[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] The main solution of an embodiment of the present invention is: the air conditioner includes a shell and an air guide component, the shell is provided with an air outlet, the air guide component is arranged on the shell and corresponding to the air outlet, the air guide component includes a first air dispersing plate and a second air dispersing plate, based on this air conditioner, when the air conditioner is in cooling operation, the air guide component is controlled to operate in a target air guiding state, and the indoor heat exchanger temperature and the indoor dew point temperature are obtained; the target frequency of the compressor is determined according to the indoor heat exchanger temperature and the indoor dew point temperature; the compressor is controlled to operate at the target frequency; wherein, the target air guiding state is that the first air dispersing plate blocks the air outlet, and the second air dispersing plate blocks the airflow in the shell blowing toward the first air dispersing plate, and the wind speed of the indoor environment in the target air guiding state is less than the set wind speed threshold, and the wind feeling index of the indoor environment is less than the set wind feeling index threshold.

[0052] In the prior art, when the comfortable wind mode is in operation, the wind speed at the air outlet is low, and the cooling capacity of the air outlet is slowly dissipated when the air conditioner is in cooling operation. Excessive cooling capacity can easily lead to a large temperature difference between the inside and outside of the air outlet, causing condensation at the air outlet and affecting the normal operation of the air conditioner.

[0053] The present invention provides the above-mentioned solution, aiming to prevent condensation from occurring at the air outlet of the air conditioner in the comfortable wind mode.

[0054] An embodiment of the present invention provides an air conditioner, which may be a floor-standing air conditioner, a cabinet air conditioner, a window air conditioner, or the like.

[0055] In the embodiment of the present invention, referring to Figure 1 and Figure 2 The air conditioner is a floor-standing air conditioner. Specifically, the air conditioner includes a housing 1, an indoor heat exchanger 7, and an indoor fan 2. The housing 1 is provided with an air inlet and an air outlet, with the air outlet extending along the height of the housing. The number of air outlets can be one or more depending on actual needs. In this embodiment, there are two air outlets, spaced apart horizontally along the air conditioner.

[0056] An air duct connecting the air inlet and the air outlet may be provided within the housing 1, and both the indoor fan 2 and the indoor heat exchanger 7 are disposed within the air duct. When the indoor fan 2 is operating, air from the indoor environment enters the air duct from the air inlet, exchanges heat through the indoor heat exchanger 7, and is then delivered to the indoor environment through the air outlet.

[0057] Further, refer to Figure 1 and Figure 2The air outlet may be provided with a switch door 01. The edge of the air outlet located on the outer surface of the housing 1 can be opened or closed by changing the position of the switch door 01. When the switch door 01 is in the open position, the airflow within the housing 1 can be sent into the indoor environment through the air outlet; when the switch door 01 is closed, the airflow within the housing 1 cannot be sent into the indoor environment through the air outlet.

[0058] Reference Figure 2 The air conditioner further includes an air guide assembly 3, which is provided on the housing 1 and corresponds to the air outlet. Specifically, the air guide assembly 3 includes an air dispersion plate and a swirl module provided on the air dispersion plate, and the air dispersion plate is provided with a plurality of air dispersion holes. Specifically,

[0059] The air dispersion plate includes a first air dispersion plate 31 and a second air dispersion plate 32. Each of the first air dispersion plate 31 and the second air dispersion plate 32 is provided with a plurality of air dispersion holes. The airflow passing through the first air dispersion plate 31 and the second air dispersion plate 32 is dispersed by the air dispersion holes. The air dispersion holes can be grille holes, micropores, or mesh holes. The first air dispersion plate 31 and the second air dispersion plate 32 are both rotatably connected to the housing 1 to open or block the air outlet.

[0060] The second air dispersing plate 32 is fixed relative to the first air dispersing plate 31. As the position of the first air dispersing plate 31 changes, the position of the second air dispersing plate 32 changes accordingly. The first and second air dispersing plates 31, 32 are connected to the housing 1 via a common rotating shaft, which extends along the height of the housing 1. Due to the different rotational positions of the second air dispersing plate 32 and the first air dispersing plate 31, their positions relative to the air outlet differ, resulting in different air guiding states of the air guide assembly 3.

[0061] In this embodiment, the air guide assembly 3 has a first air guide state and a second air guide state, and the air guide assembly 3 can be switched between the first air guide state and the second air guide state by rotation. The air outlet speed corresponding to the first air guide state is less than or equal to the set air speed, and the air outlet speed corresponding to the second air guide state is greater than the set air speed.

