Description

Technical Field

[0001] The present invention relates to the technical field of piping selection of air-conditioning systems, and in particular to an air-conditioning piping calibration method that is not restricted by codes, and a corresponding air-conditioning piping selection method. Background Art

[0002] For large air conditioners used in buildings, it is usually necessary to first select the model and design the pipelines before determining the detailed product structure and installation location of the final air conditioning system.

[0003] Currently, air conditioning selection software is mainly divided into three categories.

[0004] One is the more traditional air conditioning matching relationship and load, working condition verification selection mode; the other is the construction design selection mode based on architectural drawings, which is divided into CAD plug-ins and third-party plug-ins to edit DWG files; the last one is to load the floor plan in PDF, picture and other formats through the program and then edit it, and finally output the piping selection report in PDF format.

[0005] Each of the three methods has its own advantages and disadvantages. The traditional mode is not difficult to develop and has a low user learning cost, but the data entry of piping and other data is troublesome and inefficient, and can only meet the customer's minimum usage needs; the CAD plug-in mode is mainly restricted by CAD copyright and has a high development cost, but the output content can be directly used for construction design; the last mode has a moderate development difficulty, and the selection output content is between the traditional mode and the plug-in mode, which can greatly improve customer selection efficiency and reduce learning costs, but the accuracy of the design drawings output by the project is slightly lower than that of the design drawings output using CAD design.

[0006] Therefore, how to provide a selection software that can meet the requirements of accuracy and has relatively low R&D costs is a problem to be solved.

[0007] In addition, during the selection process, after the piping structure of an air-conditioning system is preliminarily determined, the piping structure needs to be verified. When the piping structure can meet all verification conditions, the piping structure can be finally determined.

[0008] The code for verifying the piping structure of the existing air-conditioning system is written together with the air-conditioning selection software. Taking the verification of the indoor pipe length as an example, the indoor pipe length needs to be calculated during the verification process, and then it is determined whether the pipe length exceeds the length limit. Because in the code, the inspection rules and restrictions of different types of systems and equipment have been determined according to established requirements, but when customers need to add special verification requirements, the software will not be able to meet the customer's special inspection and verification requirements through simple operations. It is necessary to modify the underlying code of the verification module to meet customer customization requirements, which greatly increases the burden of R&D work. At the same time, when making third-party equipment compatible with customer requirements, it takes a lot of effort to carry out secondary development and compatibility, and the scalability is poor. Summary of the invention

[0009] In order to solve the technical problem in the prior art that verification of air-conditioning pipelines is restricted by codes, the present invention proposes an air-conditioning piping verification method and an air-conditioning piping selection method.

[0010] The air conditioning piping calibration method proposed by the present invention comprises:

[0011] pre-define an independent comparison module and at least one operation module;

[0012] Receive the verification rule table determined by the user according to the installation environment;

[0013] According to the identification of the pipeline structure, traverse from the main pipe of the pipeline structure;

[0014] When the parameters of the pipeline structure need to be calculated during the traversal process, the parameters to be calculated and their corresponding calculation range identifiers are input into the calculation module for calculation, and the calculation results are output;

[0015] At the same time, during the traversal process, according to the verification rule table, the parameters or calculation results of the pipeline structure to be judged are input into the comparison module, and the comparison module performs logical judgment according to the verification rule table and outputs a pass or fail result.

[0016] Further, the operation module is an addition module; or the operation module includes an addition module and a multiplication module.

[0017] Further, when the parameter to be calculated and its calculation range identifier are input into the addition module, if the addition module receives a calculation range identifier that is the same as the previous calculation range identifier, the current parameter to be calculated is accumulated on the basis of the previous calculation result;

[0018] When the addition module receives a calculation range identifier different from the previous calculation range identifier, a new round of accumulation is started based on the currently received parameters to be calculated.

[0019] Further, the calculation range identifier includes an outdoor side identifier and an indoor side identifier; and / or the calculation range identifier includes a branch pipeline identifier.

