Description

Technical Field

[0001] The present invention relates to the field of air-conditioning control, and in particular to an adjustment method, system and equipment for stable operation of an air-conditioning. Background Art

[0002] An air conditioner is a machine that includes components such as an evaporator, condenser, and compressor that draws in, changes, or treats the air around it.

[0003] In the prior art, when the air conditioner is working in an extreme environment (ambient temperature is too high), it is easy to cause the air conditioner to overheat, thereby causing air conditioner failure. When the external ambient temperature reaches a preset value, the frequency of the compressor is generally adjusted by a step-by-step adjustment method, and the compressor frequency is adjusted to a frequency that does not exceed the maximum operating frequency, so that the temperature of the evaporator and the condenser passively decreases as the compressor frequency decreases.

[0004] When the compressor frequency reduction is too large, it will easily lead to a significant drop in the overall cooling capacity of the air conditioner, resulting in insufficient cooling capacity of the air conditioner. Summary of the invention

[0005] In order to improve the convenience of using an air conditioner and provide a higher cooling capacity under stable operation conditions, the present invention provides an adjustment method, system and device for stable operation of an air conditioner.

[0006] In a first aspect, the present invention provides a method for adjusting the stable operation of an air conditioner, which adopts the following technical solution: A method for adjusting stable operation of an air conditioner, comprising: Get the ambient temperature; Determine a strategy interval based on air conditioning components and ambient temperature, and obtain component temperature based on the air conditioning components; Determine a component strategy corresponding to the component temperature according to the component temperature and the strategy interval; Determine the corresponding adjustment number according to the air conditioning components; According to the adjustment number, the preset adjustment device is controlled to reduce the temperature of the air-conditioning component according to the component strategy.

[0007] By adopting the above technical solution, the air conditioning strategy is transferred from being regulated by the ambient temperature in extreme environments to a method of adjusting the air conditioning operation strategy according to the temperature values ​​of each part of the evaporator, condenser and compressor. The temperature of the evaporator, condenser and compressor is actively lowered according to the temperature of the parts, thereby reducing the frequency reduction of the compressor, providing higher cooling capacity under stable operation conditions, and improving the convenience of using the air conditioner.

[0008] Optionally, also include: Obtaining the adjusted temperature of the air-conditioning component after the adjustment device cools down according to the component strategy; When the adjustment temperature exceeds the preset working threshold, a feedback strategy corresponding to the adjustment temperature is determined according to the adjustment temperature and the strategy interval; Controlling the preset adjustment device according to the adjustment number to lower the temperature of the air-conditioning component according to the feedback strategy, and obtaining the feedback temperature of the air-conditioning component; When the feedback temperature exceeds the preset working threshold, the temperature is updated and adjusted according to the feedback temperature; When the feedback temperature does not exceed a preset operating threshold, the component strategy is updated according to the feedback strategy, the component strategy and the strategy interval.

[0009] By adopting the above technical solution, when the components of the air conditioner and their corresponding adjustment devices are aged, the heat dissipation performance may deteriorate. The temperature of the air conditioner components after adjustment according to the component strategy is detected, and when the temperature is still too high, further strategies are taken to make the temperature reach the working threshold. The effective strategies are fed back to the strategy interval to optimize the adjustment strategies of the air conditioner components and improve the convenience of using the air conditioner.

[0010] Optionally, a component temperature acquisition method is also included, and the component temperature acquisition method includes: When the component temperature exceeds a preset operating threshold, the difference between the component temperature and the operating threshold is calculated and defined as the temperature difference; Determine the corresponding adjustment period according to the temperature difference and obtain the running time of the air conditioner; Calculate the quotient of the operating time and the adjustment period and define it as the number of periods; When the number of cycles is an integer, the change parameters of the component temperature of the adjustment cycle are retrieved from the preset component temperature database according to the running time; A temperature average is determined based on the changing parameters, and the component temperature is updated based on the temperature average.

[0011] By adopting the above technical solution, the time period for adjustment of each position is set according to the temperature change frequency of different parts of the air conditioner, and the average temperature of the air conditioner components in each time period is used as the component temperature, thereby improving the accuracy of temperature detection and the stability of the implementation of the adjustment strategy.

