TheMadaidaitan firjikuma firij a kwance a kasuwa suna amfani da sanyaya iska, refrigeration, da dai sauransu, amma duk nau'ikan refrigerant ne R600A da R134A. Tabbas, "mai kara kuzari" a nan yana nufin canja wurin makamashi, wato, vaporization da condensation don cimma canjin zafi. Ga mutane na yau da kullun, kawai muna buƙatar fahimtar cewa yana da muhimmin sashi na firiji.
Don sauƙaƙe muku fahimta, ainihin ƙa'idar refrigeration ta dogara da juzu'in Carnot ta hanyar matakai huɗu masu mahimmanci:
(1) Matsi (high zafin jiki da high matsa lamba gas)
Compressor yana matsawa ƙananan zafin jiki da ƙananan iskar gas mai sanyi a cikin babban zafin jiki da iskar gas, yana sa zafinsa ya tashi sosai (misali daga -20 ° C zuwa 100 ° C).
(2) Condensation (zafi ya zama ruwa)
Babban zafin jiki da iskar gas mai ƙarfi suna shiga cikin na'urar, yana fitar da zafi ta cikin fan mai sanyaya, kuma ya juya zuwa yanayin zafi na yau da kullun da ruwa mai ƙarfi bayan sanyaya.
(3) Fadada (raguwar matsa lamba endothermic)
Bayan ruwa mai matsananciyar matsa lamba ya wuce ta bawul ɗin faɗaɗawa, matsa lamba yana faɗuwa da ƙarfi, wani ɓangare na tururi da ɗaukar zafi a kusa da mai fitar da ruwa, yana sa cikin firiji ya huce.
(4) Evaporation (ƙananan zafin jiki da ƙarancin iskar gas)
Ruwan mai sanyaya a ƙananan zafin jiki da matsa lamba gaba ɗaya yana yin tururi a cikin evaporator, yana ɗaukar zafi a cikin firiji, sa'an nan kuma komawa zuwa compressor don kammala zagayowar.
A wannan lokaci, muhimmiyar rawa na refrigerant yana nunawa a cikin canjin yanayin zafi da haɓakawa, kuma tsarin ƙaddamar da zafi na vaporization zai kwantar da firiji.
Lura:Ana sake sarrafa na'urar a cikin rufaffiyar tsarin kuma ana amfani dashi akai-akai ba tare da an sha ba. Its jiki Properties (misali low tafasasshen batu, high latent zafi) ƙayyade sanyaya yadda ya dace.
Anan ina buƙatar in bayyana muku cewa masu amfani za su iya rikitar da manufar "catalyst" da "matsakaici". Refrigerant ba sa shiga cikin halayen sinadarai, amma suna canja wurin makamashi ta hanyar sauye-sauyen lokaci na jiki, amma aikinsu kai tsaye yana shafar tasirin sanyaya (kamar inganci, zafin jiki), kamar mahimmancin abubuwan da ke haifar da halayen sinadarai, amma hanyoyin biyu sun bambanta sosai.
Siffofin:
(1) Yana da sauƙi don vaporize da sha zafi a dakin da zafin jiki (misali R600a tafasar batu - 11.7 ° C), yana da kwanciyar hankali na sinadaran, kuma ba sauki bazuwa ko lalata kayan aiki.
(2) Abokan muhali: Rage lalacewa ga Layer na ozone (misali R134a ya maye gurbin R12).
Refrigerant sune ainihin matsakaicin firiji na kasuwanci. Suna canja wurin zafi ta hanyar canjin lokaci, kama da "masu ɗaukar zafi", waɗanda ke sakin zafi a cikin firiji zuwa waje ta hanyar kewayawa, don haka kiyaye yanayin ƙarancin zafi.
