The invention relates to a system for air conditioning a vehicle interior while cooling a vehicle battery of an electric vehicle, comprising a first cooling circuit having a first heat exchanger for cooling the vehicle battery; a second cooling circuit having a second heat exchanger for air-conditioning the interior of the vehicle; at least one first compressor and at least one first condenser downstream of the first compressor; at least one first throttling element downstream of the first condenser and upstream of the first heat exchanger; at least one second throttling element upstream of the second heat exchanger. The first cooling circuit and the second cooling circuit are arranged such that a higher temperature and pressure of coolant is provided to the first heat exchanger compared to the second heat exchanger, and the pressure balancing element is used to reduce the pressure of the coolant of the first cooling circuit and/or to increase the pressure of the coolant of the second cooling circuit. The invention also relates to a method for air-conditioning a vehicle interior and simultaneously cooling a vehicle battery.
本发明涉及用于对车辆内部进行空气调节且同时冷却电动车辆的车辆电池的系统,包括具有用于冷却车辆电池的第一热交换器的第一冷却回路;具有用于对车辆内部进行空气调节的第二热交换器的第二冷却回路;至少一个第一压缩机和在第一压缩机下游的至少一个第一冷凝器;至少一个在第一冷凝器下游和在第一热交换器上游的第一节流元件;至少一个在第二热交换器上游的第二节流元件。第一冷却回路和第二冷却回路设置成使得与第二热交换器相比,向第一热交换器提供更高温度和更高压力的冷却剂,压力平衡元件用于降低第一冷却回路的冷却剂的压力和/或增加第二冷却回路的冷却剂的压力。本发明还涉及用于对车辆内部进行空气调节并且同时冷却车辆电池的方法。
