[0031] Please refer to Figure 1 , a method for controlling an air conditioner provided by an embodiment of the present application specifically includes:

[0032] S110: In response to an operation instruction of the air conditioner, obtain first temperature information; the first temperature information includes the outdoor ambient temperature, the first indoor intake temperature, and the set temperature;

[0033] The operation instruction is used to start the air conditioner, and the air conditioner runs after receiving the operation instruction. The operation instruction can be an instruction input by the user through an external input device or on the control panel of the air conditioner. The external input device can be a device (such as a remote control, a mobile phone, or other terminals) that has established a control relationship with the air conditioner in advance.

[0034] The outdoor ambient temperature can be detected by a temperature detection device arranged outdoors or on the outdoor side of the air conditioner.

[0035] The first indoor intake temperature can be detected by a temperature detection device arranged at the air return opening on the indoor side of the air conditioner. Among them, the air return opening of the air conditioner is used to suck indoor air into the air conditioner.

[0036] The set temperature is the operation target temperature of the air conditioner. The set temperature can be the temperature set by the user according to needs, or the set temperature can also be the optimal operation temperature calculated by the air conditioner through a preset algorithm combined with the ambient temperature.

[0037] S120: Based on the preset initial frequency mapping information, determine the outdoor environmental temperature range corresponding to the outdoor environmental temperature, and obtain the initial frequency value corresponding to the outdoor environmental temperature range; wherein, the initial frequency mapping information includes multiple outdoor environmental temperature ranges and multiple difference ranges, one difference range corresponds to one initial frequency value, and one outdoor environmental temperature range corresponds to one frequency compensation value; the higher the outdoor environmental temperature range is in the temperature domain, the larger the corresponding initial frequency value is; the higher the difference range is in the temperature domain, the larger the corresponding frequency compensation value is.

[0038] The initial frequency mapping information is used to determine the target initial frequency corresponding to the first temperature information. Among them, for different differences between the indoor intake temperature and the set temperature and / or the outdoor environmental temperature, the corresponding initial frequencies are different.

[0039] The number, interval distribution, initial frequency value, and magnitude of the frequency compensation value of the outdoor environmental temperature range and the difference range in the initial frequency mapping information can be determined according to the optimal values of the experimental data through multiple experiments on the air conditioner, so that when the air conditioner operates according to the target initial frequency, it can meet the user's cooling demand and maintain stable operation at the same time.

[0040] By determining the initial frequency value according to the outdoor environmental temperature range where the outdoor environmental temperature is located and using the initial frequency value to determine the approximate range of the target initial frequency, it is possible to prevent the compressor from frequently increasing and decreasing the frequency in a high-temperature environment, which is beneficial to the stable operation of the system.

[0041] S130: Based on the preset initial frequency mapping information, determine the difference range corresponding to the difference between the first indoor intake temperature and the set temperature, and obtain the frequency compensation value corresponding to the difference range.

[0042] The frequency compensation value can be a specific value, percentage, or compensation coefficient.

[0043] By determining the frequency compensation value according to the difference range where the difference between the first indoor intake temperature and the set temperature is located and using the frequency compensation value to achieve precise adjustment of the target initial frequency, the frequency compensation value combines the indoor intake temperature and the set temperature to adjust the initial operating frequency of the compressor, making it more in line with the user's needs, and can improve the user's experience.

[0044] S140: Determine the target initial frequency according to the initial frequency value and the frequency compensation value, and control the compressor to operate at the target initial frequency.

[0045] The target initial frequency is obtained based on the frequency initial value and the frequency compensation value. The target initial frequency can be the sum of the frequency initial value and the frequency compensation value. Alternatively, when the frequency compensation value is a percentage or a compensation coefficient, the target initial frequency can also be the product of the frequency initial value and the frequency compensation value.

