MULTI-MODE THERMAL CONTROL SYSTEM FOR A VEHICLE

A thermal control system for a vehicle has a battery thermal control loop having a refrigerant-fluid heat exchanger, a powertrain thermal control loop, a refrigerant loop having a compressor, a condenser, an evaporator, a first valve coupling the evaporator to the refrigerant loop and a second valve coupling the refrigerant-fluid heat exchanger to the refrigerant loop, and a first valve assembly. When the first valve assembly is in a first mode, the battery thermal control loop and the powertrain thermal control loop are not in fluidic connection. When the first valve assembly is in a second mode, the battery thermal control loop and the powertrain thermal control loop are coupled together in partial bleed-off. A cabin thermal control loop with a liquid-air heat exchanger provides temperature control of a cabin of the vehicle. First, second, third, fourth, fifth and sixth connecting branches connect the battery, powertrain and cabin thermal control loops.
