The invention relates to the technical field of rail transit (subway) vehicle air conditioner design and manufacturing, in particular to a heat pump air conditioner system and a control method thereof. The heat pump air conditioning system comprises a first system and a second system which work independently, a first outdoor heat exchanger and a second outdoor heat exchanger are connected in parallel, and a third outdoor heat exchanger and a fourth outdoor heat exchanger are connected in parallel; the first outdoor heat exchanger is serially connected with the first indoor heat exchanger; the second outdoor heat exchanger is serially connected with the second indoor heat exchanger; the third outdoor heat exchanger is serially connected with the first indoor heat exchanger, and the fourth outdoor heat exchanger is serially connected with the second indoor heat exchanger. The invention further provides a control method of the heat pump air conditioning system. The control method of the heat pump air conditioning system is applied to the heat pump air conditioning system. Compared with the prior art, the system has the advantages that the first system and the second system can alternately operate in a refrigerating and heating mode, the indoor temperature of the rail transit vehicle is kept stable, and the experience feeling of passengers is improved.

    本发明涉及轨道交通(地铁)车辆空调设计与制造技术领域,特别是涉及一种热泵空调系统及其控制方法。该热泵空调系统包括独立工作的第一系统和第二系统,第一室外换热器和第二室外换热器并联连接,第三室外换热器和第四室外换热器并联连接;第一室外换热器与第一室内换热器串联连接,第二室外换热器与第二室内换热器串联连接;第三室外换热器与第一室内换热器串联连接,第四室外换热器与第二室内换热器串联连接。本发明还提供一种热泵空调系统控制方法,该热泵空调系统控制方法应用于上述热泵空调系统。现有技术相比,本发明的优点在于:实现了第一系统和第二系统可以制冷制热交替运行,进而保持轨道交通车辆室内温度稳定而提升乘客体验感。
