SYSTEM FOR THE GENERATION OF COMPRESSED AIR AND FOR AIR CONDITIONING, FOR A RAILWAY VEHICLE

A system is described comprising a first compressor for generating compressed air to feed a main tank and a main brake pipe of the railway vehicle through an air drying unit and a second compressor for compressing a refrigerant gas for an air conditioning system. The system comprises a single electric motor for generating a mechanical torque to be selectively supplied to the first compressor, or to the second compressor, or simultaneously to the first and second compressors, as a function of a) a first electrical signal generated by a pressure measurement device and indicative of a pressure present in the main brake pipe, or in the main tank, and b) at least a second electrical signal coming from the air conditioning system and indicative of a temperature or pressure or humidity value, and at least a third electrical signal indicative of a temperature of an environment.
