[0003] The existing household split variable frequency air conditioner has a power reduction function, and users can set different power reduction gears to control the running power of the air conditioner. The function mainly controls the running current of the compressor, and then limits the running frequency, and finally achieves the purpose of reducing the running power of the air conditioner. The basic principle is based on the compressor output power formula P=UxI, that is, under the condition that the power supply voltage is basically stable, the compressor running frequency is indirectly controlled by setting the current upper limit value or the given running power threshold, thereby limiting the power output of the air conditioner, but because the compressor running current limit value corresponding to different power reduction gears is a fixed value, the compressor running power adjustment range is relatively limited in actual operation, which not only reduces the flexibility of running power adjustment, but also wastes electricity and increases energy consumption to a certain extent.

[0030] Referring to Figure 1 , Figure 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present application. The control method of the air conditioner will be described in detail below. As shown in Figure 1 , the method comprises the following steps S110-S120.

[0031] S110, acquiring a set temperature, an operation mode and a set power consumption.

[0032] In the embodiment of the present application, after the air conditioner starts and enters the power reduction operation mode, the control system of the air conditioner first acquires and obtains a plurality of key operation parameters in real time. These parameters include: the target temperature set by the user through the remote controller or the APP in advance, i.e. the set temperature T 设 ; the current working operation mode of the air conditioner, such as the cooling mode or the heating mode; and the expected power consumption target value set by the user, i.e. the set power consumption, which includes the set cooling power consumption Q 功耗 1 and the set heating power consumption Q 功耗 2. Understandably, the set cooling power consumption Q 功耗 1 is the power consumption set by the air conditioner in the cooling mode, and the set heating power consumption Q 功耗2 2 is the power consumption set by the air conditioner in the heating mode.

[0033] S120, adjusting the running current of the compressor corresponding to the current power reduction gear according to the set temperature, the operation mode, the set power consumption and the acquired indoor environment temperature to obtain an adjusted running current, and controlling the air conditioner according to the adjusted running current.

[0034] In the embodiment of the present application, the indoor environment temperature includes a first indoor environment temperature and a second indoor environment temperature, and the adjusted running current includes a first adjusted running current and a second adjusted running current, as Figure 2As shown, step S110 specifically includes steps S111-S114: S111, determining whether the first power adjustment condition is met based on the set temperature, the operating mode, the set power consumption, and the acquired first indoor ambient temperature; S112, if the first power adjustment condition is met, adjusting the operating current of the compressor corresponding to the current power reduction setting to obtain the first adjustable operating current, and controlling the air conditioner based on the first adjustable operating current; S113, determining whether the second power adjustment condition is met based on the first indoor ambient temperature, the operating mode, the set power consumption, and the acquired second indoor ambient temperature; S114, if the second power adjustment condition is met, adjusting the first adjustable operating current to obtain the second adjustable operating current of the compressor, and controlling the air conditioner based on the second adjustable operating current. Specifically, after the air conditioner starts and enters the power reduction operating mode, the operating parameters collected in real time by the control system also include: the first indoor ambient temperature T detected in real time by the indoor ambient temperature sensor. 内环1 First indoor ambient temperature T 内环 1. Set temperature T 设 The operating mode and set power consumption together form the decision-making basis for the air conditioner's dynamic power adjustment logic. The control system will adjust the power based on the first indoor ambient temperature T. 内环1 Set temperature T 设 The system determines whether to trigger subsequent power adjustment steps by checking if the operating mode and set power consumption meet the first power adjustment condition. Understandably, when using an air conditioner, in addition to setting the set temperature T... 设 The system can also set the operating mode and power consumption, as well as a power reduction level. The operating current corresponding to the power reduction level can be obtained based on the set power reduction level.

[0035] In this embodiment, such as Figure 3 As shown, step S111 specifically includes steps S1111-S1114:

[0036] S1111: Obtain the first indoor ambient temperature;

[0037] S1112. If the operating mode is cooling mode, the first cooling temperature difference is obtained by calculating the difference between the first indoor ambient temperature and the set temperature.

