[EnergyPlus_Support] Refrigeration "economizer"

["Jim Dirkes jim@xxxxxxxxxxxxxxxxxxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

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 within the refrigeration objects, 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?