[0020] Further, when the parameter to be calculated and its calculation range identifier are input into the multiplication module, if the multiplication module receives a calculation range identifier that is the same as the previous calculation range identifier, the parameter to be calculated is multiplied by the previous calculation result;

[0021] When the addition module receives an operation range identifier different from the previous operation range identifier, a new round of multiplication operation is started based on the currently received parameters to be operated.

[0022] Furthermore, the operation range identifier is an identifier of a formula related to the coefficient.

[0023] Furthermore, the verification rule table includes parameters to be verified and verification rules corresponding to the parameters to be verified.

[0024] The air conditioning piping selection method of the present invention comprises:

[0025] Step 1, providing an interactive interface for a user to confirm a building model and a piping structure of at least one air conditioning system corresponding to the building model;

[0026] Step 2: Use the air conditioning piping calibration method described in the above technical solution to calibrate the piping structure of the air conditioning system.

[0027] Furthermore, in step 1, after the building model is confirmed, the floor plan of each floor of the building model imported by the user is received, and the scale of the floor plan and the corresponding physical building on each floor is confirmed;

[0028] Receiving the riser connection association relationship of adjacent floors determined by the user;

[0029] Calculate the load of each room in the plan view according to the scale, recommend an indoor unit combination scheme according to the load, and receive the position of the indoor unit in each room determined by the user;

[0030] Receive the floor for placing at least one external unit determined by the user, as well as the internal unit of the corresponding room to which each external unit needs to be connected, and confirm the load of the external unit;

[0031] Receiving the standpipe drilling position determined by the user;

[0032] Select available pipes according to the type of air conditioning system, recommend feasible piping structures for users to choose or adjust, and the user confirms the final piping structure.

[0033] Furthermore, before selecting available pipe fittings according to the type of the air conditioning system, the user is prompted to input a pipe fitting equipment file, wherein the pipe fitting equipment file includes basic information of the pipe fitting equipment, the location of the pipe fitting connection point, the verification rule table, and access restriction information;

[0034] Select available pipe fittings based on the pipe fitting equipment file and recommend feasible piping structures.

[0035] The present invention encapsulates the comparison module and the operation module into independent small modules, so that the verification of the pipeline structure of the air-conditioning system is not restricted by fixed codes. It only needs to input the corresponding verification file, and the main program can pass the parameters in the traversal process to the independent operation module for calculation according to the verification file, and can also pass the operation results or parameters in the traversal process to the independent comparison module for verification without modifying the code, so that the verification applicability of the present invention is more extensive and less restricted by the code. For some extremely rare cases, if the code must be modified, since the comparison module and the operation module are independent modules, the modification is also relatively convenient and the workload is relatively small.

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0046] In view of the fact that the piping structure of the existing air conditioning system is restricted by the fixed code during programming during verification, the present invention proposes a new air conditioning piping verification method.

[0047] like Figure 1 As shown, the piping calibration method of the present invention includes the following steps.

[0048] An independent comparison module and at least one operation module are predefined.

[0049] Receive the verification rule table determined by the user according to the installation environment;

[0050] According to the identification of the pipeline structure, traverse from the main pipe of the pipeline structure;

[0051] When the parameters of the pipeline structure need to be calculated during the traversal process, the parameters to be calculated and their corresponding calculation range identifiers are input into the calculation module for calculation, and the calculation results are output;

[0052] At the same time, during the traversal process, according to the verification rule table, the parameters or calculation results of the pipeline structure to be judged are input into the comparison module, and the comparison module performs logical judgment according to the verification rule table and outputs a pass or fail result.

[0053] The present invention encapsulates a comparison module for verifying rule judgment and a calculation module for calculating relevant data of a specific pipeline structure into independent modules respectively.