[0038] S1113. If the operating mode is heating mode, then the difference between the set temperature and the first indoor ambient temperature is calculated to obtain the first heating temperature difference.

[0039] S1114. Detect whether the first power adjustment condition is met based on the operating mode, the set power consumption, and the first cooling temperature difference or the first heating temperature difference.

[0040] In the embodiment of the present application, after the air conditioner starts and enters the power-reduced operation mode set by the user, the control system first collects the first indoor environment temperature, and according to the operation mode, enters different temperature difference calculation logic branches: if the current operation mode is the cooling mode, the difference between the first indoor environment temperature and the set temperature is calculated to obtain the first cooling temperature difference; if the current operation mode is the heating mode, the difference between the set temperature and the first indoor environment temperature is calculated to obtain the first heating temperature difference. Then, the control system comprehensively analyzes and judges the calculated first cooling temperature difference or first heating temperature difference, the operation mode and the set power consumption to detect and determine whether the first power adjustment condition is met, i.e., whether the first power adjustment condition is met. It should be noted that step S1114 specifically comprises: if the first cooling temperature difference is not greater than the first cooling temperature difference threshold or the first heating temperature difference is not greater than the first heating temperature difference threshold, the first cumulative power consumption and the first running time of the air conditioner are obtained; and whether the first power adjustment condition is met is detected according to the operation mode, the first cumulative power consumption, the first running time and the set power consumption. It should also be noted that the set power consumption includes the set cooling power consumption and the set heating power consumption, and whether the first power adjustment condition is met is detected according to the operation mode, the first cumulative power consumption, the first running time and the set power consumption, which specifically comprises: if the operation mode is the cooling mode, the product of the set cooling power consumption and the first running time is calculated to obtain the first cooling target power consumption; if the operation mode is the heating mode, the product of the set heating power consumption and the first running time is calculated to obtain the first heating target power consumption; and if the first cumulative power consumption is greater than the first cooling target power consumption or the first cumulative power consumption is greater than the first heating target power consumption, it is determined that the first power adjustment condition is met. For easy understanding, it is assumed that the first cooling temperature difference threshold is a, the first heating temperature difference threshold is m, the first cumulative power consumption is Q 耗电量 1, the first running time is T 运行1 , the first cooling temperature difference is T 内环1 -T 设 , the first heating temperature difference is T 设 -T 内环1 , when the air conditioner is in the cooling mode, if T 内环1 -T 设 ≤a, the first cumulative power consumption Q 耗电量1 and the first running time T 运行1 are obtained, and the first cooling target power consumption Q 功耗1 *T 运行 1 is calculated; when the air conditioner is in the heating mode, if T 设 -T 内环1If ≤m, then the first cumulative power consumption is Q. 耗电量 1 and the first run duration is T 运行1 Calculate the power consumption for the first heating target as Q. 功耗2 *T 运行1 When Q 耗电量 1 > Q 功耗 1*T 运行1 Or Q 耗电量 1 > Q 功耗 2*T 运行1 If so, then the first power adjustment condition is determined to be met.

[0041] Further, after satisfying the first power adjustment condition, the operating current of the compressor corresponding to the current power reduction setting is lowered by a first current adjustment value to obtain the first adjusted operating current, wherein the first current adjustment value is I1; the air conditioner is controlled to operate according to the first adjusted operating current. Understandably, if we assume the current power reduction setting is D... 档 The corresponding compressor operating current is I. 档 Then the first regulating operating current I 档调1 =I 档 -I1. It should be noted that the air conditioner's control system operates according to the adjusted first regulating current I. 档调1 Adjusting the compressor's operating frequency reduces its operating power, thereby lowering the air conditioner's power consumption and achieving energy savings. It should also be noted that the first current adjustment value I1 differs for different power reduction levels, limiting the adjusted operating current value for each level. This effectively prevents the compressor's operating current from becoming too low, improving user comfort.

