Description

Technical Field

[0001] This invention relates to the field of insect repellent technology for outdoor air conditioning units, and more specifically, to an air conditioner operation control method, device, and air conditioner. Background Technology

[0002] The outdoor unit of a split-type air conditioner is typically placed on an outdoor wall or ground. Because the outdoor unit usually generates heat, current, and magnetic fields, it easily attracts insects. Current air conditioner outdoor units generally employ measures such as structural sealing and increased material strength to prevent insects from entering and to avoid damage to critical components, thus providing passive insect prevention. However, air conditioners generally have a long service life, and the structural sealing and material strength gradually decrease over time, causing the insect-prevention function to gradually fail. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides an air conditioner operation control method applied to an air conditioner with temperature-sensitive color-changing fan blades. When the temperature of the fan blades is greater than a first preset threshold or less than or equal to a second preset threshold, the fan blades display a color that attracts insects. The method includes: if the indoor ambient temperature meets the user's requirements, acquiring the outdoor ambient temperature and the outdoor heat exchanger temperature; if the air conditioner operates in cooling mode, and the outdoor ambient temperature is less than or equal to the first preset threshold, and the outdoor heat exchanger temperature is less than or equal to the first preset threshold, controlling the compressor frequency and / or the outdoor unit motor speed to raise the outdoor heat exchanger temperature to above the first preset threshold; if the air conditioner operates in heating mode, and the outdoor ambient temperature is greater than the second preset threshold, and the outdoor heat exchanger temperature is greater than the second preset threshold, controlling the compressor frequency and / or the outdoor unit motor speed to lower the outdoor heat exchanger temperature to below or equal to the second preset threshold.

[0004] The air conditioner operation control method provided in this embodiment of the invention can control the color of the fan blades based on the outdoor ambient temperature and the outdoor heat exchanger temperature. When the fan blades are rotating, they actively attract insects. The insects moving around will be drawn into and killed by the strong airflow generated by the rapidly rotating fan blades, thereby playing a role in preventing insects and reducing the failure rate of the air conditioner caused by insects.

[0005] Optionally, when the temperature of the fan blades is less than the first preset threshold and greater than the second preset threshold, the fan blades display an insect-repelling color; the method further includes: when the air conditioner is running in ventilation mode or the outdoor unit is not running, if a start signal for the outdoor unit motor is received, the air conditioner starts with an insect-repelling acceleration greater than a preset start acceleration.

[0006] In this embodiment of the invention, the color of the fan blades can be controlled based on the outdoor ambient temperature and the outdoor heat exchanger temperature. When the fan blades stop rotating, insects can be actively driven away, and the starting speed of the fan can be increased to kill nearby insects, thereby reducing the failure rate of the air conditioner caused by pests.

[0007] Optionally, the method further includes: the air conditioner is operating in cooling mode; if the outdoor ambient temperature is greater than the first preset threshold, it operates normally; if the outdoor ambient temperature is less than or equal to the first preset threshold, and the outdoor heat exchanger temperature is greater than the first preset threshold, it operates normally.

[0008] In this embodiment of the invention, if the outdoor ambient temperature is greater than the first preset threshold and the outdoor heat exchanger temperature is greater than the first preset threshold, the fan blades will display a color that attracts insects. There is no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. The insects moving around will be drawn in and eliminated by the strong airflow generated by the rapidly rotating fan blades, which can reduce the failure rate of the air conditioner caused by insects.

[0009] Optionally, the method further includes: the air conditioner is operating in heating mode; if the outdoor ambient temperature is less than the second preset threshold, it operates normally; if the outdoor ambient temperature is greater than the second preset threshold and the outdoor heat exchanger temperature is less than or equal to the second preset threshold, it operates normally.

[0010] In this embodiment of the invention, if the outdoor ambient temperature is less than the second preset threshold and the outdoor heat exchanger temperature is less than the second preset threshold, the fan blades will display a color that attracts insects. There is no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. The insects moving around will be drawn in and eliminated by the strong airflow generated by the rapidly rotating fan blades, which can reduce the failure rate of the air conditioner caused by insects.

[0011] Optionally, the method further includes: controlling the indoor unit motor speed to decrease.

[0012] Optionally, the formula for calculating the insect-repelling acceleration is as follows: Finsect-repelling = a * Fnormal + b; where Fnormal is the normal starting acceleration of the outdoor unit motor of the air conditioner, Finsect-repelling is the starting acceleration of the outdoor unit motor of the air conditioner under the insect-repelling function, a is the first starting constant, b is the second starting constant, the value of a ranges from 1 to 2, and the value of b ranges from 0 to 3.

[0013] This invention provides a formula for calculating insect-repelling acceleration, which can increase the starting speed of the fan to kill nearby insects and reduce the failure rate of air conditioners caused by insect infestations.

