<p> I am not aware of such an example or tutorial. However, the
principal is the same as for controlling temperature. Define a
humidistat that watches the zone RH or humidity ratio then pass
the humidistat's outputs to appropriate
humidification/<wbr>dehumidification equipment that acts on the air
stream that is introduced into the zone.</p>

<p> I would recommend that you download the tutorial called
"Temperature Level Control from Energy Rate Control " at:<br>

<p><br>

<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>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>
