[0040] 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.

[0041] Refer to Figure 1 , Figure 1 is a schematic structural diagram of an air conditioner in the hardware operating environment related to the embodiment solution of the present invention.

[0042] As Figure 1As shown in the figure, the air conditioner may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, an interaction device 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The interaction device 1003 may include a display screen and an input unit such as a keyboard. Optionally, the interaction device 1003 may also be connected to the communication bus through a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (WI-FI) interface). The memory 1005 may be a high-speed Random Access Memory (RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0043] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the air conditioner, and it may include more or fewer components than shown in the figure, or combine certain components, or have a different component arrangement.

[0044] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a refrigeration unit control program for air circulation analysis.

[0045] In Figure 1 the air conditioner shown in the figure, the network interface 1004 is mainly used for data communication with other devices; the interaction device 1003 is mainly used for data interaction with users; the processor 1001 and the memory 1005 in the air conditioner of the present invention may be arranged in the air conditioner. The air conditioner calls the refrigeration unit control program for air circulation analysis stored in the memory 1005 through the processor 1001 and executes the refrigeration unit control method for air circulation analysis provided by the embodiments of the present invention.

[0046] The embodiments of the present invention provide a refrigeration unit control method for air circulation analysis. Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of a refrigeration unit control method for air circulation analysis of the present invention.

[0047] In this embodiment, it is applied to an air conditioner, and the air conditioner includes: an indoor unit and an outdoor unit. The outdoor unit includes a refrigeration unit. The indoor unit receives the first operation data of the electric doors and windows in the area where it is located. The refrigeration unit control method for air circulation analysis includes the following steps:

[0048] Step S1, obtain the first operation data, the second operation data of the air conditioner, and the indoor environment data where the indoor unit is located. The indoor environment data includes: indoor temperature and indoor carbon dioxide data;

[0049] Here, the first operation data is the data of the opening and closing of the electric window or electric door. Preferably, the control motor of the electric doors and windows is a servo motor. By obtaining the operation data of the servo motor, the opening and closing situation of the electric doors and windows can be determined. That is, the first operation data here can be determined according to the operation data of the servo motor. In addition, further, calculate the corresponding first operation data according to the operation data of the servo motor and the maximum opening and closing area of the electric doors and windows. It should be noted that the electric doors and windows here are connected to the air conditioner. When it is detected that the air conditioner is in the operating state, the first operation data is sent to the air conditioner through the network. The second operation data here can include: operation mode, wind speed, air outlet temperature, etc. In this embodiment, the indoor environment data is detected by corresponding sensors. And the installation position of the sensors is not limited. Preferably, a carbon dioxide sensor is installed on the air conditioner to detect the carbon dioxide data.

[0050] Step S2, determine the air circulation volume data according to the second operation data and the indoor environment data;

[0051] In this embodiment, the air circulation situation is judged by the second operation data and the indoor environment data. For example: judge the specific data of the air circulation volume through the change of temperature and the change of carbon dioxide data. And in the above process, the accuracy of the air circulation volume data is obtained through whether the second operation data is in the fresh air mode and the increase of the refrigeration power, so as to avoid the influence of the functions of the air conditioner itself on the accuracy of the air circulation volume data.

[0052] Step S3, determine the natural ventilation performance of the electric doors and windows according to the air circulation volume data and the first operation data;

[0053] It should be noted that during the process of architectural design, different house type design methods will affect the natural ventilation performance levels of various areas. The relative positions of door and window openings will affect their impact on ventilation. For example: The cross-through type has a wider ventilation coverage area, smooth ventilation, a smaller indoor eddy current area, and good ventilation quality; the staggered type has a wider ventilation coverage area, smooth ventilation, and a smaller indoor eddy current area; for the side-pass type, the outdoor wind speed has little impact on indoor ventilation, and there is very little air disturbance indoors, making it impossible to create good indoor ventilation conditions. Preferably, the natural ventilation performance here is specifically: the ventilation and air change rate. The traditional calculation method is: the ventilation and air change rate of the house type is equal to the average wind speed of the openings on each windward side of the house type multiplied by the effective area of the openings divided by the product of the indoor area and the net height of the house type. Of course, the natural ventilation performance here can also be the air age. However, since the layout of the above building cannot actually be determined during the installation of the air conditioner, in this embodiment, the natural ventilation performance of the electric doors and windows is determined by an indirect calculation method using the air circulation data and the first operation data. Specifically, the natural ventilation performance here is the number of ventilation times per hour increased for each electric unit area.

[0054] Step S4, control the operation of the refrigeration unit according to the natural ventilation performance and the historical control data of the electric doors and windows.