[0042] Furthermore, such as Figure 4 As shown, step S113 specifically includes steps S1131-S1136: S1131, obtaining the second indoor ambient temperature; S1132, if the operating mode is cooling mode, calculating the difference between the first indoor ambient temperature and the obtained second indoor ambient temperature to obtain a second cooling temperature difference; S1133, if the operating mode is heating mode, calculating the difference between the second indoor ambient temperature and the first indoor ambient temperature to obtain a second heating temperature difference; S1134, if the second cooling temperature difference is not greater than a second cooling temperature difference threshold or the second heating temperature difference is not greater than a second heating temperature difference threshold, obtaining the second cumulative power consumption and the second operating time of the air conditioner; S1135, calculating the product of the set power consumption and the second operating time according to the operating mode to obtain a second target power consumption; S1136, if the second cumulative power consumption is greater than the second target power consumption, determining that the second power adjustment condition is met. Specifically, assuming the obtained second indoor ambient temperature is T... 内环2, the second cooling temperature difference threshold value is b, the second heating temperature difference threshold value is n, when the air conditioner is in the cooling mode, the calculated second cooling temperature difference is T 内环1 -T 内环2 , when the air conditioner is in the heating mode, the calculated second heating temperature difference is T 内环2 -T 内环 1, if T 内环1 -T 内环2 ≤b or T 内环2 -T 内环1 ≤n, then the second cumulative power consumption Q 耗电量 2 of the air conditioner is obtained 运行2 2 and the second running time T 功耗1 2, if the running mode is the heating mode, then the second target power consumption = Q 运行 2*T 功耗 2, if the running mode is the cooling mode, then the second target power consumption = Q 运行2 2*T 耗电量 , if Q 功耗 2>Q 运行2 1*T 耗电量2 or Q 功耗2 2>Q 运行2 , then it is determined that the second power adjustment condition is met. It should be noted that, in the embodiment, the second cumulative power consumption Q 耗电量 2 is the power consumption accumulated on the basis of the first cumulative power consumption Q 耗电量 1, that is, the second cumulative power consumption Q 耗电量2 2 is greater than the first cumulative power consumption Q 耗电量1 1; the second running time T 运行2 2 is the running time accumulated on the basis of the first running time T 运行1 1, that is, the second running time T 运行2 2 is greater than the first running time T 运行1 1.

[0043] Still further, after the second power adjustment condition is met, the first adjusted running current is adjusted to the second adjusted running current of the compressor by a second current adjustment value, wherein the second current adjustment value is I2, and the air conditioner is controlled according to the second adjusted running current. Understandably, the second adjusted running current I 档调2 2 = I 档1 1-I2. It should be noted that the control system of the air conditioner adjusts the second adjusted running current I 档调2The compressor operation frequency is adjusted to reduce the compressor operation power, thereby reducing the operation power consumption of the air conditioner, and achieving the energy saving purpose. It should be noted that for different power reduction levels, the corresponding second current adjustment value I2 is different, so as to limit the adjusted operation current value of different power reduction levels, which can effectively avoid the compressor operation current being too low and improve the user's use comfort.

[0044] Figure 5 A flowchart of a control method of an air conditioner according to another embodiment of the present application is shown in FIG. 6. In this embodiment, the method comprises steps S110-S160. That is, in this embodiment, the method further comprises steps S130-S160 after step S120 of the above embodiment. Figure 5

[0045] S130, if the operation end instruction is received, the total cumulative power consumption Q and the total operation time T are obtained;

[0046] S140, the product of the set power consumption and the total operation time is calculated to obtain the total target power consumption;

[0047] S150, the quotient of the total cumulative power consumption and the total target power consumption is calculated to obtain the power consumption ratio;

[0048] S160, if the power consumption ratio is not greater than the preset power consumption ratio, the prompt information that the set power consumption is too high is sent.

