I have set the airflow for the unit at 7,500 cfm. When I look at the SV-A report, the airflow is showing at 9,090 cfm. I then tried going into each individual sub-zone and setting the airflows. The sub-zones airflows in the SV-A report are higher than what I have entered, and the total airflow still remains at 9,090. I am thinking perhaps I have picked the wrong system. I assumed I could use a packaged single zone for this case. Perhaps I should be using a different system type? </div><div><br></div><div>The other part of the
question is how do I model the fact that is 100% OA? Th only reasonable solution I have found is to have the exhaust air in each zone track the supply flow. It is also asking for either static pressure and efficiency, or kw/cfm. As the exhaust is at the unit itself via heat recovery using a heat pipe, I am not sure what I should be entering here, as the fan details would be entered at the unit itself. Thanks in advance for any help. <br></div><div><br></div><div>Brad Robinson<br></div></div></body></html>
