James and fellow eQUEST users, have you found an answer or suggestions
about how to model this situation?
 
Thanks,
 
Otto
 
 
I am using eQuest v6.2 and receive a zero design condenser water pump
flow error on my model of a hybrid closed loop ground coupled vertical
bore system with integral closed cell cooling tower attached to a water
to water heat pump serving four pipe fan coil units.  I have been able
to set up the same using a surface water with cooling tower but receive
errors in zero design flow in my condenser water pumps.  I am using the
detailed editor and have confirmed that design flow is specified in each
of the pumps attached both on the load and source side of the water to
water heat pumps.
Has anyone been able to successfully run water to water heat pumps with
closed loop bores?  If so, have you been able to attached a closed cell
cooling tower to it?  I appreciate any and all guidance and thank you in
advance.
