Summary of the Invention

[0003] The problem addressed by this invention is that existing air conditioners' anti-condensation mechanisms are prone to false protection or lack of protection.

[0008] Furthermore, in an optional embodiment, the step of adjusting the operating parameters of the air conditioner based on the condensation generation time further includes:

[0009] If the first condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time, then the air conditioner is controlled to enter a second anti-condensation mode, and the compressor frequency is controlled to decrease to a second preset frequency, wherein the second preset frequency is less than the first preset frequency. Further, in an optional embodiment, the step of controlling and adjusting the operating parameters of the air conditioner based on the condensation generation time further includes:

[0012] If the current operating frequency is greater than the preset comfort frequency, then the compressor is controlled to run at the current operating frequency for a preset time.

[0013] The second condensation generation time of the air conditioner is obtained, wherein the second condensation generation time characterizes the theoretical operating time of the air conditioner from its current operating state to the generation of condensation.

[0014] Based on the different time intervals in which the second condensation occurs, the operating parameters of the air conditioner are controlled and adjusted accordingly until the second condensation occurs at a time longer than the first preset condensation time.

[0015] Furthermore, in an optional embodiment, the step of controlling and adjusting the operating parameters of the air conditioner according to the different time intervals in which the second condensation occurs includes:

[0016] If the second condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time, the air conditioner is controlled to enter a second anti-condensation mode, and the compressor frequency is controlled to decrease to a second preset frequency, wherein the second preset frequency is less than the first preset frequency. Further, in an optional embodiment, the step of adjusting the air conditioner's operating parameters according to different time intervals in which the second condensation generation time occurs includes:

[0017] If the second condensation generation time is greater than N1 times the first condensation generation time and less than or equal to the second preset condensation time, then return to the step of controlling the air conditioner to enter the first anti-condensation mode and controlling the compressor frequency to decrease to the first preset frequency.

[0018] Furthermore, in an optional embodiment, the step of controlling and adjusting the operating parameters of the air conditioner according to the different time intervals in which the second condensation occurs includes:

[0019] If the second condensation generation time is greater than N2 times the first condensation generation time and less than or equal to N1 times the first condensation generation time, then the actual operating temperature of the air conditioner is increased by a preset temperature based on the set temperature, and the speed of the indoor fan is reduced by a preset speed.

[0020] Determine whether the actual operating temperature of the air conditioner after increasing the preset temperature is less than the preset comfort temperature and the speed of the indoor fan after reducing the preset speed is greater than the preset comfort speed, wherein the preset comfort temperature represents the operating temperature of the air conditioner to ensure user comfort and the preset comfort speed represents the operating speed of the indoor fan to ensure user comfort.

[0021] If so, the air conditioner is controlled to run at the actual operating temperature after increasing the preset temperature for the preset time, and the indoor fan is controlled to run at the speed after decreasing the preset speed for the preset time; the second condensation generation time of the air conditioner is obtained again, and the step of controlling and adjusting the operating parameters of the air conditioner according to the different time intervals in which the second condensation generation time is located is executed until the second condensation generation time is greater than the first preset condensation time.

[0022] If not, the angle of the air guide plate is adjusted so that the air guide plate guides the air towards the water guide trough, and the air conditioner is controlled to operate at the set temperature, the indoor fan is controlled to operate at the set speed, and the frequency of the compressor is controlled to increase.

[0023] Furthermore, in an optional embodiment, the step of controlling and adjusting the operating parameters of the air conditioner according to the different time intervals in which the second condensation occurs includes:

[0024] If the second condensation generation time is greater than 0 and less than or equal to N2 times the first condensation generation time, then the angle of the air guide plate is adjusted so that the air guide plate guides the air towards the water guide trough, and the air conditioner is controlled to operate at the set temperature, the internal fan is controlled to operate at the set speed, and the frequency of the compressor is controlled to increase.

[0025] Furthermore, in an optional embodiment, the step of adjusting the operating parameters of the air conditioner based on the condensation generation time further includes:

[0026] If the current operating frequency is less than or equal to the preset comfort frequency, the actual operating temperature of the air conditioner is increased by the preset temperature based on the set temperature, and the speed of the indoor fan is reduced by the preset speed.

[0027] Determine whether the actual operating temperature of the air conditioner after increasing the preset temperature is less than the preset comfort temperature and the speed of the indoor fan after reducing the preset speed is greater than the preset comfort speed, wherein the preset comfort temperature represents the operating temperature of the air conditioner to ensure user comfort and the preset comfort speed represents the operating speed of the indoor fan to ensure user comfort.

