[0036] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Considering that when the indoor humidity is high during cooling operation, condensation is prone to forming on the surface of the indoor heat exchanger. This condensation can drip onto the ground or blow onto the user, affecting the user experience. The anti-condensation mode control method in the related solution achieves this by reducing the compressor frequency at a specific airflow angle. However, in actual use, this does not take into account the different condensation conditions caused by different angles of the indoor unit's air guide and sweeping blades.

[0038] Condensation can occur differently depending on the angle of the indoor unit's air guide and sweeping blades. The air conditioner only enters anti-condensation mode at specific air guide angles (e.g., those where condensation is most severe). This prevents condensation by adjusting the compressor frequency and reducing cooling capacity. However, under harsh operating conditions (i.e., high indoor humidity), condensation can also occur at other air guide angles.

[0039] In addition, the anti-condensation mode in the relevant solutions is achieved by reducing the frequency of the compressor, which is often accompanied by a significant drop in cooling capacity, resulting in a situation where the cooling demand is not met, affecting the user experience.

[0040] It can be seen that the anti-condensation control method of the air conditioner in the relevant scheme does not take into account the influence of different air guide plate positions and sweeping blade angles on the condensation effect of the air conditioner; in addition, the anti-condensation mode in the relevant scheme is achieved by reducing the frequency of the compressor, which is often accompanied by a significant drop in cooling capacity, resulting in a situation where the cooling demand is not met, affecting the user experience.

[0041] Therefore, the solution of the present invention proposes a control method for an air conditioner, specifically a control method for preventing condensation of an air conditioner. By correcting the system operating parameters of the air conditioner under different air guide plate positions and wind sweeping blade angles, the anti-condensation function is achieved while avoiding a significant drop in cooling capacity, thereby improving the user experience.

[0042] According to an embodiment of the present invention, a method for controlling an air conditioner is provided. Figure 1 The flow chart of an embodiment of the method of the present invention is shown. The indoor unit of the air conditioner has an indoor heat exchanger, an indoor fan and an air outlet; the air outlet has an air guide plate and a wind sweeping blade; the air guide plate can be in different fixed positions, and the wind sweeping blade can be in different wind sweeping angles; in the solution of the present invention, Figure 1 As shown, the control method of the air conditioner includes: steps S110 to S150.

[0043] At step S110, when the air conditioner is turned on and in cooling operation, after the air conditioner has been running continuously for a first set time, the current indoor ambient temperature of the air conditioner, the current indoor ambient humidity of the air conditioner, the current indoor heat exchanger pipe temperature of the air conditioner, and the set temperature of the air conditioner are obtained; and the current speed of the indoor fan, the current fixed position of the air guide plate, and the current sweep angle of the sweep blade are obtained; wherein the first set time is such as t1 minutes, and the current indoor ambient temperature of the air conditioner is such as the indoor side ambient temperature T 内环 The current indoor ambient humidity of the air conditioner is such as the indoor relative humidity RH 室内 , the current indoor heat exchanger tube temperature of the air conditioner is such as the evaporator temperature T 内管 The set temperature of the air conditioner is such as the user remote control setting value T 遥控 The current speed of the indoor fan is the speed R corresponding to the current wind speed of the indoor fan. 当前风档 .

[0044] In step S120 , it is determined whether the air conditioner needs to enter a preset anti-condensation mode according to the current indoor ambient temperature of the air conditioner, the current indoor ambient humidity of the air conditioner, and the current indoor heat exchanger pipe temperature of the air conditioner.

[0045] At step S130, if it is determined that the air conditioner needs to enter the preset anti-condensation mode, the air conditioner is controlled to enter the preset anti-condensation mode; of course, if it is determined that the air conditioner does not need to enter the preset anti-condensation mode, the air conditioner is controlled to maintain the current operation.

[0046] At step S140, after controlling the air conditioner to execute the preset anti-condensation mode, the current speed of the indoor fan is corrected according to the current fixed position of the air guide plate, the current sweeping angle of the sweeping blade, and the current indoor ambient humidity of the air conditioner to obtain the corrected speed of the indoor fan; and the indoor fan is controlled to operate at the corrected speed of the indoor fan; wherein, the corrected speed of the indoor fan is such as the system-corrected actual operating speed R.

