Re: [EnergyPlus_Support] Question about the initial load when turn on the chiller



For the first hour of operation:

1) does the chiller part-load ratio match for the real vs tested data?
2) does the return water temperature match for the real vs tested data?
3) does the outdoor temperature match for the real vs tested data?
4) does changing the loop volume change these results?
