The invention relates to a positive and negative pressure rapid switching control system and method for a ship cabin, and the system and the method are technically characterized in that the positive and negative pressure rapid switching control system for the ship cabin is built, thereby achieving the building of a positive pressure environment and a negative pressure environment of a specific region of the ship cabin, and the automatic and rapid switching between the positive and negative pressures. By utilizing the characteristic that the air supply amount of the variable-frequency air feeder changes along with the working frequency, the requirements of different area areas and air exchange times can be met, one set of system can meet the requirements of various rooms, universality is achieved, and the design workload is greatly reduced. By adjusting the exhaust air rate of the variable-frequency exhaust fan, pressure control over a specific area is achieved, the previous adjusting mode that a fixed-frequen
