When the air conditioner is actually operating, it is often affected by different operating environments. The influence of the air conditioner during operation is related to many factors. In related technologies, the operation control of the air conditioner is determined based on the laboratory environment or the national standard working condition. Although the load can be adjusted according to the user's set temperature, the output can be adjusted according to different load requirements. However, it cannot match the dynamic load, user habits and weather parameters in the actual use scenario well, resulting in the unit operation not reaching the best energy-saving performance, and the cooling or heating response speed is slow under some working conditions, or Problems with poor comfort and energy consumption such as excessive output or frequent start and stop.

In view of the above-mentioned problems, no effective solutions have yet been proposed.

Of comfort.

According to the following various embodiments of the present disclosure, the drawbacks of the factory default control mode of the air conditioner can be derived based on historical operating data, which is that the output is too large or the output is insufficient. Later, when the air conditioner is operating under the above-mentioned conditions (including historical weather and regional environment) again, the air conditioner control unit updates the energy-saving control strategy or operating strategy applicable to the air conditioner, so that each air conditioner in the unit is During operation, the control method conforms to the local weather parameters and the size of the area, so as to optimize the use of the air conditioner, improve the energy-saving performance of the unit, and enhance the user's comfort.

Detailed descriptions are given below through various embodiments.

According to an embodiment of the present disclosure, a method for adjusting an operation strategy of an air conditioner is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical sequence is shown in the flowchart, in some cases Below, the steps shown or described can be performed in a different order than here.

Fig. 1 is a flowchart of a method for adjusting an operation strategy of an air conditioner according to some embodiments of the present disclosure. As shown in Figure 1, the method of this embodiment includes the following steps:

Step S102, acquiring historical operating data and historical weather parameters of the air conditioner, where the historical operating data corresponds to the working strategy of the air conditioner;

Step S104, adjusting the working strategy of the air conditioner to the target operation strategy according to the historical operation data;

Step S106, after detecting the current weather parameter, determine the weather parameter difference between the current weather parameter and the historical weather parameter;

Step S108, if it is determined that the weather parameter difference between the current weather parameter and the historical weather parameter is within the preset weather parameter difference range, adjust the current working strategy of the air conditioner as the target operation strategy.

In this embodiment, combining the historical operating data of the air conditioner and historical weather parameters, adaptively adjusting the operating control strategy of the air conditioner can avoid the problems of slow cooling or heating response speed, frequent start and stop, and improve user comfort. And it can reduce the energy consumption of the air conditioner and improve the energy saving of the unit operation. Therefore, the embodiments of the present disclosure can solve the technical problem that the control strategy of the air conditioner in the related art cannot be matched with the actual environment, and the output is prone to abnormalities, frequent startup and shutdown, resulting in poor user comfort and high energy consumption of the air conditioner.

The above steps are described in detail below. In this embodiment, the air conditioner is taken as the main body for description. Of course, the air conditioner can also be understood as an air conditioner unit, an air conditioner controller, etc., which is not limited.

In step S102, the historical operating data and historical weather parameters of the air conditioner are acquired, where the historical operating data corresponds to the working strategy of the air conditioner.

The historical operating data may be data in a historical time period recorded by the control unit of the air conditioner. The historical operating data includes but not limited to: the air conditioner model, the size of the air conditioner working area, the building where the air conditioner is located, and the thermal insulation of the building , The cooling or heating working mode, wind speed, cooling or heating duration of the air conditioner, etc., these data constitute the working strategy of the air conditioner.

In some embodiments of the present disclosure, obtaining historical operating data of an air conditioner includes:

Obtain multiple operating factors, including at least one of the following factors: weather parameters' impact on building load, air conditioner model and air conditioner working area matching degree, and building insulation impact on air conditioner operation Influencing factors

Determine the air conditioner load data and user setting parameters under multiple operating factors. The air conditioner load data is used to determine the output parameters of the air conditioning unit in the air conditioner. The user setting parameters include at least one of the following: Set temperature, set wind speed, set working mode;

Determine historical operating data based on air conditioner load data and user set parameters.

In some embodiments of the present disclosure, the aforementioned user setting parameters further include: user setting humidity, user setting wind mode (such as natural wind mode), and so on.

