GWP Calculator
Calculate the environmental impact of refrigerant charges and leaks. Enter the refrigerant type and charge mass to see the CO₂ equivalent and understand the global warming impact.
Understanding GWP and Refrigerant Impact
Global Warming Potential (GWP) measures how much heat a refrigerant traps in the atmosphere compared to CO₂ over 100 years. R410A has a GWP of 2,088, meaning 1 kg of leaked R410A has the same warming effect as 2,088 kg of CO₂.
The HVAC industry is transitioning to lower-GWP refrigerants like R32 (GWP 675) and R290 (GWP 3) to reduce environmental impact and comply with F-Gas regulations.
Frequently Asked Questions
What is GWP?
Global Warming Potential (GWP) compares the warming effect of a greenhouse gas to CO₂ over 100 years. A GWP of 2,088 means 1 kg of the gas has the same warming impact as 2,088 kg of CO₂.
Which refrigerant has the lowest GWP?
Natural refrigerants like R290 (propane, GWP 3) and R744 (CO₂, GWP 1) have the lowest GWP. Among HFCs, R32 (GWP 675) is significantly lower than R410A (GWP 2,088).
Why is GWP important for HVAC?
F-Gas regulations phase down high-GWP refrigerants. Using low-GWP refrigerants reduces environmental impact, complies with regulations, and future-proofs installations against upcoming restrictions.
