[bldg-sim] Modeling Packaged VAV system with PFP Boxes

Thank you for your response.

However, the PIU option is given only for cooling option set at chilled water coils.

As per ASHRAE I have to model this system with cooling option set at DX coils.

The powered induction unit (PIU) is essentially the same as the VAV system with the option of using terminal series or parallel fan units.

Subject: [bldg-sim] Modeling Packaged VAV system with PFP Boxes

I was comparing a proposed design system to a base-case system specified in ASHRAE 90.1 Appendix G using EQUEST. This base case system is a Packaged VAV system with Parallel Fan Powered Boxes. On examining the DX options given in the EQUEST system menu, the closest I could get is 'Packaged VAV with Reheat'. On switching to detailed mode the option for zone fans is deactivated.

Could anybody give any suggestions as to how I can model this Packaged VAV with PFP boxes?

Any help is greatly appreciated.

Thanks
