Standard of Execution
China National Standard GB50016-2014 "Code for Fire Protection of Building Design"
China National Standard GB51251-2017 "Technical Standard for Smoke and Smoke Exhaust System in Buildings" Article 3.4.4: The mechanical pressure supply air volume should meet the increasing pressure distribution from the corridor to the ante-room to the stairwell, and the excess pressure value should comply with the following regulations:
(1) The pressure difference between the antechamber, enclosed refuge (room), and corridors is 25Pa to 30Pa.
(2) The pressure difference between the stairwell and corridor is 40Pa to 50Pa.
(3) When the system's remaining pressure exceeds the permissible pressure difference, depressurization measures should be taken.
(4) Mechanical pressure-air supply systems should be equipped with pressure measurement devices and air pressure regulation measures.
