The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant to the air that has been conditioned and heat exchanged.
The compressor compresses a refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas, the discharged refrigerant gas flows into the condenser, the condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through a condensation process.
The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator may achieve a cooling effect by exchanging heat with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner may adjust the temperature of the indoor space throughout the cycle.

In this embodiment, when the user is not in the room, the air conditioner may be started in advance to perform indoor temperature adjustment, so that it is necessary to determine the expected return time of the user, the expected set temperature of the air conditioner at the expected return time, and the expected operation mode. The expected return time, the expected set temperature and the expected operation mode can be determined according to historical usage data of the air conditioner by the user, for example, the user often returns to home and starts the air conditioner in a certain time period, and the return time, the set temperature and the operation mode of the air conditioner of the next user can be predicted. In addition, the user may set the timed-on command in advance, where the timed-on command includes the timed-on time, the set temperature, and the operation mode, so that the predicted return time, the predicted set temperature, and the predicted operation mode may also be determined according to the timed-on command.

Optionally, the set wind speed may be determined according to historical usage data or a timing start command, and the skilled person may determine other set parameters according to actual needs, which does not affect the protection scope of the present application.
In this embodiment, when the current time is a first preset time from the expected return time, the air conditioner needs to be turned on, the first preset time is divided into a plurality of temperature adjustment times based on a preset number, the current time is the first temperature adjustment time in the temperature adjustment times, each temperature adjustment time and the expected return time form an arithmetic sequence based on a preset time interval, and then the target set temperature at each temperature adjustment time can be determined according to the outdoor temperature, the expected set temperature and the expected operation mode at the current time. Then, the air conditioner is started based on the expected operation mode, and when each temperature adjustment time is reached, the set temperature of the air conditioner is adjusted based on the target set temperature corresponding to each temperature adjustment time.

In addition, the air conditioner has a temperature setting range, and the target setting temperature cannot exceed the temperature setting range, so the target setting temperature is the maximum value when the target setting temperature is not less than the maximum value of the temperature setting range, and the target setting temperature is the minimum value when the target setting temperature is not more than the minimum value of the temperature setting range. Alternatively, the target set temperature, which is not an integer multiple of 0.5 degrees, is adjusted to a set temperature, which is an integer multiple of 0.5 degrees, that makes the air conditioner power consumption lower, in consideration of actual needs.
For reliable determination of the respective target set temperatures, in some embodiments of the application, the controller is specifically configured to:
determining a target set temperature at the current time according to the outdoor temperature, the expected set temperature and the expected operation mode;