[0028] If so, the air conditioner is controlled to run at the actual operating temperature after increasing the preset temperature for the preset time, and the indoor fan is controlled to run at the speed after decreasing the preset speed for the preset time; the second condensation generation time of the air conditioner is obtained again, and the step of controlling and adjusting the operating parameters of the air conditioner according to the different time intervals in which the second condensation generation time is located is executed until the second condensation generation time is greater than the first preset condensation time.

[0029] Further, in an optional embodiment, the condensation generation time includes a second condensation generation time; the step of controlling and adjusting the operating parameters of the air conditioner based on the condensation generation time further includes: in the second anti-condensation mode, after the compressor frequency is reduced to the second preset frequency, determining whether the current operating frequency of the compressor is greater than the preset comfort frequency, wherein the preset comfort frequency represents the minimum operating frequency of the compressor to ensure user comfort.

[0030] If the current operating frequency is greater than the preset comfort frequency, then the compressor is controlled to run at the current operating frequency for a preset time.

[0031] The second condensation generation time of the air conditioner is obtained, wherein the second condensation generation time characterizes the theoretical operating time of the air conditioner from its current operating state to the generation of condensation.

[0032] If the second condensation generation time is greater than 0 and less than or equal to the second preset condensation time, the air conditioner is controlled to enter the first anti-condensation mode, and the compressor frequency is controlled to decrease to the first preset frequency.

[0033] Furthermore, in an optional embodiment, the step of adjusting the operating parameters of the air conditioner based on the condensation generation time further includes:

[0043] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] Please see Figure 1 This invention provides an adaptive anti-condensation control method for air conditioners, applicable to air conditioners such as wall-mounted, floor-standing, and multi-split systems. This adaptive anti-condensation control method effectively prevents condensation from occurring in the air conditioner, offering high control accuracy and improving user comfort. The adaptive anti-condensation control method includes the following steps:

[0045] Step S110: After the air conditioner is turned on, obtain the set temperature of the air conditioner and the indoor ambient temperature and humidity.

[0046] In step S110, after the user turns on the air conditioner, they set the operating mode and the set temperature T. 设 At this time, the set temperature and indoor ambient temperature and humidity are acquired. The indoor ambient temperature and humidity are collected by temperature and humidity sensors. To ensure the validity of the data, the data can be collected continuously for a period of time. The collection time can be set according to actual needs, for example, it can be selected to be greater than 1 minute, so as to obtain multiple indoor ambient temperature and humidity data.

[0047] Step S120: Calculate the dew point temperature based on the indoor ambient temperature and humidity.

[0048] In step S120, the dew point temperature characterizes the critical temperature at which the air conditioner produces condensation under the current environment. To ensure the accuracy of the data calculation, the maximum and minimum values ​​of multiple indoor ambient temperature and humidity data are removed, and the average value is calculated. The corresponding dew point temperature Td is then calculated based on the average value of the indoor ambient temperature and humidity. It should be noted that calculating the dew point temperature Td using indoor ambient temperature and humidity is a very mature technology, and relevant existing technologies can be referenced; therefore, it will not be elaborated further here.

[0049] Step S130: Determine whether the set temperature is less than or equal to the dew point temperature.

[0050] In step S130, the user-set temperature T is... 设 The set temperature is compared with the calculated dew point temperature Td to determine whether it is less than or equal to the dew point temperature.

[0051] Step S140: If the set temperature is less than or equal to the dew point temperature, control the air conditioner to enter the anti-condensation mode.

[0052] In step S140, if the set temperature is less than or equal to the dew point temperature, it can be assumed that condensation may occur during the operation of the air conditioner. Therefore, the air conditioner is controlled to enter anti-condensation mode to prevent condensation. In anti-condensation mode, steps S210, S220, and S300 described below are executed.

[0053] In step S150, if the set temperature is greater than the dew point temperature, the air conditioner is controlled to run normally for a period of time according to the user's current setting mode.

[0054] In step S150, the normal operating time is set according to actual needs. Optionally, the normal operating time is longer than the data acquisition time.

[0055] Step S160: Determine whether a power-off signal has been received. The power-off signal indicates that the user has initiated a power-off action.

[0056] Step S170: If a shutdown signal is received, control the air conditioner to shut down.

[0057] If no shutdown signal is received after step S160, the process returns to step S110 to reacquire the set temperature of the air conditioner and the indoor ambient temperature and humidity, and continues to execute subsequent steps S120 to S170.

