One aim is to provide a technique allowing a device to be cooled without being housed inside a duct. A device module includes: a support member that is disposed in a roof inner space that is located between a roof panel and an interior member in a vehicle; and a device that is supported by a support surface among outer surfaces of the support member. A support-member-side flow path is formed inside the support member, and the support-member-side flow path is connected to a duct-side flow path in a duct in the vehicle.

A car roof automatic HVAC apparatus disposed within a roof of an automobile to maintain a more comfortable temperature inside of the automobile for a driver to return to, and to act as a safety mechanism to prevent a child or pet left inside the automobile from dying of excessive heat or cold. A plurality of vents has a plurality of fans disposed within, and a heater allows the fans to blow hot air when needed. A first CPU, the heater, a light, the plurality of vents, and the plurality of fans are powered by a rechargeable battery or an alternate power source. A remote control can be used to operate the car roof automatic HVAC apparatus. An automobile interface unit disposed within the automobile can detect when the vehicle has been turned off for a programmed amount of time to automatically begin ventilation or heating.

A cab of an agricultural vehicle has having a seat for an operator and a console unit arranged forward of the seat for housing an instrument display. The cab is fitted with an HVAC system comprising a heat exchanger unit located within the console unit and a blower located on the floor of the cab beneath or adjacent the seat and serving to blow air by way of a floor-level duct to the heat exchanger unit.

The skylight vent cover is installed immediately beneath the existing skylight in the ceiling of a structure, e.g., motorhomes, cabin boats, etc. The vent cover includes one or more opaque panels that are spaced away from the overlying structure to substantially block light passage while allowing airflow between the panel(s) and overlying structure. Some embodiments have a single planar or non-planar panel. Other embodiments have a plurality of tiered panels. The upper surface(s) of the panel(s) can have a reflective coating thereon to reflect light and heat from the skylight and vent. Various attachments can be provided, e.g., mating hook and loop material, magnets, hinge and latch, etc. In all embodiments, the panel is spaced away from the overlying ceiling structure, and in the case of multiple panel embodiments, the panels are spaced apart from one another to provide good ventilation and airflow therebetween.

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.

A vehicle roof fan for providing air conditioning to a user of a vehicle. The vehicle roof fan may include a plurality of individually controlled fans. The apparatus includes power management features to limit the power consumption, such as a user presence detector and/or battery threshold monitoring. The plurality of fans may be associated with one or more optical sensors that each control the operation of one or more of the fans based upon the presence of a user. The air conditioning apparatus may also include heating and/or cooling components to modify the air temperature from the apparatus.

An air vent for a vehicle or vehicle canopy includes an external and an internal duct. The external duct has an inlet and an outlet. The height of the outlet is less than that of the inlet. The inlet and the outlet are arranged such that, in use, an uppermost point of the inlet is located above an uppermost point of the outlet. The internal duct is in fluid communication with the external duct via one or more openings arranged in the internal duct or at a junction between the internal duct and the external duct. The internal duct is configured to be in fluid communication with an interior of the vehicle via a slot defined by the vehicle. The or each opening is arranged such that, in use, the uppermost point of the outlet of the external duct is located below a lowermost point of the or each opening.

Rooflight or window 1 for vehicles, particularly for a recreational vehicle, comprising a window frame 2, the window frame 2 comprises a ventilation path allowing air exchange between the inside and the outside of the vehicle, wherein the window frame 2 comprises ventilation slots 4, 5 at least at a surface 8 of the window frame 2 facing the inside of the vehicle, wherein the rooflight or window 1 further comprises a cover 3 being connected to the window frame 2 and covering the surface 8 of the window frame 2 facing the inside of the vehicle, wherein along the outer edge of the window frame 2 a circumferential gap 9 is present between the window frame 2 and the cover 3 functioning as a canal for ventilation air.

A vent shade assembly for a recreational vehicle ceiling vent comprises a vent shade outer frame having an inner flange, a vent shade inner frame having an inner flange, and a pair of side walls disposed between the inner flange of each of the outer and inner frame to form a slot. A movable pleated shade element disposed within the slot is operable between a closed position and a plurality of positions there between. A first and a second shade string is disposed at least partially alongside and parallel to a first and second of the pair of side walls, respectively, and proximate a first and a second side edge of the movable pleated shade element, respectively. A portion of the inner flange of the vent shade outer frame supports the first and second side edge of the movable pleated shade element.

A cab of an agricultural vehicle has having a seat for an operator and a console unit arranged forward of the seat for housing an instrument display. The cab is fitted with an HVAC system comprising a heat exchanger unit located within the console unit and a blower located on the floor of the cab beneath or adjacent the seat and serving to blow air by way of a floor-level duct to the heat exchanger unit.
