What statement is true regarding Hydrofluorocarbons (HFCs)?
A: HFCs have high ozone depletion potential
B: Many HFCs have a significant global warming potential
C: HFCs are scheduled to be banned under the Montreal Protocol

参考答案: B

本题解释:
Notes:

Reference: The Treatment by LEED of the Environmental Impact of HVAC Refrigerants

HFCs have a low ozone depletion potential, not a high ozone depletion potential.

HFCs typically have a low ozone depletion potential but a high global warming potential.

HCFCs, not HFCs are scheduled to be banned under the Montreal Protocol

NH3, CO2, and propane are types of natural refrigerants and are not part of the hydrofluorocarbons (HFC) refrigerant group.
