[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] The automatic air conditioning adjustment method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or located in the cloud or on other network servers. Terminal 102 generates an automatic air conditioning adjustment request and then sends this request to server 104, so that server 104 can automatically adjust the air conditioning. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. Portable wearable devices can include smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0050] In one embodiment, such as Figure 2As shown, the air conditioning system includes air conditioners 202, smart sockets 204, cloud platform modules 206, and terminals including smartphones 216, PCs 218, and a management center 220. The smart socket 204 includes an infrared monitoring module 208, a temperature monitoring module 210, a power monitoring module 212, and a Wi-Fi module 214. These modules are integrated into the smart socket 204. Through the coordinated operation of these modules, the system connects them via a circuit to the smart socket 204. This allows for monitoring of multiple air conditioners 202. 02. The system achieves infrared monitoring, temperature monitoring, power detection, and WIFI remote control. By plugging multiple air conditioners 202 into different smart sockets 204, the circuit connection of multiple air conditioner devices can be effectively completed. At the same time, it can also achieve real-time monitoring. The real-time data of the four modules, namely infrared monitoring module 208, temperature monitoring module 210, power detection module 212 and WIFI module 214, are directly transmitted to cloud platform module 206. After fusion and processing, the real-time data of multiple air conditioners 202 is generated in cloud platform module 206, and remote control can be achieved through smartphone 216, management center 220 and PC terminal 218.

[0051] In one embodiment, such as Figure 3 As shown, an automatic air conditioning adjustment method is provided, which is applied to... Figure 1 Taking 104 as an example, the explanation includes the following steps:

[0052] Step 302: Detect the indoor carbon dioxide concentration to obtain the carbon dioxide concentration result, and determine the target air volume required for the indoor air volume in the future preset time period based on the carbon dioxide concentration result.

[0053] The specific methods for detecting indoor carbon dioxide concentration are not limited. Infrared sensors can be used to detect the absorption characteristics of carbon dioxide molecules through infrared radiation. Carbon dioxide molecules have a high absorption rate for infrared radiation of specific wavelengths, and the sensor detects the concentration of carbon dioxide by measuring the amount of absorbed infrared radiation. Electrochemical sensors can also be used to detect carbon dioxide concentration by measuring changes in current or potential. This type of sensor uses the changes in current or potential generated by the chemical reaction between the carbon dioxide-containing gas and the electrode to measure the concentration. Alternatively, optical sensors can be used to detect concentration by the absorption characteristics of carbon dioxide molecules for light of specific wavelengths. This type of sensor indirectly measures the concentration of carbon dioxide by measuring changes in the intensity of transmitted or reflected light. Understandably, these sensors can be integrated with air conditioning systems or air quality monitoring systems to monitor indoor carbon dioxide concentration in real time and adjust the operating mode of the air conditioning system as needed to maintain a comfortable and safe level of indoor air quality.

[0054] Specifically, refer to Figure 2 The absorption characteristics of carbon dioxide molecules are detected by the infrared monitoring module 208. Carbon dioxide molecules have a high absorption rate for infrared radiation of a specific wavelength. The sensor detects the concentration of carbon dioxide by measuring the amount of absorbed infrared radiation. After obtaining the indoor carbon dioxide concentration result, the result is compared with the ideal carbon dioxide concentration to obtain the difference between the two. Based on this difference, the air volume required to adjust the current indoor carbon dioxide concentration to the ideal carbon dioxide concentration is calculated, which is the target air volume.

[0055] Step 304: Determine the indoor dew point temperature based on the current indoor temperature, and determine the target air outlet temperature based on the dew point temperature. Set the air outlet temperature of the air conditioner to the target air outlet temperature.

[0056] The dew point temperature is the temperature at which air condenses into dew under a certain pressure. When air is cooled to its saturation point (containing water vapor), the water vapor begins to condense into small water droplets and form dew. This temperature is the dew point temperature. (Reference) Figure 2 The air outlet temperature of air conditioner 202 varies depending on the air conditioner's settings and operating mode. While the air outlet temperature is set based on the dew point temperature, this application does not limit the specific setting.

