A combination of a roof top air conditioning unit, the combination comprising a roof top unit, a roof, connection air ducts and an air distribution box, wherein the roof top unit is disposed on an outer wall surface of the roof, the roof top unit having a base pan provided with an air outlet; the air distribution box disposed on an inner wall surface of the roof, the air distribution box provided with an air inlet upper duct; the plurality of connection air ducts communicating the air outlet of the roof top unit with the air inlet upper duct of the air distribution box via the opening of the roof, characterized in that an adjustment portion for adjusting a roof thickness gap is provided around the air outlet of the base pan. This combination simplifies the complexity of assembly, such that the mounting process is simpler, and thus the cost is also reduced.

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.

Present embodiments relate to a heating, ventilation, air conditioning (“HVAC”) system which is used in both fixed and mobile structures, and which has a luminaire disposed in the HVAC to provide illumination therefrom. The luminaire may be a single continuously on light or it may be a flashing light with one or more patterns. The light may emit a single color or multiple colors. The light may also have a flashing sequence which corresponds to audio. The light may be wired to a switch and/or may be controlled by a smart device in wireless communication with the HVAC system.

To improve a view of a side area from a cabin, the cabin mounted on a machine body includes a hollow rear pillar located on a rear portion of a side surface of the cabin. The rear pillar includes an interior opening through which an interior of the rear pillar is communicated with an interior of the cabin, and an exterior opening through which the interior of the rear pillar is communicated with an exterior of the cabin.

An air conditioner, vent or like mountable structure on the roof of a recreational vehicle, which allows for movement of wires from an alternate exterior appliance from the exterior to the interior of the recreational vehicle through the mountable structure. The structure has one or more connection ports located to allow for connection of external wires to move to the interior of the vehicle.

An air-conditioner, adapted to be fitted to a roof/wall of a vehicle, comprises: an external unit containing a compressor and at least one heat exchanger element and having air channels respectively for supplying conditioned air and for receiving return air through an opening in a roof or wall of the vehicle, the opening being either of two types of different sizes; a frame to be installed in the opening and between the external unit and the roof/wall and having locating elements, on each of two opposite sides of the frame, configured to locate the frame in the opening and to locate the frame in the external unit, wherein the frame is to be installed with the first side facing the roof or wall for the first type of opening and is to be installed with the first side facing the external unit for the second type of opening.

A modular, roof-mounted air-conditioning system for a vehicle includes at least two similar air-conditioning modules for air-conditioning areas within the vehicle, wherein the air-conditioning modules are combined to form a functional assembly, and wherein the assembly can be installed on a roof of the vehicle.

A sports car provided with a conditioning system comprising a conditioning device for treating environmental air, an internal channel for delivering conditioned air generated by said conditioning device throughout a vehicle cockpit, wherein said conditioning device is arranged at the rear of said vehicle cockpit.

The invention relates to a multi-zone air conditioning system for vehicles (1) with several air conditioning zones (2), in particular for buses, characterized thereby that an air temperature control unit (3) is implemented to generate simultaneously warm air and cold air, wherein the cold air across a cold air duct (5) and the warm air across a warm air duct (6) extend separated from one another as a double conduit over the length of the vehicle (1) and that decentralized air mixing units (4) with at least one air outlet (20) are disposed along the double conduit and that the air outlets (20) are assigned to the air conditioning zones (2) of the vehicle (1).

An agricultural vehicle has an operator environment with a roof portion, and an air treatment apparatus installed within the roof portion. The air treatment apparatus includes a vehicle HVAC system having an inlet plenum, other HVAC components and an outlet to the operator environment. The air treatment apparatus further includes an air filtration system having at least one external inlet and first and second filtration devices located between the external inlet and the HVAC inlet plenum. The roof portion is a hollow structure having upper and lower surfaces and front, rear, left and right sidewalls, and the first and second air filtration devices are disposed along one of the left and right sidewalls within the hollow structure of the roof portion. The HVAC system is preferably disposed along the rear sidewall within the hollow structure of the roof portion.
