EPA 608 Core · Ozone Depletion · Medium
R-410A has a GWP of about 2,088. What does that mean?
Answer: B. A pound of it warms the climate like 2,088 lbs of CO2.
- AIt holds about 2,088 lbs of refrigerant per ton.
- BA pound of it warms the climate like 2,088 lbs of CO2.✓ Correct
- CIt depletes ozone 2,088 times faster than R-11.
- DIt boils at 2,088 times atmospheric pressure.
Why B is right
Global Warming Potential compares a gas with carbon dioxide over 100 years: releasing 1 lb of R-410A has about the same warming effect as 2,088 lbs of CO2. GWP says nothing about ozone depletion; R-410A's ODP is zero.
