Generally, after the air conditioner starts the cooling mode or the heating mode, because the initial temperature of the indoor air is high or low, the temperature of the air blown out by the indoor unit after heat exchange will be relatively high or low accordingly. It can be seen that the air temperature at the beginning of the start-up of the air conditioner is usually difficult to meet the comfort experience of the user.
The related technology can enhance the outlet air temperature by reducing the heat exchange efficiency of the indoor unit, but the reduction of the heat exchange efficiency of the indoor unit will cause the risk of liquid shock to the compressor

[0137] Please refer to Figure 9 , the operation control method of the air conditioner in the first example includes the following steps:
[0138] S301, the air conditioner starts the cooling mode;
[0139] S302, control the air conditioner to enter the stage of increasing the temperature of the outlet air;
[0140] S303, controlling the electromagnetic two-way valve 153 to be in an open state;
[0141] S304, controlling the indoor fan 16 to run at the first rotational speed;
[0142] S305, control the compressor 11 to run at the first frequency;
[0143] S306, determine whether the operating duration of the air temperature enhancement stage is greater than or equal to a preset first duration threshold, if yes, go to step S307, if not, go to step S312;
[0144] S307, acquiring the indoor coil temperature according to a preset time interval;
[0145] S308, determine whether the indoor coil temperature is less than the preset first temperature threshold, if so, go to step S...

Abstract
The invention discloses an operation control method and device of an air conditioner, the air conditioner and a storage medium, the air conditioner comprises a compressor, a four-way valve, an outdoor heat exchanger, an indoor heat exchanger and a liquid impact prevention device, the liquid impact prevention device is arranged on a circulating flow path formed by the compressor, the four-way valve, the outdoor heat exchanger and the indoor heat exchanger; the method comprises the following steps that when the air conditioner enters an air outlet temperature enhancing stage, an indoor fan is controlled to operate at a first rotating speed, and a compressor is controlled to operate at a first frequency; and when the air conditioner quits the outlet air temperature enhancing stage, the air conditioner is controlled to enter a conventional operation stage from the outlet air temperature enhancing stage, the operation frequency of the compressor is adjusted to a second frequency, and the second frequency is smaller than the first frequency. The air outlet temperature of the air conditioner can be enhanced, the comfortable experience degree of a user is improved, and the risk of liquid impact of the compressor can be reduced.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to an operation control method of an air conditioner, a control device, an air conditioner and a storage medium. Background technique [0002] In the related art, most of the air conditioners blow the cold air or hot air after the heat exchange of the indoor unit into the room through the operation of the indoor fan, so as to cool or heat the room. Under normal circumstances, after the air conditioner starts the cooling mode or the heating mode, because the initial temperature of the indoor air is higher or lower, the temperature of the air blown out after the heat exchange of the indoor unit will be higher or lower accordingly. It can be seen from this that the air outlet temperature at the beginning of startup of the air conditioner is usually difficult to satisfy the user's comfort experience. In the related art, the outlet air temperature can be enhanced b...
