Re: [TRNSYS-users] Problems with "Cooling" in TYPE 56

[bdo@stb.rwth-aachen.de]

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.
