That would be greatly appreciated if anyone could help me with modeling Heat Recovery Chiller in EnergyPlus using HeatExcganger:FluidToFluid object. While there is an example file on modeling it using a WaterHeater:Mixed, I'm struggling with the HeatExchanger:FluidtoFluid modeling approach. There are few questions posted in this topic (including this link and this link. However, all is recommended was following the water heater approach.
In specific, I'm getting consisitently a severe error message that crashes my simulation run and says:"The "Loop Demand Side" connections are not on the Demand Side of a plant loop", while i just replaced the water heater by a heat xchanger and changed the branchs and loops accordingly.
Any help would be greatly appreciated.
