Re: [EnergyPlus_Support] Efficiency for AC equipment in EnergyPlus





William,
You are correct. Higher COP = lower operating cost and lower energy use.

Hi, Jim
Can I ask you one more question?
I know COP is used to measure efficiency for AC in EnergyPlus,
For my understanding, higher COP means low operating cost and higher efficiency. 
If I am wrong, please correct me!
Thanks a lot!

best,
William

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

Coffee conversation: Does â??freedomâ?? mean being uncommitted? If that's so, it means we have no wider vision than our own personal agenda and comfort. Only when we give up the freedom to do whatever we selfishly want all the time, do we discover a greater freedom: The freedom to love. Love can be considered a sort of â??slaveryâ??, a voluntary giving up of self for another, that makes the world better and stronger for this generation and the next.
