Positive pressure air supply system and control method
TLDR
In this article, a positive pressure air supply system and a control method for a building with a fire control signal is described. But the system is in communication connection with a building or other control systems, and detection and control are convenient.Abstract:
The invention discloses a positive pressure air supply system and a control method The system comprises a positive pressure air supplying machine, an intelligent control unit and n air supply units of the same structure The method comprises the steps that the elevator front chamber pressure and the staircase pressure are set through the intelligent control unit; during pressurization air supply, the air pressure of a staircase is larger than the air pressure of the elevator front chamber, and the air pressure of the elevator front chamber is larger than the air pressure of an aisle; when a fire control signal exists, a positive pressure air supply machine is controlled to work, the difference value between a detection pressure numerical value of a staircase pressure sensor and the barometric pressure is obtained through the intelligent control unit, and the maximum value of the difference value is taken as a reference signal to be compared with the staircase pressure set value, so that the opening degree of an electric bypass pressure-relief valve is adjusted to enable the actually-detected staircase pressure value to approach to the set value; and when the fire control signal is eliminated, the intelligent control unit controls the positive pressure air supplying machine to stop working The system is in communication connection with a building or other control systems, and detection and control are convenientread more
