[0046] The embodiment of the present invention provides a refrigeration unit control method for air circulation analysis, referring to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a refrigeration unit control method for air circulation analysis according to the present invention.

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

[0048] Step S1, obtaining first operating data, second operating data of the air conditioner, and indoor environment data of the indoor unit, wherein the indoor environment data includes indoor temperature and indoor carbon dioxide data;

[0049] The first operating data here refers to the data on the opening and closing of electric windows or electric doors. Preferably, the control motor of the electric windows and doors is a servo motor. By obtaining the operating data of the servo motor, the opening and closing conditions of the electric windows and doors can be determined, that is, the first operating data here can be determined based on the operating data of the servo motor. In addition, the corresponding first operating data is calculated based on the operating data of the servo motor and the maximum opening and closing area of ​​the electric windows and doors. It should be noted that the electric windows and doors here are connected to the air conditioner. When it is detected that the air conditioner is in operation, the first operating data is sent to the air conditioner via the network. The second operating data here may include: operating mode, wind speed, air outlet temperature, etc. In this embodiment, the indoor environment data is obtained by detecting the corresponding sensor. The setting location of the sensor is not limited. Preferably, a carbon dioxide sensor is set on the air conditioner to detect the carbon dioxide data.

[0050] Step S2, determining air circulation data according to the second operating data and the indoor environment data;

[0051] In this embodiment, the air circulation condition is determined based on the second operating data and the indoor environment data. For example, specific data on air circulation volume is determined based on changes in temperature and carbon dioxide data. The accuracy of the air circulation volume data obtained in this process is enhanced by determining whether the second operating data indicates fresh air mode and the cooling power, thereby preventing the air circulation volume data from being affected by the air conditioner's inherent functions.

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

[0053] It should be noted that during the architectural design process, different apartment designs can affect the natural ventilation performance level of each area. The relative position of door and window openings can influence their impact on ventilation. For example, through-the-hall designs offer wider ventilation coverage, smoother ventilation, smaller indoor vortex zones, and better ventilation quality; staggered designs offer wider ventilation coverage, smoother ventilation, and smaller indoor vortex zones; and side-by-side designs have little impact on indoor ventilation due to outdoor wind speed, resulting in minimal indoor air disturbance and inability to create good indoor ventilation conditions. Preferably, the natural ventilation performance here is specifically defined as the number of air changes. The traditional calculation method is: the number of air changes for an apartment is equal to the average wind speed of each opening on the windward side of the apartment multiplied by the effective area of ​​the opening divided by the product of the apartment's floor area and net height. Natural ventilation performance can also be defined as air age. However, since the building layout cannot be determined during air conditioner installation, in this embodiment, the natural ventilation performance of electric doors and windows is determined indirectly through the air flow data and the first operating data. Specifically, the natural ventilation performance here is the number of air changes per hour added per unit area of ​​electric doors and windows.

[0054] Step S4: controlling 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. The actual natural ventilation situation after the current time period is calculated by predicting the opening status of the electric doors and windows based on the historical control data of the electric doors and windows. For example, during peak dining hours in a restaurant, the electric doors and windows need to be opened frequently, while during non-peak dining hours, the electric doors and windows remain closed for extended periods. This significant difference in actual ventilation conditions can be used to timely control the operation of the refrigeration unit.

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

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

[0058] Step S21: when the fresh air volume in the second operating 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 fresh air supply volume of an air conditioner with a fresh air function. Common fresh air supply volume requirements are generally greater than 20 cubic meters per hour. Therefore, the preset air volume threshold here can be 0 or 20 cubic meters per hour. The first preset mapping relationship here can specifically 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 temperature and carbon dioxide concentration to air circulation volume data. In addition, when the fresh air mode is not enabled, the fresh air volume here is zero.

[0060] Step S22: When the fresh air volume in the second operating data is greater than a preset air volume threshold, the air circulation volume data is determined according to the indoor environment data, the second operating data, and a first preset mapping relationship.

[0061] Specifically, in this embodiment, the second operating data is used to correct the air circulation data. The specific correction method is to determine the air circulation data based on the indoor environment data and a first preset mapping relationship, and then subtract the air supply volume of the second operating data, thereby obtaining the corrected air circulation data. Of course, in other embodiments, a second mapping relationship can also be constructed, where the second mapping relationship is a mapping table of the indoor environment data, the second operating data, and the air circulation data. Thus, the air circulation data can be determined during the process of determining the indoor environment data and the second operating data.

[0062] In this embodiment, different calculation methods are used according to different operating modes of the air conditioner, thereby improving the accuracy of the data for determining the air flow rate.

[0063] Further, based on the first embodiment or the second embodiment, a third embodiment of the refrigeration unit control method 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 flow data and the first operating data includes:

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

[0065] In this embodiment, since the door and window openings and the corresponding target times are obtained simultaneously with the first operating data, the air circulation data can be categorized into two types: first-category air circulation data and second-category air circulation data, corresponding to doors and windows open and closed. In this embodiment, by categorizing the air circulation data, it is possible to distinguish the impact of different electric door and window operating conditions on the air circulation data.