[0062] In the first air-guiding state, the first and second air-dispersing plates 31, 32 are in the first air-guiding position and cooperate to block the air outlet. Specifically, the first air-dispersing plate 31 blocks the air outlet, and the second air-dispersing plate 32 is located in the housing 1 in a wind-blocking state. At this time, the second air-dispersing plate 32 blocks the airflow from the housing 1 that is directed toward the first air-dispersing plate 31. When the first air-dispersing plate 31 completely blocks the air outlet, the edge of the first air-dispersing plate 31 seals the edge of the air outlet, and all airflow is delivered into the room through the first air-dispersing plate 31. Therefore, after heat exchange at the indoor heat exchanger 7, the airflow that needs to be delivered into the room from the air outlet is first dispersed through the air-dispersing holes on the second air-dispersing plate 32, and then further dispersed through the air-dispersing holes on the first air-dispersing plate 31 before being delivered into the room. At this time, the air conditioner has a relatively small air volume and wind speed, and the wind sensation felt by the user is relatively weak.

[0063] In the second air-guiding state, the second air-dispersing plate 32 and the first air-dispersing plate 31 are in the second air-guiding position, and the air outlet is open. Specifically, the second air-dispersing plate 31 and the second air-dispersing plate 32 are both located within the housing 1, the second air-dispersing plate 32 is spaced from the edge of the air outlet, and the first air-dispersing plate 31 is located inside the second air-dispersing plate 32. At this point, the first air-dispersing plate 31 and the second air-dispersing plate 32 cooperate to open the air outlet, and airflow within the housing 1 is delivered into the indoor environment through the gap between the second air-dispersing plate 32 and the edge of the air outlet. It should be noted that the distance between the first air-dispersing plate 31 and the air outlet is greater than the distance between the second air-dispersing plate 32 and the air outlet. Therefore, a small portion of the airflow that needs to be delivered to the indoor environment from the air outlet after heat exchange in the indoor heat exchanger 7 can be dispersed through the two air-dispersing plates before being delivered to the indoor environment. The majority of the airflow is delivered directly into the indoor environment through the gap between the second air-dispersing plate 32 and the air outlet. At this point, the air conditioner has a large air volume and speed, and the user experiences a strong wind sensation.

[0064] The first and second air dispersing plates 31, 32 can be configured as flat plates or curved surfaces, depending on actual needs. Specifically, in this embodiment, the two opposing surfaces of the first air dispersing plate 31 are defined as wind guide surfaces. Thus, the wind guide surfaces of the first air dispersing plate 31 are curved surfaces that bulge away from the second air dispersing plate 32, thereby reducing the sense of wind while increasing the air outlet area.

[0065] Specifically, in one embodiment of the air conditioner, the edge of the first air dispersing plate 31 can be connected to the edge of the second air dispersing plate 32, and the surfaces of the two air dispersing plates can enclose a guide cavity. Based on this, when the first air dispersing plate 31 is blocking the air outlet, the airflow dispersed by the second air dispersing plate 32 can be completely converged in the guide cavity and then delivered into the room through the first air dispersing plate 31. This ensures that the two air dispersing plates cooperate to reduce the air velocity at the air outlet while ensuring sufficient cooling output at the air outlet through the convergence effect.

[0066] Further, refer to Figure 3 In addition to the air dispersion holes, the second air dispersion plate 32 may also have ventilation holes. The aperture of the ventilation holes is larger than that of the air dispersion holes. Specifically, the ventilation holes may be equipped with a swirl module, a grille, or a mesh, or may be left empty. In this embodiment, there are multiple ventilation holes, each equipped with a swirl module. The swirl module is used to disperse the passing airflow and blow it toward the surrounding areas of the air outlet when it rotates.

[0067] In this embodiment, the air guide assembly may also include a swirl module 4. The swirl module 4 may be provided on the second air dispersing plate 32 and / or the first air dispersing plate 31 according to actual needs. Specifically, the swirl module 4 may be provided between the first air dispersing plate 31 and the second air dispersing plate 32 or on the side of the first air dispersing plate 31 facing away from the second air dispersing plate 32. The swirl module 4 includes a turntable, which may be provided with vanes, grilles or meshes. When the swirl module 4 rotates, the airflow blown toward the air outlet from the housing 1 or the airflow flowing through the air outlet may be dispersed to the surroundings to further reduce the air velocity of the air outlet; and when the swirl module 4 stops rotating, the airflow may be blown out from between the vanes of the swirl module 4. Among them, the air velocity of the air outlet when the swirl module 4 stops rotating is greater than the air velocity of the air outlet when the swirl module 4 rotates.

