[EnergyPlus_Support] Question about computation of convective internal loads.





Hi everyone!

I have a question about how the convective internal loads are computed.

This is one of the components for calculating the total heat load contributions in the zone system temperature computation. From what I understand from reading the Engineering reference manual and Input-Output reference manual, this is computed from the lights, people and electric loads in the building. 

I am trying to model a supermarket building, which has refrigeration racks and cases.

The convective internal loads values that I get as output is way higher than the convective loads by the people,lights, and electric loads in the building.  And they dont seem to tally! 

Any reason as to why this might be happening? Will any other factor contribute to this component .. like the refrigeration cases, compressors, etc.? 

Any pointers or help in this regard will be greatly appreciated!

Thanks!
