You could use the Output Variables for the LoadProfile:Plant to output the heat transfer rate to the refrigeration load, use the Output Variables for the PlantLoop to output the total load on the plantloop, and calculate the percentage of the load that refrigeration load represents. Then, you could report the total chiller energy and multiply by the percentage to estimate the total chiller energy used to serve the refrigeration loads.

Then, you could report the total chiller energy and multiply by the percentage to estimate the total chiller energy used to serve the refrigeration loads.

Update:

To automate this, you could:

  1. Make an EMS Actuator for each output variable
  2. Make an EMS Program to do the math to calculate the result
  3. Make an EMS Output Variable to report out the resulting timeseries.
