[0002] During the operation of an air conditioner, the indoor heat exchanger is in a heat exchange state, and the indoor fan can drive the indoor air to exchange heat with the indoor heat exchanger to increase the temperature of the indoor air.

[0003] In related technologies, indoor fans are generally operated at a fixed speed or with simple PID control based on the indoor ambient temperature. However, this approach cannot effectively balance indoor comfort and air conditioning energy efficiency. Summary of the Invention

When the operating time of the heat exchange mode is greater than or equal to the target duration, the operating speed of the indoor fan is adjusted according to the indoor ambient temperature of the indoor space regulated by the air conditioner.

[0006] In one embodiment, when the heat exchange mode is a heating mode, the step of adjusting the operating speed of the indoor fan according to the indoor ambient temperature of the indoor space regulated by the air conditioner when the running length of the heat exchange mode is greater than or equal to the target running length includes: If the running time of the heating mode is greater than or equal to the target duration, the current indoor ambient temperature of the indoor space is detected to obtain a first ambient temperature; When the first ambient temperature is greater than the set temperature of the air conditioner, the indoor fan is controlled to run at a second speed greater than the second preset speed, and the current indoor ambient temperature of the indoor space is detected to obtain the second ambient temperature; The indoor fan speed is adjusted based on the temperature difference between the second ambient temperature and the set temperature.

[0023] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The main solution of this application embodiment is: when the air conditioner is in heat exchange mode, the operating speed of the indoor fan is adjusted according to the coil temperature of the indoor heat exchanger; when the running time of the heat exchange mode is greater than or equal to the target time, the operating speed of the indoor fan is adjusted according to the indoor ambient temperature of the indoor space regulated by the air conditioner.

[0025] In this embodiment, for ease of description, the following description uses an air conditioner as the subject of execution.

[0026] In related technologies, during the heat exchange operation of air conditioners, the indoor fan generally operates at a fixed speed or is simply adjusted by PID based on the indoor ambient temperature. However, this approach cannot effectively balance indoor comfort and air conditioning energy efficiency.

[0027] This application provides the above solution, which, during the heat exchange mode of the air conditioner, firstly, adjusts the operating speed of the indoor fan based on the coil temperature of the indoor heat exchanger during the rapid temperature adjustment phase, ensuring that the indoor heat exchanger can maintain operation in the high-efficiency temperature range, thereby achieving rapid indoor temperature adjustment while optimizing system operating energy efficiency. When the heat exchange mode operation time reaches the target time, the operating speed of the indoor fan is then adjusted based on the indoor ambient temperature, maintaining indoor comfort while improving air conditioning energy efficiency. Based on this, by adjusting the indoor fan speed in stages in the above manner, it is possible to achieve a balance between improving indoor comfort and air conditioning energy efficiency.

[0028] This application provides an air conditioner. The air conditioner can be any type of air conditioner, such as a wall-mounted air conditioner, a floor-standing air conditioner, a window air conditioner, a ceiling-mounted air conditioner, or a multi-split air conditioner.

The indoor heat exchanger 2 is in the condensation state.

[0034] In one feasible implementation, refer to Figure 2 The air conditioner also includes a temperature sensor 8, which is located in the indoor heat exchanger 2 to detect the temperature of the indoor heat exchanger 2.

[0040] Specifically, according to the embodiments disclosed in this application, the method flow described in the following embodiments can be implemented as a computer software program. For example, the embodiments disclosed in this application include a computer program product comprising a computer program carried on a computer-readable medium, the computer program containing program code for performing the methods shown in the flowchart. In such embodiments, the computer program can be downloaded and installed from a network via a communication device, or installed from a storage device. When the computer program is executed by the processor 1001, it performs the functions defined in the control method of the air conditioner of the embodiments disclosed in this application.

[0041] The air conditioner provided in this application, employing the control method of the air conditioner in the following embodiments, can solve the technical problem of how to balance improving indoor comfort and air conditioning energy efficiency. Compared with the prior art, the beneficial effects of the air conditioner provided in this application are the same as those of the control method of the air conditioner provided in the following embodiments, and other technical features of this air conditioner are the same as those disclosed in the method of the following embodiments, and will not be repeated here.

[0042] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or air conditioner capable of performing the above functions. The following description uses an air conditioner as an example to illustrate this embodiment and the subsequent embodiments.

