[0032] The acquisition, storage, use, and processing of data in the technical solution of this application comply with the relevant provisions of national laws and regulations.

[0033] Figure 1 is a flow chart of a method for controlling the air volume of an air conditioner according to an exemplary embodiment. Figure 1 As shown, the air volume control method of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0034] S101, for any one of the indoor unit and the outdoor unit, obtain target state information of any one of the units.

[0035] It should be noted that the air volume control method for the air conditioner in the embodiment of the present application is performed by the air conditioner. Optionally, the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, a ceiling air conditioner, a window air conditioner, a central air conditioner, etc. In the present application, the type of air conditioner is not too limited. The air volume control method for the air conditioner in the embodiment of the present application can be performed by the control device of the air conditioner itself.

[0036] The following is an explanation of the air volume control method of the air conditioner provided in the embodiment of the present application, with the air conditioner itself as the execution subject:

[0037] In some implementations, if any unit is an indoor unit, the target state information of the indoor unit includes indoor temperature, indoor humidity, and inner tube temperature of the evaporator; if any unit is an outdoor unit, the target state information of the outdoor unit includes outdoor temperature and outer tube temperature of the condenser.

[0038] In some implementations, one or more temperature sensors may be provided on the air conditioner to obtain the indoor temperature, outdoor temperature, inner tube temperature of the evaporator, and outer tube temperature of the condenser of the air conditioner, that is, the air conditioner detects the indoor temperature, outdoor temperature, inner tube temperature of the evaporator, and outer tube temperature of the condenser based on the temperature sensors installed on the air conditioner. Optionally, an evaporator tube temperature sensing package may be used to detect the inner tube temperature of the evaporator; optionally, a condenser tube temperature sensing package may be used to detect the outer tube temperature of the condenser.

[0039] In some implementations, one or more humidity sensors may be provided on the air conditioner to obtain the indoor humidity of the air conditioner, that is, the air conditioner detects the indoor humidity of the air conditioner based on the humidity sensor installed on the air conditioner. In this application, the temperature sensor and the humidity sensor are not limited.

[0040] S102: Determine the target air volume that needs to be compensated for any unit according to the target state information.

[0041] In the embodiment of the present application, the target air volume that any unit needs to compensate is determined by the operation mode of the air conditioner based on the target state information. That is, the indoor unit and the outdoor unit can determine the target air volume that the indoor unit and the outdoor unit need to compensate based on their corresponding target state information and the operation mode of the air conditioner. The operation mode of the air conditioner is divided into a cooling mode and a heating mode.

[0042] In some implementations, the air volume that needs to be increased can be fitted based on the dew point temperature, the amount of reduction in hot air density, and the indoor resistance when the indoor air circulation is increased, as the target air volume that any unit needs to compensate. The dew point temperature, the amount of reduction in air density, and the indoor resistance when the indoor air circulation is increased can be calculated through the target state information.

[0043] S103, determining a speed adjustment amount of a target fan in any unit according to the target air volume and the speed of the internal fan, and adjusting the speed of the target fan based on the adjustment amount.

[0044] In some implementations, the speed adjustment amount of the target fan in any unit can be determined according to the target air volume and the speed of the internal fan of any unit in different operating modes of the air conditioner. Optionally, the speed adjustment amount can be added to the current speed of the target fan to adjust the speed of the target fan. Optionally, the windshield size of the target fan to be adjusted can be determined according to the speed adjustment amount of the target fan, and the speed of the target fan can be adjusted by adjusting the windshield of the target fan.

[0045] Optionally, when the target fan is an indoor unit, the speed adjustment amount of the indoor unit in different operating modes is calculated according to the target air volume that the indoor unit needs to compensate for and the speed of the indoor fan in different operating modes. Optionally, when the target fan is an outdoor unit, the speed adjustment amount of the outdoor unit in different operating modes is calculated according to the target air volume that the outdoor unit needs to compensate for and the speed of the indoor fan in different operating modes.

