[0047] As described in the background section, during air conditioner operation, the convergence of hot and cold air easily leads to condensation, causing water droplets to fall and severely impacting the user experience. Currently, existing anti-condensation control schemes for air conditioners typically use outlet humidity or temperature as the control reference parameters. For example, by detecting the outlet humidity or temperature, the air conditioner's operating parameters are adjusted to avoid the dew point temperature and thus prevent condensation. The designers of this application found in their research that these control reference parameters cannot directly reflect the time when condensation occurs, resulting in inaccurate anti-condensation control of the air conditioner, severely affecting user comfort and causing a poor user experience. Furthermore, it was also found that current anti-condensation control schemes generally require prolonged changes in the air conditioner's operating state, which also significantly impacts user comfort and results in a poor user experience.

[0048] To address the aforementioned technical problems, embodiments of the present invention provide a method for calculating condensation generation time, an air conditioner anti-condensation control method, and an air conditioner, which can effectively improve the accuracy of anti-condensation control and enhance user comfort.

[0049] 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.

[0050] Please see Figure 1 The condensation generation time calculation method provided in this invention is applied to air conditioners. The condensation generation time represents the theoretical operating time from the current operating state of the air conditioner to the formation of condensation on the condensate block. This condensation generation time calculation method can be used to calculate the condensation generation time for use in air conditioner anti-condensation control methods, thereby improving user comfort. The condensation generation time calculation method includes the following steps:

[0051] Step S100: During the operation of the air conditioner, the surface temperature of the condensate on the air conditioner and the dew point temperature of the indoor environment are obtained.

[0052] In step S100, condensate refers to materials on the air conditioner that are prone to condensation during operation. The condensate surface temperature refers to the surface temperature of these materials on the air conditioner, denoted by T. 凝 The dew point temperature, denoted by Td, represents the critical temperature at which condensation occurs on an air conditioner under the current environment. The condensate can be found on the air outlet panel, air guide plate, etc.

[0053] Step S200: Calculate the condensation time based on the surface temperature and dew point temperature of the condensate.

[0054] The condensation generation time calculation method provided in this invention calculates the condensation generation time by using the surface temperature of the condensate body and the dew point temperature. The condensation generation time can directly reflect the theoretical operating time from the current operating state of the air conditioner to the generation of condensation on the condensate body on the air conditioner. By using the condensation generation time as the control benchmark parameter for anti-condensation control, it can more directly reflect the time when the condensation phenomenon occurs, effectively improve the accuracy of anti-condensation control, and thus improve user comfort.

[0055] Please see Figure 2 Furthermore, to make the explanation of the technical solution clearer, the embodiments of the present invention use the condensate as the air outlet panel and the surface temperature of the condensate as the surface temperature of the air outlet panel as an example for detailed explanation. Step S100 may include the following sub-steps S110 to S140. It should be understood that the step of obtaining the dew point temperature of the indoor environment may include the following sub-steps S110 to S120, and the step of obtaining the surface temperature of the condensate of the air conditioner may include the following sub-steps S130 to S140.

[0056] Sub-step S110: Obtain indoor ambient temperature and humidity during air conditioner operation.

[0057] It should be noted that after the user turns on the air conditioner, they set its operating mode and temperature. During operation, the air conditioner collects indoor ambient temperature and humidity data via temperature and humidity sensors, recording the cumulative operating time since the air conditioner was turned on. To ensure data validity, data can be collected continuously for a set period, which can be set according to actual needs, for example, longer than 1 minute, thus obtaining multiple sets of indoor ambient temperature and humidity data.

[0058] Sub-step S120 calculates the dew point temperature of the indoor environment based on the indoor ambient temperature and humidity.

[0059] To ensure the accuracy of the data calculation, the maximum and minimum values ​​of multiple indoor ambient temperature and humidity data were removed, and the average value was calculated. The corresponding dew point temperature was then calculated based on the average value of the indoor ambient temperature and humidity. It should be noted that calculating dew point temperature from indoor ambient temperature and humidity is a very mature technology, and relevant existing technologies can be referenced; therefore, it will not be elaborated upon here.

[0060] Sub-step S130: Obtain the indoor fan air volume, evaporator temperature, air guide plate angle, and indoor ambient temperature.

[0061] In sub-step S130, the internal fan speed and internal fan impeller radius can be obtained, wherein the internal fan speed is positively correlated with the internal fan air volume. In this embodiment, the internal fan air volume is calculated according to the following formula:

[0062] V = K * 2 * R 2 *π*n;

[0063] Where V represents the air volume of the internal fan, the coefficient K is a preset value that can be measured in the experiment, R represents the impeller radius of the internal fan, and n represents the rotational speed of the internal fan.

