  • Duct layout design:

    Method of duct design: Equal friction method.

    Software used : Mc Quay Duct Sizer.

    Duct system : VAV single duct system.

    Parameters considered for sizing:

    Volume flow rate of air.

    Velocity of air.

    Pressure drop.

  • System inspector & PD report:

    Finding critical path.

    Finding total pressure drop of system by revit PD report.

  • Clash detecting

    & Resolving:

  • Equipment selection:

    Selection of Supply and Exhaust FAN

    Selected fans:

    1. Floor wise toilet exhaust fan : Centrifugal- inline direct-

    driven.

    2. Terrace exhaust fan : single inlet single width (SISW) fan.

    3. Supply air fan : backward curved centrifugal fan.
