Abstract

The invention relates to a ram air duct for an aeroplane air conditioning system having an inlet channel which can be closed by an inlet valve and in which at least one heat exchanger is arranged, having a blower arranged in a blower chamber and an outlet passage closable by an outlet valve. In accordance with the invention, the outlet passage is divided into two separately extending passages of which one is guided as a blower outlet passage up to the blower into the blower chamber and the other is designed as a bypass passage. The outlet valve only closes the bypass passage in the closed state.