[0064] Please see Figure 3 In sub-step S130, the step of obtaining the evaporator temperature may include the following sub-steps S131 to S136.

[0065] Sub-step S131: Obtain multiple first evaporator sampling temperatures during the operation of the air conditioner within a preset time period.

[0066] In sub-step S131, the sampling temperature of the first evaporator is obtained by the evaporator coil temperature sensor.

[0067] Sub-step S132: Calculate the average value of the sampling temperatures of multiple first evaporators to obtain the average value of the sampling temperatures of the first evaporators.

[0068] Among them, the average temperature of the first evaporator is T 蒸1 express.

[0069] Sub-step S133: Obtain multiple second evaporator sampling temperatures during the operation of the air conditioner within another preset time period.

[0070] In sub-step S133, the sampling temperature of the second evaporator is obtained through an evaporator coil temperature sensor. The preset time period is the same as the preset time period in sub-step S131.

[0071] Sub-step S134: Calculate the average value of multiple second evaporator sampling temperatures to obtain the average value of the second evaporator sampling temperature.

[0072] Among them, the average temperature of the second evaporator is T 蒸2 express.

[0073] Sub-step S135: Determine whether the tolerance between the average sampled temperature of the first evaporator and the average sampled temperature of the second evaporator is less than the preset tolerance.

[0074] In sub-step S135, that is, determining T 蒸1 -T 蒸2 Whether the absolute value is less than the preset tolerance Ta, where the preset tolerance can be set according to actual needs, for example, it can be selected as within 1℃.

[0075] Sub-step S136: If yes, then calculate the average of the average sampled temperature of the first evaporator and the average sampled temperature of the second evaporator to obtain the evaporator temperature.

[0076] In sub-step S136, if the tolerance between the average sampled temperature of the first evaporator and the average sampled temperature of the second evaporator is less than the preset tolerance, then take T 蒸1 and T 蒸2 The average value of is used as the evaporator temperature, and the evaporator temperature is represented by T 蒸 .

[0077] Calculating the evaporator temperature in the above manner can improve the calculation accuracy of the evaporator temperature, so as to improve the accuracy of subsequent calculations and controls.

[0078] In addition, confirm the air deflector angle and indoor ambient temperature of the air conditioner for subsequent calculations.

[0079] Please continue to refer to Figure 2 , sub-step S140, calculate the surface temperature of the air outlet panel based on the internal fan air volume, evaporator temperature, air deflector angle and indoor ambient temperature, so as to obtain the surface temperature of the condensate.

[0080] In sub-step S140, the surface temperature of the air outlet panel is calculated according to the following calculation formula:

[0081]

[0082] Among them, T 面 represents the surface temperature of the air outlet panel, V represents the internal fan air volume, T 蒸 represents the evaporator temperature, θ represents the air deflector angle, T 环 represents the indoor ambient temperature, the coefficient a is a preset value, and the coefficient a is related to the size, fin density, shape, etc. of the evaporator. The specific thermal conductivity is measured according to experiments. The coefficient A represents the surface area of the condensate, and the coefficient t1 represents the running time of the air conditioner.

[0083] Also, since the surface temperature T 凝 of the condensate is equal to the surface temperature T_surface of the air outlet panel, the surface temperature T_cond of the condensate is obtained.

[0084] In addition, in order to improve the calculation accuracy of the condensate generation time, in step S200, the condensate generation time is calculated according to the following calculation formula:

[0085] m*C_P*∫T_cond / dt = h*A*(T_cond - Td);<00​​​​

[0087] Please see Figure 4 Furthermore, in some embodiments of the present invention, the surface temperature of the air outlet panel can be compared with the dew point temperature before calculating the condensation generation time to more accurately determine whether there is a risk of condensation under the current operating condition. Before step S200, the method for calculating the condensation generation time may include the following steps S310 to S320.

[0088] Step S310: Determine whether the surface temperature of the condensate is lower than the dew point temperature.

[0089] In step S310, it is determined whether T is satisfied. 面 <Td.

[0090] If the surface temperature of the condensate is lower than the dew point temperature, then the step of calculating the condensation time based on the surface temperature and dew point temperature is executed.

[0091] It should be noted that if T 面 If <Td, there is a risk of condensation. Execute step S200 to calculate the time of condensation.

[0092] In step S320, if the surface temperature of the condensate is greater than or equal to the dew point temperature, the air conditioner is controlled to operate in the set mode.

[0093] In step S320, if T 面 If the temperature is ≥Td, there is no risk of condensation for the time being, and the air conditioner can be controlled to operate according to the set mode. After running for a period of time, it is determined whether the user has turned off the air conditioner. If so, the air conditioner is controlled to turn off according to the user's current setting; if not, the process returns to step S100, and the surface temperature of the condensate on the air conditioner and the dew point temperature of the indoor environment are obtained again for re-judgment and calculation.

