ACH in hospital operating room
ACH in hospital operating room
(OP)
Greetings everyone,
I know that ASHRAE Standard 170 dictates the ventilation and combination ACH for different type of rooms in healthcare facilities. I was wondering is there a way to reduce the combination ACH if the ventilation ACH are increased? I mean, if the room requires 20 combination ACH with 4 ventilation ACH, can the ACH be reduced to say 15 if they are 100% OA?
Thanks for your time, any help will be greatly appreciated.

Some hospitals have their own requirements. Check with your architect medical planner, some doctors require a minimum of 65F in the room, meaning you need even higher ACH.

The VA allows for decreased ACH during unoccupied periods, but maintaining the relative dP and being able to go to full operation for emergency service make it a challenge. Our ORN's are not fond of the idea, and I don't care to argue with an ORN about her own room. Even if it is allowable, are you sure you want to do it?