[0047] At step S150, when the operating stability of the air conditioner reaches the set stability, after a second set time, the air conditioner is controlled to exit the preset anti-condensation mode according to the current indoor ambient temperature and / or the current indoor ambient humidity of the air conditioner.

[0048] The solution of the present invention proposes a control scheme for preventing condensation of an air conditioner, which adds corrections to the system operating parameters of the air conditioner under different air guide plate positions and wind sweeping blade angles; at the same time, through relevant controls, while realizing the anti-condensation function, the cooling capacity demand is met to avoid a significant drop in cooling capacity.

[0049] In some embodiments, the specific process of determining whether the air conditioner needs to enter the preset anti-condensation mode based on the current indoor ambient temperature of the air conditioner, the current indoor ambient humidity of the air conditioner, and the current indoor heat exchanger pipe temperature of the air conditioner in step S120 is described in the following exemplary embodiment.

[0050] The following combination Figure 2 The flowchart of an embodiment of the method of the present invention for determining whether the air conditioner needs to enter the preset anti-condensation mode is shown, further illustrating the specific process of determining whether the air conditioner needs to enter the preset anti-condensation mode in step S120, including: steps S210 to S230.

[0051] Step S210, determining the target humidity threshold of the air conditioner according to the current indoor ambient temperature of the air conditioner and the current indoor heat exchanger pipe temperature of the air conditioner; wherein the target humidity threshold of the air conditioner is such as the preset humidity RH 凝露临界 .

[0052] Step S220 , determining whether the current indoor ambient temperature of the air conditioner is less than or equal to the sum of the set temperature and the set value of the air conditioner, and whether the current indoor ambient humidity of the air conditioner is greater than or equal to the target humidity threshold of the air conditioner.

[0053] Step S230: If it is determined that the conditions are met, it is determined that the air conditioner needs to enter the preset anti-condensation mode; of course, if it is determined that the conditions are not met, it is determined that the air conditioner does not need to enter the preset anti-condensation mode.

[0054] Figure 7 FIG. 1 is a flow chart of an embodiment of a method for controlling condensation prevention in an air conditioner according to the present invention. Figure 7 As shown, the solution of the present invention proposes a method for controlling the anti-condensation of an air conditioner, comprising: step T01, turning on the air conditioner, detecting whether it enters the anti-condensation mode, and then executing step T02.

[0055] Specifically, the air conditioner receives the power-on signal and runs in cooling mode for t1 minutes. Then, the temperature and humidity sensor in the indoor unit detects the current indoor ambient temperature T 内环 , evaporator temperature T 内管 , indoor relative humidity RH 室内 .

[0056] If the indoor ambient temperature T 内环 ≤ User remote control setting value T 遥控 +0.5℃, indoor relative humidity RH 室内 ≥Preset humidity RH 凝露临界 , it means that the current indoor temperature is close to the user's required value, but the ambient humidity is high, higher than the critical humidity for condensation, and there is a risk of condensation aggravating. The system judges and enters the anti-condensation mode. Among them, the preset humidity RH 凝露临界 It is preset in the indoor unit control program and can be controlled by the indoor ambient temperature T 内环 , evaporator temperature T 内管 Calculated.

[0057] In the solution of the present invention, whether the air conditioner needs to enter the preset anti-condensation mode is determined based on the current indoor ambient temperature of the air conditioner, the current indoor ambient humidity of the air conditioner, and the current indoor heat exchanger pipe temperature of the air conditioner, so as to accurately control the timing of the air conditioner entering the preset anti-condensation mode, which is conducive to improving the timeliness and accuracy of anti-condensation control.

[0058] In some embodiments, in step S140, the current speed of the indoor fan is corrected based on the current fixed position of the air guide plate, the current sweeping angle of the sweeping blade, and the current indoor ambient humidity of the air conditioner. For the specific process of obtaining the corrected speed of the indoor fan, please refer to the following exemplary description.