[0046] In an embodiment of the present application, by responding to the operation instruction of the air conditioner, the outdoor ambient temperature, the first indoor suction temperature, and the set temperature are obtained. The frequency initial value is determined according to the outdoor ambient temperature range corresponding to the outdoor ambient temperature, and then the frequency compensation value is determined according to the difference range corresponding to the difference between the indoor suction temperature and the set temperature. The target initial frequency is determined based on the frequency initial value and the frequency compensation value, and the accurate control of the operation frequency of the air conditioner is achieved by combining the outdoor ambient temperature, the indoor suction temperature, and the set temperature. The present application can enable the air conditioner to operate at a stable temperature and efficiently refrigerate in a high-temperature environment, improving the operation reliability, refrigeration effect, and user experience of the air conditioner.

[0047] In one embodiment, the initial frequency mapping information includes a first outdoor ambient temperature range, a second outdoor ambient temperature range, a third outdoor ambient temperature range, a first difference range, a second difference range, a third difference range, a fourth difference range, a first frequency initial value, a second frequency initial value, a third frequency initial value, a first frequency compensation value, a second frequency compensation value, and a third frequency compensation value; the first frequency initial value, the second frequency initial value, and the third frequency initial value respectively correspond to the first outdoor ambient temperature range, the second outdoor ambient temperature range, and the third outdoor ambient temperature range, and the first frequency compensation value, the second frequency compensation value, and the third frequency compensation value respectively correspond to the first difference range, the second difference range, and the third difference range.

[0048] Determining the target initial frequency corresponding to the first temperature information according to the difference between the first indoor suction temperature and the set temperature and the outdoor ambient temperature includes:

[0049] If the outdoor ambient temperature is within the first outdoor ambient temperature range, obtain the first frequency initial value corresponding to the first outdoor ambient temperature range, and if the difference between the first indoor suction temperature and the set temperature is within the first difference range, obtain the first frequency compensation value corresponding to the first difference range, and determine the first target initial frequency according to the first frequency initial value and the first frequency compensation value;

[0050] If the outdoor ambient temperature is within the first outdoor ambient temperature range, obtain the first frequency initial value corresponding to the first outdoor ambient temperature range, and if the difference between the first indoor suction temperature and the set temperature is within the second difference range, obtain the second frequency compensation value corresponding to the second difference range, and determine the second target initial frequency according to the first frequency initial value and the second frequency compensation value;

[0051] If the outdoor environmental temperature is within the first outdoor environmental temperature range, obtain a first frequency initial value corresponding to the first outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the third difference range, obtain a third frequency compensation value corresponding to the third difference range, and determine a third target initial frequency according to the first frequency initial value and the third frequency compensation value;

[0052] If the outdoor environmental temperature is within the first outdoor environmental temperature range, obtain a first frequency initial value corresponding to the first outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the fourth difference range, determine a fourth target initial frequency according to the first frequency initial value;

[0053] If the outdoor environmental temperature is within the second outdoor environmental temperature range, obtain a second frequency initial value corresponding to the second outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the first difference range, obtain a first frequency compensation value corresponding to the first difference range, and determine a fifth target initial frequency according to the second frequency initial value and the first frequency compensation value;

[0054] If the outdoor environmental temperature is within the second outdoor environmental temperature range, obtain a second frequency initial value corresponding to the second outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the second difference range, obtain a second frequency compensation value corresponding to the second difference range, and determine a sixth target initial frequency according to the second frequency initial value and the second frequency compensation value;

[0055] If the outdoor environmental temperature is within the second outdoor environmental temperature range, obtain a second frequency initial value corresponding to the second outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the third difference range, obtain a third frequency compensation value corresponding to the third difference range, and determine a seventh target initial frequency according to the second frequency initial value and the third frequency compensation value;

[0056] If the outdoor environmental temperature is within the second outdoor environmental temperature range, obtain a second frequency initial value corresponding to the second outdoor environmental temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the fourth difference range, determine an eighth target initial frequency according to the second frequency initial value;

