Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] With the development of economy and technology, air conditioners are being used more and more widely, and their performance is constantly being optimized. Currently, many air conditioners have comfortable airflow modes such as no wind, gentle wind, and weak wind. When these comfortable airflow modes are running, the temperature at the air outlet can easily deviate significantly from the ambient temperature. In environments with high humidity, condensation can easily form on the structural components of the air outlet.

[0003] Currently, anti-condensation in comfort mode is generally achieved by limiting the control parameters related to the air outlet temperature of the air conditioner, so as to prevent the air outlet temperature from deviating too much from the room temperature. For example, when the air conditioner is in cooling mode, the air outlet temperature needs to be limited to prevent it from being too low. However, this will lead to a decrease in the heat exchange effect of the air conditioner. Summary of the Invention

[0015] The air guide plate is controlled to block the air outlet, and the indoor fan is controlled to run at a second speed, which is less than the first speed.

[0016] Optionally, after the step of controlling the dehumidification operation of the air conditioner, the method further includes:

[0017] If the air conditioner has a risk of condensation, then obtain the duration of the air conditioner's dehumidification operation.

[0018] When the duration is greater than or equal to the preset duration, the operating frequency of the compressor is reduced, or the operating speed of the indoor fan is increased.

[0019] Optionally, after or simultaneously with the step of reducing the operating frequency of the compressor or increasing the operating speed of the indoor fan, the method further includes:

[0020] Output a prompt message, which is used to improve the airtightness of the space where the air conditioner operates.

[0021] Optionally, the step of reducing the operating frequency of the compressor or increasing the operating speed of the indoor fan when the duration is greater than or equal to a preset duration includes:

[0022] When the duration is greater than or equal to the preset duration, the indoor heat exchanger temperature is obtained;

[0023] When the temperature of the indoor heat exchanger is less than or equal to a preset temperature threshold, the operating frequency of the compressor is reduced, or the operating speed of the indoor fan is increased.

[0024] Optionally, after the step of obtaining the first ambient humidity of the space where the air conditioner operates, the method further includes:

[0025] When the first ambient humidity is less than the first set humidity threshold, the air conditioner is controlled to start the preset wind-feeling mode.

[0028] The risk of condensation in the air conditioner is determined based on the second ambient humidity and the second set humidity threshold, wherein:

[0029] When the second ambient humidity is less than or equal to the second set humidity threshold, it is determined that the air conditioner has no risk of condensation.

[0030] When the second ambient humidity is greater than the second set humidity threshold, it is determined that the air conditioner has a risk of condensation.

[0031] Wherein, the second set humidity threshold is less than or equal to the first set humidity threshold;

[0032] Optionally, during the dehumidification operation of the air conditioner, the air guide plate is controlled to block the air outlet.

[0036] In addition, to achieve the above objectives, this application also proposes a computer-readable storage medium storing a control program for an air conditioner, which, when executed by a processor, implements the steps of the control method for the air conditioner as described in any of the preceding claims.

[0037] This invention proposes a control method for an air conditioner based on an air conditioner with an air guide plate having diffuser holes at the air outlet. The diffuser effect is achieved by the air guide plate having multiple diffuser holes and a swirling module on the air guide plate. Based on this, when the method receives a start command for a preset wind-feeling mode, that is, when the preset wind-feeling mode needs to be activated, if the ambient humidity is too high, the method first controls the air conditioner to dehumidify to reduce the indoor humidity. When the dehumidification operation reaches a point where there is no risk of condensation, it indicates that the risk of condensation on the air outlet structure of the air conditioner is low. At this time, the method controls the air conditioner to activate the preset wind-feeling mode. In the preset wind-feeling mode, the air guide plate blocks the air outlet to disperse the airflow blown out of the air outlet, which can achieve a lower wind speed and wind feel index in the air conditioner's operating space to meet the user's wind comfort. Furthermore, since the risk of condensation is low during this process, there is no need to limit the air outlet temperature of the air conditioner. Even if the air conditioner operates at a lower air outlet temperature, condensation will not occur, thereby preventing condensation on the air conditioner and improving the heat exchange effect in the air conditioner's comfortable wind-feeling mode.