[0054] The comparison module is only used to perform one-by-one verification according to the verification rule table, that is, the user writes each parameter to be verified and the threshold range or limit of the parameter into the verification rule table according to the order of the verification steps. The comparison module only needs to receive the parameters to be verified sent by the main program (such as a parameter of the pipeline structure or a calculation result calculated by the calculation module) according to the order of the verification rule table, and perform one-by-one verification. This makes the code implementation of the comparison module relatively simple, and at the same time, it can also achieve the effect that the verification rules are not restricted by the code, and the verification effect desired by the user can be achieved for any air-conditioning type and any pipeline structure.

[0055] The situation is similar for the operation module. The operation module is a single operation module. For example, the operation module can be an addition module, a multiplication module, a subtraction module, or a division module. Each operation module only performs the most basic single operation, so the code implementation is relatively simple. For pipeline verification, the addition module is usually the most commonly used, such as the total pipe length on the indoor side, the total refrigerant volume, the communication line length, etc. This single operation module can be called arbitrarily by the main program, so it can also be applied to any air-conditioning system and any pipeline structure.

[0056] In one embodiment, the operation module is an addition module, that is, this embodiment only encapsulates the commonly used addition operation into a separate operation module, so as to cope with any addition operation in the air conditioning piping verification process.

[0057] In one embodiment, the operation module includes an addition module and a multiplication module. The addition operation is an indispensable operation process in the air conditioning piping verification process, so the addition module is a necessary operation module. The multiplication operation of this embodiment can be used in any place where multiplication operation is required. In the verification process, some parameters need to be multiplied by corresponding coefficients. This is a common operation process. Therefore, this embodiment also extracts this part of the operation and sets up a multiplication module separately to perform the operation, so that the user only needs to input the corresponding file, and the main program can autonomously call the multiplication module according to the file to perform the corresponding operation.

[0058] In one embodiment, when the parameter to be calculated and its calculation range identifier are input into the addition module, if the addition module receives a calculation range identifier that is the same as the previous calculation range identifier, the current parameter to be calculated is accumulated on the basis of the previous calculation result;

[0059] When the addition module receives a calculation range identifier different from the previous calculation range identifier, a new round of accumulation is started based on the currently received parameters to be calculated.

[0060] In the above embodiment, the operation range identifier is an identifier of addition accumulation. Since the addition module only performs addition operations, the addition module needs to know the starting position of the accumulation. For example, when the total pipe length of a branch of the pipeline structure needs to be calculated, the device branch ID can be used as the operation range identifier and the segmented pipe length obtained each time can be input into the addition module. When the addition module receives the device branch ID for the first time, it means that there is no previous accumulation basis for this addition operation. Therefore, the addition module receives the parameters input together with the device branch ID as the basis for this round of accumulation. When the device branch ID is received again, the parameters input twice are accumulated to obtain a calculation result. If the device branch ID is received again next time, the latest received parameters are accumulated again on the basis of the calculation result to obtain the latest calculation result. When a new operation range identifier is received, a new round of accumulation begins. The final calculation result obtained by each round of accumulation can be output in two ways. One is to obtain a calculation result each time by accumulation, and the addition module can output it to the main program, or it can be that when a new operation range identifier is received, the previous calculation result is output again.

[0061] In one embodiment, the operation range identifier includes an outdoor identifier and an indoor identifier; and / or the operation range identifier includes a branch pipeline identifier. In actual use, the addition module is mainly used to calculate the total pipe length on the outdoor side, the total refrigerant volume on the indoor side, the communication line length on the indoor side, and the total pipe length on the indoor side, etc. Since the total pipe length on the indoor side, the total refrigerant volume on the indoor side, and the communication line length on the indoor side are three related data, the addition module can calculate the three parameters in parallel, that is, the input parameter of the addition module can be more than one, and there can be multiple, and there is a certain correlation between the multiple input parameters.

[0062] In one embodiment, when the parameter to be calculated and its calculation range identifier are input into the multiplication module, if the multiplication module receives a calculation range identifier that is the same as the previous calculation range identifier, the parameter to be calculated is multiplied by the previous calculation result;

[0063] When the addition module receives an operation range identifier different from the previous operation range identifier, a new round of multiplication operation is started based on the currently received parameters to be operated.

[0064] The multiplication module, like the addition module, also requires an operation range identifier. When the previous and subsequent times have the same operation range identifier, the multiplication module performs a multiplication operation. Once the operation range identifier changes, a new round of multiplication operation begins.

[0065] In one embodiment, the operation range identifier is an identifier of a formula related to the coefficient. This allows the multiplication module to be called in the air conditioning piping verification process and even in all multiplication operations in the air conditioning piping process, which is very flexible and not limited by the code.

[0066] In one embodiment, the verification rule table includes parameters to be verified, and verification rules corresponding to the parameters to be verified. The verification rules of the pipeline structure of the air conditioner are affected by many factors, such as different types of air conditioners have different verification rules, different buildings have different verification rules for pipeline structures, and different scales of pipeline structures have different verification rules. In the prior art, if fixed codes are used to write verification rules, the verification process will be limited by fixed codes. The present invention adopts a verification rule table method. All parameters to be verified are sorted according to the verification process, and then each parameter has its corresponding verification rule. The comparison module of this application only needs to make a simple judgment based on the verification rule table. It is simple and feasible, and is not limited by the air conditioning system and pipeline structure.

[0067] The present invention can encapsulate the air conditioning piping verification separately to form a corresponding main program, and then the main program calls the comparison module and the operation module as needed to complete the verification of the pipeline structure, so that the user can verify the pipeline structure no matter how it is obtained.

[0068] Based on the above-mentioned various technical solutions, the present invention also proposes a corresponding air conditioning piping selection method. Figure 2 As shown, the air conditioning piping selection method of the present invention includes the following steps.

[0069] Step 1, providing an interactive interface for a user to confirm a building model and a piping structure of at least one air conditioning system corresponding to the building model;

[0070] Step 2: Use the air conditioning piping calibration method of the above technical solution to calibrate the piping structure of the air conditioning system.

[0071] The air conditioning piping selection method of the present invention mainly further provides some interactive interfaces for users to confirm the piping structure of the air conditioning system of the corresponding building module. Thus, from the initial construction to the subsequent piping verification, a complete set of software is provided for users to achieve their goals, which is more convenient to use.

[0072] In one embodiment, in step 1 of the air conditioning piping selection method of the present invention, after the user determines the building model through the interactive interface, the air conditioning piping selection software also needs to receive the floor plan of each floor of the building model imported by the user, and the user confirms the scale of the floor plan and the corresponding physical building on each floor, so that the actual area of ​​each room and other data can be accurately calculated.

[0073] Next, the riser connection associations of adjacent floors determined by the user are received; since the riser connection associations between adjacent floors are not known in advance, this step is to collect data statistics for all riser connection associations that may be used, that is, to convert the riser connection associations in the visualized building model into data that can be used by the code for subsequent use.

[0074] Based on the scale previously input by the user, the air conditioning piping selection software calculates the area of ​​each room in the floor plan, and the room load can be calculated based on the area of ​​the room. This process can be performed by the user specifying the corresponding room, so that the air conditioning piping selection software calculates the load according to the user's specification. After obtaining the room load, the air conditioning piping selection software recommends an indoor unit combination plan based on the load, and receives the user-determined location of the indoor unit in each room.

[0075] The air conditioning piping selection software then needs to allow the user to determine the installation floor of the outdoor unit, receive the placement floor of at least one outdoor unit determined by the user, and the indoor unit of the corresponding room to which each outdoor unit needs to be connected, and automatically calculate and confirm the load of the outdoor unit.

[0076] When both the indoor and outdoor units are determined, the user can independently select the vertical pipe drilling position, and the air conditioning piping selection software receives the vertical pipe drilling position determined by the user.

[0077] Select available pipes according to the type of air conditioning system, recommend feasible piping structures for users to choose or adjust, and the user confirms the final piping structure.

[0078] Through the above process, users can choose the appropriate air-conditioning system and corresponding piping structure according to their needs. The whole process is smooth and highly interactive, which can perfectly meet the needs of users.

[0079] In a further embodiment, before selecting available pipe fittings according to the type of air conditioning system, the air conditioning piping selection software prompts the user to enter the pipe fitting equipment file, which includes the basic information of the pipe fitting equipment, the interface display style, the location of the pipe fitting connection point, the verification rule table required for the piping verification process, and other access restriction information. The basic product information includes product series, model, basic equipment parameters, size specifications, and major system categories supported, etc. This information can accurately obtain and evaluate the comprehensive performance of a device. The interface display style is obtained by the software through the corresponding tool library based on the CAD blocks provided by the user, which is used to determine the interface display style of the device. During the conversion process, the actual size parameters of the device are obtained, and a coordinate system is constructed with the lower left corner as the origin to record the relative coordinates of the device and its defined device connection point position. The connection point refers to the location where the device is connected to other devices. When actually drawing the piping diagram, the display position of each connection point of the device is calculated by calculating the relative coordinate offset of the connection point according to the architectural drawing coordinate system and the equipment placement coordinates. Verification rules are executable low-code verification rules written by users through the modular code tools provided by the software, which are used to meet the actual computing capacity of the equipment or other computing requirements. For example, if the actual capacity of a certain indoor unit does not meet the design load requirements, the equipment that meets the requirements will be automatically screened within the same product family. Access restrictions mainly limit the use of each connection point, which are set by users through modular code tools, such as equipment usage restrictions and corresponding equipment total capacity ranges. System categories refer to the functional types of air-conditioning and refrigeration systems, such as heat pumps, heat recovery, hot water, water machines, hot water heat recovery, etc., which are used to guide the range of systems supported by the pipe fittings.

[0080] Through the importable pipe equipment files, the air conditioning piping selection software can support different types of pipe equipment. For example, it supports users to import third-party pipe equipment to participate in the selection, which greatly increases the flexibility of the air conditioning piping selection software.

[0081] Figure 3 Shown is a complete selection flow chart of the present invention.

[0082] After the air conditioning piping selection software is started, the user first creates a building model corresponding to the actual building in the interactive interface, determines the number of floors, building height, floor thickness and other data of the building, and then confirms the load calculation plan, such as confirming the calculation formula, what parameters are used, how to determine these parameters, etc. The user can provide it to the air conditioning piping selection software through the interface.

[0083] For example, air conditioning load = house area * load demand per unit area * house load correction factor. The house area can be input by the user or automatically calculated by the user circling the room area on the interactive interface. The load demand per unit area is determined by the user independently or the "house type-load" table entered by the user is then linearly interpolated to obtain the corresponding unit load, and finally multiplied by the house type correction factor.

[0084] Regarding the house load correction factor, the building materials used in different types of buildings in different countries and regions lead to inconsistent wall insulation effects. The user enters the data table in the agreed format and then queries it in the user-defined format.

[0085] The user imports the agreed type of building plan, which can be in jpg, png, pdf, svg, dwg and other formats, and completes the relationship between the riser connections between the floors. At the same time, confirm the scale of the plan.

[0086] Use the provided shortcut commands and mouse to select the room area on the building plan and enter the indoor unit selection. Enter the environmental conditions of the room, such as dry bulb temperature, wet bulb temperature, relative humidity, etc. These environmental conditions can be input by actual measurements by the user, or can be queried from the global meteorological database according to the user's region. After calculating the load demand, recommend an indoor unit combination plan that meets the load according to the user's needs. The so-called indoor unit combination plan refers to the situation where the use of a unit is not effective or cannot meet the requirements when selecting indoor units in a large area of ​​​​a house, and launch a combination of models in the same or different series. Assuming that under standard conditions, a conference room requires a cooling demand of 72kw, but a single machine that meets the cooling capacity cannot be launched, then a combination of 4 18kw machines or 7.2kw*10 indoor units can be recommended, and the user confirms the placement position to complete the indoor unit selection.

