Abstract: A roof of a cab comprising a load-bearing structure made of plastic material, and a heat exchange assembly for treating an airflow, the heat exchange assembly being borne by the structure made of plastic material and comprising at least one heat exchanger and at least one ventilation unit. The load bearing structure comprises a central section in which is housed the heat exchange assembly and in which is defined a chamber for collecting the treated airflow. The load bearing structure further comprises a central section for the distribution of the treated airflow towards the interior of the cab, the annular channel surrounding the central section and communicating with the collection chamber.

Abstract: Roof of a cab, in particular for an agricultural machine, comprising a load-bearing structure made of plastic material, and a heat exchange assembly for treating an airflow, the heat exchange assembly being borne by the structure made of plastic material and comprising at least one heat exchanger and at least one ventilation unit. The load bearing structure comprises a central section in which is housed the heat exchange assembly and in which is defined a chamber for collecting the treated airflow. The load bearing structure further comprises a central section for the distribution of the treated airflow towards the interior of the cab, the annular channel surrounding said central section and communicating with said collection chamber.
