Abstract
A reversible thermal management device for a motor vehicle includes a refrigerant fluid circuit containing a main loop which has, successively, a compressor, an internal condenser, a first expansion device and an external evaporator/condenser. The device also has a three bypass branches. The third bypass branch has a heat exchanger. The device further includes a device for redirecting the refrigerant fluid coming from the internal condenser towards the first expansion device or the first bypass branch, a stop valve for the refrigerant fluid, arranged on the main loop, a first check valve arranged on the second bypass branch to block the refrigerant fluid coming from the internal condenser, a second check valve arranged on the main loop to block the refrigerant fluid coming from the evaporator/condenser, and a device for redirecting fluid coming from the first expansion device towards the heat exchanger of the third bypass branch or the evaporator/condenser.
