An air conditioning system for mounting on a vehicle roof includes a condenser module and an evaporator module. The condensor module includes an inlet for receiving a compressed fluid, a heat exchanger for condensing the fluid and transferring heat from the fluid, and an outlet for releasing the condensed fluid. The evaporator module includes a deformable base for placement on the roof, that conforms to the roof's curvature. The evaporator module also includes an inlet receiving the cooled condensed fluid from the condensor outlet, an expansion valve for vaporizing the fluid, a heat exchanger for transferring heat to the vaporized fluid, and an outlet for returning the heated vaporized fluid to the condenser module via a compressor. The evaporator module also includes an interchangeable end plate connected to an end of the base, which maintains the base in a shape that conforms to the curvature of the roof.

Overhead passenger comfort modules are provided with a module segment having a support frame member which includes a perimetrical trim frame member, and a ventilation system supported by the support frame member. The ventilation system includes a supply conduit adapted to being fluid-connected to a supply of ventilation air, and first and second branch conduits fluid-connected at one end to the supply conduit and terminating in elongate first and second ventilation openings at first and second edge regions of the support frame member. First and second concavely curved edge diffuser portions are provided which are adjacently positioned to and spaced from the first and second ventilation openings respectively. Ventilation air discharged from the first and second ventilation openings will therefore impinge on the concavely curved first and second edge diffuser portions so as create a diffused volume of air which envelops substantially a passenger seated therebelow and establish a personal ambient air zone for the passenger.

A vehicle air-conditioning apparatus includes emergency dampers switchable between opening states for opening emergency vents and closing states for closing emergency vents. A control device switches the emergency dampers from the closing states to the opening states while keeping an indoor fan operating, when determining that refrigerant is leaked from a refrigerant circuit on the basis of results of detection by refrigerant leakage detectors. An indoor unit chamber includes supply air guiding sub-chambers for guiding the internal air delivered by the indoor fan to supply openings. The emergency vents are included in the supply air guiding sub-chambers. The indoor fan forms flows of the internal air with the air pressures in the supply air guiding sub-chambers being higher than the atmospheric pressure.

An air conditioner for a recreational vehicle is provided. The air conditioner includes an indoor base panel configured to mount to the ceiling of the recreational vehicle. The indoor base panel includes a first flexible latch on a first side of the indoor base panel and a second flexible latch on a second side of the indoor base panel opposite the first side. The air conditioner also includes an indoor grille removably coupled to the indoor base panel by the first flexible latch and the second flexible latch.

According to some embodiments, a zonal conditioning system for a vehicle comprises a headliner assembly configured to be secured to the top surface of a vehicle interior, wherein the headliner assembly comprises a first side positioned away from the vehicle interior and hidden from the vehicle interior, and a second side positioned toward the vehicle interior, the headliner assembly comprising at least two vents through which air selectively passes. The zonal conditioning system further includes at least two fluid modules positioned along the first side of the headliner assembly, wherein each of the fluid modules comprises a fluid transfer device and an outlet. In some embodiments, at least one property of the air discharged through the first and second vents can be selectively regulated to create separate conditioning zones within the interior of the vehicle.

Various embodiments of a parking cooler are provided which may be operated from battery power, for example during engine off operation. Further, the parking cooler or air conditioning system may have varying cooling capacities based on operating modes in order to maximize performance or maximize battery life. The parking cooler may include one or more condensers and a housing to accommodate such variation of cooling capacity.

A vehicle air conditioning apparatus includes: a refrigerant circuit in which a compressor, a heat source side heat exchanger, an expansion device, and a load side heat exchanger are connected by pipes; and a controller that performs switching between a heating operation in which refrigerant in the refrigerant circuit circulates and a defrosting operation of the heat source side heat exchanger in which the refrigerant in the refrigerant circuit circulates in a direction opposite to a direction in the heating operation. The controller allows an airflow flowing from the load side heat exchanger into a cabin through a first air outlet in the heating operation, and an airflow flowing from the cabin into the load side heat exchanger through the first air outlet is produced in the defrosting operation of the heat source side heat exchanger.

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).

A vehicle air-conditioning apparatus has a duct that is configured to supply an air-conditioned air to a vehicle interior, and has a resinous base layer, and an infrared reflective layer formed on a surface of the resinous base layer facing a vehicle exterior to reflect an infrared ray.

A mobile retail motorized vehicle, having a motorized vehicle which features an exterior compartment mounted on a number of wheels, where the exterior compartment adapted and configured to hold a power source separate from the motorized vehicle power source; an exterior perimeter defined by at least one transparent enclosure and at least one entryway, where the at least one enclosure is defined by a second exterior perimeter. The mobile retail motorized vehicle also has an internal compartment, which has a retail showroom which is configured to display a plurality of merchandise items; and wherein the internal compartment further comprises a plurality of displays; and a solar powered lighting source; and an audio and speaker system.
