is water loop inter-acting with air loop?
Posted: Fri Sep 02, 2011 2:16 am
In IES ApachHVAC, the water loop is defined with "chilled water loop"
The air loop is building by draging, droping and definding the loop.
A very interesting thing is whether the water loop is interacting with air loop? say, when we define a small chiller, and a proper air side (FCU or AHU), what will happen?
I tried for a small room. The result is not so encouraging. When the cooling coil size is correct, no matter what the chiller size is, the internal temperature will be held around design temperature.
When the air side is under sized, the temperature can not be held.
Does this mean the chilled water loop is just used to calculate the pump energy and chiller energy? and they do not interact with actual building load and air side.
Hope I am wrong and looking forward to get reply regarding this.
