At least two roof segments are configured in such a way that the protruding region of the outer wall or inner wall of one roof segment is interlockingly, force-lockingly and/or integrally connected to the non-protruding region of the outer wall or inner wall of the neighbouring roof segment. The roof segments consist at least partially of a fibre-reinforced plastic composite.

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.

An air-conditioning system for a vehicle suitable for flammable refrigerants of categories A2, A2L, and A3 is provided. The system is a compact piece of equipment for installation on a vehicle roof and has equipment sections for air treatment and a compressor-liquefier unit, and optionally an outgoing air, an electrical switchbox, and/or silencer. The system is a direct evaporating system in which the air to be conditioned for a passenger area is sealed off within the air-conditioning system such that, in the event of leaks at refrigerant-conducting assemblies, ingress of flammable refrigerant into the interior of the vehicle is prevented. The refrigerant-conducting assemblies and components are located outside the areas where comfort air is conducted, in a separate housing and open to the surroundings.

An air-conditioning control system includes a first inverter that drives a first driving target in accordance with commands received via a first communication network, a second inverter that drives a second driving target in accordance with commands received via the first communication network, a first controller that is capable of controlling the first inverter and the second inverter by transmitting commands via the first communication network, and a second controller that is capable of controlling the first inverter and the second inverter by transmitting commands via the first communication network. Each of the first controller and the second controller is capable of transmitting, to the first inverter and the second inverter via the first communication network, an invalidation command for invalidating the commands therefrom.

Provided is a pressure regulating method in a vehicle, comprising the following steps: S1, detecting a pressure value P in a vehicle compartment; and S2, regulating and correcting the angle of a waste exhaust valve by a control apparatus according to a starting command until target requirements are met. A pressure regulating apparatus in a vehicle for realizing the pressure regulating method is further comprised. The pressure in a vehicle compartment is regulated by regulating the angle of an exhaust valve, so that the pressure in the vehicle compartment is always controlled within a reasonable range, and the problem of pressure change in a vehicle during the operation of the vehicle is solved; meanwhile, comfort of sitting in the vehicle is achieved, and the cost of testing is lowered.

An air purification system for a passenger cabin of a transport vessel. The air purification system comprises an elongated air compartment having a panel, with a plurality of openings along the panel. Air filters reside within the various openings to receive air from inside the cabin. The system also includes a plurality of air tubes. Air moves through the air tubes, aided by a source of compressed air to motive flow valves. The motive flow valves create suction to draw air into the air compartment from the passenger cabin. The system also includes at least one UV-C light source. The UV-C light resides within the air compartment, and disinfects the air moving through the air compartment. A plurality of air outlets are also placed along the lower panel, with each outlet configured to release air at selected points to provide a continuous distribution of filtered and disinfected air into the passenger cabin.

A refrigerant quantity diagnosis device includes: an evaluation value calculation part that calculates a refrigerant quantity index evaluation value including a ratio of a measured refrigerant quantity index value to a reference refrigerant quantity index value in each of a normal period and a determination period; and a refrigerant quantity diagnosis part that diagnoses a refrigerant quantity based on the refrigerant quantity index evaluation value. The evaluation value calculation part calculates a first refrigerant quantity index evaluation value in the normal period and a second refrigerant quantity index evaluation value in the determination period, based on respective reference refrigerant quantity index values having respective values associated with an operating condition of interest, and respective measured refrigerant quantity index values. The refrigerant quantity diagnosis part compares information on the first refrigerant quantity index evaluation value with that on the second one and thereby diagnoses the refrigerant quantity.

An air-conditioning control system includes a first inverter that drives a first driving target in accordance with commands received via a first communication network, a second inverter that drives a second driving target in accordance with commands received via the first communication network, a first controller that is capable of controlling the first inverter and the second inverter by transmitting commands via the first communication network, and a second controller that is capable of controlling the first inverter and the second inverter by transmitting commands via the first communication network.
