Definitions

  • This invention refers to a filtration system for rail air-conditioning facilities, intended to achieve optimum ventilation of the passenger compartment of the train in combination with a set of air-conditioning facilities.
  • the purpose of the invention is to reduce the space necessary for the assembly of the filtration means used and the air-conditioning facilities associated with them.
  • the relationship between the air-conditioning facilities and the filtration means is carried out at a distance, that is to say, via ducts and means representing a very notable volume occupation, independently from whether the filtration system includes a single inlet for clean from outside, which on occasions is far from ideal as the wind direction, together with the travel direction of the train, may coincide or not, and in those cases in which the train travels in the opposite direction to the wind direction, it is inevitable sand will get in, even obstructing the inlet and the actual filtration means used.
  • the filtration system proposed was conceived to solve the problem stated above, based on a new idea for the implementation of the actual filtration system in combination with the air-conditioning facilities.
  • the filtration system is based on the fact that the filtration means are connected directly to the air-conditioning facilities, therefore minimising the distance between the aforementioned filtration means and the actual air-conditioning facilities, which reduces pressure head losses and makes it possible to use the smallest possible fan motors, for the set to occupy a space which is minimal.
  • the filtration means used are made up by a common duct for two inlets located in opposite directions, allowing for clean external air to be sucked in by one inlet or the other, depending on the direction the train is travelling in and the actual direction of the prevailing wind.
  • Each of the filtration means includes a nozzle with a filtration grille, a trapezoidal nozzle and with both inlets being positioned opposite to each other, for their less wide ends to concur at the common duct with a constant cross-section.
  • the common duct for both inlets lead to a common chamber, in which cyclonic filters are provided, where the sand that may have entered with the clean air will be withheld, with this sand then being extracted by means of an extractor motor established in accordance with that cyclonic filter chamber.
  • Another new characteristic is that previously to the common chamber there may be a single door or a door for each of the sections corresponding to one or the other air suction inlet.
  • the space occupied by the filtration means and the other components is minimal, thus notably saving space in the corresponding roof in which the set of the filtration system and the air-conditioning facilities is to be implemented.
  • Another characteristic is that the sand extractor motor remains fully protected from the air while the train is in motion, due to the symmetrical layout of the expansions determined by the air inlets.
  • the filtration system for rail air-conditioning facilities executed in accordance with the purpose of the invention is envisaged to be associated with air-conditioning facilities (1) and achieving air conditioning of the train, presenting as its first peculiarity the fact that such air-conditioning facilities are connected directly to the filtration means of the system with these being made up by a duct (2) which at its ends is finished off by two symmetrical expansions (3) in a trapezoidal shape, in such a way that each of them is provided with a nozzle (4) for air input, with a grille (5) to filter this air, in such a manner that the air accesses the common duct (2) thorough the expansions (3), and, via the corresponding doors (6), one for each section of the duct (2), it can reach the entrance (7) to a common chamber (8) provided with cyclonic filters to withhold the sand that may have entered with the clean external air as this was sucked by the actual filtration system.
  • the doors (2) may be in the form of a single door located at the entrance (7) of the common chamber (8).
  • the filtration system also includes filter mesh (10).
  • Both the duct (2) with its expansions (3) and the common chamber (8) of the cyclonic filters and the area for the location of the filter mesh (10), are supplemented with their corresponding opening covers (11), the same as the area of the air-conditioning facilities (1), in order to allow for these covers to be opened (11) to perform the maintenance and cleaning of all the components.
