[Equest-users] PERFORM-DATA-AC Error

[Nicholas Caton]

Do you have an .inp of a recent, stable (at least completing simulation
attempts) iteration for the same project prior to exhibiting these errors?
It may prove fruitful to compare against the most recent version.



The text & position of the referenced chiller BDL errors specifically
suggest something awry with the retrieval of the library screwH20 curves…
However perhaps more importantly I observe the eQuest interface is not
behaving normally (for example, neither chiller accepts a CW loop
assignment), and even when the offending chillers are removed, a large
number (100’s) of new bdl errors occur concerning missing system inputs
(which exist), building shades, and zone HVAC inputs appear…



My gut tells me the sheer size of this model is a primary factor – appears
to be a full campus of buildings.  The chillers and associated inputs may
not be the true source of this instability.  It might prove fruitful to
break the model up into smaller portions.

*Hi Guys,*

I have two screw chillers, with water cooled condensers. In the Chiller
properties, in both of them in the “Condenser type” box: is written “water
cooled”. When I try to run the simulation. Two errors arise that does not
allow me to perform the simulation.



2 error(s) found in project’s BDL input file.
------------------------------

*BDL. Input/Underline:*



0.00975338, -0.00005891, -0.00458177)  --



*BDL Error:*



PERFORM-DATA-AC in Chiller 2A FOCS WATER 7240 has Expression Evaluation
Error: BDL Symbol ‘AIR COOLED” not found.

*BDL. Input/Underline:*

*BDL Error:*



PERFORM-DATA-AC in Chiller 3A FOCS WATER 7240 has Expression Evaluation
Error: BDL Symbol ‘AIR COOLED” not found.

I would be glad if you advice me on how to solve this problem.



Many Thanks in advance.