[0014] Optionally, the first preset threshold value ranges from 40 to 50°C; the second preset threshold value ranges from -10 to 0°C.

[0022] Figure 3 A schematic diagram of the structure of an air conditioner operation control device according to an embodiment of the present invention is shown. Detailed Implementation

[0023] 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.

[0024] The air conditioner fan blade in this embodiment of the invention has temperature-sensitive color-changing characteristics. During the operation of the air conditioner, it can actively drive away or attract and kill insects by changing its color, thereby reducing the failure rate of the air conditioner caused by pests.

[0025] Optionally, the manufacturing and characteristics of the above-mentioned thermochromic fan blades are as follows:

[0026] ①Opaque: Thermochromic materials can be sprayed onto the surface of the wind turbine blades, giving the thermochromic coating on the blades thermochromic properties; ②Transparent: Thermochromic materials can be mixed into the manufacturing materials of the wind turbine blades, giving the entire blades thermochromic properties.

[0027] Depending on the materials added, the colors of the fan blades and the temperatures at which they switch colors also vary. For example, the color that attracts insects is yellow or white; the color that repels insects is purple.

[0028] Figure 1 This diagram illustrates a schematic flowchart of an air conditioner operation control method according to an embodiment of the present invention. The method is applied to an air conditioner with temperature-sensitive color-changing fan blades. When the temperature of the fan blades is greater than a first preset threshold or less than or equal to a second preset threshold, the fan blades display a color that attracts insects. The method includes the following steps:

[0029] S102, if the indoor ambient temperature meets the user's requirements, then obtain the outdoor ambient temperature and the outdoor heat exchanger temperature.

[0030] In this context, "indoor ambient temperature meets user requirements" means that the difference between the indoor ambient temperature and the user-set temperature is less than a threshold and remains so for a certain period of time. For example, the difference between the indoor ambient temperature and the user-set temperature is less than 2°C and lasts for 5–15 minutes.

[0031] Outdoor units typically have an outdoor environment probe and an outdoor coil probe, which can detect the outdoor ambient temperature T. 外环 and outdoor heat exchanger temperature T 外盘 Indoor units typically have an indoor environment sensor that can detect the indoor ambient temperature (T). 内环 .

[0032] S104, the air conditioner is operating in cooling mode. If the outdoor ambient temperature is less than or equal to the first preset threshold and the outdoor heat exchanger temperature is less than the first preset threshold, the compressor frequency and / or the outdoor unit motor speed are controlled to raise the outdoor heat exchanger temperature to a level greater than the first preset threshold.

[0033] In outdoor units, the fan blades are usually located before or after the heat exchanger. Driven by the rotation of the fan blades, the airflow passes through the heat exchanger and the fan blades.

[0034] When the air conditioner is operating in cooling mode, the outdoor ambient temperature is generally high. If the outdoor ambient temperature is greater than a first preset threshold, the outdoor heat exchanger temperature is also greater than the first preset threshold, and the air conditioner operates normally. If the outdoor ambient temperature is less than or equal to the first preset threshold, and the outdoor heat exchanger temperature is also less than or equal to the first preset threshold, the outdoor heat exchanger temperature is controlled to rise, thereby increasing the temperature of the fan blades and controlling the fan blades to display colors that attract insects. When the fan blades are working, they actively attract insects by changing colors, and nearby insects are drawn in and eliminated by the strong airflow generated by the rapidly rotating fan blades.

[0035] Specifically, the temperature of the outdoor heat exchanger can be increased by controlling the compressor frequency and / or the outdoor unit motor speed, thereby raising the temperature of the fan blades. For example, increasing the compressor frequency in an air conditioner raises the temperature of the heat exchanger, and the temperature of the air flowing through the fan blades also increases. Since the above control increases the cooling capacity output of the air conditioner, the cooling capacity output of the air conditioner can be further reduced by decreasing the indoor motor speed, thus maintaining a constant indoor temperature environment. Based on this, the above method can also include: controlling the indoor unit motor speed to decrease.

[0036] S106, the air conditioner is operating in heating mode. If the outdoor ambient temperature is greater than the second preset threshold and the outdoor heat exchanger temperature is greater than the second preset threshold, the compressor frequency and / or the outdoor unit motor speed are controlled to reduce the outdoor heat exchanger temperature to less than or equal to the second preset threshold.

[0037] When the air conditioner is operating in heating mode, the outdoor ambient temperature is generally low. If the outdoor ambient temperature is less than or equal to the second preset threshold, the outdoor heat exchanger temperature is also less than or equal to the second preset threshold, and the air conditioner operates normally. If the outdoor ambient temperature is greater than the second preset threshold, and the outdoor heat exchanger temperature is also greater than the second preset threshold, the outdoor heat exchanger temperature is controlled to decrease, thereby reducing the temperature of the fan blades and achieving the purpose of controlling the fan blades to display colors that attract insects.