[0046] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0048] The main solution of this invention is: an air conditioner with an air guide plate having air dissipation holes at the air outlet. The method includes: receiving a start command for a preset wind-feeling mode and obtaining a first ambient humidity of the space where the air conditioner operates; when the first ambient humidity is greater than or equal to a first set humidity threshold, controlling the air conditioner to dehumidify; when the air conditioner dehumidifies until there is no risk of condensation, controlling the air conditioner to start the preset wind-feeling mode; wherein, in the preset wind-feeling mode, the air guide plate blocks the air outlet, the wind speed in the space where the air conditioner operates is less than or equal to a set wind speed threshold, and the wind-feeling index is less than or equal to a set index threshold.

[0049] In existing technologies, anti-condensation in comfort mode is generally achieved by limiting control parameters related to the air outlet temperature of the air conditioner to prevent the deviation between the air outlet temperature and the room temperature from being too large. For example, when the air conditioner is in cooling mode, the air outlet temperature needs to be limited to prevent it from being too low. However, this will lead to a decrease in the heat exchange effect of the air conditioner and affect the user's comfort.

[0050] The present invention provides the above-mentioned solution, which aims to prevent condensation in air conditioners while improving the heat exchange effect in the comfort mode of air conditioners.

[0051] This invention provides an air conditioner. The air conditioner can specifically be a floor-standing air conditioner, a cabinet air conditioner, a window air conditioner, etc.

[0052] In this embodiment of the invention, reference is made to Figure 1 and Figure 2 The air conditioner is a floor-standing unit. Specifically, the air conditioner includes a housing 1, an indoor heat exchanger 7, and an indoor fan 2. The housing 1 has an air inlet and an air outlet, with the air outlet extending along the height of the unit. The number of air outlets can be one or more depending on actual needs. In this embodiment, there are two air outlets, spaced apart laterally along the side of the air conditioner.

[0053] The housing 1 may be provided with an air duct connecting the air inlet and the air outlet. The indoor fan 2 and the indoor heat exchanger 7 are both located in the air duct. When the indoor fan 2 is running, the air in the indoor environment can enter the air duct from the air inlet and exchange heat through the indoor heat exchanger 7. The airflow after heat exchange through the indoor heat exchanger 7 is sent into the indoor environment from the air outlet.

[0054] Furthermore, refer to Figure 1 and Figure 2The air outlet may be equipped 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 inside the housing 1 can be sent into the indoor environment from the air outlet; when the switch door 01 is in the closed position, the airflow inside the housing 1 cannot be sent into the indoor environment from the air outlet.

[0055] Reference Figure 2 The air conditioner also includes an air guide plate 3, which is disposed on the housing 1 and corresponding to the air outlet. Specifically, the air guide plate 3 includes a diffuser plate with multiple diffuser holes. Furthermore, the diffuser plate is provided with a swirl module. The swirl module is used to disperse the airflow passing through it and blow it out from all sides when rotated.

[0056] The air diffuser includes a first air diffuser 31 and a second air diffuser 32. Both the first air diffuser 31 and the second air diffuser 32 are provided with multiple air dispersion holes, which disperse the airflow passing through them. The air dispersion holes can be grille holes, micropores, or mesh holes, etc. Both the first air diffuser 31 and the second air diffuser 32 are rotatably connected to the housing 1 to open or block the air outlet.

[0057] The relative positions of the first air diffuser 31 and the second air diffuser 32 are fixed. If the position of the first air diffuser 31 changes, the second air diffuser 32 will change accordingly. Specifically, the first air diffuser 31 and the second air diffuser 32 can be connected to the housing 1 via the same rotating shaft, which extends along the height direction of the housing 1. Because the first air diffuser 31 and the second air diffuser 32 rotate at different positions, their positions relative to the air outlet are different, resulting in different air guiding states of the air guide plate 3.

[0058] In this embodiment, the air guide plate 3 has a first air guiding state and a second air guiding state, and the air guide plate 3 can switch between the first air guiding state and the second air guiding state by rotation. The air outlet velocity corresponding to the first air guiding state is less than or equal to a set air velocity, and the air outlet velocity corresponding to the second air guiding state is greater than the set air velocity.