[0043] Based on this, the embodiments of this application provide a control method for an air conditioner, referring to... Figure 3 , Figure 3 This is a flowchart illustrating the first embodiment of the control method for the air conditioner of this application.

[0044] In this embodiment, the control method of the air conditioner includes steps S10 to S20: Step S10: When the air conditioner is in heat exchange mode, the indoor fan speed is adjusted according to the coil temperature of the indoor heat exchanger. In this embodiment, the heat exchange mode is the heating mode, and the indoor heat exchanger is in a condensation state.

[0045] The coil temperature is the current temperature of the indoor heat exchanger detected by the aforementioned temperature sensor. In this embodiment, the coil temperature is the temperature detected by a temperature sensor located in the middle of the indoor heat exchanger, and the detected temperature can be the temperature at the middle of the coil of the indoor heat exchanger. Here, the middle of the indoor heat exchanger refers to the middle of the heat exchange flow path of the indoor heat exchanger.

[0046] Different indoor heat exchanger coil temperatures correspond to different indoor fan operating speeds.

[0047] In this embodiment, the indoor fan speed can be adjusted according to the relationship between the coil temperature and a preset temperature range or a preset temperature threshold, so that the coil temperature of the indoor heat exchanger reaches the preset temperature range or the temperature deviation between the coil temperature and the preset temperature threshold is less than a preset deviation. The preset temperature range can be a target range that the indoor heat exchanger coil temperature needs to reach when the air conditioning energy efficiency is greater than a preset energy efficiency (e.g., reaching the maximum energy efficiency or 70% of the maximum energy efficiency); the preset temperature threshold can be a minimum temperature that the indoor heat exchanger coil temperature needs to reach when the air conditioning energy efficiency is greater than a preset energy efficiency (e.g., reaching the maximum energy efficiency or 70% of the maximum energy efficiency).

[0048] In one implementation, the target speed value of the indoor fan can be determined based on the relationship between the coil temperature of the indoor heat exchanger and a preset temperature range or a preset temperature threshold, and the indoor fan can be controlled to operate at the target speed value. In another implementation, the speed adjustment parameters of the indoor fan can be determined based on the relationship between the coil temperature of the indoor heat exchanger and a preset temperature range or a preset temperature threshold, and the indoor fan can be controlled to increase, decrease, or maintain its speed according to the speed adjustment parameters.

[0049] If the running time of the heat exchange mode is less than the target time, the step of adjusting the operating speed of the indoor fan according to the coil temperature of the indoor heat exchanger can be repeated.

[0050] In this embodiment, the indoor fan speed is adjusted by switching the fan speed.

[0051] Step S20: If the running time of the heat exchange mode is greater than or equal to the target running time, adjust the operating speed of the indoor fan according to the indoor ambient temperature of the indoor space regulated by the air conditioner.

[0052] The target duration is the time required for the heat exchange mode to operate until the indoor ambient temperature reaches the set temperature after the heat exchange mode is activated. The target duration can be a preset fixed duration or a duration determined based on the actual operating conditions of the air conditioner.

[0053] When the heat exchange mode runs for less than the target duration, the indoor ambient temperature is not measured. When the heat exchange mode runs for the target duration, the indoor ambient temperature is measured for the first time. In other words, indoor comfort is assessed only when the heat exchange mode runs for the target duration.

[0054] The indoor fan speed is adjusted according to the indoor ambient temperature and the set temperature of the air conditioner. The indoor fan speed will vary depending on the relationship or temperature difference between the indoor ambient temperature and the set temperature.

[0055] In this embodiment, the operating speed of the indoor fan is greater when the indoor ambient temperature meets the first temperature condition than when the indoor ambient temperature meets the second temperature condition. The first temperature condition indicates that the indoor temperature is maintained at the set temperature, and the second temperature condition indicates that the indoor temperature has not reached the set temperature and deviates from it. In this embodiment, the first temperature condition includes a temperature deviation between the indoor ambient temperature and the set temperature that is less than or equal to a preset deviation, where the temperature deviation is the absolute value of the difference between the indoor ambient temperature and the set temperature. When the heat exchange mode is heating mode, the second temperature condition includes a set temperature greater than the indoor ambient temperature and a temperature deviation between the set temperature and the indoor ambient temperature greater than the preset deviation (i.e., the temperature difference between the set temperature and the indoor ambient temperature is greater than the preset temperature difference). When the heat exchange mode is cooling mode, the second temperature condition includes an indoor ambient temperature greater than the set temperature and a temperature deviation between the set temperature and the indoor ambient temperature greater than the preset deviation (i.e., the temperature difference between the indoor ambient temperature and the set temperature is greater than the preset temperature difference).

