Ship ventilation system and control method thereof

The invention provides a ship ventilation system and a control method thereof.The ventilation system comprises a dehumidifier, an air supply system, an air return system, a sensor system and a controller, the sensor system monitors the internal environment of a ship tank cabin and transmits monitored data to the controller, the controller controls the dehumidifier, and the dehumidifier controls the air supply system and the air return system. Therefore, the air quantity and cold quantity or heat quantity in the tank cabin are adjusted. The factors influencing the air volume and the humidity are monitored in real time, so that the air volume and the humidity in the tank cabin are adjusted and controlled in real time, the construction state of the tank cabin is good, the ventilation requirements of personnel and equipment are met, the environment-friendly and energy-saving effects are considered, and the construction cost is effectively reduced. 本发明提供一种船舶通风系统及其控制方法，通风系统包括除湿机、送风系统、回风系统、传感器系统和控制器，传感器系统对船舶罐舱内部环境进行
