What does ODP stand for when comparing refrigerants?
a.Oil Displacement Percentage
b.Ozone Depletion Potential
c.Overall Design Performance
d.Operating Discharge Pressure
解析
ODP means Ozone Depletion Potential, a value that compares a substance's ability to destroy stratospheric ozone relative to CFC-11, which is assigned an ODP of 1.0. It has nothing to do with discharge pressure, design performance, or oil displacement. HFCs have an ODP of zero because they contain no chlorine.
