Hospital Operating Room 1

[fayazdin1]

Dear friends,

I am working on a surgical suite, where there are two operating room 30 sq. m each and a corridor with small sterile storage room.

AIA & ASHRAE call for min 15 air changes per hour (minimum).
I know VFD and VAV boxes are specified to turn-down supply air in unoccupied mode, but what if energy is very cheap?
Is there any other reason to have VFD & VAV boxes in hospital operating room?
The project is in Africa.

Sincerely,
Fayaz

Other reasons than energy costs? Here is one thing I can think of. If the room(s) is(are) unoccupied would you still have enough cooling load to provide decent return temperatures to your chillers to avoid frequent cycling?

Loading of the HEPA would be another reason. Otherwise, you would need to start by oversizing flow.

There is no such thing as cheap energy. Wasting energy is a crime against nature, no matter how much energy is available. I would think by now the whole world would be "green". Use the VFD and VAV boxes.