[0059] The following combination Figure 3 The flowchart of an embodiment of correcting the current rotation speed of the indoor fan in the method of the present invention further illustrates the specific process of correcting the current rotation speed of the indoor fan in step S140, including: steps S310 to S330.

[0060] Step S310, determining a first correction coefficient based on the current fixed position of the wind guide plate; determining a second correction coefficient based on the current sweeping angle of the sweeping blade; and using the first correction coefficient and the second correction coefficient as condensation correction coefficients; wherein the first correction coefficient is such as correction coefficient A, and the second correction coefficient is such as correction coefficient B.

[0061] Step S320 , determining a speed compensation value of the indoor fan according to the condensation correction coefficient, the current indoor ambient humidity of the air conditioner, and the current speed of the indoor fan; wherein the speed compensation value of the indoor fan is, for example, a speed compensation value Δr.

[0062] Step S330: Determine the sum of the current rotation speed of the indoor fan and the rotation speed compensation value of the indoor fan as the corrected rotation speed of the indoor fan.

[0063] like Figure 7 As shown, the solution of the present invention proposes a method for controlling condensation prevention of an air conditioner, further comprising:

[0064] Step T02: Determine the condensation correction coefficient according to different fixed positions of the air guide plate and different angles of the wind sweeping blades to obtain the condensation correction coefficient, and then execute step T03.

[0065] Among them, when the air conditioner is turned off, the air guide plate is closed and this angle is set to 0°. Freeze 1, Freeze 2, Freeze 3, Freeze 4, and Freeze 5 represent the air guide plate's rotation angles 1, 2, 3, 4, and 5 around the axis, that is, the degree of opening of the air guide plate. The same is true for the sweep blade. When the sweep blade is centered, the angle is set to 0°, and the left and right directions of the air outlet are controlled by rotating around the axis. The angle values ​​corresponding to each fixed position of the air guide plate and the sweep blade are preset in the built-in memory. The user controls the angles of the air guide plate and the sweep blades by using the up / down / left / right sweep buttons on the remote control. The air conditioner detects the freeze position selected by the user, and then opens the air guide plate and rotates the sweep blades to the corresponding angles.

[0066] In step T02, we consider models with both vertical and horizontal sweeping functions, and determine the correction factor based on both the wind deflector and the sweeping blade angle. However, some models lack horizontal sweeping functions, and in these cases, the correction factor can be determined based solely on the wind deflector angle.

[0067] Step T03: Detect the current operating wind speed of the indoor fan, and determine the indoor fan speed compensation value △r based on the indoor ambient temperature and humidity and the condensation correction coefficient.

[0068] The system corrects the actual operating speed R = R 当前风档 +△r, increase the air volume and the air outlet temperature to optimize the condensation situation, and then execute step T04. 当前风档The speed corresponding to the current operating wind speed of the indoor fan.

[0069] In the solution of the present invention, the accuracy of anti-condensation control is improved by adding different air guide plate positions and wind sweeping blade angles to correct the system operating parameters; at the same time, through relevant control, the cooling capacity demand is met while realizing the anti-condensation function.

[0070] In some embodiments, in step S310, a first correction coefficient is determined based on the current fixed position of the air guide plate, including: based on the correspondence between the preset fixed position and the preset correction coefficient, the preset correction coefficient corresponding to the preset fixed position that is the same as the current fixed position of the air guide plate in the correspondence is determined as the correction coefficient corresponding to the current fixed position of the air guide plate, as the first correction coefficient.

[0071] like Figure 7 As shown, the solution of the present invention proposes a control method for preventing condensation of an air conditioner, which also includes: in step T02, specifically, when the fan speed is the same, the different angles of the air guide plate and the wind sweeping blade will cause different condensation conditions around the air outlet and the air guide plate. When the air conditioner is running, the correction coefficient A is determined by detecting the fixed position of the air guide plate: five correction coefficients A1, A2, A3, A4, and A5 are set according to the different fixed positions of the air guide plate. Depending on the different movement mechanisms of the air guide plate (such as a push-out large air guide plate, a single air guide plate, a double air guide plate, etc.), the corresponding correction coefficient is different. Taking a single air guide plate as an example here, the recommended values ​​of the correction coefficients are shown in Table 1.