[0056] In this embodiment, when the running time of the heat exchange mode is greater than or equal to the target time, the indoor ambient temperature can be detected at set intervals, and the indoor fan speed can be adjusted according to the indoor ambient temperature.

[0057] In this embodiment, the indoor fan speed is adjusted by switching the fan speed.

[0058] This embodiment provides a control method for an air conditioner. During the heat exchange mode, the operating speed of the indoor fan is first adjusted based on the coil temperature of the indoor heat exchanger during the rapid temperature adjustment phase. This ensures the indoor heat exchanger operates within its high-efficiency temperature range, achieving rapid indoor temperature adjustment while optimizing system energy efficiency. Once the heat exchange mode operation reaches the target duration, the operating speed of the indoor fan is then adjusted based on the indoor ambient temperature to maintain indoor comfort while improving air conditioning energy efficiency. By adjusting the indoor fan speed in stages according to this method, both indoor comfort and air conditioning energy efficiency can be improved. However, using the inlet or outlet temperature of the heat exchanger to adjust the indoor fan speed can lead to inaccurate or untimely control. Using a temperature sensor located in the middle of the indoor heat exchanger to detect the coil temperature improves the accuracy of indoor fan speed control, thereby further enhancing air conditioning energy efficiency and indoor comfort.

[0059] In this embodiment, the application of the air conditioner control method in the heating mode, compared with simply using PID control of the indoor fan speed based on the indoor ambient temperature throughout the entire heating mode operation, can improve the heating energy efficiency of the air conditioner from 2.883 to 3.382, an energy efficiency improvement of 0.499 (17.3%).

[0060] In one feasible implementation, when the heat exchange mode is a heating mode, the step of controlling the indoor fan speed to adjust based on the coil temperature of the indoor heat exchanger when the air conditioner is in heat exchange mode includes: During the process of the indoor heat exchanger coil temperature rising, the indoor fan speed is increased; when the indoor heat exchanger coil temperature rises to the second preset temperature, the indoor heat exchanger coil temperature is detected every set time interval; when the detected coil temperature shows a downward trend and continues for a preset time interval, the indoor fan speed is reduced.

[0061] In the initial stage of heating, the temperature of the indoor heat exchanger coil will gradually rise. As the coil temperature rises, the operating speed of the indoor fan will increase, eventually reaching the maximum speed of the indoor fan.

[0062] The second preset temperature is the minimum coil temperature required for the indoor heat exchanger to achieve a heating efficiency greater than the preset efficiency. The range of the second preset temperature can be [39℃, 42℃], for example, the second preset temperature can be 41℃, etc. The second preset temperature may vary depending on the model of the air conditioner.

[0063] If the coil temperature of the indoor heat exchanger shows a decreasing trend for a continuous preset time after reaching the second preset temperature, it can be considered that the heat exchange capacity of the air conditioner and the load have reached a critical balance point. At this time, the air volume is reduced by reducing the speed of the indoor fan to ensure that the actual heat exchange capacity of the air conditioner matches the load and improve the air conditioning energy efficiency.

[0064] The indoor fan speed is reduced according to a first speed adjustment parameter. The first speed adjustment parameter may include a speed adjustment ratio, a speed adjustment amplitude, or a speed adjustment rate. In this embodiment, the first speed adjustment parameter is a speed adjustment ratio, which is the ratio of the adjusted speed to the original speed. The value range of the speed adjustment ratio can be [75%, 85%], for example, a speed adjustment ratio of 80%.

[0065] As the coil temperature decreases, the operating speed of the indoor fan decreases linearly with the decrease in coil temperature, or the fan speed of the indoor fan decreases linearly with the decrease in coil temperature.

[0066] In this embodiment, as the coil temperature decreases from the second preset temperature to the third preset temperature, the indoor fan speed gradually decreases. When the coil temperature is lower than the third preset temperature, the indoor fan speed drops sharply, operating at its lowest speed. The first preset temperature is lower than the third preset temperature, and the second preset temperature is higher than the third preset temperature.

