BRIEF DESCRIPTION OF THE DRAWINGS
[0041] Figure 1 It is a flow chart of the present invention. DETAILED DESCRIPTION
[0042] like Figure 1 As shown, the power consumption evaluation method of refrigeration equipment based on the BIM simulation system includes the following steps:
[0043] Step S1: Use BIM technology to build a three-dimensional model of the building, simulate the operation of the refrigeration equipment in the three-dimensional model, set data monitoring points and obtain internal temperature data, and generate a temperature model of the building in combination with the three-dimensional model;

[0046] Step S4: adjust the power consumption of the refrigeration equipment according to the theoretical refrigeration power, monitor the actual power consumption, determine whether there are abnormal power consumption components, and perform operation and maintenance on the abnormal power consumption components.
[0047] It should be further explained that, in the specific implementation process, the three-dimensional model of the building is established using BIM technology, and the process of simulating the operation of the refrigeration equipment in the three-dimensional model includes:
[0048] Collecting architectural information of the building, which refers to the three-dimensional structure of the building, such as the size, position, shape and other information of the wall, floor, beam, column, pipe and other structures;
[0049] Collecting equipment information of refrigeration equipment, where the equipment information refers to equipment parameters of refrigeration equipment, including technical parameters and operating parameters, such as cooling capacity, energy efficiency ratio, cooling power, energy consumption efficiency, etc., as well as voltage, current, temperature, pressure, flow, etc.;
[0050] BIM technology is used to build a three-dimensional model of the building based on the collected building information, the collected equipment information is uploaded to the constructed three-dimensional model for synchronization, and the three-dimensional model containing the equipment information is imported into the energy consumption simulation software to simulate the operation of the refrigeration equipment, thereby obtaining the power consumption of the refrigeration equipment under different conditions and the changes in room temperature in the building.
[0051] It should be further explained that, in the specific implementation process, the process of setting data monitoring points and obtaining internal temperature data, and generating a temperature-visual model of a building in combination with a three-dimensional model includes:
[0052] Several data monitoring points are set at equal intervals in the three-dimensional model. Each data monitoring point has a certain monitoring area. The monitoring areas of all data monitoring points can cover the entire three-dimensional model. During the simulation, the temperature value of each data monitoring point is obtained in real time and marked as internal temperature data. The obtained internal temperature data is bound to its monitoring area.
[0053] The internal temperature data is divided into different numerical intervals according to the numerical size, and a color corresponding to the wavelength is set for each numerical interval. The larger the numerical value, the larger the wavelength. Each monitoring area is rendered in the color corresponding to its internal temperature data to realize the visualization of the three-dimensional model. The three-dimensional model that has completed the visualization is marked as the temperature vision model of the building. The temperature vision model can intuitively reflect the changes in room temperature inside the building during the running simulation process.
[0054] It should be further explained that, in the specific implementation process, the process of obtaining the refrigeration equipment point in the temperature vision model, obtaining the refrigeration distance of the data monitoring point according to the refrigeration equipment point, and obtaining the refrigeration coefficient of the data monitoring point according to the internal temperature data includes:
[0055] The refrigeration equipment point refers to each air outlet of the refrigeration equipment in the building when refrigeration is performed. Each refrigeration equipment point is displayed in the temperature vision model. The refrigeration equipment point and the data monitoring point exist independently of each other in the temperature vision model.
[0056] Taking any data monitoring point as an example, obtain the three refrigeration equipment points with the closest straight-line distance to the data monitoring point, mark the three refrigeration equipment points as the relevant refrigeration equipment points of the data monitoring point, and take the average of the straight-line distances between each relevant refrigeration equipment point and the data monitoring point as the refrigeration distance of the data monitoring point;
[0057] The temperature drop amplitude of the data monitoring point within the preset fixed time after the simulation starts is obtained. The temperature drop amplitude refers to the numerical change of the internal temperature data within the preset fixed time. The ratio of the obtained temperature drop amplitude to the preset fixed time is used as the cooling coefficient of the data monitoring point. The same method is adopted to obtain the cooling coefficient of each data monitoring point.
[0058] It should be further explained that, in a specific implementation process, a first evaluation model is constructed according to the cooling distance and the cooling coefficient, and a process of using the first evaluation model to adjust the deployment of the cooling equipment point includes:
[0059] Generate a refrigeration data set according to the refrigeration coefficient of each data monitoring point and its corresponding refrigeration distance, and divide the obtained refrigeration data set into a first training set and a first test set;
[0060] Constructing a first neural network, taking the refrigeration coefficients of different data monitoring points in the first training set as input data of the first neural network, taking the corresponding refrigeration distances in the first training set as output data of the first neural network, and training the first neural network to obtain a corresponding initial first neural network;
[0061] Using the first test set to perform model verification on the initial first neural network, outputting the initial first neural network that is less than or equal to a preset first test error threshold as the corresponding first evaluation model;
[0062] Setting a refrigeration coefficient standard, the refrigeration coefficient standard is used to reflect the expected temperature reduction range within a preset fixed time, inputting the set refrigeration coefficient standard into the first evaluation model, and obtaining a corresponding refrigeration distance standard, the refrigeration distance standard is used to reflect that only within this refrigeration distance standard can the preset refrigeration coefficient standard be achieved;
[0063] Compare the cooling distance of each data monitoring point with the cooling distance standard, and perform deployment adjustment on the relevant cooling equipment points of the data monitoring points that are greater than or equal to the cooling distance standard, wherein the deployment adjustment includes two methods: moving the relevant cooling equipment points closer and adding relevant cooling equipment points, until the cooling distances of the data monitoring points are all less than the cooling distance standard;
[0064] The same method is adopted to adjust the deployment of the relevant refrigeration equipment points of each data monitoring point until the refrigeration distance of all data monitoring points is less than the refrigeration distance standard, and the deployment adjustment information is generated according to the deployment positions of all refrigeration equipment points that meet the condition.