[0057] Specifically, the current indoor temperature is detected, and the current indoor dew point temperature is calculated based on this temperature. The air conditioner's airflow speed is then set with reference to this dew point temperature.

[0058] In one example, the current indoor temperature is detected, and the current indoor dew point temperature is calculated based on this temperature. The air conditioner's airflow speed is then set to this dew point temperature.

[0059] In another example, the current indoor temperature is detected, and the current indoor dew point temperature is calculated based on that temperature. The air conditioner's airflow speed is then set to a temperature value near that dew point temperature, with reference to that dew point temperature.

[0060] Optional, see reference Figure 2 The dew point temperature of the air is obtained by calculating data through the temperature monitoring module 210. This temperature is then used to adjust the opening of the condenser valve and expansion valve in the air conditioner. By changing the opening of the two valves, the dew point temperature can be controlled. The air outlet temperature of the air conditioner can be flexibly and freely controlled, which can balance the indoor temperature and humidity and effectively prevent condensation from occurring in the air when the humidity is too high.

[0061] Step 306: Based on the temperature difference between the current indoor temperature and the outdoor temperature, determine the target number of air changes to meet the low air change conditions, and set the air change rate of the air conditioner as the target number of air changes.

[0062] The air exchange rate of an air conditioner refers to the number of times an air conditioning system can completely replace indoor air per hour. The air exchange rate depends on the ventilation capacity of the air conditioning equipment and the operating environment. Understandably, the temperature difference between indoors and outdoors is the most significant factor affecting the air exchange rate. When the temperature difference is large, the air conditioning system will start frequently to exchange heat and maintain a stable indoor temperature. Conversely, if the temperature difference is small, the air exchange rate may be relatively low because the indoor temperature is easier to maintain within a comfortable range. Furthermore, the air exchange rate has a certain impact on energy consumption. A higher air exchange rate means the air conditioning system needs to process fresh air more frequently, thus increasing energy consumption. Therefore, it is necessary to determine an air exchange rate that minimizes the energy consumption of the air conditioner.

[0063] Specifically, refer to Figure 2 The power detection module 212 monitors the energy consumption and analyzes the impact of air exchange rate on energy consumption based on the different air environments in the intelligent computer room and outdoors. The air exchange rate should be specified within a certain range to ensure that the energy consumption of the entire intelligent computer room system is minimized. On the basis of using high-quality air and meeting the indoor air quality index, the low air exchange rate n is found. The control frequency of each part of the intelligent computer room system should be above the low control frequency, that is, the air volume should meet the requirements of the low control index.

[0064] Step 308: Determine the correspondence between the air conditioner's energy consumption, air outlet frequency, and air outlet speed based on the target air exchange rate and target air outlet temperature.

[0065] The air outlet frequency of an air conditioner refers to the number of times the air conditioning system delivers air into the room per minute. The air outlet velocity refers to the speed at which the air conditioning system delivers air into the room. Understandably, the air outlet frequency and velocity can be set according to indoor needs. The air volume of an air conditioner can be calculated by multiplying its air outlet frequency and velocity. With the same air volume, different air outlet velocities and frequencies may result in different energy consumption. Generally, lower air outlet velocities and frequencies reduce the energy consumption of the air conditioning system. Lower air outlet velocities reduce airflow dynamics, lower wind resistance, and reduce fan power consumption. Lower air outlet frequencies also reduce the operating time of the air conditioning system, thereby reducing energy consumption.

[0066] Specifically, refer to Figure 2 Through the cloud platform module 206, based on a low air exchange rate n and a fixed target air outlet temperature, detailed data analysis is performed on the air conditioner's energy consumption, air outlet frequency, and air outlet speed. The data is compared and calculated through the cloud platform, and analyzed and processed through the information fusion module and information processing module, ultimately constructing the correspondence between the air conditioner's energy consumption, air outlet frequency, and air outlet speed.