[0012] Optionally, an external machine cooling method is also included, and the external machine cooling method includes: When the temperature of the component exceeds a preset operating threshold, determining whether the air conditioning component is located in the air conditioning outdoor unit according to the air conditioning component; When the air conditioning component is located in the air conditioning outdoor unit, acquiring an outdoor unit image of the air conditioning outdoor unit; Determine whether the outdoor unit is exposed to sunlight based on the outdoor unit image; When the outdoor unit is exposed to sunlight, the exposed area is determined based on the outdoor unit image; Determine the irradiation pole distance according to the irradiation area; The preset reflective device is controlled to unfold to cover the irradiation area according to the irradiation pole distance.

[0013] By adopting the above technical solution, when sunlight shines on the outdoor unit of the air conditioner, it is easy to cause the outer shell of the outdoor unit of the air conditioner to heat up due to thermal radiation, thereby causing the air conditioning components on the outdoor unit to heat up. The sunlight shining on the outdoor unit of the air conditioner is reflected by the reflective device, thereby reducing the situation where the outdoor unit of the air conditioner is heated up due to the influence of sunlight.

[0014] Optionally, the external unit cooling method further includes: When the outdoor unit is exposed to sunlight, historical data of component temperature is retrieved from a preset component temperature database according to a preset trend period; Determine the temperature change trend based on historical data and obtain the installation location of the air conditioner outdoor unit; Retrieve meteorological data from the preset meteorological database according to the installation location; Determine the current time based on changing trends and meteorological data; Determine the angle variation parameters of the sunlight irradiation angle according to the current time and installation location; Determine a region variation parameter of the irradiation region according to the angle variation parameter and the irradiation region; Determine the pole distance variation parameter according to the regional variation parameter; The preset reflective device is controlled to expand according to the pole distance variation parameter as the area of ​​the irradiated area changes.

[0015] By adopting the above technical solution, the meteorological data of the area where the air-conditioning outdoor unit is located is retrieved to predict the changes in the area of ​​the air-conditioning outdoor unit illuminated by sunlight, and then the reflective device is controlled to extend as the illuminated area changes, thereby reducing the situation where the reflective device covers the air-conditioning outdoor unit and causes the heat dissipation performance of the air-conditioning outdoor unit to decrease.

[0016] Optionally, the external unit cooling method further includes: Determine the deployment time of the reflective device according to the pole distance variation parameter; Determine whether there is rainy weather when the reflective device is deployed based on the current time, deployment duration and meteorological data; When the reflective device is deployed and it is rainy, the high temperature position on the outer casing of the air conditioner is determined according to the air conditioner components; Determine the guide area based on the high temperature position; Determine the rainy period of rainy weather based on meteorological data; When the current time is in a rainy period, the preset reflective device is controlled to cover the guide area, and one end of the reflective device is raised away from the high temperature position.

[0017] By adopting the above technical solution, it is determined whether there is rainy weather based on the meteorological data of the area where the air conditioner outdoor unit is located, so that the angle and direction of the reflective device are controlled in rainy weather, so that when precipitation falls on the reflective device, it is affected by the angle of the reflective device and flows to the location of the air conditioning components, thereby improving the cooling efficiency of the air conditioning components.

[0018] Optionally, the external unit cooling method further includes: When the outdoor unit is exposed to sunlight, the light intensity of the exposed area is obtained; When the light intensity exceeds the preset thermal conductivity threshold, the high temperature pole distance is determined according to the high temperature position; When the high temperature pole distance is higher than the irradiation pole distance, the preset reflective device is controlled to cover the high temperature position according to the high temperature pole distance, and the heat dissipation wind direction of the high temperature position is obtained; Based on the situation that the high-temperature pole distance is not higher than the irradiation pole distance, the preset reflective device is raised according to the heat dissipation wind direction to guide the wind direction.

[0019] By adopting the above technical solution, when the temperature of the air-conditioning components is too high, the wind direction of the environment where the air-conditioning outdoor unit is located is detected, and the windward surface of the reflective device is controlled to rise according to the wind direction, thereby directing the airflow blowing toward the air-conditioning outdoor unit to the high-temperature air-conditioning components, thereby improving the cooling efficiency of the air-conditioning components.

