[Bldg-sim] TRAINING: DesignBuilder EnergyPlus Simulation Training

Dear Forum,
The refrigerated warehouse we're modeling uses an "economizer" to help
unload the compressors in the winter. As I understand it, the system works
something like hot gas bypass for commercial air conditioners and routes
hot gas to the inlet of the compressor.
I don't see a direct method of modeling this, so I plan to create a
modified capacity curve for the compressors in order to represent the
impact of this "economizer".

   1. Do you have a better idea?
   2. Any cautions that apply to this approach from your experience?
