Hfc R134A A / c tub yees
134a refrigerant yog ib qho kev tshawb fawb zoo kawg nkaus, suav nrog hydrofluorocarbon (HFC) compound ua los ntawm carbon, hydrogen, thiab fluorine atoms, nrog rau cov tshuaj formula CH2FCF3. Txawm hais tias nws muaj qhov muaj peev xwm ua rau lub ntiaj teb ua kom sov siab (GWP), nws raug cais raws li lub tsev cog khoom roj uas muaj kev cuam tshuam tsawg dua ntawm cov txheej txheem ozone piv rau chlorofluorocarbons (CFCs) thiab hydrochlorofluorocarbons (HCFCs).
Ib qho txiaj ntsig tseem ceeb ntawm 134a refrigerant yog nws kev sib raug zoo nrog cov tshuab cua txias uas twb muaj lawm. Nws tuaj yeem siv los ua kev hloov pauv rau cov tub yees qub xws li R12 (CFC) thiab R22 (HCFC), ua rau nws xaiv yooj yim rau kev rov kho cov cuab yeej uas twb muaj lawm yam tsis muaj kev hloov pauv loj.
