equest refrigerant error

Hi,

Anyone know what might cause this?

***ERROR********************************************************************
***

Table: R-404A has a row that is not

well behaved and cannot be used to lookup other values

(not continuously ascending or descending). Row: 1

The only reference in my INP file is:

"Cooler Multiplex" = REFG-SYSTEM

REFRIGERANT = "R-404A"

Which pulls the library entry (that I have not touched):

$LIBRARY-ENTRY R-404A REFRIGERANT Refrigerants

.

SATURATED-T

(-60.000,-54.359,-48.718,-43.077,-37.436,

-31.795,-26.154,-20.513,-14.872,-9.231,

-3.590, 2.051, 7.692, 13.333, 18.974,

and on and on

Thanks,

Shaun

Hi Phil,

Thank you for taking a look at this. It took me a some hours of fiddling
around but I did manage to get it to run. I'm not completely sure it had
anything to do with the Refrigerant. It has again stopped running as I
continue to edit and the message I get now is "12 Bad Building Components"
which is an absolute show-stopper -- eQuest provides no explanation. When I
did get the model to run, I would get a boatload of "MechEquip_Sim
convergence failure" cautions, again unexplained. Needless to say, the
refrigeration version of eQuest is challenging.

I started out building off the Grocery model, simplified the refrigeration
entries, and found I had to edit the INP file in a text editor -- the
interface seems to cause lots of problems. I have to say, though, it's a
shame these refrigeration routines are not built into the core Equest
product. Very useful.

I'm continuing to work on it. Hopefully I can get it running again. If I
do, and it's stable, I'll share the file.
