To determine which refrigerant has the highest Global Warming Potential (GWP), we need to look at the respective GWP values of each refrigerant. The GWP is a measure that compares the amount of heat trapped by a certain mass of the refrigerant in question to the amount of heat trapped by a similar mass of carbon dioxide, over a specific time period.
The GWP values for the three refrigerants in question are:
- OR-12: 10,900
- QR-134a: 1,430
- OR-1234yf: 4
By comparing these values, it is clear that OR-12 has the highest GWP among the three refrigerants, with a GWP of 10,900. Therefore, OR-12 (also known as R-12) is the refrigerant with the highest Global Warming Potential.
Select the correct answer: OR-12.