[0059] In the first airflow guiding state, the first air diffuser 31 and the second air diffuser 32 are in the first airflow guiding position and cooperate to block the air outlet. Specifically, the first airflow guiding position is that the first air diffuser 31 blocks the air outlet, and the second air diffuser 32 is located inside the housing 1 in a windproof state. At this time, the second air diffuser 32 blocks the airflow blowing from the housing 1 toward the first air diffuser 31. When the first air diffuser 31 completely blocks the air outlet, the edge of the first air diffuser 31 closes the edge of the air outlet, and all airflow is sent into the room through the first air diffuser 31. Based on this, the airflow that needs to be sent into the room from the air outlet after heat exchange by the indoor heat exchanger 7 is first dispersed by the air diffuser holes on the second air diffuser 32, and then further dispersed by the air diffuser holes on the first air diffuser 31 before being sent into the room. At this time, the air conditioner has a small air volume and wind speed, and the user feels a weak wind.

[0060] In the second air-guiding state, the first diffuser plate 31 and the second diffuser plate 32 are in the second air-guiding position and the air outlet is open. Specifically, the second air-guiding position is such that both the first diffuser plate 31 and the second diffuser plate 32 are located inside the housing 1, the second diffuser plate 32 is spaced apart from the edge of the air outlet, and the first diffuser plate 31 is located inside the second diffuser plate 32. At this time, the first diffuser plate 31 and the second diffuser plate 32 cooperate to open the air outlet, and the airflow inside the housing 1 is sent into the indoor environment through the gap between the edge of the second diffuser plate 32 and the air outlet. It should be noted that the distance between the first diffuser plate 31 and the air outlet is greater than the distance between the second diffuser plate 32 and the air outlet. Based on this, a small portion of the airflow that needs to be sent into the room from the air outlet after heat exchange by the indoor heat exchanger 7 can be diffused by the two diffuser plates before being sent into the room, while most of it is directly sent into the room through the gap between the second diffuser plate 32 and the air outlet. At this time, the air conditioner has a large air volume and speed, and the user experiences a strong airflow.

[0061] The first air diffuser 31 and the second air diffuser 32 can be configured as flat plates or curved surfaces with arc surfaces, depending on actual needs. Specifically, in this embodiment, the two oppositely arranged surfaces of the first air diffuser 31 are defined as air guiding surfaces. The air guiding surface of the first air diffuser 31 is an arc surface that bulges away from the second air diffuser 32, which helps to reduce the feeling of wind while increasing the air outlet area.

[0062] Specifically, in one embodiment of the air conditioner, the edge of the first diffuser 31 can be connected to the edge of the second diffuser 32 to form a guide cavity. Based on this, when the first diffuser 31 blocks the air outlet, the airflow after being dispersed by the second diffuser 32 can be fully gathered in the guide cavity and then sent into the room from the first diffuser 31. This ensures that the two diffusers work together to reduce the air velocity at the air outlet while ensuring sufficient cooling output at the air outlet through the converging effect.

[0063] Furthermore, refer to Figure 3In addition to the air dissipation holes, the second air diffuser 32 may also have ventilation holes. The diameter of the ventilation holes is larger than that of the air dissipation holes. Specifically, the ventilation holes may contain swirl modules, grilles, or mesh, or they may be left empty. In this embodiment, there are multiple ventilation holes, and each ventilation hole is equipped with a swirl module. The swirl module is used to disperse the airflow passing through it and blow it out from all sides when it rotates.

[0064] In this embodiment, the air guide plate may further include a swirl module 4. The swirl module 4 may be disposed on the first diffuser plate 31 and / or the second diffuser plate 32, between the first diffuser plate 31 and the second diffuser plate 32, or on the side of the first diffuser plate 31 away from the second diffuser plate 32, depending on actual needs. The swirl module 4 includes a turntable, which may be provided with swirl blades, a grille, or a mesh. When the swirl module 4 rotates, it can disperse the airflow blowing towards the air outlet from the housing 1 or the airflow flowing through the air outlet to the surroundings, thereby further reducing the airflow velocity at the air outlet; and when the swirl module 4 stops rotating, the airflow can be blown out from between the swirl blades of the swirl module 4. Wherein, the airflow velocity at the air outlet when the swirl module 4 stops rotating is greater than the airflow velocity at the air outlet when the swirl module 4 rotates.