[0068] Specifically, in one embodiment of the air conditioner, the swirl module 4 includes a first rotor and a second rotor arranged opposite each other. The first rotor includes a plurality of first rotor blades spaced circumferentially, and the second rotor includes a plurality of second rotor blades spaced circumferentially. Specifically, the first rotor is fixed to the ventilation hole, and the second rotor is rotatable relative to the first rotor. Specifically, the first rotor may be provided with a stopper that cooperates with the second rotor. When the first rotor rotates, the second rotor rotates with the first rotor under the restraining action of the stopper. During the synchronous rotation of the first and second rotors, the first and second rotors have a first relative position and a second relative position. The first relative position is where the first and second rotor blades are aligned, and the second relative position is where the first and second rotor blades are offset. The ventilation area of ​​the swirl module corresponding to the first relative position is greater than the ventilation area of ​​the swirl module corresponding to the second relative position. The wind dispersion effect of the swirl module corresponding to the second relative position is better than that of the swirl module corresponding to the first relative position.

[0069] Further, in one embodiment of the air conditioner, referring to Figure 3The second air dispersion plate 32 may also be provided with a connecting rod and a louver 5 connected to the connecting rod on the side facing away from the first air dispersion plate 31. The louver 5 includes multiple guide vanes connected by the connecting rod. Based on this, in the second air-guiding state, the connecting rod can be used to drive the louver 5 to swing back and forth or guide the air at a fixed angle when the connecting rod moves in the up-down direction or left-right direction to adjust the airflow direction of the air outlet. In the first air-guiding state, the airflow volume of the air outlet can be adjusted by setting the louver 5 in the air duct at different angles to the connecting rod. Specifically, when the louver 5 is parallel to the airflow direction in the air duct, the airflow volume of the air outlet is greater than when the louver 5 is in other positions. Specifically, each guide vane can be provided corresponding to a swirl module 4.

[0070] Furthermore, in one embodiment of the air conditioner, the air conditioner further includes an environmental parameter detection module 6. The environmental parameter detection module 6 can be located in the external environment of the air conditioner or on the air conditioner (e.g., at the return air vent of the air conditioner). The environmental parameter detection module 6 can be used to detect the humidity and / or temperature of the air conditioner operating space.

[0071] Furthermore, in one embodiment of the air conditioner, the air conditioner further includes a temperature sensor 8, which is specifically configured to detect the temperature of the indoor heat exchanger 7. In this embodiment, the temperature sensor 8 is disposed on the coil of the indoor heat exchanger 7. In other embodiments, the temperature sensor 8 may also be disposed on the inner wall of the housing 1 near the indoor heat exchanger 7.

[0072] An embodiment of the present invention further provides a control device for an air conditioner, which is used to control the above-mentioned air conditioner. The control device can be built into the air conditioner or independently provided outside the air conditioner according to actual needs.

[0073] In the embodiment of the present invention, referring to Figure 4 The air conditioner control device includes: a processor 1001 (e.g., a CPU), a memory 1002, and a timer 1003. The processor 1001, memory 1002, and timer 1003 may be connected via a communication bus. The memory 1002 may be a high-speed RAM memory or a non-volatile memory such as a disk drive. The memory 1002 may also optionally be a storage device independent of the processor 1001.

[0074] Specifically, the indoor fan 2, air guide assembly 3, swirl module 4, louvers 5, environmental parameter detection module 6, compressor 9, and temperature sensor 8 of the air conditioner are connected to the control device in this embodiment. The control device can be used to control the operation of these components and obtain data on the operation or detection of these components.

[0075] Those skilled in the art will understand that Figure 4The device structure shown in the figure does not constitute a limitation of the device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0076] like Figure 4 As shown, the memory 1002 as a computer readable storage medium may include a control program for the air conditioner. Figure 4 In the device shown, the processor 1001 can be used to call the air conditioner control program stored in the memory 1002 and execute the relevant steps of the air conditioner control method in the following embodiments.

[0077] An embodiment of the present invention further provides a method for controlling an air conditioner, which is applied to control the above-mentioned air conditioner.

