[EnergyPlus_Support] isolation valve at the water-to-air heat pump

[Ery Djunaedy <ery.mailinglist@xxxxxxxxx>]

All,

I am trying to develop an energy efficiency measure for water source 
heat pump system. This one involves the installation of VFD on the main 
circulation pump which will reduce the flow rate of the water when there 
is no call for cooling or heating from the heat pumps.

The only problem is that the model for this system in EnergyPlus does 
not include an isolation valve, i.e. even if there is no call for 
cooling or heating, the water still flows through the heatpump (through 
the bypass). That means the water in the main water loop will always 
flow at the design flow rate, which means the VFD in the main pump will 
be useless.

Any thoughts on how I can "install" the isolation valve in EnergyPlus?

Thanks,

Ery