[0046] In the air volume control method of the air conditioner provided in the embodiment of the present application, the target state information corresponding to the indoor unit and the outdoor unit is determined, and the target air volume that needs to be compensated for any unit is determined according to the target state information. Furthermore, according to the target air volume and the current speed of the indoor fan, the speed adjustment amount of the indoor unit and the outdoor unit can be determined, and then the speed of the indoor unit and the outdoor unit can be adjusted. By increasing the speed of the indoor unit, the air volume control is achieved to enhance the air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, and reducing energy consumption, saving electricity costs.

[0047] Figure 2 is a flow chart of a method for controlling the air volume of an air conditioner according to an exemplary embodiment. Figure 2 As shown, the air volume control method of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0048] S201, for any one of the indoor unit and the outdoor unit, obtain target state information of any one of the units.

[0049] In the embodiment of the present application, the implementation method of step S201 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0050] S202, determining the current operation mode of the air conditioner.

[0051] In the embodiment of the present application, the operation mode of the air conditioner includes a cooling mode and a heating mode. Optionally, the air conditioner can determine the current operation mode of the air conditioner according to the selection of the user based on the remote control or the control panel. Optionally, the air conditioner can automatically determine the current operation mode according to the temperature difference between the current indoor temperature and the set temperature.

[0052] S203, based on the operation mode and target state information, a target air volume that needs to be compensated for any unit under the same noise condition is calculated.

[0053] In some implementations, it is determined that the current operating mode of the air conditioner is a cooling mode. Optionally, based on the target state information of the indoor unit, that is, the indoor temperature, the indoor humidity, and the inner tube temperature of the evaporator, the dew point temperature of the air conditioner is calculated, and the air volume lost during indoor air circulation under the same noise is fitted according to the dew point temperature, which is used as the target air volume that the indoor unit needs to compensate. Optionally, based on the target state information of the outdoor unit, that is, the outdoor temperature and the outer tube temperature of the condenser, the reduction in hot air density is calculated, and then the air volume that needs to be increased under the same noise is fitted, which is used as the target air volume that the outdoor unit needs to compensate.

[0054] In some implementations, it is determined that the current operating mode of the air conditioner is a heating mode. Optionally, based on the target state information of the indoor unit, that is, the indoor temperature, the indoor humidity, and the inner tube temperature of the evaporator, the hot air density reduction is calculated, and then the air volume that needs to be increased under the same noise is fitted as the target air volume that the indoor unit needs to compensate. Optionally, based on the target state information of the outdoor unit, that is, the outdoor temperature and the outer tube temperature of the condenser, the indoor resistance when the indoor air circulation is increased is calculated, and then the air volume lost when the indoor air circulates under the same noise is fitted as the target air volume that the outdoor unit needs to compensate.

[0055] It is understandable that the target air volume that needs to be compensated under simulated equal noise refers to the air volume that needs to be increased by the air conditioner under certain noise limit conditions. By calculating the target air volume that needs to be compensated under simulated equal noise, the noise level can be minimized to provide a more comfortable indoor environment while meeting the air circulation and quality requirements. This can reduce unnecessary wind energy consumption and improve energy efficiency.

[0056] S204, determining a speed adjustment amount of a target fan in any unit according to the target air volume and the speed of the internal fan, and adjusting the speed of the target fan based on the adjustment amount.

[0057] In the embodiment of the present application, the implementation method of step S204 can be implemented by any method in the embodiments of the present application, which is not limited here and will not be repeated.

[0058] In the air volume control method of the air conditioner provided in the embodiment of the present application, the target state information corresponding to the indoor unit and the outdoor unit, as well as the current operation mode of the air conditioner are determined, and the target air volume that needs to be compensated for any unit is determined according to the operation mode and the target state information. Furthermore, according to the target air volume and the current speed of the indoor fan, the speed adjustment amount of the indoor unit and the outdoor unit can be determined, and then the speed of the indoor unit and the outdoor unit can be adjusted. By increasing the speed of the indoor unit, air volume control is achieved to enhance air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, and reducing energy consumption, saving electricity costs.

