<DIV><FONT face=Tahoma size=2>Dear Trnsys-users,</FONT></DIV>
<DIV><FONT face=Tahoma size=2></FONT> </DIV>
<DIV><FONT face=Tahoma size=2>I am trying to model a multizone building
with a humidification and dehumidification </FONT><FONT face=Tahoma
size=2>system which </FONT></DIV>
<DIV><FONT face=Tahoma size=2>has setpoints respectively at 40% and 60% relative
humidity. </FONT></DIV>
<DIV><FONT face=Tahoma size=2>This is done </FONT><FONT face=Tahoma size=2>by
adding humidification and dehumidification to the heating and cooling type
respectively</FONT></DIV>
<DIV><FONT face=Tahoma size=2>in the building model. However, I have the problem
that e.g. if the cooling is off, the dehumidification</FONT></DIV>
<DIV><FONT face=Tahoma size=2>is also not working, and thus the relative
humidity exceeds 60%.</FONT></DIV>
<DIV><FONT face=Tahoma size=2></FONT> </DIV>
<DIV><FONT face=Tahoma size=2>My question is thus, Is it possible to add
dehumidification without cooling or humidification without </FONT></DIV>
<DIV><FONT face=Tahoma size=2>heating in the building model, or are both always
coupled? Is there any way to solve this problem?</FONT></DIV>
<DIV><FONT face=Tahoma size=2></FONT> </DIV>
<DIV><FONT face=Tahoma size=2>Thanks a lot for your help.</FONT></DIV>
<DIV><FONT face=Tahoma size=2>Best regards,</FONT></DIV>
