Thermal management device of a motor vehicle with constant pressure valve

摘要

The present invention relates to a thermal management device (1) of a motor vehicle, said thermal management device (1) comprising a refrigerant circuit in which a refrigerant fluid is intended to circulate, said refrigerant circuit comprising a loop main (A) comprising in the direction of circulation of the refrigerant fluid a compressor (3), a first heat exchanger (5), a first expansion device (7) and a second heat exchanger (9), said fluid circuit refrigerant further comprising a first bypass branch (B) configured to bypass the second heat exchanger (9), the first bypass branch (B) comprising a third heat exchanger (13), the first bypass branch (B) comprising a first constant pressure valve (15) disposed downstream of the third heat exchanger (13).
