The invention is suitable for the technical field of automobiles, and provides a control method and device of a heat pump air conditioning system, a storage medium and a vehicle. The control method of the heat pump air conditioning system comprises the steps that the current exhaust temperature and the current exhaust pressure of the heat pump air conditioning system are obtained; determining a current temperature grade to which the current exhaust temperature belongs in a plurality of preset temperature grades, and determining a current pressure grade to which the current exhaust pressure belongs in a plurality of preset pressure grades; according to the current temperature grade and the current pressure grade, the opening degree of an electronic expansion valve of the heat pump air conditioning system is adjusted to the target opening degree, the target opening degree is larger than or equal to the first opening degree, and the first opening degree is obtained according to the optimal exhaust pressure of the heat pump air conditioning system; the optimal exhaust pressure is related to the refrigerant temperature on the outlet side of the air cooler. According to the embodiment of the invention, the heat pump air conditioning system can run in a high energy efficiency interval, and the purpose of saving energy is achieved.