[0020] Optionally, the external unit cooling method further includes: When the light intensity exceeds the preset thermal conductivity threshold, the heat dissipation wind speed at the high temperature position is obtained; Determine the corresponding heat dissipation rate according to the ambient temperature and heat dissipation wind speed; Determine the air flow rate based on the heat dissipation rate and temperature difference; Determine the air guide angle according to the air guide volume and high temperature pole distance; The preset reflective device is raised according to the wind guide angle to guide the wind direction.

[0021] By adopting the above technical scheme, the heat dissipation effect of the wind is estimated according to the ambient temperature and the wind speed blowing toward the outdoor unit of the air conditioner, and when the heat dissipation effect is not sufficient to reduce the high temperature of the air-conditioning components, the windward surface of the reflective device is controlled to rise to increase the air guide volume, thereby improving the cooling effect of the wind on the air-conditioning components.

[0022] In a second aspect, the present application provides an adjustment system for stable operation of an air conditioner, which adopts the following technical solution: An adjustment system for stable operation of an air conditioner, comprising: Acquisition module, used to obtain ambient temperature, component temperature, adjustment temperature, feedback temperature, operating time, external machine image, installation position and light intensity; A memory, used to store a program of any of the above-mentioned adjustment methods for stable operation of the air conditioner; The program in the memory can be loaded and executed by the processor.

[0023] In a third aspect, the present application provides an adjustment device for stable operation of an air conditioner, which adopts the following technical solution: An adjustment device for stable operation of an air conditioner comprises a memory and a processor. The memory stores a computer program that can be loaded by the processor and execute any of the above-mentioned adjustment methods for stable operation of an air conditioner.

[0024] By adopting the above technical solution, the air conditioning strategy is transferred from being regulated by the ambient temperature in extreme environments to a method of adjusting the air conditioning operation strategy according to the temperature values ​​of each part of the evaporator, condenser and compressor. The temperature of the evaporator, condenser and compressor is actively lowered according to the temperature of the parts, thereby reducing the frequency reduction of the compressor, providing higher cooling capacity under stable operation conditions, and improving the convenience of using the air conditioner.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The air conditioning strategy is shifted from being regulated by ambient temperature in extreme environments to being regulated by the temperature values ​​of the evaporator, condenser and compressor. The temperature of the evaporator, condenser and compressor is actively lowered according to the temperature of the parts, thereby reducing the frequency reduction of the compressor, providing higher cooling capacity under stable operation conditions and improving the convenience of air conditioning use. 2. When the air conditioner components and their corresponding adjustment devices age, the heat dissipation performance is likely to deteriorate. The temperature of the air conditioner components after adjustment according to the component strategy is detected, and if the temperature is still too high, further strategies are taken to make the temperature reach the working threshold. The effective strategy is fed back to the strategy interval to optimize the adjustment strategy of the air conditioner components and improve the convenience of air conditioning use; 3. According to the temperature change frequency of different parts of the air conditioner, set the time period for adjustment of each position, and use the average temperature of the air conditioner components in each time period as the component temperature, so as to improve the accuracy of temperature detection and the stability of the implementation of the adjustment strategy.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] An embodiment of the present application discloses a method for adjusting the stable operation of an air conditioner. The method is used to shift the air conditioning strategy from being regulated by the ambient temperature (or being regulated by the external ambient temperature and the ambient temperature of the air-conditioned room) in an extreme environment (where the ambient temperature is too high) to a method of adjusting the air conditioning operation strategy based on the temperature values ​​of various parts of the air-conditioning system (such as compressor exhaust temperature, controller temperature, condenser temperature, evaporator temperature, compressor suction temperature, etc.), thereby enabling the air conditioner to provide better refrigeration performance under the same environmental conditions.

[0029] Reference Figure 1 , a method for adjusting the stable operation of an air conditioner, comprising: Step 100: Obtain the ambient temperature.

[0030] Ambient temperature refers to the outdoor temperature value. The ambient temperature can be obtained through a temperature sensor. The method for obtaining the ambient temperature is selected by the staff according to the actual situation and will not be elaborated here.

[0031] Step 101: determining a strategy interval based on air-conditioning components and ambient temperature, and obtaining component temperatures based on air-conditioning components.

[0032] Air conditioning parts refer to components of air conditioning such as evaporator, condenser and compressor. Air conditioning parts can be set in advance or automatically selected in sequence by the program. The setting method of air conditioning parts is selected by the staff according to actual conditions and will not be elaborated here.

