Specifically, the energy-saving mode may be a default energy-saving mode set by the air conditioner when it leaves the factory, and the default energy-saving mode is configured with default configuration parameters, wherein the configuration parameters include the set temperature, the total running time, and the power consumption of the air conditioner value. For example, the default configuration parameters are: the set temperature is 26° C., the total running time is 8 hours, and the power consumption value of the air conditioner is 4 degrees. In addition, the energy-saving mode can also be set by the user before the air conditioner enters the energy-saving mode. The configuration parameters corresponding to the energy-saving mode can be set by the user through the preferred mode configured by the air conditioner. The configuration parameters of the fixed energy-saving mode are: the set temperature is 25°C, the total running time is 2 hours, and the power consumption value of the air conditioner is 1 degree.

In this embodiment, the preferred mode is set by an external device associated with the air conditioner. Correspondingly, when the air conditioner enters the energy-saving mode, before detecting whether the operating state of the air conditioner in the energy-saving mode satisfies the preset condition ,Also includes:

Receive the configuration parameters of the energy-saving mode, and determine the power value of the power consumption of the air conditioner in the energy-saving mode according to the configuration parameters, wherein the configuration parameters include the power value, the total running time, and the set temperature of the air conditioner.

Specifically, the configuration parameters are sent to the air conditioner by an external device associated with the air conditioner, where the external device may be a mobile phone, a tablet computer, and the like. The external device may be in the same local area network as the air conditioner, and directly send the received configuration parameters of the energy-saving mode to the air conditioner. The external device may also be connected to the air conditioner through the cloud, and send configuration parameters of the energy-saving mode to the air conditioner through the cloud. In this embodiment, the external device is loaded with an APP for controlling the air conditioner, is connected to the cloud through the APP, and then connected to the air conditioner through the cloud, so that the external device can receive energy-saving information through the APP. The configuration parameters corresponding to the mode, send the configuration parameters to the cloud, and then send the configuration parameters to the air conditioner through the cloud, so that when the air conditioner is turned off, the external device can also send the configuration parameters of the energy-saving mode to the cloud. The cloud temporarily stores the configuration parameters, and when it is detected that the air conditioner is turned on and connected to the cloud, the configuration parameters are sent to the air conditioner, so that the air conditioner configures an energy-saving mode according to the configuration parameters.

Further, the preset conditions are pre-set, and the preset conditions include that the duration of the air conditioner entering the energy-saving mode reaches the preset duration and the duration of the air conditioner entering the energy-saving mode does not reach the preset duration and the temperature difference is less than Preset temperature difference. The running state of the air conditioner in the energy-saving mode satisfies the preset condition that the running time of the air conditioner in the energy-saving mode reaches the preset time, or the running time of the air conditioner in the energy-saving mode does not reach the preset time but the temperature difference (indoor The temperature difference between the temperature and the set temperature) is less than the preset temperature difference. For example, if the time period during which the air conditioner enters the energy-saving mode reaches a preset time period, the operating state of the air conditioner entering the energy-saving mode satisfies a preset condition. For another example, if the operating time of the air conditioner in the energy saving mode does not reach the preset time but the temperature difference is greater, then the operating state of the air conditioner in the energy saving mode satisfies the preset condition.

At the same time, in this embodiment, the duration of the air conditioner entering the energy-saving mode refers to the continuous duration of the air conditioner in the energy-saving mode, that is, when the air conditioner enters the energy-saving mode, monitor the continuous duration of the air conditioner in the energy-saving mode, and compare the continuous duration with the preset duration. Compare to determine whether the time length for the air conditioner to enter the energy-saving mode reaches the preset time length; when the time length for the air conditioner to enter the energy-saving mode reaches the preset time length, it is determined that the operating state of the air conditioner entering the energy-saving mode meets the preset conditions; when the air conditioner enters the energy-saving mode When the duration does not reach the preset duration, the temperature difference between the indoor temperature and the set temperature is obtained, and the temperature difference is compared with the preset temperature difference. When the temperature difference is less than or equal to the preset temperature difference, it is determined that the air conditioner enters the The operating state of the energy-saving mode satisfies the preset condition, and when the temperature difference is greater than the preset temperature difference, it is determined that the operating state of the air conditioner entering the energy-saving mode does not meet the preset condition. For example, the preset time length is 20 minutes, and the preset temperature difference is 2°C. Correspondingly, the two situations in which the air conditioner enters the energy-saving mode and the operation state meets the preset conditions are respectively: the time period for the air conditioner to enter the energy-saving mode is longer than It is equal to 20 minutes, and the duration of the air conditioner entering the energy-saving mode is less than 20 minutes, and the temperature difference between the indoor temperature and the set temperature ΔT≤2°C.

