The running and parking integrated double-air-conditioning system comprises a heat exchanger, an oil return pipeline, a running air-conditioning compressor and a parking air-conditioning compressor, and the oil return pipeline comprises a first low-pressure branch pipe and a second low-pressure branch pipe; a first low-pressure branch pipe is communicated between the traveling air conditioner compressor and the heat exchanger and comprises a first pipeline, and a height difference exists between the first pipeline and the traveling air conditioner compressor, so that the first pipeline is higher than the joint of the first low-pressure branch pipe and the traveling air conditioner compressor; a second low-pressure branch pipe is communicated between the parking air conditioner compressor and the heat exchanger and comprises a second pipeline, and a height difference exists between the second pipeline and the parking air conditioner compressor so that the second pipeline can be higher than the connecting position of the second low-pressure branch pipe and the parking air conditioner compressor. According to the double-compressor system, when the running air conditioner compressor and the parking air conditioner compressor stop working and then work again, refrigerant oil can return along the original path, and the oil return problem of the double-compressor system is effectively solved.

    本申请涉及一种行驻一体式双空调系统及其车辆,其包括:换热器、回油管路、行车空调压缩机和驻车空调压缩机,回油管路包括第一低压支管和第二低压支管;行车空调压缩机与换热器之间连通有第一低压支管,第一低压支管包括第一管路,第一管路与行车空调压缩机之间具有一高度差,以使第一管路高于第一低压支管与行车空调压缩机连接处;驻车空调压缩机与换热器之间连通有第二低压支管,第二低压支管包括第二管路,第二管路与驻车空调压缩机之间具有一高度差,以使第二管路高于第二低压支管与驻车空调压缩机连接处。本发明中,当行车空调压缩机和驻车空调压缩机暂停工作后再次工作时,冷冻油会原路返回,有效解决双压缩机系统的回油问题。
