[0025] Referring to Figure 1 and Figure 2 In one embodiment, a cold and heat load calculation method specifically comprises the following steps:

[0026] Step S101: exporting a standard Excel template from a cold and heat load calculation application, the standard Excel template comprising a structural relationship of a building block-floor-room.

[0027] Step S102: sending the standard Excel template to each client, so that users of each client input room parameters in the standard Excel template to obtain a first edited file, the room parameters being room parameters of a building model to be calculated for cold and heat load.

Moreover, the current device distributes the exported standard Excel template to each client, so that the users of each client edit the received standard Excel template by inputting room parameters, to realize a working mode of multi-person cooperation, wherein the way of distributing the exported standard Excel template to each client by the current device can be that the current device sends the standard Excel template to each client as a separate file, so that each client separately edits the received complete template offline, and then the current device collects the first edited files edited by each client and integrates them. Alternatively, the current device can be used as a server to map the standard Excel template to each client, so that each client simultaneously edits the mapped standard Excel template online, and then the current device directly obtains the edited first edited file. The first edited file is imported into the cold and heat load calculation application, the content of the first edited file is directly displayed in the cold and heat load calculation application in the form of a structural tree to show the building-floor-room relationship, and the room parameters are displayed in the corresponding editing column, so that the cold and heat load calculation application can calculate according to the imported room parameters. The cold and heat load calculation application is built-in with the (GB 50736-2012) Appendix H building envelope thermal database, radiator product database, room template library, and meteorological parameter database, and supports users to adjust according to actual conditions, to provide convenience and data support in the calculation process. Then, the calculation results of each room are checked through the calculation result page in the cold and heat load calculation application, the statistical results are checked through the statistical data page, for example, pie chart and column chart, and the required calculation book is exported through the output calculation book page, so that equipment selection can be performed according to the calculation results. Therefore, the scheme provided by the embodiment of the present application avoids manual setting of parameters in the software of only one device, and significantly improves the efficiency and flexibility of cold and heat load calculation compared with the prior art.

[0031] Specifically, in an embodiment, the cold and heat load calculation method provided by the embodiment of the present application further includes the following steps:

[0032] Step one: extracting room parameters from a Revit application through a preset Revit plug-in, the Revit application being used to establish a building model to be calculated for cold and heat load.

[0035] Specifically, the embodiment of the present application further provides a Revit plug-in matched with the cold and heat load calculation application, through which the room parameters can be directly extracted from the Revit application for establishing the building model to be calculated for the cold and heat load, and the extracted room parameters can be directly imported into the standard Excel template to obtain a second edited file, and the cold and heat load calculation application can perform the cold and heat load calculation by using the input second edited file, so that compared with the scheme of manual editing in the software and manual editing in the template, the flexibility and the calculation efficiency of the cold and heat load calculation can be further improved.

[0036] In the embodiment of the present application, the room parameters include engineering data, indoor design parameters, envelope parameters and heat transfer coefficient K value.

[0037] Specifically, in an embodiment, the cold and heat load calculation method provided by the embodiment of the present application further includes the following steps:

[0038] Step four: importing the result of the cold and heat load calculation into the building model in the Revit application through the preset Revit plug-in.

[0040] Specifically, in an embodiment, when a user needs to modify the room parameters in the cold and heat load calculation application, a batch modification Excel template is exported through the cold and heat load calculation application, so that the user edits the batch modification Excel template; and the edited batch modification Excel template is input into the cold and heat load calculation application to batch modify the room parameters in the cold and heat load calculation application.

[0041] Specifically, the embodiment of the present application also provides a batch modification mode, supports batch modification of room data such as envelope and indoor design parameters, and provides an export Excel template batch modification interface, which is more convenient and user-friendly for input of a large amount of complex data.

[0044] Step six: calculating the positive area of the triangle covering the current component and the negative area of the triangle not covering the current component based on the boundary vectors of the connected triangles.

[0045] Step seven: determining the current component area by using the sum of the positive area of the triangle and the negative area of the triangle.

[0046] Specifically, in the embodiment of the present application, for the component area that cannot be directly read in the Revit software, the corresponding parameter information is identified and calculated based on a polygon algorithm, realizing the function of accurate and rapid extraction of model information, and the calculation process is as follows: connecting an arbitrary plane point and each vertex in the order of the vertices of the polygon, the inner product of the connected vectors is the area of each triangle, and the component area is determined based on the area of each triangle. Figure 3For example, the inner product of vector OA and vector OB is calculated to obtain the area of triangle OAB, and the positive value is the positive area, denoted as S OAB (clockwise), and the negative value is the negative area, denoted as S OBA (counterclockwise). Therefore, to calculate the area of component ABCDE, only the positive area covered by ABCDE and the negative area not covered by ABCDE need to be summed, as shown in the following formula:

[0047] S ABCDE = S OAB + S OBC + S OCD + S ODE + S OEA

[0048] Meanwhile, for a curved surface and a curved line, the present embodiment converts the curved line into continuous small line segments for calculation by means of calculus, thereby realizing extraction of the area of any component in the Revit application.
