      "Temperature Level Control from Energy Rate Control " at:<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>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