[0059] Figure 3 is a flow chart of a method for controlling the air volume of an air conditioner according to an exemplary embodiment. Figure 3 As shown, the air volume control method of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0060] S301, for an indoor unit, obtaining target state information of the indoor unit.

[0061] In some implementations, the indoor environment parameters of the indoor unit and the inner tube temperature of the evaporator in the indoor unit can be obtained as the target state information of the indoor unit through one or more temperature sensors and humidity sensors of the air conditioner itself. The indoor environment parameters include at least one of the following parameters: indoor temperature and indoor humidity.

[0062] S302: If the air conditioner is in cooling mode, the dew point temperature of the air conditioner is determined based on indoor environmental parameters and the internal pipe temperature.

[0063] In some implementations, it is determined that the current operating mode of the air conditioner is the cooling mode, and the dew point temperature of the air conditioner can be calculated based on at least one of the indoor environmental parameters indoor temperature and indoor humidity, and the evaporator inner tube temperature.

[0064] It can be understood that the dew point temperature refers to the temperature at which water vapor in the air begins to condense into water when the air is cooled to a certain temperature. The air conditioner lowers the indoor temperature by cooling the indoor air, which reduces the water vapor content in the air in the process. When the temperature of the indoor air drops below the dew point temperature, water vapor will begin to condense into water, indicating that the indoor humidity has reached saturation.

[0065] S303, a first air volume lost during indoor air circulation under the same noise is estimated according to the dew point temperature as a target air volume that the indoor unit needs to compensate.

[0066] It is understandable that the dew point temperature of the air conditioner affects the indoor air circulation. Since the air contains more moisture, it affects the circulation of air in the indoor unit and reduces the air volume of the indoor unit. Therefore, the first air volume lost during the indoor air circulation is used as the target air volume that the indoor unit needs to compensate.

[0067] In some implementations, the first air volume lost during indoor air circulation under the same noise can be estimated based on the dew point temperature of the air conditioner and the inner tube temperature of the evaporator, and used as the target air volume that the indoor unit needs to compensate. The formula for calculating the first air volume is as follows:

[0068] Q d1 =K1(a1T e -b1T d ) (1)

[0069] Among them, Q d1 is the first air volume, T d is the dew point temperature, T e is the temperature of the inner tube of the evaporator, K1, a1, b1 are calculation coefficients, and 10<K1≤100, 0<b1≤a1≤10.

[0070] S304: Determine the speed adjustment amount of the indoor unit according to the target air volume and the speed of the indoor fan, and adjust the speed of the indoor unit based on the adjustment amount.

[0071] In some implementations, the speed adjustment amount of the indoor unit in the cooling mode can be calculated by the target air volume that the indoor unit needs to compensate and the current speed of the indoor fan. The formula for calculating the speed adjustment amount of the indoor unit is as follows:

[0072] η1=K2Q d1 / r1 2 (2)

[0073] Among them, η1 is the speed adjustment amount of the indoor unit in the cooling mode, r1 is the current speed of the indoor fan in the cooling mode, K2 is the calculation coefficient, and 1<K2≤30.

[0074] Furthermore, according to the speed adjustment amount of the indoor unit, the size of the windshield of the indoor unit to be adjusted is determined, and the speed of the indoor unit is adjusted by adjusting the windshield of the indoor unit. By increasing the speed of the indoor unit through control execution, the air conditioning refrigeration capacity is improved, the comfort effect is improved, and energy consumption is reduced.

[0075] For example, when the air conditioner is in cooling mode, the windshield size F of the indoor unit of the air conditioner is detected. d , Sweep air position S t(up and down, left and right), among which, the wind speed size is divided into low speed, medium speed, high speed, ultra-high speed, etc. If the current wind speed size of the indoor unit is medium speed, the speed adjustment amount of the indoor unit is used to determine that the wind speed size of the indoor unit needs to be adjusted to high speed, and then the speed of the indoor unit is adjusted, and the sweeping position remains unchanged.

