The historical indoor temperature is the indoor temperature acquired before, and the temperature control capacity of the current air conditioner can be known by comparing the newly acquired indoor temperature with the historical indoor temperature. The temperature control capability of the air conditioner is improved when the temperature control capability is insufficient by balancing the current temperature control difficulty and the current temperature control capability of the air conditioner.

Therefore, step S20 is continuously executed, the temperature reduction process is completed by continuously controlling the frequency of the compressor, so that the actual temperature reduction trend is kept gentle, thereby avoiding the uncomfortable feeling caused to the user by sudden changes of the indoor temperature, and the gentle temperature reduction trend also increases the time of the low-frequency operation of the compressor, thereby achieving the effect of operating energy conservation.
When the newly acquired indoor temperature is not greater than the target temperature, proceeding to step S50;
and step S50, adjusting the operating frequency of the compressor to maintain the indoor temperature at the target temperature.

Therefore, step S232 is executed, the refrigeration efficiency of the air conditioner can be improved by increasing the operating frequency of the compressor, so that the actual cooling trend can be in an ideal state, the problem of unsatisfactory indoor cooling effect caused by insufficient cooling capacity of the air conditioner due to overhigh outdoor temperature is avoided, and the cooling effect of the air conditioner is ensured.
In this embodiment, the upper limit of the operating frequency of the compressor is 90 Hz.
When the actual cooling value is not less than the cooling standard value, the step S233 is entered;
step S233, the operating frequency of the compressor is maintained.
The fact that the newly acquired actual cooling value is not less than the cooling standard value shows that the cooling capacity of the current air conditioner can cope with the cooling work of the indoor temperature at the current outdoor temperature. Therefore, step S233 is executed to keep the current operating frequency of the compressor.
In this embodiment, through the size of comparison actual cooling value and cooling standard value, directly judge whether the air conditioner is that the cooling ability can satisfy the requirement of user to indoor cooling, when the air conditioner can not satisfy indoor cooling requirement, improve the operating frequency of air conditioner compressor and improve the cooling ability of air conditioner, guarantee the cooling effect of air conditioner.

when the newly acquired indoor temperature is less than the target temperature, the process proceeds to step S20;
when the newly acquired indoor temperature is less than the target temperature, the process proceeds to step S20;

Therefore, step S20 is continuously executed, the temperature rising process is completed by continuously controlling the compressor frequency, so that the actual temperature rising trend is kept gentle, thereby avoiding the uncomfortable feeling to the user caused by sudden changes of the indoor temperature, and the gentle temperature rising trend also increases the time of the low-frequency operation of the compressor, thereby achieving the effect of saving energy in operation.
When the newly acquired indoor temperature is not less than the target temperature, the process proceeds to step S80;
and step S80, adjusting the operating frequency of the compressor to maintain the indoor temperature at the target temperature.

The standard temperature rise value is a standard temperature rise value of the air conditioner within a corresponding outdoor temperature range within standard time and is reduced along with the decreasing of the external temperature. In the embodiment, when the outdoor temperature is more than 10 ℃, the standard temperature rise value is 0.5 ℃; when the outdoor temperature is within the range of 5-10 ℃, the standard temperature rise value is 0.3 ℃; when the outdoor temperature is less than 5 ℃, the standard temperature rise value is 0.2 ℃.