Through the above-mentioned embodiments, after obtaining the operating load data and user-set parameters of the air conditioner at historical moments, these data can be used as the historical operating data of the air conditioner. For example, if the user sets the parameter to adjust the temperature to 23 degrees Celsius, the historical operating data will record the historical weather outdoor temperature and the target adjusted temperature of 23 degrees Celsius, and then obtain the air conditioner after a period of operation (such as 30 minutes) The parameters of each load of the device and whether the current indoor temperature reaches 23 degrees Celsius. The embodiments of the present disclosure can acquire and record air conditioner load data and user setting parameters in real time.

In some embodiments of the present disclosure, the air conditioner includes at least: a wireless network unit and a control unit, where the control unit is used to control each load module of the air conditioner, and send the target operation strategy to the preset storage module, through the preset The storage module records the historical operating data and target operating strategies of the air conditioner. The air conditioner includes multiple load modules, such as compressors, motors, and electronic expansion valves. During the operation of the air conditioner, the controller unit controls all loads and determines the output of the air conditioner unit according to the current load condition of the air conditioner. The output of the unit is related to the load. There are many ways to determine the load. In the embodiment of the present disclosure, three parameters are set, including: the target temperature set by the user (indicated by T-set), and the current room environment Temperature (represented by T-room), and outdoor ambient temperature (represented by T-outside), load Q=f (T-set, T-room, T-outside).

The wireless network unit is used to obtain current weather parameters and future weather parameters, and transmit the current weather parameters and future weather parameters to the control unit. The wireless network unit may be a GPRS module, or a Bluetooth module, or a WIFI module, etc., and realize data transmission by connecting to the wireless network environment of the area where the air conditioner is located. When acquiring current weather parameters and future weather parameters, the wireless network unit transmits data to the remote server through the mobile network or WIFI network, and the remote server sends the current weather parameters and future weather parameters of the air conditioner to the wireless network unit. Then the wireless network unit sends the data (including current weather parameters and future weather parameters) to the control unit as data for the operation and control of the air conditioner. In some embodiments, the wireless network unit may also be used to obtain historical operating data of the air conditioner.

Weather parameters include but are not limited to: outdoor temperature, humidity, wind speed, rainy, sunny, snowy, sandstorm, etc.

In this disclosure, the impact of weather parameters on the building load will be considered. For example, for temperature, the temperature will directly affect the heat preservation and heat dissipation of the building. For example, when the temperature is high in summer, the temperature of the wall will be increased by direct sunlight or the surrounding air temperature, and this effect will last a long time, usually several hours. Similarly, if it is rainy, the temperature of the wall will be lower. If the air conditioner is controlled and operated in the manner established by the program, the output condition cannot be perfectly matched to the load. Therefore, the embodiment of the present disclosure considers the influence of weather parameters and determines the influence parameters of the air conditioner affected by the weather parameters.

Returning to Fig. 1, in step S104, the operating strategy of the air conditioner is adjusted to the target operating strategy according to the historical operating data.

In the above step S102, the working strategy of the air conditioner obtained according to the historical operating data of the air conditioner may be a more reasonable working strategy that meets the requirements of energy saving and comfort, or may not meet the requirements of energy saving and comfort. , Unreasonable work strategy. In this step S104, the working strategy of the air conditioner is optimized and adjusted according to the historical operation data, so that the working strategy of the air conditioner is adjusted to a target operation strategy that meets the requirements of energy saving and comfort.

In some embodiments of the present disclosure, the step of adjusting the operating strategy of the air conditioner to the target operating strategy according to historical operating data includes:

According to historical operating data, determine whether the output parameters of the air conditioner are abnormal;

If there is no abnormality in the output parameters of the air conditioner, the working strategy of the air conditioner is taken as the target operation strategy;

If the output parameters of the air conditioner are abnormal, determine the influence parameters of the air conditioner during historical operation, and adjust the working strategy to the target operation strategy according to the influence parameters.