[0033] The adjustment device refers to a device such as a condensing fan, an evaporating side fan, etc., which is arranged corresponding to the air-conditioning components and is used to adjust the temperature of the air-conditioning components. The compressor can directly adjust the temperature through frequency modulation. The adjustment device corresponding to the compressor is the compressor itself. The adjustment device is selected by the staff according to actual conditions and will not be elaborated here.

[0034] The adjustment strategy refers to measures such as compressor frequency conversion, fan speed change, etc. to adjust the temperature of air-conditioning components through adjustment devices. The adjustment strategy is selected by the staff according to the actual situation and will not be described here. The strategy interval refers to the temperature interval corresponding to the implementation of the adjustment strategy. The adjustment strategy is implemented according to the strategy interval to adjust the temperature of the air-conditioning components in stages. The strategy interval can be obtained through the strategy interval matching model. The strategy interval matching model refers to a neural network model obtained through sample training in advance.

[0035] The component temperature refers to the real-time temperature value of the air-conditioning component. The component temperature can be obtained through a temperature sensor. The method for obtaining the component temperature is selected by the staff according to the actual situation and will not be elaborated here.

[0036] Step 102: Determine a component strategy corresponding to the component temperature according to the component temperature and the strategy interval.

[0037] The component strategy is the adjustment strategy corresponding to the strategy interval in which the component temperature lies.

[0038] Step 103: Determine the corresponding adjustment number according to the air conditioning component.

[0039] The adjustment number refers to a number set manually to distinguish the adjustment device. The setting method of the adjustment number is selected by the staff according to the actual situation and will not be described here. The adjustment number can be obtained by querying the adjustment database, which refers to a database that records the adjustment numbers of various air-conditioning components and their corresponding adjustment devices in advance.

[0040] Step 104: Control a preset adjustment device according to the adjustment number to reduce the temperature of the air-conditioning component according to the component strategy.

[0041] The air-conditioning components are adjusted in stages according to their temperatures, so that each air-conditioning component can reach the temperature of the best working efficiency under the premise of stable operation under the current environmental conditions, thereby making the air-conditioning as a whole achieve the best cooling performance under the current environmental conditions and improving the convenience of using the air-conditioning.

[0042] Reference Figure 2 , a method for adjusting the stable operation of an air conditioner, further comprising: Step 105: Obtain the adjusted temperature of the air-conditioning component after the adjustment device cools down the component according to the component strategy.

[0043] The adjusted temperature refers to the real-time temperature of the component after the adjustment device adjusts the temperature of the component according to the component strategy control. The adjusted temperature can be obtained through a temperature sensor. The method for obtaining the adjusted temperature is selected by the staff according to actual conditions and will not be elaborated here.

[0044] Step 106: When the adjusted temperature exceeds a preset working threshold, a feedback strategy corresponding to the adjusted temperature is determined according to the adjusted temperature and the strategy interval.

[0045] The working threshold refers to the maximum temperature at which the air conditioning components achieve the best working efficiency. The working threshold is selected by the staff according to the actual situation and will not be described here. If the adjustment temperature exceeds the working threshold, it means that the temperature of the component is too high and needs to be further cooled. The feedback strategy is the adjustment strategy corresponding to the strategy interval where the adjustment temperature is located.

[0046] Step 107: Control a preset adjustment device according to the adjustment number to lower the temperature of the air-conditioning component according to the feedback strategy, and obtain the feedback temperature of the air-conditioning component.

[0047] The feedback temperature is the real-time temperature value of the air-conditioning component after the temperature of the air-conditioning component is further adjusted according to the feedback strategy. The feedback temperature can be obtained through a temperature sensor. The method for obtaining the feedback temperature is selected by the staff according to actual conditions and will not be elaborated here.

[0048] Step 108: When the feedback temperature exceeds a preset working threshold, the temperature is updated and adjusted according to the feedback temperature.

[0049] The feedback temperature exceeding the working threshold value indicates that the temperature of the component is still too high and needs to be further cooled. The adjusted temperature value is updated to the feedback temperature value, so that the temperature is further cooled according to the above steps based on the feedback temperature.

[0050] Step 109: When the feedback temperature does not exceed the preset working threshold, the component strategy is updated according to the feedback strategy, the component strategy and the strategy interval.

