A vehicle thermal management system, may include an HVAC subsystem including a first compressor and a first refrigeration cycle including a first refrigerant loop fluidly connected to the first compressor; 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 the downstream side of the second compressor, and a second refrigerant loop fluidly connected to the condenser; a refrigerant chiller mounted between the first refrigeration cycle and the second refrigeration cycle 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. The condenser of the second refrigeration cycle is thermally connected to at least one of the battery coolant loop and the powertrain coolant loop.

Vehicle thermal management system

A method of controlling an automotive air-conditioning system includes compressing a refrigerant by sensing the operation of an air conditioner while a vehicle is driven after starting an engine of the vehicle, circulating the cooling water cooled by exchanging heat with external air in the cooling module to cool the intercooler or the electric device, and controlling operation speeds of a water pump in the cooling system and of a cooling fan, while keeping the vehicle idling or running, and ending the control by determining whether vehicle speed, pressure of the air conditioner, temperature of the cooling water, and temperature of the intercooler or the electric device are within predetermined values.