[0055] The natural ventilation performance reflects the efficiency of natural ventilation during the current time period, and predicts the opening situation of the electric doors and windows in the time after the current moment through the historical control data of the electric doors and windows, so that the actual situation of natural ventilation after the current moment can be calculated. For example: For the dining room, during the peak dining period, the electric doors and windows need to be opened frequently, while during the non-peak dining period, the electric doors and windows are in a closed state for a long time, and there will be a large difference in the actual ventilation situation. Under the influence of this difference, the operation of the refrigeration unit can be controlled in a timely manner.

[0056] In this embodiment, the air circulation data is determined through the second operation data and the indoor environment data; the natural ventilation performance of the electric doors and windows is determined according to the air circulation data and the first operation data; compared with the control method of the manual operation mode, controlling the operation of the refrigeration unit according to the natural ventilation performance and the historical control data of the electric doors and windows can effectively change the operation situation of the refrigeration unit based on the natural ventilation situation, avoid the increase in energy consumption caused by simultaneously turning on the fresh air function when the natural ventilation is good, realize the adaptive adjustment of the working mode, and thus overall improve the operation efficiency of the air conditioner as a whole.

[0057] Further, based on the first embodiment, a second embodiment of the control method for the refrigeration unit for air circulation analysis of the present invention is proposed. In this embodiment, refer to Figure 3, the step of determining the air circulation volume data according to the second operation data and the indoor environment data includes:

[0058] Step S21, when the fresh air volume in the second operation data is less than or equal to a preset air volume threshold, determining the air circulation volume data according to the indoor environment data and a first preset mapping relationship;

[0059] Specifically, the fresh air volume here refers to the air supply volume of the fresh air of an air conditioner with a fresh air function. Generally, the requirement for the common fresh air supply volume is that the air supply volume is greater than 20 cubic meters per hour. Therefore, the preset air volume threshold here can be 0 or 20 cubic meters per hour. The specific first preset mapping relationship can be a mapping table of the air circulation volume data and the indoor environment data. Optionally, the first preset mapping relationship can be a table mapping of temperature and carbon dioxide concentration to the air circulation volume data. In addition, when the fresh air mode is not turned on, the fresh air volume here is zero.

[0060] Step S22, when the fresh air volume in the second operation data is greater than the preset air volume threshold, determining the air circulation volume data according to the indoor environment data, the second operation data, and the first preset mapping relationship.

[0061] Specifically, in this embodiment, the second operation data is needed to correct the air circulation volume data. The specific correction method is to subtract the air supply volume of the second operation data from the air circulation volume data determined according to the indoor environment data and the first preset mapping relationship, so as to obtain the corrected air circulation volume data. Of course, in other embodiments, a second mapping relationship can also be constructed, and the second mapping relationship is a mapping table of the indoor environment data, the second operation data, and the air circulation volume data. Thus, the air circulation volume data can be determined during the process of determining the indoor environment data and the second operation data.

[0062] In this embodiment, different calculation methods are used according to different operation modes of the air conditioner, so as to improve the accuracy of determining the air circulation volume data.

[0063] Further, based on the first embodiment or the second embodiment, a third embodiment of the control method for a refrigeration unit for air circulation analysis of the present invention is proposed. In this embodiment, referring to Figure 4 , the step of determining the natural ventilation performance of the electric doors and windows according to the air circulation volume data and the first operation data includes:

[0064] Step S31, classifying the air circulation volume data into first-class air circulation volume data and second-class air circulation volume data according to the door and window opening degree and the corresponding target time;

[0065] In this embodiment, since the opening degree of the doors and windows and the corresponding target time are obtained simultaneously when acquiring the first operation data, the air circulation data can be classified into two types of data corresponding to the doors and windows being open and closed, namely the first type of air circulation data and the second type of air circulation data. In this embodiment, by classifying the air circulation data, it is actually possible to distinguish the influence on the air circulation data under different operating conditions of the electric doors and windows.

[0066] Step S32: Determine the natural ventilation performance according to the first type of air circulation data and the second type of air circulation data.

[0067] Specifically, determine the indoor air circulation data corresponding to the state of the electric doors and windows being open at the current moment according to the first type of air circulation data, and determine the normal indoor air circulation data when the electric doors and windows are closed according to the second type of air circulation data. By synthesizing the above two different indoor air circulation data, the natural ventilation performance can be determined. Specifically, the time corresponding to the first type of air circulation data matches the time when the opening degree of the doors and windows is greater than or equal to the preset opening degree, and the second type of air circulation data is different from the time corresponding to the first type of air circulation data.

[0068] In this embodiment, classifying the air circulation data into the first type of air circulation data and the second type of air circulation data by using the opening degree of the doors and windows and the corresponding target time is actually further confirming the corresponding relationship between the air circulation data and the opening and closing of the indoor doors and windows, effectively clarifying the association between the air circulation data and the opening and closing of the indoor doors and windows in each time period, and helping to improve the accuracy of calculating the natural ventilation performance in the subsequent process.

