Hello,
I am attempting to simulate a Water Side Economizer (WSE) in EnergyPlus 8.4. I am using a HeatExchanger:FluidToFluid
with the CoolingSetpointOnOffWithComponentOverride
option to override the chiller when possible. The simulation runs without any errors but the WSE never turns on.
I have looped at the FreeCoolingChiller.idf
file in the EnergyPlus example files but have not been able to distill any solutions to my current problem.
The branches, splitters, mixers, and branchlists appear to be working correctly. I believe it is a problem with using the control scheme/setpoints and the Loop option for the Component Override Cooling Control Temperature Mode
. I am using Loop because my condenser loop is actually connected to a river. I have allowed the condenser loop to go to 0.005 C and checked that the river temperature is below the 6.7 C set for the free cooling.
Is there a SetpointManager/Control Scheme I need to incorporate that I have missed? I was going to implement an EMS control scheme but figured I should get a simple configuration working first before dynamically adjusting the Condenser Loop.
Thank you,
Justin
