Embodiments of the disclosure can relate to a ceiling mounted air distribution system for a railcar. According to one embodiment of the disclosure, a ceiling-mounted air distribution plenum may include: a diffuser configured to transmit air to at least one first air channel, the at least one first air channel having a first end configured to couple to the diffuser, a second end distal from the first end; at least one second air channel disposed proximate to and longitudinally with the at least one first air channel, the at least one second air channel having a first end configured to couple to the diffuser, a second end distal from the first end, and at least one air distribution hole, and at least one channel divider disposed to separate the at least one first air channel and the at least one second air channel.

The germ protection system for vehicles, hospitals, restaurants, schools, nursing homes, lifts and the like uses: a) A system that prevents germs: bacteria, protozoa, viruses or parasites from being breathed in vehicles or closed premises, lifts or the like, blowing or sucking air, b) An independent air installation that applies air conditioning, fed with turbofan engines, to the individual air blowing nozzles in the ceiling or backrest of the compartments of each passenger, c) An independent air installation using compressors that extracts and compresses the outside air, and apply it to the individual air blowing nozzles in the ceiling or backrest of the compartments of each passenger, d) A system that uses an individual installation to replace oxygen system in case of emergency, e) A system that is valid simultaneously for protection against germs and for breathing in case of emergency. The air is filtered, disinfected, its pressure, temperature and humidity regulated, and through some ducts it is applied to the masks, helmets, hoods, their ducts or nasal cannulas. f), A system that is coupled to the individual air supply nozzle of the passengers, using for this purpose at the end of the duct of the mask, face mask screen, diving suit or helmet.

An air purification system for use with rail car HVAC system to remove or destroy harmful pathogens in the air. The air purification system has a housing with an inlet, an outlet, and a passageway extending between the inlet and the outlet. An intense field generator and filter is used to charge any particles in the air and remove them from the air flow. An ultraviolet radiation source is positioned to direct ultraviolet illumination into the passageway. Finally, a dielectric barrier discharge unit having a high voltage electrode coupled to a dielectric barrier and a ground electrode spaced apart from the high voltage electrode is used to form a low temperature plasma chamber is in communication with the passageway so that the ions created in the plasma chamber will attach to and destroy any remaining particles in the air flow.

An on-vehicle air conditioner includes a suction port disposed on a ceiling of a vehicle cabin to suction air within the vehicle cabin, a door discharge port disposed at an upper end of a door opening portion located on a wall face of the vehicle to discharge air downward, and an upper duct configured to guide to the door discharge port the air suctioned by the suction port.

A recreational vehicle air conditioner includes an indoor cover defining an indoor air plenum, an outdoor air plenum, and a shaft aperture. An indoor fan is positioned within the indoor air plenum, a drive motor is positioned in the outdoor air plenum, and the indoor fan and the drive motor are coupled by a drive shaft that passes through the shaft aperture. A debris shield, such as an annular rubber washer, is positioned around the drive shaft within the outdoor air plenum for blocking debris from passing through the shaft aperture.

A vehicle air-conditioning apparatus includes a refrigerant circuit including a heat exchanger, a fan which sends air to the heat exchanger, and a controller which controls the refrigerant circuit and the fan. The vehicle air-conditioning apparatus is mounted on a vehicle. The controller determines if a position of the vehicle or a speed of the vehicle satisfies a predetermined condition. The controller acquires a physical quantity, the physical quantity having already been correlated with a clogging amount of the heat exchanger and the correlation being dependent on whether the predetermined condition is satisfied. The controller determines whether or not clogging occurs in the heat exchanger based on the physical quantity.

A seat air conditioning system includes a seat air conditioner provided for each seat of a vehicle, and a portable terminal configured to control the seat air conditioner. The seat air conditioner controls rotation of a fan with intensity in response to a start signal when starting communication with the portable terminal. The seat air conditioner starts a connection setting process when receiving a response signal in response to the start signal. The portable terminal determines a digital signal by binarizing an intensity of sound detected by a microphone. When the digital signal is the start signal, the portable terminal transmits a response signal to start the connection setting process.

An air handling system for distributing airflow in a vehicle is disclosed and includes a passenger compartment configured to contain one or more occupants, a cargo compartment, and a flow regulating valve configured to actuate into a commanded position to apportion airflow between the passenger and cargo compartments. The air handling system also includes one or more processors in electronic communication with the flow regulating valve and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the air handling system to receive one or more signals indicating a total available airflow rate available to the vehicle and a system configuration. The one or more processors instruct the flow regulating valve to actuate into a commanded position. The commanded position is calculated based on at least a target cargo airflow rate.

A reversible refrigeration cycle system is configured to provide heating and cooling to condition passenger air for a vehicle such as, for example, a bus. The reversible refrigeration cycle system includes a storage tank for storing fluid, a compressor, a plurality of coils, and valves for selectively conducting the fluid to the plurality of coils.