[0072] Table 1

[0073]

[0074] In the solution of the present invention, by adding corrections to the system operating parameters of the air conditioner under different air guide plate positions, the speed of the indoor fan can be controlled so that the cooling capacity demand can be met while the anti-condensation function is achieved, thereby avoiding a significant drop in cooling capacity.

[0075] In some embodiments, in step S310, a second correction coefficient is determined based on the current sweep angle of the sweep blade, including: based on the correspondence between the preset sweep angle and the preset correction coefficient, the preset correction coefficient corresponding to the preset sweep angle that is the same as the current sweep angle of the sweep blade in the correspondence is determined as the correction coefficient corresponding to the current sweep angle of the sweep blade, as the second correction coefficient.

[0076] like Figure 7As shown, the present invention proposes an air conditioner anti-condensation control method, further comprising: in step T02, similarly, determining a correction coefficient B by detecting the sweep blade angle. The sweep blade's rotatable angle is divided into five regions: the left region (angles 1° to 2°) corresponds to correction coefficient B1, the left center region (angles 2° to 3°) corresponds to correction coefficient B2, the center region (angles 3° to 4°) corresponds to correction coefficient B3, the right center region (angles 4° to 5°) corresponds to correction coefficient B2, and the right region (angles 5° to 6°) corresponds to correction coefficient B1. Generally, the sweep blade's angles 1° to 2° are symmetrical with those 5° to 6°, and those 2° to 3° are symmetrical with those 4° to 5°. The sweep blade's angles 3° to 4° are located in the center region. For details, see Table 2.

[0079] In the solution of the present invention, by adding corrections to the system operating parameters of the air conditioner under different sweep blade angles, the speed of the indoor fan can be controlled so that the cooling capacity demand can be met while the anti-condensation function is achieved, thereby avoiding a significant drop in cooling capacity.

[0080] In some embodiments, the specific process of determining the speed compensation value of the indoor fan according to the condensation correction coefficient, the current indoor ambient humidity of the air conditioner, and the current speed of the indoor fan in step S320 is described in the following exemplary embodiment.

[0081] The following combination Figure 4 The flowchart of an embodiment of determining the speed compensation value of the indoor fan in the method of the present invention further illustrates the specific process of determining the speed compensation value of the indoor fan in step S320, including: steps S410 to S420.

[0082] Step S410, based on the correspondence between the preset speed and the preset speed coefficient, the preset speed coefficient corresponding to the preset speed that is the same as the current speed of the indoor fan in the correspondence is determined as the speed coefficient corresponding to the current speed of the indoor fan, as the speed coefficient of the indoor fan.

[0083] In step S420, a speed compensation value of the indoor fan is calculated according to the condensation correction coefficient, the current indoor humidity of the air conditioner, and the speed coefficient of the indoor fan, as follows:

[0084] △r=(A+B)*K*RH 室内 +C 风档 ;

[0085] in,

[0086] Wherein, Δr is the speed compensation value of the indoor fan; A+B is the condensation correction coefficient, A is the first correction coefficient, B is the second correction coefficient; K is the preset calculation coefficient; RH 室内 is the current indoor ambient humidity of the air conditioner; C 风档 is the speed coefficient of the indoor fan.

[0087] like Figure 7 As shown, the present invention proposes a method for controlling condensation prevention in an air conditioner, further comprising: in step T03, after confirming the correction coefficient A and the correction coefficient B in step T02, the system performs compensation correction on the indoor fan speed. The indoor fan speed is compensated by a preset formula such as formula (1), thereby increasing the air volume, thereby raising the outlet air temperature, improving the condensation situation, and maintaining the stability of the cooling output.

[0088] Speed ​​compensation value △r=(A+B)*K*RH 室内 +C 风档 (1).

