe, mune hesitori kazhinji kana yakawandisa huwandu hwezvinhu, kupisa kwemoto kunowedzera zvakanyanya, kutonhora kusvika kune inodiwa tembiricha zvinotora nguva yakareba.

2, iyo evaporator pamusoro pechando chakanyanya kana guruva rakawandisa, kupisa kwekushisa kunodzikira zvichikonzera kudzikira zvishoma tembiricha ndicho chimwe chikonzero chakakosha chekuti evaporator kupisa kwekutamisa kushanda kwakadzikira, izvo zvinonyanya kukonzerwa neiyo evaporator pamusoro pechando layer. gobvu kana huruva yakawandisa inokonzerwa ne. Nekuda kwekutonhora kwekabati evaporator pamusoro tembiricha kazhinji iri pasi pe 0 ℃, uye hunyoro hwakanyanya, hunyoro hwemumhepo huri nyore kwazvo mu evaporator pamusoro pechando, kana kunyange ice, inokanganisa kupisa kwekushisa kweiyo evaporator. Kuti udzivirire evaporator surface frost layer yakanyanya kukora, zvinodikanwa kuibvisa nguva dzose.
Heano maitiro maviri ari nyore defrosting:

① kumisa muchina kunyungudutsa chando. Kureva, kumisa compressor kumhanya, vhura musuwo, regai tembiricha kukwira, kuti otomatiki yakanyungudutswa chando layer, uye ipapo restart compressor. ② Frost. Mushure mekutamisa zvinhu kubva mufiriji, zvakananga ne tembiricha yepamusoro yepombi yemvura yekutsvaira evaporator chubhu pamusoro, kuitira kuti chando chinyunguduke kana kudonha. Kuwedzera kune gobvu chando chinotungamira kune evaporator kupisa kupisa mhedzisiro haina kunaka, iyo evaporator pamusoro nekuda kwenguva yakareba pasina kuchenesa uye guruva kuunganidzwa kwakanyanyisa, iko kupisa kwayo kutamisa kushanda kuchaderedzwawo zvakanyanya.

3, supermarket freezer evaporator pamberi pemhepo yakawanda kana firiji mafuta, kupisa kwekushisa kunoderera.

Kamwe chete evaporator kupisa kwekutamisa chubhu inonamirwa kune yemukati pamusoro pemafuta akaomeswa nechando, kupisa kwayo kuchinjisa coefficient inodzikiswa, zvakafanana, kana paine mweya wakawanda muhubhu yekupisa yekupisa, evaporator kupisa nzvimbo yekufambisa inoderedzwa, kupisa kwekushisa. kushanda zvakanaka kuchaderedzwawo zvakanyanya, uye chiyero chekudonha kwekushisa chinodzikiswa. Naizvozvo, mukushanda kwezuva nezuva uye kugadzirisa, kunofanirwa kutarisisa kubviswa kwakakodzera kweiyo evaporator kupisa kuchinjisa chubhu pamusoro pemafuta uye kuburitsa mweya muevaporator, kuitira kuvandudza kupisa kwekushisa kweiyo evaporator.

4, throttle valve isina kurongeka kana kuvharika, kuyerera kwefiriji yakakura kwazvo kana kudiki.

Throttle valve isina kudzorwa zvakanaka kana kuvharika, ichakanganisa zvakananga iyo refrigerant inoyerera ichipinda muevaporator. Kana iyo throttle valve yakavhurika yakakura kwazvo, iyo refrigerant inoyerera yakakura, evaporative pressure uye evaporative tembiricha inowedzera, tembiricha inodonha inoderera; panguva imwecheteyo, apo throttle valve yakazaruka idiki kana yakavharwa, kuyerera kwefiriji kunoderedzwawo, simba refiriji regadziriro rinoderedzwawo, kutonhora kweimba yekuchengetedza kunoderedza chiyero chekuderera. Kazhinji nekutarisa kufefeterwa kwemhepo, tembiricha yekubuda uye chando chekusveta pombi kuona kana kuyerera kwefiriji kwakakodzera. Throttle blockage chinhu chakakosha chinokanganisa kuyerera kwefiriji, zvichikonzera throttle blockage ndicho chikonzero chikuru cheaizi plug uye tsvina plug. Ice plug inokonzerwa nekuomeswa kweiyo dryer haina kunaka, iyo firiji ine mvura, inoyerera nepakati pevhavhavhavha, tembiricha inodonha kusvika pazasi 0 ℃, mwando mufiriji muchando uye ichivharira gomba remhepo; tsvina plug inokonzerwa neiyo throttle valve inlet filter mesh pane kuunganidzwa kwenhamba yakawanda yetsvina, refrigerant inoyerera haina kutsetseka, kuumbwa kwekuvhara.