[0067] In this embodiment, based on the above method, the heat from the indoor heat exchanger can be fully used to heat the indoor space, thereby improving the air conditioning energy efficiency and achieving a rapid increase in indoor temperature to enhance indoor comfort.

[0068] In one feasible implementation, the step of controlling the indoor fan to adjust its operating speed according to the coil temperature of the indoor heat exchanger when the air conditioner is in heat exchange mode further includes: when the air conditioner is in heating mode, controlling the indoor fan to operate at a first speed less than or equal to a first preset speed; and when the coil temperature of the indoor heat exchanger rises to the first preset temperature, performing the step of controlling the indoor fan to increase its speed during the rise of the coil temperature of the indoor heat exchanger; wherein the first preset temperature is less than the second preset temperature.

[0069] The first preset temperature is the minimum temperature that the indoor heat exchanger needs to reach to prevent the air conditioner from blowing out cold air. The value range of the first preset temperature can be [26℃, 30℃], for example, the first preset temperature can be 28℃, etc. The first preset temperature may be different depending on the model of the air conditioner.

[0070] When the indoor fan operates at a first preset speed, it is in a low-speed state. The first preset speed can be [20%, 40%] of the maximum allowable operating speed of the indoor fan. The first speed can be a pre-set fixed speed. For example, if the indoor fan operates at the lowest speed (lowest fan setting), the air conditioner will output air at the lowest air volume. Alternatively, the first speed can also be a speed determined based on the actual operating conditions of the air conditioner.

[0071] In this embodiment, during the start-up phase of the heating mode, the indoor fan operates at a low speed, which helps the temperature in the middle of the indoor heat exchanger to rise quickly to the first preset temperature, thereby effectively preventing the air conditioner in heating mode from blowing out cold air and improving indoor heating comfort.

[0072] In one feasible implementation, when the heat exchange mode is a heating mode, the step of adjusting the operating speed of the indoor fan according to the indoor ambient temperature of the indoor space regulated by the air conditioner when the running length of the heat exchange mode is greater than or equal to the target running length includes: when the running length of the heating mode is greater than or equal to the target running length, detecting the current indoor ambient temperature of the indoor space to obtain a first ambient temperature; when the first ambient temperature is greater than the set temperature of the air conditioner, controlling the indoor fan to run at a second speed greater than a second preset speed, and detecting the current indoor ambient temperature of the indoor space to obtain a second ambient temperature; controlling the indoor fan to adjust its operating speed according to the temperature difference between the second ambient temperature and the set temperature.

[0073] When the indoor fan operates at the second speed, it is in a high-speed state, which can be [70% or 90%] of the maximum allowable operating speed of the indoor fan. The second speed can be a preset fixed speed; for example, if the indoor fan operates at its highest speed, the air conditioner will output air at its maximum volume. Alternatively, the second speed can also be a speed determined based on the actual operating conditions of the air conditioner.

[0074] When the first ambient temperature is less than or equal to the set temperature, the indoor fan can be controlled to maintain the current speed or reduce the speed and then return to the step of detecting the current indoor ambient temperature of the indoor space to obtain the first ambient temperature.

[0075] In this embodiment, when the indoor fan is running at a high speed (second speed), if the temperature difference between the set temperature of the air conditioner and the indoor ambient temperature is greater than a preset temperature difference, the indoor fan speed is controlled to decrease; if the temperature difference between the set temperature and the second ambient temperature is greater than a preset temperature difference, the indoor fan speed is controlled to decrease; if the temperature deviation between the set temperature and the second ambient temperature is less than or equal to the preset temperature difference, the indoor fan speed is controlled to maintain its current speed. The temperature deviation is the absolute value of the difference between the set temperature and the second ambient temperature, and the temperature difference is the difference between the set temperature and the second ambient temperature. The preset temperature difference is greater than 0°C. When the temperature deviation is less than or equal to the preset temperature difference, the indoor temperature is stable; when the temperature difference is greater than the preset temperature difference, it indicates that the set temperature is much higher than the indoor ambient temperature, indicating a risk of heat loss indoors. In this case, reducing the indoor fan speed helps reduce the feeling of cold air from the air conditioner and increases the temperature of the indoor heat exchanger to ensure the outlet air temperature. Therefore, this helps reduce fluctuations in both the outlet air temperature and the indoor temperature.

