The invention discloses a ventilation system and method for an isolation cabin adjusted to be negative pressure. The ventilation system comprises at least one ventilation unit, and each ventilation unit comprises a pressure detection meter, a flow detection meter, an air inlet structure, an air return structure and an air exhaust structure; an FCU system is connected between the air inlet structure and the air return structure; the air return structure comprises an air return pipeline and a filter box; when the ventilation method is implemented, the normal ventilation mode and the negative pressure ventilation mode are mutually switched in the working process, normal ventilation is conducted under the normal condition, the protection function is started under the emergency condition, the isolation cabin is adjusted to be the negative pressure isolation cabin, viruses are prevented from entering the cabin, the exhaust structure is communicated with the external environment of the isolation cabin, and air containing the viruses in the cabin is exhausted. The isolation cabin is clean and ventilated under the conventional condition, the isolation protection function is rapidly started under the emergency condition, the ventilation speed of the isolation cabin is increased, the cabin body of the isolation cabin is changed into negative pressure, and the risk of epidemic situation cross infection in the sailing process of a ship is avoided.
本发明公开了一种调节为负压的隔离舱的通风系统及通风方法,通风系统包括至少一个通风单元,通风单元包括压力检测表、流量检测表、进风结构、回风结构和排风结构;进风结构和回风结构之间连接有FCU系统;回风结构包括回风管路和过滤箱;本发明的通风方法在实施时,正常通风与负压通风两种模式在工作中相互切换,常规情况下正常通风,应急情况下启动防护功能,将隔离舱调节为负压隔离舱,防止病毒进入舱室,排风结构与隔离舱外部环境连通,将舱室内含病毒的空气排出。本发明的隔离舱在常规情况下清洁通风,应急情况下迅速启动隔离防护功能,加大了隔离舱的通风速度,使隔离舱的舱室变为负压,避免了船舶在航行途中出现疫情交叉传染风险。
