The difference between r134a and hfc-134a
Molecular formula: CHF2CHF2, molecular weight: 102.03 boiling point: 26.26 ℃, the critical temperature: 101.1 ℃, the critical pressure: 4067 kpa.
Molecular formula: CH2FCF3, molecular weight: 102.03, boiling point, critical temperature 26.1 ℃, 101.1 ℃ critical pressure, 4010 kpa
It can be seen from the above that R134a and HFC134a are two different substances, but their physical properties are basically the same, and they can be substituted by each other. Both R134a and HFC134a are ODP values of zero. Its low toxicity makes it a very effective and safe alternative to the cfc-12 used in the refrigeration industry. R134a and HFC134a are mainly used in automobile air-conditioning, household appliances, small fixed refrigeration equipment, medium-temperature refrigeration in supermarkets, industrial and commercial refrigerator.