[0065] Specifically, in one embodiment of the air conditioner, the swirl module 4 includes a first impeller and a second impeller arranged opposite to each other. The first impeller includes a plurality of first swirl blades spaced apart circumferentially, and the second impeller includes a plurality of second swirl blades spaced apart circumferentially. Specifically, the first impeller is fixed to the ventilation hole, and the second impeller is rotatable relative to the first impeller. Specifically, the first impeller may be provided with a limiting member that cooperates with the second impeller. When the first impeller rotates, the second impeller rotates following the first impeller under the limiting action of the limiting member. During the synchronous rotation of the first and second impellers, the first and second impellers have a first relative position and a second relative position. The first relative position is the position where the first and second swirl blades are aligned, and the second relative position is the position where the first and second swirl blades are misaligned. The ventilation area of ​​the swirl module corresponding to the first relative position is larger than the ventilation area of ​​the swirl module corresponding to the second relative position, and the air dispersion effect of the swirl module corresponding to the second relative position is better than the air dispersion effect of the swirl module corresponding to the first relative position.

[0066] Furthermore, in one embodiment of the air conditioner, referring to Figure 3The second air diffuser 32 may also be provided with a connecting rod and louvers 5 connected to the connecting rod on the side opposite to the first air diffuser 31. The louvers 5 include multiple guide vanes connected by the connecting rod. Based on this, in the second air guiding state, the air outlet direction can be adjusted by moving the connecting rod in the up-down or left-right direction, causing the louvers 5 to swing back and forth or guide the air at a fixed angle. In the first air guiding state, the air outlet volume can be adjusted when the louvers 5 located in the air duct are set at different angles with the connecting rod. Specifically, when the louvers 5 are parallel to the airflow direction in the air duct, the air outlet volume is greater than when the louvers 5 are in other positions. Each guide vane can be set with a corresponding swirl module 4.

[0067] Furthermore, in one embodiment of the air conditioner, the air conditioner also includes a detection module 6, which can be located in the external environment of the air conditioner or on the air conditioner (e.g., at the air return vent). The detection module 6 can be used to detect the humidity and / or temperature of the space in which the air conditioner operates.

[0068] This invention also proposes a control device for an air conditioner, which is used to control the air conditioner. The control device can be built into the air conditioner or installed independently outside the air conditioner according to actual needs.

[0069] In this embodiment of the invention, reference is made to Figure 4 The control device for the air conditioner includes a processor 1001 (e.g., a CPU), a memory 1002, and a timer 1003. The processor 1001, memory 1002, and timer 1003 can be connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0070] Specifically, the indoor fan 2, air guide plate 3, swirl module 4, louvers 5, detection module 6, and compressor 9 in the air conditioner are all connected to the control device in this embodiment.

[0071] Those skilled in the art will understand that Figure 4 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0072] like Figure 4 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 4 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0073] This invention also provides a control method for an air conditioner, which is used to control the air conditioner described above.

[0074] Reference Figure 5 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0075] Step S10: Receive the start command of the preset wind sensing mode and obtain the first ambient humidity of the space where the air conditioner is located;

[0076] When the preset fan mode activation command is received, it indicates that the air conditioner needs to activate the preset fan mode. The activation command for the preset fan mode can be entered by the user or generated by the air conditioner when the user's status or the indoor environment meets preset conditions.

[0077] The first ambient humidity here can be a parameter characterizing the ambient humidity, such as absolute humidity, relative humidity, or moisture content. When the first ambient humidity is relative humidity, it can be obtained by directly reading the detection data from a humidity detection module located in the air conditioner's operating space (such as the air conditioner's return air vent). When the first ambient humidity is moisture content, it can be obtained by acquiring humidity detection data collected by a humidity detection module in the air conditioner's operating space and temperature detection data collected by a temperature detection module in the air conditioner's operating space, and then combining the humidity detection data and temperature detection data to calculate the moisture content of the air conditioner's operating space as the first ambient humidity.

[0078] Step S20: When the first ambient humidity is greater than or equal to the first set humidity threshold, control the air conditioner to dehumidify.

