[EnergyPlus_Support] Re: System for simultaneous heating and cooling

["FrancescoP" <fpasserini.tn@xxxxxxxxx>]

I think that there two problems:
1) modeling the fact that when some zones need cooling and some zones need heating the heat that is rejected by the chilled water loop is transferred to the hot water loop
2) modeling the fact that water can be taken from the acquifer and transferred to the water loops (the same quantity of water is discharged into the sewer system).

As regards the first point, is a post-processing in a spreadsheet necessary?
As regards the second point, probably I could simplify, e.g. I could model a closed loop (GroundHeatExchanger?).

Regards

In other words, it is a heat pump that works among the hot water loop, the cold water loop, and water coming from an aquifer. You can see pages 6 and 10 of this brochure:

The opposite during winter season. Probably there are some valves that are not represented in the picture.
