<p>Dear David</p>

</p>
<p>Thank you very much for the useful links. Now I know how to control the temperature of a building. Is there any example of controlling the humidity also?</p>

<p>Ahmad,</p>
<p> I would recommend that you download the tutorial called "Temperature Level Control from Energy Rate Control " at:<br>
</p>
<p><br>
</p>
<p><a class="moz-txt-link-freetext" href="http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm">http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm</a></p>
<p><br>
</p>
<p>or if you are using v16</p>
<p><br>
</p>
<p><a class="moz-txt-link-freetext" href="http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex.htm">http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex.htm</a></p>
<p><br>
</p>
<p>It will explain some of the differences between calculating a building load and simulating the performance of HVAC systems. It will also lead you through an example of converting a load computation simulation into an HVAC system simulation.</p>
<p>kind regards,</p>

<p>Dear Jeff</p>
<p>Thank you for your guiding. I have simulated my HVAC system at nominal condition, alone not using the building model. Now I'm going to use this system connected to a building. Now my question is how should I match the HVAC cooling production to the building load
which is transient? should I control the temperature and humidity also or just the flow rate should be controlled to meet the load? </p>
<p>I couldn't find a similar example in TRNSYS examples. Could you send me an example in case of having some please?</p>
<p>Thank you</p>

<p>Ahmad,</p>
<p>There are literally hundreds of ways to control the temperature and humidity in a space. I would suggest you do some reading to figure out a common HVAC system given your climate and type of building - then you can begin to replicate that system in TRNSYS.

<p>Hello</p>
<p>I'm simulating a solar assisted coolig system for a building. The building cooling load is transient. so how the HVAC system should be controlled to cover the building load? I guess that the supply air temperature and humidity ratio should be constant (
a value in the comfort region ) and the air flow rate should be controlled using a variable speed fan to cover the cooling load. Is it right? any better idea?</p>
<p>Also I don't know how the control system should be? should I use a thermostat? </p>
<p>If any one can send me an example it will be very useful for me to learn</p>
<p>Thank you </p>