[0076] S305: If the air conditioner is in the heating mode, a first hot air density reduction amount during indoor air circulation is determined based on the indoor environmental parameters and the inner pipe temperature.

[0077] In some implementations, it is determined that the current operation mode of the air conditioner is the heating mode, and based on the indoor environmental parameters of the indoor temperature, the indoor humidity, and the temperature of the evaporator inner tube, the first hot air density reduction during indoor air circulation can be calculated. The formula for calculating the first hot air density reduction is as follows:

[0078] Δρ1=K3(c1T e -d1T n ) (3)

[0079] Where Δρ1 is the first hot air density reduction, T n is the indoor temperature, T e is the temperature of the inner tube of the evaporator, K3, c1, d1 are calculation coefficients, and 10<K3≤100, 0<c1≤d1≤10.

[0080] S306, according to the first hot air density reduction, a second air volume that needs to be increased under the same noise is calculated as the target air volume that the indoor unit needs to compensate.

[0081] It is understandable that in heating mode, the air conditioner will draw in air from the outside and heat it, and then send the heated air back to the room through the indoor circulation. Since the distance between air molecules in the room increases due to heating, the density of indoor air will decrease. The indoor unit needs to move more air molecules to achieve the same air flow. Therefore, the indoor unit needs to provide a larger air volume to maintain the indoor air circulation and heating effect.

[0082] In some implementations, the second air volume that needs to be increased under the same noise can be calculated based on the first hot air density reduction, and used as the target air volume that the indoor unit needs to compensate in the heating mode. The formula for calculating the second air volume is as follows:

[0083] Q d2 =K4Δρ1 (4)

[0084] Among them, Q d2 is the second air volume, K4 is the calculation coefficient, and 10<K4≤100.

[0085] S307: Determine the speed adjustment amount of the indoor unit according to the target air volume and the speed of the indoor fan, and adjust the speed of the indoor unit based on the adjustment amount.

[0086] In some implementations, the speed adjustment amount of the indoor unit in the heating mode can be calculated by the target air volume that the indoor unit needs to compensate and the current speed of the indoor fan. The formula for calculating the speed adjustment amount of the indoor unit in the heating mode is as follows:

[0087] η2=K5Q d2 / r2 2 (5)

[0088] Among them, η2 is the speed adjustment amount of the indoor unit in the heating mode, r2 is the current speed of the indoor fan in the heating mode, K5 is the calculation coefficient, and 1<K5≤30.

[0089] Furthermore, according to the speed adjustment amount of the indoor unit, the size of the windshield of the indoor unit to be adjusted is determined, and the speed of the indoor unit is adjusted by adjusting the windshield of the indoor unit. By increasing the speed of the indoor unit through control execution, the heating capacity of the air conditioner is improved, the comfort effect is improved, and energy consumption is reduced.

[0090] For example, when the air conditioner is heating, the windshield size F of the indoor unit of the air conditioner is detected. d , Sweep air position S t (up and down, left and right), among which, the wind speed size is divided into low speed, medium speed, high speed, ultra-high speed, etc. If the current wind speed size of the indoor unit is low speed, the speed adjustment amount of the indoor unit is used to determine that the wind speed size of the indoor unit needs to be adjusted to ultra-high speed, and then the speed of the indoor unit is adjusted, and the wind sweeping position remains unchanged.

[0091] In the air volume control method of the air conditioner provided in the embodiment of the present application, the target state information of the indoor unit and the current operation mode of the air conditioner are determined, and the target air volume that needs to be compensated indoors is determined according to the operation mode and the target state information. Further, the speed adjustment amount of the indoor unit is determined according to the target air volume and the current speed of the indoor fan, and then the speed of the indoor unit is adjusted. By increasing the speed of the indoor unit, air volume control is achieved to enhance air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, reducing energy consumption, and saving electricity costs.