[0038] Specifically, the temperature of the outdoor heat exchanger can be lowered by controlling the compressor frequency and / or the outdoor unit motor speed, thereby reducing the temperature of the fan blades. For example, increasing the compressor frequency in an air conditioner lowers the heat exchanger temperature, and the temperature of the air flowing through the fan blades also decreases. Since the above control increases the heat output of the air conditioner, the heat output can be further reduced by decreasing the indoor motor speed, thus maintaining a constant indoor temperature. Based on this, the above method can also include: controlling the indoor unit motor speed to decrease.

[0039] The air conditioner operation control method provided in this embodiment of the invention can control the color of the fan blades based on the outdoor ambient temperature and the outdoor heat exchanger temperature. When the fan blades are rotating, they actively attract insects. The insects moving around will be drawn into and killed by the strong airflow generated by the rapidly rotating fan blades, thereby playing a role in preventing insects and reducing the failure rate of the air conditioner caused by insects.

[0040] If the air conditioner is operating in cooling mode, and the outdoor ambient temperature is higher than a first preset threshold, based on the requirement that the outdoor heat exchanger temperature must also be higher than the first preset threshold, then the fan blades will display a color that attracts insects, and there is no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. If the outdoor ambient temperature is less than or equal to the first preset threshold, but the outdoor heat exchanger temperature is higher than the first preset threshold, then the fan blades will also display a color that attracts insects, and there is still no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. Based on this, the above method may also include:

[0041] If the outdoor ambient temperature is greater than the first preset threshold, it will operate normally; if the outdoor ambient temperature is less than or equal to the first preset threshold, and the outdoor heat exchanger temperature is greater than the first preset threshold, it will operate normally. Normal operation means the air conditioner is running normally in cooling mode, without requiring additional control of the compressor frequency or outdoor unit motor speed for insect prevention.

[0042] If the air conditioner is operating in heating mode, and the outdoor ambient temperature is lower than the second preset threshold, based on the requirement that the outdoor heat exchanger temperature must also be lower than the second preset threshold, it can be determined that the outdoor heat exchanger temperature is also lower than the second preset threshold. In this case, the fan blades will display a color that attracts insects, and there is no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. If the outdoor ambient temperature is higher than the second preset threshold, but the outdoor heat exchanger temperature is lower than or equal to the second preset threshold, the fan blades will also display a color that attracts insects, and there is still no need to additionally control the compressor frequency and outdoor unit motor speed for insect prevention. Based on this, the above method may also include:

[0043] When the air conditioner is in heating mode, if the outdoor ambient temperature is less than the second preset threshold, it will operate normally; if the outdoor ambient temperature is greater than the second preset threshold and the outdoor heat exchanger temperature is less than or equal to the second preset threshold, it will operate normally.

[0044] Considering the condition where the outdoor unit of the air conditioner is not operating, this embodiment also provides a scheme for actively repelling insects. Based on this, when the temperature of the fan blades is less than a first preset threshold and greater than a second preset threshold, the fan blades display a color that repels insects. The above method may also include:

[0045] When the air conditioner is running in ventilation mode or the outdoor unit is not running, if it receives a start signal from the outdoor unit motor, it will start with an insect-repelling acceleration greater than the preset start acceleration. In addition to repelling insects through leaf color, the probability of insects escaping can be increased by appropriately increasing the motor's starting speed, thus killing insects around the fan blades.

[0046] In this embodiment, the color of the fan blades can be controlled based on the outdoor ambient temperature and the outdoor heat exchanger temperature. When the fan blades stop rotating, insects can be actively driven away, and the starting speed of the fan can be increased to kill nearby insects, thereby reducing the failure rate of the air conditioner caused by pests.

[0047] For example, the first preset threshold value ranges from 40 to 50°C; the second preset threshold value ranges from -10 to 0°C.

[0048] Studies have found that insects have certain preferences and aversions to specific colors. They prefer yellow and are easily attracted to white, so yellow adhesive paper or white light are often used to kill insects. However, insects usually avoid purple, believing that purple structures have a certain insect-repelling effect.

[0049] For example, when T1 < T 风叶 When T2 < T, the blades are color A, which attracts insects; when T2 < T... 风叶 ≤T1, the blades are between colors A and B; when T3 < T 风叶 When T2 ≤ T2, the blades are color B, which has the function of repelling insects; when T4 < T 风叶 ≤T3, the blade color is between B and C; when T 风叶 ≤T4, the blades are color C, which has the function of attracting insects.