[0058] It should be noted that the inventors of this application discovered in their research that in currently available anti-condensation technologies for air conditioners, the assessment of the dew point (dew point temperature) mainly involves setting a single dew point that cannot be adjusted according to the environment (e.g., temperature and / or humidity; different temperature and humidity settings result in different dew point values, with condensation occurring when the temperature is below the dew point or when the humidity is above it). If the temperature is below the dew point or the humidity is above the dew point, the air conditioner enters anti-condensation mode and stops the compressor. However, the dew point changes according to variations in the external environment's temperature and humidity. Therefore, the adaptive anti-condensation control method for air conditioners provided in this invention collects the indoor temperature and humidity data over a certain period during air conditioner operation. The dew point temperature is then calculated based on this data. This allows for the determination of the indoor dew point by collecting data on indoor temperature and humidity. By comparing the user-set temperature with the dew point temperature, the appropriate entry point for the anti-condensation mode can be determined. Different entry dew point temperatures are provided depending on the indoor environment, ensuring the air conditioner can quickly and accurately enter anti-condensation mode, effectively preventing condensation and ensuring user comfort.

[0059] Please see Figure 2 The following details the control after entering the anti-condensation mode. The adaptive anti-condensation control method of this air conditioner may also include the following steps:

[0060] Step S210: Obtain the indoor fan air volume, evaporator temperature, air guide plate angle, and indoor ambient temperature of the air conditioner in the current setting mode.

[0061] In step S210, the evaporator temperature is acquired by an evaporator coil temperature sensor. As an example, i evaporator temperature data points are acquired over a period of time, and their average value T is calculated. 蒸1 Then, after the same time interval, a second set of data is obtained, namely the second set of i evaporator temperature data, and its average value T is calculated. 蒸2 Determine T 蒸1 T 蒸2 Whether the tolerance is less than the preset tolerance (the preset tolerance can be selected to be within 1℃), that is, to determine T. 蒸1 -T 蒸2 If the absolute value is less than the preset tolerance, then take T. 蒸1 T 蒸2 The average value is used to obtain the evaporator temperature T. 蒸 Used for calculations in subsequent steps.

[0062] Confirm the air guide angle θ and obtain the indoor ambient temperature T. 环 First, determine the internal fan speed n of the air conditioner, and then calculate the internal fan air volume based on the internal fan speed n. The calculation formula is as follows:

[0063] V = K * 2 * R 2 *π*n;

[0064] Among them, the internal fan speed n is positively correlated with the internal fan air volume V, the coefficient K can be measured experimentally, and R is the internal fan impeller radius.

[0065] Step S220: Calculate the surface temperature of the air outlet panel based on the air volume of the internal fan, the evaporator temperature, the angle of the air guide plate, and the indoor ambient temperature.

[0066] In step S220, the surface temperature of the air outlet panel characterizes the surface temperature of the panel at the air outlet, expressed in T. 面 This indicates that the surface temperature T of the air outlet panel is... 面 It is calculated using the following formula:

[0067]

[0068] Among them, coefficient a: is a preset value, which is related to the size, fin density, shape, etc. of the evaporator, and the specific thermal conductivity is determined by experiments; coefficient A: is a preset value, which represents the surface area of ​​the condensate, that is, the surface area of ​​the panel at the air outlet; coefficient tc: indicates the running time of the air conditioner.

[0069] Step S230: Obtain the condensation generation time of the air conditioner. The condensation generation time represents the theoretical operating time from the current operating state to the generation of condensation in the air conditioner.

[0070] In step S230, based on the surface temperature T of the air outlet panel... 面 The condensation time t is calculated. The condensation time is calculated based on the following formula:

[0071] m*C_P*∫T_plane / dt=h*A*(T_plane-Td);

[0072] Wherein, coefficient m: a preset value representing the mass of the condensate; coefficient C_P: characterizing the specific heat capacity of the condensate; coefficient h: a preset value related to the condensate material, thickness, area, thermal conductivity, etc.; coefficient A: a preset value representing the surface area of ​​the condensate; and Td: representing the dew point temperature. In this embodiment, the condensate in the above coefficients refers to the air vent panel.

[0073] Step S300: Adjust the operating parameters of the air conditioner according to the condensation generation time to extend the condensation generation time until the condensation generation time is greater than the first preset condensation time.

[0074] In step S300, the operating parameters of the air conditioner can be the compressor frequency, the indoor fan speed, the angle of the air guide vane, the actual operating temperature of the air conditioner, etc., and the operating parameters to be controlled can be set accordingly according to actual needs. By controlling the operating parameters of the air conditioner, the condensation generation time can be extended so that the condensation generation time is greater than the first preset condensation time.

