[EnergyPlus_Support] Questions about the Coil Model

["deserteagle_zhou" <yp5166@xxxxxxx>]

Hi,all,
I have two questions about the  DX Coil Model .
1.For the DX Coil Model -- DX Cooling Coil Model, there is a 
sentence in the EngineeringDoc.Doc ,¡°The total cooling capacity 
modifier curve (function of flow fraction) is a quadratic curve with 
the independent variable being the ratio of the actual air flow rate 
across the cooling coil to the rated air flow rate (i.e., fraction 
of full load flow).¡±  The ¡° the actual air flow rate across the 
cooling coil¡± seems to be a mean value in a timestep.What does that 
mean exactly? How can I define the "the actual air flow rate
"  from the manufacture's catalogue data in order to get the 
modifier coeficient?
2. From the formula of PLR, what do "sensible cooling load and 
steady state sensible cooling capacity" mean respectively? How does 
the program calculate them(Is latent cooling load neglected)?
Any suggestion and guide will be appreciated.Thank you in advance.

Eric
