Hi! I'm using OpenStudio to model a supermarket. As I'm trying to study the HVAC consumptions the several freezers(and also other electric equipment) that the supermarket has will influence the HVAC consumptions. In my model "Loads" tab I have 3 fields to fill: Fraction Latent, Fraction Radiant and Fraction Lost. I don't know, for each equipment that a supermarket has, what values should I introduce in this fields. Is there any informations/tables where we can obtain this values for each different equipment? Can I define the freezers influence on interior temperature from other way instead of using these electric equipment parameters? Thank you

The COMNET energy modeling guidelines provide information on the modeling of commercial refrigeration power use but it doesn't include a discussion on the assumptions for fraction latent, etc.