S20. When the operating state of the air conditioner in the energy-saving mode satisfies the preset condition, acquire the environmental parameters corresponding to the air conditioner and the power value corresponding to the energy-saving mode, wherein the environmental parameters include outdoor temperature, indoor temperature, and air conditioner set temperature.

Specifically, the environmental parameters include outdoor temperature, indoor temperature, and set temperature of the air conditioner. The outdoor temperature can be detected by a temperature sensor installed on the outdoor unit of the air conditioner. The indoor temperature can be detected by a temperature sensor installed on the indoor unit. The sensor detects that the set temperature is the set temperature of the air conditioner corresponding to the energy-saving mode. Both the set temperature of the air conditioner and the power value are determined according to the configuration parameters corresponding to the energy-saving mode, that is, when the operating state of the air-conditioner in the energy-saving mode satisfies a preset condition, the energy-saving mode is read. corresponding configuration parameters, and determine the set temperature, power value and total running time of the air conditioner corresponding to the energy-saving mode according to the configuration parameters.

S30. Determine a frequency range and a frequency modulation speed corresponding to the air conditioner according to the environmental parameters and the power value.

Specifically, the frequency interval is a frequency range within which the operating frequency of the air conditioner can be located under the constraints of the environmental parameters and the power value. The frequency modulation speed is the speed at which the air conditioner operates and adjusts within the frequency range. In this embodiment, the frequency interval is determined according to the environmental parameters, and the frequency modulation speed is determined according to the environmental parameters and the power value. Correspondingly, the determining the frequency range and frequency modulation speed corresponding to the air conditioner according to the environmental parameters and the power value specifically includes:

S31. Calculate the temperature difference between the indoor temperature and the set temperature of the air conditioner, and determine a frequency interval corresponding to the air conditioner according to the temperature difference and the outdoor temperature;

S32. Determine a frequency modulation speed corresponding to the air conditioner according to the temperature difference and the power value.

Specifically, the temperature difference is the temperature difference between the indoor temperature and the set temperature, for example, the indoor temperature is 26°C, the set temperature of the air conditioner is 25°C, the temperature difference = indoor temperature - set temperature of the air conditioner = 26°C - 25°C = 1°C. In this embodiment, the determining the frequency interval corresponding to the air conditioner according to the temperature difference and the outdoor temperature may use a frequency fuzzy self-optimization control method to determine the frequency interval. Wherein, the specific process of the frequency fuzzy self-optimization control method may be as follows: First, the outdoor temperature and the temperature difference are processed according to the preset outdoor temperature interval set and temperature difference interval set, so as to determine the outdoor temperature interval corresponding to the outdoor temperature And the temperature difference interval corresponding to the temperature difference, the processing can be fuzzification; secondly, after determining the outdoor temperature interval and the temperature difference interval, determine the outdoor temperature interval according to the preset outdoor temperature interval and the corresponding relationship between the temperature difference interval and the frequency interval. Frequency range of temperature and temperature difference pairs.

For example: the preset outdoor temperature interval set and temperature difference interval set can be shown in Table 1, and the corresponding relationship between the preset outdoor temperature intervals, temperature difference intervals and frequency intervals can be shown in Table 2; assuming According to Table 1, it is determined that the outdoor temperature interval corresponding to the outdoor ambient temperature is temperature interval 3, and the temperature difference interval corresponding to the temperature difference is temperature interval 3, then the temperature interval 3 and the temperature difference interval 3 can be determined according to Table 2, and the frequency interval can be determined as the medium and high frequency interval MH.

Table 2 Correspondence between outdoor temperature range, temperature difference range and frequency range

Wherein, the symbols in Table 2 are shown in Table 4 below.

Further, in an implementation manner of this embodiment, the determining the frequency modulation speed corresponding to the air conditioner according to the temperature difference and the power value is determining the frequency modulation speed according to the temperature difference and the maximum power of the air conditioner. Correspondingly, the determining the frequency modulation speed corresponding to the air conditioner according to the temperature difference and the power value specifically includes:

S321. Determine a maximum frequency corresponding to the air conditioner according to the power value;

S322. Determine a frequency modulation speed corresponding to the air conditioner according to the temperature difference and the maximum frequency.