[0049] In the embodiment of the present application, if the operation end instruction is received, the total cumulative power consumption Q 总耗电量 and the total operation time T 总运行 of the air conditioner are obtained; the product of the set power consumption and the total operation time is calculated to obtain the total target power consumption. Specifically, if the current mode is the cooling mode, the total target power consumption is Q 功耗1 *T 总运行 , and the power consumption ratio is Q 总耗电量 / (Q 功耗1 *T 总运行 ); if the current mode is the heating mode, the total target power consumption is Q 功耗2 *T 总运行 , and the power consumption ratio is Q 总耗电量 / (Q 功耗2 *T 总运行 ); if Q 总耗电量 / (Q 功耗1 *T 总运行 )≤0.8 or Q 总耗电量 / (Q 功耗2 *T 总运行 )≤0.8, the prompt information that the set power consumption is too high is sent, i.e. reminding the user to reduce the set power consumption and improve the energy saving performance in subsequent use; it can be understood that if Q​总耗电量 <Q 功耗1 *T 总运行 Or Q 总耗电量 <Q 功耗2 *T 总运行 The air conditioner's set power consumption remains unchanged.

[0050] Please see Figure 6 , Figure 6 This is a simplified flowchart illustrating a control method for an air conditioner according to an embodiment of the present invention. Figure 6 As shown, the user is using the air conditioner in cooling / heating mode, and the set temperature upon startup is T. 设 The user-defined power reduction setting triggers the control system to receive the compressor operating current limit I. 档 Control the operation of the air conditioner; the user inputs the power consumption setting, records the power consumption and running time of the air conditioner during operation; compare with the first indoor ambient temperature T 内环1 With the set temperature T 设 The refrigeration process meets T 内环1 -T 设 ≤a, the heating process satisfies T 设 -T 内1环 ≤m; Based on the comparison between the first cumulative power consumption and the first target power consumption (the first target power consumption includes the first cooling target power consumption and the first heating target power consumption), the compressor operating current I is adjusted. 档 Adjust to I 档1 The control system is adjusted according to I 档1 Adjust the compressor operating frequency; continuously monitor and compare the second indoor ambient temperature (T). 内环2 With the first indoor ambient temperature T 内环1 The refrigeration process meets T 内环1 -T 内环2 ≤b, the heating process satisfies T 内环2 -T 内环1 ≤n; Based on the comparison between the second cumulative power consumption and the second target power consumption, the first regulating operating current I of the compressor is adjusted. 档1 Adjust to the second regulating operation circuit I 档2 The control system is adjusted according to I 档2 Adjust the compressor's operating frequency.

[0051] Please see Figure 7 , Figure 7 This is a simplified flowchart illustrating a control method for an air conditioner when it is in cooling mode, according to an embodiment of the present invention. Figure 7 As shown, real-time monitoring and comparison of indoor ambient temperature changes are performed when T is met. 内环1 -T 设 ≤a, obtain the first cumulative power consumption and first running time of the air conditioner, if Q耗电量1 >Q 功耗1 *T 运行1 Then, for the compressor operating current I corresponding to the power reduction setting... 档 When I1 is lowered, the air conditioner's control system adjusts the first operating current I after the adjustment. 档调1 (I 档调1 =I 档 -I1) Adjust the compressor operating frequency to reduce the air conditioner's power consumption. The air conditioner continues cooling operation until T is met. 内环1 -T 内环2 ≤b, obtain the second cumulative power consumption and second operating time of the air conditioner, if Q 耗电量2 >Q 功耗1 *T 运行2 Then the first regulating operating current I will be adjusted. 档调1 When I2 is lowered, the air conditioner's control system adjusts the current I. 档调2 (I 档调2 =I 档调1 -I2) Adjust the compressor operating frequency to reduce the air conditioner's power consumption. When cooling operation ends, if Q... 总耗电量 <Q 功耗 1*T 总运行 The air conditioner continues to operate in its original state. If Q 总耗电量 / Q 功耗 1*T 总运行 ≤0.8 indicates a reminder to the user to reduce the set power consumption and improve energy efficiency in subsequent use. Specifically, assuming an initial indoor ambient temperature of 28℃, a set temperature of 20℃, and using the D3 power reduction setting, the compressor operates at a preset current limit of I. 档 The value is 8A. When the indoor ambient temperature is detected to drop to 24℃, the condition T is met. 内环1 -T 设 ≤4, if Q 耗电量1 >Q 功耗1 *T 运行 1. Compressor operating current limit I 档 The A is lowered by 2A, from 8A to 6A. The air conditioner's control system adjusts the compressor operating frequency to 6A. The air conditioner continues cooling operation. When the detected inner ambient temperature drops to 22℃, the T requirement is met. 内环1 -T 内环2 ≤2, Q 耗电量 2>Q 功耗 1*T 运行2 If the compressor operating current limit is reduced by 1.5A from 6A, then the second adjusted operating current is 4.5A. The air conditioner's control system adjusts the compressor operating frequency to 4.5A. It should be noted that the values ​​of a and b are set according to actual needs and are not specifically limited here.