[0078] Reference Figure 5 , an embodiment of a control method for an air conditioner of the present application is proposed. In this embodiment, the air conditioner includes a housing and an air guide assembly, the housing is provided with an air outlet, the air guide assembly is provided on the housing and is arranged corresponding to the air outlet, and the control method of the air conditioner includes:

[0079] Step S10, when the air conditioner is in cooling operation, controlling the air guide assembly to operate in a target air guide state, and obtaining an indoor heat exchanger temperature and an indoor dew point temperature; the target air guide state is when the first air diffuser blocks the air outlet, and the second air diffuser blocks the airflow in the housing toward the first air diffuser, and the wind speed of the indoor environment in the target air guide state is less than a set wind speed threshold, and the wind sensation index of the indoor environment is less than a set wind sensation index threshold;

[0080] The target wind guiding state here is the first wind guiding state mentioned in the above embodiment.

[0081] During cooling operation, the indoor heat exchanger is in an evaporating state. Driven by the fan, air passes through the indoor heat exchanger for heat exchange. The air temperature drops after heat exchange and is blown toward the outlet. If the outlet's air guide assembly is in the target air guide state, the airflow toward the outlet is first dispersed by the second air diffuser before being blown toward the first air diffuser. It is then further dispersed by the first air diffuser before being delivered into the room.

[0082] Under the action of the first air dispersion plate and the second air dispersion plate cooperating to disperse the air, the maximum actual wind speed of the indoor environment will not exceed the set wind speed threshold, and the maximum actual wind feeling index of the indoor environment will not exceed the set wind feeling index threshold.

[0083] The set wind speed threshold and / or set wind sensation index threshold here can be user-defined parameters or system default parameters. The set wind sensation index threshold includes a non-steady-state draft index (USDR value) and / or a steady-state draft index (DR value). The non-steady-state draft index refers to the percentage of people dissatisfied with the air conditioner's operating space due to heat loss from the airflow when the air conditioner's operating space is not in a thermally stable state. The steady-state draft index refers to the percentage of people dissatisfied with the air conditioner's operating space due to heat loss from the airflow when the air conditioner's operating space is in a thermally stable state. In this embodiment, the set wind speed threshold has a value range of [0.2 m / s, 0.4 m / s], for example, 0.3 m / s. In other embodiments, the set wind speed threshold can also be set to other values ​​based on actual conditions, such as 0.6 m / s, 0.1 m / s, etc. In this embodiment, the non-steady-state draft index has a value range of [7%, 12%], for example, 10%. In other embodiments, the non-steady-state blowing sensation index can also be set to other numerical parameters according to actual conditions, such as 13%, 15%, etc. In this embodiment, the value range of the non-steady-state blowing sensation index is [2%, 6%], for example, 5%. In other embodiments, the non-steady-state blowing sensation index can also be set to other numerical parameters according to actual conditions, such as 1%, 7%, etc.

[0084] During the cooling operation of the air conditioner, upon receiving a set wind sense instruction input by the user based on actual needs (a wind sense instruction used to ensure that the maximum actual wind speed of the indoor environment does not exceed the set wind speed threshold, and the maximum actual wind sense index of the indoor environment does not exceed the set wind sense index threshold, such as a no wind sense instruction), the air guide component can be controlled to operate in the target air guide state; the air conditioner operating conditions (such as whether the indoor environment temperature reaches the target temperature, etc.) or the scene parameters in its action space (such as whether there is a human body within a range less than a set distance, whether the temperature of the area where the human body is located reaches the target temperature, etc.) can also be monitored in real time or at set intervals during the cooling operation. When the monitored results meet the set conditions (such as the indoor environment temperature reaches the target temperature, there is a human body within a range less than a set distance, or the temperature of the area where the human body is located reaches the target temperature, etc.), the air guide component is controlled to operate in the target air guide state. Among them, during the cooling operation of the air conditioner, if the set wind sense instruction input by the user is not received or the monitored result does not meet the set conditions, the air guide component can be controlled to open the air outlet, that is, the air guide component can be controlled to operate in the second air guide state mentioned in the above embodiment, and the air after heat exchange in the indoor heat exchanger can be directly sent into the indoor environment under the drive of the fan.