[0079] The first set humidity threshold is specifically a critical value used to distinguish whether there is a risk of condensation on the structural components of the air outlet of the air conditioner. If the first ambient humidity is greater than or equal to the first set humidity threshold, it indicates that there is a risk of condensation on the structural components of the air outlet; if the first ambient humidity is less than the first set humidity threshold, it indicates that there is no risk of condensation on the structural components of the air outlet. The first set humidity threshold is a pre-set parameter. In this embodiment, the value range of the first set humidity threshold is 65%-75%, for example, 70%. In other embodiments, it can be set to other values ​​according to actual conditions.

[0080] Dehumidification operation of an air conditioner is specifically an operating mode aimed at reducing the effective area of ​​the air conditioner. During dehumidification, the air conditioner is in cooling mode. Moisture in the indoor air condenses on the indoor evaporator as it passes through, thus reducing the indoor humidity. The parameters for dehumidification operation are not specifically limited, as long as the dehumidification effect is achieved. For example, the indoor humidity can be reduced by controlling the compressor frequency, the opening of the electronic expansion valve, and / or the indoor fan speed during cooling mode.

[0081] During dehumidification operation of the air conditioner, the air guide plate can operate in either a first air guiding state or a second air guiding state. In this embodiment, during the dehumidification operation of the air conditioner, the air guide plate is controlled to block the air outlet, thereby reducing the wind speed and wind feel index in the air conditioner's operating space through the air dispersion effect of the air guide plate while dehumidifying, thus ensuring that the air conditioner reduces ambient humidity while meeting the user's wind comfort requirements.

[0082] Step S30: When the air conditioner dehumidifies until there is no risk of condensation, control the air conditioner to start the preset airflow mode;

[0083] In the preset wind-feeling mode, the air guide plate blocks the air outlet, the wind speed in the air conditioner's operating space is less than or equal to a set wind speed threshold, and the wind-feeling index is less than or equal to a set index threshold.

[0084] The wind speed threshold and / or wind feel index set here can be user-defined parameters or system default settings. The wind feel index includes the unsteady-state wind feel index (USDR value) and / or the steady-state wind feel index (DR value). The unsteady-state wind feel index refers to the percentage of people dissatisfied due to airflow carrying away body heat when the air conditioner's operating space is not in a thermally stable state. The steady-state wind feel index refers to the percentage of people dissatisfied due to airflow carrying away body heat when the air conditioner's operating space is in a thermally stable state. In this embodiment, the wind speed threshold is set within the range of [0.2 m / s, 0.4 m / s], for example, 0.3 m / s. In other embodiments, the wind speed threshold can be set to other values, such as 0.6 m / s, 0.1 m / s, etc. In this embodiment, the unsteady-state wind feel index is set within the range of [7%, 12%], for example, 10%. In other embodiments, the unsteady-state wind feel index can be set to other values, such as 13%, 15%, etc. In this embodiment, the unsteady-state airflow sensation index ranges from [2%, 6%], for example, 5%. In other embodiments, the unsteady-state airflow sensation index can also be set to other values, such as 1%, 7%, etc., depending on the actual situation.

[0085] Whether an air conditioner poses a condensation risk can be determined by obtaining the actual operating parameters of the air conditioner (e.g., the duration of dehumidification operation) or the environmental parameters of the space in which the air conditioner operates (e.g., ambient temperature and / or humidity). The operating parameters of the air conditioner or the environmental parameters of the space can be preset as target parameters to indicate whether a condensation risk exists. The actual detected operating parameters of the air conditioner or the environmental parameters are then compared with the target parameters to determine whether a condensation risk exists.

[0086] Once the air conditioner has completed its dehumidification process and there is no risk of condensation, it indicates that the air conditioner currently poses no risk of condensation. At this point, the air conditioner can be controlled to activate the preset fan mode and begin comfortable airflow operation to meet the user's airflow comfort requirements. In the preset fan mode, the air conditioner can maintain cooling operation.

[0087] Specifically, before the preset wind-sensing mode is activated, the air guide plate can be controlled to operate in the second air-guiding state described above. When the preset wind-sensing mode is activated, the air guide plate can be controlled to operate in the first air-guiding state described above. Among them, when the air guide plate is operating in the first air-guiding state, that is, in the state of blocking the air outlet, the vortex module on the air guide plate can rotate or stop rotating.