[0075] It should be noted that the first preset condensation time can be considered as the time it takes for the air conditioner to produce condensation under set conditions. When the condensation time exceeds the first preset condensation time, it can be assumed that the air conditioner will not produce condensation. The first preset condensation time can be set according to actual needs. For example, the first preset condensation time can be set as the time from the start of operation of the air conditioner in extreme environments to the start of condensation, or as the time from the start of operation of the air conditioner in extreme environments to the dripping of condensate droplets, or as the time for condensation to begin under other environmental conditions. The extreme environments mentioned above refer to high temperature and high humidity environments. High temperature can be considered as an ambient temperature exceeding the set temperature, and can be set according to actual needs; high humidity can be considered as an ambient humidity exceeding the set humidity, and can be set according to actual needs. The air conditioner can be placed in extreme environments and tested to obtain the corresponding condensation start time and condensate droplet dripping time, thereby obtaining the corresponding set values.

[0076] In this embodiment, to improve the anti-condensation control effect, the condensation generation time is made longer than the time it takes for condensation droplets to fall. The first preset condensation time is set to characterize the time from the start of operation of the air conditioner to the falling of condensation droplets under extreme conditions. The first preset condensation time is denoted by T1.

[0077] This adaptive anti-condensation control method for air conditioners adjusts the operating parameters of the air conditioner based on the condensation generation time, thereby extending the condensation generation time until it exceeds the first preset condensation time, thus preventing condensation from occurring in the air conditioner. It has high control accuracy and improves user comfort.

[0078] Please see Figure 3 Furthermore, to improve the accuracy of anti-condensation control and ensure user comfort, this embodiment adopts a stepped control mode for the anti-condensation mode, which can effectively prevent condensation from occurring in the air conditioner. In this embodiment, step S300 may include the following sub-steps:

[0079] Sub-step S310: Determine whether the first condensation generation time is greater than 0 and less than or equal to the second preset condensation time.

[0080] It should be noted that the condensation generation time includes a first condensation generation time, denoted by t. The first condensation generation time represents the theoretical operating time from the start of operation of the air conditioner to the generation of condensation. The second preset condensation time represents the time from the start of operation of the air conditioner to the start of condensation generation under extreme conditions. The second preset condensation time is denoted by T2. The second preset condensation time is less than the first preset condensation time. In sub-step S310, it is determined whether 0 < t ≤ T2 is satisfied.

[0081] In sub-step S400, if the first condensation generation time is greater than 0 and less than or equal to the second preset condensation time, the air conditioner is controlled to enter the first anti-condensation mode, and the compressor frequency is controlled to decrease to the first preset frequency.

[0082] In sub-step S400, if 0 < t ≤ T2, it can be considered that the first condensation time is relatively short, and the air conditioner may have a significant risk of condensation. Therefore, the air conditioner is controlled to enter the first anti-condensation mode, and the compressor frequency is controlled to decrease to a first preset frequency. The first preset frequency is represented by F1, and can be set according to actual needs. The compressor frequency is represented by F... 压 This indicates that F is controlled. 压 -F1 indicates the current operating frequency of the compressor.

[0083] By reducing the compressor frequency and refrigerant flow rate, the evaporator temperature is increased, the difference between the evaporator temperature and the dew point temperature is reduced, and the time for the first condensation to occur is extended.

[0084] It should be noted that in the first anti-condensation mode, after the step of controlling the compressor frequency to reduce the first preset frequency, sub-steps S410 to S440 described below can continue to be executed.

[0085] In addition, if the result of sub-step S310 is negative, then sub-step S320 is executed.

[0086] Sub-step S320: If the first condensation generation time is greater than the second preset condensation time, then determine whether the first condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time.

[0087] In sub-step S500, if the first condensation generation time is greater than the second preset condensation time but less than or equal to the first preset condensation time, the air conditioner is controlled to enter the second anti-condensation mode, and the compressor frequency is controlled to decrease to the second preset frequency.

[0088] In sub-step S500, the second preset frequency is less than the first preset frequency. The second preset frequency is denoted by F2 and can be set according to actual needs. If T2 < t ≤ T1, it can be considered that the first condensation generation time is relatively long, but there is still a certain risk of condensation. While ensuring comfort, the compressor frequency can be slightly reduced to prolong the first condensation generation time. Therefore, the second preset frequency is less than the first preset frequency, i.e., F2 < F1. In this embodiment, to improve comfort, F2 < 0.5F1 is optional.