Specifically, the maximum power is the maximum power that the air conditioner is allowed to output in the energy-saving mode, and the maximum power is determined according to the power consumption value of the air conditioner in the energy-saving mode and the total running time of the air conditioner in the energy-saving mode, wherein the maximum Power = power value / total running time. In practical applications, due to the change of the operating frequency of the air conditioner, the power consumption of the air conditioner is different in each time period, which makes the maximum power of the air conditioner will change with the operation of the air conditioner when the total power value remains unchanged. Variety. Therefore, when acquiring the maximum power corresponding to the energy-saving mode, it can be calculated and updated in a periodic acquisition manner, so that in a preferred embodiment, as shown in FIG. The maximum frequency of , including:

L21. Periodically acquire the power consumption of the air conditioner in the energy-saving mode;

L22. Calculate the rated power of the air conditioner according to the power value and the power consumption, and set the rated power as the maximum power corresponding to the energy-saving mode.

Specifically, the periodic period is preset, for example, the period is 1 minute. The power consumption refers to the power consumption consumed by the air conditioner during the first running time in the energy-saving mode, and the remaining power value that can be consumed in the remaining second running time of the energy-saving mode can be calculated according to the power consumption. After the remaining power value is calculated, the rated power of the air conditioner at the time of acquisition is calculated according to the remaining power value, and then the rated power is set as the maximum power corresponding to the energy-saving mode. In this way, when calculating the rated power after the first running time of the air conditioner, even if the air conditioner runs at the maximum power during the second running time from the first running time to the total running time, the total power consumed by the air conditioner in the energy-saving mode can also be It is equal to the power value set in the energy-saving mode to meet the user's power demand.

Further, in an implementation of this embodiment, the calculating the rated power of the air conditioner according to the power value and the power consumption, and setting the rated power as the maximum power corresponding to the energy-saving mode may include the following step:

L211. Obtain the total running time corresponding to the energy-saving mode, and the first running time corresponding to the power consumption;

L212. Calculate the remaining second running time of the energy-saving mode according to the total running time and the first running time, and calculate the remaining power value according to the power value and the power consumption;

L213. Calculate the rated power of the air conditioner according to the remaining power value and the second running duration, and set the rated power as the maximum power corresponding to the energy-saving mode.

Specifically, the rated power is the maximum power that the air conditioner can output at the moment of acquisition, and the calculation formula of the rated power P _max (t) can be:

p _max (t) = (Q _max -Q _t )/(Tt)

Wherein, the Q _max represents the power consumption value of the air conditioner in the energy-saving mode, Q _t represents the power consumption of the air conditioner in the energy-saving mode for a total running time of t, T is the total running time corresponding to the energy-saving mode, and t is the air-conditioning in the energy-saving mode The first runtime of .

Further, in an implementation manner of this embodiment, the determining the frequency modulation speed corresponding to the air conditioner according to the temperature difference and the maximum frequency may adopt a frequency fuzzy self-optimization control method to determine the frequency modulation speed. The specific process of the frequency fuzzy self-optimization control method may be: process the temperature difference and the maximum power according to the preset temperature difference interval set and the maximum power interval set, so as to determine the second temperature difference interval and the maximum power corresponding to the temperature difference. The maximum power interval corresponding to the power, wherein the processing is preferably fuzzification; then determine the temperature difference and the frequency modulation speed corresponding to the maximum power according to the preset temperature difference interval and the corresponding relationship between the maximum power interval and the frequency modulation speed.

For example: the preset temperature difference interval set and the maximum power interval set are shown in Table 1, and the corresponding relationship between the preset temperature difference intervals, the maximum power interval and the frequency modulation speed is shown in Table 3, assuming that according to the table 1 Determine that the temperature difference interval corresponding to the temperature difference is the temperature difference interval 3, and the power interval corresponding to the maximum power is the power interval 6, then according to Table 3, it can be determined that the temperature difference interval 3 and the power interval 6 can be adjusted at a slow down D speed.

Table 3 Correspondence between temperature difference range, maximum power range and frequency modulation speed

Wherein, each symbol in said Table 3 is as shown in Table 4.

