Abstract: An air conditioning system has a fan configured for generating an airflow in a predetermined direction. The system includes a heat exchanger assembly configured for being crossed by the airflow for exchanging heat in a controlled manner. An air outlet is located downstream of the heat exchanger assembly and configured for delivering the airflow. The heat exchanger assembly includes an evaporator having a back surface or side facing towards the air outlet and configured for being crossed by the cooled airflow. The system also includes a droplet separator located downstream of and in proximity to the back surface or side. The droplet separator is configured for deviating droplets of water vapor condensed on the back surface or side, so as to prevent the down flow of the droplets of water vapor towards the air outlet.

Abstract: Cabin air treatment apparatus for an agricultural machine, comprising at least an external air inlet, a filtration system, an HVAC system, and a cabin air supply outlet. The apparatus further comprises a hermetically closed box inside which the HVAC system is housed, the box having a levelling opening for placing the box into communication with a cabin of the agricultural machine to level a pressure inside the box with a pressure inside the cabin. The filtration system comprises a filter for effecting a filtration of at least one among dust, aerosols and vapours, arranged at an external air inlet formed on the box, and an air inlet duct arranged downstream of the filter and provided with a selecting valve having a first outlet connected to the HVAC system, and a second outlet connected to a fan of a condensation system, through a cleaning duct.

Abstract: A roof assembly for a vehicle cabin, particularly for the cabin of an agricultural machine, comprising a housing of plastic material and an air conditioning unit housed within the housing, and at least one air inlet fluidically connected to the air conditioning unit and arranged at a periphery of the housing, and a filter arranged downstream of the air inlet. An air inlet shield is arranged at the air inlet, said air inlet shield being mounted to the periphery of the housing and sealingly mounted to the air inlet, the air inlet shield comprising a pair of shaped plates of plastic material, peripherally welded to each other, between which a chamber fluidically communicating with the filter and with the outside of the roof assembly is defined.

Abstract: Cabin air treatment apparatus for an agricultural machine, comprising at least an external air inlet (11, 16), a filtration system (20), an HVAC system (30), and a cabin air supply outlet (40). The apparatus further comprises a hermetically closed box (1) inside which the HVAC system (30) is housed, the box having a levelling opening (60) for placing the box (1) into communication with a cabin (C) of the agricultural machine to level a pressure inside the box (1) with a pressure inside the cabin (C), wherein said at least one external air inlet comprises a first external air inlet (11) formed on the box (1). The filtration system comprises a first filter (21) for effecting a filtration of at least one among dust, aerosols and vapours, arranged at the first air inlet (11), and a blower (22) for drawing air from the first air inlet (11) and delivering it to the HVAC system (30), said blower being arranged directly connected downstream of the first filter (21) and inside the box (1).

Abstract: A heat exchanger for heat exchange between air and a heat exchange medium includes a plurality of heat transfer conduits arranged parallel to each other as flow paths for the heat exchange medium and a plurality of fin members. The fin members are configured to provide: an air inlet end for air inflow, an air outlet end for air outflow, and an air flow path. The air flow path connects the air inlet end with the air outlet end and allows a heat exchange with the plurality of heat transfer conduits. Each fin member includes a plurality of undulation troughs coplanar with each other and connected together so as to define a water condensate flow path. Each water condensate flow path has a flat bottom which extends from the air inlet end to the air outlet end.