[0050] Among them, T 风叶 The temperature of the wind turbine blades is as follows: First temperature T1, preferably 40-50℃; Second temperature T2, preferably 30-40℃; Third temperature T3, preferably 0-10℃; Fourth temperature T4, preferably -10-0℃; Colors A and C have the function of attracting insects, such as yellow or white; Color B has the function of repelling insects, such as purple.

[0051] During the operation of the air conditioner, when the fan blades are working, they actively attract insects by changing colors. Insects moving around are drawn in and killed by the strong airflow generated by the rapidly rotating fan blades. When the fan blades stop running, they drive away insects by changing colors, reducing the time insects stay on the outdoor unit.

[0052] When the user enables the insect-proof function, when (T 设 -T5)≤T 内环 <(T) 设When the temperature reaches -T6 and continues for a duration of t1, the indoor temperature is considered to have met the user's requirements, and the insect-proof function can be activated. The fifth temperature T5 is preferably -2 to 2℃; the sixth temperature T6 is preferably -2 to 2℃; and the first time t1 is preferably 5 to 15 minutes.

[0053] (1) Cooling mode

[0054] When T1 < T 外环 At that time, the air conditioner was operating normally;

[0055] When T 外环 When T ≤ T1, the air conditioner controls T 外盘 Achieve temperature-sensitive color change of wind turbine blades;

[0056] When T1 < T 外盘 At that time, the air conditioner was operating normally;

[0057] When T 外盘 When T1 is less than or equal to T1, the air conditioner controls the compressor frequency, outdoor unit motor speed, and indoor unit motor speed to ensure that T1 < T1. 外盘 ;

[0058] For example: Detect every 10 minutes, if T... 外盘 If the value is ≤T1, the compressor of the air conditioner will be controlled to increase its frequency by N1, and the indoor unit motor speed will be reduced by F1, until the compressor triggers frequency limiting or the indoor unit motor speed is limited.

[0059] The compressor of an air conditioner increases its frequency, which raises the temperature of the condenser and the temperature of the fan blades. As a result, the cooling capacity output by the air conditioner also increases. By reducing the indoor motor speed, the cooling capacity output of the air conditioner is reduced, thus keeping the indoor temperature environment constant.

[0060] (2) Heating mode

[0061] When T 外环 When T4 is ≤, the air conditioner operates normally;

[0062] When T4 < T 外环 At that time, the air conditioner controls T 外盘 Achieve temperature-sensitive color change of wind turbine blades;

[0063] When T 外盘 When T4 is ≤, the air conditioner operates normally;

[0064] When T4 < T 外盘 At that time, the air conditioner controls the compressor frequency, outdoor unit motor speed, and indoor unit motor speed to make T 外盘 ≤T4;

[0065] For example: Detect every 10 minutes, if T4 < T 外盘If the compressor frequency is increased by N1, the indoor unit motor speed is reduced by F1 until the compressor triggers frequency limiting or the indoor unit motor speed is limited.

[0066] The compressor of the air conditioner increases its frequency, which lowers the temperature of the condenser and the temperature of the fan blades. As a result, the heat output of the air conditioner increases. By reducing the indoor motor speed, the heat output of the air conditioner is reduced, thus keeping the indoor temperature environment constant.

[0067] (3) Ventilation mode / Outdoor unit stops running

[0068] When the air conditioner is turned on in ventilation mode, turned off, or the outdoor unit stops running due to other functions, the fan blades of the outdoor unit also stop rotating. Given the temperature environment in China, the probability of temperatures exceeding the first temperature T1 and falling below the fifth temperature T4 is very low. It can be assumed that when the unit stops, the fan blades are most likely in a temperature range of T3 < T4. 风叶 Between T2 and T2, there is a small probability that it is between T2 and T2. 风叶 ≤T1 or T4<T 风叶 ≤T3, at this time the blades are entirely or partially colored B, which has the function of repelling insects.

[0069] When the outdoor unit motor receives a start signal and restarts, F 驱虫 =a*F 常规 +b

[0070] F 常规 Normal starting acceleration of the outdoor unit motor of the air conditioner; F 驱虫 The starting acceleration of the outdoor unit motor of the air conditioner under the insect repellent function; the first starting constant a, preferably 1 to 2; the second starting constant b, preferably 0 to 3.

[0071] Increasing the starting speed of the motor appropriately can reduce the probability of insects escaping and kill insects around the blades.

[0072] In this embodiment of the invention, the fan blades have temperature-sensitive color-changing characteristics. During the operation of the air conditioner, the blades can actively repel or attract and kill insects by changing their color, thereby reducing the failure rate of the air conditioner caused by pests.

[0091] In this embodiment of the invention, the ability to actively repel or attract and kill insects is achieved by changing the color during the operation of the air conditioner, thereby reducing the failure rate of the air conditioner caused by pests.
