Incorrect Ventilation Concept
Mouse over the animated picture above to see messages which are referenced in more detail below.
Pressure relationships between rooms is designated at the bottom of each room (with a plus for positive and minus for negative pressure).
- [CONSTRUCTION ROOM]: Someone doesn’t understand pressurization
concepts. Construction workers thought they were providing good
ventilation by putting a large fan in the window BLOWING FRESH AIR INTO THE
CONSTRUCTION AREA. What is this doing? It is
pressurizing the construction area, forcing the construction contaminants
into surrounding spaces and through the return air stream to other parts of
the building. Everyone in the building will be complaining.
- [OFFICE]: Since the construction room is under positive pressure relative to the surrounding spaces, contaminants flow into the office area. Construction pollutants are also contaminating the return air and are being recirculated to all spaces served by this air handling unit.
