Ka'idar evaporator firiji

Ka'idar aiki na evaporator ta dogara ne akan ka'idar jiki na canjin lokaci yana ɗaukar zafi. Yana biye da matakai huɗu na gabaɗayan zagayowar firji:
Mataki 1: Rage matsi
Matsakaicin matsa lamba da na al'ada-zazzabi na ruwa refrigerant daga condenser gudana ta cikin capillary tube (ko fadada bawul) ga throttling, haifar da wani kwatsam digo a matsa lamba da kuma canza a cikin low-matsa lamba da low-zazzabi ruwa (dauke da karamin adadin gas), shirya domin evaporation.
Mataki 2: Haɓakawa da ɗaukar zafi
Waɗannan firijiyoyin ruwa masu ƙarancin zafin jiki da ƙarancin matsa lamba suna shiga cikin coil na evaporator. Saboda ƙarancin matsa lamba, wurin tafasa na refrigerant ya zama ƙasa da ƙasa sosai (mafi ƙarancin zafin jiki na cikin firiji). Saboda haka, da sauri yana ɗaukar zafi daga iskar da ke gudana a saman farfajiyar mai fitar da ruwa, yana tafasa kuma yana ƙafewa cikin ƙarancin matsi da ƙarancin zafin jiki.
Wannan tsarin canjin lokaci na "ruwa → iskar gas" yana ɗaukar zafi mai yawa (zafin latent na vaporization), wanda shine ainihin dalilin sanyi.
Mataki na 3: Ci gaba da sha zafi
Na'urar sanyaya gas tana ci gaba da gudana a cikin bututun evaporator kuma yana ƙara ɗaukar zafi, yana haifar da ɗan ƙara yawan zafin jiki (zazzaɓi), yana tabbatar da cewa refrigerant ɗin ruwa ya ƙafe gaba ɗaya tare da guje wa tasirin ruwa akan kwampreso.
Mataki na 4: Komawa
A ƙarshe, ƙananan matsi da ƙananan zafin jiki na gaseous refrigerant a ƙarshen evaporator an dawo da shi ta hanyar compressor kuma ya shiga zagaye na gaba.
Za'a iya taƙaita dukkanin tsari a matsayin tsari mai sauƙi: Refrigerant evaporation (canjin lokaci) → Shayar da zafi mai yawa → Yanayin zafin jiki na cikin firiji ya sauke.
Bambanci tsakanin masu sanyaya kai tsaye da masu sanyaya iska
Halaye: Firinji mai sanyaya kai tsaye Firinji mai sanyaya iska
Wurin evaporator: Ganuwa kai tsaye (a kan bangon ciki na injin daskarewa) Boye (a bayan ɓangaren baya ko tsakanin yadudduka)
Hanyar musayar zafi: Ƙunƙarar yanayi: iska tana tuntuɓar bangon sanyi kuma a zahiri tana nutsewa Tilastawa convection: Ana hura iska ta cikin injin da aka ƙera ta fan.
Yanayin sanyi: Defrosting da hannunka (sanyi yana taruwa akan bangon ciki da ake iya gani) Rushewar sanyi ta atomatik (mai zafi yana cire dusar ƙanƙara lokaci-lokaci, kuma ruwan yana zubar)
Daidaita yanayin zafi: Mara kyau, tare da bambance-bambancen zafin jiki Mafi kyau, fan yana sa yanayin yanayin sanyi ya zama iri ɗaya