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

[0067] Specifically, the first type of air circulation data is used to determine the indoor air circulation data corresponding to the currently open power doors and windows. The second type of air circulation data is used to determine the normal indoor air circulation data when the power doors and windows are closed. By combining these two different types of 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 corresponding to when the door and window opening is greater than or equal to a preset opening, while the time corresponding to 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, the air circulation data is classified into first-category air circulation data and second-category air circulation data using the door and window openings and the corresponding target time. This actually further confirms the correspondence between the air circulation data and the opening and closing of indoor doors and windows, and can effectively clarify the correlation between the air circulation data and the opening and closing of indoor doors and windows in each time period, and help to improve the accuracy of subsequent calculations of natural ventilation performance.

[0069] Furthermore, 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] calculating a difference between two pieces of the first-type air circulation data at adjacent times as a first change gradient, and obtaining a plurality of the first change gradients;

[0071] In this embodiment, the difference between two adjacent first-category air circulation data is used as the first change gradient to obtain the change of the air circulation data during the opening process of the electric door and window.

[0072] calculating a difference between two pieces of second-category air circulation data at adjacent times as a second change gradient, and determining a second average change gradient based on a 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, for the fixed closed state, the second average change gradient can be determined by calculating multiple second change gradients, thereby improving the accuracy of calculating the conventional second change gradient in the fixed closed state.

[0074] The natural ventilation performance is determined according to a plurality of the first change gradients and the second average change gradient.

[0075] Optionally, when the power door and window have only two states, open and closed, a first average change gradient of a plurality of first change gradients may be calculated. The first average change gradient is subtracted from the second average change gradient, and the resultant value is multiplied by a corresponding conversion weight determined by the area of ​​the open power door and window, thereby obtaining the natural ventilation performance.

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

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

[0078] Specifically, the opening area corresponding to each first change gradient is determined based on the door and window opening and the maximum area of ​​the electric door and window. Each first change gradient is divided by the corresponding opening area and multiplied by the corresponding conversion coefficient to obtain a unit change gradient. Here, the opening area divided by the conversion coefficient equals the conversion weight.

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

[0080] The natural ventilation performance is obtained by subtracting the product of the second average change gradient and the conversion weight from the unit change gradient. It should be noted that the natural ventilation performance here is often affected by the wind speed outside the building. In this case, real-time acquisition of the first operating data, the second operating data of the air conditioner, and the indoor environment data where the indoor unit is located can accurately obtain the current changes in air circulation caused by the opening and closing of electric doors and windows.

[0081] In this embodiment, the air circulation data is classified into first-category air circulation data and second-category air circulation data according to the door and window openings and the corresponding target time, and the natural ventilation performance is determined based on the first-category air circulation data and the second-category air circulation data, thereby improving the accuracy of the natural ventilation performance.

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

[0083] Step S41, presetting 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 current time, a time type similar to the current time in the historical control data is determined for matching, such as: daily time period, whether it is a holiday, etc., and the opening data of the electric doors and windows is determined according to the matching results.

[0085] Step S42, predicting air circulation data after the current time based on the opening data and the natural ventilation performance;

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

[0087] Step S43: adjusting the operating parameters of the refrigeration unit according to the predicted air circulation data, and controlling the operation of the refrigeration unit according to the operating parameters.

[0088] Specifically, when the predicted air circulation data is greater than the preset circulation data, the fresh air function of the air conditioner is turned off and the operating power of the refrigeration unit is increased. When the predicted air circulation data is less than or equal to the preset circulation data, the fresh air function of the air conditioner is turned on and the operating power of the refrigeration unit is reduced.

[0089] Furthermore, the step of obtaining the first operating data, the second operating data of the air conditioner, and the indoor environment data of the indoor unit includes:

[0090] The first operation data of the electric door and window is received according to a preset frequency, and the second operation data is acquired while the first operation data is received, and the indoor environment data is detected.

[0091] In this embodiment, the first operating data, the second operating data of the air conditioner, and the indoor environment data of the indoor unit are obtained at the same time, thereby ensuring the correlation between the data and determining the accuracy of the predicted air circulation data.

[0092] In addition, an embodiment of the present invention further proposes a refrigeration unit control system for air circulation analysis, which is applied to an air conditioner, the air conditioner comprising: an indoor unit and an outdoor unit, the outdoor unit comprising a refrigeration unit, the indoor unit receiving first operating data of electric doors and windows in the area in which it is located, and the refrigeration unit control system for air circulation analysis comprising: an acquisition module for acquiring the first operating data, second operating data of the air conditioner, and indoor environment data where the indoor unit is located, the indoor environment data comprising indoor temperature and indoor carbon dioxide data; an analysis module for determining air circulation volume data based on the second operating data and the indoor environment data; a weighting module for determining the natural ventilation performance of the electric doors and windows based on the air circulation volume data and the first operating data; and a control module for controlling the operation of the refrigeration unit based on the natural ventilation performance and historical control data of the electric doors and windows.
