Re: [TRNSYS-users] Problems with "Cooling" in TYPE 56
Dear Bernd,
Yor results are highly unusual, so it is difficult to give any help.
I wonder what the result would be if you switch the cooling to OFF?
Regards,
Arie

Thank you for the reply, perhaps I have not described the problem
exactly, so your answer does not match my problem. I try it again:
I have created a BUI-file without (!) a heating, only a cooling is
installed.
But in the results I have values also for heating (in QSENS and in
QHEAT), although there is no heating installed! Now I have tested
another model and I get the same surprise: Heating energy demand > 0
without any heating installed. The amount is lower than in the modell I
have tested a few days ago, but in my thinking it must be zero.
Thanks for any comments.
Regards,
Bernd.
