Hi all,

I have modeled an internal heat exchanger in Type534 in TRNSYS17 (the version without the plugin). It seems to be working great besides one issue. It seems the parameter “Coil Pitch” does not affect the outputs at all. I tried using various values from 0 inches to 10000 inches with no effect whatsoever on heat transfer through the HXs. All the integrated outputs are identical.

Has anyone else experienced this issue? If so, is the parameter not being used in the source code or am I missing something?

Thanks,

Nick LaHam
