A: CO2
B: CFC-11
C: HFC-23
D: HCFC-22

参考答案: B

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

CO2 is a natural refrigerant and has an ODP of zero.

CFC-11 and CFC-12 set the bar for ozone depletion potential against what all other refrigerants are measured.

HFCs have a negligible ODP but a higher global warming potential (GWP).

HCFC-22 has a low ODP, but HCFCs were still banned under the Montreal Protocol.
