Abstract

The invention relates to a turbomachine device of the intercooled recuperated reheated gas turbine (IRReGT) type. The invention relates to applications for motor vehicles. The turbomachine device comprises a first turbocompressor (C 1 , T 2 ), a second turbocompressor (C 2 , T 1 ), two combustion chambers (CC 1 , CC 2 ) or an exhaust line (EL), an intercooler (IC) and a heat exchanger (E 1 ). The device is configured to implement a stream of fluid (F 1 ) from the first compressor (C 1 ) to the intercooler (IC), to the second compressor (C 2 ), to the heat exchanger (E 1 ), to the turbines (T 1 , T 2 ). According to one aspect, the device comprises at least one vehicle interior air conditioning section comprising at least a means for producing cold (E 1 F, E 2 F) and/or heat (E 1 C) on the basis of said stream (F 1 ).

Claims (15)

1 . 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.

2 . The turbomachine device according to claim 1 , wherein the interior air conditioning section comprises said stream bypass between the second compressor and the first heat exchanger, an air conditioning turbine and said at least one means for cooling, said at least one first cooling exchanger comprising a first interior air cooling exchanger and a second interior air cooling exchanger; said air conditioning turbine being connected downstream of the first interior air cooling exchanger; said second interior air cooling exchanger producing interior cold connected downstream of the air conditioning turbine.

3 . The turbomachine device according to claim 2 , wherein the air conditioning turbine is a turbocompressor turbine associated with an air conditioning compressor connected downstream either between the first compressor and the intercooler, or upstream of the first compressor.

4 . The turbomachine device according to claim 1 , wherein the air conditioning turbine is a turbocompressor turbine associated with an air conditioning compressor connected downstream either between the first compressor and the intercooler, or upstream of the first compressor.

5 . The turbomachine device according to claim 1 , comprising an combustion chamber between the second and first turbines.

6 . The turbomachine device according to claim 1 , wherein the turbocompressors are mounted on separate axes.

7 . The turbomachine device according to claim 6 , including an electric generator on each of said axes.

8 . A motor vehicle comprising a turbomachine device according claim 1 .