[0067] Step 310: Based on the correspondence, determine the target air outlet frequency and the target air outlet speed, and set the air outlet frequency of the air conditioner to the target air outlet frequency and the air outlet speed of the air conditioner to the target air outlet speed.

[0068] The correspondence specifically refers to the relationship between air conditioner energy consumption, air outlet frequency, and air outlet speed. Since the target air volume required indoors during a preset future period is fixed, and this target air volume determines the air conditioner's air outlet volume, the air outlet volume can be calculated by multiplying the air outlet frequency and air outlet speed. Therefore, with the same air outlet volume, different air outlet frequencies and speeds can be set, but different air outlet speeds and frequencies may result in different energy consumption. Each set of air conditioner air outlet speed and frequency corresponds to a specific air conditioner energy consumption; this correspondence is the relationship between air conditioner energy consumption, air outlet frequency, and air outlet speed.

[0069] Specifically, firstly, based on the target air volume required indoors during a preset future time period, the air volume of the air conditioner is determined. Then, based on the air volume, the air outlet speed and frequency of each air conditioner group are determined. Since the energy consumption of each air conditioner group varies depending on its air outlet speed and frequency, the air outlet frequency and speed at which the energy consumption is specific are determined based on the energy consumption corresponding to each air outlet speed and frequency. At this point, the air outlet frequency of the air conditioner is the target air outlet frequency, and the air outlet speed is the target air outlet speed.

[0070] In one embodiment, the saturated water vapor pressure in the room is determined based on the current indoor temperature; the actual water vapor pressure in the room is detected, and the relative humidity in the room is determined based on the ratio between the actual water vapor pressure and the saturated water vapor pressure; the dew point temperature in the room is determined based on the current indoor temperature and relative humidity; the dew point temperature is used as the target outlet air temperature, and the opening of the condenser valve and expansion valve in the air conditioner are adjusted respectively to make the outlet air temperature of the air conditioner the target outlet air temperature.

[0071] In air conditioning systems, the opening degree of the two valves refers to the condenser valve and the expansion valve. The condenser valve primarily regulates the pressure and flow rate of refrigerant in the condenser. By adjusting the opening degree of the condenser valve, the cooling effect of the refrigerant in the condenser can be controlled, thus affecting the cooling capacity and outlet air temperature of the air conditioning system. The expansion valve is another important component of the air conditioning system, mainly used to control the flow rate of refrigerant in the evaporator. By adjusting the opening degree of the expansion valve, the flow rate and evaporation effect of the refrigerant in the evaporator can be controlled, thus affecting the cooling capacity and outlet air temperature of the air conditioning system. By adjusting the opening degrees of the condenser valve and expansion valve in the air conditioning system, the outlet air temperature can be flexibly adjusted, thereby affecting the dew point temperature and humidity in the air. This allows for balanced regulation of air humidity and temperature, preventing condensation caused by excessive humidity.

[0072] Specifically, dew point temperature refers to the temperature at which water vapor in the air becomes liquid under constant pressure. It is determined by both the relative humidity and temperature of the air. Calculating dew point temperature requires knowing the relative humidity and temperature of the air. Assume the relative humidity is RH (expressed as a percentage, e.g., 50% means 50% relative humidity) and the temperature is T (expressed in degrees Celsius or Fahrenheit). The dew point temperature is calculated using the formula: Td = T - ((100 - RH) / 5). Where Td represents the dew point temperature, T represents the actual temperature, and RH represents the relative humidity. The calculated dew point temperature is in degrees Celsius. After calculating the indoor dew point temperature, the degree to which the valves in the condenser and expansion valves of the air conditioning system are opened or closed is adjusted based on this dew point temperature to set the air conditioner's outlet air temperature to the target outlet air temperature. Understandably, this target outlet air temperature setting is based on the calculated dew point temperature. Optionally, the air conditioner's outlet air temperature can be set to the dew point temperature.