[0092] Based on the above embodiments, the embodiments of the present application can explain how to determine the dew point temperature of the air conditioner in the cooling mode, such as Figure 4 As shown, the process of determining the dew point temperature of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0093] S401, obtaining target state information of the indoor unit.

[0094] S402, determining the dew point temperature of the air conditioner based on the indoor temperature and the inner pipe temperature.

[0095] In some implementations, if the air conditioner collects the indoor temperature and the inner tube temperature through one or more sensors of the air conditioner, the indoor temperature and the inner tube temperature of the evaporator in the indoor unit are used as the target state information of the indoor unit, and then the dew point temperature of the air conditioner is calculated based on the indoor temperature and the inner tube temperature. The formula for calculating the dew point temperature is as follows:

[0096] T d =mT n +n(T n -T e ) (6)

[0097] Among them, T d is the dew point temperature, T n is the indoor temperature, T e is the temperature of the inner tube of the evaporator, m and n are calculation coefficients, and 0<m≤1, 10≤n≤30.

[0098] It is understandable that after the dew point temperature of the air conditioner is obtained based on the indoor temperature and the inner pipe temperature, steps S303 to S307 may be performed to adjust the rotation speed of the indoor unit.

[0099] In the air volume control method of the air conditioner provided in the embodiment of the present application, the dew point temperature of the air conditioner is calculated by obtaining the indoor temperature and the inner tube temperature of the indoor unit, and the target air volume that needs to be compensated indoors is determined according to the dew point temperature. Further, the speed adjustment amount of the indoor unit is determined according to the target air volume and the current speed of the indoor fan, and then the speed of the indoor unit is adjusted. By increasing the speed of the indoor unit, air volume control is achieved to enhance air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, reducing energy consumption, and saving electricity costs.

[0100] Based on the above embodiments, the embodiments of the present application can explain how to determine the dew point temperature of the air conditioner in the cooling mode, such as Figure 5 As shown, the process of determining the dew point temperature of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0101] S501, obtaining target state information of the indoor unit.

[0102] S502, determining the dew point temperature of the air conditioner based on the indoor humidity and the internal pipe temperature.

[0103] In some implementations, if the air conditioner collects the indoor humidity of the indoor unit and the inner tube temperature of the evaporator in the indoor unit through one or more sensors of the air conditioner as the target state information of the indoor unit, the dew point temperature of the air conditioner can be calculated based on the indoor humidity and the inner tube temperature of the evaporator. The formula for calculating the dew point temperature is as follows:

[0104] T d =T n +Φr(7)

[0105] Among them, Φr is the air humidity, T d is the dew point temperature, T n is the indoor temperature, m and n are calculation coefficients, and 0<m≤1, 10≤n≤30.

[0106] In some implementations, if the air conditioner collects the indoor temperature, indoor humidity and the inner tube temperature of the evaporator in the indoor unit through one or more sensors of the air conditioner, the temperature is used as the target state information of the indoor unit.

[0107] It is understandable that, since the cooling mode of the air conditioner can achieve the effect of dehumidification, the indoor humidity can more accurately represent the dew point temperature of the air conditioner. Therefore, when the indoor humidity and indoor temperature are collected at the same time, the dew point temperature of the air conditioner is calculated based on the indoor humidity and the inner tube temperature of the evaporator in the indoor unit according to the above formula (7).

[0108] It is understandable that after the dew point temperature of the air conditioner is obtained based on the indoor humidity and the inner tube temperature, steps S303 to S307 may be performed to adjust the rotation speed of the indoor unit.

