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.
一种车辆中的热管理方法和系统,包括冷却器,以造成限定冷却剂循环路径的冷却剂回路和限定制冷剂循环路径的制冷剂回路之间的热传递。该系统包括:制冷剂回路中的电子膨胀阀(EXV),以控制进入冷却器的第一部分中的制冷剂流量;以及冷却剂回路中的冷却剂泵,以控制进入冷却器的第二部分中的冷却剂流量。控制器基于热传递的目标量来控制EXV和冷却剂泵。
