Fan Coil with economizer mode 1

[austinpro]

Please let me know if you know any fan coil manufacturer that provide option to run them in air side economizer mode.

I've never designed fan coils with economizer, but you could talk to your local trane rep, I think that would be a good start. What tonnage are we talkin here?

 

[ChrisConley]

The 'Destiny' series of fan coils from McQuay has this option I believe. It is a semi-custom line, and not the cheapest option likely.

The capacities are not very big. Somewhere ranging from 3-10 Tons.

I will check Trane and McQuay. Thank you for your opinion.

Airside Economiser? That would require full volume OA ducting to the fan coils. You may as well put in a central AHU at that point.

 

[MechEngNCPE]

I agree, just go with an rtu or ahu w/ full economizer, your ducting anyway.

Make your own economizer - two motorized dampers and an exhaust fan. Outside air damper opens full, return air damper closes and fan energizes when outside air conditions are satisfactory.

Most mfg. offer a filter mix box option that will work the “air tunnel” on the fan coils.

The unit ventilators offer an econ section too.

If you have numerous units and the fan coil mfg does not offer a mixing box use you use
