Freon - kuyinto ... lokushisa ka Freon. Freon in esiqandisini

Umuzi ngamunye has Imishini zokukhiqiza kahle into enjalo isetshenziswa njengoba freon. Le into is njengenhlangano refrigerant kakhulu asetshenziswa kuzozonke fridges ngakho ungakwazi ukugcina ukudla ukudla ngomumo isikhathi eside kunaleso at lokushisa kuma ezaziwayo. Lesi sihloko uzokutshela, Freon - wukuthi kule ndaba lapho esetshenziswa, lokho lokushisa ngayo.

Umlando yokutholakala

emithonjeni ehlukene igama lokuqala izinsuku ezimbili zamagama Freon - 1928 no-1931, iminyaka. Lungisa ukuthi usuku lokuzalwa refrigerant NGONYAKA KA-1928-th. Yingaleso sikhathi-ke inkampani wemithi oluvelele Frigidaire, okuyinto ephethwe Nhlangano General Motors Thomas Midgley, baletha "isimangaliso izidakamizwa" futhi wamnika igama "Freon". onjiniyela Okudala wahlanganyela ukukhiqizwa yezimboni le gesi, Ufake isiqu Freon-12 sokuba «R» (ukuhumusha «Refrigerant» imele ibe refrigerant noma cooler). Usuku lwesibili nge obhekwe Freon bophezela nepravlno kudala njengoba 1930, le nkampani Kinetic Chemical Company, okuyinto has ukusebenza sidaliwe ukuba egxile ukwenziwa kwalo mkhiqizo.

Freon - Iyini?

A ingxube ethane ne-methane njengoba fluorinated ongaphakeme isisindo yamangqamuzana hydrocarbon nemikhiqizo lapho kungenzeka ama-athomu ye-hydrogen Ikhutjhwe yi sasekhaya, chlorine, uxhumano lokudlulisa. Kabanzi ifriji amayunithi (amafriji, nokuqondisayo, umoya isimo nokunye. N). Yingakho abaningi, Freon - iyinhlangano igesi noma uketshezi? Impendulo ekungilo: ketshezi ungaba kokubili isimo ngokomzimba.

Izinhlobo ezivame kakhulu Freon

Isayensi eyaziwa ezingaphezu kuka-40 izinhlobo ketshezi, iningi okuyinto etholakala ngokuphakeme ezimbonini. Freon lokushisa lapho ke amathumba, ngalunye oluphilayo zakwazi unendlela yawo:

• R11 - trichlorofluoromethane (t nge abilayo 23,8 ° C).
• R12 - difluorodichloromethane (nge evuthayo t Reflux -29,8 ° C).
• R13 - trifluorochloromethane (nge evuthayo t Reflux -81,5 ° C).
• R14 - tetrafluoromethane (nge evuthayo t Reflux -128 ° C).
• R134A - tetrafluoroethane (abilayo evuthayo ne-t -26,3 ° C).
• R22 - chlorodifluoromethane (abilayo ukufuthelana ne-t -40,8 ° C).
• R600A - isobutane (nge evuthayo t Reflux -11,73 ° C).
• R410A - hloroftorokarbonat (nge evuthayo t Reflux -51,4 ° C).

Ngokuvamile, ekhaya amafriji bahlinza freon (Khladone) ebangeni R-22, ukusetshenziswa ezimbonini kanye commercial R-13 brand.

Freon - kuyinto into eyingozi ngesintu?

Cishe zonke izinhlobo izinto abe negative abilayo, Nokho, futhi isetshenziswa izakhi Ukupholisa ekhaya Imishini, njengoba element pusher ku igesi cartridges, iziqeda kanye nezinye aerosols. Ngakho-ke lapho sishaye uMbhalo ngokwayo selehlile futhi Freon ingena emoyeni. Uma refrigerant akuyona sishisiswe 250 degrees (ngalesi lokushisa, ukukhulula ezinobuthi) kuba ingozi kubantu, ngeke kusho ukuthi ungqimba lwe-ozone. Imikhiqizo kwamazinyo kubuqede. Isizathu esikhulu izimbobo lwe-ozone zokukhiqiza nokusebenzisa Freon nge wokuqukethwe lelisetulu chlorine ion futhi uxhumano lokudlulisa. Ukuvuza izidakamizwa e zasendlini kanye nephunga ayikwazi ukutholwa zibukeke, ngemithamo emincane umuntu ngamunye azinamphumela.

