An air-conditioning apparatus includes a casing to store a device included in the air-conditioning apparatus, and an access door pivotably supported by the casing via a hinge so as to be pulled downward of the casing to allow access from inside a compartment of the railway vehicle to the device in the casing. A control device to control the air-conditioning apparatus and an inverter device to supply an operational electric current to the air-conditioning apparatus are mounted on a surface of the access door on a side facing an interior space of the casing. Main circuit wiring for supply of power and control wiring for sending and receiving of a control signal are disposed apart from each other, with the access door between the main circuit wiring and the control wiring.

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 exterior 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 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.

Example embodiments relate to an air conditioning unit for installation on a roof, including a housing, an indoor air distributor, and two frame units. The two frame units are of identical design and each have a first side and a second side. In an installed state, the two frame units are arranged between the housing and the indoor air distributor and serve as an upper frame unit and a lower frame unit, respectively. The first sides face each other, the second side of the upper frame unit faces the housing, and the second side of the lower frame unit faces the indoor air distributor.

The present invention relates to a component part of a climatization system or window system for a recreational vehicle, the component part covers a mounting frame of the climatization system or window system and the component part is selected from an air distribution unit that is configured to distribute air inside the recreational vehicle, a decorative window frame and a shading unit for adjusting the amount of incident light, the component part has one or more attachment portions which, in a mounted state, are accessible by the user from inside the recreational vehicle, wherein each of the one or more attachment portions is either connectable to one particular module or to a plurality of different modules in a mutually exchangeable manner, and wherein the modules include sensors for detecting events or parameter changes inside the recreational vehicle or emitting devices for emitting light or sound.

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.

A modular climatization system for a recreational vehicle and includes a mounting frame and a window, the mounting frame is mountable into a roof cut-out of the recreational vehicle, thereby defining an opening in the roof, an outward facing side and an inward facing side of the mounting frame with respect to the recreational vehicle, and the window is mountable to the outward facing side of the mounting frame, the modular climatization system further comprises an air conditioning unit and an air distribution unit, the air conditioning unit being mountable to the outward facing side of the mounting frame, wherein the window and the air conditioning unit are mountable to the frame in a mutually exchangeable manner, and the air distribution unit being mountable to the inward facing side of the mounting frame.

A roof air conditioner includes a blower configured to allow air to be introduced into a housing, a first flow path configured to allow the air in the housing to be discharged through a first discharge port, an evaporator located in at least a part of the first flow path, a second flow path configured to allow the air in the housing to be discharged through a second discharge port, and a switching door configured to open and close the first discharge port and the second flow path. The first flow path includes a cooling flow path discharging the air through the first discharge port via the evaporator, a bypass flow path discharging the air through the first discharge port without passing through the evaporator, and a temp door controlling an opening amount of the cooling flow path and an opening amount of the bypass flow path.

A dual inverter two-cycle roof mounted air conditioning system for a motorized vehicle may form a first cooling cycle of a built-in inverter type first compressor and first evaporator and a second cooling cycle of a built-in inverter type second compressor and second evaporator as independent two-directional refrigerant paths in a state in which one condenser is installed in the internal space of an air conditioner case as a single core condenser. This secures required cooling performance using a miniaturized dual compressor and reduces the inverter capacity using the power topology of a miniaturized dual inverter.

A vehicle roof, in particular for a passenger car, the vehicle roof having a one-part or multi-part roof skin, at least one environment sensor for detecting a vehicle environment, the environment sensor being disposed below the roof skin and being able to detect the vehicle environment through a sensor see-through area of the roof skin, and a cooling feature for cooling the environment sensor, at least part of the cooling feature being disposed in a wet area, and the environment sensor being disposed in the wet area.

A compartment has an air-conditioning assembly for supplying supply air into the compartment and drawing indoor air as extract air out of the compartment. The air-conditioning assembly is configured so that a portion of the extract air is discharged as exhaust air and another portion of the extract air is returned to the compartment as recirculation air, which is mixed with outdoor air drawn from the outside of the compartment and supplied as supply air. The air-conditioning assembly includes an air-conditioning unit and an air guiding means. The air-conditioning unit includes a housing having an ambient air inlet and a heat exchanger located inside the housing. The air guiding means is used for guiding the exhaust air from the compartment to a space inside the housing between the ambient air inlet and the heat exchanger for mixing the exhaust air with an ambient air from outside the compartment.
