Freon - waa ... Heerkulka of Freon. Freon qaboojiyaha

guriga kasta wuxuu leeyahay qalabka loogu talagalay soo-saarka iyo hufnaanta walax noocan oo kale ah waxaa loo isticmaalaa sida freon. walax Tan waxaa loo yaqaan refrigerant heer sare ah loo isticmaalo oo dhan talaajad si aad u keydin karaa cunto iyo cunto diyaar u sii dheer tahay heerkulka daarmayaay'e. Maqaalkani waxa uu sheegi doonaa, Freon - waa in arrinta halkaas oo loo isticmaalo, waxa heerkulka waa.

History of daahfurka

ilo kala duwan magacaabo laba taariikhaha Freon ugu horeysay Avv - 1928 iyo 1931 sano. Sax in taariikhda dhalashada ee sanadka th ee refrigerant 1928. Waxaa markaas ahaa shirkadda u fiican farmashiyaha Frigidaire, taas oo hoosaad ka mid ah shirkadaha ugu General Motors, Thomas Midgley, keenay "walax mucjiso" iyo isaga siiyey magaca "Freon" ah. injineerada waaweyn ku hawlan soo saarka warshadaha gaaska this, ku soo galay Freon-12 naqshada sida «R» ah (in turjumaad «Refrigerant» waxay u taagan tahay refrigerant ama qabow). Taariikhda labaad ee dhalashada of Freon nepravlno xidho, maxaa yeelay, durba 1930 shirkadda ogeed Chemical Company, taas oo uu leeyahay in ay ka shaqeeyaan ayaa u abuuray in diiradda on saarka ee alaabta this.

Freon - waxa uu yahay waxan?

isku dar ah oo ethane iyo methane sida taagayo hooseeyo fluorinated miisaanka kelli hydrocarbon meesha atamka hydrogen waxaa lagu beddeli kara fluorine, chlorine, bromine. Si ballaaran loo isticmaalo qaboojiye units (qaboojiyaha, qaboojiyeyaal, hawo iyo N sidaas on.). yaab badan oo, Freon - waa gaas ama dareere ah? Jawaabta saxda ah waa: maalkii yeelan karaan gobolka jirka labadaba.

Noocyada ugu badan ee Freon

Science yaqaan in ka badan 40 nooc oo ah walaxda, kuwaas oo intooda badan waa la helay industrially. heerkulka Freon at kaas oo karaysa, noocyada kasta wuxu iska leeyahay:

• R11 - trichlorofluoromethane (t la karkaraya 23,8 ° C).
• R12 - difluorodichloromethane (la reflux t kulul -29,8 ° C).
• R13 - trifluorochloromethane (la reflux t kulul -81,5 ° C).
• R14 - tetrafluoromethane (la reflux t kulul -128 ° C).
• R134A - tetrafluoroethane (karkaraya kulul kula t -26,3 ° C).
• R22 - chlorodifluoromethane (la reflux t kulul -40,8 ° C).
• R600A - isobutane (la reflux t kulul -11,73 ° C).
• R410A - hloroftorokarbonat (la reflux t kulul -51,4 ° C).

Sida caadiga ah, qaboojiyeyaasha guriga shaqeeyaan on freon fasalka (Khladone) R-22, si loogu isticmaalo warshadaha iyo ganacsiga R-13 brand.

Freon - waa shay khatar ah aadanaha?

Ku dhowaad dhammaan noocyada kala duwan ee qalabka leeyihiin negative karaya, si kastaba ha ahaatee, iyo waxa loo isticmaalaa in xubno qaboojinta qalabka guriga, sida element maandooriyayaasha ee gulufyadii gaaska, fresheners hawada iyo aerosols kale ah. Sidaas daraaddeed markii xereen dhululubo laftiisa waa la qaboojiyey iyo Freon galo hawada. Haddii refrigerant aan la kululeeyo 250 digrii (heerkulka this, sii daayo walxaha sunta ah) waa dhib lahayn in ay aadanuhu, ma la odhan karaa in lakabka Allena ka. alaabta suuska The baabbi'iyo. Sababta ugu wayn ee godad Allena waa ka-soo-saarka iyo isticmaalka Freon la content sare ah udhigo chlorine iyo bromine. Baxsiga walxaha in qalabka guriga iyo urta aan la ogaan karaa aragga, qiyaaso yar qofkiiba leeyihiin saameyn ah kuma laha.

