Abstract

The invention relates to the technical field of fire extinguishment for buildings, in particular to a pressure relief well. The pressure relief well comprises a main pressure relief well body for forming a pressure relief well cavity; the main pressure relief well body comprises an indoor part arranged in the building indoor space and an outdoor part bulging out of the roof of the building from the indoor part; the indoor part comprises one or more pressure relief ports communicating with the pressure relief well cavity and the building indoor space; the outdoor part comprises an exhaust port communicating with the pressure relief well cavity and the building outdoor space; and a normally-closed smoke discharging fire damper is mounted on each pressure relief port. With the pressure relief well, the outer wall structure of the building can be complete and reliable while gas fire-extinguishment and pressure relief in a protection zone is realized, and the appearance is better. Besides, with the pressure relief well, the indoor temperature control effect by the aid of an air conditioner cannot be affected, temperature control by the aid of the air conditioner is more energy-saving and efficient, the cleanliness of the indoor environment is guaranteed, and the service life of indoor equipment or products can be prolonged.

Description

technical field

[0001] The invention relates to the technical field of building gas fire extinguishing, in particular to a pressure relief well and a building. Background technique

[0002] At present, in the construction of large-scale data computer rooms, the protection area of ​​the main computer room is usually protected by a gas fire extinguishing system, especially a heptafluoropropane gas fire extinguishing system. Considering that after the gas is released, the pressure in the protected area will increase instantaneously, and this instantaneous pressurization may destroy the building envelope in the protected area, so it is necessary to set up a pressure relief port for reducing the air pressure in the protected area to ensure The building enclosure structure in the protection area of ​​the gas fire extinguishing system is safe and reliable, and can successfully extinguish the fire quickly and in time.

[0003] The existing pressure relief port is usually directly s...
