[EnergyPlus_Support] About the plant-condenser loops setup

["energypluser" <energypluser@xxxxxxxxxxxx>]

Dear All:

     I find that the maximum temperature setup in "the plant-
condenser loops" seems not be able to control the plant loop 
temperature at all.
     My plant loop constitution (supply side) is as follow:
     1. a electric chiller with the nominal volumetric flow rate 
equal to 0.007639 m^3/s, and i set the plant loop maximum volumetric 
flow rate equal to the nominal value.
     2. I set the maximum loop temperature equal to 15C for the 
purpose of controlling the return water of the chiller. But after 
simulation, the results show that the inlet water temperature of the 
chiller is higher than 15C for many times.
     I am sure that there is no node connection error. And the 
electric chiller is the only plant component in the loop.Mike tells 
me that it is impossible to controll the chiller flow rate except 
setting the chiller into a constant flow one. But I want to keep the 
flow rate variable and have some methods to controll the return 
water temperature.
     Could you please tell me the methods ?
 
     Thank you in advance!

                                                           charlie
