A method for cleaning an air duct, in particular an air duct of a rail vehicle. The need to cool at least one load connected to the air duct is determined, the need to clean the air duct is determined, and a cleaning process of the air duct is initiated if there is no or a low need to cool the at least one load connected to the air duct and if there is a need to clean the air duct. There is also described an air intake system.

An air conditioning apparatus for a railway vehicle includes a compressor to compress a refrigerant, a condenser to condense the compressed refrigerant, an expander to expand the condensed refrigerant, an evaporator to vaporize the expanded refrigerant, and refrigerant piping connecting the compressor, the condenser, the expander, and the evaporator. One of the condenser or the evaporator is an indoor heat exchanger, and the other is an outdoor heat exchanger. At least one of the outdoor heat exchanger or the indoor heat exchanger includes a body including planar heat-transfer members and fins alternately stacked in a thickness direction of the planar heat-transfer members so as to have a stacked structure. Each planar heat-transfer member includes at an interior thereof refrigerant flow paths for flow therethrough of the refrigerant. The refrigerant flow paths are arranged in a direction in which air passes through the fins.

The invention relates to a device for cooling a component for use in a vehicle. Said component comprises a first side face and a second side face opposite each other and cooling channels running between the first side face and the second side face. The cooling device comprises a first opening, a second opening and a set of baffles configured such that movement of the vehicle generates an airflow entering one of the first opening and the second opening and exiting the other, the set of baffles being configured to guide the airflow through the cooling channels of the component.

According to some embodiments, a refrigerated railcar comprises a pair of side walls, a roof, a floor, and a refrigeration unit. The floor comprises a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit. The floor further comprises at least two top plates coupled to the bottom structure (e.g., via a pivot rod). Each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls. Lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.

Disclosed are a system and method for enhancing antiviral capabilities of rail vehicles using an air filter. The air filter has a filter structure including an antiviral material, the antiviral material having particles comprising silver, and, in particular, including a composition containing silver, and the antiviral material also including liposomes. Further disclosed are methods for operating air treatment systems of a rail vehicle so as enhance antiviral capabilities.

A method for operating an air conditioning system for a vehicle for transporting persons. The air conditioning system, depending on the current number of passengers in a passenger compartment of the vehicle (level of occupation), controls a fresh air volume flow to be introduced into the passenger compartment from outside the vehicle in order to maintain a predefined minimum ambient air quality. The air conditioning system determines a total water mass flow, which is currently produced by the passengers in the passenger compartment, on the basis of air-conditioning measurement values and a current value for at least one operating parameter of the air conditioning system. From the total water mass flow and a predefined value for a water mass flow produced by a single passenger, the system determines the current number of passengers in the passenger compartment. There is also described an air conditioning arrangement for carrying out the method.

According to some embodiments, a refrigerated railcar comprises a pair of side walls, a roof, a floor, and a refrigeration unit. The floor comprises a bottom structure comprising a plurality of channels for return air flow from an interior of the railcar to the refrigeration unit. The floor further comprises at least two top plates coupled to the bottom structure (e.g., via a pivot rod). Each of the top plates extends longitudinally along the bottom structure and is configured to rotate up and away from the bottom structure proximate one of the side walls of the pair of side walls. Lifting an edge of a top plate opposite the edge of the top plate pivotally coupled to the bottom structure causes the top plate to rotate to an upright position exposing the plurality of channels of the bottom structure.

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.

An embodiment of the present disclosure provides an interior decoration structure and a railway vehicle with the interior decoration structure. The interior decoration structure is located inside a vehicle body. The interior decoration structure includes: a plurality of interior decoration components, the plurality of interior decoration components being spliced inside the vehicle body in sequence, wherein at least one pair of two adjacent interior decoration components are connected by an inserted-connected structure. The interior decoration structure in the present disclosure solves the problem in the related art that interior decoration parts are prone to unstable connection due to a mounting mode of an interior decoration structure.