[0073] Since dew point temperature represents the relative humidity of the air, it is the temperature at which the moisture in the air begins to condense. Therefore, adjusting the air conditioner's outlet temperature according to the indoor dew point temperature can ensure that the relative humidity of the indoor air is within a comfortable range, avoiding excessive dryness or humidity and providing a more comfortable indoor environment. Maintaining a dry indoor environment reduces the possibility of mold growth. Furthermore, setting the air conditioner's outlet temperature reasonably according to the dew point temperature can avoid over-cooling or over-heating, achieving energy-saving effects and reducing energy consumption and operating costs.

[0074] In one embodiment, a matching air exchange rate is selected based on the temperature difference between the current indoor temperature and the outdoor temperature; the minimum number of air exchanges of the air conditioner is determined based on the air exchange rate, and the minimum number of air exchanges is used as the target number of air exchanges; the number of air exchanges of the air conditioner is set as the target number of air exchanges.

[0075] The air exchange rate refers to the rate at which air is renewed in an air conditioning system, that is, the amount of fresh air entering or leaving the indoor space per hour. The air exchange rate directly affects indoor air quality and comfort. Simply put, the air exchange rate of an air conditioning system refers to the frequency with which the air conditioner starts, that is, the number of times the air conditioner starts per unit of time. The air exchange rate, on the other hand, refers to the number of times air is circulated and processed per unit of time. There is a certain relationship between the air exchange rate and the air exchange rate. Generally, the higher the air exchange rate, the higher the air exchange rate of the air conditioning system will be.

[0076] Specifically, based on indoor building codes and relevant standards, find the guideline values ​​related to air exchange rate. These standards typically provide a certain temperature difference range and corresponding air exchange rate requirements. Compare the temperature difference with the temperature difference range in the air exchange rate standard. If the temperature difference is within the standard range, the standard air exchange rate can be selected. If the temperature difference exceeds the standard range, the air exchange rate needs to be increased or decreased accordingly, depending on the extent of the exceedance. Select the appropriate air exchange rate scheme based on the determined temperature difference range. If the temperature difference is small, a lower air exchange rate can be selected to save energy. If the temperature difference is large, a higher air exchange rate needs to be selected to maintain indoor air quality and comfort. Then, after selecting a good air exchange rate, determine the minimum air exchange rate of the air conditioner, use this minimum air exchange rate as the target air exchange rate, and set the air conditioner's air exchange rate to this target air exchange rate.

[0077] By determining the appropriate air exchange rate based on the temperature difference between indoors and outdoors, and then determining the minimum number of air exchanges based on the air exchange rate, the impact of the number of air exchanges on air conditioning energy consumption can be analyzed based on the different indoor and outdoor air environments. Then, the number of air exchanges can be specified within a certain range to ensure that the energy consumption of the entire intelligent computer room system is minimized as much as possible.

[0078] In one embodiment, the temperature difference between the current indoor temperature and the outdoor temperature is determined, and the ratio between the temperature difference and the air exchange rate is determined, and the ratio between the temperature difference and the air exchange rate is used as the minimum number of air exchanges; or, the indoor air is detected according to a preset air quality index to obtain an indoor air quality index; the indoor air quality index and the preset air quality index are combined to determine the air exchange demand value; the ratio between the air exchange demand value and the air exchange rate is determined, and the ratio between the air exchange demand value and the air exchange rate is used as the minimum number of air exchanges.

[0079] In one example, the calculation of indoor air quality requirements involves the following steps: First, the indoor air quality requirements, i.e., the preset air quality indicators, need to be determined. Generally, indoor air quality requirements can be characterized by one of the following indicators: for example, a carbon dioxide concentration of 600 ppm (used to represent the concentration of a substance in a whole). Then, based on the indoor air quality requirements and the measurement results of indoor air quality, the actual ventilation requirement is calculated. Finally, the minimum ventilation rate is calculated using the formula: Minimum ventilation rate = Ventilation requirement / Ventilation rate.