[0088] This invention proposes a control method for an air conditioner. Based on an air conditioner with an air guide plate having diffuser holes at the air outlet, when the method receives a start command for a preset wind-feeling mode (i.e., when the preset wind-feeling mode needs to be activated), if the ambient humidity is too high, the method first controls the air conditioner to dehumidify to reduce indoor humidity. Once the dehumidification operation reaches a point where there is no risk of condensation, indicating a low risk of condensation on the air outlet structure, the method then activates the preset wind-feeling mode. In this mode, the air guide plate blocks the air outlet to disperse the airflow, resulting in lower wind speed and wind feel index within the air conditioner's operating space, thus satisfying the user's wind comfort. Furthermore, due to the low risk of condensation, there is no need to limit the air outlet temperature. Even when operating at a lower air outlet temperature, condensation will not occur, thereby preventing condensation while improving the heat exchange effect in the air conditioner's comfortable wind-feeling mode.

[0089] Furthermore, in this embodiment, when the first ambient humidity is less than a first set humidity threshold, the air conditioner is controlled to activate the preset wind-feeling mode. Specifically, the air guide plate is controlled to block the air outlet. The preset wind-feeling mode can be pre-set with corresponding frequency and speed ranges. Within the frequency range, the frequency is less than the maximum frequency allowed for compressor operation, and within the speed range, the speed is less than the maximum frequency allowed for indoor fan operation. Based on this, the wind speed in the air conditioner's operating space is less than or equal to a set wind speed threshold, and the wind-feeling index is less than or equal to a set index threshold.

[0090] Furthermore, in this embodiment, the air guide plate is equipped with a swirling module. When the swirling module rotates, it disperses the airflow passing through it and blows it outwards. During the dehumidification operation of the air conditioner, the swirling module is controlled to stop rotating. During the operation of the preset airflow mode of the air conditioner, the swirling module is controlled to rotate. The air dispersion effect when the swirling module is not rotating is less than the air dispersion effect when it is rotating, and the airflow volume when the swirling module is not rotating is greater than the airflow volume when it is rotating. Therefore, this helps to improve the dehumidification efficiency of the air conditioner during dehumidification operation, achieving a rapid reduction in ambient humidity. It also helps to further ensure that the wind speed within the air conditioner's operating space is less than a set wind speed threshold and the airflow index is less than a set index threshold, ensuring the user's airflow comfort within the air conditioner's operating space.

[0091] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 6 The steps for controlling the dehumidification operation of the air conditioner include:

[0092] Step S21: Control the air conditioner to operate in cooling mode, wherein the operating frequency of the air conditioner's compressor during cooling operation is a first frequency, and the compressor in the preset fan mode has at least two frequency ranges, with the first frequency located in the largest frequency range among the at least two frequency ranges.

[0093] The minimum threshold value of the maximum frequency range can be preset. The minimum threshold value can be greater than or equal to 80%, 85%, 90%, or 95% of the compressor's maximum frequency in the preset wind mode.

[0094] The first frequency can be a preset frequency, or it can be a frequency determined within the maximum speed range based on indoor environmental conditions (such as temperature and / or humidity) and / or the conditions of the air conditioner's air outlet (such as the temperature of the air outlet).

[0095] Specifically, in this embodiment, the compressor can be controlled to operate at its maximum frequency under a preset fan mode.

[0096] In addition, the step of controlling the dehumidification operation of the air conditioner may also include:

[0097] Step S22: Control the air conditioner to operate in cooling mode. During the cooling operation, the indoor fan speed of the air conditioner is a first speed. In the preset wind-feeling mode, the indoor fan has at least two speed ranges, and the first speed is located in the maximum speed range among the at least two speed ranges.

[0098] The minimum threshold value of the maximum speed range can be preset. The minimum threshold value can be greater than or equal to 80%, 85%, 90%, or 95% of the maximum speed of the indoor fan in the preset wind mode.

[0099] The first speed can be a preset speed, or it can be a speed determined within the maximum speed range based on indoor environmental conditions (such as temperature and / or humidity) and / or the conditions of the air conditioner's air outlet (such as the temperature of the air outlet).

[0100] Specifically, in this embodiment, the indoor fan can be controlled to operate at its maximum speed in a preset airflow mode.

[0101] In the preset fan mode, the dehumidification operation of the air conditioner can be controlled according to one or all of steps S21 and S22.

