Re: [TRNSYS-users] Likely bugs in Type655 and Type666

[knut.erik.enerstvedt@niva.no]

Hello,

You are absolutely right about this. There is a mismatch
between documentation and example datafile on one side and source code
on the other. The first column in the datafile should consist of COP ratios,
while the second column should consist of capacity ratios. There have been
some postings about this on the list in the past.

Best regards,
Knut Erik Enerstvedt