[0109] In the air volume control method of the air conditioner provided in the embodiment of the present application, the indoor humidity temperature and the internal pipe temperature are determined by obtaining the target state information of the indoor unit, the dew point temperature of the air conditioner is calculated, and the target air volume that needs to be compensated indoors is determined according to the dew point temperature. Further, the speed adjustment amount of the indoor unit is determined according to the target air volume and the current speed of the indoor fan, and then the speed of the indoor unit is adjusted. By increasing the speed of the indoor unit, the air volume control is achieved to enhance the air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, reducing energy consumption, and saving electricity costs.

[0110] Figure 6 is a flow chart of a method for controlling the air volume of an air conditioner according to an exemplary embodiment. Figure 6 As shown, the air volume control method of the air conditioner in the embodiment of the present application includes but is not limited to the following steps:

[0111] S601, for an outdoor unit, obtaining target state information of the outdoor unit.

[0112] In some implementations, the outdoor temperature of the outdoor unit and the external tube temperature of the condenser in the outdoor unit may be acquired through one or more temperature sensors of the air conditioner itself as the target state information of the outdoor unit.

[0113] S602: If the air conditioner is in cooling mode, a second hot air density reduction amount when the outdoor air circulates is determined based on the outdoor temperature and the external pipe temperature.

[0114] In some implementations, it is determined that the current operation mode of the air conditioner is the cooling mode, and based on the outdoor temperature and the condenser outer tube temperature, the second hot air density reduction amount during indoor air circulation can be calculated. The formula for calculating the second hot air density reduction amount is as follows:

[0115] Δρ2=K6(c2T p -d2T w ) (8)

[0116] Where Δρ2 is the second hot air density reduction, T w is the outdoor temperature, T p is the outer tube temperature of the condenser, K6, c2, d2 are calculation coefficients, and 10<K6≤100, 0<c2≤d2≤10.

[0117] S603: A third air volume that needs to be increased under the same noise condition is estimated according to the second hot air density reduction amount as the target air volume that the outdoor unit needs to compensate.

[0118] It is understandable that in cooling mode, the air conditioner uses the outdoor unit to exhaust hot air into the room. Due to the influence of temperature, the distance between air molecules increases, resulting in a decrease in the density of outdoor air. The outdoor unit needs to provide a larger air volume to maintain the circulation and cooling effect of indoor and outdoor air. Therefore, the third air volume can be used as the target air volume that the outdoor unit needs to compensate.

[0119] In some implementations, the third air volume that needs to be increased under the same noise can be calculated based on the second hot air density reduction, and used as the target air volume that the indoor unit needs to compensate in the cooling mode. The formula for calculating the third air volume is as follows:

[0120] Q p1 =K7Δρ2 (9)

[0121] Among them, Q p1 is the third air volume, K7 is the calculation coefficient, and 10<K7≤100.

[0122] S604: Determine the speed adjustment amount of the outdoor unit according to the target air volume and the speed of the indoor fan, and adjust the speed of the outdoor unit based on the adjustment amount.

[0123] In some implementations, the speed adjustment amount of the outdoor unit in the cooling mode can be calculated by the target air volume that the outdoor unit needs to compensate and the current speed of the indoor fan. The formula for calculating the speed adjustment amount of the outdoor unit in the cooling mode is as follows:

[0124] η3=K8Q p1 / r3 2 (10)

[0125] Among them, η3 is the speed adjustment amount of the outdoor unit in the cooling mode, r3 is the current speed of the indoor fan in the cooling mode, K8 is the calculation coefficient, and 1<K8≤30.

[0126] Furthermore, according to the speed adjustment amount of the outdoor unit, the size of the windshield that needs to be adjusted for the outdoor unit is determined, and the speed of the outdoor unit is adjusted by adjusting the windshield of the outdoor unit. By increasing the speed of the outdoor unit through control execution, the air conditioning refrigeration capacity is improved, the comfort effect is improved, and energy consumption is reduced.

