<br>Meanwhile, another weird phenomena appear: After running based on your solution in winter, indoor temperature becomes 35 °C also not 21 °C, although I set heating temperature as 21 °C; in summer, however, indoor temperature becomes 21 °C. Please see the Attached On-Line Plotter image.<br>

I think the point how to set that Cooling doesn't work in winter? The possible reason of that problem is that I also set a Mechanical Ventilation in winter (Tset=19 °C) and summer </font><font size="4">(Tset=17 °C). I guess Maybe </font><font size="4">the Mechanical Ventilation will influence on Cooling and heating?</font><br>

As far as I understand, the cooling set temperature you define
in your model is :<br>
</font></font>
<ul>
<li><font size="-1"><font face="Arial">24°C in summer, which seems
to be correct</font></font></li>
<li><font size="-1"><font face="Arial">and 0°C in winter... which
seems to be wrong, since you don't refresh your thermal zone
at 0°C in winter!<br>
</font></font></li>
</ul>
T<font size="-1"><font face="Arial">hat's why you obtain huge
cooling loads.<br>
BAL_ENERGY is not 0 because you heat and cool in the same time
in winter.<br>
</font></font>
<p>I think you'd better put for cooling temperatures <br>
</p>
<ul>
<li>35°C in winter (no cool) - heating temperature at 21°C<br>

<li>24°C in summer</li>

I make a simulation. The cooling set temperature is 24*Summer
schedule (2162 h to 6552 h), The heating set temperature is
21*Winter schedule (the rest hours). After running, however, it
appears WEIRD phenomenon. Please see the ATTACHED
Energy_zone.BAL file. During the winter period, there are Qcools
and Qcool is very large up to 47000 kJ. And then it results in
wrong BAL_ENERG, it is not 0.<br>
<br>
Please give me some advices and solutions to that!<br>

Many thanks in advance!<br>

Dear Trnsys users,
<div><br>
</div>
<div>In order to simulate a water-cooled chiller, first I need
to create the 2 external files for this component. </div>
<div>I'm trying to find some catalogues with information of a
40 to 45 kW water-cooled chiller but the web pages I run
into it, ask me to register, but I'm still waiting the
username and pasword. Does anyone has a catalgoue with this
type of info regarding this cooling capacity machine?</div>
<div><br>

Dear all,<br>
<br>
I cant make type673 heating mode to work. Cooling mode works
just fine but when I change the cooling control signal to 0
and heating control signal to 1 it doesnt work anymore. When
the heating mode is used nothing happens. Does anyone know
why?<br>
<br>
Best regards,<br>