In the embodiments of the present disclosure, it is considered that the weather parameter will affect the output of the air conditioner, thereby affecting the cooling or heating effect. The level of the weather parameter will affect the building load, and further affect the air conditioning process of the indoor unit. For example, in an environment of 40°C in summer, the heat transferred to the room through maintenance structures such as walls or windows in the room is different from the heat transferred at 32°C in summer. The heat transfer is different, indicating the magnitude of the building load caused by changes in weather parameters. Also different. At the same time, in the historical operating data, when the weather parameter is a relatively high temperature (such as 40°C) and the indoor temperature set by the user is low (such as 26°C), the indoor unit of the air conditioner is getting closer and closer from turning on and cooling. Set the indoor temperature, and then to stable operation, check the whole process, whether there is a phenomenon that the air conditioner unit frequently runs to the temperature point due to the excessive output of the air conditioner unit, or there is a slow drop in the room temperature due to insufficient output Phenomenon, these phenomena will lead to poor user comfort experience or poor energy saving. By analyzing the control under this historical operating data, we can get a more comfortable and energy-saving control method for the unit when such weather parameters reappear in the future, that is, a new energy-saving operation strategy.

In the embodiments of the present disclosure, in addition to considering the influence of weather parameters on the building load, which will cause the output of the air conditioner to not match the load, the following parameters are also considered: whether the selection of the air conditioner is reasonable (whether the selection is too large or too small), The difference in thermal insulation of buildings in different regions. Record and count the problems of excessive or small output caused by various situations. The recorded data includes not only the state of excessive output or insufficient output, but also other conditions when the problem occurs, such as the weather at the time. Parameters, the current user setting temperature, wind speed, operating time after the air conditioner is turned on, etc.

In some embodiments of the present disclosure, the step of determining the influencing parameter of the air conditioner during historical operation includes: comparing the difference between the user set parameter and the output parameter of the air conditioning unit to determine the influencing parameter. This influencing parameter is the difference between the user set parameter and the output parameter of the air conditioning unit. For example, if the user sets the indoor temperature to 23 degrees Celsius, the initial indoor temperature at that time is 40 degrees Celsius. After adjusting for 30 minutes, it is observed that the indoor temperature still has not decreased. When the temperature reaches 23 degrees Celsius, the output parameters of the air conditioning unit are considered unreasonable, and the output is abnormal.

In some embodiments of the present disclosure, after it is determined that the output parameters of the air conditioner are abnormal, the adjustment method further includes: recording abnormal data through a preset database, wherein the abnormal data includes at least one of the following: Set the output range, the output of the air conditioning unit is higher than the preset output range, the number of starts of the air conditioning unit exceeds the preset number of starts, and the number of shutdowns of the air conditioning unit exceeds the preset number of shutdowns.

The embodiment of the present disclosure considers that weather parameters will affect the output of the air conditioner, thereby affecting the cooling or heating effect. Circumstances with abnormal data include: the output of the unit is too large or the output of the unit is too low. After the user is turned on, if the unit continues to run for t≥T1, but it still cannot reach the set temperature, this situation belongs to the low output of the air conditioning unit. If the unit's continuous operation time t=T2, and the number of starts and stops due to the temperature point of shutdown m≥M1, this situation belongs to the excessive output of the unit. Analyze these operating data of the air conditioner, and then determine the control strategy of the air conditioner. Given weather parameters, user-set parameters and unit output conditions, the unit's operating data can be completely recorded, such as: from the user's startup to stable operation, whether there is cooling or heating during the whole process Slow effects and frequent start and stop problems can all be recorded. Through the detection, recording, comparison, analysis, and query of these data, it is possible to know whether the output is too large or the output is too low.

Returning to Fig. 1, in step S106, after the current weather parameter is detected, the difference between the current weather parameter and the historical weather parameter is determined.

In step S108, if it is determined that the weather parameter difference between the current weather parameter and the historical weather parameter is within the preset weather parameter difference range, the current working strategy of the air conditioner is adjusted as the target operation strategy.

The aforementioned current working strategy includes the setting parameters of the air conditioner at the current moment, for example, the parameters of the compressor operating inside the air conditioner unit, the output cold air of the air conditioner, and the output wind speed.

After adjusting the working strategy to the target operating strategy, the embodiment of the present disclosure adjusts the operating strategy of the air conditioner according to the weather parameter difference between the current weather parameter and the historical weather parameter. If the weather parameter difference is within the preset weather parameter difference range Inside, the working strategy of the air conditioner is adjusted according to the target operation strategy corresponding to the historical weather parameters. That is, after the target operating strategy is updated, the target operating strategy and corresponding historical weather parameters are stored. After receiving the current weather parameters and future weather parameters, it is determined whether there are similar weather parameters in the historical process. The operating parameters of the process are used to adapt the operating strategy of the air conditioner.

