Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of air conditioning energy consumption, and particularly relates to a central air conditioning terminal energy consumption processing method, device and storage medium based on a large language model. BACKGROUND
[0002] Central air conditioning systems have been widely used because they can provide comfortable cooling and heating environments for large spaces. A central air conditioning system usually consists of outdoor units, indoor units, and complex pipelines and control systems. Among them, the indoor unit is the key part of the heat exchange with the indoor environment, and its energy consumption plays an important role in the energy management of the entire central air conditioning system. The energy consumption accounting of the indoor unit is of great significance to improve energy efficiency and achieve energy saving and emission reduction.
[0003] The traditional central air conditioning indoor unit energy consumption calculation method has many limitations. On the one hand, the method of relying on manual recording of energy consumption data is not only inefficient, but also prone to human error. The recording personnel may be negligent, the recording time interval is unreasonable, and other factors may result in incomplete or inaccurate data. On the other hand, simple automation calculation is usually based on a relatively rough model, only considering a few fixed parameters such as running time and set temperature, without fully considering the actual operating conditions of the indoor unit. For example, the fan speed of the indoor unit, the actual heat exchange efficiency, and the influence of environmental temperature and humidity changes in different seasons and time periods on energy consumption are not fully considered in the calculation. This makes the indoor unit energy consumption calculated by the traditional method deviate from the actual energy consumption, which is difficult to accurately reflect the real energy consumption, and thus is not conducive to formulating accurate and effective energy-saving strategies and energy management measures.
[0004] At the same time, central air conditioning systems inevitably encounter various faults during long-term operation. When a fault occurs, maintenance personnel usually need to go to the scene for investigation and diagnosis. The traditional fault diagnosis method mainly relies on the experience of maintenance personnel. Maintenance personnel rely on their memory and understanding of common fault phenomena to gradually check the possible problem components and system links. However, this experience-based diagnosis method has obvious shortcomings. First, the accumulation of experience requires a long time, and it is difficult for new employees or relatively inexperienced maintenance personnel to accurately determine the fault. Second, even experienced maintenance personnel may misdiagnose or take too long to diagnose when faced with complex, rare, or multiple fault superimposed situations. For example, some faults may exhibit similar symptoms, but the actual fault root is completely different, and it is difficult to quickly and accurately determine the true fault point simply relying on experience, which not only leads to low maintenance efficiency, but also causes additional energy waste due to maintenance delays, increasing user costs and inconvenience.

[0056] Example 1
[0057] Referring to Figure 1 and Figure 2 In this embodiment, the large prediction model is combined with the central air conditioning energy consumption calculation and maintenance to more accurately calculate the energy consumption and fault diagnosis of the central air conditioning terminal, and a central air conditioning terminal energy consumption processing method based on a large language model is provided, which includes the following steps:
[0058] S1: Store the air conditioning principle materials, air conditioning fault materials, heat transfer documents, refrigeration documents, fluid mechanics documents, air conditioning materials including heating, ventilation and air conditioning, and air conditioning related data over the years into the data lake, and normalize the numerical data of the air conditioning related data over the years to obtain a data set. Specifically, in this embodiment, the related data of the air conditioner in the past 10 years is stored in the data lake. The data lake is a storage system used to centrally store data information, and can accommodate any structured and unstructured data.
[0059] More preferably, the collected document materials in multiple formats including PDF, Word, HTML, etc. are uniformly converted into formats suitable for processing and storage, such as plain text format or structured database format (such as extracting table data into a relational database table).
[0060] The air conditioning related data over the years is cleaned to remove duplicate data records, incorrect data values (such as temperature or pressure values that are obviously outside the reasonable range), and incomplete data rows or columns. For missing data, data filling techniques (such as mean filling, model-based filling, etc.) can be used for processing.
[0061] Since the air conditioning related data over the years has the characteristics of relatively uniform data distribution and known data range, the minimum-maximum normalization formula is used for conversion, as shown below:
[0062]
[0063] wherein, is the normalized value, is the original data value, and are the minimum and maximum values of the variable, respectively. This method can map the data to the [0, 1] interval.
[0064] S2: Input the air conditioning materials into the large language model for learning, select the gradient boosting tree GBM as the regression model, input the training set of the data set into the regression model for training to obtain the training model, and input the prediction set of the data set into the training model to obtain the coil control coefficient. Specifically, in this embodiment, 80% of the data in the data set is used as the training set, and 20% of the data is used as the prediction set to supervise the fine-tuning of the large language model LLM. The large language model is a pre-trained language model used to pre-train large-scale data and can simulate human learning and thinking.