[0069] Further, the step of determining the natural ventilation performance according to the first type of air circulation data and the second type of air circulation data includes:

[0070] Calculate the difference between two adjacent first type of air circulation data as the first change gradient to obtain a plurality of the first change gradients;

[0071] In this embodiment, taking the difference between two adjacent first type of air circulation data as the first change gradient, the change situation of the air circulation data during the opening process of the electric doors and windows is obtained.

[0072] Calculate the difference between two adjacent second type of air circulation data as the second change gradient, and determine the second average change gradient according to the plurality of the second change gradients;

[0073] In this embodiment, since the electric door and window corresponding to the second change gradient is in a fixed closed state, therefore, for the fixed closed state, the second average change gradient can be determined by calculating a plurality of the second change gradients, so as to accurately calculate the conventional second change gradient in the fixed closed state.

[0074] Determine the natural ventilation performance according to the plurality of the first change gradients and the second average change gradient.

[0075] Optionally, when the electric door and window has only two states of open and closed, the first average change gradient of the plurality of the first change gradients can be calculated. Subtract the second average change gradient from the first average change gradient and multiply by the corresponding conversion weight, where the conversion weight is determined by the area of the opened electric door and window, so as to obtain the natural ventilation performance.

[0076] Optionally, the step of determining the natural ventilation performance according to the plurality of the first change gradients and the second average change gradient includes:

[0077] Calculate the unit change gradient corresponding to each unit of opening according to each of the first change gradients and the corresponding door and window opening degree;

[0078] Specifically, determine the opening area corresponding to each of the first change gradients according to the door and window opening degree and the maximum area of the electric door and window, divide each of the first change gradients by the corresponding opening area, and multiply by the corresponding conversion coefficient to obtain the unit change gradient. Here, the opening area divided by the conversion coefficient is equal to the conversion weight.

[0079] Determine the natural ventilation performance according to the unit change gradient and the second average change gradient.

[0080] Subtract the product of the second average change gradient and the conversion weight from the unit change gradient, so as to obtain the natural ventilation performance. It should be noted that the natural ventilation performance is often affected by the wind force outside the building. In this case, real-time collection of the first operation data, the second operation data of the air conditioner, and the indoor environment data where the indoor unit is located can accurately obtain the change in air circulation caused by the opening and closing of the electric door and window at the current moment.

[0081] In this embodiment, classify the air circulation volume data into the first type of air circulation volume data and the second type of air circulation volume data according to the door and window opening degree and the corresponding target time, and determine the natural ventilation performance according to the first type of air circulation volume data and the second type of air circulation volume data, so as to improve the accuracy of the natural ventilation performance.

[0082] Further, based on any of the above embodiments, a fourth embodiment of the control method for a refrigeration unit in the air circulation analysis of the present invention is proposed. In this embodiment, the historical control data includes: the cumulative duration corresponding to each opening degree of the electric doors and windows in each preset time period. The step of controlling the operation of the refrigeration unit according to the natural ventilation performance and the historical control data of the electric doors and windows includes:

[0083] Step S41, preset the opening data of the electric doors and windows in each time period after the current moment according to the historical control data;

[0084] Optionally, according to the time of the current moment, determine the time of a similar type to the current moment in the historical control data for matching. For example: the time period of each day, whether it is a holiday, etc., and determine the opening data of the electric doors and windows according to the matching result.

[0085] Step S42, predict the predicted air circulation data after the current time according to the opening data and the natural ventilation performance;

[0086] Specifically, multiply the opening data of each time period by the natural ventilation performance respectively to obtain the predicted air circulation data corresponding to each time period.

[0087] Step S43, adjust the operation parameters of the refrigeration unit according to the predicted air circulation data, and control the operation of the refrigeration unit according to the operation parameters.

[0088] Specifically, when the predicted air circulation data is greater than the preset circulation data, turn off the fresh air function of the air conditioner, and at the same time increase the operation power of the refrigeration unit. When the predicted air circulation data is less than or equal to the preset circulation data, turn on the fresh air function of the air conditioner, and at the same time reduce the operation power of the refrigeration unit.

[0089] Further, the step of obtaining the first operation data, the second operation data of the air conditioner, and the indoor environment data where the indoor unit is located includes:

[0090] Receive the first operation data of the electric doors and windows according to a preset frequency, and obtain the second operation data while receiving the first operation data, and detect the indoor environment data.

[0091] In this embodiment, the first operation data, the second operation data of the air conditioner, and the indoor environment data where the indoor unit is located are obtained at the same time, thus ensuring the relevance between the data, and thus being able to determine the accuracy of the predicted air circulation data.