[0051] If the feedback temperature does not exceed the working threshold, it means that the component temperature is normal at this time, and the air-conditioning components can operate stably under the current strategy. At this time, the original component strategy is superimposed on the feedback strategy to form a new adjustment strategy, and the new adjustment strategy is updated to the adjustment strategy corresponding to the strategy interval. In this way, during the operation of the air conditioner, the adjustment strategy can be changed in real time according to the temperature adjustment effect, thereby improving the effectiveness of the adjustment strategy.

[0052] Reference Figure 3 , the component temperature acquisition method includes: Step 200: When the temperature of a component exceeds a preset operating threshold, a difference between the temperature of the component and the operating threshold is calculated and defined as a temperature difference.

[0053] The temperature difference is the difference between the component temperature and the working threshold. The temperature difference is used to show the abnormality of the component temperature, so that corresponding measures can be taken according to the abnormality.

[0054] Step 201: Determine a corresponding adjustment period according to the temperature difference, and obtain the operating time of the air conditioner.

[0055] The adjustment cycle refers to the time interval for changing the adjustment strategy. The air conditioner generally obtains the temperature of the component according to a fixed adjustment cycle and selects the adjustment strategy according to the temperature, so that the adjustment strategy matches the current component temperature. The adjustment cycle is selected according to the abnormal degree of the component temperature. When the temperature difference is large, a smaller adjustment cycle is adopted to closely monitor the temperature changes of the air-conditioning components. When the temperature difference is small, a larger adjustment cycle is adopted to save computing power and energy. The adjustment cycle can be obtained by querying the adjustment cycle database. The adjustment cycle database records the temperature difference obtained in advance through experiments and its corresponding adjustment cycle.

[0056] The running time refers to the time the air conditioner runs under the current adjustment cycle. When the adjustment cycle is changed, the running time needs to be reset to zero. The running time can be obtained through the timer. The method for obtaining the running time is selected by the staff according to the actual situation and will not be elaborated here.

[0057] Step 202: Calculate the quotient of the running time and the adjustment period and define it as the number of periods.

[0058] The number of cycles refers to the number of adjustment cycles that have passed in the current time. The number of cycles is used to determine whether the adjustment strategy needs to be changed.

[0059] Step 203: When the number of cycles is an integer, the temperature variation parameters of the components of the adjustment cycle are retrieved from a preset component temperature database according to the running time.

[0060] The cycle number is an integer indicating that the adjustment strategy needs to be changed at this time. The component temperature database refers to a database recording previously obtained component temperatures. The change parameter is all component temperature values ​​obtained within an adjustment cycle before the current time retrieved from the component temperature database.

[0061] Step 204: Determine a temperature average value according to the change parameter, and update the component temperature according to the temperature average value.

[0062] The temperature average value is the arithmetic mean of all component temperature values ​​obtained in an adjustment cycle before the current time. The temperature average value is assigned to the component temperature so that the air conditioner selects an adjustment strategy based on the temperature average value, thereby reducing the situation where the air conditioner operation fluctuates due to erroneous data and improving the stability of the air conditioner operation.

[0063] Reference Figure 4 , the outdoor unit cooling methods include: Step 300: When the temperature of the component exceeds a preset working threshold, it is determined whether the air conditioning component is located in the air conditioning outdoor unit according to the air conditioning component.

[0064] The outdoor unit of an air conditioner refers to a device installed outdoors that is responsible for discharging indoor heat to the outdoors through a refrigeration cycle to regulate the indoor temperature. Air conditioning components such as compressors, condensers and fans are generally installed in the outdoor unit of the air conditioner. You can determine whether the air conditioning components are located in the outdoor unit of the air conditioner by querying the component database. The component database refers to a database that records the various air conditioning components and their installation locations.

[0065] Step 301: When the air conditioning component is located in the air conditioner outdoor unit, an outdoor unit image of the air conditioner outdoor unit is acquired.

[0066] The air conditioning components are located in the air conditioning outdoor unit, which means that the air conditioning components are easily affected by the outdoor environment. The outdoor unit image is a picture of the air conditioning outdoor unit. The outdoor unit image can be obtained through a camera. The method for obtaining the outdoor unit image is selected by the staff according to actual conditions and will not be elaborated here.

[0067] Step 302: Determine whether the outdoor unit is exposed to sunlight based on the outdoor unit image.

