What Factors Affect Refrigerant GWP Values?

Q:

What Factors Affect Refrigerant GWP Values?

A:

It’s not just refrigerants that receive GWP values. Really any gas can be placed on the GWP spectrum (R-22, for example, has a GWP 2,000x that of carbon dioxide).

Carbon dioxide is the gas that experts use as a benchmark for understanding how different gasses affect the environment. Factors that influence how a given gas scores include:

  • its absorption rate
  • how long it ‘lives’ in the atmosphere
  • at what wavelength the gas absorbs radiation