[0089] Among them, the K value is a preset parameter based on laboratory tests and is determined by the cooling capacity of the model. The higher the cooling capacity of the unit, the larger the K value. The recommended K value for household 26 and 35 models is 50. In addition, in order to ensure that the noise value during operation meets the national standard requirements, the windshield coefficient C 风档 It is determined according to the current running wind speed of the indoor fan. It is negatively correlated. The higher the current running wind speed of the indoor fan, the higher the wind speed coefficient C. 风档 The smaller the value.

[0090] In the solution of the present invention, by increasing the correction of the system operating parameters of the air conditioner under different air guide plate positions and wind sweeping blade angles, and by controlling the speed of the indoor fan, the cooling capacity demand is met while realizing the anti-condensation function, thereby avoiding a significant drop in cooling capacity.

[0091] In some embodiments, the specific process of controlling the air conditioner to exit the preset anti-condensation mode according to the current indoor ambient temperature and / or the current indoor ambient humidity of the air conditioner in step S150 is described in the following exemplary embodiments.

[0092] The following combination Figure 5 The flowchart of an embodiment of the method of the present invention for controlling the air conditioner to exit the preset anti-condensation mode further illustrates the specific process of controlling the air conditioner to exit the preset anti-condensation mode in step S150, including: steps S510 to S530.

[0093] Step S510, determining whether the current indoor humidity of the air conditioner is less than the target humidity threshold of the air conditioner; wherein the target humidity threshold of the air conditioner is a preset humidity RH 凝露临界 .

[0094] Step S520: If it is determined that the current indoor environmental humidity of the air conditioner is less than the target humidity threshold of the air conditioner, the air conditioner is controlled to exit the preset anti-condensation mode.

[0095] Step S530: If it is determined that the current indoor ambient humidity of the air conditioner is less than the target humidity threshold of the air conditioner, the compressor of the air conditioner is controlled to operate at a reduced frequency until the current indoor ambient temperature of the air conditioner is greater than the sum of the set temperature and the set value of the air conditioner or the current indoor ambient humidity of the air conditioner is less than the target humidity threshold of the air conditioner, and then the air conditioner is controlled to exit the preset anti-condensation mode.

[0096] like Figure 7 As shown, the solution of the present invention proposes an air conditioner anti-condensation control method, which also includes: Step T04: After the system has been running stably for t2 minutes, the relative humidity RH inside the room is detected. 室内 , if the indoor relative humidity RH 室内 <Preset humidity RH 凝露临界 , it means that the current condensation condition is good and the system exits the anti-condensation control; if the indoor relative humidity RH 室内 >Preset humidity RH 凝露临界 , it means that the indoor humidity load is heavy or the evaporator internal pipe temperature is low, and the internal pipe temperature needs to be further increased, thereby increasing the outlet air temperature and reducing condensation. In cooling mode, the internal pipe temperature is increased by reducing the compressor frequency. At the same time, in order to ensure that the indoor ambient temperature does not fluctuate significantly, the compressor frequency is reduced at a rate of 1Hz / 180s until the indoor ambient temperature T 内环 > User remote control setting value T 遥控 +0.5℃ or indoor relative humidity RH 室内 <Preset humidity RH 凝露临界 , the system exits anti-condensation parameter control.

[0097] Some solutions achieve anti-condensation by adjusting the angle of the cabinet's air deflector, focusing on the air deflector's motion, i.e., automatic sweeping mode. Other solutions add an anti-condensation mechanism to achieve anti-condensation by changing the cold airflow direction. The present invention, on the other hand, considers that when the user sets the air deflector to a fixed position (i.e., when the air deflector is stationary), different condensation conditions may occur at different fixed positions. This approach improves condensation by correcting the fan speed. Thus, by adding control logic that prioritizes fan speed correction, insufficient cooling capacity is reduced, achieving anti-condensation while avoiding a significant drop in cooling capacity and improving the user experience.

[0110] Figure 7 FIG. 1 is a flow chart of an embodiment of a method for controlling condensation prevention in an air conditioner according to the present invention. Figure 7 As shown, the solution of the present invention proposes a method for controlling the anti-condensation of an air conditioner, comprising: step T01, turning on the air conditioner, detecting whether it enters the anti-condensation mode, and then executing step T02.