[0068] When the outdoor unit is exposed to sunlight, the color on the outdoor unit shell is brighter. When the outdoor unit is not exposed to sunlight, the color on the outdoor unit shell is darker. The color on the air conditioner outdoor unit shell in the outdoor unit image can be used to determine whether the outdoor unit image is exposed to sunlight. The method for determining whether the outdoor unit is exposed to sunlight is selected by the staff based on actual conditions and will not be elaborated here.

[0069] Step 303: When the outdoor unit is illuminated by sunlight, the illuminated area is determined according to the outdoor unit image.

[0070] The irradiated area refers to the area on the external unit casing that is illuminated by sunlight. The irradiated area can be obtained by identifying the color on the external unit casing of the air conditioner in the external unit image. The identification method of the irradiated area is selected by the staff according to the actual situation and will not be elaborated here.

[0071] Step 304: Determine the irradiation distance according to the irradiation area.

[0072] The irradiation distance refers to the maximum length of the irradiation area in the direction of sunlight. The identification method of the sunlight irradiation direction and the irradiation distance is selected by the staff according to the actual situation and will not be elaborated here.

[0073] Step 305: Control the preset reflective device to unfold to cover the irradiation area according to the irradiation pole distance.

[0074] A reflective device refers to a device that is installed above the air conditioner outdoor unit and is used to cover the irradiation area to reflect the sunlight that shines in the irradiation area. The reflective device generally includes a reel, a reflective cloth and a bracket. The movement of the bracket drives the reflective cloth to extend from the reel to the air conditioner outdoor unit, or to retract from the air conditioner outdoor unit to the reel. The reflective device is selected by the staff according to actual conditions and will not be elaborated here.

[0075] When the temperature of the outdoor unit is too high, it is easy to cause the temperature of the air-conditioning components such as the compressor, condenser and fan in the outdoor unit to rise, thereby causing the original adjustment strategy to take effect. The reflective device is used to cover the irradiation area to reduce direct sunlight on the air-conditioning outdoor unit, causing the temperature of the outdoor unit to rise, and then causing the temperature of the air-conditioning components in the outdoor unit to rise, thereby improving the stability of the air-conditioning adjustment strategy.

[0076] Reference Figure 5 , the outdoor unit cooling method also includes: Step 306: When the outdoor unit is exposed to sunlight, historical data of component temperature is retrieved from a preset component temperature database according to a preset trend period.

[0077] The component temperature database refers to a database that records all previously acquired component temperatures and their acquisition times. The trend period is a pre-set time length used to determine the changing trend of component temperatures. The trend period is generally 12 hours. The historical data is all component temperature values ​​retrieved from the component temperature database according to the trend period.

[0078] Step 307: Determine the temperature change trend based on historical data and obtain the installation location of the air conditioner outdoor unit.

[0079] The change trend refers to the change in component temperature. According to the macro trend of the component temperature, the trend data of the continuous increase or decrease in component temperature is extracted. The identification method of the change trend is selected by the staff according to the actual situation and will not be elaborated here.

[0080] The installation position refers to the coordinate position where the air conditioner outdoor unit is installed. The installation position can be obtained by querying the installation database. The installation database refers to a database that records all air conditioner outdoor units and their corresponding installation positions in advance.

[0081] Step 308: Retrieve meteorological data from a preset meteorological database according to the installation location.

[0082] A meteorological database refers to a database that records data related to weather, such as temperature changes over time in various places, weather conditions, sunrise and sunset times, and sunlight angles. Meteorological data refers to data on temperature changes over time at the installation location the day before retrieved from the meteorological database.

[0083] Step 309: Determine the current time according to the change trend and meteorological data.

[0084] The temperature change trends of two consecutive days at the same location are similar. The current time is the time obtained by comparing the slope of the curve obtained by fitting the data in the change trend with the slope of the curve obtained by fitting the data in the meteorological data. The matching method of the current time is selected by the staff according to the actual situation and will not be elaborated here.

[0085] Step 310: Determine the angle variation parameter of the sunlight irradiation angle according to the current time and the installation location.

[0086] The angle variation parameter refers to the variation data of the sunlight's irradiation angle from the current time to sunset, and the angle variation parameter can be obtained by querying the meteorological database.

[0087] Step 311: Determine the area variation parameter of the irradiation area according to the angle variation parameter and the irradiation area.

