Hello,<div><br></div><div>I'm using eQuest to look at differences in performance between airfoil and forward curved supply fans. I'm using a 63% total efficiency for the forward curved fans, and a 75% total efficiency for the airfoil fans, but am still getting greater energy consumption in the case with airfoil fans than for the case wit forward curved fans. I had thought that airfoil fans were supposed to be more efficient at part load and full load than forward curved fans. Is this not the case? What's the reason for this discrepancy?</div>
