[EnergyPlus_Support] Ice storage system in EnergyPlus

["mingming_zuo" <mingming_zuo@xxxxxxxxx>]

Hi all, I tried to model ice storage system with different kinds of 
operation strategy in energyplus such as ice tank priority,chiller 
priority.By doing these work, i come to a question:what control 
strategy of plants in a loop can energyplus achieve? Can it just act as 
it is said in the input&output reference? I think it may not be the 
fact. I would like to share some of my failure with you, which may help 
us have a good understanding of energyplus and make better use of it.In 
one of my several models, the chiller and ice tank is configured in 
series with the chiller upstream.Two operation schemes,one is Cooling 
Load Range Based Operation and the other is Component Setpoint Based 
Operation, are also defined in the Plant-condenser control.Cooling Load 
Range Based Operation is set to run during peak hours while Component 
Setpoint Based Operation runs during the night time. Moreover, we 
define ,in plant equipment list,the ice tank first and then the main 
chiller, hoping the ice tank will satisfy the cooling load 
first.However the results of this model is really disapointed and the 
chiller still has its priority in satisfying the cooling load. I also 
upload an idf file named IceStorage-Series-ChillerUpstream.idf which is 
an example file with some related parts redefined.I hope it can help us 
to learn more.
