Abstract: A thermal management system for a vehicle includes a plurality of fluid flow circuits including a heating ventilation and air conditioning (HVAC) circuit circulating a flow of refrigerant therethrough and including an evaporator, a chiller heat exchanger, a first expansion valve located upstream of the evaporator, a second expansion valve located upstream of the chiller heat exchanger, and a heat exchanger located fluidly upstream of the expansion valves. A propulsion cooling circuit circulates a flow of coolant therethrough which is utilized to condition one or more propulsion components of the vehicle. The flow of coolant is directed through the heat exchanger, thus subcooling the flow of refrigerant. A controller is operably connected to one or more control points of the thermal management system and is configured to adjust the one or more control points to achieve a target amount of subcooling of the flow of refrigerant at the heat exchanger.

Abstract: A climate-control system for a vehicle, comprising a controller in communication with a chiller configured to cool a vehicle battery and an evaporator configured to cool a vehicle cabin. The controller is configured to output a target chiller-pump speed based upon a difference between a battery coolant temperature and a target-battery coolant temperature to mitigate a temperature swing of air entering the cabin, and limiting the target chiller-pump speed in response to an available capacity of the chiller.

Abstract: The present disclosure relates to a temperature control system of an electric vehicle. A circulation flow path includes 1st-4th and a high-temperature flow paths. A liquid temperature adjustment device is disposed on the first flow path. A compartment heat exchanger is communicated with the liquid temperature adjustment device through the first flow path, and communicated with a heat-dissipation device through the second flow path. A motor cooling circuit is communicated with the heat-dissipation device. A flow path switch is connected with a first inlet, a second outlet and a fourth outlet through the first flow path, the third flow path and the fourth flow path. The high-temperature flow path is bridged between the second flow path and the fourth flow path. The first flow path is selectively communicated with the third flow path or the fourth flow path by the flow path switch. Therefore, the issues and inconvenience are solved.

Abstract: A refrigerant/heat medium heat exchanger that heats a heat medium which circulates in a heater core of an HVAC unit is provided in a discharge pipe of a cooling refrigerant circuit, a heating bypass circuit that extends to a receiver is connected to a downstream side of the refrigerant/heat medium heat exchanger through a switching means, a second circuit having a second decompression means is provided between an outlet of the receiver and a first end of a vehicle exterior heat exchanger, and a third circuit having a solenoid valve is provided between a second end of the vehicle exterior heat exchanger and an intake circuit. In a vehicle air-conditioning system, a heating refrigerant circuit is configured by an electric compressor, a refrigerant/heat medium heat exchanger, a switching means, a heating bypass circuit, a receiver, a second circuit, a vehicle exterior heat exchanger, and a third circuit. Consequently, while simplification of a configuration and the like are attained by diverting cooling refrigerant circuit and an HVAC of a current system, cooling/heating capacity can be ensured by diversifying heating heat sources, and operation in a frost formation delay mode or the like is possible during heating.
