Definitions

  • the invention relates to a pressure protection system for high-speed trains. It is a combined valve closing - bypass passage - System, as well as a procedure for its operation.
  • This system has the disadvantage that, in the event of pressure protection, the air quality deteriorates due to the lack of fresh air supply and the CO 2 level in the wagon can exceed the limit values required by the travelers' metabolic process.
  • the advantage of this system is the complete prevention of inadmissible pressure waves from entering the car interior.
  • Previous solutions therefore use, in addition to the fresh and continuous fans, additional pressure protection fans that have a very steep characteristic and whose discharge pressure difference is higher than the pressure surge to be expected. These fans are switched on on sections of the route on which pressure surges are to be expected, regardless of whether a Pressure protection event is present or not.
  • the object of the invention is a method to develop, which the disadvantages of the above. solutions avoids.
  • the pressure protection system then consists of a quick-closing valve with an adjustable opening cross-section. In the event of pressure protection, part of the fresh air inlet and outlet air openings are closed on the one hand, and on the other hand a smaller amount of air is conveyed via a bypass to ensure air quality.
  • the air conditioner 2 is arranged in the carriage 1.
  • the supply fan of the device sucks air on the one hand through the weather protection grille 14, the opened pressure protection valve 12 and the fresh air duct 3, and on the other hand recirculates air through the recirculated air duct 4 and conveys the supply air via the supply air duct 5 into the compartments of the car.
  • the correct ratio of circulating air and fresh air is ensured by the circulating fan 7 or by circulating air flap positions or by both measures.
  • the exhaust air enters the environment via the exhaust air duct 6, the exhaust fan 9, the opened pressure protection valve 13 and the weather protection grille 14.
  • Bypass fans 10 and 11 are arranged parallel to pressure protection valves for fresh air 12 and for exhaust air 13.
  • the bypass fans 10 and 11 are switched on by the pressure evaluation and control unit 15 as soon as there is a risk that the permissible pressure change conditions inside the car will be exceeded and the pressure protection valves 12 and 13 will therefore be closed.
  • the air is conveyed via the weather protection grille 14 and the fresh air pressure protection valve 12 and the carriage 1.
  • the amount of air that is added as fresh air from the outside is returned to the environment by the exhaust fan 9 via the exhaust air pressure protection valve 13 and the weather protection grille 14.
  • the pressure protection valve for outside air 12 is closed to such an extent that the amount of air flowing in due to the pressure difference between the pressures before and after the valve almost corresponds to the flow rate of the bypass fan exhaust air 11 started at the same time, so that no pressure increase inside the carriage 1 entry.
  • the pressure relief valve for exhaust air 13 is closed to such an extent that the amount of air flowing out due to the pressure difference between the pressures upstream and downstream of the valve almost corresponds to the delivery rate of the bypass fan fresh air 10 started at the same side point, so that no pressure drop inside the carriage 1 entry.
