Dear All<br><br>I am doing an experiment to see the effect of supply CFM on energy consumption of building.<br>I set AHU with VAV and area of model is 25000Sqft.<br><br>I am getting following results<br><br>

<br clear="all">I want to know that with increase of supply CFM , TR is increases even having VAV system.<br>Is over sizing of AHU fan with VAV have harmful effect on energy consumption and why TR is changes.<br>-- <br>With Thanks and Regards,<br>
