Technical Field

The invention relates to simulation design software, in particular to a simulation design method for a pipeline capable of realizing free connection.

Background

In recent years, some industrial simulation software is more professional and more abstract, so that the use difficulty of the software is higher and higher, and particularly for the air conditioning industry, no special targeted auxiliary software exists, so that very complicated setting is needed when the general simulation software is used for designing pipelines of an air conditioning system, the learning cost of users is high, and the use is easy to make mistakes. The existing air conditioner simulation software has limited simulation modeling functions for an air conditioner system, and has many limitations, for example, when a pipeline of an air conditioner is subjected to simulation design, multi-flow-path convergence cannot be realized, and the number of liquid separation pipelines cannot be set arbitrarily according to requirements. However, in the actual pipeline design of the air conditioning system, the number of pipelines of one air conditioning heat exchanger may reach hundreds or even more, so in the prior art, for multi-path diversion, multi-path convergence, cross connection and the like of the heat exchanger modeling connection pipe, no good solution exists at present, so that part of air conditioners cannot be subjected to modeling simulation, the use freedom of simulation modeling of the existing simulation software is not high, and the use experience of a designer in modeling connection pipe is poor.

Detailed Description

The principles and embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a flow chart of a simulation design of a heat exchanger according to the present invention, which provides an interactive interface for a user to freely design a pipeline, in which the user can set the number of nodes and the number of rows of a flow path of a condenser, where the nodes refer to the number of nodes when a front pipe and a rear pipe are connected, and the number of rows refers to the number of columns of nodes. The user can also set the number of the liquid dividing pipes, an interface of pipes to be connected can be automatically generated according to the number and the row number of the nodes of the flow path and the number of the pipes of the liquid dividing pipes set by the user, the nodes of the interface when the front pipe and the rear pipe of the condenser are connected can be automatically arranged in an array, for example, the number of the nodes is 10, when the row number is 2, the nodes can be arranged in an array of 5 rows and 2 rows, and the liquid dividing pipes can be automatically arranged on the right side of the condenser. The user can perform piping operations at this interface, and can perform branch piping and/or junction piping and/or cross piping, etc. on the flow path, for example, a tee is used to join or branch multiple pipes, thereby forming a complex condenser pipe connection. The user can also set up the gas collecting pipe in the left side of condenser, then connects at least one inlet pipeline of flow path to the gas collecting pipe, connects at least two outlet pipelines of flow path to the branch liquid pipe, finally forms the pipe connection of heat exchanger.

After the pipeline connection is completed, the software judges whether the pipe connecting operation of the user meets the requirements or not according to preset connection logic, if the pipe connecting operation is wrong, the software reminds, and then obtains the pipe connecting operation of the user again. In this embodiment, the preset connection logic includes a front and rear pipe rule and a different pipe rule, the so-called front and rear pipe rule is to follow the principle that the three-way pipe is on the same plane, as shown in fig. 2, the

nodes

2, 4, and 6 are all on the same plane, that is, in front of the plane, if there is a connection error, the software prompts the user that there is an error in the pipe connection operation, and then obtains the pipe connection operation of the user again. Different pipes referred to in different pipe rules comprise a gas collecting pipe, a condensing pipe and a liquid distributing pipe, the connection of the different pipes needs to follow a one-way irreversible connecting pipe rule, follow the connecting pipe rule from the gas collecting pipe to the condensing pipe and from the condensing pipe to the liquid distributing pipe, and cannot cross the connecting pipe, namely, the connecting pipe between the gas collecting pipe and the liquid distributing pipe which does not pass through the condensing pipe is not allowed.

After the pipeline connection is judged to be correct, a user is required to set simulation parameters, the software acquires the simulation parameters set by the user and judges whether the simulation parameters meet a preset threshold value or not, if so, the simulation parameters are judged to be correct, the next step can be continued, otherwise, the user is reminded, and the simulation parameters set by the user are acquired again.

When the simulation parameters are verified, the user confirms that the simulation can be started, the software calls the API interface of the professional simulation software to perform simulation modeling on the pipeline design set up by the user, the simulation result is given, and the simulation result can be displayed to the user through the interactive interface. In this embodiment, the called professional simulation software is specifically AMESim software.

Some of the designs of the present invention are described below in connection with specific heat exchanger design examples.

Fig. 2 shows a first example of a heat exchanger design, in which the number of nodes of the flow path of the condenser is 14 and the number of rows of the flow path is 2. The heat exchanger is provided with a gas collecting pipe 200, a condenser 100 and a liquid separating pipe 300 in sequence from left to right, wherein 2 rows and 7 rows of condensers are arranged in the figure, and the modeling connecting pipe flows from left to right. The heat exchanger is connected with two pipelines from the gas collecting pipe to the node 1 and the node 3 and then to the node 4 and the node 2 respectively, so that the cross connection of two pipelines or a plurality of pipelines is realized, and the complex three-dimensional condenser pipeline is displayed in a plane interface mode. Then the node 2 and the node 4 are converged into a pipeline through a three-way pipe, and flow in from a node 6 connected with the three-way pipe, and finally are connected to a liquid separation pipe 300. The gas collecting pipe is also connected with a pipeline to the node 9, then passes through the

nodes

11 and 13, then is shunted to the nodes 10 and 12 through the three-way pipe, and can also pass through more nodes before shunting, in the embodiment, only two nodes (the nodes 11 and 13) are listed, and after passing through the nodes 10 and 12, the two nodes are converged in the same pipe through the three-way pipe, and then flows to the liquid shunt pipe 300 from the node 14 connected with the three-way pipe. From the above description, it can be concluded that the operation of the multi-pipeline cross connection, the multi-pipeline shunt connection and the confluence connection can be realized by the present invention.

Fig. 3 shows a second design example of the heat exchanger, in which the number of nodes of the flow paths of the condenser is 20 and the number of rows of the flow paths is 4. The number of the liquid distributing pipes is 5, the number of the rows of the pipes is not limited within the range of the number of the effective condenser pipes, the number of the rows of the pipes can be set randomly, the connecting pipes inside the condenser can be crossed and converged through multiple pipes, and multiple rows of the pipes can be set according to actual needs. Meanwhile, the number of the liquid separating pipes is dynamically generated according to parameters set by a designer. Therefore, the system can support the arbitrary arrangement of the number of the rows of the condenser pipes and the hot-plug dynamic modification of the number of the liquid distribution pipe flow paths.

Fig. 4 shows a third design example of the heat exchanger, in which the number of nodes of the flow paths of the condenser is 10, the number of rows of the flow paths is 2, and the number of tubes of the liquid distribution tube is 2. Of course, the invention can be used to design the condenser or evaporator separately from the heat exchanger described above.

According to the invention, after a simulation result is further obtained through simulation operation, the corresponding relation between the simulation result and each node is established, when a designer double-clicks a specific node, the corresponding simulation result can be displayed, for example, in the design example of any heat exchanger, the designer clicks the node 1, the data of the simulation result can be displayed on an interactive interface, and the designer clicks the corresponding node when needing the data of which node, so that the designer can conveniently check the simulation result and collect the air conditioner simulation data.

The implementation mode of the invention is actually an auxiliary software form for calling professional simulation software, namely a computer program or a computer executable instruction, so that the invention protects corresponding computer equipment and storage equipment, the computer equipment comprises a memory, a processor and a computer program which is stored on the memory and can run on the processor, and the simulation design method of the pipeline of the invention can be realized when the processor executes the corresponding computer program. Likewise, a storage device containing computer-executable instructions that when executed by a computer processor may implement the method of simulated design of a pipeline of the present invention.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
