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.