[0089] In sub-step S600, if the time for the first condensation to occur is greater than the first preset condensation time, the air conditioner is controlled to exit the anti-condensation mode and operate according to the user-set mode.

[0090] In sub-step S600, if t ≥ T1, it can be considered that the first condensation has been occurring for too long, and the air conditioner will no longer pose a risk of condensation. Therefore, the air conditioner is controlled to exit the anti-condensation mode and operate according to the user-set mode. At this time, to ensure user comfort, the air conditioner's operating parameters are not adjusted. After exiting the anti-condensation mode, the process returns to step S110, re-collects data, and continues with steps S120 to S170.

[0091] In this way, by adjusting the timing of the first condensation, an adaptive stepped anti-condensation control can be implemented, allowing the system to switch between the first and second anti-condensation modes, effectively ensuring user comfort.

[0092] Please see Figure 4 The following describes the control after entering the first anti-condensation mode. Step S300 may also include the following sub-steps 410 to 440.

[0093] In sub-step S410, under the first anti-condensation mode, after the compressor frequency is reduced to a first preset frequency, it is determined whether the current operating frequency of the compressor is greater than the preset comfort frequency, wherein the preset comfort frequency represents the minimum operating frequency of the compressor to ensure user comfort.

[0094] In sub-step S410, the comfort frequency is preset to F. 舒 This indicates that settings can be adjusted according to actual needs. Determining whether the compressor's current operating frequency is greater than the preset comfort frequency can be considered as determining whether the current operating state meets the user's comfort requirements, thus ensuring user comfort.

[0095] Sub-step S420: If the current operating frequency is greater than the preset comfort frequency, control the compressor to run at the current operating frequency for a preset time.

[0096] In sub-step S420, if the current operating frequency F 压 -F1>F 舒 If the current operating state meets the user's comfort requirements, then the system will continue running in the current state for a preset time. The preset time is denoted by T3, and can be set according to actual needs. Optionally, T3 < t.

[0097] Sub-step S430: Obtain the second condensation generation time of the air conditioner.

[0098] In sub-step S420, the condensation generation time includes the aforementioned second condensation generation time, which characterizes the theoretical operating time from the current operating state of the air conditioner to the generation of condensation. The second condensation generation time is denoted by t1. It should be understood that after a preset operating time, the second condensation generation time of the air conditioner is obtained, i.e., the second condensation generation time is calculated, and the calculation method for the second condensation generation time is the same as that for the first condensation generation time. It should be noted that because t and t1 differ in surface temperature due to the different temperatures of the object generating condensation during calculation, when t is calculated, the object's temperature is the same as the ambient temperature, higher than the dew point temperature. However, when t1 is calculated, the air conditioner has already been running for a period of time, and the surface temperature of the object has decreased due to the influence of the air conditioner's cold air; therefore, t1 < t.

[0099] Sub-step S440: Based on the different time intervals in which the second condensation occurs, the operating parameters of the air conditioner are controlled and adjusted accordingly until the second condensation occurs more than the first preset condensation time.

[0100] In sub-step S440, by judging the different time intervals in which the second condensation occurs, it is determined whether the compressor's previous frequency reduction effectively prolonged the first condensation occurrence time, i.e., whether the compressor's previous frequency reduction was effective. Furthermore, based on the different time intervals in which the second condensation occurs, the air conditioner's operating parameters are controlled accordingly, enabling stepped anti-condensation control to ensure user comfort and fundamentally prevent condensation while ensuring user comfort.

[0101] Please see Figure 5 Furthermore, in order to further improve the accuracy of control and ensure user comfort, in this embodiment, sub-step S440 may include the following sub-steps S4401 to S4408.

[0102] Sub-step S4401: Determine whether the second condensation generation time is greater than the second preset condensation time.

[0103] In sub-step S4401, it is determined whether t1 > T2 is satisfied.

[0104] Sub-step S4402: If the second condensation generation time is greater than the second preset condensation time, then determine whether the second condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time.

[0105] In sub-step S4402, it is determined whether T2<t1≤T1 is satisfied.

[0106] If the judgment result of sub-step S4402 is yes, that is, if the second condensation generation time is greater than the second preset condensation time and less than the first preset condensation time, then sub-step S500 is executed to control the air conditioner to enter the second anti-condensation mode and control the compressor frequency to decrease to the second preset frequency, wherein the second preset frequency is less than the first preset frequency. Wherein, if T2 < t1 ≤ T1, it can be considered that the first condensation generation time is relatively long, but there is still a certain risk of condensation. While ensuring comfort, the compressor frequency can be slightly reduced to prolong the first condensation generation time.