[0057] If the outdoor ambient temperature is within the third outdoor ambient temperature range, obtain the third initial frequency value corresponding to the third outdoor ambient temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the first difference range, obtain the first frequency compensation value corresponding to the first difference range, and determine the ninth target initial frequency according to the third initial frequency value and the first frequency compensation value;

[0058] If the outdoor ambient temperature is within the third outdoor ambient temperature range, obtain the third initial frequency value corresponding to the third outdoor ambient temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the second difference range, obtain the second frequency compensation value corresponding to the second difference range, and determine the tenth target initial frequency according to the third initial frequency value and the second frequency compensation value;

[0059] If the outdoor ambient temperature is within the third outdoor ambient temperature range, obtain the third initial frequency value corresponding to the third outdoor ambient temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the third difference range, obtain the third frequency compensation value corresponding to the third difference range, and determine the eleventh target initial frequency according to the third initial frequency value and the third frequency compensation value;

[0060] If the outdoor ambient temperature is within the third outdoor ambient temperature range, obtain the third initial frequency value corresponding to the third outdoor ambient temperature range, and if the difference between the first indoor intake temperature and the set temperature is within the fourth difference range, determine the twelfth target initial frequency according to the third initial frequency value;

[0061] Among them, the first outdoor ambient temperature range, the second outdoor ambient temperature range, and the third outdoor ambient temperature range are three temperature ranges in the temperature field, and the three temperature ranges are distributed from high to low according to the temperature: the first outdoor ambient temperature range > the second outdoor ambient temperature range > the third outdoor ambient temperature range. The first initial frequency value > the second initial frequency value > the third initial frequency value.

[0062] Specifically, assume that the outdoor ambient temperature is Tout. When Tout > Tout3, the outdoor ambient temperature is within the first outdoor ambient temperature range, and the corresponding first initial frequency value is F3. When Tout2 ≤ Tout < Tout3, the outdoor ambient temperature is within the second outdoor ambient temperature range, and the corresponding second initial frequency value is F2. When Tout1 ≤ Tout < Tout2, the outdoor ambient temperature is within the third outdoor ambient temperature range, and the corresponding third initial frequency value is F1. Among them, Tout1, Tout2, and Tout3 are the threshold values of the outdoor ambient temperature range, Tout3 > Tout2 > Tout1, and F3 > F2 > F1.

[0063] The first difference interval, the second difference interval, the third difference interval, and the fourth difference interval are three intervals in the temperature field. The four difference intervals are distributed from high to low according to the difference magnitude: the first difference interval > the second difference interval > the third difference interval > the fourth difference interval. The first frequency compensation value > the second frequency compensation value > the third frequency compensation value > 0.

[0064] Specifically, assume that the difference between the first indoor intake temperature and the set temperature is A. When A > Tin3, the difference between the first indoor intake temperature and the set temperature is in the first difference interval, and the corresponding first frequency compensation value is △F3. When Tin2 < A ≤ Tin3, the difference between the first indoor intake temperature and the set temperature is in the second difference interval, and the corresponding second frequency compensation value is △F2; when Tin1 < A ≤ Tin2, the difference between the first indoor intake temperature and the set temperature is in the third difference interval, and the corresponding third frequency compensation value is △F1; when A < Tin1, the difference between the first indoor intake temperature and the set temperature is in the fourth difference interval, and the corresponding frequency compensation value can be 0. Tin1, Tin2, and Tin3 are the difference interval thresholds respectively, Tin3 > Tin2 > Tin1, and △F3 > △F2 > △F1 > 0.

[0065] In the embodiment of the present application, the target initial frequency can be the sum of the frequency initial value and the frequency compensation value.

[0066] In the embodiment of the present application, by using the outdoor environment temperature interval where the outdoor environment temperature is located to determine the frequency initial value corresponding to the outdoor environment temperature, thereby determining the approximate range of the target initial frequency according to the frequency initial value, the compressor is prevented from frequently increasing and decreasing its frequency, which affects the operation stability of the air conditioner; then, according to the difference interval where the difference between the first indoor intake temperature and the set temperature is located, the target initial frequency is further determined, realizing the precise determination of the target initial frequency and improving the refrigeration effect of the air conditioner and the user experience.

