Nevertheless, these terminals maintain the VAV energy savings at the central fan.
I feel like the fan powered (plenum reheat) is less of a thing today honestly. With all LED lighting, there isn't as much heat in the plenum to grab anymore. Honestly, if you can get by with 15% OA on the RTUs, then you don't have high people density, or you aren't doing ventilation calcs correctly. . First cost of electric reheat on boxes is .Reheat Type: Fan Powered; Fan Control: Series (technical support configuration) The thermostat controls the zone damper, local reheat, and series fan with the following outputs: (Y): 24VAC Output – Damper Open (Y2): 24VAC Output – Damper Close (if an open/closed or floating damper actuator is installed) (W): 24 VAC Output – Reheat Enable
Since the primary air is VAV, there is significant fan work savings. Using plenum air for reheat offers additional efficiency. Parallel fan-powered VAV systems are more efficient than series fan-powered VAV because the box fans are used only when required. The following are some considerations outlined in ASHRAE Std. 90.1-2016.To add - you’d use them in perimeter zones if you have electric reheat at the boxes. Since you need a minimum of 70-75 CFM/kW to keep the electric strip heater from tripping, it’s a good application for parallel fan powered boxes. When you need heat, the fan comes on. When you don’t, the box can go down to the minimum driven by . I udnerstand if there is electric reheat you want to keep air moving across it, but if the boxes are served by a complete conditioning system, what advantage are fan powered boxes? Reply 10-19-2004, 10:27 PM #2Overview. The Price FDC, series flow, fan powered terminal unit, is designed to supply air volume to the occupied zone in response to a control signal..

Series Fan units offer substantial operating savings which can be realized through the recovery of waste heat, and night setback operation. The Variable Air Volume terminal recovers heat from lights and core areas to offset heating loads in perimeter zones. Additional heat is available at the terminal unit using electric or hot water heating coils. The box will have heat capabilities if it is a perimeter box. It could be done with electric heat or hot water (coil). If a call for heat comes from the zone, the box will throttle the damper back and use Plenum air with the fan inside the box engaging. . On a series fan powered box, the fan runs continuous and the air valve modulates between . I'm working on redesigning a tenant space that has existing parallel fan-powered boxes with electric strip reheat. I need to pick out some new boxes.