[0080] In another example, the calculation based on the indoor-outdoor temperature difference and ventilation rate involves the following steps: First, the indoor-outdoor temperature difference needs to be determined. Then, based on this temperature difference and considering the characteristics of the building structure and materials, an appropriate ventilation rate is selected. Finally, the minimum ventilation rate is calculated using the formula: Minimum ventilation rate = Indoor-outdoor temperature difference / Ventilation rate.

[0081] By calculating based on indoor air quality requirements and indoor-outdoor temperature difference and air exchange rate, the minimum air exchange rate of the air conditioning system can be calculated. This allows for reasonable calculation and control of the minimum air exchange rate, which can improve indoor air quality, reduce the accumulation of indoor pollutants, save energy and reduce costs, and provide a more comfortable indoor environment.

[0082] In one embodiment, based on the surface, the air outlet frequency and air outlet speed corresponding to the lowest energy consumption of the air conditioner are determined, and the air outlet frequency corresponding to the lowest energy consumption of the air conditioner is taken as the target air outlet frequency, and the air outlet speed corresponding to the lowest energy consumption of the air conditioner is taken as the target air outlet speed.

[0083] Specifically, refer to Figure 4 Based on the air conditioner's energy consumption, air outlet frequency, and air outlet speed, a graphical analysis is performed. The horizontal axis 406 of the three-dimensional Cartesian coordinate system represents the air outlet frequency, the vertical axis 408 represents the air outlet speed, and the vertical axis 410 represents the energy consumption. By varying different air outlet parameters (air outlet speed and air outlet frequency) and recording the corresponding energy consumption data, a series of data points are obtained. Finally, connecting these data points or plotting them as a scatter plot yields a surface 402 depicting the relationship between air conditioner energy consumption and different air outlet parameters (air outlet speed and air outlet frequency). Further, based on the positional relationships of different coordinate points on the surface, the air outlet speed corresponding to the lowest energy consumption is determined as the target air outlet speed, and the air outlet frequency corresponding to the lowest energy consumption is determined as the target air outlet frequency.

[0084] Because the air conditioning's airflow frequency and speed can be adjusted to achieve the lowest energy consumption, maximum comfort and energy efficiency are provided when these parameters are matched to the required indoor airflow conditions. Setting target airflow frequencies and speeds avoids energy waste and improves energy efficiency, thereby reducing air conditioning operating costs. Furthermore, determining the target airflow speed and frequency by plotting surfaces makes the entire process visible, facilitating deeper analysis of relevant parameters and data, enabling more in-depth processing and analysis, and improving the accuracy and efficiency of decision-making.

[0085] In one embodiment, the coordinate point with the minimum air conditioner energy consumption is determined in the curved surface. The horizontal coordinate of the coordinate point with the minimum air conditioner energy consumption is the air outlet frequency corresponding to the minimum energy consumption of the air conditioner; the vertical coordinate of the coordinate point with the minimum air conditioner energy consumption is the air outlet speed corresponding to the minimum energy consumption of the air conditioner.

