A device for managing the electrical energy consumption of a set of passenger transport vehicles comprises: means for receiving a set of consumption information representative of the electrical energy consumed at a given time by the vehicles, means for determining an overall consumption, from the consumption information received, and means for generating a set of commands intended respectively for a subset of vehicles selected from among the vehicles of the set according to the service status thereof, the commands being generated to modify the operation of at least one air conditioning system of the vehicles so as to reduce the value of the determined overall consumption to a predefined value. The invention is applicable in passenger transport vehicles powered by an electrical network, such as rail transport vehicles, for example trains, subways, trams, trolleybuses, etc.

Provided is a railway vehicle air-conditioning duct that is capable of achieving a more uniform in-cabin temperature distribution through more appropriate volume distribution of conditioned air. A railway vehicle air-conditioning duct that supplies conditioned air generated by an air conditioner into a cabin and that extends in a vehicle length direction at a vehicle ceiling part has: a main duct; a chamber duct; a branch duct; and a guide part. The guide part is lower in height than the main duct, extends to a branch duct from the main duct or a partition wall in the main duct in a vehicle width direction, and supplies to the branch duct a portion of the conditioned air supplied to the main duct.

An air-conditioning apparatus for a vehicle includes a casing that an air inlet which communicates with an opening formed in a roof of a vehicle and through which air in the vehicle is formed in, and an apparatus main body that is installed in the casing and conditions the air, in the vehicle, which is sucked through the air inlet. A wiring through hole for passing a wiring cable extending from the apparatus main body through a space between the roof of the vehicle and the casing is formed in a bottom plate of the casing. The wiring cable is disposed so as to be passed through the space between the bottom plate and the roof of the vehicle via the wiring through hole from the apparatus main body and to extend into the opening from a position that is in the bottom plate and above the opening of the vehicle.

Each of the first outdoor heat exchanger and the second outdoor heat exchanger includes a body including a stacked structure in which refrigerant pipes and fins are alternately stacked in a direction perpendicular to a thickness direction in which airflow passes through the first outdoor heat exchanger or the second outdoor heat exchanger. Each refrigerant pipe internally defines a plurality of refrigerant flow paths arranged in the thickness direction. A first header pipe connects the refrigerant flow paths in each refrigerant pipe to one another at a first end of the body in a length direction of the refrigerant pipes. A second header pipe connects the refrigerant flow paths in each refrigerant pipe to one another at a second end of the body in the length direction of the refrigerant pipes.

An air-conditioning system in vehicle is installed in a vehicle in which a vehicle body center position and an aisle center position are different, and has an air conditioner. The air-conditioning system in vehicle has first and second outlets arranged on both sides of the vehicle in a vehicle width direction and discharging conditioned air having substantially the same air volume into an interior, and an air regulating member setting a merging position of air flows discharged from the first and second outlets to the position where the line segment connecting the vehicle body center position and the aisle center position is internally divided at a ratio of between 20:80 and 86:14.

An air conditioner includes: a suction port; a suction grill provided at the suction port and including a plurality of bars spaced apart from one another and arranged substantially parallel to one another and a suction surface located at suction-side end portions of the plurality of bars; and an air blower configured to suction air from the suction port through the suction grill. Each of the plurality of bars includes an inclined plate portion and a flow straightening plate portion, which are arranged in this order from the suction surface toward a downstream side of the flow of the air, the inclined plate portion being inclined with respect to the suction surface, the flow straightening plate portion being continuously formed from the inclined plate portion and extending in a direction substantially perpendicular to the suction surface and toward the downstream side.

The air conditioning device (10) includes a heat exchanger (12) intended to exchange heat with the air circulating in the air conditioning device (10), and an air distribution box (14), extending in a longitudinal direction (X) between a front part (14A) and a rear part (14B), and in a transverse direction between two side parts (14C). The distribution box is fastened to a ceiling (5) of the driving cabin (1), and comprises: in its front part (14A), a front inlet (16) for air coming from the cabin (1), connected upstream from the heat exchanger (12), and in each of its side parts (14C), a respective side outlet (18) for conditioned air, connected downstream from the heat exchanger (12).

Disclosed is a thermal control system for a tramcar. The system includes a roof profile (11) arranged above a compartment roof of the tramcar (10); a fuel cell system (12) and an air-conditioning system (14) arranged above the roof profile (11); and a heat dissipating system (13) arranged above the roof profile (11), where the fuel cell system (12) communicates with the heat dissipating system (13) via a piping (16), and the piping (16) is arranged with a circulating pump (15) for pumping a coolant to the heat dissipating system. The thermal control system solves the problem of low heat dissipating efficiency of a fuel cell in the prior art.

A vehicle air-conditioning system includes at least one chiller and one cold storage unit which is designed as a PCM storage system with phase change material. The refrigeration power required for air-conditioning and for charging the PCM storage system are provided by the chiller where the cold stored in the PCM storage system is supplied to the assemblies for air-conditioning the passenger compartment in selected operating states of the vehicle. A sufficiently large amount of cold can be conducted from a phase change material of the PCM storage system into the passenger compartment such that the chiller of the air conditioning system designed for cold generation is largely put out of operation and the discharge of larger amounts of heat from the rail vehicle into the tunnel is thereby avoided.