[0111] Specifically, the air conditioner receives the power-on signal and runs in cooling mode for t1 minutes. Then, the temperature and humidity sensor in the indoor unit detects the current indoor ambient temperature T 内环 , evaporator temperature T 内管 , indoor relative humidity RH 室内 .

[0112] If the indoor ambient temperature T 内环 ≤ User remote control setting value T 遥控 +0.5℃, indoor relative humidity RH 室内 ≥Preset humidity RH 凝露临界 , it means that the current indoor temperature is close to the user's required value, but the ambient humidity is high, higher than the critical humidity for condensation, and there is a risk of condensation aggravating. The system judges and enters the anti-condensation mode. Among them, the preset humidity RH 凝露临界 It is preset in the indoor unit control program and can be controlled by the indoor ambient temperature T 内环 , evaporator temperature T 内管 Calculated.

[0113] In the solution of the present invention, whether the air conditioner needs to enter the preset anti-condensation mode is determined based on the current indoor ambient temperature of the air conditioner, the current indoor ambient humidity of the air conditioner, and the current indoor heat exchanger pipe temperature of the air conditioner, so as to accurately control the timing of the air conditioner entering the preset anti-condensation mode, which is conducive to improving the timeliness and accuracy of anti-condensation control.

[0114] In some embodiments, the control unit 104 corrects the current speed of the indoor fan according to the current fixed position of the air guide plate, the current sweep angle of the sweep blade, and the current indoor ambient humidity of the air conditioner to obtain the corrected speed of the indoor fan, including:

[0115] The control unit 104 is further configured to determine a first correction coefficient based on the current fixed position of the air deflector; determine a second correction coefficient based on the current sweep angle of the sweep blade; and use the first correction coefficient and the second correction coefficient as condensation correction coefficients. The first correction coefficient is, for example, correction coefficient A, and the second correction coefficient is, for example, correction coefficient B. The specific functions and processing of the control unit 104 are further described in step S310.

[0116] The control unit 104 is further configured to determine a speed compensation value for the indoor fan based on the condensation correction coefficient, the current indoor humidity of the air conditioner, and the current speed of the indoor fan. The speed compensation value for the indoor fan may be, for example, a speed compensation value Δr. The specific functions and processing of the control unit 104 are further described in step S320.

[0117] The control unit 104 is further configured to determine the sum of the current speed of the indoor fan and the speed compensation value of the indoor fan as the corrected speed of the indoor fan. The specific functions and processing of the control unit 104 are also shown in step S330.

[0118] like Figure 7 As shown, the solution of the present invention proposes a method for controlling condensation prevention of an air conditioner, further comprising:

[0119] Step T02: Determine the condensation correction coefficient according to different fixed positions of the air guide plate and different angles of the wind sweeping blades to obtain the condensation correction coefficient, and then execute step T03.

[0120] In step T02, we consider models with both vertical and horizontal sweeping functions, and determine the correction factor based on both the wind deflector and the sweeping blade angle. However, some models lack horizontal sweeping functions, and in these cases, the correction factor can be determined based solely on the wind deflector angle.

[0121] Step T03: Detect the current operating wind speed of the indoor fan, and determine the indoor fan speed compensation value △r based on the indoor ambient temperature and humidity and the condensation correction coefficient.

[0122] The system corrects the actual operating speed R = R 当前风档 +△r, increase the air volume and the air outlet temperature to optimize the condensation situation, and then execute step T04. 当前风档 The speed corresponding to the current operating wind speed of the indoor fan.

[0123] In the solution of the present invention, the accuracy of anti-condensation control is improved by adding different air guide plate positions and wind sweeping blade angles to correct the system operating parameters; at the same time, through relevant control, the cooling capacity demand is met while realizing the anti-condensation function.

