Report Units:Pressure:in.wg,Duct lengths:feet,Duct sizes:inch,Airflow:CFM,Velocity:ft.lmin,Temperature:F Notes: Static pressure available values for return ducts are at the entrance of the duct For supply,they are at the exit The cumulative static pressure loss value for a return trunk is with respect to the entry point of the return runout upstream with the highest static pressure available. Total and cumulative static pressure loss values for the supply main trunk include any device pressure losses entered,and the cumulative may also include the total static pressure loss of the return side.

Calculations are performed per ACCA Manual J 8th Edition,Version 2,and ACCA Manual D. All omputed results are estimates as building use and weather may vary. Be sure to select a unit that meets both sensible and latent loads according to the manufacturer's performance data at your design conditions. Monday,November 04,2013,12:09 PM
