In practical applications, the defined types of the frequency control areas include a frequency reduction control area and a frequency maintenance area, and the types are determined according to the comparison result between the total current of the household power and the current threshold of each frequency control area.

When the type of the frequency control area where the current household electricity is located is judged to be the frequency reduction control area according to the total current of the household electricity, in practical application, the frequency reduction control area comprises a fast frequency reduction area and a slow frequency reduction area in terms of frequency reduction speed, so that the air conditioner is controlled to operate at a reduced frequency at a set frequency reduction speed of the frequency reduction control area when a frequency threshold value based on the frequency reduction control area is obtained based on the current frequency reduction control area. Further, when the air conditioner is controlled to operate at a reduced frequency, the type of the frequency control area where the total current of the household power supply is located is detected, and when the air conditioner is located in the frequency reduction control area, if the frequency control area where the total current of the household power supply is located cannot be adjusted through frequency reduction, the control mode that the air conditioner is subjected to frequency reduction to a preset value is also involved, so that when the type of the frequency control area is determined to be the frequency reduction control area, the frequency control parameters of the frequency reduction control area are obtained, and the air conditioner is controlled to operate according to the frequency control parameters, and then the method further comprises the following steps:

Referring to fig. 4, fig. 4 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention. Based on the first embodiment shown in the above method, before the step of obtaining the current total current of the household power when the air conditioner is started, the method further includes:
step S40, when receiving an air conditioner starting instruction, acquiring the current household electricity total current;
and when receiving a starting instruction of the air conditioner, determining whether the air conditioner can be normally started or not at present based on the current total household electricity current. In practical application, the total current of the current household electricity is obtained according to the received starting instruction of the air conditioner, and the electricity utilization functional area where the current household electricity is located is judged according to the key point of the household electricity.

Referring to fig. 5, fig. 5 is a flowchart illustrating a control method of an air conditioner according to a third embodiment of the present invention. Based on the first and second embodiments shown in the method, the air conditioner control method further comprises
Step S70, setting a function control area based on the current household electricity based on the set rated current value;
in step S80, a current threshold is set for each set function control region.
In this embodiment, the current threshold in the set function control region may be set to a rated current value according to the household air switch characteristics, and function control regions based on the numerical regions of the rated current value are set respectively according to the rated current value, and the related function region settings may refer to fig. 6, where fig. 6 is the set household electricity function regions, and each region is defined as a function control region according to the numerical value of the rated off current, for example, in fig. 6, a is defined as an immediate shutdown region; BC are all defined as a frequency reduction area; d is defined as a hold frequency region; e is defined as the normal operating region. In addition, the rated current value is a rated household current off value set based on the current air switch characteristic. As shown in fig. 6, when the rated current value d0 is defined, a frequency holding region is provided below the rated value, and a fast down region, a slow down region, and an immediate off region are provided above the rated value. As shown in fig. 6, the lower limit value dk of the frequency holding range is multiplied by a factor smaller than 1, for example, 0.92, based on the rated value d 0.
Or, when the functional area is set, another scheme is designed according to the lowest operable required current value of the air conditioner and the rated value of the household air switch. Assuming that the minimum possible operation required current value of the air conditioner is I0, dk may be set to d 0-I0; furthermore, the air conditioner is determined according to the required current value at the lowest sustainable air conditioner refrigerating capacity and the rated value of the household air switch. Assuming that the lowest cooling capacity of the sustainable air conditioner requires I1, dk may be set to d 0-I1. The upper limit value d1 of the slow down frequency region is determined according to the international standard of the air conditioner, at present, the same international standard is adopted by most countries in the world, and the national standard is basically consistent with the international standard. For example, if the international standard specifies that the air switch 1h cannot be turned off at 1.13 times the rated current, d1 may be d1 ═ d0 × k1, and k1 may be 1.13 or may be a value close to 1.13. The upper limit value d2 of the fast frequency-reducing region is a certain value greater than the lower limit value d1, and d2 may be d2 — d0 × k 2. If the national standard states that 1.45 times the current is necessary to open in an air switch 1h, typically, k2 takes a value between d1 and 1.45, but values greater than or equal to 1.45 are not excluded.
Furthermore, an embodiment of the present invention further provides a computer-readable storage medium, where an air conditioner control program is stored on the computer-readable storage medium, and when executed by a processor, the air conditioner control program implements the following operations:
