Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner intelligent control methods, and in particular to an air conditioner anti-condensation control method, an air conditioner implementing this method, and a computer-readable storage medium. Background Art

[0002] Air conditioners have become essential household appliances in life. The indoor unit of an air conditioner is provided with an air outlet, and the air flow after heat exchange is sent to the room through the air outlet, thereby bringing a comfortable indoor environment to users.

[0003] In the case of relatively high air humidity in hot summer, the air conditioner often operates in cooling mode. During the cooling operation, the air outlet temperature at the air outlet of the indoor unit of the air conditioner is lower than the indoor environment temperature, resulting in water vapor in the humid indoor air condensing into dew on the surface of the air outlet. Excessive dew will cause dew water droplets to drip onto the ground or even be blown out, seriously affecting the user experience.

[0004] In order to prevent dew from forming at the air outlet of the indoor unit of the air conditioner during the cooling operation, the existing method is to set a heating element at the air outlet of the indoor unit of the air conditioner, and turn on the heating element to heat the air flow at the air outlet of the indoor unit of the air conditioner, so that the temperature difference between the air outlet temperature at the air outlet of the indoor unit of the air conditioner and the indoor environment temperature becomes smaller, thereby preventing dew from forming at the air outlet of the indoor unit of the air conditioner.

[0005] However, during the process of turning on the heating element to heat the air flow at the air outlet of the indoor unit of the air conditioner in the existing method, the heating power of the heating element is a fixed preset power. The fixed preset power is generally set according to the moderate dew amount that may be generated at the air outlet. However, the dew amount generated at the air outlet of the indoor unit of the air conditioner is dynamically changing. When the dew amount is small, operating at a fixed preset power that matches the moderate dew amount will result in high energy consumption of the heating element, reduce the service life of the heating element, and cause a relatively high air outlet temperature at the air outlet of the indoor unit of the air conditioner, thereby affecting the cooling heat exchange effect and efficiency of the indoor environment; when the dew amount is large, operating at a fixed preset power that matches the moderate dew amount will result in the heating operation of the heating element being unable to eliminate a large amount of dew at the air outlet, and there will still be a phenomenon of dew water droplets dripping onto the ground or even being blown out. Summary of the Invention

[0006] The first object of the present invention is to provide an air conditioner anti-condensation control method, which can dynamically adjust the heating power of the heating element in real time, so that the heating power of the heating element dynamically matches different dew amounts, thereby completely and effectively eliminating dew generated at the air outlet, improving the user experience, reducing the energy consumption of the heating element, increasing the service life of the heating element, and improving the cooling heat exchange effect and efficiency of the indoor environment.

[0007] The second object of the present invention is to provide an air conditioner for implementing the above air conditioner anti-condensation control method.

[0008] The third object of the present invention is to provide a computer-readable storage medium for implementing the above air conditioner anti-condensation control method.

[0009] To achieve the first object of the present invention, the present invention provides an air conditioner anti-condensation control method. The indoor unit of the air conditioner is provided with an air outlet, and a heating element is arranged at the air outlet. The air conditioner anti-condensation control method includes: controlling the air conditioner to operate in the cooling mode and controlling the heating element to start operating at a preset heating power; obtaining the indoor environmental temperature T1 and the indoor environmental humidity R1, and calculating and obtaining the dew point temperature T2 at which condensation occurs at the air outlet according to the indoor environmental temperature T1 and the indoor environmental humidity R1; determining the target air outlet temperature T3 = T2 + T0, where T0 is a preset increased temperature; calculating and obtaining the air outlet temperature difference ΔT = T3 - T4, where T4 is the real-time air outlet temperature of the air outlet; calculating and obtaining the real-time heating power P of the heating element according to the operating frequency f of the compressor of the air conditioner, the duration t of the cooling mode operation, and the air outlet temperature difference ΔT, and controlling the heating element to operate at the real-time heating power P, and the real-time heating power P is greater than the preset heating power.

[0010] As can be seen from the above solution, the air conditioner anti-condensation control method of the present invention calculates and obtains the real-time heating power P of the heating element, fully considering multiple factors affecting condensation: the operating frequency f of the compressor, the duration t of the cooling mode operation, the real-time air outlet temperature T4 of the air outlet, the indoor environmental temperature T1, and the indoor environmental humidity R1. Among them, the duration t of the cooling mode operation, the real-time air outlet temperature T4 of the air outlet, the indoor environmental temperature T1, and the indoor environmental humidity R1 are all dynamically changing data. Therefore, the heating power of the heating element can be adjusted in real time and dynamically to the real-time heating power P, so that the real-time heating power P of the heating element dynamically matches different condensation amounts, thereby completely and effectively eliminating condensation at the air outlet, improving the user experience, reducing the energy consumption of the heating element, increasing the service life of the heating element, and improving the cooling and heat exchange effect and efficiency of the indoor environment.

[0011] A preferred solution is that the dew point temperature where A is the first coefficient threshold and B is the second coefficient threshold.

[0012] As can be seen from the above solution, the air conditioner anti-condensation control method of the present invention calculates and obtains the real-time dew point temperature T2 for real-time determination of whether the air outlet meets the condensation generation condition according to the real-time dynamically changing indoor ambient temperature T1 and indoor ambient humidity R1, thereby taking into account multiple factors that may affect condensation generation, so as to accurately and dynamically obtain in real time the real-time dew point temperature T2 for real-time determination of whether the air outlet meets the condensation generation condition, providing a guarantee condition for completely and effectively eliminating condensation at the air outlet.

[0013] A further solution is that the first coefficient threshold A is a value between 15 and 20.

[0014] A further solution is that the second coefficient threshold B is 243.5.

[0015] A further solution is that the real-time heating power P = f×(1 + C×t)×D×ΔT; where C is the third coefficient threshold and D is the fourth coefficient threshold.

[0016] As can be seen from the above solution, the air conditioner anti-condensation control method of the present invention calculates and obtains the real-time heating power P of the heating element, fully considering multiple factors that affect condensation generation: the operating frequency f of the compressor, the duration t of refrigeration mode operation, the real-time air outlet temperature T4 of the air outlet, the indoor ambient temperature T1 and the indoor ambient humidity R1. Among them, the duration t of refrigeration mode operation, the real-time air outlet temperature T4 of the air outlet, the indoor ambient temperature T1 and the indoor ambient humidity R1 are all dynamically changing data. Therefore, the heating power of the heating element can be adjusted in real time and dynamically to the real-time heating power P, so that the real-time heating power P of the heating element dynamically matches different condensation amounts, thereby completely and effectively eliminating condensation at the air outlet, improving the user experience, reducing the energy consumption of the heating element, increasing the service life of the heating element, and improving the refrigeration and heat exchange effect and efficiency of the indoor environment.

[0017] A further solution is that the third coefficient threshold C is a value between 0.1 and 0.9.

[0018] A further solution is that the fourth coefficient threshold D is a value between 1 and 1.5.

[0019] A further solution is that the preset increased temperature T0 is a temperature value between 2°C and 5°C.

[0022] Figure 1 is a flowchart of an embodiment of the air conditioner anti-condensation control method of the present invention.

[0023] The present invention will be further described below in conjunction with the drawings and embodiments. Detailed Embodiment

[0024] Embodiment of the air conditioner anti-condensation control method:

[0025] In this embodiment, the indoor unit of the air conditioner is provided with an air outlet, and a heating element and a first temperature sensor are arranged at the air outlet. The indoor unit is also provided with a second temperature sensor and a humidity sensor. Among them, the first temperature sensor is used to detect the real-time air outlet temperature T4 of the air outlet, the second temperature sensor is used to detect the indoor environment temperature T1, and the humidity sensor is used to detect the indoor environment humidity R1.

[0026] Refer to Figure 1 , which is a flowchart of the air conditioner anti-condensation control method. The specific steps of the air conditioner anti-condensation control method in this embodiment are as follows.

[0027] First, execute step S11, control the air conditioner to operate in the cooling mode, and control the heating element to start running at a preset heating power. That is, the user sends a start signal and a running mode signal to the air conditioner through the remote control. Then the circuit board of the air conditioner receives the start signal and the running mode signal, so the circuit board controls the air conditioner to start and operate in the cooling mode. And when it is recognized that the air conditioner is operating in the cooling mode, it indicates that there is a possibility of condensation at the air outlet of the indoor unit. Then the circuit board synchronously controls the heating element to start running at a preset heating power to prevent condensation from occurring at the air outlet of the indoor unit. Among them, when the air conditioner is operating in the cooling mode, the compressor of the air conditioner runs at a preset operating frequency f. Then execute step S12, detect and obtain the indoor environment temperature T1 through the second temperature sensor, detect and obtain the indoor environment humidity R1 through the humidity sensor, and detect and obtain the real-time air outlet temperature T4 of the air outlet through the first temperature sensor. Among them, the indoor environment temperature T1, the indoor environment humidity R1, and the real-time air outlet temperature T4 of the air outlet are all real-time dynamic change data.

[0028] Subsequently, execute step S13, calculate and obtain the dew point temperature T2 of the air outlet for condensation according to the indoor environment temperature T1 and the indoor environment humidity R1. This dew point temperature T2 is used to judge whether the air outlet meets the conditions for condensation at this time. Once the real-time air outlet temperature T4 of the air outlet reaches this dew point temperature T2, condensation is likely to occur at the air outlet.

