J Indicates the number of energy types used during construction and installation, K Indicates the number of types of main building materials used in the construction and installation process, N Indicates the number of transportations during construction and installation.
[0024] The carbon emission accounting model in the operation phase includes: The data acquisition module is used to obtain the equipment operation data and environmental data of the air source heat pump at each time period during the operation stage.
[0025] Among them, equipment operation data and environmental data can be obtained in real time through Internet of Things technology, and each time period (unit time period) in the operation stage together constitutes the entire operation stage.
[0026] Specifically, the equipment operation data and environmental data are the data that change over time in a unit period during the operation stage. The equipment operation data in the present invention includes the power consumption data P(t) of the air source heat pump, and the environmental data includes the temperature and humidity data of the environment in which the air source heat pump is located. By considering the changes in the equipment operation status and the external environment at the same time, the carbon emissions can be estimated more accurately, thereby avoiding the deviation caused by a single variable.
[0027] The input data construction module is used to perform empirical mode decomposition on the equipment operation data, select specific modal components as equipment operation characteristic data, and construct input data for each time period in combination with environmental data.
[0028] Empirical Mode Decomposition (EMD) is a data analysis method used to process nonlinear and non-stationary signals. By decomposing equipment operation data using EMD technology, complex time series signals can be decomposed into a series of modal components (IMFs). These IMFs can better capture the intrinsic characteristics and trends in the data.
[0029] The present invention selects the modal component most relevant to carbon emissions from the decomposed multiple IMFs as characteristic data, which helps to improve the prediction accuracy of the model.
[0030] The present invention not only takes into account the equipment operation data of the air source heat pump itself, but also adds environmental data (such as temperature, humidity, etc.) to construct input data, which can more accurately reflect the energy consumption of each period under actual working conditions.
[0031] For example, empirical mode decomposition is performed on the equipment operation data to obtain n components from IMF1 to IMFn. The two IMF components IMF1 and IMF2 are selected as the equipment operation characteristic data. Combined with the environmental data H(t), the input data is constructed as [IMF1, IMF2, H(t)].
[0032] As an optional embodiment, the present invention provides a method for determining a specific modal component, comprising: (1) Calculate the correlation coefficient between each IMF component and carbon emissions and the corresponding P value.
[0033] The correlation coefficient describes the strength and direction of the relationship between two variables. The P value is used to measure the statistical significance in hypothesis testing. The smaller the P value, the more reason there is to reject the original hypothesis (usually "no relationship" or "null hypothesis"). The commonly used significance level is 0.05, that is, if the P value is less than 0.05, the result is usually considered statistically significant.
[0034] The correlation coefficient may be a Spearman rank correlation coefficient or mutual information. The Spearman rank correlation coefficient is suitable for nonlinear but monotonic relationships, and the mutual information is suitable for capturing linear and nonlinear correlations.
[0035] (2) Select significantly correlated IMF components; The significantly correlated IMF components are selected based on the P value and the correlation coefficient. For example, the IMF components with a P value less than a first preset threshold (such as 0.05) and a correlation coefficient greater than a second preset threshold (such as 0.5) are selected as specific modal components.
[0036] If the Pearson correlation coefficient between a certain IMF component and carbon emissions is 0.8 and the P value is 0.001, it means that there is a strong positive correlation between the two variables and this correlation is statistically significant. In this case, this IMF component can be used as a specific modal component.
[0037] If the mutual information between a certain IMF component and carbon emissions is 0.6 bits, but the P value is 0.1, although the dependence is strong, it is not statistically significant, and this IMF component cannot be used as a specific modal component.
[0038] Through the above method, the relationship between variables and their statistical significance are comprehensively evaluated, so as to select the significantly correlated IMF components.
[0039] The unit time period carbon emission estimation module is used to input the input data of each time period into a pre-trained carbon emission prediction model to obtain the carbon emissions of the air source heat pump in each time period; the carbon emission prediction model is trained based on the input data samples and the corresponding carbon emission label samples.
