What is the GWP of R-134a refrigerant?
The baseline measurement of GWP is Carbon Dioxide which is set at a GWP of 1. R-134a has a GWP of 1,430. Think about that for a moment folks. That’s over fourteen-hundred times that of Carbon Dioxide. These high GWP refrigerants are known as ‘Super Gases,’ due to the effect that they have on the environment.
What kind of refrigerant was used before 1995?