[0102] Here, the higher the compressor frequency, the lower the temperature of the indoor evaporator in cooling mode, the more moisture in the air can condense on the indoor evaporator, and the higher the speed of the indoor fan, the faster the dehumidification efficiency of the air conditioner. Based on this, the indoor humidity can be reduced rapidly.

[0103] Based on the above steps S21 and / or S22, the step of controlling the air conditioner to start the preset wind-feeling mode in step S30 includes:

[0104] Step S31: Control the air guide plate to block the air outlet and control the compressor to operate at a second frequency, the second frequency being less than or equal to the first frequency;

[0105] The second frequency can be a preset frequency, or it can be determined based on indoor environmental conditions (such as temperature and / or humidity) and / or the conditions of the air conditioner's air outlet (such as the temperature of the air outlet). It can be within the frequency range allowed by the preset wind-sensing mode (such as the at least two frequency ranges mentioned above).

[0106] The second frequency can be a fixed frequency or a variable frequency, but the variable frequency cannot exceed the frequency range allowed in the preset wind mode.

[0107] In the preset fan mode, if there is a risk of condensation in the air conditioner, the compressor is controlled to operate at an anti-condensation frequency, which is less than the maximum frequency range mentioned above.

[0108] Step S32: Control the air guide plate to block the air outlet, and control the indoor fan to run at a second speed, which is less than the first speed.

[0109] The second speed can be a preset speed or a speed determined based on indoor environmental conditions (such as temperature and / or humidity) and / or the conditions of the air conditioner's air outlet (such as the temperature of the air outlet). It can be within the speed range allowed by the preset wind-feeling mode (such as the at least two speed ranges mentioned above).

[0110] The second speed can be a fixed speed or a variable speed, but the variable speed cannot exceed the speed range allowed in the preset wind-feel mode.

[0111] In the preset wind-sensing mode, if there is a risk of condensation on the air conditioner, the indoor fan will be controlled to operate at a speed lower than the maximum speed range mentioned above to prevent condensation.

[0112] Specifically, in the preset fan mode, the air conditioner is in cooling mode.

[0113] In this embodiment, under the air-diffusing effect of the air guide plate, the compressor operation is controlled by the second frequency and the second speed, which helps to ensure that the air outlet temperature of the air conditioner is not too low, while the air outlet speed and wind feel index are not too high, thereby ensuring the cooling effect of the air conditioner and that the air outlet temperature is not too low.

[0114] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 7 After step S20, the method further includes:

[0115] Step S201: If there is a risk of condensation in the air conditioner, then obtain the duration of the dehumidification operation of the air conditioner.

[0116] Step S202: When the duration is greater than or equal to the preset duration, reduce the operating frequency of the compressor or increase the operating speed of the indoor fan.

[0117] The preset duration can be a parameter set by the user or a parameter pre-configured by the system. In this embodiment, the preset duration ranges from [10 min, 40 min], for example, 30 min. In other embodiments, the preset duration can also be set to other values ​​according to actual needs, such as 5 min, 50 min, etc.

[0118] The compressor frequency can be adjusted according to preset frequency adjustment parameters, such as reducing the preset frequency range or reducing it to the preset anti-condensation frequency. The compressor frequency can also be adjusted according to the actual ambient humidity. For example, the deviation between the ambient humidity and the first preset humidity threshold is determined. The larger the deviation, the greater the frequency reduction, thereby effectively reducing the air outlet temperature of the air conditioner to avoid condensation.

[0119] The indoor fan speed can be adjusted according to preset speed adjustment parameters, such as reducing the preset speed range or reducing it to the preset anti-condensation speed. The indoor fan speed can also be adjusted according to the actual ambient humidity. For example, the deviation between the ambient humidity and the first preset humidity threshold is determined. The larger the deviation, the greater the speed reduction, thereby effectively dissipating heat from the air outlet components and preventing the components from getting too cold, thus avoiding condensation in the air conditioner.

[0120] Even when the air conditioner is running for a long time, there is still a risk of dehumidification, indicating that the indoor humidity is difficult to reduce. In this case, the compressor can be operated at a lower frequency or the indoor fan speed can be increased to ensure that condensation does not occur at the air outlet of the air conditioner.

