Mahita ekunyungudutsazvinhu zvakakosha mumafiriji, kunyanya mumafiriji nemafiriji, uko basa razvo riri rekudzivirira kutonhora kwechando pamakoiri e evaporator. Kuunganidzwa kwechando kunogona kuderedza kushanda zvakanaka kwemasystem aya, zvichizopedzisira zvakanganisa kugona kwawo kutonhora.
Iyochubhu yekudziya inonyungudutsa firijichikamu chakakosha chegadziriro yekutonhodza firiji, iyo inonyanya kushandiswa kunyungudutsa chando chakaunganidzwa pa evaporator muchikamu chechando chega chega kuti ive nechokwadi chekuti firiji inoshanda zvakanaka.
Basa rekudzikisa hita:
kunyungudutsa: Panguva yekushanda kwefiriji, pamusoro pemuchina we evaporator pachatonhora, uye chando chakakora chichakanganisa mhedzisiro yekutonhora.chubhu yekudzikisa chandoinonyungudutsa chando nekudziisa, kuitira kuti evaporator ikwanise kudzokera pakushanda kwayo kwakajairika.
Frost inogadzirwa otomatiki: Mafiriji emazuva ano anowanzo kuve nehurongwa hwefrost inogadzirwa otomatiki umonyungudutsa chubhu yekudziyisainotanga panguva yakatarwa kana pasi pemamiriro akatarwa uye inodzima yega mushure mekunyungudutsa.
Pfungwa inoshanda yeheater yekunyungudutsa ndeyekudziisa evaporator coil panguva dzakatarwa kuti inyungudise chando chakawanda. Heaters dzinonyungudutsa dzinowanzo shandiswa dzinowira mumhando mbiri: rudzi rwekudziyisa rwemagetsi uye rudzi rwekudziyisa negasi rinopisa.
Mahita emagetsi anonyungudutsa chandozvinowanzoiswa mumafiriji epamba nemafiriji. Mahita aya akagadzirwa nezvinhu zvinodzivirira zvakaita se nickel-chromium alloys, izvo zvinodzivirira zvakanyanya uye zvinogona kuburitsa kupisa kana magetsi achipinda nepakati pawo. Anoiswa neunyanzvi pedyo nema evaporator coils kana kuti akaiswa zvakananga pama coils.
Kana firiji ichishanda panguva yekutonhora, ma evaporator coils anotora kupisa kubva mukati, zvichiita kuti hunyoro mumhepo huite chando uye huome pa ma coils. Nekufamba kwenguva, izvi zvinoumba chando. Kudzivirira kuungana kwechando zvakanyanya, defrost timer kana control board inotanga defrost cycle nguva nenguva, kazhinji maawa matanhatu kusvika gumi nemaviri ega ega, zvichienderana nemuenzaniso wefiriji.
Kana kutenderera kwekunyungudutsa kwatanga, sisitimu yekudzora ichacheka compressor uye ichatanga kushandahita yekunyungudutsa. Mhepo inopfuura nemuchitofu, ichigadzira kupisa kunodziisa macoil evaporator. Sezvo tembiricha yecoil ichikwira, chando chinoungana chinotanga kunyunguduka uye chinoshanduka kuita madonhwe emvura.
Kuti idzivirire kukuvara kwesystem uye ive nechokwadi chekuti inonyungudika zvakanaka, thermostat inonyungudika inotarisa tembiricha ye evaporator coil. Kana tembiricha yasvika padanho rakati, zvichiratidza kuti chando chanyungudika zvizere, thermostat inotumira chiratidzo kune control system kuti imise kutenderera kwekunyungudika.
Mvura inoumbwa kubva muchando chinonyunguduka inoyerera ichidzika ne evaporator coil ichienda ku drip pan iri pasi pemudziyo. Ikoko, inowanzo pwanyika nekuda kwekupisa kunogadzirwa ne compressor panguva yekutonhora kwakajairika.
Kune rumwe rutivi, masisitimu ekunyungudutsa gasi rinopisa anonyanya kuwanikwa mumidziyo mikuru yekunyungudutsa yekutengeserana. Mumasisitimu aya, pachinzvimbo chekushandisa maheater emagetsi, firiji pachayo inoshandiswa kunyungudutsa macoil. Munguva yekunyungudutsa, sisitimu yekunyungudutsa inochinja mafambiro ayo ekushanda.
Vharuvhu inopinza zvakananga gasi rinodziya uye rinopisa zvakanyanya rinobuda mucompressor richienda mu evaporator coil. Gasi rinopisa parinoyerera nemu coil, rinoendesa kupisa kune chando, zvichiita kuti rinyunguduke. Mvura yakanyunguduka inobviswa. Mushure mekunge defrosting cycle yapera, vharuvhu inodzosera refrigerant ku cooling circuit yayo yenguva dzose.
Ingava sisitimu yemagetsi yekunyungudutsa kana sisitimu yekupisa gasi, chinangwa chavo ndechekubvisa chando chiri pa evaporator coil, asi vanoshandisa nzira dzakasiyana dzekunyungudutsa.
Kugadziriswa nguva dzose uye kushanda kwakajairika kwenyungudutsa machubhu ehitazvakakosha pakushanda zvakanaka kwesystem yekutonhodza. Kusashanda zvakanaka kweheater kunogona kukonzera kuungana kwechando zvakanyanya, kudzikira kwekushanda zvakanaka kwefiriji, uye kukuvara kwemidziyo.
Maheater anonyungudutsa anoita basa guru mukuchengetedza mashandiro akanaka efriji nekudzivirira chando kuti chisaumbe pamacoil evaporator. Ingava kuburikidza nekupisa kunodzivirira kupisa kana kupisa negasi rinopisa, maheater aya anoita kuti macoil asaome, zvichibvumira system kushanda zvakanaka uye kuchengetedza tembiricha inodiwa mukati memudziyo.