[0065] It should be further explained that, in the specific implementation process, the process of setting the refrigeration temperature control standard and obtaining the refrigeration power and power consumption to maintain the refrigeration temperature control standard under different external temperature data and temperature variation coefficient includes:
[0066] Setting a refrigeration temperature control standard, which is used to reflect the temperature range that needs to be maintained inside the building, and inputting different external temperature data into the temperature-viewing model, wherein the external temperature data corresponds to the internal temperature data;
[0067] According to the input external temperature data, a vertical axis is the external temperature data, and the horizontal axis is the external temperature change curve graph corresponding to the time. The external temperature data is marked at a preset fixed interval, which is recorded as W i , where i = 1, 2, ..., n, n is the number of marked external temperature data, and the temperature variation coefficient of different external temperature data is obtained, denoted as B i ;
[0068]
[0069] Get the mean of all external temperature data in the external temperature change curve and mark it as the external temperature standard W0. Compare the external temperature data with the external temperature standard. If W i >W0, the corresponding temperature coefficient is marked as +B i , if W i <W0, then the corresponding temperature coefficient is marked as -B i ;
[0070] Since the temperature-dependent model is a theoretical model, it is possible to simulate the operation of the refrigeration equipment under different external temperature data and temperature variation coefficients for the purpose of maintaining the refrigeration temperature control standard. During the operation simulation, the refrigeration power and power consumption of the refrigeration equipment are recorded in real time, and the refrigeration power and power consumption under different external temperature data and temperature variation coefficients are bound separately.
[0071] It should be further explained that, in the specific implementation process, the process of obtaining the actual external temperature data and the actual temperature variation coefficient and inputting them into the preset second evaluation model to obtain the theoretical cooling power and the theoretical power consumption includes:
[0072] According to the obtained deployment adjustment information, the refrigeration equipment points are deployed and adjusted in the actual application scenario, the actual external temperature data is monitored, and the corresponding external temperature change curve is constructed. The latest actual temperature change coefficient is obtained according to the external temperature change curve in the same way as the temperature change coefficient is obtained;
[0073] The preset process of the second evaluation model is as follows:
[0074] Generate a temperature control data set according to the cooling power and power consumption under different external temperature data and temperature variation coefficients, and divide the obtained temperature control data set into a second training set and a second test set;
[0075] Constructing a second neural network, taking the external temperature data and the temperature variation coefficient in the second training set as input data of the second neural network, taking the corresponding refrigeration power and power consumption in the second training set as output data of the second neural network, and training the second neural network to obtain a corresponding initial second neural network;
[0076] Using the second test set to perform model verification on the initial second neural network, outputting an initial second neural network that is less than or equal to a preset second test error threshold as a corresponding second evaluation model;
[0077] The latest actual temperature variation coefficient and its actual external temperature data are input into the constructed second evaluation model to obtain the corresponding theoretical cooling power and theoretical power consumption.
[0078] It should be further explained that, in the specific implementation process, the power consumption of the refrigeration equipment is adjusted according to the theoretical refrigeration power, the actual power consumption is monitored, and it is determined whether there are abnormal power consumption components. The process of operating and maintaining the abnormal power consumption components includes:
[0079] In actual application scenarios, the refrigeration equipment is continuously adjusted to the latest theoretical refrigeration power to achieve corresponding power consumption adjustment. The power consumption adjustment can keep the refrigeration equipment at the optimal refrigeration power while keeping the room temperature stable.
[0080] The actual power consumption of the refrigeration equipment after deployment adjustment and power consumption adjustment is monitored, and the actual power consumption obtained is compared with the theoretical power consumption. If the actual power consumption is less than or equal to the theoretical power consumption, no other operation is performed on it.
[0081] If the actual power consumption is greater than the theoretical power consumption, the actual local power consumption and the theoretical local power consumption of each device component of the refrigeration equipment are obtained in the actual application scenario and the temperature vision model, and compared respectively. The device components whose actual local power consumption is greater than the theoretical local power consumption are marked as abnormal power consumption components, and the abnormal power consumption components are operated and maintained, including inspection and replacement.
[0082] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
