The invention provides a temperature adjusting method and device based on a vehicle-mounted heat pump air conditioning system and a storage medium. The method comprises the steps that under the condition that the vehicle-mounted heat pump air conditioning system is in a passenger compartment dehumidification mode, the rotating speed of a compressor in the vehicle-mounted heat pump air conditioning system is adjusted according to the temperature difference between the target water outlet temperature and the actual water outlet temperature of a PTC heating unit so as to control the temperature difference to reach the target temperature difference; according to the temperature difference and the intervention state of the PTC heating unit, the opening degree of a three-way proportional valve of the passenger compartment is adjusted, and the intervention state includes that the PTC heating unit intervenes auxiliary heating on the passenger compartment and does not intervene auxiliary heating on the passenger compartment; and according to the temperature difference, determining a proportionality coefficient used for carrying out proportional-integral (PI) control on the PTC heating unit, and adjusting the output of the PTC heating unit by utilizing the proportionality coefficient so as to control the opening or closing of the PTC heating unit, so that the water temperature is adjusted. The electric energy consumption can be reduced, the energy-saving effect of the heat pump air conditioning system is improved, and therefore the cruising ability of the vehicle is improved.

    本申请提供一种基于车载热泵空调系统的温度调节方法、装置及存储介质。该方法包括:在车载热泵空调系统处于乘员舱除湿模式的情况下,根据PTC加热单元的目标出水温度与实际出水温度之间的温差,对车载热泵空调系统中的压缩机的转速进行调整,以控制温差达到目标温差;根据温差以及PTC加热单元的介入状态,对乘员舱三通比例阀的开度进行调节,介入状态包括PTC加热单元对乘员舱介入辅热和未对乘员舱介入辅热;根据温差确定用于对PTC加热单元进行比例积分PI控制的比例系数,利用比例系数对PTC加热单元的输出进行调节,以控制PTC加热单元的开启或关闭,以便对水温进行调节。本申请能够降低电能消耗,提升热泵空调系统的节能效果,从而提升车辆续航能力。