[0107] If the judgment result of sub-step S4402 is negative, that is, if the second condensation generation time is greater than the first preset condensation time, then sub-step S600 is executed to control the air conditioner to exit the anti-condensation mode and operate according to the user-set mode.

[0108] It should be understood that if t1≥T1, it can be considered that the second condensation has been generated for too long, and the air conditioner will no longer pose a risk of condensation. In this case, the air conditioner will be controlled to exit the anti-condensation mode and operate according to the user-set mode. At this time, in order to ensure user comfort, the air conditioner's operating parameters will not be adjusted.

[0109] If the judgment result of sub-step S4401 is No, that is, the second condensation generation time is less than or equal to the second preset condensation time, then execute sub-step S4403.

[0110] Sub-step S4403: Determine whether the second condensation generation time is greater than N1 times the first condensation generation time and less than or equal to the second preset condensation time.

[0111] Among them, N1 is a constant less than 1, which can be set accordingly according to actual needs. For example, N1 can be 0.7 ± 0.1, and further optionally N1 = 0.7, that is, determine whether 0.7t < t1 ≤ T2 is satisfied.

[0112] If the judgment result of sub-step S4403 is Yes, that is, if the second condensation generation time is greater than N1 times the first condensation generation time and less than or equal to the second preset condensation time, then return to execute sub-step S400, control the air conditioner to enter the first anti-condensation mode, and control the frequency of the compressor to decrease by the first preset frequency.

[0113] It should be noted that as an example, if 0.7t < t1 ≤ T2, it can be considered that the second condensation generation time is short, and the air conditioner may have a greater condensation risk. Then control the air conditioner to enter the first anti-condensation mode and control the frequency of the compressor to decrease by the first preset frequency.

[0114] If the judgment result of sub-step S4403 is No, then execute sub-step S4404.

[0115] Sub-step S4404: Determine whether the second condensation generation time is greater than N2 times the first condensation generation time and less than or equal to N1 times the first condensation generation time.

[0116] In sub-step S4404, N2 is a constant less than 1, which can be set accordingly according to actual needs. N2 is less than N1. As an example, N2 can be 0.1 ± 0.05, and further optionally N1 = 0.1, that is, determine whether 0.1t < t1 ≤ 0.7t is satisfied.

[0117] If the judgment result of sub-step S4404 is Yes, that is, execute sub-step S440,

[0118] Sub-step S4405: If the second condensation generation time is greater than N2 times the first condensation generation time and less than or equal to N1 times the first condensation generation time, then control the actual operating temperature of the air conditioner to increase by a preset temperature based on the set temperature, and control the rotational speed of the internal fan to decrease by a preset rotational speed.

[0119] In sub-step S4405, as an example, if 0.1t < t1 ≤ 0.7t, it can be considered that the second condensation generation time is very short, and the previous frequency reduction control cannot effectively extend the condensation generation time. At this time, control the actual operating temperature of the air conditioner to increase the preset temperature T 设 on the basis of T 增 to T 设 +T 增 . Increasing the actual operating temperature can reduce the difference from the dew point temperature. And control the speed S 内 of the indoor fan to reduce the preset speed S 减 to S 内 -S 减 . Reducing the speed of the indoor fan is to reduce the air volume, thereby reducing the amount of intersection of hot and cold air.

[0120] It should be noted that both increasing the actual operating temperature and reducing the speed of the indoor fan can extend the second condensation generation time. In this embodiment, in order to ensure comfort and anti-condensation effect, the actual operating temperature and the speed of the indoor fan are controlled simultaneously, and both are judged and adjusted in subsequent steps. It should be understood that in other embodiments, either one of the above two can be selected for control, and it is also possible to extend the second condensation generation time, and either one of the two can be selected for judgment and adjustment in subsequent steps.

[0121] Sub-step S4406: Judge whether it satisfies that the actual operating temperature of the air conditioner after increasing the preset temperature is less than the preset comfort temperature and the speed of the indoor fan after reducing the preset speed is greater than the preset comfort speed, where the preset comfort temperature represents the operating temperature of the air conditioner under the condition of ensuring user comfort, and the preset comfort speed represents the operating speed of the indoor fan under the condition of ensuring user comfort.

