The invention relates to the technical field of heat pump air conditioner control, and discloses a control method for a vehicle heat pump air conditioning unit, which comprises the following control steps: acquiring the temperature in a vehicle, and determining the first output power of a compressor in the heat pump air conditioning unit according to the temperature in the vehicle; the vehicle speed and the remaining battery capacity of the power battery are obtained, the first output power is adjusted based on the vehicle speed and the remaining battery capacity of the power battery, and second output power is obtained; and the obtained second output power serves as the final output power of the compressor. The first output power of the compressor is subjected to order adjustment, so that the compressor compresses the refrigerant with the second output power, compared with the first output power, the second output power can better save the output power of the compressor, the energy consumption of the heat pump air conditioning unit is reduced, and meanwhile, the energy consumption of the heat pump air conditioning unit is reduced. The second output power is more accurate in control of the temperature of the refrigerant, and the temperature in the vehicle can be better maintained within the required range.

    本发明涉及热泵空调机控制技术领域,公开了一种车用热泵空调机组的控制方法,包括如下控制步骤:获取车内温度,根据车内温度确定热泵空调机组内压缩机的第一输出功率;获取车速和动力电池的剩余电池容量,并基于车速和动力电池的剩余电池容量对第一输出功率进行调整,得到第二输出功率;将所得到的第二输出功率作为压缩机的最终输出功率。本发明通过对压缩机的第一输出功率进行阶数调整,使得压缩机以第二输出功率对制冷剂进行压缩,第二输出功率相对于第一输出功率来说能够更好的节省压缩机的输出功率,降低热泵空调机组的能耗,同时,第二输出功率对于制冷剂的温度控制更加精准,能够更好的维持车内温度在所需范围。