[0040] The carbon emission prediction model may be a neural network model or a support vector machine model, a random forest regression or other machine learning model. Of course, the model may also be a statistical model.
[0041] The cumulative statistics module is used to determine the carbon emissions during the operation stage according to the carbon emissions of the air source heat pump in each period during the operation stage.
[0042] The present invention can realize dynamic tracking of carbon emissions by continuously collecting and analyzing data in each time period, timely discover abnormally high energy consumption, and quickly take measures to make adjustments, which helps to reduce unnecessary energy waste.
[0043] The present invention can provide carbon emission information for each time period, help managers identify peak energy consumption periods, and adjust equipment operation strategies accordingly, such as performing maintenance or reducing loads during non-peak hours; detailed time period records facilitate retrospective review of energy consumption at specific time points or intervals, which is helpful for problem diagnosis and formulation of improvement measures.
[0044] In summary, this carbon emission accounting method in the operation phase provides strong support for more accurate and efficient carbon emission management through refined data processing, comprehensive consideration of environmental factors, intelligent prediction based on machine learning, and dynamic monitoring and feedback mechanism.
[0045] The carbon emission accounting model for the demolition stage is: ; ; ; Carbon emissions during the dismantling phase of the air source heat pump, The carbon emissions from the use of mechanical equipment during the removal of the air source heat pump. Remove carbon emissions from waste transport for air source heat pumps, The first step in the removal of the air source heat pump p Use of construction machinery and equipment q The energy consumption per shift, For the q Carbon emission factor of each energy source, For the p Energy consumption per unit shift of various construction machinery and equipment, For the m The transportation distance of the waste transported each time, Q m For the m The weight of waste transported each time; T m For the m The carbon emission factor of the transportation distance of the transportation method used for transporting the waste; P Indicates the number of types of construction machinery and equipment in the demolition phase, Q represents the number of energy types used in the demolition phase, M Indicates the number of transports during the dismantling phase.
[0046] Based on the content of the above embodiment, as an optional embodiment, the present invention provides a method for calculating carbon emissions throughout the life cycle of an air source heat pump project. Figure 2 is a flow chart of a method for determining a specific modal component provided by the present invention, such as Figure 2 As shown, the steps include but are not limited to the following steps: Step 201: Obtain carbon emission labels corresponding to equipment operation history data and environmental history data.
[0047] Historical operation data, such as power consumption history data, and environmental history data can be extracted from the air source heat pump system based on previously recorded historical data, and the corresponding actual carbon emission labels can be obtained. These labels can be calculated based on actual energy consumption records.
[0048] Step 202: Perform empirical mode decomposition on the equipment operation history data to obtain multiple modal components.
[0049] Step 203: construct different modal component combinations and combine environmental historical data and carbon emission labels as training data to train carbon emission prediction models respectively.
[0050] Different subsets are selected from all modal components to form multiple possible modal component combinations; each modal component combination is combined with relevant environmental historical data (such as outdoor historical temperature and historical humidity), and carbon emission labels are attached to form training samples. These training samples are used to train multiple carbon emission prediction models, and a variety of machine learning algorithms can be used, such as random forests, support vector machines (SVMs), or neural networks.
[0051] Step 204: Use cross validation to evaluate the carbon emission prediction model corresponding to each modal component combination.
[0052] For each trained model, apply K-fold cross validation or other appropriate validation techniques. Calculate and compare evaluation metrics of different models, such as mean square error (MSE), mean absolute error (MAE), determination coefficient R² wait.
[0053] Step 205: Combining the modal components with the best evaluation results as specific modal components.
[0054] According to the results of cross-validation, the modal component combination corresponding to the "best" carbon emission prediction model is selected as the best modal component combination. This "best" can be defined according to specific needs, such as the lowest prediction error or the highest prediction accuracy.
