<br>
I forgott to say that the supply air temperatures from the AHU are 20°C for
winter and 18°C for summer. i could understand that there is no change in
winter as my set point is 20°, but in summer with a set point temperature
between 24-28°C there should be a difference on the cooling load when sending
more or less air<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

<br>
I am simulaitng an AHU coupled with a secondary system for heating and cooling.
For the secondary system I am using the heating and cooling type manager from
Type 56. What I obtain is independtly from the air change rate imposed by the
mechanical ventilation, the cooling and heating loads of the type manager
remain the same. Are the heating and cooling type managers not adequate to
simulate this or I am doing something wrong?<br>
<br>
Thanks in advance!<br>
