A vehicle including a roof that separates an exterior and an interior of the vehicle, and an air conditioning system. The roof has an exterior surface, an interior surface, and an aperture extending through the roof between the exterior surface and the interior surface. The air conditioning system includes an exterior housing that is mounted to the exterior surface of the roof and includes a divider defining a first cavity, and a second cavity. The air conditioning system also includes a condenser, an evaporator, and an evaporator blower. The air conditioning system further includes an interior housing that is removably mounted to the interior surface of the roof and defines a mounted position and a removed position in which the evaporator and evaporator blower are accessible for servicing from the interior of the vehicle.

A device for temperature control for a motor vehicle, includes a diffractive optical element disposed on a surface of the motor vehicle, and a radiator. The diffractive optical element couples in incident radiation and conducts the coupled-in incident radiation away from an area of the motor vehicle to be cooled. The radiator includes an absorber to absorb the coupled-in incident radiation which is conducted to the absorber from the diffractive optical element. The radiator releases energy based on the coupled-in incident radiation absorbed by the absorber.

A vent cover apparatus for protecting vents, air conditioners, and skylights includes a cover body having a body front side, a body back side, a body left side, a body right side, a body top side, and an open body bottom side. The body bottom side is configured to receive a vent, an air conditioner, or a skylight on a roof of a recreational vehicle or a building. The cover body is rigid and allows for full air flow through the cover body. A plurality of mounting braces is coupled to the cover body. Each mounting brace is coupled adjacent the body bottom side and configured to engage the roof of the vehicle.

An air-conditioner casing for an air conditioner mounted on a ceiling of a bus are provided. The air-conditioner casing includes: a pair of bases having first and second bases which are installed to be spaced apart from and opposite to each other; and one or more shrouds coupled in a space between the first and second bases, in which the number of shrouds to be connected and installed in the casing may be determined based on a capacity of an air conditioner.

A working vehicle includes a cabin and an outside air inlet portion. The working vehicle further includes: a filter device having: a first filter providing a first filtering level; and a second filter providing a second filtering level that is a filtering level higher than the first filtering level; an air conditioning unit to which the outside air having passed through the filter device is supplied; and a filter changing mechanism having: a first state to allow the outside air to pass through only the first filter; and a second state to allow the outside air to pass through at least the second filter among the first filter and the second filter, the filter changing mechanism being configured to be selectively switched to the first state or the second state.

An air conditioning unit, including: a chamber; a fan, in the chamber, for effecting an entry air entering the chamber and an exit air exiting the chamber; and an evaporative unit, in the chamber, for conditioning the entry air; wherein the fan, together with at least part of the chamber, creates a pressure zone, without ejecting air directly to, or without drawing air directly from, the evaporative unit, such that air moves through the evaporative unit substantially through a pressure effect.

An air-conditioning unit for installation on a roof is disclosed. The air-conditioning unit includes a plurality of functional components arranged in a housing which has an attachment side for installation, and two support arms which support at least one functional component such that the at least one functional component is arranged higher with respect to the attachment side than other functional components. The two support arms laterally encompass the at least one functional component so that each support arm supports a different side of the at least one functional component, in that the two support arms each support the at least one functional component in an area of a face side, in that the two support arms each have the shape of a “S”, and in that each support arm has two face side portions which are positioned at different heights, and a portion connecting the two face side portions.

An air treatment system for an agricultural vehicle includes an air filtration apparatus having an air filter housing for receiving an air filter cartridge and downstream air processing apparatus fluidly connected with the air filter housing by a duct. The system can receive first and second type air filter cartridges having corresponding first and second outlet sealing configurations. The duct has inner and outer conduits that define an inner flow path and an outer flow path. A filter sealing arrangement of the duct can engage with either type of filter cartridge. This enables two different types of filter cartridge, which may be configured to provide different levels of filtration, to be selectively mounted to the system in the same housing. Air flow may be restricted to the inner flow path when one type of air filter cartridge is fitted.

Vehicles and methods for cooling a cabin using a cold roof of the vehicle are provided. The vehicle includes a roof, a cabin, and an insulation layer disposed between the roof and the cabin. The vehicle also includes a passage that fluidly couples the roof with the cabin. The passage is switchable between an open mode and a closed mode. The passage is switched between the open mode and the closed mode depending on a relationship between a roof temperature, a cabin temperature, and/or a threshold temperature. The passage may be formed through the insulation layer or extend outside of the insulation layer fluidly coupling the roof with the cabin.

An air distribution system for use in a cargo delivery vehicle. The air distribution system includes a compressor, a condenser, a plurality of tubes, an air distribution unit, and a mounting system for mounting the air distribution unit to the roof of the cargo delivery vehicle. The air distribution unit includes a unit body, a vent hood, and a vent plate. The unit body includes a fan and a plurality of tubes. The vent plate includes at least one vent opening.