[0065] The Gradient Boosting Model (GBM) effectively captures this complex nonlinearity. During training, it continuously adjusts the weights of each decision tree, allowing the model's output to more accurately approximate the actual coil control coefficient. Compared to simpler models like linear regression, it offers significant accuracy advantages in handling such complex relationships. In actual air conditioning data collection, some noise is inevitable, such as individual abnormal temperature and flow values caused by sensor measurement errors. The GBM model has a certain tolerance for this type of noise. During training, it avoids severe overfitting due to small amounts of abnormal data and can still stably learn the key patterns in the data. This ensures the reliability of the resulting trained model in predicting coil control coefficients and reduces prediction bias caused by data quality issues.
[0066] Preferably, numerical variables such as indoor and outdoor temperature, humidity, supply and return air temperature of the air conditioning system, refrigerant temperature and pressure at the coil inlet and outlet, fan speed, as well as non-numerical variables that may affect the control (such as whether the air conditioner is operating in cooling or heating mode, etc.) are input into the large language model.
[0067] The large language model analyzes the potential correlation between each variable in the data and the coil control coefficient. Using data analysis methods (such as calculating correlation coefficients between variables and assessing feature importance), it removes variables with low correlation, redundancy, or insignificant impact on the coil control coefficient, thereby selecting feature variables with a significant impact on the coil control coefficient. For example, by calculating correlation coefficients between variables (such as the Pearson correlation coefficient), variables with high correlation to the control coefficient, such as the coil inlet and outlet temperature difference, the indoor and outdoor temperature difference, and fan air volume, are identified as key features.
[0068] Import key features into the corresponding machine learning library and select the Gradient Boosted Tree (GBM)-related classes or functions to initialize the regression model. Initially set the key parameters of the Gradient Boosted Tree (GBM) based on the data characteristics and problem requirements. For example, start by setting the number of decision trees (n_estimators parameter) to a moderate value (such as 100), the maximum tree depth (max_depth parameter) to a certain number of layers (such as 5), and the learning rate (learning_rate parameter) to a low value (such as 0.1). These parameters will be further adjusted and optimized during training based on model performance.
[0069] The training set data is input into the initialized GBM regression model and iterative training begins. In each iteration, GBM constructs a new decision tree based on the residual between the current prediction result and the true control coefficient target value to continuously optimize the model's prediction ability, thereby reducing this residual and obtaining a trained GBM regression model.
[0070] The pretreated prediction set data is input into the trained GBM regression model, and the model predicts the corresponding coil control coefficient of each data in the prediction set according to the relationship between the learned features and the coil control coefficient, and outputs the corresponding prediction result.
[0071] S3: Calculate the central air conditioning energy consumption based on the coil control coefficient and real-time data, and generate an energy consumption statistical report. Specifically, in this embodiment, the coil control coefficient is a billing coefficient value calculated by the large language model, and the real-time data related to the air conditioner is collected by the collection system. The default initial coil control coefficient is 1.
[0072] Preferably, the real-time data includes:
[0073] Obtain the physical space positions and association relationships of the central air conditioner outdoor unit, coil, total electric meter, and sub-meter electric meter;
[0074] Obtain the brand, brand rated power, room area, and current electricity price of the room air conditioner;
[0075] Collect air conditioner related data related to the air conditioner on the air conditioner sensor, including air conditioner mode, wind speed, set temperature, air sweeping mode, indoor temperature, outdoor temperature, air conditioner running time, and associated sub-meter reading, and clean the air conditioner related data to ensure data validity. Specifically, in this embodiment, the collected real-time data is cleaned, denoised, and standardized.
[0076] Preferably, in step S3, calculating the central air conditioning energy consumption based on the coil control coefficient and real-time data further includes:
[0077] S31: Obtain the number of coil floors and the number of sub-meter floors based on the association relationship, and calculate the coil electricity allocation proportion based on the number of coil floors and the number of sub-meter floors.

[0078]
[0079] wherein, is the number of coil floors, is the number of sub-meter floors. Specifically, in this embodiment, please refer to Figure 3 As shown in the figure, assuming that a building has 10 floors, 9 floors are installed with sub-meters, and 8 floors are installed with coils, then , , so that the floors without coils and sub-meters can be excluded;
