The invention provides an anti-freezing ventilation system and method for a ship in an ice region, and the system comprises a cabin air inlet duct which is sequentially provided with a first air inlet shutter, a cabin air feeder, a first air brake, a first temperature sensor and a cabin air supply outlet in the airflow direction; the mixed air supply duct is sequentially provided with a second air inlet shutter, a mixed air feeder and a first remote control air brake in the airflow direction; the generator smoke exhaust pipe main pipe is provided with a first waste gas heat exchanger; the mixed air supply duct is in heat exchange connection with the first waste gas heat exchanger, and an outlet of the mixed air supply duct communicates with the cabin air inlet duct between the first temperature sensor and the first air brake. Exhaust gas on the ship is used for heating ventilation of rooms such as the cabin chamber and the equipment chamber, and on the premise that the requirement for the ventilation temperature of the cabin chamber and the equipment chamber of ice navigation is met, ship electric power and fuel are saved.