[0094] The condensation generation time calculation method provided in this embodiment of the invention uses the condensation generation time as the control benchmark parameter for anti-condensation control, which can more directly reflect the time when condensation occurs, effectively improve the accuracy of anti-condensation control, and thus improve user comfort.

[0095] Please see Figure 5 Furthermore, embodiments of the present invention also provide an air conditioner anti-condensation control method, which uses the condensation generation time calculated by the condensation generation time calculation method provided in any of the above embodiments, and uses the calculated condensation generation time as a control reference parameter. This air conditioner anti-condensation control method includes the following steps.

[0096] Step S400: Determine whether the condensation generation time is greater than the preset condensation generation time.

[0097] In step S400, the preset condensation generation time represents the critical time from the start of operation of the air conditioner to the start of condensation generation. The preset condensation generation time is a preset value, which can be set according to the actual situation.

[0098] In step S500, if the condensation generation time is less than or equal to the preset condensation generation time, the operating parameters of the air conditioner are controlled and adjusted to accelerate condensation generation and condensate discharge.

[0099] In step S500, if the condensation generation time is less than or equal to the preset condensation generation time, it can be considered that the risk of condensation at the condensate body is relatively high. To avoid the problem of long execution time for anti-condensation measures in the prior art, the operating parameters of the air conditioner are controlled and adjusted at this time to accelerate condensation generation and condensate drainage. It should be understood that at this time, condensation is occurring or about to occur at the condensate body. By controlling and adjusting the operating parameters of the air conditioner, the condensation generation is accelerated, and the condensate generated by the condensation is drained as quickly as possible. This avoids condensate being blown out of the air outlet, forming a water blowing phenomenon, thereby accelerating the generation and drainage of condensate in a very short time, preventing the air conditioner from operating for a long time outside the user-set state, and greatly improving user comfort.

[0100] Furthermore, in this embodiment of the invention, step S500 may include: controlling and adjusting the angle of the air guide plate to accelerate condensation generation and direct the air guide plate toward the water guide trough. In other words, controlling and adjusting the operating parameters of the air conditioner is achieved by controlling and adjusting the angle of the air guide plate. This accelerates condensation generation and directs the air guide plate toward the water guide trough on the indoor unit, causing the blown air to blow the condensate into the water guide trough for discharge, avoiding water blowing. This accelerates the generation and discharge of condensate in a very short time, preventing the air conditioner from operating outside the user-set settings for extended periods and greatly improving user comfort.

[0101] In step S600, if the condensation generation time is longer than the preset condensation generation time, the air conditioner is controlled to exit the anti-condensation control and operate in the set mode.

[0102] In step S600, if the condensation generation time is longer than the preset condensation generation time, it can be considered that the risk of condensation at the condensation body is small. At this time, the air conditioner is controlled to exit the anti-condensation control and operate according to the set mode.

[0103] In addition, embodiments of the present invention also provide an air conditioner, which includes a controller for executing a computer program to implement the condensation generation time calculation method provided in any of the above embodiments, and / or the air conditioner anti-condensation control method provided in any of the above embodiments.

[0104] In summary, the condensation generation time calculation method and air conditioner provided in this embodiment of the invention calculate the condensation generation time by using the surface temperature of the condensate body and the dew point temperature. The condensation generation time can directly reflect the theoretical operating time from the current operating state of the air conditioner to the generation of condensation on the condensate body on the air conditioner. By using the condensation generation time as the control benchmark parameter for anti-condensation control, it can more directly reflect the time when the condensation phenomenon occurs, effectively improve the accuracy of anti-condensation control, and thus improve user comfort.

[0105] The air conditioner anti-condensation control method and air conditioner provided in this invention, by using the condensation generation time calculated by the condensation generation time calculation method as the control benchmark parameter, can more directly reflect the time when condensation occurs, effectively improving the accuracy of anti-condensation control and thus improving user comfort. Furthermore, when the condensation generation time is less than or equal to the preset condensation generation time, it indicates that condensation will occur during air conditioner operation. By controlling and adjusting the air conditioner's operating parameters to accelerate condensation generation and condensate drainage, rapid condensation generation can be achieved. This fundamentally solves the adverse effects on users caused by the long-duration anti-condensation mode in existing technologies, improving user comfort.

[0106] This air conditioner utilizes the condensation generation time mechanism, enabling it to quickly and accurately enter and exit anti-condensation mode, reducing the impact of changes in the air conditioner's operating status on users and thus improving user comfort. Furthermore, the calculation of condensation generation time can be achieved through algorithmic innovation using existing modules, saving development costs while adding a selling point to the air conditioner and enhancing brand competitiveness.