[0085] The air guide assembly is rotatably mounted on the housing, and the first air dispersing plate and the second air dispersing plate are connected to form an air guide cavity. Based on this, the air guide assembly can be controlled to rotate to the first air guide position, so that the first air dispersing plate is exposed at the air outlet, and the second air dispersing plate is located inside the housing, so that the air guide assembly reaches the target air guide state. The first air dispersing plate and / or the second air dispersing plate are provided with air guide blades. In the target air guide state, the air guide blades are in a swinging state, which helps to further ensure that the indoor environment can accurately reach the target state. In addition, in other embodiments, when the air guide assembly is in the target air guide state, the air guide blades can also be in a stopped state according to actual needs.

[0086] While the air guide assembly is dispersing air in its target air guide state, the indoor heat exchanger temperature and indoor dew point temperature can be obtained in real time or at set intervals. In this embodiment, the indoor heat exchanger temperature is detected by a temperature sensor located on the indoor heat exchanger coil; the indoor dew point temperature can be calculated based on the indoor ambient temperature and humidity detected by a detection module located at the air conditioner's return air outlet or indoor environment. In other embodiments, the indoor dew point temperature can also be obtained by obtaining data from an environmental parameter sensor located external to the air conditioner.

[0087] Step S20, determining the target frequency of the compressor according to the indoor heat exchanger temperature and the indoor dew point temperature;

[0088] The target frequency here specifically refers to the target value of the compressor's desired operating frequency. The target frequency is less than the set frequency. The set frequency is the maximum frequency allowed for the compressor to operate without condensation at the air outlet when the air guide assembly is operating in the target air guide state. The set frequency is less than the compressor's rated maximum frequency and greater than the compressor's rated minimum frequency. Therefore, the target frequency is one or more frequency values ​​between the compressor's rated minimum frequency and the set frequency.

[0089] Different indoor heat exchanger temperatures and different indoor dew point temperatures correspond to target frequencies of different values. Based on the target state that the indoor environment needs to reach when the air guide component operates in the target air guide state (the maximum value of the actual wind speed of the indoor environment will not exceed the set wind speed threshold, and the maximum value of the actual wind feeling index of the indoor environment will not exceed the set wind feeling index threshold), the correspondence between the indoor heat exchanger temperature, the indoor dew point temperature and the target frequency can be established in advance. The correspondence can be in the form of a calculation relationship, a mapping relationship and / or an algorithm model. In the correspondence, all target frequencies cooperate with the target air guide state of the air guide component to enable the indoor environment to reach the target state. Based on this correspondence, the target frequency of the compressor corresponding to the current indoor heat exchanger temperature and indoor dew point temperature can be determined. For example, when the corresponding relationship is a preset formula that characterizes the quantitative relationship between the indoor heat exchanger temperature, the indoor dew point temperature and the target frequency, the current indoor heat exchanger temperature and the indoor dew point temperature can be substituted into the preset formula for calculation, and the calculated result is used as the target frequency; when the corresponding relationship is a mapping table that characterizes the mapping relationship between the indoor heat exchanger temperature, the indoor dew point temperature and the target frequency, the mapping table can be queried through the indoor heat exchanger temperature and the indoor dew point temperature, and the matching result in the mapping table is used as the target frequency required for the compressor to operate.

[0090] Step S30: controlling the compressor to operate at the target frequency.

[0091] When the compressor operates at the target frequency, the maximum actual wind speed in the indoor environment will not exceed the set wind speed threshold, and the maximum actual wind feeling index in the indoor environment will not exceed the set wind feeling index threshold.

[0092] An embodiment of the present invention proposes a control method for an air conditioner. During the cooling operation of the air conditioner, the method disperses the air flow blown out from the air outlet in the shell through a double-layer air dispersing plate, so that the air outlet of the air conditioner can ensure that the indoor environmental wind speed and wind sensation index are both lower than the corresponding threshold value, so as to ensure the wind comfort of users in the environment. On this basis, the operating frequency of the compressor is limited in combination with the indoor heat exchanger temperature and the indoor dew point temperature, so as to ensure that the cold energy carried by the air blown to the air outlet after heat exchange in the indoor heat exchanger is dissipated into the room without causing condensation at the air outlet, which can meet the user's wind comfort while preventing condensation from occurring in the air conditioner.

[0093] Furthermore, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to Figure 6 , the step S20 includes:

[0094] Step S21, determining the temperature difference between the indoor heat exchanger temperature and the indoor dew point temperature;

[0095] The temperature difference here specifically refers to the absolute value of the difference between the temperature of the indoor heat exchanger and the indoor dew point temperature.

