The invention relates to the technical field of electric vehicle heat pump air conditioner temperature control, discloses an electric vehicle heat pump air conditioner temperature control method, andsolves the problem that the control mode of an electric vehicle heat pump air conditioner in a refrigerating and heating mode easily influences the comfort experience of passengers in the traditionaltechnology. The method comprises steps: in the refrigeration mode, the working rotating speed of a compressor is limited according to the environment temperature, the working rotating speed of the compressor is adjusted according to the difference value between the actual temperature of a passenger compartment and the set temperature, and whether the working rotating speed of the compressor is adjusted or not is judged according to the difference value between the air conditioner air outlet temperature and the set temperature; in the heating mode, the difference value between the current indoor temperature and the set temperature is considered, whether the temperature of the air outlet reaches the standard or not is considered, and then the working rotating speed of the compressor and therotating speed of the indoor air blower are adjusted. The control method is suitable for controlling the heat pump air conditioner of the electric automobile in the refrigerating and heating modes.

    本发明涉及电动汽车热泵空调温度控制技术领域,公开了一种电动汽车热泵空调温度控制方法,解决传统技术中在对电动汽车热泵空调在制冷、制热模式下的控制方式容易影响乘客舒适性体验的问题。本发明的方案概括为:在制冷模式下,根据环境温度对压缩机工作转速进行限制,根据乘员舱实际温度和设定温度的差值对压缩机工作转速进行调整,根据空调出风口温度和设定温度的差值判断是否调整压缩机的工作转速;在制热模式下,除了考虑当前室内温度与设定温度的差值,还要考虑出风口温度是否达标,进而对压缩机工作转速进行调整和室内鼓风机转速进行调整。本发明适用于对电动汽车热泵空调在制冷、制热模式下的控制。
