Vehicular thermal management system

A vehicular thermal management system, the system comprising:

• a heating, ventilation, and air conditioning (HVAC) subsystem comprising:
• a compressor;
• a heating-side expansion valve disposed on a downstream side of the compressor;
• an exterior heat exchanger disposed on a downstream side of the heating-side expansion valve;
• a cooling-side expansion valve disposed on a downstream side of the exterior heat exchanger;
• an evaporator disposed on a downstream side of the cooling-side expansion valve;
• a distribution line configured to allow at least a portion of a refrigerant discharged from the exterior heat exchanger to be directed from an upstream side of the cooling-side expansion valve to the compressor;
• a battery comprising a refrigerant passage;
• a warm-up line configured to allow the refrigerant to be directed from the downstream side of the compressor to the battery;
• an interior condenser disposed between the compressor and the heating-side expansion valve;
• a first control valve configured to allow the refrigerant discharged from the compressor to be directed toward the interior condenser or the battery;
• and
• a refrigerant circulation path through which the refrigerant is circulatable;
• a power electronics cooling subsystem thermally connected to the HVAC subsystem, the power electronics cooling subsystem comprising a power electronics coolant circulation path through which a power electronics coolant circulates;
• and
• a heat exchanger thermally connecting the HVAC subsystem and the power electronics cooling subsystem, the heat exchanger comprising a first passage fluidly connected to the refrigerant circulation path and a second passage fluidly connected to the power electronics coolant circulation path,
• wherein the first control valve includes an inlet port communicating with an outlet of the compressor, a first outlet port communicating with the interior condenser, and a second outlet port communicating with an inlet of the warm-up line,
• wherein the refrigerant passage of the battery is fluidly connected to the distribution line,
• wherein the refrigerant passage of the battery is thermally separated from the power electronics cooling subsystem, and
• wherein an outlet of the warm-up line communicates with an inlet of the battery.