[0096] Step S22: determining the target frequency according to the temperature difference.

[0097] Different temperature differences correspond to different target frequencies. In this embodiment, the target frequency decreases as the temperature difference increases. A larger temperature difference increases the target frequency; a smaller temperature difference decreases the target frequency. Specifically, the target frequency may decrease linearly or exponentially as the temperature difference increases.

[0098] The corresponding relationship between the temperature difference value and the target frequency can be preset, and can be a quantitative relationship, a mapping relationship, etc. Based on the corresponding relationship, the target frequency corresponding to the current temperature difference value can be determined.

[0099] Specifically, in this embodiment, when the temperature difference value is greater than the set temperature difference threshold, the minimum frequency allowed for the cooling operation of the air conditioner is determined to be the target frequency; when the temperature difference value is less than or equal to the set temperature difference threshold, the frequency correction value corresponding to the temperature difference value is determined, and the minimum frequency is corrected according to the frequency correction value to obtain the target frequency.

[0100] The set temperature difference threshold is specifically a critical temperature difference value for distinguishing whether condensation has begun at the air outlet. When the temperature difference value is less than or equal to the set temperature difference threshold, it indicates that there may be a risk of condensation at the air outlet but condensation has not begun. At this time, the compressor can operate at a frequency greater than the minimum cooling frequency; when the temperature difference value is greater than the set temperature difference threshold, it indicates that condensation has begun at the air outlet. At this time, the compressor needs to operate at the minimum cooling frequency to ensure that the condensation at the air outlet does not further deteriorate or stop condensing. The minimum frequency here is specifically the rated minimum frequency of the compressor, specifically a frequency value determined according to the performance of the compressor itself. The frequency correction value can be a frequency correction coefficient or a frequency correction amplitude. Specifically, the sum of the minimum frequency and the frequency correction amplitude can be used as the target frequency, or the product of the minimum frequency and the frequency correction coefficient can be used as the target frequency.

[0101] In this embodiment, the temperature difference between the indoor dew point temperature and the temperature of the indoor heat exchanger can represent the size of the condensation risk at the air outlet. The greater the temperature difference, the greater the risk, and the smaller the temperature difference, the smaller the risk. Based on this, the target frequency of the compressor operating in a comfortable wind state is determined by the temperature difference value, which can ensure that the determined target frequency matches the condensation risk situation at the air outlet, ensuring that the determined target frequency ensures that no condensation occurs at the air outlet and the frequency can be as large as possible to meet the thermal comfort of the indoor environment.

[0102] Further, in this embodiment, after step S10, the method further includes: when the indoor dew point temperature is less than or equal to the indoor heat exchanger temperature, determining the target frequency according to the indoor ambient temperature; when the indoor dew point temperature is greater than the indoor heat exchanger temperature, performing step S21.

[0103] Among them, when the indoor dew point temperature is less than or equal to the indoor heat exchanger temperature, it indicates that there is no risk of condensation at the current air outlet. Based on this, the operating frequency of the compressor can be determined based on the indoor ambient temperature. Specifically, the target frequency of the compressor operation is determined by the temperature difference between the indoor ambient temperature and the set temperature. The greater the temperature difference, the greater the target frequency; the smaller the temperature difference, the smaller the target frequency. During this process, the target frequency can take any frequency value between the above-mentioned minimum frequency and the maximum frequency allowed for the compressor to operate. When there is no risk of condensation at the air outlet, regulating the operating frequency of the compressor in combination with the indoor ambient temperature can ensure that there is no condensation at the air outlet of the air conditioner. The cooling capacity output from the air outlet of the air conditioner can meet the indoor thermal comfort requirements, effectively balancing the anti-condensation of the air conditioner and the user's thermal comfort.

[0104] When the indoor dew point temperature is greater than the indoor heat exchanger temperature, it indicates that there is a risk of condensation at the current air outlet. At this time, restricting the operating frequency of the compressor in combination with the indoor dew point temperature and the indoor heat exchanger temperature can ensure that the cooling capacity output by the air conditioner is not too large, effectively preventing condensation at the air outlet of the air conditioner. <000023�>

[0105] In a specific application of this embodiment, define the indoor dew point temperature as TL, define the indoor heat exchanger temperature as T2, define the indoor ambient temperature as T1, define the minimum frequency allowed for refrigeration operation as Fmin, define the target frequency as F, and define T0 as the set temperature of the air conditioner. Then, the frequency of the compressor is controlled according to the following rules: <𝟘𝟘𝟘𝟘𝟚𝟛𝟟>

[0106] If TL ≤ T2, then F = F0 * (T1 - T0) / M;

[0107] If 0 < TL - T2 ≤ 3, then F = Fmin + 20Hz;

[0108] If 3 < TL - T2 ≤ 8, then F = Fmin + 10Hz; <000024⒊>

[0109] If 8 < TL - T2, then F = Fmin.

