Freon - ndiko ... Temperature pamusoro Freon. Freon mu firiji

imba imwe neimwe ine midziyo kuti kugadzirwa uye kunyatsoshanda ane pfuma yakadaro rinoshandiswa sezvo freon. fuma iyi inozivikanwa rakaisvonaka refrigerant kushandiswa fridges zvose saka unogona kuchengeta chikafu uye vakagadzirira zvokudya refu kupfuura panguva ambient tembiricha. Nyaya ino ichataura, Freon - ndechokuti panyaya apo rinoshandiswa, chii tembiricha ndizvo.

History yakawanikwa

zvinyorwa zvakasiyana zita rokutanga maviri misi kwetunhu Freon - 1928 uye 1931, makore. Zvakarurama kuti musi kuberekwa refrigerant 1928 fung gore. Yakanga chinoshamisa kemisiti kambani Frigidaire, ndicho chikamu dzesangano General Motors, Thomas Midgley, akauya "chishamiso fuma" uye akamupa zita "Freon". mainjiniya Older vaiita maindasitiri kugadzirwa gasi ichi, vakapinda rokuti Freon-12 ive «R» (mushanduro «Refrigerant» anomirira kuti refrigerant kana unotonhorera). Musi yechipiri veMubatanidzwa Freon nepravlno vachasunga, nekuti atova 1930 zvakasimba Kinetic Chemical Company, ine kushanda wakasikwa kuti pfungwa iri kugadzirwa chigadzirwa ichi.

Freon - chii ichi?

A musanganiswa ethane uye methane sezvo fluorinated pasi samolecular uremu yeHydrocarbon nomukaka apo rehydrogen maatomu anogona akazova fluorine, kuiisa chlorine, bromine. Zvinowanzoshandiswa Refrigeration anokwana zviyero (sefiriji, mafiriza, mhepo conditioners uye zvichingodaro. N). Vakawanda vanonetseka, Freon - ari gasi kana mvura? Mhinduro yakarurama iri: nefuma anogona mumuviri mamiriro.

The emhando dzakawanda zvinowanzovapo Freon

Science anozivikanwa marudzi anopfuura 40 nefuma, akawanda uko vakawana industrially. Freon tembiricha panguva iyo mamota, mumwe mhando ine yayo:

• R11 - trichlorofluoromethane (T pamwe kubika 23,8 ° C).
• R12 - difluorodichloromethane (pamwe nenharo T reflux -29,8 ° C).
• R13 - trifluorochloromethane (pamwe nenharo T reflux -81,5 ° C).
• R14 - tetrafluoromethane (pamwe nenharo T reflux -128 ° C).
• R134A - tetrafluoroethane (achibika nenharo ne t -26,3 ° C).
• R22 - chlorodifluoromethane (pamwe nenharo T reflux -40,8 ° C).
• R600A - isobutane (pamwe nenharo T reflux -11,73 ° C).
• R410A - hloroftorokarbonat (pamwe nenharo T reflux -51,4 ° C).

Kazhinji, musha sefiriji ushande freon (Khladone) mugwaro R-22, nokuti maindasitiri uye vezvokutengeserana kushandiswa R-13 muchiso.

Freon - iri ngozi ane fuma vanhu?

Chinenge mhando dzose nezvinhu taora dzokubikira, zvisinei, uye rinoshandiswa kutonhora zvinhu pamba midziyo yemagetsi, sezvo Hwokutengesa chinhu gasi cartridges, mhepo fresheners nezvimwe aerosols. Naizvozvo kana spraying humburumbira pachayo dzaserera uye Freon anopinda mhepo. Kana refrigerant haisi neshungu kuti 250 madhigirii (nenguva tembiricha ichi, kusunungura zvine chepfu) zviri hakukuvadzi vanhu, havagoni kunzi ozone rukoko. The kuora zvigadzirwa kuiparadza. The chikuru chinokonzera makomba ozone ndiwo kugadzirwa uye kushandiswa Freon rurefu zviri kuiisa chlorine ions uye bromine. Leakage kuti zvinhu mumhuri midziyo yemagetsi uye kunhuwa haagoni kuonekwa nemaziso, mishonga diki pamunhu havana maturo.

