Thermal management in a vehicle involves a compressor to output a refrigerant in vapor form for circulation in a refrigerant loop. A thermal management system includes a heating, ventilation, and air conditioning (HVAC) system in the refrigerant loop including an evaporator and an HVAC condenser, and an exterior condenser in the refrigerant loop configured to vent heat to an exterior of the vehicle. A first variable refrigerant flow valve (RFV) controls a flow rate of the refrigerant output by the compressor into the HVAC condenser, and a second RFV controls a flow rate of the refrigerant output by the compressor into the exterior condenser. A controller controls the first RFV and the second RFV based on a target output temperature for the HVAC condenser.

    车辆中的热管理包括压缩机以蒸汽形式输出制冷剂,用于在制冷剂回路中循环。一种热管理系统,包括制冷剂回路中的加热、通风和空调(HVAC)系统,该系统包括蒸发器和HVAC冷凝器,以及制冷剂回路中的外部冷凝器,该外部冷凝器被配置成将热量排放到车辆外部。第一可变制冷剂流量阀(RFV)控制压缩机输出到HVAC冷凝器中的制冷剂的流量,第二RFV控制压缩机输出到外部冷凝器中的制冷剂的流量。控制器基于HVAC冷凝器的目标输出温度控制第一RFV和第二RFV。
