※ R-12 tub yees alias R12, Freon 12, F-12, CFC-12, fluorine ob chlorine methane, lub npe ntawm cov khoom muag muaj Freon 12, lub npe ntawm cov tshuaj fluorine suav 2 chlorine methane, lub npe lub npe Dichlorodifluoromethane, molecular type CCl2F2. Vim tias R-12 muaj cov khoom rau hauv CFC (thawj txwv ODS Class I Ozone-depleting Substances) -Tau rau tus txheej txheem ozone, thiab muaj kev txuag tsev cog khoom, yog li nyob rau hauv cov teb chaws tau tsim thiab qee lub teb chaws, tshiab cua txias, tub yees cov cuab yeej tau tso tseg ntxiv rau ntawm cov cuab yeej qub lossis qub qub; Tuam Tshoj tau txwv tsis pub tsim cov R12 refrigerants hauv xyoo 2007, thiab pib kho cov khoom siv yees tshiab thiab cov khoom cua txias.
R-12 Siv loj
Raws li cov khoom siv hauv nruab nrab thiab cov cua txias tsawg tshaj plaws, R-12 tsuas yog siv rau hauv cov tub yees, lub khov dej, qhov chaw txias, tsheb cua txias, kev lag luam huab cua txias, txias cia, kev lag luam tub yees, tub yees, xws li cov khoom siv yees siv. 2-Ob dichloromethane tuaj yeem siv tau rau hauv aerosol pob zeb, tus neeg saib xyuas lub cev, cov tshuaj tua kab mob, tshuaj tua kab, thiab lwm yam.
※ R-134a refrigerant alias R134a, HFC134a, HFC-134a, fluorine ethane, lub npe ntawm cov khoom muag muaj SUVA 134a, Genetron 134a, KLEA 134a, thiab lwm yam., Suav npe fluorine ethane, lus Askiv lub npe 1,1,1,2- tetrafluoroethane, tshuaj npe hu ua 1,1,1,2 - PTFE, molecular type CH2FCF3. Vim tias R-134a belongs rau HFC khoom (non-ODS Ozone-depleting Substance) - thiab yog li ntawd, tag tsis txov cov txheej txheem ozone, tam sim no lub ntiaj teb feem ntau pom zoo thiab pom zoo siv cov cua txias hauv cov cua txias, ntawm ib puag ncig tiv thaiv yees, dav siv nyob rau hauv cov khoom cua txias tshiab thiab kho txheej txheem ntawm qhov sib ntxiv ntawm kev pib thawj.
R-134a Main siv
R-134a raws li kev siv ntau tshaj nruab nrab thiab qis tshaj ib puag ncig tiv thaiv refrigerant, vim HFC-134a kev ua haujlwm zoo, ua kom nws ua tau zoo thiab muaj kev nyab xeeb CFC-12 hloov, feem ntau siv siv R-12 (R12, Freon 12, F-12, CFC-12, Freon 12, ob chlorofluorocarbons) tso rau hauv ntau qhov chaw, xws li: tub yees, lub chaw khib nyiab, dej dai luam yeeb, lub tshuab cua txias, lub tshuab cua txias, dehumidifier, txias cia, lag luam tub yees, dej khov tshuab, Mis nyuj khov tshuab, cav txias khov thiab lwm yam khoom siv tub yees, tab sis kuj siv tau rau hauv aerosol pob zeb, tshuaj aerosol, insecticide pob zeb, polymer (plastics) lub cev foaming agent, thiab magnesium alloy tiv thaiv gases.
Txawm hais tias lub R134a refrigerant yog Freon R12 feem ntau ntawm cov khoom siv yees tshiab, R134a thiab R12 physicochemical zog, theoretical cycling kev kawm thiab cov roj compressor tsis zoo li qub, yog li ntawd, rau thawj lub installation ntawm R12 refrigerant tub yees khoom tom qab muag kev saib xyuas, yog tias koj xav tau ntxiv los yog hloov cov tub yees, tseem tuaj yeem tsuas ntxiv R12, feem ntau tsis ncaj nraim rau R134a hloov R12 (uas yog, feem ntau tsis tso cai hloov pauv).