[0124] In some embodiments, the control unit 104 determines a first correction coefficient based on the current freeze position of the air guide plate, including: the control unit 104 is specifically further configured to determine, based on the correspondence between the preset freeze position and the preset correction coefficient, the preset correction coefficient corresponding to the preset freeze position that is the same as the current freeze position of the air guide plate in the correspondence as the correction coefficient corresponding to the current freeze position of the air guide plate, as the first correction coefficient.

[0125] like Figure 7As shown, the solution of the present invention proposes a control method for preventing condensation of an air conditioner, which also includes: in step T02, specifically, when the fan speed is the same, the different angles of the air guide plate and the wind sweeping blade will cause different condensation conditions around the air outlet and the air guide plate. When the air conditioner is running, the correction coefficient A is determined by detecting the fixed position of the air guide plate: five correction coefficients A1, A2, A3, A4, and A5 are set according to the different fixed positions of the air guide plate. Depending on the different movement mechanisms of the air guide plate (such as a push-out large air guide plate, a single air guide plate, a double air guide plate, etc.), the corresponding correction coefficient is different. Taking a single air guide plate as an example here, the recommended values ​​of the correction coefficients are shown in Table 1.

[0126] In the solution of the present invention, by adding corrections to the system operating parameters of the air conditioner under different air guide plate positions, the speed of the indoor fan can be controlled so that the cooling capacity demand can be met while the anti-condensation function is achieved, thereby avoiding a significant drop in cooling capacity.

[0127] In some embodiments, the control unit 104 determines a second correction coefficient based on the current sweep angle of the sweep blade, including: the control unit 104 is specifically further configured to determine, based on the correspondence between the preset sweep angle and the preset correction coefficient, the preset correction coefficient corresponding to the preset sweep angle that is the same as the current sweep angle of the sweep blade in the correspondence, as the correction coefficient corresponding to the current sweep angle of the sweep blade, as the second correction coefficient.

[0128] like Figure 7 As shown, the present invention proposes an air conditioner anti-condensation control method, further comprising: in step T02, similarly, determining a correction coefficient B by detecting the sweep blade angle. The sweep blade's rotatable angle is divided into five regions: the left region (angles 1° to 2°) corresponds to correction coefficient B1, the left center region (angles 2° to 3°) corresponds to correction coefficient B2, the center region (angles 3° to 4°) corresponds to correction coefficient B3, the right center region (angles 4° to 5°) corresponds to correction coefficient B2, and the right region (angles 5° to 6°) corresponds to correction coefficient B1. Generally, the sweep blade's angles 1° to 2° are symmetrical with those 5° to 6°, and those 2° to 3° are symmetrical with those 4° to 5°. The sweep blade's angles 3° to 4° are located in the center region. For details, see Table 2.

[0129] In the solution of the present invention, by adding corrections to the system operating parameters of the air conditioner under different sweep blade angles, the speed of the indoor fan can be controlled so that the cooling capacity demand can be met while the anti-condensation function is achieved, thereby avoiding a significant drop in cooling capacity.

[0130] In some embodiments, the control unit 104 determines the speed compensation value of the indoor fan according to the condensation correction coefficient, the current indoor ambient humidity of the air conditioner, and the current speed of the indoor fan, including:

[0131] The control unit 104 is further configured to, based on the correspondence between the preset speeds and the preset speed coefficients, determine the preset speed coefficient corresponding to the preset speed equal to the current speed of the indoor fan as the speed coefficient corresponding to the current speed of the indoor fan. The specific functions and processing of the control unit 104 are further described in step S410.

[0132] The control unit 104 is further configured to calculate the speed compensation value of the indoor fan according to the condensation correction coefficient, the current indoor ambient humidity of the air conditioner, and the speed coefficient of the indoor fan according to the following formula:

[0133] △r=(A+B)*K*RH 室内 +C 风档 ;

[0134] in,

[0135] Wherein, Δr is the speed compensation value of the indoor fan; A+B is the condensation correction coefficient, A is the first correction coefficient, B is the second correction coefficient; K is the preset calculation coefficient; RH 室内 is the current indoor ambient humidity of the air conditioner; C 风档 The specific functions and processing of the control unit 104 are also shown in step S420.