Waayo, soo kabashada ee lakabka Allena ka mid ah Dhulka iyo in la yareeyo wax soo saarka ee CFCs waxyeello wadamada Qaramada Midoobay ansixisay, saxiixdayna Protocol Montreal.

Waa maxay freon ee qaboojiyaha?

Modern qaboojiyeyaasha kombaresarada waxaa lagu soo bandhigay qaab kamaradaha kaalinta gudaha evaporator ah, oo ay ku jiraan refrigerant ah. Tani walax inta lagu guda jiro karkaraya iyo vaporization nuuga kulaylka ka qolkii iyo wareejinta nidaamka uumiga waxaa ku ah deegaanka. Sababtoo ah hawada tani waxaa la qaboojiyey si heer kulka la doonayo, iyo gaaska soo laabtay si hawadda iyo badala ay state of xulkii ee dareeraha ah a. Freon qaboojiyaha waa uun evaporator this. In si kale loo dhigo, waa qayb muhiim ah oo nidaamka, mahad oo qolladaha qaboojinta of unit qaboojiye ah.

Sidee ayaad ku ogaan saabsan dillaac ah ee Freon ka qaboojiyaha

Waxaa hubaal ah in walax this - mid ka mid ah qaybaha ugu muhiimsan ee shaqaynaya saxda ah ee qalabka. Natiijooyinka baxsiga Freon in waxyeelo ay ku qalab iyo awood si ay u isticmaalaan ujeedooyin kale. Sababta ugu badan ee dhibaatada this - dhaawac tube evaporator ama cilado soo saarta. Tan iyo markii ay tani tahay gaaska kacsan, ur ah, waa wax aan macquul aheyn in la ogaado ee receptors olfactory.

Si kastaba ha ahaatee, waxaa jira qaar ka mid ah calaamadaha in la aqoonsado dillaac ah. Freon qaboojiyaha waa cadaadis, iyo marka ay waxyeello evaporator tube, uu si tartiib tartiib ah uu bilaabo inuu dhici. Sidaas awgeed, in qaboojiye iyo qaboojinta heerkulka hawada qolkii soo baxdo, oo si deg deg ah nadiifiyey bilaabaan inay ka sii darto. Tanu waa calaamaddii ugu horeysay ee aad u baahan tahay si aad u hubiso daacadnimada nidaamka qaboojinta of qalab ah. Sida hore u soo sheegnay, Freon ma aha khatar nin heerkulka a ma ka badan 250 darajo, iyo waxa kululeeyo si heer kulka ah ee guriga suurtogal ma aha.

The meelaha ugu badan ee baxsiga refrigerant

First of dhan - goysyada biibiile this. In kabida, wax la abuuri karaa sida microcracks ah ay sabab u tahay hawlgal joogto ah qalabka iyo sababo la xiriira guurka warshada. Sidoo kale baxsiga Freon caadiga ah ee meelaha isku xira qaboojiye tuubooyinka evaporator iyo qaboojiyaha. Quwad lagu ogaan karaa by line soo laabtay, kaas oo isku xira qalbiga qaboojiyaha iyo evaporator ah.

Sida loo cusboonaysiiyo dillaac ah?

Buuxinta qaboojiyaha freon guriga suurto gal ahayn oo aan gargaar ka xirfadle. Tan iyo markii ay u baahan yihiin qalab gaar ah iyo qalabka (bamka vacuum, kabida gubi kala cayncayn ah qaybiyaha la cabirrada, Alxan bir ah, ka daadanayo gaar ah) shaqada. Waayo, ogaanshaha baxsiga ee tuubooyinka oo isticmaalaya qalab gaar ah oo u eg qalabka birta lagu ogaado. Ka dib markii sayidkii aqoonsado dhaawac iyo qaybtii shaabadeeyey, baabi'inta baxsiga, bamka vacuum la gareeyeen gaaska haray iyo mar kale oo la qalay. Buuxinta dhacdaa via xiriir buufin la gaaska in biiyaha ku yaal sanduuqa battariga ee kombaresarada qaboojiyaha, iyada oo la xidhiidha tube gaddoonka ah waxaa laga shaabadeeyey laba muhiimka ah.

Intaas ka dib, qaboojiyaha freon ah mar uu bilaabo inuu si fiican u wareejin iyo heerkulka qolalka lagu wadaa iyadoo la raacayo heerarka qalabka qaboojiyaha.
