Beschreibung
Zusammenfassung:	The present invention relates to a motor vehicle thermal management circuit (1) comprising a refrigerant loop (A) through which a refrigerant circulates, the said refrigerant loop (A) comprising: · a first compressor (3), · a first heat exchanger (5), · a second compressor (7), · a second heat exchanger (9), · a first expansion device (21), · a third heat exchanger (11), the said refrigerant loop (A) further comprising a bypass leg (B) connecting the refrigerant outlet of the second heat exchanger (9) to the refrigerant inlet of the first heat exchanger (5), the said bypass leg (B) comprising a second expansion device (22) controlled by the measurement of an intermediate temperature of the refrigerant leaving the first heat exchanger (5).
