Tembiricha yekubuda kwecompressor mufiriji inoreva vharuvhu yekubuda kwemhepo patembiricha yekufiriji, kuitira kuve nechokwadi chekuti compressor inoshanda zvakachengeteka, zvinodiwa zvetembiricha yekubuda kwemhepo mumudziyo weR12 hazvifanirwe kudarika 130℃, R22 uye masisitimu eammonia haafanire kudarika 50℃. Kupisa kweutsi kwakakwira zvakanyanya, izvo zvinoita kuti oiri yekuzora ideredze viscosity nekuda kwekuwedzera kwekupisa, uye kuita kuti mafuta aite seasina kunaka, izvo zvinoita kuti zvikamu zvinomhanya zvikanganiswe. Kana tembiricha yeutsi yakwira pedyo nenzvimbo yekupenya kwemafuta, hazvisi nyore kuva nengozi, uye tembiricha yeutsi yakakwira zvakanyanya kupfuura tembiricha yekudzika kwemvura.
Kupisa kwekabati rinotonhora kwakakwira muzviitiko zviviri: Chekutanga, fluorine inobuda mufiriji uye hapana kabati rinotonhora refiriji rave richishanda, asi tembiricha iri mukati mekabati haigone kuderedzwa. Nguva yakareba, kurasikirwa kwechikafu mukati mekabati kwakakomba, ndapota gadzirisai panguva chaiyo. Sezvakajairika, haisi firiji itsva chete, asi kazhinji mukamuri rinotonhora hafu yechando kuti ikupei kunzwa uku kunogara kuchinonoka. Imwe hafu haina chando uye yakakora parutivi rwechando. Firiji haina chando kwenguva yakareba. Panguva ino, panogona kunge paine mapoinzi mashoma emvura anoratidzwa, tembiricha iri mukati mekabati yakakwira.
Firiza yakadaro inowanzova yakaoma kugadzirisa. Zvinonetsa kuwana mvura inobuda kwenguva yakareba mushure mekugadzirisa nekuti zvinonetsa kuwana mvura inobuda. Chikonzero chechipiri chekupisa kwakanyanya ichando che evaporator, mamiriro aya anonyanya kuve mafiririza anotonhorerwa nemhepo, rudzi urwu rwefiriji runoda evaporator, kana kusiri kurasikirwa nechando mu evaporator iyi, ichavhara nzira yemhepo. Kutonhora hakuzobudiswi uye firiza haigone kutonhodzwa. Dambudziko iri rinogona kunge riri nekuda kwedambudziko re defrost system kana kuti defrost timer haina kunaka kana kuti heating tube yakakuvara.
1. Compressor haizotanga
Kana mufiriji musina simba uye mwenje wemukati uchigona kuvheneka, unogona kuvhara gonhi refiriji. Kana firiji ikazivisa kuti kune simba, kana mwenje usingabatidzi, tarisa kana simba guru riripo wobva waona kuti fuse yefiriji haisiriyo firiji yese. Pane dambudziko here nekugunzva kwethermostat?
2. Compressor inogona kutsva, mota coil yatsva, uye starter inogona kuongororwa. Kana chidziviriro chekupisa zvakanyanya chichishanda, unofanira kumirira kwenguva yakati kuti tembiricha yecompressor itange kudzikira.
3. Dambudziko rinoitika nekuti thermostat haigone kudzoserwa patsva, nekuti ma contacts acho akabatana uye haagone kuparadzaniswa.
3. Chando chiri mufiriji chakanyanya kukora uye kuramba kupisa kwakanyanya, izvo zvinokanganisa kufambiswa kwemhepo inotonhora.
4, firiji haina kuiswa nemazvo kana kuti kuunganidzwa kwedota re condenser kwakanyanyisa kukobvu, nokudaro zvichikanganisa kupera kwekupisa kwe condenser.
5, kuchaja kwesystem yekutonhodza kwakawandisa, mutoro wekushanda kwecompressor wakanyanya, condenser inopisa kumusoro, divi rezasi riri pedyo netembiricha yemukamuri. Chaja yefriji yakawandisa inokonzerwa ne evaporator haigone kupwanywa zvizere, zvichikonzera kudzikira kwesimba rekutonhodza re evaporator, kana process orifice yakabatana ne pressure table check, kudzvanywa kwakaderera kunogona kuwanikwa pamusoro peyakajairika kukosha.
Kupisa kwekukweva kwecompressor yefiriji ndiko kupisa kwemuchina wefriji pavharuvhu yekufemera. Kuti compressor ishande zvakanaka, kudzivirira kuitika kwe liquid shock cylinder. Kupisa kwekukweva kunofanira kunge kwakakwira zvishoma pane kupisa kwekubuda kwemvura, zvinoreva kuti gasi refiriji rinova gasi rinopisa zvakanyanya, rine kupisa kwakanyanya. Kazhinji, hapana gasi-liquid subcooler.
MuFreon system inotonhorera, tembiricha yegesi inosveta inofanira kuva 5℃tembiricha yekupisa kwemvura yakakwira kupfuura tembiricha yemhepo inobuda, uye dhigirii rekupisa kwemhepo rinokweva mweya rakakodzera. Pamudziyo wekutonhodza weammonia, dhigirii rekupisa kwemhepo rinokweva mweya rinowanzova 5~10℃, dhigirii rekupisa zvakanyanya kana kuti diki rinofanira kudzivirirwa, kana dhigirii rekupisa zvakanyanya, zvichaita kuti kugona kwefiriji kudzikire, tembiricha yekubuda kwemhepo ikwire, kushandiswa kwesimba kuwedzere, kana dhigirii rekupisa zvakanyanya kudiki, zviri nyore kugadzira chinhu che liquid strike cylinder.
