[EnergyPlus_Support] variable speed pump

[Helen Xing <hxing@xxxxxxx>]

Hello, there,

I am simulating a commercial building with variable speed pumps and 
fans.  Found that quite a few days in summer, LA, the chilled water flow 
rate drops suddenly at some point during the day while returning water 
temperatures up quite a bit and overall loads not changing much.  There 
seems no obvious reason for the chilled water flow rate to change.  This 
strange pump behavior distorts the total load profile.  I was wondering if 
you could possibly take a look at the original input file which is uploaded 
to Files\Problem_Submittals\ hxing \hxingmodel.idf and offer some help.

I appreciate your time.
Helen Xing