[0067] In one embodiment, during the operation of the air conditioner, the operating frequency of the compressor can also be adjusted according to the exhaust temperature and the exhaust superheat. Specifically, as Figure 2 shown, the method may further include:

[0068] S150: Obtain the second temperature information and the operating frequency of the compressor; the second temperature information includes the exhaust temperature and the exhaust superheat;

[0069] The exhaust temperature can be detected by a temperature detection device provided at the exhaust end of the compressor.

[0070] The superheat degree of the exhaust can be obtained based on the difference between the exhaust temperature or the temperature at the inlet of the air conditioner condenser and the saturation temperature corresponding to the actual condensation pressure. The temperature at the inlet of the air conditioner condenser can be detected by a temperature detection device provided at the inlet of the condenser.

[0071] The superheat degree of the exhaust can reflect the heat dissipation effect of the condenser. In a high-temperature environment, when the installation space of the outdoor unit is narrow and the environment is relatively enclosed, the heat dissipation effect of the outdoor unit is poor, and the condenser cannot dissipate heat effectively, resulting in an increase in the condensation temperature. The increase in the condensation temperature will cause the pressure of the refrigerant to increase, affecting the efficiency of the refrigeration cycle; the increase in the condensation pressure will cause the evaporation temperature to increase, and the heat exchange efficiency of the evaporator to decrease. The increase in the evaporation temperature will cause the refrigeration effect of the indoor unit to deteriorate, and the indoor temperature cannot be reduced to the expected level, affecting the refrigeration effect of the air conditioner. Therefore, by combining the exhaust temperature and the superheat degree of the exhaust to adjust the operating frequency of the air conditioner, the operating efficiency of the air conditioner can be improved, energy consumption can be reduced, the service life can be extended, and the refrigeration effect and operating reliability of the air conditioner can be improved.

[0072] S160: Determine the magnitude relationship between the exhaust temperature and the target exhaust temperature and the magnitude relationship between the superheat degree of the exhaust and the target superheat degree of the exhaust;

[0073] The target exhaust temperature can be an ideal exhaust temperature preset by the user, and the target exhaust temperature can be determined based on the operating data of the compressor.

[0074] The target superheat degree of the exhaust can be an ideal superheat degree of the exhaust preset by the user, and the target superheat degree of the exhaust can be determined based on the operating data of the compressor.

[0075] The magnitude relationship between the exhaust temperature and the target exhaust temperature can include: the exhaust temperature is greater than the target exhaust temperature, the exhaust temperature is less than the target exhaust temperature, and the exhaust temperature is equal to the target exhaust temperature.

[0076] The magnitude relationship between the superheat degree of the exhaust and the target superheat degree of the exhaust can include: the superheat degree of the exhaust is greater than the target superheat degree of the exhaust, the superheat degree of the exhaust is less than the target superheat degree of the exhaust, and the superheat degree of the exhaust is equal to the target superheat degree of the exhaust

[0077] S170: Based on the preset adjustment frequency mapping information, determine whether it is necessary to adjust the operating frequency of the compressor according to the magnitude relationship between the exhaust temperature and the target exhaust temperature and the magnitude relationship between the superheat degree of the exhaust and the target superheat degree of the exhaust.

[0078] The adjustment frequency mapping information is used to determine whether it is necessary to adjust the operating frequency of the compressor, and the adjustment frequency mapping information can include various compressor operating frequency adjustment methods corresponding to the magnitude relationship between the exhaust temperature and the target exhaust temperature and the magnitude relationship between the superheat degree of the exhaust and the target superheat degree of the exhaust.

[0079] The adjustment methods of the compressor operating frequency may include increasing the compressor operating frequency, decreasing the compressor operating frequency, and keeping the compressor operating frequency unchanged.