Ukuze yokutakula ka ungqimba lwe-ozone Zomhlaba nokwehlisa ukukhiqizwa CFCs eziyingozi amazwe UN ngemvume futhi samukelwa Montreal Protocol.

Uyini freon e amafriji?

Modern compressor amafriji ethulwa ngesimo amakhamera ibekwe ngaphakathi evaporator, okubandakanya refrigerant. Le into ngesikhathi abilayo futhi vaporization ubamba ukushisa esuka egumbini nasesikhathini Ukudluliselwa inqubo ukufingqa yona imvelo. Ngenxa yalokhu emoyeni selehlile izinga lokushisa oyifunayo, kanti igesi ubuyela compressor futhi eshintsha isimo yayo wokuhlanganisa in uketshezi. Freon esiqandisini lokhu nje evaporator. Ngamanye amazwi, kuba ebalulekile ohlelweni, sibonga ngalo emakamelweni ukupholisa we ifriji iyunithi.

Wazi kanjani mayelana ukuvuza of Freon kusukela efrijini

Kuyacaca ukuthi lokhu izidakamizwa - kwenye yezingxenye eyinhloko ekusebenzeni kahle imishini. Imiphumela Freon ukuvuza e umonakalo empahleni nokungakwazi ukuyisebenzisela ezinye izinjongo. Isizathu ezijwayeleke kakhulu ngale nkinga - umonakalo evaporator tube noma ukukhubazeka yokukhiqiza. Njengoba lena igesi oluyingozi, i ayinaphunga, akunakwenzeka ukuthola la mangqamuzana olfactory.

Nokho, zikhona ezinye zezimpawu ezikhombisa ukuthi ukuhlonza ukuvuza. Freon esiqandisini ungaphansi kokucindezeleka, futhi lapho lilimele tube evaporator, kancane kancane iqala ukuna. Ngenxa yalokho, esikhathini ifriji umnkantsha lokushisa ekamelweni air liyaphuma, kwemijondolo ngokushesha aqala ukuwohloka. Yilesi isibonakaliso wokuqala ukuthi udinga ukuhlola ubuqotho ohlelweni ukupholisa wezinsimbi zomculo. Njengoba kushiwo ngaphambili, Freon akuyona yingozi indoda ezingeni lokushisa hhayi ephakeme kuka-250 degrees, futhi shisisa ke lokushisa ekhaya akunakwenzeka.

Izindawo njalo iningi refrigerant ukuvuza

Okokuqala - lokhu ipayipi amalunga omzimba. Kunoma nokunamathisela ngomthofu zingase zimiswe njengoba micro-imifantu ngenxa operation eside imishini futhi ngenxa umshado endaweni yokukhanda. Kuphinda Freon ukuvuza ezindaweni yokuxhuma amashubhu evaporator ifriji efrijini. Ukubekwa uphawu kungatholakala line ukubuya, okuyinto uxhuma inhliziyo esiqandisini futhi evaporator.

Indlela ukulungisa avuzayo?

Ukugcwalisa freon esiqandisini ekhaya akunakwenzeka ngaphandle kosizo okhokhelwayo. Njengoba kudingeka imishini ekhethekile futhi izinto (cleaner futha, nokunamathisela ngomthofu sikaphalafini dispenser ezininginingi nge Izikali, solder metal, ecucuza ekhethekile) lo msebenzi. Ngoba ukuthola ukuvuza amashubhu usebenzisa idivayisi ekhethekile ofana metal detector. Ngemva master ukuhlonza yokulimala futhi ingxenye evaliwe, ekuqedeni ukuvuza, futha cleaner akhishwa igesi ezisele futhi futhi bagqoke ngendlela ehloniphekile. Ukugcwalisa kwenzeka nge uxhumano ibhaluni ne gas umlomo wombhobho esisogwini bezinhlamvu we compressor esiqandisini, ngokusebenzisa ukuxhumana capillary tube ivaliwe ukhiye.

Ngemva kwalokho, isiqandisi freon futhi iqala aluka kahle futhi izinga lokushisa emakamelweni isethwe ngokuhambisana namazinga amadivayisi ifriji.
