Tri-generation turbomachine device and vehicle comprising such a device

A turbomachine device for a motor vehicle, the device comprising:

• a first turbocompressor comprising a first compressor and a first turbine;
• a second turbocompressor comprising a second compressor and a second turbine;
• a stream intercooler connected to the first compressor and to the second compressor;
• a first heat exchanger connected to an exhaust outlet, and to the second compressor, itself being connected to the two turbines;
• the device being configured to send a fluid stream from the first compressor, to the intercooler, to the second compressor, to the first heat exchanger, and to the turbines, wherein the device comprises at least one vehicle interior air conditioning section;
• wherein the interior air conditioning section comprises an interior air conditioning circuit passing through the intercooler and associated with a circulation pump for a second fluid stream, the air conditioning circuit including an interior air heating exchanger;
• and
• wherein the interior air conditioning section comprises a stream bypass between the second compressor and the first heat exchanger, a bypass heat exchanger, coupled to the air conditioning circuit and to the stream derived from the bypass, an air conditioning turbine connected downstream of the bypass heat exchanger, and at least one first cooling exchanger for producing interior cold connected downstream of the air conditioning turbine.