In some embodiments of the present disclosure, the adjustment method further includes: after adjusting the operating strategy of the air conditioner to the target operating strategy according to the historical operating data, recording the historical weather parameters and the adjusted target operating strategy.

When the control unit of the air conditioner acquires and records historical weather parameters, the current user setting parameters and the historical operating data of the air conditioner, the drawbacks of the factory default control method of the air conditioner can be obtained (such as excessive output or insufficient output) If the air conditioner runs under the above conditions again, the control unit of the air conditioner updates the energy-saving control strategy applicable to the air conditioner. That is, according to historical operating data, the work strategy can be automatically adjusted to the target operating strategy, so that the operation of the air conditioner is more energy-efficient and the user's comfort in using the air conditioner is improved. For example, if the air conditioner is running in a building with a current outdoor ambient temperature of 40°C, the user sets a cooling temperature of 20°C and runs at a high wind speed. The weather parameters for the past 3 hours and the next 3 hours are air temperature, which are 39°C and 40°C respectively. ℃, 41℃, 40℃, 40℃, 39℃. When the unit continues to run for t≥T1 (for example, T1=40min), but the room does not reach the set temperature, it means that the output of the air conditioner is insufficient in this case, and the user feels poor comfort. In the same way, if during the continuous operation time of the unit t=T2 (for example, T2=30min), there are 8 start and stop times to the temperature point, which is greater than the set start and stop times (for example, M1=2 times), it means The output is too large, and the comfort and energy saving are poor. In view of these situations, the operating strategy of the air conditioner can be adjusted adaptively to make the operation of the air conditioner more energy-efficient and improve the comfort of the user in using the air conditioner.

Through the above-mentioned embodiments, the air conditioner can analyze and judge its own historical operating data, determine a target operating strategy that is compatible with changes in weather parameters, and use the comparative analysis of future weather parameters and historical weather parameters to automatically start the most appropriate operating strategy. The air conditioner can be self-adapted to avoid problems such as slow cooling or heating response speed, frequent startup and shutdown, etc., which improves user comfort and improves the energy-saving performance of the unit.

The present disclosure is illustrated by some other embodiments below.

FIG. 2 is a schematic diagram of a method for adjusting the operation strategy of an air conditioner according to other embodiments of the present disclosure. As shown in FIG. 2, the method in this embodiment includes:

Step S21, the air conditioner control unit detects the air conditioner operating data in real time;

Step S22, the air conditioner control unit judges whether the output of the air conditioner is too large or the output is insufficient according to the detection data;

Step S23, when it is determined that the output of the air conditioner is too large or the output is insufficient, record abnormal data;

Step S24, the air conditioner adaptively adjusts the operating strategy to make it conform to the historically detected weather parameters and the local indoor and outdoor environment; the indoor and outdoor environment includes but is not limited to: the building, the size of the air conditioner's working area, and the insulation of the building;

Step S25, at the current time point, if it is determined that the weather parameters are similar to the historical weather parameters, the current working strategy of the air conditioner is adjusted according to the adjusted operation strategy, so that the air conditioner operating data conforms to the current weather parameters and the current indoor and outdoor environment.

In the above embodiment, given weather parameters, user-set parameters and unit output conditions, the unit's operating data can be completely recorded. For example, from the time the user is turned on until the operation is stable, whether there is a slow cooling or heating effect, and frequent start and stop problems can be recorded during the entire process. By capturing these characteristics, you can know whether there is excessive output. Or insufficient output. The control unit of the air conditioner performs statistics and analysis on the recorded data, and obtains the over output and under output related to weather parameters, user setting status, and unit output conditions of the air conditioner in the determined installation and use environment Relevance. On the basis of this correlation, the corresponding over-output or under-output corrections are made for the output of the air conditioner running in a similar state again, so that the air conditioner's output is more reasonable and matches the load.

After the controller unit of the air conditioner obtains and records historical weather parameters, user-set parameters, and unit operating data, it can be concluded that the factory default control mode of the air conditioner has the disadvantages of excessive output or insufficient output. Then when the air conditioner runs under the above-mentioned conditions again, the controller unit of the air conditioner updates the energy-saving control strategy applicable to the air conditioner, so that the operation of the unit is more energy-efficient and comfortable.