[0052] Please see Figure 8 , Figure 8A flow chart of a control method of an air conditioner in a heating mode is provided for an embodiment of the present application. As shown in Figure 8 , the change of the indoor environment temperature is monitored in real time, and when T 设 -T 内环1 ≤m, the first cumulative power consumption and the first running time of the air conditioner are obtained, and if Q 耗电量 1>Q 功耗 2*T 运行1 , the compressor running current I 档 of the power reduction gear is lowered by I1, and the control system of the air conditioner adjusts the compressor running frequency according to the first adjusted running current I 档调1 (I 档调1 =I 档 -I1) to reduce the running power consumption of the air conditioner. The air conditioner continues to run in the heating mode, and when T 内环2 -T 内环1 ≤n, the second cumulative power consumption and the second running time of the air conditioner are obtained, and if Q 耗电量2 >Q 功耗2 *T 运行2 , the first adjusted running current I 档调1 is lowered by I2, and the control system of the air conditioner adjusts the compressor running frequency according to the current I 档调2 (I 档调2 =I 档调1 -I2) to reduce the running power consumption of the air conditioner. When the heating operation ends, if Q 总耗电量 Q 功耗 1*T 总运行 , the air conditioner remains in the original state, and if Q 总耗电量 / Q 功耗1 *T 总运行 ≤0.8, the user is reminded to reduce the set power consumption and improve the energy saving performance in the subsequent use. Specifically, it is assumed that the initial indoor environment temperature is 20℃, the set temperature is 28℃, and the D3 power reduction gear is used, and the compressor running preset current limit I 档 of this gear is 8A. When the indoor temperature is detected to be raised to 24℃, i.e., T 设 -T 内环1 ≤4, if Q 耗电量1 >Q 功耗1 *T 运行 1, the compressor running current limit I 档 is lowered by 2A from 8A to 6A, and the control system of the air conditioner adjusts the compressor running frequency according to 6A; the air conditioner continues to run in the heating mode, and when the indoor temperature is detected to be raised to 26℃, i.e., T 内环2 -T 内环1 ≤2, Q 耗电量2 >Q 功耗1 *T 运行2If m=1 and n=1, then the compressor operating current limit is lowered by 1.5A from 6A, i.e. the second adjusted operating current is 4.5A. The control system of the air conditioner adjusts the compressor operating frequency according to 4.5A. It should be noted that the values of m and n are set according to actual requirements, which are not specifically limited here.

[0053] In summary, the first adjusted operating current is obtained by adjusting the operating current of the compressor corresponding to the current power reduction gear according to the first indoor environment temperature, the set temperature, the operating mode and the set power consumption; the air conditioner continues to operate in the cooling or heating mode, and then the second adjusted operating current is obtained by adjusting the first adjusted operating current according to the second indoor environment temperature, the first indoor environment temperature, the operating mode and the set power consumption, i.e. the operating current of the air conditioner is adjusted in stages, which not only improves the flexibility of the operating power adjustment of the air conditioner, but also effectively saves energy consumption.
