[Equest-users] Loop to Loop Heat Pump Error

Pasha,
Like Nick, I had no problem getting the model to run using 3.65 build 7174 in DOE2.2 mode.
It also runs in 3.64 build 7130, once I remove the line “HVACDefaulted = 1” from the pd2 file.
A couple suggestions:

-        Go to the Miscellaneous tab of the chiller and Restore Default to the four Heat Exchanger inputs. The error message you sent makes me think these have non-default values.

-        Copy the .pd2 and .inp files you sent into a new folder and try opening it again.
Regards,
~Bill

Hopefully Nick’s software version control works. If not, maybe you can track down those keywords in the BDL(?) file – I forget – the file with the compiled syntax, where the INP doesn’t echo back fields with default values?

Thanks David,  at this point I just don’t know.  I looked through the .inp file too and couldn’t find those keywords either.  That is when I turned to the group for more help.
I’m completely stumped on this one...

Would it bug you to learn this loads and simulates without error on my end?

Gut check:  are you being deliberate to open and simulate with the “release testing” build 7174?

Hi All,

does anyone have any experience with modeling the Loop to Loop Heat Pump chiller?  I'm getting the following error in my file, and right now I am auto-sizing everything just to test it to get the file to run.  I cannot locate/find where the Qhx Design, SupFlow, SupTi, SupTo key words are linked too.  The heat-Exchanger: HRC-T1 is the name of my LtLHP Chiller that I input on the loops.

I've looked through the DOE-2 documents for LtLHP chiller and I can't find where this error is occurring so that I can fix it.  Any insight you can offer will be appreciated.

I've also attached my .pd2 & .inp files if anyone is inclined to look at them.  Thanks in advance for sharing your thoughts and your brains with me!