[0127] For example, when the air conditioner is in cooling mode, the windshield size F of the outdoor unit of the air conditioner is detected. w , Sweep air position S t (up and down, left and right), among which, the wind speed size is divided into low speed, medium speed, high speed, ultra-high speed, etc. If the current wind speed size of the outdoor unit is medium speed, the speed adjustment amount of the outdoor unit is used to determine that the wind speed size of the outdoor unit needs to be adjusted to ultra-high speed, and then the speed of the outdoor unit is adjusted, and the wind sweeping position remains unchanged.

[0128] S605: If the air conditioner is in the heating mode, determine the indoor resistance when increasing indoor air circulation based on the outdoor temperature and the external pipe temperature.

[0129] In some implementations, it is determined that the current operation mode of the air conditioner is the heating mode, and based on the outdoor temperature and the condenser outer tube temperature, the indoor resistance when the indoor air circulation is increased can be calculated. The formula for calculating the indoor resistance is as follows:

[0130] F 阻 =K9(a2T p -b2T w ) (11)

[0131] Among them, F 阻 Indoor resistance when adding air circulation in the heating mode, T w is the outdoor temperature, T p is the outer tube temperature of the condenser, K8, a2, b2 are calculation coefficients, and 0<K9≤100, 0<a2≤b2≤10.

[0132] S606, a fourth air volume that needs to be increased under the same noise condition is estimated according to the indoor resistance, and is used as the target air volume that the outdoor unit needs to compensate.

[0133] In some implementations, the fourth air volume that the outdoor unit needs to increase under the same noise can be calculated based on the indoor resistance when the indoor air circulation is increased, and used as the target air volume that the outdoor unit needs to compensate in the heating mode. The formula for calculating the fourth air volume is as follows:

[0134] Q p2 =K8K 10 (a2T p -b2T w ) (12)

[0135] Among them, Q p2 is the fourth air volume, K 10 is the calculation coefficient, and 10<K9≤100.

[0136] S607: Determine the speed adjustment amount of the outdoor unit according to the target air volume and the speed of the indoor fan, and adjust the speed of the outdoor unit based on the adjustment amount.

[0137] In some implementations, the speed adjustment amount of the outdoor unit in the heating mode can be calculated by the target air volume that the outdoor unit needs to compensate and the current speed of the indoor fan. The formula for calculating the speed adjustment amount of the outdoor unit in the heating mode is as follows:

[0138] η4=K 11 Q p2 / r4 2 (13)

[0139] Among them, η4 is the speed adjustment of the outdoor unit in heating mode, r4 is the current speed of the indoor fan in cooling mode, K 11 is the calculation coefficient, and 1<K 11 ≤30.

[0140] Furthermore, according to the speed adjustment amount of the outdoor unit, the size of the windshield that needs to be adjusted for the outdoor unit is determined, and the speed of the outdoor unit is adjusted by adjusting the windshield of the outdoor unit. By increasing the speed of the outdoor unit through control execution, the heating capacity of the air conditioner is improved, the comfort effect is improved, and energy consumption is reduced.

[0141] For example, when the air conditioner is heating, the windshield size F of the air conditioner outdoor unit is detected. w , Sweep air position S t (up and down, left and right), among which, the wind speed size is divided into low speed, medium speed, high speed, ultra-high speed, etc. If the current wind speed size of the outdoor unit is high speed, the speed adjustment amount of the outdoor unit is used to determine that the wind speed size of the outdoor unit needs to be adjusted to ultra-high speed, and then the speed of the outdoor unit is adjusted, and the wind sweeping position remains unchanged.

[0142] In the air volume control method of the air conditioner provided in the embodiment of the present application, the target state information of the outdoor unit and the current operation mode of the air conditioner are determined, and the target air volume that needs to be compensated indoors is determined according to the operation mode and the target state information. Further, the speed adjustment amount of the outdoor unit is determined according to the target air volume and the current speed of the indoor fan, and then the speed of the outdoor unit is adjusted. By increasing the speed of the outdoor unit, air volume control is achieved to enhance air circulation, thereby improving the cooling or heating capacity of the air conditioner, improving the comfort of the indoor environment, reducing energy consumption, and saving electricity costs.
