A parking cooler which is capable of battery powered operation during engine off operation. The parking cooler or air conditioning system may vary in cooling capacities to maximize cooling or maximize battery life. The parking cooler includes one or more condensers and a housing to accommodate such variation of cooling capacity.

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.

The present embodiments relate to an air distribution apparatus for distributing conditioned airflow from a roof mounted air conditioner to the inside of a vehicle, which includes an inlet port adapted to receive the conditioned airflow from the roof mounted air conditioner. An outlet port, which is disposed adjacent to each longitudinal end of the apparatus, delivers conditioned airflow to the vehicle. An internal supply duct is adapted to evenly split the conditioned airflow to the outlet ports.

A radial fan half-spiral housing has a pressure chamber extending in the circumferential direction about an axial intake opening (5) to a radial blow-out opening (31). The pressure chamber, as viewed in the circumferential direction, is subdivided into at least one beginning portion (7), one central portion (8), and one blow-out portion. The intake opening (5) determines a central axis of rotation for a fan wheel. An averaged half-spiral housing radius, as viewed about the axis of rotation (11), varies in the beginning portion (7), the center portion (8), and the blow-out portion (9). It reaches a maximum in the blow-out portion (9). The center portion (8) of the half-spiral housing radius is reduced in a region determining a maximum height H(δ,z) of the half-spiral housing (1) compared to a logarithmic spiral radius (r.sub.log).

A roof module for forming a motor vehicle roof, the roof module having a panel component whose outer surface at least partially forms a roof skin of the vehicle roof, the roof module having at least one environment sensor configured to send and/or receive electromagnetic signals for detecting the vehicle environment. The environment sensor is disposed below the roof skin formed by the panel component, the roof module having a cooler configured to discharge exhaust heat emitted by the environment sensor and/or heat introduced from outside from the environment sensor.

An air treatment system is described, for a closable room of a vehicle, comprising: an air conditioning device provided with a fan and connectable to the room; an inlet opening for outside air, connected to the air conditioning device; a filtration device for filtering the outside air entering from the inlet opening; a recirculation port; a valve assembly provided with a shutter member, interposed between the inlet opening, the recirculation port and the air conditioning device and movable between a plurality of operating positions, in which it varies the shares of air coming from the inlet opening and the recirculation port; and a control unit to adjust the operating position of the shutter member so as to control the shares of air being drawn from the inlet opening and from the recirculation port and to maintain a predetermined value of overpressure in the room with respect to the outside.

The present embodiments relate to an air distribution apparatus for distributing conditioned airflow from a roof mounted air conditioner to the inside of a vehicle, which includes an inlet port adapted to receive the conditioned airflow from the roof mounted air conditioner. An outlet port, which is disposed adjacent to each longitudinal end of the apparatus, delivers conditioned airflow to the vehicle. An internal supply duct is adapted to evenly split the conditioned airflow to the outlet ports.

A recreational vehicle air conditioner (RVAC) includes a ceiling-mount cover panel and a control box. The control box includes a first box portion and a second box portion. The first box portion is positioned above the ceiling-mount cover panel. The second box portion is connected to the first box portion with a hinge. The second box portion is pivotable between a closed configuration and an open configuration on the hinge. The second box portion is nested with the first box portion in the closed configuration, and the second box portion is pivoted away from the first box portion on the hinge in the open configuration. An electronic control panel is mounted to the second box portion of the control box.

A vehicle roof assembly includes a roof that defines an aperture. A heating, ventilation, and air conditioning assembly is selectively disposed within the aperture. The heating, ventilation, and air conditioning assembly includes a housing defining an interior. The housing defines an intake and a vent opening. The intake is defined on a first side of the housing. A fan is disposed within the interior on a second side of the housing. The second side opposes the first side. A duct is disposed within the interior. The duct extends between the first side and the second side of the housing. The duct fluidly couples the intake with the vent opening.

A system for mixing air for a vehicle HVAC (heating, ventilation, air-conditioning) component, includes a first inlet for outdoor air from an exterior space of the vehicle; a first fan in communication with the first inlet to control (only) an air inflow through the first inlet; a second inlet for indoor air from an interior space of the vehicle; and a second fan in communication with the second inlet to control (only) an air inflow through the second inlet. The first fan and the second fan are independently controllable to provide a desired mix of air to the vehicle HVAC component.
