Definitions

• the present invention relates to a filtration system for railway air conditioning equipment, intended to achieve optimum ventilation of the passenger room of the train in combination with air conditioning equipment.
• the object of the invention is to reduce the space necessary for the assembly of the filtration means used and the air conditioning equipment associated with them.
• the filtration system that has been recommended has been designed to solve the problem described above, based on a new conception of the implantation of the filtration system itself in combination with the air conditioning equipment.
• the filtration system is based on the fact that the filtration means used are directly coupled to the air conditioning equipment, thereby minimizing the distance between said filtration means and the air conditioning equipment itself, which reduces load losses and makes possible the use of fan motors as small as possible, occupying the whole a minimum space.
• the filtration means used are constituted by a common conduit to two entrances provided in opposition, allowing the aspiration of clean outside air by one or the other inlet, depending on the direction of train movement and the direction of the prevailing wind .
• means are provided that allow automatic selection of the opening of the input that is desired so that the outside clean air is sucked through it, depending on the direction of the prevailing wind and the direction of the train itself,
• the performance will always be optimal and the most advantageous, and it can also establish that the two entrances are closed in infringing areas of sand and the entrance is opened corresponding in the cleanest areas.
• Each of the filtration means includes a nozzle with a filtration grid, a nozzle that is of a trapezoidal configuration and both are made in opposition, that is to say contrary so that its smaller sections concur in the common duct and of constant section ,
• Another characteristic of novelty is that prior to the common chamber there may be a single gate or a gate for each of the sections corresponding to one or another air intake.
• the occupancy of the filtration media and other components is minimal in terms of space occupied by them, thereby achieving significant space savings in the corresponding ceiling in which the whole filtration system and equipment will be implanted. corresponding air conditioning.
• Another feature is that due to the symmetrical arrangement of the expansions that detract from the air inlets, the sand extractor motor is fully protected against air during the train's run.
• Figure 1 shows a representation corresponding to a higher perspective of the filtration system object of the invention, without the corresponding covers, to show all the components and location for them.
• Figure 2. Shows the same assembly represented in the previous figure, but with the covers closing all the compartments corresponding to the filtration means and leaving the location of the air conditioner free and uncovered.
• the filtration system for railway air conditioning equipment carried out in accordance with the object of the invention is intended to be associated with an air conditioning equipment (1) and achieve air conditioning of the train, presenting as
• the first feature is the fact that said air conditioning equipment (1) is directly coupled to the system's filtration means, which are constituted from a duct (2) that ends at symmetrical expansions (3) between yes and of trapecial configuration, so that in each of them a nozzle (4) is provided for the air inlet, with a grid (5) for filtering that air, so that through the expansions (3 ) the air accesses the common duct (2) and through corresponding gates (6), one for each section of duct (2) can reach the entrance (7) to a common chamber (8) in which some filters are provided The cyclonic retention of the sand that could have entered with the clean outside air when it was sucked by the filtration system itself.
• the gates (2) can be materialized by a single gate located at the entrance (7) of the common chamber (8).
• the sands that reach the common chamber (8) are aspirated by a Extractor motor (9) that is perfectly protected against the wind and centers the sands on which the ends of the common duct (2) are finished.
• the filtration system also includes filter blankets (10).
• Both the duct (2) with its expansions (3) and the common chamber (8) of the cyclone filters and the location area of the filter blankets (10), are complemented by corresponding practicable covers (1 1), as well as that the area of the air conditioning equipment (1), in order to allow the opening of these covers (11) and carry out the maintenance and cleaning of all components.
• the nozzles (4) established in the opposite air inlets to the filtration system have an inclination that is established in the own grids (5) of said inlet nozzles (4), which establishes a protection of those grilles (5) which causes the air to fall, either by its own weight before entering the grid, or aerodynamically jumping over them.
• the filtered air at txa 7 is from the common chamber (8) with the cyclonic filters, passes to the filtration blankets (10), which are special and in which the rest of the sand is collected, to allow air to pass through them only clean for air conditioning equipment (i).