[0122] In sub-step S4406, the preset comfort temperature is represented by T 舒 , and the preset comfort speed is represented by S 舒 , both of which can be set accordingly according to actual needs. That is, judge whether it satisfies T 设 +T 增 <T 舒 and S 内 -S 减 >S 舒 .

[0123] Sub-step S4407: If the judgment result of sub-step S4406 is yes, control the air conditioner to operate at the actual operating temperature after increasing the preset temperature for a preset time, and control the indoor fan to operate at the speed after reducing the preset speed for a preset time.

[0124] That is, if it satisfies T 设 +T 增 <T 舒 and S内 -S 减 >S 舒 , the air conditioner is controlled to operate at an actual operating temperature after increasing the preset temperature and the internal fan is controlled to operate at a speed after decreasing the preset speed for a preset time T3.

[0125] After sub-step S4407, sub-step S430 is executed again to obtain the second condensation generation time of the air conditioner, and sub-step S440 is executed. According to different time intervals in which the second condensation generation time is located, the operating parameters of the air conditioner are correspondingly controlled and adjusted until the second condensation generation time is greater than the first preset condensation time.

[0126] If the judgment result of sub-step S4406 is negative, that is, it does not satisfy T 设 +T 增 <T 舒 and S 内 -S 减 >S 舒 , then sub-step S4408 is executed.

[0127] In sub-step S4408, the angle of the air deflector is controlled and adjusted so that the air deflector deflects air towards the water guide groove, and the air conditioner is controlled to operate at the set temperature, the internal fan is controlled to operate at the set speed, and the frequency of the compressor is increased.

[0128] It should be noted that the water guide groove is a conventional setting structure on the indoor unit of the air conditioner for draining condensed water. If it does not satisfy T 设 +T 增 <T 舒 and S 内 -S 减 >S 舒 , it can be considered that the effect of controlling the increase of the actual operating temperature of the air conditioner and the decrease of the internal fan speed on extending the second condensation generation time is also limited. At this time, in order to ensure user comfort, the air conditioner is controlled to operate at the set temperature, the internal fan speed is increased (i.e., the air volume is increased), and the compressor frequency is increased (the evaporator temperature is decreased) to accelerate condensation generation, and the condensed water droplets are blown into the water guide groove and drained away by controlling the angle of the air deflector, so as to avoid the condensation water droplets from dripping and affecting user comfort.

[0129] If the judgment result of sub-step S4404 is negative, that is, the second condensation generation time is greater than 0 and less than or equal to N2 times of the first condensation generation time. As an example, if it satisfies 0 < t1 ≤ 0.1t, then sub-step S4408 is executed.

[0130] It should be noted that if the second condensation generation time is greater than 0 and less than or equal to N2 times the first condensation generation time, the second condensation generation time is already very short. In order to ensure comfort, sub-step S4408 can be executed to accelerate condensation generation and blow the condensed water droplets into the water channel by controlling the angle of the air guide plate, thereby avoiding condensation dripping and affecting user comfort.

[0131] After sub-step S4408, sub-step S600 is executed to control the air conditioner to exit the anti-condensation mode and run according to the user-set mode.

[0132] Please see Figure 4 and Figure 5 In addition, after sub-step S410, if the judgment result of sub-step S410 is negative, that is, if the current operating frequency is less than or equal to the preset comfort frequency, it can be considered that the current operating state does not meet the user's comfort requirements, then sub-steps S4405 to S4408 are executed to improve user comfort.

[0133] Please see Figure 6 The following describes the control after entering the second anti-condensation mode. Step S300 may also include the following sub-steps 510 to 540.

[0134] In sub-step S510, under the second anti-condensation mode, after the compressor frequency is reduced to a second preset frequency, it is determined whether the current operating frequency of the compressor is greater than the preset comfort frequency, wherein the preset comfort frequency represents the minimum operating frequency of the compressor to ensure user comfort.

[0135] Similar to sub-step S410, it is determined whether the current operating frequency of the compressor is greater than the preset comfort frequency, which can be considered as determining whether the current operating state meets the user's comfort requirements, so as to ensure user comfort.

[0136] Sub-step S520: If the current operating frequency is greater than the preset comfort frequency, control the compressor to run at the current operating frequency for a preset time. Similar to sub-step S420.

[0137] Sub-step S530: Obtain the second condensation generation time of the air conditioner, where the second condensation generation time characterizes the theoretical operating time from the current operating state to the generation of condensation in the air conditioner. Similar to sub-step S430.

[0138] In sub-step S540, the operating parameters of the air conditioner are controlled and adjusted according to the different time intervals in which the second condensation occurs, until the second condensation occurs more than the first preset condensation time.

