Freon - shi ne ... zafin jiki na Freon. Freon a firiji

Kowane gidan na da kayan domin samar da kuma ingancinsu na irin wannan abu da aka yi amfani da matsayin freon. Wannan abu ne da aka sani a matsayin kyakkyawan refrigerant amfani da duk fridges haka za ka iya adana abinci da kuma shirya abinci fiye da a yanayi zazzabi. Wannan talifin zai gaya, Freon - shi ne cewa a cikin al'amarin, inda aka yi amfani da, abin da zazzabi shi ne.

Tarihi na samu

Daban-daban kafofin suna da farko kwanakin watan guda biyu kira Freon - 1928 da kuma 1931, shekaru. Daidai da ranar haihuwa na refrigerant 1928 th shekara. A sa'an nan an yi fice sunadarai kamfanin Frigidaire, wanda yake shi ne na biyu daga cikin kamfani General Motors, Thomas Midgley, ya kawo "mu'ujiza abu" da kuma ba shi da sunan "Freon". Mazan injiniyoyi tsunduma a masana'antu samar da wannan iskar gas, sun shiga nadi Freon-12 a matsayin «R» (a translation «Refrigerant» tsaye ga wata refrigerant ko mai sanyaya). Na biyu kwanan tare da zuwan Freon nepravlno daura, saboda tuni a 1930 da m sanadin motsi Chemical Company, wanda yana aiki da aka halitta da za a mayar da hankali a kan samar da wannan samfurin.

Freon - menene wannan?

A cakuda ethane da methane matsayin fluorinated low kwayoyin nauyi hydrocarbon Kalam inda hydrogen atoms iya sauya ta sunadarin flourine, chlorine, bromine. Yadu a yi amfani refrigeration raka'a (refrigerators, freezers, iska conditioners da sauransu. N). Mutane da yawa mamaki, Freon - shi ne mai gas ko wani ruwa? A daidai Amsar ita ce: abu na iya suna da duka jiki jihar.

The fi na kowa iri na Freon

Kimiyya da aka sani fiye da 40 nau'i na abu, mafi yawan abin da aka samu industrially. Freon zazzabi a wadda tana tafasa, kowane jinsin na da:

• R11 - trichlorofluoromethane (t tare da ruwan 23,8 ° C).
• R12 - difluorodichloromethane (tare da mai tsanani t reflux -29,8 ° C).

Yawanci, gida refrigerators aiki a kan freon (Khladone) sa R-22, ga masana'antu da kasuwanci amfani R-13 iri.

Freon - ne mai hadarin gaske abu ga mutane?

Kusan duk iri na kayan da korau tafasar, duk da haka, da shi da ake amfani a cikin sanyaya abubuwa na gida kayan, kamar yadda pusher kashi a cikin gas harsashi, iska fresheners da sauran aerosols.

Mene ne freon a refrigerators?

Modern kwampreso refrigerators aka gabatar a cikin nau'i na kyamarori sanya a cikin evaporator, wanda ya hada da wani refrigerant. Wannan abu a lokacin ruwan da vaporization garwaya da zafi daga jam'iyya da kuma a cikin sandaro aiwatar canja wurin shi zuwa ga yanayi. Saboda wannan iska da aka sanyaya zuwa da ake so zazzabi, da kuma iskar gas ya dawo zuwa ga kwampreso da kuma canza ta Jihar tari a cikin wani ruwa. Freon a cikin firiji ne kawai wannan evaporator. A wasu kalmomin, shi ne wani muhimmin bangaren da tsarin, godiya ga wanda sanyaya ɗakuna, na refrigeration naúrar.

Ta yaya ka sani game da zuba daga Freon daga firiji

A fili yake cewa wannan abu - daya daga cikin babban aka gyara daga cikin dace aiki na kayan aiki. Freon yayyo sakamakon a lalacewar kayan aiki da kuma rashin iyawa don amfani da shi ga sauran dalilai. Mafi na kowa dalilin wannan matsala - da evaporator tube lalacewa ko Manufacturing lahani. Tun da yake wannan ne wani maras tabbas gas, wani odorless, ba shi yiwuwa a gano olfactory rabe.

Duk da haka, akwai wasu alamu da suka nuna da zuba. Freon a cikin firiji ne a karkashin matsin lamba, kuma idan lalace tube evaporator, ya hankali zai fara zuwa fada. Saboda haka, a cikin refrigeration da misãlin jam'iyya iska zazzabi ta fito, da kuma tsarkake sauri fara deteriorate. Wannan shi ne na farko alamar cewa kana bukatar ka duba mutunci da sanyaya tsarin da kayan aiki. Kamar yadda aka ambata a baya, da Freon ba hatsari ga mutum a zazzabi ba fi 250 darajõji, kuma zafi shi zuwa da zazzabi a gida ne ba zai yiwu.

Yadda za a gyara a zuba?

Ciko freon firiji a gida ne ba zai yiwu ba tare da taimakon wani kwararren. Tun lokacin da bukatar musamman kayan aiki da kuma kayan (injin famfo, soldering kuka jin da yawa tare da gauges, wani karfe solder, musamman juyi) domin aikin.
