A ventilation system for ventilation of an aircraft area includes a ram-air duct with an air inlet, a first ram-air duct branch and a second ram-air duct branch parallel to the first ram-air duct branch. A supply line connected to the ram-air duct is adapted to supply air flowing through the ram-air duct to the aircraft area to be ventilated. In the first ram-air duct branch a conveying device is arranged. In the second ram-air duct branch a heat exchanger of an aircraft system to be supplied with cooling energy is arranged. The ventilation system provides ventilation to the aircraft area during ground operation without requiring the conveying device to flow air through the heat exchanger.
