[Equest-users] PERFORM-DATA-AC Error

[A Ramirez Zarzosa]

Thank you Christopher,

 

The FOCS WATER 7240 Capacity is 1906 Kw, which is 6,5 MBtu/h, yes it was a units coma error converting units. Cleaning all of them the problem persists.

 

Best Regards,

You will also find that the capacities for the chillers and boilers are too high.  For example, Chiller 2A FOCS WATER 7240, capacity = 6503.5.  BDL reports CAUTION, Value greater than the maximum of 100.  Note, 6503.5 means 6503.5 million BTU/hr, 541,960 tons!

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.
