Description
Technical Field
[0001] The present invention relates to the field of air conditioning, and in particular to an air conditioning energy-saving control method and system based on a digital twin model. Background Art
[0002] As global warming continues, energy issues are becoming increasingly serious, and energy conservation and environmental protection have become an indispensable part of our daily lives. As one of the main devices for electricity consumption in fixed places such as homes and offices, how to save electricity and reduce energy consumption during use is an issue that people need to pay attention to. For example, when a refrigeration air conditioner is in operation, after reaching the preset refrigeration temperature, the outdoor unit of the air conditioner (i.e., compressor, fan) will instruct the outdoor unit to stop operating through the thermostat sensing signal obtained by the air conditioner computer motherboard. Of course, when the indoor temperature exceeds the preset temperature, the outdoor unit of the air conditioner will also instruct the outdoor compressor to operate through the thermostat sensing signal obtained by the air conditioner computer motherboard.
[0003] Therefore, when starting to turn on the refrigeration air conditioner, people habitually preset the temperature to the lowest, which actually prolongs the working time of the air conditioner compressor. The longer the air conditioner compressor works, the more electricity it consumes. Therefore, experienced regulators choose to preset a higher temperature when turning on the machine, such as 28°C. When the indoor temperature reaches 28°C and the air conditioner runs a working cycle, people slowly reduce the temperature according to their needs. It can be seen from this that even if the same desired refrigeration temperature needs to be reached, using the same refrigeration air conditioner in the same set closed space, different set temperatures are initially set, and the power consumed and duration of the same refrigeration air conditioner during the refrigeration process to reach the desired refrigeration temperature are different.
[0004] For example, the Chinese invention patent publication CN107990487A proposes an air conditioner and a prediction method and device for air conditioner power consumption, wherein the prediction method for air conditioner power consumption includes the following steps: using the least squares support vector machine LSSVM algorithm to establish a prediction model for air conditioner power consumption; obtaining the current outdoor dry-bulb and wet-bulb temperature, the current indoor dry-bulb and wet-bulb temperature, and the current indoor ambient temperature; predicting the power consumption of the air conditioner according to the prediction model for air conditioner power consumption, the current outdoor dry-bulb and wet-bulb temperature, the current indoor dry-bulb and wet-bulb temperature, and the current indoor ambient temperature to obtain the power consumption value of the air conditioner. The prediction method establishes a prediction model for air conditioner power consumption through the LSSVM algorithm, eliminating complex intermediate variables and without assumptions. The prediction model established is simple and has good applicability and extensibility.
[0005] For example, the Chinese invention patent publication CN109959122A proposes an air conditioning energy consumption prediction method based on a long short-term memory recurrent neural network, comprising the following steps: Step 1, collecting data, collecting water-cooled central air conditioning data and corresponding environmental data of the normal operation of the water-cooled central air conditioning project; Step 2, preprocessing the water-cooled central air conditioning data and corresponding environmental data obtained for normal operation; Step 3, training the data set to achieve air conditioning energy consumption prediction, using the LSTM-RNN long short-term memory recurrent neural network, using the preprocessed data set and the corresponding power consumption as the input of the LSTM-RNN long short-term memory recurrent neural network, and obtaining the final prediction model after network training; Step 4, inputting the test data into the prediction model to obtain the energy consumption value of the air conditioner under the current working condition. The present invention simplifies the model training process and improves the prediction accuracy.
[0006] However, the above-mentioned prior art is only limited to the prediction of power consumption in a single working scenario of the air-conditioning equipment, for example, the prediction of power consumption under a single set temperature, and it is impossible to exhaustively predict the power consumption of each working scenario corresponding to all set temperatures as much as possible, not to mention the automatic setting of the priority set temperature based on the prediction results. At the same time, the basic data used to execute the prediction mechanism based on the digital twin model is not comprehensive and sufficient, resulting in the predicted power consumption data being not stable and reliable enough. In addition, the above-mentioned prior art is only limited to the prediction of power consumption and cannot predict other functional parameters of the air-conditioning equipment. Therefore, there is a need for a prediction mechanism based on a digital twin model that traverses the multifunctional parameters of each working scenario corresponding to all set temperatures, so as to provide more effective basic data for the energy-saving control and functional control of the air-conditioning equipment.

