The embodiment of the invention discloses a pressurized air ventilation method which is applied to a ship and comprises the following steps: if a feedback signal that the concentration of toxic gas detected by a gas detector reaches a set value is received, respectively sending a first control signal and a second control signal to an air conditioning system and an air pressurization system; the air conditioning system cuts off system operation based on the first control signal, and closes corresponding valves in an exhaust subsystem, a fresh air subsystem, an air supply pipeline and an air return pipeline in the air conditioning system; the air pressurization system releases air from the air storage tank based on the second control signal, and after the released air sequentially passes through the first-stage pressure reducing valve and the second-stage pressure reducing valve to be reduced to the pressure for use, the electromagnetic control valve in the area where the related personnel are detected in the ship is opened, and air is released to the area where the related personnel exist. After the system detects poisonous gas, the air pressurization system reduces the pressure of high-pressure air to the bearable degree of people through a pipeline and releases the high-pressure air to each area.
本发明实施例公开了一种加压空气通风方法,应用于船舶,方法包括:若接收到气体探测器探测到有毒气体浓度达到设定值的反馈信号,则分别向空调系统和空气加压系统分别发送第一控制信号和第二控制信号;空调系统基于第一控制信号切断系统运行,并关闭空调系统中的排风子系统、新风子系统、送风管路以及回风管路中的相应阀门;空气加压系统基于第二控制信号从空气储存罐中释放空气,在释放的空气依次通过一级降压阀和二级降压阀降到供使用的压力后,打开船舶中检测到存在相关人员的区域的电磁控制阀,向存在相关人员的区域释放空气。其在系统探测到有毒气体后,空气加压系统通过管路将高压空气降压到人们可以承受的程度释放到每个区域中。