[0080] When first obtaining the compressor operating frequency, the obtained compressor operating frequency may be the target initial frequency. During the operation of the air conditioner, the above steps are repeatedly executed to achieve real-time adjustment of the compressor operating frequency, thereby improving the refrigeration effect of the air conditioner.

[0081] In the embodiments of the present application, the compressor operating frequency is adjusted according to the magnitude relationship between the exhaust temperature and the target exhaust temperature and the magnitude relationship between the exhaust superheat and the target exhaust superheat. By combining the exhaust temperature and the exhaust superheat to adjust the operating frequency of the air conditioner, the refrigeration effect of the air conditioner can be effectively improved.

[0082] As Figure 3 shown, in one embodiment, determining whether to adjust the compressor operating frequency according to the magnitude relationship between the exhaust temperature and the target exhaust temperature and the magnitude relationship between the exhaust superheat and the target exhaust superheat includes:

[0083] S171: If the exhaust temperature is less than the target exhaust temperature, determine whether to increase the compressor operating frequency according to the magnitude relationship between the exhaust superheat and the target exhaust superheat;

[0084] When the exhaust temperature is less than the target exhaust temperature, the magnitude relationship between the exhaust superheat and the target exhaust superheat is used to determine whether to increase the compressor operating frequency. When it is determined that there is no need to increase the compressor operating frequency, the compressor is made to operate at the current operating frequency.

[0085] In one embodiment, determining whether to increase the compressor operating frequency according to the magnitude relationship between the exhaust superheat and the target exhaust superheat includes:

[0086] If the exhaust superheat is less than or equal to the target exhaust superheat, keep the compressor operating frequency unchanged;

[0087] If the exhaust superheat is greater than the target exhaust superheat, increase the compressor operating frequency.

[0088] Increase the compressor operating frequency to the set first target operating frequency. Alternatively, the compressor operating frequency can also be gradually increased at a preset frequency increase rate to ensure the stable operation of the compressor.

[0089] S172: If the exhaust temperature is greater than or equal to the target exhaust temperature, determine whether to decrease the compressor operating frequency according to the magnitude relationship between the exhaust superheat and the target exhaust superheat.

[0090] When the exhaust gas temperature is greater than or equal to the target exhaust gas temperature, the magnitude relationship between the superheat degree of the exhaust gas and the target superheat degree of the exhaust gas is used to determine whether to reduce the operating frequency of the compressor. When it is determined that there is no need to reduce the operating frequency of the compressor, the compressor is made to operate at the current operating frequency.

[0091] In one embodiment, determining whether to reduce the operating frequency of the compressor according to the magnitude relationship between the superheat degree of the exhaust gas and the target superheat degree of the exhaust gas includes:

[0092] If the exhaust gas temperature is equal to the target exhaust gas temperature and the superheat degree of the exhaust gas is greater than or equal to the target superheat degree of the exhaust gas, keep the operating frequency of the compressor unchanged;

[0093] If the exhaust gas temperature is equal to the target exhaust gas temperature and the superheat degree of the exhaust gas is less than the target superheat degree of the exhaust gas, reduce the operating frequency of the compressor;

[0094] If the exhaust gas temperature is greater than the target exhaust gas temperature and the superheat degree of the exhaust gas is greater than the target superheat degree of the exhaust gas, keep the operating frequency of the compressor unchanged;

[0095] If the exhaust gas temperature is greater than the target exhaust gas temperature and the superheat degree of the exhaust gas is less than or equal to the target superheat degree of the exhaust gas, reduce the operating frequency of the compressor.

[0096] An excessively high exhaust gas temperature can cause problems such as overheating and damage of compressor components and decomposition of lubricating oil, affecting the service life and operating reliability of the compressor. An appropriate exhaust gas temperature can optimize the compression process and improve the operating efficiency.

