In OpenStudio, the Glycol Conentration in the PlantLoop
object is wrapped by the glycolConcentration
parameter, which you can see from the SDK, is a int
value. I went into the source code on GitHub and found that the Forward translator multiplies this number to get is as a percentage. I wonder what was the decision behind this implementation.
Therefore, you have to input 50% glycol concentration as 50
. When the model get's translated, it will be multiplied 50*0.01
and be passed to the IDF as 0.5
.