[0088] The regional variation parameter refers to the data of the change of the irradiation area over time predicted according to the angle variation parameter. The regional variation parameter can be obtained through the regional variation matching model. The regional variation matching model refers to a neural network model obtained in advance through sample training.

[0089] Step 312: Determine the pole pitch variation parameter according to the area variation parameter.

[0090] The pole distance variation parameter is the data of the change of the irradiation pole distance over time obtained from the regional variation parameter. The identification method of the pole distance variation parameter refers to the identification method of the irradiation pole distance mentioned above.

[0091] Step 313: Control the preset reflective device to expand as the area of ​​the irradiated area changes according to the pole distance variation parameter.

[0092] The changes in the irradiation area are predicted according to the meteorological conditions of the area where the external unit is installed, so as to control the reflective device to change with the changes in the irradiation area, reduce the consumption of computing power, and improve the convenience of using the reflective device.

[0093] Reference Figure 6 , the outdoor unit cooling method also includes: Step 400: Determine the deployment time of the reflective device according to the pole distance variation parameter.

[0094] The expansion time is the length of time that the irradiation pole distance in the pole distance variation parameter is not 0. The identification method of the expansion time is selected by the staff according to the actual situation and will not be elaborated here.

[0095] Step 401: Determine whether there is rainy weather when the reflective device is deployed based on the current time, deployment duration and meteorological data.

[0096] The meteorological database can be queried to determine whether there is precipitation at the installation location during the deployment time from the current time to determine whether there is rainy weather when the reflective device is deployed. The method for determining whether there is rainy weather when the reflective device is deployed is selected by the staff based on actual conditions and will not be elaborated here.

[0097] Step 402: When it is rainy and cloudy when the reflective device is deployed, the high-temperature position on the outer casing of the air conditioner is determined based on the air conditioner components.

[0098] The presence of rainy weather when the reflective device is deployed means that there is no reflective effect for a period of time during the deployment of the reflective device. The high temperature position refers to the position on the outer casing of the air-conditioning outdoor unit that is closest to the air-conditioning components inside the air-conditioning outdoor unit. The high temperature position can be obtained by querying the high temperature position database. The high temperature position database refers to a database that records the high temperature positions corresponding to each air-conditioning component located in the air-conditioning outdoor unit.

[0099] Step 403: Determine the guide area according to the high temperature position.

[0100] The guide area refers to a larger area of ​​the two parts of the top view surface of the air conditioner outdoor unit divided by a line perpendicular to the extension direction of the reflective device and passing through the high temperature position. The guide area can be obtained through a guide area matching model, which refers to a neural network model obtained in advance through sample training.

[0101] Step 404: Determine the rainy period of rainy weather according to the meteorological data.

[0102] The rainy period refers to the time when precipitation is identified from the meteorological data. The matching method of the rainy period is selected by the staff according to the actual situation and will not be elaborated here.

[0103] Step 405: When the current time is in a rainy period, control the preset reflective device to cover the guide area, and raise one end of the reflective device away from the high temperature position.

[0104] When precipitation occurs during the deployment of the reflective device, a precipitation guide surface is formed by the reflective device, so that when the precipitation falls on the reflective device, it flows along the precipitation guide surface to the high-temperature position of the external unit casing, thereby reducing the temperature of the high-temperature position, thereby reducing the temperature of the air-conditioning components in the external unit and improving the stability of the air-conditioning operation.

[0105] Reference Figure 7 , the outdoor unit cooling method also includes: Step 406: When the outdoor unit is illuminated by sunlight, the light intensity of the illuminated area is obtained.

[0106] Light intensity refers to the maximum light intensity value in the irradiated area. The light intensity can be obtained through a light intensity sensor. The method for obtaining the light intensity is selected by the staff according to the actual situation and will not be elaborated here.

[0107] Step 407: When the light intensity exceeds the preset thermal conductivity threshold, the high temperature pole distance is determined according to the high temperature position.

