I am looking at a simple VAV system and using Ventilation Rate Procedure on it. Below is a snippet from the EnergyPlus output.
The parameter Xs is very clearly defined as Xs = Vou/Vps. In the table below, I would therefore expect the following:
AHU-1 0.187 AHU-2 0.164 AHU-3 0.166 AHU-4 0.183 AHU-5 0.183
Yet, the table shows:
AHU-1 0.181 AHU-2 0.146 AHU-3 0.154 AHU-4 0.183 AHU-5 0.183
Any idea why that is so?
