What is the Ozone Depletion Potential of HFC-134a refrigerant?

HFC-134a, also known as 1,1,1,2-tetrafluoroethane, has an Ozone Depletion Potential (ODP) of 0. This means that HFC-134a does not contribute to the depletion of the ozone layer. The ODP is a measure of a substance's ability to damage the ozone layer compared to chlorofluorocarbons (CFCs), which typically have higher ODP values because they release chlorine atoms that actively destroy ozone molecules.

The designation of a refrigerant as having an ODP of 0 indicates that its use is considered environmentally friendly concerning ozone layer protection. This characteristic is particularly important as regulations aim to phase out substances that harm the ozone layer, such as CFCs and HCFCs, while promoting alternatives like HFCs that are less harmful.

In contrast, options that suggest an ODP greater than 0 indicate some potential for ozone depletion, which HFC-134a does not possess. Thus, the information about HFC-134a clearly identifies it as a suitable refrigerant in applications where minimizing environmental impact is a priority.
