<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>
<p>Thank you </p>
