Hi, I'm modeling a heat pump system that uses Well/Lake water. When I run the simulation I get the follwing error message:"Condenser Water loop heating equipment- has no attached primary".
The system consists mainly of a HP chiller with water cooled condenser and a Lake/Well loop type.

Bassam,

please attach your .pd2 & .inp so that we can view into your file and see
the issue better. The condenser loop for this system set up is your
geo-lake/well circulation loop-is this linked to your heat pumps? They
should be linked to 3 circulation loops.

Hi Pasha, here are the two preliminary files.
I appreciate your feedback.

Bassam,

your ciculation loop that you have labeld as "condenser water loop" is of
type lake/well---this type of loop needs to have a ground loop heat
exchanger attached to it for your heat rejection source...

I have added this component in your plant and your error now goes away. If
you don't know how to add a new piece of equipment, let me know and I'll
walk you through it.

See attached revised files attached.
