[Equest-users] WSHP(Heating HW loop has zero design flow) vs PVVT, PSZ, etc

[Nikola Kravik]

Brian, thank you for your valuable input.
The loop switch fixed the hhw loop error...

Best,
Nikola

Change your condenser loop type from condenser to water source heat pump.  That will allow you to put both your boilers and your cooling tower on the same loop.  Then delete the hot water loop as it is not used in the model.

Hi,

I'm trying to model WSHP's served by Closed circuit Fluid Cooler and Boiler.
I get the below error if I use WSHP; I

I read the users archive from Bill Bishop, Umesh and others  about WSHP approximations to PVVT or PSZ but when trying to run simulation it still kicks me out saying "zero design on the hhw loop" anything I'm missing?

Thanks,
Nikola
