Air conditioning device for buses

摘要

The device consists of a casing (22), a unit (42) to control the airflow, and a climatising unit (30) that has a heat exchanger (34 + 36) and a fan (32). It also has an outlet (60) for used air. When fresh air goes through the climatising unit, the airflow control leads at least part of the used air that comes from the inlet (52) for returning air through this outlet. The air flow controlling unit is a mechanism of one or more flaps that can be moved into different positions by a single actuating unit (66). The inlet for fresh air (48) and the used air outlet are next to each other. On each side of the roof's middle line of one of the air conditioning devices is positioned. They are installed as independent units.