[0136] like Figure 7 As shown, the present invention proposes a method for controlling condensation prevention in an air conditioner, further comprising: in step T03, after confirming the correction coefficient A and the correction coefficient B in step T02, the system performs compensation correction on the indoor fan speed. The indoor fan speed is compensated by a preset formula such as formula (1), thereby increasing the air volume, thereby raising the outlet air temperature, improving the condensation situation, and maintaining the stability of the cooling output.

[0137] Speed ​​compensation value △r=(A+B)*K*RH 室内 +C 风档 (1).

[0138] Among them, the K value is a preset parameter based on laboratory tests and is determined by the cooling capacity of the model. The higher the cooling capacity of the unit, the larger the K value. The recommended K value for household 26 and 35 models is 50. In addition, in order to ensure that the noise value during operation meets the national standard requirements, the windshield coefficient C 风档It is determined according to the current running wind speed of the indoor fan. It is negatively correlated. The higher the current running wind speed of the indoor fan, the higher the wind speed coefficient C. 风档 The smaller the value.

[0139] In the solution of the present invention, by increasing the correction of the system operating parameters of the air conditioner under different air guide plate positions and wind sweeping blade angles, and by controlling the speed of the indoor fan, the cooling capacity demand is met while realizing the anti-condensation function, thereby avoiding a significant drop in cooling capacity.

[0141] The control unit 104 is further configured to determine whether the current indoor humidity of the air conditioner is less than the target humidity threshold of the air conditioner; wherein the target humidity threshold of the air conditioner is a preset humidity RH 凝露临界 The specific functions and processing of the control unit 104 are also described in step S510.

[0142] The control unit 104 is further configured to control the air conditioner to exit the preset anti-condensation mode if it is determined that the current indoor humidity of the air conditioner is less than the target humidity threshold of the air conditioner. The specific functions and processing of the control unit 104 are also shown in step S520.

[0143] The control unit 104 is further configured to, if it is determined that the current indoor ambient humidity of the air conditioner is not less than the target humidity threshold of the air conditioner, control the compressor of the air conditioner to reduce the frequency of operation until the current indoor ambient temperature of the air conditioner is greater than the sum of the set temperature and the set value of the air conditioner or the current indoor ambient humidity of the air conditioner is less than the target humidity threshold of the air conditioner, and then control the air conditioner to exit the preset anti-condensation mode. The specific functions and processing of the control unit 104 are further described in step S530.

[0144] like Figure 7 As shown, the solution of the present invention proposes an air conditioner anti-condensation control method, which also includes: Step T04: After the system has been running stably for t2 minutes, the relative humidity RH inside the room is detected. 室内 , if the indoor relative humidity RH 室内 <Preset humidity RH 凝露临界 , it means that the current condensation condition is good and the system exits the anti-condensation control; if the indoor relative humidity RH 室内 >Preset humidity RH 凝露临界, it means that the indoor humidity load is heavy or the evaporator internal pipe temperature is low, and the internal pipe temperature needs to be further increased, thereby increasing the air outlet temperature and reducing condensation. At the same time, in order to ensure that the indoor ambient temperature does not fluctuate significantly, the compressor frequency is reduced at a rate of 1Hz / 180s until the indoor ambient temperature T 内环 > User remote control setting value T 遥控 +0.5℃ or indoor relative humidity RH 室内 <Preset humidity RH 凝露临界 , the system exits anti-condensation parameter control.

[0145] Some solutions achieve anti-condensation by adjusting the angle of the cabinet's air deflector, focusing on the air deflector's motion, i.e., automatic sweeping mode. Other solutions add an anti-condensation mechanism to achieve anti-condensation by changing the cold airflow direction. The present invention, on the other hand, considers that when the user sets the air deflector to a fixed position (i.e., when the air deflector is stationary), different condensation conditions may occur at different fixed positions. This approach improves condensation by correcting the fan speed. Thus, by adding control logic that prioritizes fan speed correction, insufficient cooling capacity is reduced, achieving anti-condensation while avoiding a significant drop in cooling capacity and improving the user experience.
