Definitions
- the invention relates to a rail vehicle, comprising at least one vehicle interior, an air conditioning and air supply system for the vehicle interior with an intake for supplying outside air into the vehicle interior, and at least one unit.
- aggregates In addition to the vehicle interior, aggregates also require air cooling under certain climatic conditions in order to maintain their function or to protect their components. Since natural convection for cooling is usually sufficient, is not sufficient, outside air is used for cooling. In this case, too, fans and special filter systems are required. Here, too, the entry of sand must be avoided. The outside air that is sucked in is passed through particle separators and/or filters, grilles, in order to reduce the particle load to a tolerable level. Alternatively, the units or parts such as heat exchangers, pumps/compressors in these systems are designed to be particularly robust in order to withstand particularly aggressive environmental influences.
- the air flow through the heat exchanger may be briefly reversed to blow away any particles that have settled. This does not help against abrasion caused by sand, for example, and is not helpful.
- the invention is based on the object of providing a rail vehicle that is structurally simpler and reduces maintenance costs. This object is achieved by the features of claim 1. Advantageous embodiments and further developments are the subject of the subclaims.
- a rail vehicle comprising at least one vehicle interior, an air conditioning and air supply system for the vehicle interior with an intake for supplying outside air into the vehicle interior, and at least one unit.
- the rail vehicle is designed to supply the unit with air from the vehicle interior.
- the air from the vehicle interior is used.
- This air has already been cleaned when it is sucked in by the rail vehicle's air conditioning and air supply system and, after its primary use in the vehicle interior (e.g. passenger compartment), is only slightly contaminated with particles (compared to, for example, the outside air in deserts, which is heavily contaminated with sand particles). If this air from the vehicle interior is specifically passed through units such as cooling systems for transformers, traction motors or Gailey cooling units, the pollution from the ambient air sucked in from outside (outside air) is reduced or eliminated.
- the energy efficiency of the rail vehicle can also be increased because when the ambient temperature is high, the exhaust air from the air conditioning and air supply system, i.e. the air from the vehicle interior, is cooler than the outside air. Heat exchange processes for cooling are therefore more efficient when the exhaust air from the air conditioning and air supply system is used.
- the humidity of the outside air is particularly low in deserts.
- the exhaust air (exhaust air) from the air conditioning and air supply system is usually loaded with a higher relative humidity, for example from the passengers in the rail vehicle. If used correctly, this further increases the efficiency of the thermodynamic cooling process. Through the targeted use of exhaust air from the air conditioning and air supply system, the effort and costs for upgrading rail vehicles in particularly aggressive environments such as deserts are minimized. In addition, the energy efficiency of the rail vehicle increases.
- the vehicle interior may preferably be a passenger compartment.
- the at least one unit is or comprises a unit arranged outside the vehicle interior.
- the at least one unit 200 is or comprises a unit 200 arranged within the vehicle interior 10.
- the rail vehicle has an air supply device which is designed in such a way that it supplies the unit with air from the interior.
- a corresponding intake system is provided in the vehicle interior near the unit.
- the air supply device has an exhaust air unit which sucks in air from the vehicle interior and supplies it to the unit.
- the air conditioning and air supply system has at least one air conditioning device for conditioning the outside air to be supplied to the vehicle interior.
- the conditioning of the air can, for example, include adjusting the air temperature and the air humidity.
- the air conditioning device conditions the air with regard to use in the vehicle interior. Furthermore, when conditioning the outside air, it can be taken into account that after flowing through the vehicle interior, it is supplied to at least one unit.
- the air conditioning and air supply system has at least one sand and dust filter system for filtering the outside air taken in. This filters out the sand and dust from the outside air before it is fed into the rail vehicle.
- the already pre-cleaned exhaust air from the air conditioning and air supply system can also be fed to a compressed air generation device in the rail vehicle in order to minimize the processing of the intake air.
- the compressed air generation device is designed to supply a compressed air system of the rail vehicle with compressed air.
- compressed air brakes or other pneumatic systems are connected to the compressed air system.
- the air conditioning and air supply system is arranged above the vehicle interior.
- the air conditioning and air supply system is preferably arranged in the roof area of the rail vehicle.
- the air conditioning and air supply system is therefore preferably arranged on the car body.
- the unit is arranged underneath the vehicle interior, preferably in the underfloor area. This ensures that the unit is arranged in a location that offers the rail vehicle a low ossible center of gravity.
- the air conditioning and air supply system is located in the roof area, air flow through the vehicle interior from top to bottom can be achieved.
- an additional sand or dust filter can be arranged between the vehicle interior and the unit.
- This additional sand or dust filter can be designed, for example, as a fine filter or as a filter mat. This provides a less costly and/or maintenance-intensive means of supplying further filtered air to the unit.
- the at least one unit is assigned an outside air supply device arranged in the region of the unit, via which outside air from the environment of the unit can be supplied to the at least one unit for cooling, preferably in addition to the air in the vehicle interior.
- the required air volume flow of the unit is temporarily or permanently (e.g. in the case of traction engine cooling) greater than the volume flow emitted from the vehicle interior (exhaust air from the air conditioning and air supply system), this can be used proportionately as intake air and thus reduces at least the particle input and thus the load on the unit.

- the air conditioning and air supply system 100 has at least one air conditioning device 120 for conditioning the outside air to be supplied to the vehicle interior 10.
- the air conditioning device 120 is designed to condition the outside air in terms of temperature and/or humidity before it is supplied to the vehicle interior 10.
- the air conditioning and air supply system 100 has at least one sand and dust filter system 130 for filtering the outside air taken in.
- the air conditioning and air supply system 100 can have an outlet 140 which is designed to discharge a portion of the air sucked in through the intake 110 after passing through The air conditioning and air supply system 100 flows back to the
- the air conditioning and air supply system 100 is arranged above the vehicle interior 10.