Further, after the frequency interval corresponding to the air conditioner is obtained, the optimal frequency corresponding to the air conditioner at the current moment is determined according to the frequency interval, which is recorded as the operating frequency of the air conditioner. When determining the operating frequency of the air conditioner according to the frequency range, it is first necessary to obtain the actual operating frequency of the air conditioner at the current moment, and determine the operating frequency of the air conditioner according to the actual operating frequency. Wherein, the determining the operating frequency of the air conditioner according to the actual operating frequency may be: when the actual operating frequency of the air conditioner is obtained, comparing the actual frequency with the upper limit value and the lower limit value of the frequency interval, if the If the actual frequency value is greater than the upper limit value, then set the upper limit value as the operating frequency of the air conditioner; if the actual frequency is less than the lower limit value, then set the lower limit value as the operating frequency of the air conditioner; if the If the actual frequency is less than or equal to the upper limit and greater than or equal to the lower limit, then the actual operating frequency is set as the operating frequency of the air conditioner. On the one hand, the jump range of the operating frequency can also be avoided through the frequency range, which avoids the instantaneous change of the cooling capacity/heating capacity of the air conditioner, and improves user comfort. For example, in one embodiment, the frequency interval corresponding to the outdoor temperature and the temperature difference is 30-40Hz, if the actual operating frequency of the air conditioner is 50Hz, then the operating frequency of the air conditioner is set to 40Hz; if the actual frequency of the air conditioner is 20Hz , set the operating frequency of the air conditioner to 30Hz; if the actual frequency of the air conditioner is 35Hz, set the operating frequency of the air conditioner to 35Hz.

S40. Determine the operating frequency of the air conditioner according to the frequency interval, and adjust the operating frequency of the air conditioner within the frequency interval according to the frequency modulation speed.

Specifically, after acquiring the frequency interval, the operating frequency of the air conditioner, and the frequency modulation speed, the operating frequency is adjusted according to the frequency modulation speed within the frequency interval, and if the frequency modulation speed is increasing, the frequency is increased within the frequency interval. Operating frequency, and after the operating frequency rises to the upper limit, keep the operating frequency at the upper limit; if the frequency modulation speed is decreasing, then reduce the operating frequency in the frequency range, and until the operating frequency drops to the lower limit value, keep the operating frequency at the lower limit. For example, if the frequency range is 30-40 Hz, the frequency modulation speed is slow down D, and the operating frequency is 32 Hz, then reduce the operating frequency, and when the operating frequency is reduced to 30 Hz, keep the operating frequency at 30 Hz. For another example, the frequency range is 30-40Hz, the frequency modulation speed is slow rise U, and the operating frequency is 38Hz, then increase the operating frequency, and when the operating frequency is reduced to 40Hz, keep the operating frequency at 40Hz.

Further, in one embodiment, the method further includes calculating the operating frequency of the air conditioner according to the maximum power when the operating state of the air conditioner in the energy-saving mode does not meet the preset condition, and controlling the air conditioner to follow the Run frequency run.

Specifically, the operation state of the air conditioner in the energy-saving mode does not meet the preset conditions, obtain the maximum power of the air conditioner, set the maximum power as the operation power of the air conditioner, calculate the operation frequency corresponding to the operation power, and control the The air conditioner operates according to the operating frequency. The maximum power is the maximum power calculated in step S20.

Further, in one embodiment, in order to facilitate users to understand the power consumption of the air conditioner, after the air conditioner runs for a predetermined period of time, it can obtain the power consumption consumed in the predetermined period of time, and send the power consumption to the cloud, and through the cloud The power consumption is sent to the external device of the APP used to control the air conditioner, so that the user can obtain the power consumption through the APP on the external device, so that the user can know the power consumption of the air conditioner at any time. The predetermined time period may be set by the user, or may be the default setting of the air conditioner, for example, the predetermined time period is from 6:00 pm to 6:00 am the next morning.

Further, in an implementation of this embodiment, as shown in FIG. 3, the method further includes:

N30. Adjust the opening and closing of the electronic expansion valve of the compressor according to the opening and closing speed until the exhaust gas temperature difference satisfies a set condition.

Specifically, the target discharge temperature of the electronic expansion valve of the compressor is determined according to the temperature value of the evaporator coil of the air conditioner internal unit and the condenser coil temperature value of the external unit of the air conditioner, and the calculation formula of the target discharge temperature can be:

Among them, T _{inner tube} is the temperature value of the evaporator coil of the air conditioner internal unit, T _{frequency weighted} is the weighted temperature value of the operating frequency, T _{outer tube} is the temperature value of the condenser coil of the air conditioner external unit, T _{condensing temperature compensation} is the condenser temperature of the air conditioner external unit Compensation temperature value, A ₁ , A ₂ and A ₃ are weighting parameters.
