Could you provide more details about the problem?

I just checked with a simulation using the "RefBldgSmallOfficeNew2004_Chicago.idf" in the example files and "USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw" weather file that comes with the EnergyPlus v9.4 installation.

I think the EnergyPlus calculated value for PPD agrees with the Fanger equation (same equation in the EnergyPlus code here) with the maximum percentage error being 21%. For a PMV value of -0.30006, the PPD by EnergyPlus was 6.87, and the error in PPD calculation was 2.15E-06% which is very small.

Maybe we could help you if we got more details.