[0087] When selecting the outdoor unit, first determine the floor where the outdoor unit will be placed, determine which rooms the indoor units need to be connected to, complete the association between the indoor and outdoor units, and determine the load of the outdoor unit based on the load demand of the indoor unit.

[0088] When entering the piping process, you need to manually determine the floor drilling position, that is, determine the placement position of the riser, according to the actual design requirements. Assuming that there are two adjacent floors A and B, you need to determine two relatively vertically corresponding drilling points, and you need to determine the common structural points (columns, etc.) on the two floors. After determining the drilling position through specific structural points on floor A, record the relative offset from the structural point. On floor B, determine the structural point and use the relative offset to calculate the drilling position of building B. Select available pipe fittings and equipment based on the current system type, and recommend several feasible pipeline structures. Users can select a suitable one from the recommended pipeline structures, or further adjust the selected pipeline structure to obtain the pipeline structure to be verified.

[0089] The available pipe fittings and equipment corresponding to different system types are determined. In the embodiment of the present invention, since it supports the import of pipe fittings and equipment files, it can be confirmed according to the system types supported by the pipe fittings and equipment. At the same time, it is updated and maintained which pipe fittings and equipment are available in different types of supported systems, and users are supported to import third-party pipe fittings and equipment to participate in the selection.

[0090] The pipe equipment file mainly includes the basic information of the equipment, interface display style and pipe connection point location, as well as verification rules and access restrictions.

[0091] Taking the branch pipe as an example, the pipe equipment included in the pipe equipment file includes the branch pipe product series, the types of air conditioning systems supported, pictures of the pipe equipment, the size specifications of the branch pipe, etc. It also includes the use restrictions of the pipe equipment, the corresponding equipment total capacity range, the position of each connection point of the pipe equipment in the picture, the pipe diameter range supported by the corresponding interface, the use restrictions, the verification logic, etc.

[0092] The verification logic can be specifically reflected in the form of a verification logic table. After completing the piping selection, it is necessary to calculate the indoor and outdoor pipe lengths, verify the pipe length limit, and perform actual capacity verification on the height difference between each indoor unit and between the indoor unit and the outdoor unit. If all pass, further complete the selection of the centralized controller and the wired controller, thus completing the complete selection process.

[0093] Figure 4 The interactive identification process of the present invention is shown. After determining the system relationship, the air conditioning piping selection software of the present invention can also recognize the user's hand-drawn brief pipeline structure diagram, and through the convolutional neural network recognition combined with the current system type and the position of the internal unit, recommend several possible piping schemes for the user to select and adjust, and then perform capacity verification, automatically connect the wire controller and the centralized controller, and the user makes manual corrections again, and finally the selection data is output. The same method is applicable to the wiring process.

[0094] Figure 5 The piping optimization process of the present invention is shown. For the piping structure automatically generated by the air conditioning piping selection software, the user can also require further optimization.

[0095] The user identifies the piping that needs to be optimized, and the air conditioning piping selection software determines the current system type, obtains the accessible piping equipment, performs logical restriction verification, and then recommends possible connection structures. The user selects the structural plan and makes manual adjustments to complete the optimization.

[0096] Figure 6 An example of the piping structure automatically generated by the air conditioning piping selection software is shown in the figure. This example is a heat recovery system, where one outdoor unit controls eight indoor units. The default M1 mode converter plus a Y-type branch pipe is used, so the following is recommended: Figure 6 The pipeline structure of the M1 mode converter is not shown in this figure.

[0097] like Figure 7 As shown, after optimization, a structure that meets the logic restrictions can be completed by a Y-type branch pipe plus two M4 mode converters for users to choose.

[0098] The logical limitations of the pipeline structure include, but are not limited to: limitations on the connection length of pipe fittings, limitations on branch port utilization, limitations on branch port access capacity, etc.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
