Abstract

The invention relates to the technical field of air conditioners, and discloses an air conditioner control method and device, an air conditioner and a storage medium. The method comprises the steps that when the air conditioner is in a refrigeration mode, the current operation frequency of a compressor is obtained; when the current operation frequency reaches the minimum limiting frequency, whether the indoor temperature of the indoor environment where the air conditioner is located is smaller than the set temperature or not is judged; and when the indoor temperature of the indoor environment where the air conditioner is located is smaller than the set temperature, the opening degree of a first electronic expansion valve is increased, and the opening degree of a second electronic expansion valve is reduced, so that the refrigerant pressure between an outdoor heat exchanger and a flash evaporator is reduced, the refrigerant flow at an indoor heat exchanger is reduced, and therefore liquid refrigerant entering the indoor heat exchanger is decreased, the output cooling load of the air conditioner can better meet the actual requirement, the condition the compressor of the air conditioner maintains the stable indoor temperature in a non-stop state is ensured, meanwhile, the risk of liquid return is reduced, the system reliability is enhanced, and the purpose of improving the comfort of a user is achieved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device, an air conditioner and a storage medium. Background technique [0002] At present, when the air conditioner is in cooling operation, in the middle of the night or when the temperature difference is small, the operating frequency of the air conditioner will be reduced due to the low indoor and outdoor cooling and heating loads. The load still causes the indoor temperature to continue to drop until it reaches or is lower than the user's set temperature, which will cause the temperature to stop. However, after the temperature is stopped, the indoor temperature will gradually rise until it is higher than the user's set temperature. , in this way, the air conditioner will frequently reach the temperature and shut down during the cooling operation. However, the frequent shutdown of the air conditioner will cause the indoor ...