Nokuti kupora of ozone rukoko Nyika uye kuderedza kugadzirwa inokuvadza CFCs nyika UN akasaina uye chagamuchirwa zviri Montreal Protocol.

Ndeipi freon mu sefiriji?

Modern compressor sefiriji dzinoturwa muchimiro makamera zvaiiswa mukati evaporator, rinosanganisira refrigerant. Izvi fuma panguva kubika uye vaporization absorbs kupisa yomukati uye condensation kwacho anotamisa kuti zvakatipoteredza. Nokuda mhepo iyi dzaserera kune kutsvakwa tembiricha, uye gasi rinodzokera kuna compressor ochinja ayo ezvinhu aggregation iri mvura. Freon mufiriji inongova evaporator ichi. Mune mamwe manzwi, izvozvo zvinokosha pakuderedza wegadziriro, nemhaka iyo kutonhora Makamuri Refrigeration chikwata.

Unoziva sei pamusoro buri pamusoro Freon kubva firiji

Zviri pachena kuti fuma iyi - mumwe chikuru zvinoriumba zvakakodzera kushanda michina. Freon leakage kunoguma kukuvadza midziyo uye nekusagona kurishandisa kuti zvimwe zvinangwa. The inonyanya Chikonzero dambudziko ichi - kukuvara evaporator chubhu kana mukugadzira kuremara. Sezvo iri yainge gasi, imwe odorless, hazvibviri kuona olfactory receptors.

Zvisinei, pane zvimwe zviratidzo kuti kuziva vhinza. Freon mufiriji zvamutambudza, uye kana ukama chubhu evaporator, zvishoma nezvishoma anotanga kuwa. Somugumisiro, muna Refrigeration uye kuoma nechando kamuri mhepo tembiricha inokwira, akanatsa nokukurumidza akatanga kudzikira. Ichi ndicho chiratidzo chokutanga kuti unofanira kuongorora kuvimbika kutonhora ezvinhu huchashandiswa. Sezvambotaurwa, kune Freon haasi ngozi murume ari tembiricha kwete epamusoro kupfuura 250, uye kudziyisa mumwe tembiricha pamba hazvibviri.

The kupfuura kakawanda nzvimbo refrigerant leakage

Chekutanga - ichi mutopota majoini. Chero pokunamatidza inogona kuumbwa sezvo microcracks nokuda kuramba nokushanda zvokushandisa uye nokuda fekitari muchato. Uyewo yakajairika Freon leakage munzvimbo unobatanidza sepombi evaporator Refrigeration uye gwenya. Kuiswa chisimbiso anogona kuonekwa kubudikidza kudzoka mutsetse, iro rinobatanidza mwoyo mufiriji uye evaporator.

How inogadzirisa vhinza?

Kuzadza freon firiji pamba hazvibviri pasina kubatsirwa nenyanzvi. Sezvo vanoda inokosha michina uye zvinhu (vacuum pombi, pokunamatidza burner dispenser zhinji pamwe gauges, resimbi solder, inokosha nekubudisa) nokuti basa. Nokuti kuziva miedzo leakage pakati sepombi vachishandisa zano rinokosha kuti chakafanana simbi detector. Mushure tenzi kuziva zvinokuvadza uye mugove chisimbiso, kubvisa leakage, kuti Vacuum Pombi pumped gasi vasara uye akapfeka zvakare. Zvekupfakira kunoitika nomukombiyuta chibharuma chokuita gasi kuti kamwene iri casing pakati mufiriji compressor, kuburikidza rirambe richibvira chubhu kubatana chakaputirwa kiyi.

Zvadaro, mumwe freon firiji zvakare anotanga kutenderedza zvakanaka uye tembiricha napamakamuri yakaiswa maererano nemitemo kuti Refrigeration mano.
