The invention discloses a vehicle air conditioner refrigeration system and a control method thereof, and the control method comprises the following steps: controlling a refrigerant main path to work according to a vehicle refrigeration working mode; if the working mode is a cockpit single-refrigeration mode or a cockpit and power battery dual-refrigeration mode, an electronic switch valve is controlled to be switched on, so that a cockpit refrigerant branch is in a working state; if the working mode is a power battery single-refrigeration mode or a cockpit and power battery dual-refrigeration mode, an electronic opening valve is controlled to be opened, so that a power battery refrigerant branch is in a working state; and the power battery cooling water channel is controlled to be in a working state. According to the control method, multiple working modes of a single refrigeration mode of the cockpit, or a dual refrigeration mode of the cockpit and the power battery and a single refrigeration mode of the power battery can be realized, and the air conditioner refrigeration system can be controlled according to different working modes.

    本发明公开了一种车辆空调制冷系统及其控制方法,其中所述的控制方法包括如下:根据车辆制冷工作模式,控制冷媒总路进行工作;若工作模式为驾驶舱单制冷模式、或驾驶舱和动力电池双制冷模式,控制电子开关阀开通,使得驾驶舱冷媒支路处于工作状态;若工作模式为动力电池单制冷模式、或驾驶舱和动力电池双制冷模式、控制电子开度阀的开通,使得动力电池冷媒支路处于工作状态;还控制动力电池冷却水路处于工作状态。本发明所述控制方法可以实现驾驶舱单制冷模式、或驾驶舱和动力电池双制冷模式、动力电池单制冷模式的多种工作模式,并可以根据不同的工作模式对空调制冷系统进行控制。