[0097] There is a positive correlation between the operating frequency of the compressor and the exhaust gas temperature. Increasing the operating frequency of the compressor can increase the exhaust gas temperature, and reducing the operating frequency of the compressor can reduce the exhaust gas temperature. Adjust the operating frequency of the compressor according to the exhaust gas temperature and the target exhaust gas temperature to make the exhaust gas temperature closer to the target exhaust gas temperature.

[0098] Reduce the operating frequency of the compressor and reduce the operating frequency of the compressor to the set second target operating frequency. Alternatively, it is also possible to gradually reduce the operating frequency of the compressor according to a preset frequency reduction rate to ensure the stable operation of the compressor.

[0099] In the embodiment of the present application, when the exhaust gas temperature is less than the target exhaust gas temperature, it is determined whether to increase the operating frequency of the compressor according to the magnitude relationship between the superheat degree of the exhaust gas and the target superheat degree of the exhaust gas. When the exhaust gas temperature is greater than or equal to the target exhaust gas temperature, it is determined whether to reduce the operating frequency of the compressor according to the magnitude relationship between the superheat degree of the exhaust gas and the target superheat degree of the exhaust gas. Combine the exhaust gas temperature and the superheat degree of the exhaust gas to control the operating frequency of the compressor and improve the operating reliability of the compressor and the heat exchange effect of the condenser.

[0100] In an optional embodiment, the compressor of the air conditioner may be made to operate at a target initial frequency for a period of time before adjusting the operating frequency of the compressor, so as to improve the accuracy of adjusting the operating frequency of the compressor and the operating stability of the air conditioner.

[0101] Specifically, obtaining the second temperature information and the operating frequency of the compressor includes:

[0102] Obtaining a first duration for which the compressor operates at the target initial frequency;

[0103] When the first duration reaches a first preset operating duration, obtaining the second temperature information and the operating frequency of the compressor.

[0104] The first preset operating duration can be set according to user requirements.

[0105] In an embodiment, during the operation of the air conditioner, the rotational speed of the indoor fan can also be adjusted. The indoor fan is used to circulate the indoor air and perform heat exchange through the evaporator, and blow the processed air back into the room, thereby realizing the adjustment of the indoor temperature.

[0106] By increasing the rotational speed of the indoor fan, the air flow speed can be increased, making the heat exchange between the indoor air and the evaporator more sufficient and improving the refrigeration effect.

[0107] As Figure 4 shown, the method of the embodiment of the present application further includes:

[0108] S210: Obtaining the second indoor intake temperature and the current rotational speed of the indoor fan;

[0109] S220: Based on the preset rotational speed mapping information, determining a difference interval corresponding to the difference between the second indoor intake temperature and the set temperature, and determining a target rotational speed according to the target rotational speed adjustment value and the current rotational speed;

[0110] The rotational speed mapping information includes a plurality of target rotational speed adjustment values and target rotational speeds corresponding to the difference intervals.

[0111] The target rotational speed adjustment value is used to determine the rotational speed adjustment rate of the indoor fan, so as to avoid the rotational speed of the indoor fan being adjusted too fast and affecting the normal operation of the air conditioner. For different difference intervals, the target rotational speed adjustment values can be the same or different.

[0112] The target rotational speed can be a rotational speed obtained by adjusting on the basis of the current rotational speed. Specifically, the target rotational speed can be the current rotational speed plus the target rotational speed adjustment value. For example, if the current rotational speed is 10 rpm and the target rotational speed adjustment value is 20 rpm, the target rotational speed can be 30 rpm.

[0113] S230: Adjust the rotational speed of the indoor fan to the target rotational speed.

[0114] Optionally, the rotational speed of the indoor fan can be gradually adjusted to the target rotational speed according to a preset rotational speed adjustment rate, so as to avoid the too-fast adjustment of the rotational speed of the indoor fan and affect the normal operation of the air conditioner.

[0115] The rotational speed adjustment rate can be set according to the current rotational speed, the target rotational speed adjustment value or user requirements. In the embodiments of the present application, the rotational speed adjustment rate can be 20 rpm / 10 s.

