Re: [EnergyPlus_Support] Efficiency for AC equipment in EnergyPlus

["william Lee liwenliang1984@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

I got the reference model (large hotel) from DOE website, they do have COP there, but no value, it looks like this building is using other HVAC system instead of DX Coil or Chiller you mentioned.

best,

What files do not show a COP? (since both of the screen captures you included have COP)

Hi, James,

For some buildings, I didn't find either Coil or Chiller for efficiency, is there some thing wrong here, I used the reference model from DOE.

William,

For a DX coil, have you seen this? (COP is a measure of efficiency)

For a Chiller, it's in the Chiller object

Hi all,

       I am just wondering how can I set up efficiency for AC equipment in EnergyPlus, I looked around almost all the parameters in EnergyPlus, I didn't find the parameter for AC efficiency.

Thanks!

William