[0110] Further, based on the above embodiment, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to Figure 7 , a swirl module is provided on the first air deflector and / or the second air deflector, and the swirl module is used to disperse the passing air flow and blow it out around the air outlet when rotating. The step S22 includes:

[0111] Step S221, obtaining the rotation speed of the swirl module;

[0112] Here, the rotation speed specifically refers to the rotation speed of the swirl module when it rotates with its axis as the rotation center. The rotation speed of the swirl module can be specifically determined by obtaining the operating parameters of its driving components.

[0113] Step S222, determining a target corresponding relationship corresponding to the rotational speed; the target corresponding relationship is a corresponding relationship between the temperature difference value and the target frequency;

[0114] More than one correspondence can be pre-set between the temperature difference and the target frequency. In different correspondences, the same temperature difference corresponds to different target frequencies. In more than one correspondence, different speeds can be associated with different relationships. The higher the speed, the higher the target frequency corresponding to the temperature difference in the corresponding target correspondence. Based on this, the correspondence associated with the current speed can be obtained as the target correspondence.

[0115] Specifically, the rotational speed of the swirl module can be pre-divided into more than one interval. Within the more than one interval, any two adjacent intervals can be defined as a first rotational speed interval and a second rotational speed interval. The rotational speed within the first rotational speed interval is less than the rotational speed within the second rotational speed interval. The correspondence between the target frequency and the temperature difference corresponding to the first rotational speed interval is a first correspondence, and the correspondence between the target frequency and the temperature difference corresponding to the second rotational speed interval is a second correspondence. The target frequency corresponding to the temperature difference in the first correspondence is a first frequency, and the target frequency corresponding to the temperature difference in the second correspondence is a second frequency, with the first frequency being less than the second frequency.

[0116] Step S223: determining the target frequency corresponding to the temperature difference based on the target corresponding relationship.

[0117] In this embodiment, due to the different rotation speeds of the swirl module, its wind dispersion effect is different and its impact on the air volume out of the air outlet is also different. Therefore, the correspondence between the temperature difference between the current indoor dew point temperature and the indoor heat exchanger temperature and the compressor operating frequency is determined in combination with the rotation speed of the swirl module, which can further improve the accuracy of the determined target frequency and ensure that condensation will not occur at the air outlet when the compressor operates at the determined target frequency.

[0118] Furthermore, in this embodiment, the swirl module includes a first rotor and a second rotor arranged in opposition, the first rotor including a plurality of first rotor blades spaced circumferentially, and the second rotor including a plurality of second rotor blades spaced circumferentially. The step of determining the target correspondence corresponding to the rotational speed includes: obtaining relative position information between the first rotor blade and the second rotor blade; the relative position information includes information on whether the first rotor blade and the second rotor blade are aligned; and determining the target correspondence corresponding to the rotational speed based on the relative position information. Specifically, the relative position information includes first position information and second position information, the first position information being information on the alignment of the first rotor blade and the second rotor blade, and the second position information being information on the alignment of the first rotor blade and the second rotor blade. The ventilation volume of the swirl module corresponding to the first position information is greater than the ventilation volume of the swirl module corresponding to the second position information. The wind dissipation effect of the swirl module corresponding to the first position information is less than the wind dissipation effect of the swirl module corresponding to the second position information. If the relative position information between the second rotor blade and the first rotor blade is different, the target correspondence associated with the rotational speed will be different.

[0119] Specifically, when the relative position information is the first position information, the target correspondence relationship corresponding to the rotational speed is the third correspondence relationship. When the relative position information is the second position information, the target correspondence relationship corresponding to the rotational speed is the fourth correspondence relationship. The target frequency corresponding to the temperature difference value in the third correspondence relationship is the third frequency, and the target frequency corresponding to the temperature difference value in the fourth correspondence relationship is the fourth frequency. The third frequency is greater than the fourth frequency.

