One approach that comes to mind is to use SetpointManager:FollowSystemNodeTemperature, so that the outlet setpoints can be made to track the other side’s inlet temperatures. And then use a modulated setpoint control type on the HX.

Subject: [EnergyPlus_Support] HeatExchanger:FluidToFluid as "fluid exchanger"
Dear all,
In order to couple two plant loops, I need to use a HeatExchanger:FluidToFluid component.
But in the situation I want to model, the fluid itself (hot water for space heating) is exchanged:
This means I have an "Ideal" heat exchange, and I would like:
- the flow rates on supply and demand side to be equal
- the supply inlet temperature and demand outlet temperature to be equal
- the demand inlet temperature and supply outlet temperature to be equal
Actually, when I use HeatExchanger:FluidToFluid with control type "OperationSchemeModulated", this is not far from being the case.
But is there a way I can ensure that this is really the case ?
Thanks!
Robert