[0086] Specifically, refer to Figure 4Since the vertical axis of the three-dimensional Cartesian coordinate system is used to represent the energy consumption of the air conditioner, it is only necessary to find the coordinate point 404 with the smallest vertical coordinate value on the surface, then take the horizontal coordinate value corresponding to this coordinate point as the target air outlet frequency, and take the vertical coordinate value corresponding to this coordinate point as the target air outlet velocity. It is understandable that in this application, the method for determining the minimum energy consumption mainly refers to the vertical coordinate; the coordinate point with the smallest vertical coordinate value is selected from the coordinate points on the surface, and the corresponding horizontal and vertical coordinate values ​​are the target air outlet frequency and target air outlet velocity. However, either the horizontal or vertical coordinate value can be used as the target air outlet frequency or the target air outlet velocity. In other words, there are two forms of the three-dimensional Cartesian coordinate system. In the first form, the horizontal axis of the three-dimensional Cartesian coordinate system is used to represent the air outlet frequency of the air conditioner, the vertical axis is used to represent the air outlet speed of the air conditioner, and the vertical axis is used to represent the energy consumption of the air conditioner. In the second form, the horizontal axis of the three-dimensional Cartesian coordinate system is used to represent the air outlet speed of the air conditioner, the vertical axis is used to represent the air outlet frequency of the air conditioner, and the vertical axis is used to represent the energy consumption of the air conditioner.

[0087] By using surface plotting to find the target air velocity and frequency, the data is displayed in three dimensions. Visualization allows for an intuitive view of the surface's shape and characteristics, and the location of the minimum vertical coordinate value can be identified. This makes it easy to find the coordinates corresponding to the minimum vertical coordinate value, avoiding tedious calculations in multidimensional data. Furthermore, finding the target air velocity and frequency through surface plotting allows for a more accurate determination of the optimal solution. Especially in multidimensional data, where the minimum point may exist in various dimensions and combinations, surface plotting provides a clear view of the minimum point's location and advantages. Particularly since the target rotation speed and target air temperature can change, if multiple strategies or parameters can be adjusted, surface plotting allows for comparison of the position and value of the minimum vertical coordinate under different strategies, thus better evaluating and comparing the effectiveness of different strategies. This helps in finding the optimal strategy or parameter settings, improving decision-making efficiency.

[0088] In one embodiment, reference Figure 2 Remote control and adjustment can be achieved through terminals including smartphones 216, PCs 218, and management centers 220. In the process of intelligent adjustment indoors, the most energy-efficient regulation can also be achieved.

[0089] In one embodiment, such as Figure 5 As shown, Figure 5 The following is a flowchart illustrating an automatic air conditioning adjustment method in another embodiment, including the following steps:

[0090] Step 502: Detect the indoor carbon dioxide concentration, obtain the carbon dioxide concentration result, and determine the target air volume required indoors in the future preset time period based on the carbon dioxide concentration result.

[0091] Step 504: Determine the indoor saturated water vapor pressure based on the current indoor temperature; detect the actual indoor water vapor pressure, and determine the indoor relative humidity based on the ratio between the actual water vapor pressure and the saturated water vapor pressure; determine the indoor dew point temperature based on the current indoor temperature and relative humidity; use the dew point temperature as the target outlet air temperature, and adjust the opening of the condenser valve and expansion valve in the air conditioner respectively so that the outlet air temperature of the air conditioner is the target outlet air temperature.

[0092] Step 506: Select a matching air exchange rate based on the temperature difference between the current indoor temperature and the outdoor temperature; determine the minimum air exchange rate of the air conditioner based on the air exchange rate, and set the minimum air exchange rate as the target air exchange rate; set the air exchange rate of the air conditioner as the target air exchange rate.

[0093] Step 508: Based on the target air exchange rate and the target air outlet temperature, plot the surface relating the air conditioner's energy consumption, air outlet frequency, and air outlet speed in a three-dimensional Cartesian coordinate system.

[0094] Step 510: Determine the coordinate point with the minimum air conditioner energy consumption in the curved surface. The horizontal coordinate of the coordinate point with the minimum air conditioner energy consumption is the air outlet frequency corresponding to the minimum energy consumption of the air conditioner. The vertical coordinate of the coordinate point with the minimum air conditioner energy consumption is the air outlet speed corresponding to the minimum energy consumption of the air conditioner. The air outlet frequency corresponding to the minimum energy consumption of the air conditioner is taken as the target air outlet frequency, and the air outlet speed corresponding to the minimum energy consumption of the air conditioner is taken as the target air outlet speed.
