What Is Refrigerant R143a?

Refrigerant R143a, also known as 1,1,1-Trifluoroethane, is a hydrofluorocarbon (HFC) used primarily in refrigerant blends for cooling applications. It has the chemical formula C₂H₃F₃ and is part of the HFC family, which was developed to replace older chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) due to their ozone-depleting potential.

Key Characteristics
Chemical Structure: C₂H₃F₃ (1,1,1-Trifluoroethane).
Molecular Weight: 84.04 g/mol.
Boiling Point: Approximately -47.24°C (-53.03°F) at atmospheric pressure.
Global Warming Potential (GWP): R143a has a relatively high GWP compared to natural refrigerants, with a GWP of around 4470 over a 100-year period.
Ozone Depletion Potential (ODP): 0, indicating it does not deplete the ozone layer.
Flammability: R143a is classified as non-flammable under standard conditions.

Applications
1. Refrigerant Blends: R143a is often used as a component in refrigerant blends such as R404A and R507, which are common in commercial refrigeration, including supermarket freezers and refrigerated transport.
2. R143a is an important component in the replacement of R502.