[0121] Furthermore, after or simultaneously with step S202, a prompt message can be output to improve the airtightness of the space where the air conditioner operates. For example, the user can be prompted to close doors and windows. Based on this, the airtightness of the space where the air conditioner is located can be effectively improved, preventing outdoor humidity from entering the room, effectively avoiding condensation on the air conditioner, and also improving the dehumidification efficiency of the air conditioner.

[0122] Step S202 further includes: when the duration is greater than or equal to the preset duration, obtaining the indoor heat exchanger temperature; when the indoor heat exchanger temperature is less than or equal to the preset temperature threshold, reducing the operating frequency of the compressor, or increasing the operating speed of the indoor fan.

[0123] The temperature of the indoor heat exchanger can be obtained by reading the temperature data detected by the temperature sensor installed on the indoor heat exchanger coil.

[0124] The preset temperature threshold is a critical value used to distinguish whether the system has sufficient refrigerant in the indoor heat exchanger. When the indoor heat exchanger temperature is less than or equal to the preset temperature threshold, it indicates that the system has sufficient refrigerant; when the indoor heat exchanger temperature is greater than the preset temperature threshold, it indicates that the system has insufficient refrigerant. Based on this, when there is still a risk of condensation during prolonged dehumidification operation of the air conditioner, comparing the indoor heat exchanger temperature with the preset temperature threshold can determine whether it is caused by insufficient refrigerant. If insufficient refrigerant is ruled out, and it is confirmed that the problem is due to insufficient indoor airtightness, a prompt message will be output while the air conditioner is operating its anti-condensation function, reminding the user to close doors and windows, thereby ensuring the effectiveness of the air conditioner's anti-condensation operation and further ensuring that condensation will not occur.

[0125] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 8 After the step of controlling the dehumidification operation of the air conditioner, the method further includes:

[0126] Step S40: Obtain the second ambient humidity of the space where the air conditioner operates;

[0127] The second ambient humidity here can be a parameter characterizing the ambient humidity, such as absolute humidity, relative humidity, or moisture content. When the second ambient humidity is relative humidity, it can be obtained by directly reading the detection data from a humidity detection module located in the air conditioner's operating space (such as the air conditioner's return air vent). When the second ambient humidity is moisture content, it can be obtained by acquiring humidity detection data collected by a humidity detection module in the air conditioner's operating space and temperature detection data collected by a temperature detection module in the air conditioner's operating space, and then combining the humidity detection data and temperature detection data to calculate the moisture content of the air conditioner's operating space as the second ambient humidity.

[0128] Specifically, the risk of condensation in the air conditioner is determined based on the second ambient humidity and the second set humidity threshold.

[0129] Step S50: Determine whether the second ambient humidity is less than or equal to the second set humidity threshold;

[0130] When the second ambient humidity is less than or equal to the second set humidity threshold, step S51 is executed; when the second ambient humidity is greater than the second set humidity threshold, step S52 is executed.

[0131] Step S51: Determine that the air conditioner does not pose a risk of condensation.

[0132] Step S52: Determine that the air conditioner has a risk of condensation.

[0133] Wherein, the second set humidity threshold is less than or equal to the first set humidity threshold.

[0134] Specifically, in order to ensure that there is no risk of condensation when the air conditioner is running in the preset wind mode, in this embodiment, the second set humidity threshold is less than the first set humidity threshold mentioned above.

[0135] This method identifies the secondary ambient humidity of the space where the air conditioner operates after the air conditioner has finished dehumidifying, thereby accurately characterizing the indoor humidity after the air conditioner has finished dehumidifying and ensuring that there is still a risk of condensation in the space where the air conditioner is located.

[0136] In addition, in other embodiments, it can be determined that the air conditioner has no risk of condensation when the duration of dehumidification operation is greater than or equal to the set duration; and it can be determined that the air conditioner has a risk of condensation when the duration of dehumidification operation is less than the set duration.

The control device is connected to the outdoor fan, the indoor fan, and the compressor, respectively, to acquire operating data of each component and control the operation of the components according to the relevant steps in any embodiment of the control method for the air conditioner described above.

[0138] Furthermore, this invention also proposes a computer-readable storage medium storing a control program for an air conditioner. When the control program is executed by a processor, it implements the relevant steps of any of the above-described air conditioner control methods.
