Room Pressure 2

[sarsets]

Hello,
Please can you help me, I have a room 2,2m x 2,3m x 2,55 and I need it to be pressurized to 15 Pascals, the volume of the room would be 12.9 or say 13 Cubic m

I TAKE 10 CFM FOR 1 m2 OF FLOOR + 150 CFM FOR EACH DOOR IN THE ROOM.
THIS IS THE OUTDOOR AIR.
YOU MUST ALSO SEAL THE CEILING AND CRACKS WITH SIKA OR SILICONE.
IF YOU HAVE SUCTION AIR FROM THE ROOM ADD IT TO THE FRESH AIR.
ALSO NOTTICE THAT THE DOORS ARE OPENED TO THE ROOM AND NOT OPENED TO THE OUTSIDE OF THE ROOM BECAUSE , SO THE HIGH PRESSURE WILL "CLOSE" THE DOOR AND NOT "OPEN" IT (IN THIS CASE AIR WILL RUN AWAY FROM THE DOOR