[0116] The target rotational speed can be greater than or equal to the current rotational speed, so as to improve the refrigeration efficiency and refrigeration effect by increasing the rotational speed of the indoor fan. When the target rotational speed is equal to the current rotational speed, there is no need to adjust the rotational speed of the fan.

[0117] In the embodiments of the present application, by obtaining the target rotational speed adjustment value according to the difference between the second indoor suction temperature and the set temperature, determining the target rotational speed according to the target rotational speed adjustment value and the current rotational speed, and adjusting the current rotational speed of the indoor fan to the target rotational speed, the air flow speed is accelerated, so that the heat exchange between the indoor air and the evaporator is more sufficient, and the refrigeration effect is improved.

[0118] In one embodiment, obtaining the target rotational speed adjustment value corresponding to the difference interval and determining the target rotational speed according to the target rotational speed adjustment value and the current rotational speed includes:

[0119] If the difference between the second indoor suction temperature and the set temperature is in the first interval, obtain the first rotational speed adjustment value corresponding to the first interval, and determine the first target rotational speed according to the first rotational speed adjustment value and the current rotational speed;

[0120] If the difference between the second indoor suction temperature and the set temperature is in the second interval, obtain the second rotational speed adjustment value corresponding to the second interval, and determine the second target rotational speed according to the second rotational speed adjustment value and the current rotational speed;

[0121] If the difference between the second indoor suction temperature and the set temperature is in the third interval, obtain the third rotational speed adjustment value corresponding to the third interval, and determine the third target rotational speed according to the third rotational speed adjustment value and the current rotational speed;

[0122] If the difference between the second indoor suction temperature and the set temperature is in the fourth interval, keep the current rotational speed of the indoor fan unchanged;

[0123] Wherein, the first target rotational speed > the second target rotational speed > the third target rotational speed > the current rotational speed.

[0124] In the embodiments of the present application, the first rotational speed adjustment value may be 60 rpm, the second rotational speed adjustment value may be 40 rpm, and the third rotational speed adjustment value may be 20 rpm. The first target rotational speed is to increase by 60 rpm based on the current rotational speed, the second target rotational speed is to increase by 40 rpm based on the current rotational speed, and the third target rotational speed is to increase by 20 rpm based on the current rotational speed. At a rotational speed adjustment rate of 20 rpm / 10 s, gradually increase the rotational speed of the internal blower until the rotational speed of the internal blower is equal to the target rotational speed.

[0125] Assume that the difference between the second indoor intake temperature and the set temperature is A1. When A1 > Tin31, the difference between the second indoor intake temperature and the set temperature is in the first interval. When Tin21 < A1 < Tin31, the difference between the second indoor intake temperature and the set temperature is in the second interval; when Tin11 < A1 < Tin21, the difference between the second indoor intake temperature and the set temperature is in the third interval; when 0°C < A1 < Tin11, the difference between the second indoor intake temperature and the set temperature is in the fourth interval. Tin11, Tin21, and Tin31 are interval thresholds respectively.

[0126] In one embodiment, obtaining the second indoor intake temperature and the current rotational speed of the internal blower includes:

[0127] Obtaining the second duration for which the compressor operates at the target initial frequency;

[0128] When the second duration reaches the second preset operating duration, obtain the second indoor intake temperature and the current rotational speed of the internal blower.

[0129] The second preset operating duration can be set according to user requirements. The second preset operating duration may be the same as or different from the first preset operating duration.

[0130] In the embodiments of the present application, the second preset operating duration is the same as the first preset operating duration. By simultaneously adjusting the operating frequency of the compressor and the rotational speed of the internal blower, the refrigeration efficiency and refrigeration effect are improved. During the operation of the air conditioner, the above steps can be repeatedly executed to achieve real-time adjustment of the operating frequency of the compressor and the rotational speed of the internal blower.

[0131] By making the compressor of the air conditioner operate at the target initial frequency for a period of time and then adjusting the rotational speed of the internal blower, the operating stability of the air conditioner is improved.
