Iyohita yekunyungudutsachinhu chakakosha pakunyungudutsa kwefiriji. Chidziyo chefiriji chinobatsira kunyungudutsa chando chinoungana pamakoiri e evaporator ari mufiriji. Pasina chidziyo che defrost, kuungana kwechando kunogona kukanganisa mashandiro enguva dzose efiriji, zvichikonzera kuora kwechikafu uye kugadzirisa kunodhura.
Nheyo yekushanda kwehita yekunyungudutsa firijiinogadzira kupisa kuburikidza nezvinhu zvinodzivirira kuti chando chinyunguduke. Kazhinji kacho chinowanikwa zvakananga pasi pe evaporator coil, kuitira kuti kupisa kunenge kwashandiswa kunyungudutse chando zvakananga uye kubvumira mvura kuyerera ichipinda mupani yekudonhedza mvura.
Kune mhando mbiri dzakajairika dzenyungudutsa machubhu ehitaMumafiriji: maheater anopenya uye maheater anopenya. Maheater anopenya isimbi dzakati sandara dzinoiswa mufiriji, kazhinji dziri pasi. Kune rumwe rutivi, maheater anopenya ane macoil akatenderedzwa ne evaporator coils uye akabatana zvakananga ne defrost thermostat.
Thermostat inonyungudutsa inoshanda pamwe chete nechinhu chinonyungudutsa chinopisa kuti idzore tembiricha iri mukati mefiriji. Kana tembiricha iri mukati mefiriji yadzikira pasi peimwe nhanho, iyo thermostat inonyungudutsa inotanga kunyungudutsa chinopisa uye inoita kuti chinopisa chinyunguduke. Zvadaro, chando chinoumbwa pamakoiri e evaporator chinotanga kunyunguduka uye mvura inoyerera ichipinda mupani yekudonhedza mvura.
Zvakakosha kuziva kuti haasi mafiriji ese ane maheaters ekunyungudutsa. Semuenzaniso, mafiriji madiki haawanzo kuva nechinhu ichi. Pamusoro pezvo, mamwe mamodheru matsva anoshandisa dzimwe nzira dzekunyungudutsa, dzakadai se adaptive defrost systems, dzinoshanda nekutarisa kuungana kwechando pama evaporator coils uye kunyungudutsa zvinoenderana.
Mukupedzisa,nyungudutsa maheaterchinhu chakakosha pakushanda zvakanaka kwefiriji.hita yekunyungudutsa firijiBasa rayo nderekunyungudutsa chando chakaunganidzwa pama evaporator coils, kudzivirira chikafu kuti chisaora, uye kudzivirira kugadzirisa kunodhura. Kunyangwe mafiriji ese asinawo, mazhinji anawo. Pasina iwo, kushanda kwefiriji kwakajairika kuri panjodzi. Saka, kana ukaona chero matambudziko ne defrost cycle, zvakakosha kuti nyanzvi iongorore kuti ive nechokwadi chekuti defrost heater yako iri kushanda nemazvo.
Zvikanganiso Zvakajairika
— Chubhu yekudziyisa yakakuvara:Nekuda kwekushandisa kwenguva refu kana matambudziko emhando,nyungudutsa chubhu yekudziyisainogona kupwanyika kana kutsva, zvichikonzera kusakwanisa kunyungudika.
— Dambudziko rekubatanidza waya:Kana waya yekubatanidza yechubhu yekudziyisa inonyungudutsa isina kusimba kana kuti yakatyoka, ichaita kuti chubhu yekudziyisa itadze kushanda nemazvo.
— Kukundikana kwe sensor yekunyungudutsa:Kana sensor yekunyungudutsa mvura ikakuvara, zvinogona kukonzera kuti chubhu yekudziya itadze kutanga kana kushanda kwenguva yakareba, zvichikanganisa mashandiro enguva dzose efiriji.
Kugadzirisa uye Kuongorora
— Kuongorora Nguva Dzose:Tarisa chitarisiko chenyungudutsa machubhu ehitachero kukuvara kana ngura.
— Edza kuramba:Shandisa multimeter kuyera resistance ye heating tube kuti uone kana iri kushanda nemazvo (resistance value inowanzova pakati pemakumi e ohms nemazana e ohms).
— Bvisa pombi yekudhonza mvura:Iva nechokwadi chekuti mvura inonyungudika inogona kuburitswa zvakanaka kudzivirira kuvharika.
Kugadziriswa nguva dzose uye kutsiva zvakakuvara nenguvanyungudutsa machubhu ekudziyisainogona kuona kuti firiji inoshanda zvakanaka uye kuti inokwanisa kushandisa simba rayo zvakanaka uye kuwedzera nguva yayo yekushanda. Kana paine matambudziko ekunyungudutsa, zvinokurudzirwa kuti ubate vashandi vekugadzirisa vane hunyanzvi kuti vaongorore uye vagadzirise.