[0040] like Figure 1 As shown, a technical flow chart of the air conditioning energy-saving control method and system based on the digital twin model shown in the present invention is given.
[0041] like Figure 1 As shown, the specific technical process of the present invention is as follows:
[0042] Technical process 1: Design a customized digital twin model for the target refrigeration air conditioner to provide a solution mechanism for intelligent prediction of the power consumption and consumption time required by the target refrigeration air conditioner when each current set refrigeration temperature reaches the user's expected refrigeration temperature;
[0043] Specifically, the structural customization of the digital twin model lies in the following aspects:
[0044] In the first aspect, the digital twin model is a deep neural network after multiple trainings. For example, the deep neural network includes multiple hidden layers, a single input layer and a single output layer, and the multiple hidden layers are arranged between the single input layer and the single output layer.
[0045] Second aspect: the number of training times of the deep neural network is positively correlated with the compression ratio of the compressor of the target refrigeration air conditioner, so as to design digital twin models with different structures for different refrigeration air conditioners;
[0046] Third aspect: In each training of the deep neural network, the predicted power consumption and predicted consumption time corresponding to a known past set temperature are used as the two output contents of the deep neural network, and the user's expected cooling temperature, the past set temperature, the operating voltage and operating frequency of the target cooling air conditioner, various equipment data of the target cooling air conditioner, multiple internal environmental parameters of the set enclosed space corresponding to the past set temperature, and multiple external environmental parameters of the set enclosed space corresponding to the past set temperature are used as the input content of the deep neural network item by item to complete this training, thereby ensuring the training effect of each training of the deep neural network and ensuring the stability and effectiveness of the intelligent prediction results of the digital twin model;
[0047] Technical process 2: Targeted screening of multiple basic information for the digital twin model. The comprehensive and targeted screening of the multiple basic information further ensures the stability and effectiveness of the intelligent prediction results of the digital twin model.
[0048] Specifically, the above-mentioned multiple basic information includes the operating voltage and operating frequency of the target refrigeration air conditioner, various equipment data of the target refrigeration air conditioner, multiple internal environment parameters of the set closed space, and multiple external environments of the set closed space;
[0049] More specifically, the various equipment data of the target refrigeration and air conditioning are the energy efficiency ratio, applicable area, air conditioning number, cooling power, heating power, circulating air volume and frequency conversion mark of the target refrigeration and air conditioning; the multiple internal environmental parameters of the set closed space are the temperature, humidity, air pressure and space volume inside the set closed space; the multiple external environmental parameters of the set closed space are the temperature, humidity, wind direction, wind speed and sunlight angle outside the set closed space, wherein the set closed space is the space where the target refrigeration and air conditioning performs temperature control;

[0053] Specifically, when two sets of minimum predicted power consumption with equal values appear, the set refrigeration temperature with the shortest predicted consumption time corresponding to the two sets of set refrigeration temperatures with equal values is used as the priority energy-saving set temperature, thereby taking into account both air conditioning energy saving and air conditioning refrigeration efficiency, and improving the intelligent level of refrigeration and air conditioning;
[0054] It is particularly critical that the temperature adjustment range of the target refrigeration air conditioner is evenly divided to obtain a plurality of reference set temperatures, and the number of the plurality of reference set temperatures exceeds a set number threshold. Through the above settings, each selectable set temperature value of the temperature adjustment range of the target refrigeration air conditioner can be exhausted as much as possible and traversed intelligent prediction can be performed, thereby providing data guarantee for the accuracy of the priority energy-saving set temperature selection;