[0076] In this embodiment, the indoor temperature comfort is judged for the first time when the running time of the heating mode reaches the target time. When the first ambient temperature reaches or exceeds the set temperature, the indoor fan runs at a high speed, which can ensure that the air conditioner can output high heating capacity and effectively improve the system energy efficiency ratio under this condition. Thereafter, the operating speed of the indoor fan is steadily controlled based on the temperature difference between the indoor ambient temperature and the set temperature, thereby improving the air conditioner's energy efficiency and the stability of the indoor temperature.

[0079] Based on any of the above embodiments, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, refer to... Figure 5 The control method for the air conditioner further includes: Step S100: Obtain the initial temperature of the indoor space when the heat exchange mode is activated; The initial temperature is the temperature of the indoor space detected at the start of the heat exchange mode.

[0080] Step S200: Determine the predicted time required for the indoor space to reach the set temperature from the initial temperature based on the initial temperature and the set temperature of the air conditioner, wherein the target time is the predicted time.

[0081] Different initial temperatures and different set temperatures correspond to different prediction durations.

[0082] A pre-established correspondence between initial temperature, set temperature, and prediction duration is created. This correspondence can include formulas, mappings, or machine learning models. Based on this correspondence, the prediction duration corresponding to the current initial and set temperatures can be determined. For example, the initial and set temperatures can be substituted into a pre-defined formula to calculate the prediction duration. Alternatively, the temperature difference between the set and initial temperatures can be determined, and the prediction duration can be determined based on the temperature difference range within which the difference falls.

[0083] In this embodiment, the outdoor ambient temperature of the environment where the air conditioner is located can also be obtained, the total power consumption of the air conditioner during the process of raising the indoor space from the initial temperature to the set temperature can be determined, the indoor and outdoor heat exchange temperature difference can be determined based on the initial temperature, the set temperature and the outdoor ambient temperature, and the prediction duration can be determined based on the outdoor ambient temperature, the total power consumption and the thermal inertia coefficient of the indoor space.

[0084] In determining the total power consumption, it can be obtained from actual measured power consumption data; alternatively, it can be determined based on the initial temperature and the set temperature. A preset correspondence between the initial temperature, the set temperature, and the total power consumption can be established in advance. This preset correspondence can include mapping tables, formulas, etc. Based on this preset correspondence, the total power consumption corresponding to the current initial temperature and set temperature can be determined. For example, the total power consumption can be obtained by looking up a table using the initial temperature and the set temperature.

[0085] The indoor-outdoor heat exchange temperature difference is the temperature difference between the indoor space and the outdoor environment per unit time after the heating mode is started. In the process of determining the indoor-outdoor heat exchange temperature difference during heating mode, the average value of the initial temperature and the set temperature is determined, and the difference between the average value and the outdoor ambient temperature is determined as the indoor-outdoor heat exchange temperature difference.

[0086] In this embodiment, the heat loss of the indoor space is determined based on the total power consumption and the thermal inertia coefficient; the prediction duration is determined based on the ratio of the heat loss to the indoor-outdoor heat exchange temperature difference. The heat loss is the heat lost during heat exchange between the indoor and outdoor environments. The heat loss can be the difference between the total heat exchange output by the air conditioner and the actual heat exchange during the air conditioner's operation in heat exchange mode. The actual heat exchange is the heat actually used for temperature regulation of the indoor space; for example, in heating mode, the actual heat exchange is the heat actually used to raise the indoor space temperature.

[0087] In this embodiment, the ratio of heat loss to the indoor-outdoor heat exchange temperature difference is used as the prediction duration. In other implementations, the prediction duration can also be obtained by correcting the ratio with a correction factor.

[0088] In one application example, the relationship between the thermal inertia coefficient, prediction duration, indoor-outdoor heat exchange temperature difference, and total power consumption is as follows: Etotal = K * (T1) avg – T 4,avg ) * t total Where Etotal is the total power consumption, t total For the predicted duration, K is the thermal inertia coefficient, and T is... 4,avg The outdoor ambient temperature, T1 avg For the average value, (T1) avg – T 4,avg () represents the temperature difference between indoor and outdoor heat exchange.

[0089] In this embodiment, based on the above method, it is only necessary to detect the initial temperature of the indoor space at the start of the heat exchange mode to accurately predict when the indoor space temperature will reach the set temperature, thereby realizing the accurate switching of the indoor fan speed regulation from based on the coil temperature to based on the indoor ambient temperature, so as to achieve the best balance between indoor temperature comfort and air conditioning energy efficiency.

