I would like to evaluate the indoor comfort with OpenStudio. In particular I should evaluate the PMV index and the discomfort hrs (unmet load hours).

Is It possible with OpenStudio? Or do I have to use EnergyPlus? How should I do it?

In OpenStudio unmet load hours can be found in the EnergyPlus results at the end of the System Summary section (use Outdoor Air Summary hyperlink instead). There's also a nice measure to troubleshoot unmet load hours.

Results Summary tab > Reports > EnergyPlus Results

PMV can be added using the Predicted Mean Vote measure.

If your HVAC system is autosized then the unmet hours are commonly very low.

Or in your case it looks like you're using ideal air loads.
