The invention relates to a positive and negative pressure environment control system and method for a ship cabin, and belongs to the technical field of ship auxiliary engines. The system comprises a safety cabin unit, an air inlet pipe unit, an air exhaust pipe unit, a positive and negative pressure pipeline unit and a positive and negative pressure control unit; the air inlet pipe unit is used for introducing and processing air in the external atmospheric environment and then conveying the air to the safety cabin unit, and the air exhaust pipe unit is used for exhausting the air in the safety cabin unit to the external atmospheric environment; the positive and negative pressure pipeline unit comprises a first positive pressure environment control branch connected with the air inlet air pipe unit and a second negative pressure environment control branch connected with the air exhaust air pipe unit so as to maintain the positive pressure or negative pressure environment of the safety cabin unit under special conditions. High-pressure gas can be used as a standby power source to drive the positive and negative pressure environment control system of the ship cabin, and it can be guaranteed that the safe cabin unit maintains set positive pressure or negative pressure gradient control.
本发明涉及一种船舶舱室正负压环控系统及方法,属于船舶辅机技术领域,其包括安全舱室单元、进风风管单元、排风风管单元、正负压管路单元和正负压控制单元,进风风管单元用于将外界大气环境中的空气引入并处理后输送至安全舱室单元,排风风管单元用于将安全舱室单元内的空气排出至外界大气环境;正负压管路单元包括连接进风风管单元的第一正压环控支路和连接排风风管单元的第二负压环控支路,以在特殊情况下维持安全舱室单元的正压或负压环境。本发明能够利用高压气体作为备用动力源,驱动船舶舱室正负压环控系统,有利于保证安全舱室单元维持设定正压或负压压力梯度控制。
