The present invention provides a vehicle air-conditioning system and a control method thereof, the vehicle air-conditioning system comprising a secondary refrigerant cycle and a refrigerant cycle provided outside a passenger space of a vehicle and having cooling and heating functions, the refrigerant circulation comprises a compressor, a four-way valve, a first heat exchanger, a throttling element and a second heat exchanger which are sequentially connected through pipelines, and the secondary refrigerant circulation comprises a first fluid pump and an in-vehicle heat exchange part located in the passenger space. And a secondary refrigerant in the secondary refrigerant circulation can exchange heat with a refrigerant circulating in the second heat exchanger at the second heat exchanger and then enter the in-vehicle heat exchange component under the driving of the first fluid pump to adjust the temperature of the passenger space. Potential safety hazards and the like possibly existing due to vehicle refitting are completely eradicated, meanwhile, the vehicle air conditioning system is more reasonable and simpler in design, and the vehicle cost can be reduced.

    本发明提供一种车用空调系统及其控制方法,车用空调系统包括载冷剂循环以及被设置于车辆的乘人空间之外的且具备制冷与制热功能的制冷剂循环,其中,所述制冷剂循环包括顺次管路连接的压缩机、四通阀、第一换热器、节流元件及第二换热器,所述载冷剂循环包括第一流体泵及处于所述乘人空间内的车内换热部件,所述载冷剂循环内的载冷剂能够在所述第二换热器处与所述第二换热器内流通的制冷剂换热后在所述第一流体泵的驱动下进入所述车内换热部件内对所述乘人空间进行调温。本发明杜绝由于车辆改装可能存在的安全等隐患,同时本发明的车用空调系统设计更加合理、简单,能够降低车辆成本。
