Ahmad,
I would recommend that you download the tutorial called
"Temperature Level Control from Energy Rate Control " at:
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex17.htm
or if you are using v16
http://sel.me.wisc.edu/trnsys/downloads/tutorials_and_examples/tutex.htm
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.
kind regards,
David

Dear Jeff
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?
I couldn't find a similar example in TRNSYS examples.
Could you send me an example in case of having some
please?
Thank you

Ahmad,
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.

Hello
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?
Also I don't know how the control system should be?
should I use a thermostat?
If any one can send me an example it will be very
useful for me to learn
Thank you
