Definitions
- the invention relates to a retrofittable air curtain for a rail vehicle.
- the invention further relates to a method for operating a retrofittable air curtain.
- the invention relates to a rail vehicle.
- Rail vehicles are exposed to very different temperatures during operation. As a result of the large window panes, the interior or There is a greenhouse effect in the passenger area of a rail vehicle, which without countermeasures would lead to extremely high temperatures in the interior of the rail vehicle, especially in strong sunlight and high outside temperatures.
- air conditioning systems that cool down the air in the interior when outside temperatures are high and heat it up when outside temperatures are low are usually used.
- the task is therefore to reduce the energy consumption for air conditioning in the interior of rail vehicles and also in existing rail vehicles compared to the energy consumption of conventional air conditioning systems in rail vehicles.
- the retrofittable air curtain according to the invention has an electric blower unit for sucking in air that is separate from an air conditioning system of a rail vehicle.
- An air curtain also known as a door air curtain, door air curtain or air barrier system, is intended to be understood as a device that uses powerful fans to separate differently conditioned air masses from each other on frequently opened doors using a barrier of flowing air and thus prevents or at least significantly reduces their exchange.
- This barrier includes a directed air flow that circulates between the exhaust opening and intake opening of the air curtain. Air is preferably sucked in from the interior of the rail vehicle, since the air is then preconditioned. D. H .
- the air is already cooled by the air conditioning and has a relatively low CCh content, as the air conditioning ensures sufficient air circulation between the external environment and the interior.
- Under a blower unit there should be a unit for sucking in air, preferably from the surroundings of the blower unit or from the surroundings of an inlet of the blower unit and for the further transport of the sucked in air.
- Part of the retrofittable air curtain is also a fan outlet set up in the side area of an entrance and exit area in the vicinity of a passenger door of the rail vehicle with an air control unit for determining the air flow direction of the air flowing out of the fan outlet.
- the air guide unit includes air guide elements which, through their spatial arrangement, limit the air flow to a desired direction. set .
- the side area should be understood as the area to the right and left of a recess formed by an opening in the passenger door. Figuratively speaking, this is the area in which the side part of the door frame is arranged and the side area of the associated entrance and exit area of the rail vehicle runs.
- This side area is usually provided with panels and forms the side part of the door frame, but usually extends further into the interior of the rail vehicle.
- the panels that are already conventionally present in the input and output areas can advantageously be used to accommodate the blower output, in particular one or more air outlets that are included in the blower output.
- the fan outlet preferably includes air outlets on both sides of the inlet and outlet area, so that the partial flows of air flowing laterally out of the air outlets combine to form a total flow, which, now that the two transverse components of the two partial flows ideally cancel each other out, is perpendicular to the door opening d. H . flows exactly in the opposite direction of an inhibiting air flow.
- the air flow direction of the partial flows is preferably horizontal and diagonal due to the lateral arrangement of the fan outlet oriented towards the door and the direction of entry and exit.
- the resulting total air flow is parallel to the entry and exit direction or directed vertically towards the door opening.
- the retrofittable air curtain includes a transmission line between the blower output and the electric blower unit.
- the air curtain according to the invention can be installed independently of an air conditioning system on a rail vehicle.
- the air curtain is installed completely independently of the technical components of the air conditioning system. Due to this independence of the air curtain, the capacity of the fan or of the air conditioning fan is not reduced or impaired.
- D. H . the full capacity of the air conditioning system is still available for cooling the interior of the rail vehicle.
- the air flow direction of the air flowing out of the fan outlet can be adjusted and determined by the air guide unit, it can be achieved that an air flow that occurs when the passenger door is open is between the external environment of the rail vehicle and the interior or. the passenger compartment of the rail vehicle is counteracted, thereby achieving a thermal insulation effect for the interior.
- the thermal insulation makes it possible to avoid a sharp increase in the power consumption of the rail vehicle's air conditioning system when the passenger door is opened. In particular, higher switching states of the air conditioning system are only achieved at higher outside temperatures than without the use of the retrofittable air curtain.
- the energy consumption of the rail vehicle's air conditioning system is therefore reduced and wear-prone performance peaks during operation of the air conditioning system are avoided. Since the separate electric blower unit air from the interior, the CC ⁇ content in the interior is reduced because the air conditioning system supplies air with a lower C ⁇ 2 content from the external environment of the rail vehicle.
- an electric blower unit that is separate from an air conditioning system of the rail vehicle is started to suck in air from the interior. Furthermore, the air is transferred through a transmission line between the electric blower unit and a side area in the vicinity of a passenger door or in the side area of an entrance and exit area of the rail vehicle closed by the passenger door, which has an air guide unit for determining the air flow direction of the air flowing out of the blower outlet. Finally, the air is led out of the fan outlet in the specified air flow direction.

- Both air outlets preferably cover approximately half of the interior height of the rail vehicle.
- the air outlet near the floor or the air outlet near the ceiling is preferably activated or deactivated depending on a temperature difference between the external environment of the rail vehicle and the interior of the rail vehicle.
- the outside temperature is high, cooled inside air can be blown counter to the relatively heavy inside air flowing out in the floor area via the air outlet near the floor, and when the outside temperature is low, warm inside air can be blown against the relatively light warm inside air flowing out in the ceiling area via the air outlet near the ceiling.
- the air flow directions of the air outlet near the floor and the air outlet near the ceiling can also be adjusted depending on a temperature difference between the external environment of the rail vehicle and the interior of the rail vehicle.
