R134a (SUVA 134A), tshuaj lub npe: 1,1,2-- tetrafluoroethane, molecular muaj pes tsawg leeg: CH2FCF3, CAS Sau Npe: 811-97-2, molecular hnyav: 102.0, HFC refrigerant, ODP tus nqi yog xoom. Cov khoom siv thermal thiab lub cev ntawm R134a, nrog rau nws cov toxicity tsawg, ua rau nws muaj txiaj ntsig zoo thiab muaj kev nyab xeeb. Hfc-134a tuaj yeem siv tau rau ntau thaj chaw uas CFC-12 (dichlorodifluoromethane) tau siv tam sim no, suav nrog cov tshuab cua txias, cov khoom siv hauv tsev, cov tub yees me me, cov tub yees nruab nrab kub hauv cov khw muag khoom, kev lag luam thiab kev lag luam chillers , polymer foams, aerosol khoom, thiab magnesium alloy tiv thaiv gases.
R134a, raws li lub cim tshiab ntawm ib puag ncig cov tub yees, yog siv los hloov R12 (dichlorodifluoromethane), R22, feem ntau yog siv hauv tsheb cua txias, tub yees, freezers, dej dispensers, dehumidifiers, central cua txias (chiller) thiab lwm yam khoom siv cua txias thiab cua txias. .
Kev tiv thaiv roj: tiv thaiv roj siv hauv magnesium alloy ua.
Rau polymer foaming: Polymer foaming.
Rau aerosols: HFC-134A kuj tseem siv tau rau hauv aerosols nrog nruj toxicity thiab flammability yuav tsum tau; Hfc-134a tau tsim los ua tus neeg nqa khoom rau kev nqus pa (piv txwv li kev kho mob aerosols) vim tias nws tsis tshua muaj toxicity thiab inflammability.
Compressor manufacturers feem ntau pom zoo kom siv Polyol Ester POE (Polyol Ester) thiab Polyalkylene Glycol (Polyalkylene Glycol) (tsheb cua txias) refrigerant roj.