[0120] In this embodiment, the target correspondence corresponding to the rotational speed is determined in combination with the relative position information between the first rotor blade and the second rotor blade, thereby further improving the accuracy of the target frequency subsequently determined based on the target correspondence, and ensuring that when the air guide component operates in the target air guide state, condensation will not form on the air outlet of the air guide component.

[0121] Among them, when the above-mentioned step S22 includes a process of correcting the minimum frequency according to the frequency correction value corresponding to the temperature difference value to obtain the target frequency when the temperature difference value is less than or equal to the set temperature difference threshold, the target correspondence relationship obtained in this embodiment in combination with the rotation speed of the swirl module and / or the relative position information of the rotor blades can be used to determine the frequency correction value corresponding to the temperature difference value.

[0122] Furthermore, based on any of the above embodiments, another embodiment of the control method of the air conditioner of the present application is proposed. In this embodiment, referring to Figure 8 , it is defined that when the air conditioner is in cooling operation, controlling the air guide component to operate in a target air guide state is step S101, and after step S101, it also includes:

[0123] Step S11, obtaining the indoor ambient temperature;

[0124] The specific indoor ambient temperature can be detected by the temperature sensor installed at the return air vent.

[0125] Step S12, determining whether the air conditioner meets the start-up conditions for anti-condensation operation according to the indoor ambient temperature and the set temperature of the air conditioner;

[0126] When it is determined that the air conditioner does not meet the start-up conditions for anti-condensation operation, step S13 is executed; when it is determined that the air conditioner meets the start-up conditions for anti-condensation operation, step S14 is executed.

[0127] The startup conditions here specifically refer to the conditions that the indoor ambient temperature and set temperature need to be met when the anti-condensation operation is turned on during the pre-set air conditioning cooling operation, and can be specifically set according to the user's comfort needs.

[0128] Specifically, in this embodiment, the temperature deviation between the indoor ambient temperature and the set temperature of the air conditioner is determined; when the temperature deviation is greater than the set temperature difference, it is determined that the air conditioner has not met the startup condition; when the temperature deviation is less than or equal to the set temperature difference, it is determined that the air conditioner has met the startup condition. The set temperature difference is set specifically based on the user's comfort needs. The temperature deviation is specifically the absolute value of the difference between the indoor ambient temperature and the set temperature. If the temperature deviation is greater than the set temperature difference, it indicates that the current indoor ambient temperature deviates significantly from the user's comfort temperature. Therefore, the anti-condensation function is not activated, and the compressor is controlled to operate at a higher frequency to ensure that when the air guide component operates in the target air guide state, the cooling capacity output by the air conditioner can effectively meet the thermal comfort of the indoor user. If the temperature deviation is less than or equal to the set temperature difference, it indicates that the current indoor ambient temperature deviates slightly from the user's comfort temperature. In this case, the anti-condensation function is activated, and the operating frequency of the compressor is limited in combination with the heat exchanger temperature and dew point temperature, thereby ensuring that the air conditioner can meet the user's thermal comfort needs while avoiding condensation at the air outlet.

[0129] In another embodiment, the ratio or product between the indoor ambient temperature and the set temperature may be determined, and whether the air conditioner meets the start-up conditions for the anti-condensation control may be determined based on the determined ratio or product.

[0130] Step S13, controlling the compressor to operate at a frequency greater than a set frequency;

[0131] Specifically, the compressor may be operated at a rated maximum frequency.

[0132] Step S14, obtaining the indoor heat exchanger temperature and the indoor dew point temperature, based on the target frequency determined in step S14 and subsequent steps being less than the set frequency.

[0133] In this embodiment, when the air conditioner meets the anti-condensation operating conditions, the compressor operating frequency is limited by combining the heat exchanger temperature and dew point temperature, effectively preventing condensation. When the air conditioner does not meet the anti-condensation operating conditions, the air conditioner operates at a higher frequency, effectively ensuring thermal comfort for indoor users. The indoor ambient temperature and set temperature reflect the user's comfort level, and these two factors serve as the activation conditions for anti-condensation operation. This ensures that the air delivery from the air conditioner in a comfortable wind speed state effectively balances anti-condensation and thermal comfort for indoor users.

[0134] In addition, an embodiment of the present invention further proposes a computer-readable storage medium, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, the relevant steps of any embodiment of the above air conditioner control method are implemented.