[0090] In other embodiments, instead of calculating heat loss, the quantitative relationship between total power consumption, thermal inertia coefficient, initial temperature, and set temperature can be directly established, and the predicted duration can be calculated based on this quantitative relationship and the parameters obtained above.

[0091] In one feasible implementation, before the step of determining the predicted duration based on the indoor-outdoor heat exchange temperature difference, the total power consumption, and the thermal inertia coefficient of the indoor space, the method further includes: acquiring historical data from multiple previous heat exchange modes of the air conditioner, obtaining multiple historical data, the historical data including outdoor temperature, and indoor temperature, total power consumption, and total duration during the process of the indoor space increasing from the corresponding initial room temperature to the corresponding target temperature; determining a second temperature difference value between each indoor temperature and the corresponding outdoor temperature, determining a corresponding historical heat loss based on each second temperature difference value and the corresponding total duration; determining a corresponding thermal inertia coefficient reference value based on the ratio of the total power consumption to the historical heat loss for each historical data, and determining the thermal inertia coefficient based on the multiple thermal inertia coefficient reference values ​​corresponding to the multiple historical data.

[0092] The target temperature is the desired temperature level for the indoor space during the operation of this heat exchange mode. The indoor temperature is the average temperature of the indoor space during the corresponding process. The outdoor temperature is the average temperature of the outdoor environment during the corresponding process. The initial room temperature corresponds to the initial indoor space temperature when this heat exchange mode is started.

[0093] Each heat exchange mode corresponds to a historical data set that defines a second temperature difference value, a historical heat loss, and a thermal inertia coefficient reference value. The second temperature difference value corresponds to the indoor-outdoor heat exchange temperature difference during the operation of that heat exchange mode. The product of the second temperature difference value and the total duration can be used as the historical heat loss. In this embodiment, the ratio of the total power consumption to the historical heat loss is used as the thermal inertia coefficient reference value.

[0094] After obtaining multiple thermal inertia coefficient reference values, the average value of the multiple thermal inertia coefficient reference values ​​can be used as the thermal inertia coefficient, or the multiple thermal inertia coefficient reference values ​​can be smoothed and filtered to obtain the thermal inertia coefficient.

[0095] In one application example, the relationship between the thermal inertia coefficient reference value, total duration, second temperature difference value, and total power consumption is as follows: Etotal' = K' * (T1) avg ' – T 4,avg ') * t total ', where Etotal' is the total power consumption, t total ' represents the total duration, K' is the reference value for the thermal inertia coefficient, and T... 4,avg 'T1 represents the outdoor temperature.' avg ' is the indoor temperature, (T1) avg ' – T 4,avg ') represents the second temperature difference value.

[0096] In this embodiment, by analyzing historical data from multiple runs of the heat exchange mode of the air conditioner, the thermal inertia coefficient of the indoor space can be accurately determined. Based on the thermal inertia coefficient, the time when the set temperature is reached after the current heat exchange mode is started can be accurately predicted, so as to achieve accurate control of the indoor fan speed in stages, and further improve the balance between indoor comfort and air conditioning energy efficiency.

[0097] In other embodiments, the thermal inertia coefficient can also be a pre-set fixed parameter. Based on this parameter, a correspondence between the initial temperature, the set temperature and the prediction duration can be directly established, and the prediction duration corresponding to the current initial temperature and the set temperature can be determined based on this correspondence.

[0098] In one feasible implementation, a preset correspondence relationship between the initial temperature, the set temperature and the total power consumption is established based on the initial room temperature, the target temperature and the total power consumption corresponding to multiple historical data; the step of determining the total power consumption of the air conditioner during the process of raising the indoor space from the initial temperature to the set temperature includes: determining the total power consumption based on the preset correspondence relationship, according to the initial temperature and the set temperature.

[0099] In this embodiment, by means of the above method, during the operation of this heat exchange mode, there is no need to detect the power consumption. The power consumption required to raise the temperature to the set temperature in this heat exchange mode can be obtained quickly and accurately. This effectively controls efficiency while ensuring the accuracy of fan control, so as to ensure the matching of power consumption and power consumption required to raise the temperature, and further improve the effect of both indoor comfort and air conditioning energy efficiency.
