Mene ne babban manufa da na kowa firiji da kuma a refrigeration tsarin?

A zamani duniya wuya su yi tunanin ba tare da nasarorin da kimiyya da fasaha ci gaban wayewar. Godiya ga binciken kimiyya mutane sanya samuwa daban-daban iri makamashi da cewa amfana bil'adama a yau. Daya daga cikin wadannan cimma gaci ya sabuwar dabara na refrigeration naúrar a 1910, Faransa likita Marcel Odifrenom.

Ka'idar aiki na firiji dangane da zahirin al'amari na sandaro danshin, wanda aka bayyana kamar haka: zãfi famfo refrigeration tsarin Canza wurin zafi da makamashi daga aiki jam'iyya zuwa waje, inda ta cools da aka dissipated a cikin muhalli. A sanyaya gas da abubuwa a matsayin freon, sulfur hexafluoride, ammonia, ko daukawa fitar da kishiya tsari, a cikin abin da sanyi da aka samar.

Don cimma wani babban sanyaya yi ake bukata babban yankin na dumama da kuma sanyaya zafin rana Exchanger su iya haifar da babban matsin. Modern refrigeration tsarin shi ne, ba ko da yaushe m, saboda haka a nan domin a cimma bukata matsa lamba amfani compressors cewa damfara da kuma tsotso refrigerant tururi, game da shi kara ba kawai da matsa lamba amma kuma da yawan zafin jiki na coolant. Saboda haka, ka'idar aiki na refrigeration tsarin dogara ne a kan ka'idojin kimiyyar lissafi.

Refrigeration compressors ne na wadannan iri:

- Dunƙule.

- fistan.

- centrifugal irin.

A karshen su ne mafi tasiri da kuma yadu a yi amfani da zamani refrigeration tsarin ga masana'antu amfani. Bugu da kari, a cikin wani firiji da kuma injin daskarewa dole ya hada da wani capacitor wanda aka yi nufi ga maida da tururi a cikin ruwa saboda canje-canje a cikin yanayi zazzabi.

A general, wani firiji aiki manufa ba kawai amfani da su janye refrigeration domin dalilai daban-daban, amma daskarewa tsarin, tun da daidaitawa matsa lamba a cikin tsarin iya samu da ake so zafin jiki cikin masallãci yanayi. Lokacin da kwampreso wuce refrigerant karkashin babban matsin ta musamman orifice da kuma shiga cikin vaporization ɗaki inda sakamakon kaifi rage m nan take ya canza kama zuwa tururi matsa lamba. A wannan jiki sabon abu daga cikin refrigerant saboda da kaddarorin yana daukan zafi daga evaporator ganuwar, sakamakon shi a hankali a hankali sanyaya na ciki jam'iyya na refrigeration naúrar.

Ka'idar aiki na firiji An yi amfani da fiye da shekaru 100, kuma a kowace shekara akwai karin sabon da kuma inganta kafuwa. Daya daga cikin latest ƙirƙirãwa a cikin wannan filin ya kasance fitowan thermoelectric refrigeration raka'a cewa amfani da Peltier manufa. A sakamakon dogara ne a kan abin da ya faru na zazzabi bambanci na matsakaici lokacin da wani halin yanzu gudana, inda yana yiwuwa a cimma rage ciki zafin jiki na refrigeration yanayi sarari. Duk da cewa da koya dogon da suka wuce gano dukiya na da lantarki, har kwanan nan tartsatsi irin sanyi Stores bai sami. Yawancin su suna amfani da su cikin mota refrigerators, Coolers da kuma ruwan sha mai sanyaya jakar, amma saboda tsadar kudin da thermoelectric sanyaya abubuwa nufi har kwanan nan ba a isasshe watsa.

Modern mataki firiji manufa zai ba da damar da aikace-aikace na masana'antu refrigerating da misãlin raka'a a masana'antun sarrafa kayayyakin abinci, kazalika da sanyi ajiya makaman da sito kayayyakin. Yana da wuya a overestimate da muhimmancin samu na biyu ka'idar Thermodynamics, saboda ba tare da shi ba zai yiwu ba ga aiwatar da dukan ayyukan na zamani abinci aiki shuke-shuke. Saboda haka, ka'idar aiki na firiji yau aza harsashin ginin zamani sanyaya tsarin na biyu masana'antu da kuma m dalilai.
