摘要： A thermal control system includes first and second components. A plurality of coolant conduits fluidly couple the components to define a coolant circuit. A pump is operable to circulate coolant among the conduits. Within the coolant circuit, the first component is upstream of the second component and the pump is upstream of the first component. A controller is configured to selectively operate according to a circuit heating mode, wherein the controller controls the pump at a first speed and controls the first respective component as a thermal source, and a local heating mode, wherein the local heating mode the control controls the pump at a second speed and controls the first respective component as a thermal source. The second speed is less than the first speed. The controller operates in the local heating mode in response to a heating request associated with the second respective component.

摘要： A thermal management method and system in a vehicle include a chiller to cause heat transfer between a coolant loop that defines a path in which a coolant circulates and a refrigerant loop that defines a path in which a refrigerant circulates. The system includes an electronic expansion valve (EXV) in the refrigerant loop to control a flow of the refrigerant into a first part of the chiller, and a coolant pump in the coolant loop to control a flow of the coolant into a second part of the chiller. A controller controls the EXV and the coolant pump based on a target amount for the heat transfer.