[0108] The thermal conductivity threshold refers to the pre-set minimum value of sunlight intensity at which the temperature of the air conditioner outdoor unit is easily affected by the thermal radiation of the sun. The thermal conductivity threshold is selected by the staff according to the actual situation and will not be elaborated here. When the light intensity exceeds the thermal conductivity threshold, it means that the sunlight is relatively strong at this time, and the degree of thermal radiation of the sunlight is high, which can easily cause the air conditioner outdoor unit to heat up quickly, thereby causing the air conditioner components in the outdoor unit to heat up accordingly. The high temperature pole distance refers to the distance between the high temperature position and the light entrance edge of the outdoor unit, where the light entrance edge of the outdoor unit is set by the staff according to the direction of sunlight. The calculation method of the high temperature pole distance is selected by the staff according to the actual situation and will not be elaborated here.

[0109] Step 408: When the high temperature pole distance is higher than the illumination pole distance, a preset reflective device is controlled to cover the high temperature position according to the high temperature pole distance, and the heat dissipation wind direction of the high temperature position is obtained.

[0110] The high temperature pole distance being higher than the irradiation pole distance means that the reflective device does not cover the high temperature position when covering the irradiation area, and it is necessary to adjust the extension length of the reflective device so that the reflective device covers the high temperature position.

[0111] The heat dissipation wind direction refers to the direction of natural wind at a high temperature position. The heat dissipation wind direction can be obtained through a wind direction sensor. The method for obtaining the heat dissipation wind direction is selected by the staff according to actual conditions and will not be elaborated here.

[0112] Step 409: Based on the fact that the high temperature pole distance is not higher than the illumination pole distance, a preset reflective device is raised according to the heat dissipation wind direction to guide the wind direction.

[0113] The heat dissipation device that increases the heat dissipation wind direction has formed an air guide surface, so that when the natural wind blows through the front end of the air guide surface, it is affected by the air guide surface and blows toward the high-temperature position at the end of the air guide surface, thereby increasing the wind speed at the high-temperature position and improving the heat dissipation efficiency at the high-temperature position, thereby reducing the temperature of the air-conditioning components in the outdoor unit and improving the stability of the air-conditioning operation.

[0114] Reference Figure 8 , the outdoor unit cooling method also includes: Step 410: When the light intensity exceeds a preset thermal conductivity threshold, the heat dissipation wind speed at the high temperature position is obtained.

[0115] The heat dissipation wind speed refers to the wind speed of natural wind at a high temperature position. The heat dissipation wind speed can be obtained through a wind speed sensor. The method for obtaining the heat dissipation wind speed is selected by the staff according to actual conditions and will not be elaborated here.

[0116] Step 411: Determine a corresponding heat dissipation rate according to the ambient temperature and the heat dissipation wind speed.

[0117] The heat dissipation rate is the rate at which the natural wind blowing through the high-temperature position at the ambient temperature and the heat dissipation wind speed carries away the heat. The calculation method of the heat dissipation rate is common knowledge among people in this field and will not be elaborated here.

[0118] Step 412: Determine the air flow rate according to the heat dissipation rate and the temperature difference.

[0119] The wind speed of the airflow passing through the end of the air guide surface can be increased by increasing the air volume introduced into the end of the air guide surface. The air volume refers to the air volume required to reduce the temperature difference to 0 through wind with a heat dissipation rate. The air volume can be obtained by querying the air guide database. The air guide database refers to the air volume required to cool down high-temperature components with different temperature differences through wind with different heat dissipation rates, which is recorded in advance through experiments.

[0120] Step 413: Determine the air guide angle according to the air guide volume and the high temperature pole distance.

[0121] The air volume introduced by the air guide surface can be increased by adjusting the height of the front end of the air guide surface. The lifting height that needs to be adjusted at the front end of the air guide surface can be obtained by querying the air guide height database. The air guide height database refers to a database that records the lifting heights corresponding to different air guide volumes obtained in advance through experiments. The air guide angle is the angle value presented by the reflective device with an extended high-temperature pole distance after being lifted in the heat dissipation wind direction according to the lifting height. The air guide angle can be obtained through an air guide angle matching model. The air guide angle matching model refers to a neural network model obtained in advance through sample training.

[0122] Step 414: Control the preset reflective device to be raised according to the wind guide angle to guide the wind direction.

[0123] By adjusting the height of the heat dissipation wind direction of the reflective device to adjust the air guiding range of the air guiding surface, the speed of the air flow along the air guiding surface through the high-temperature position is adjusted, thereby improving the heat dissipation efficiency of the high-temperature position, reducing the temperature of the air-conditioning components in the outdoor unit, and improving the stability of the air-conditioning operation.