[0029] Specifically, the dew point temperature of this embodiment Where A is the first coefficient threshold and B is the second coefficient threshold. Preferably, in this embodiment, the first coefficient threshold A is a value between 15 and 20, and the second coefficient threshold B is 243.5. More preferably, the first coefficient threshold A of this embodiment is 17.27, and then more preferably:

[0030] Dew point temperature

[0031] It can be seen that the anti-condensation control method of the air conditioner in this embodiment calculates and obtains the real-time dew point temperature T2 for real-time judgment of whether the air outlet meets the condensation generation conditions according to the real-time dynamically changing indoor environmental temperature T1 and indoor environmental humidity R1, thereby taking into account multiple factors that may affect the generation of condensation, so as to accurately and real-time dynamically obtain the real-time dew point temperature T2 for real-time judgment of whether the air outlet meets the condensation generation conditions, providing guarantee conditions for thoroughly and effectively eliminating the condensation at the air outlet.

[0032] Then step S14 is executed to determine that the target air outlet temperature T3 = T2 + T0, where T0 is a preset increased temperature. Among them, the target air outlet temperature T3 of the air outlet is mainly to solve the problem of condensation at the air outlet, so it is required that the target temperature T3 of the air outlet is higher than the dew point temperature T2, and at the same time, it is required that there is a certain temperature margin between the target air outlet temperature T3 and the dew point temperature T2. Therefore, the preset increased temperature T0 is added to the dew point temperature T2 to obtain the target air outlet temperature T3. When the air outlet temperature reaches the target air outlet temperature T3, the problem of condensation at the air outlet can be thoroughly and effectively eliminated. Preferably, the preset increased temperature T0 in this embodiment is a temperature value between 2°C and 5°C.

[0033] Subsequently, step S15 is executed to calculate and obtain the air outlet temperature difference ΔT = T3 - T4, where T4 is the real-time air outlet temperature of the air outlet, that is, the first temperature sensor detects the real-time air outlet temperature T4 of the air outlet in real time. Since the air conditioner operates in the cooling mode and in order to prevent condensation at the air outlet, the target air outlet temperature T3 of the air outlet must be greater than the real-time air outlet temperature T4 of the air outlet. And the air outlet temperature difference ΔT in this embodiment mainly affects the dynamic adjustment of the real-time heating power P of the subsequent heating element. The larger the air outlet temperature difference ΔT, the greater the real-time heating power P of the heating element needs to be adjusted.

[0034] After that, step S16 is executed to calculate and obtain the real-time heating power P of the heating element according to the operating frequency f of the compressor of the air conditioner, the duration t of the air conditioner operating in the cooling mode, and the air outlet temperature difference ΔT.

[0035] Specifically, the real-time heating power P of the heating element in this embodiment is P = f×(1 + C×t)×D×ΔT, where C is the third coefficient threshold and D is the fourth coefficient threshold. Preferably, the third coefficient threshold C in this embodiment is a value between 0.1 and 0.9, and the fourth coefficient threshold D is a value between 1 and 1.5.

[0036] Since the operating frequency f of the compressor and the duration t of the air conditioner operating in the cooling mode will affect the real-time outlet air temperature T4, the operating frequency f of the compressor and the duration t of the air conditioner operating in the cooling mode will determine the change of the real-time outlet air temperature T4. This change of the real-time outlet air temperature T4 will affect the rate of condensation at the outlet. Therefore, an adjustment coefficient is obtained by calculating f×(1 + C×t) to adjust the real-time heating power P of the heating element, providing a guarantee condition for completely and effectively eliminating condensation at the outlet.

[0037] In addition, the fourth coefficient threshold D in this embodiment is equivalent to a proportionality coefficient, making the calculation of the real-time heating power P of the heating element more accurate.

[0038] Then step S17 is executed to control the heating element to operate at the real-time heating power P, thereby completely and effectively eliminating condensation at the outlet and improving the user experience.

[0039] Specifically, the real-time heating power P of the heating element in this embodiment is greater than the preset heating power of the heating element when it is just turned on. Because when the air conditioner cooling mode is just turned on, there will be no condensation problem at the outlet. Therefore, the heating element is turned on and operates at a smaller preset heating power, which can reduce the energy consumption of the heating element, improve the service life of the heating element, and at the same time avoid a large impact on the outlet air temperature caused by the heating of the heating element, and can improve the cooling heat exchange effect and efficiency of the indoor environment.

[0040] Therefore, the air conditioner anti-condensation control method in this embodiment calculates and obtains the real-time heating power P of the heating element, fully considering multiple factors affecting condensation: the operating frequency f of the compressor, the duration t of the cooling mode operation, the real-time outlet air temperature T4, the indoor environment temperature T1, and the indoor environment humidity R1. Among them, the duration t of the cooling mode operation, the real-time outlet air temperature T4, the indoor environment temperature T1, and the indoor environment humidity R1 are all dynamically changing data. Therefore, the heating power of the heating element can be dynamically adjusted to the real-time heating power P in real time, so that the real-time heating power P of the heating element dynamically matches different condensation amounts, thereby completely and effectively eliminating condensation at the outlet, improving the user experience, reducing the energy consumption of the heating element, improving the service life of the heating element, and improving the cooling heat exchange effect and efficiency of the indoor environment.
