Room positive pressure
Hi Everyone,
Could anyone help me or recommend me some literature about room pressurization methods and how to design proper the ventilation system to achieve a positive pressure in a room?
I know the leakage area is the main mechanical parameter in the pressurization system, but I have some doubts about the entire process.
For instance: I have a room with a determined volume, a determined airflow by the AHU unit based in the sensible heat load inside the room.
Some doubts comes up:
- What the airflow to be introduced in the room to pressurize it to a determined pressure value (Pa)?
- If the room is at negative pressure, what the common possible reasons for this?
Thanks in advance everyone

Here's a starter, it is not a simple process. The designer should specify everything for the contractor.
