Claim 0:
1. A vehicle thermal management system, comprising:
a heating, ventilation, and air conditioning (HVAC) subsystem including a first compressor and a first refrigeration cycle including a first refrigerant loop fluidly connected to the first compressor and a branch conduit branching off from the first refrigerant loop;
a battery cooling subsystem including a battery coolant loop fluidly connected to a battery pack;
a powertrain cooling subsystem including a powertrain coolant loop fluidly connected to a powertrain component;
a second refrigeration cycle including a second compressor, a condenser located on a downstream side of the second compressor, and a second refrigerant loop fluidly connected to the condenser;
a refrigerant chiller mounted between a first refrigerant circulating in the branch conduit and a second refrigerant circulating in the second refrigerant loop and configured to transfer heat between the first refrigeration cycle and the second refrigeration cycle; and
a battery chiller mounted between the second refrigeration cycle and the battery coolant loop and configured to transfer heat between the second refrigeration cycle and the battery coolant loop,
wherein the condenser of the second refrigeration cycle is thermally connected to at least one of the battery coolant loop and the powertrain coolant loop.
