Hi All,
I'm involve in a Hospital design where I have this scenario I never have done before.
10 isolation rooms being serve for a dedicated AHU. All air supplied into the rooms must be exhausted out of building. Min of 12 ACH. Negative Pressure to the adjacent area. (ASHRAE 170).
Since all...
Hi,
I've a question about ASHRAE 170.(table 7-1 design Parameter).When it say:
"All room air exhausted directly to outdoor" and at the same time say "Minimum outdoor ach"..my doubt is, if they are establishing a "min outdoor ach". Dose it means that return air is allowed.
For example...