[0139] Sub-step S540 is similar to sub-step S440, except that in this embodiment, since the first condensation generation time in sub-step S540 is relatively long, the second anti-condensation mode is entered. To ensure comfort, the judgment of the different time intervals in which the second condensation generation time falls is relatively simple, and the second condensation generation time t1 can be directly used for judgment. Of course, in other embodiments, the judgment and control method in sub-step S440 can also be referred to, and the relationship between t1 and t can be introduced for judgment.

[0140] Please see Figure 7 Sub-step S540 may include the following sub-steps S5401 to S5402.

[0141] Sub-step S5401: Determine whether the second condensation generation time is greater than 0 and less than or equal to the second preset condensation time.

[0142] In sub-step S5401, it is determined whether 0 < t1 ≤ T2 is satisfied.

[0143] If the judgment result of sub-step S5401 is yes, that is, the second condensation generation time is greater than 0 and less than or equal to the second preset condensation time, then sub-step S400 is executed to control the air conditioner to enter the first anti-condensation mode and control the compressor frequency to decrease to the first preset frequency.

[0144] If 0 < t1 ≤ T2, it can be considered that the second condensation occurs in a short time, and the air conditioner may have a greater risk of condensation. In this case, the air conditioner is controlled to enter the first anti-condensation mode, and the compressor frequency is controlled to decrease to the first preset frequency.

[0145] If the judgment result of sub-step S5401 is negative, that is, the second condensation generation time is greater than the second preset condensation time, then sub-step S5402 is executed.

[0146] Sub-step S5402: Determine whether the second condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time.

[0147] In sub-step S5402, we determine whether T2 < t1 ≤ T1.

[0148] If the judgment result of sub-step S5402 is yes, that is, the second condensation generation time is greater than the second preset condensation time and less than or equal to the first preset condensation time, then return to execute sub-step S500, control the air conditioner to re-enter the second anti-condensation mode, and control the compressor frequency to decrease to the second preset frequency.

[0149] If T2 < t1 ≤ T1, it can be considered that the second condensation takes a relatively long time to form, but there is still a certain risk of condensation. While ensuring comfort, the compressor frequency can be slightly reduced to prolong the time of the first condensation.

[0150] If the judgment result of sub-step S5402 is negative, that is, the second condensation generation time is greater than the first preset condensation time, then sub-step S600 is executed to control the air conditioner to exit the anti-condensation mode and operate according to the user-set mode.

[0151] If t1≥T1, it can be considered that the second condensation has been generated for too long, and the air conditioner will no longer pose a risk of condensation. In this case, the air conditioner will be controlled to exit the anti-condensation mode and operate according to the user-set mode. At this time, in order to ensure user comfort, the air conditioner's operating parameters will not be adjusted.

[0152] Additionally, it should be noted that if the judgment result of sub-step S510 is negative, that is, the current operating frequency of the compressor is less than or equal to the preset comfort frequency, it can be considered that the current operating state does not meet the user's comfort requirements. In this case, sub-step S400 is executed to control the air conditioner to enter the first anti-condensation mode and control the compressor frequency to decrease to the first preset frequency in order to improve user comfort.

[0153] In summary, the adaptive anti-condensation control method for air conditioners provided in this embodiment of the invention can control and adjust the operating parameters of the air conditioner according to the condensation generation time, thereby extending the condensation generation time until it is extended to a value greater than the first preset condensation time, thus avoiding condensation in the air conditioner, achieving high control accuracy, and improving user comfort.

[0157] In summary, the adaptive anti-condensation control method and air conditioner provided in this embodiment of the invention can adjust the operating parameters of the air conditioner according to the condensation generation time, thereby extending the condensation generation time until it exceeds a first preset condensation time, thus preventing condensation from occurring in the air conditioner. This method offers high control accuracy and improves user comfort. Furthermore, it can determine the dew point temperature by collecting indoor ambient temperature and humidity data, and compare the user-set temperature with the dew point temperature to determine the timing for entering the anti-condensation mode. Different dew point temperatures are provided based on different indoor environments, ensuring the air conditioner can quickly and accurately enter the anti-condensation mode, more effectively preventing condensation and guaranteeing user comfort.

Furthermore, the control variables in the anti-condensation mode can be appropriately increased or decreased according to actual needs and the controller's computing power, making the entire anti-condensation mode more versatile. User comfort can also be improved by increasing the judgment amount and load switching amount of the entire anti-condensation mode.
