Please refer to the attachment. We are seeking advice on the best way to calculate the airflow in a space where there are transfer grilles. Currently our Transfer grilles are classified as “exhaust air” with the connector set as a “fitting”.
Because there is no transfer air option (and the transfer could essentially go either way) we have selected exhaust as the classification. Because of this, the room we have showed has 120l/s of actual exaust and 120l/s of Transfer. The space is showing 240. Is there any way to negate the transfer in this calculation?
