We are using stair case pressurization system in one of our sub station project. The capacity of fan is calculated by assumimg that one door(ground floor-opening outwards) is opend and the other door (first floor-opening inwards) closed and to maintain 15 pa inside the stairwell. But when both doors are closed pressure is building up inside the space and we are facing difficulty in opening the first floor door. How can we design a relief damper to maintain a pressure of 50 pa inside thee stairwell when both door are closed.
