Embodiment 1
[0063] In the prior art, when designing an air conditioner, the air conditioner pipeline design is carried out first, and then the air conditioner prototype is manufactured according to the design, and then the air conditioner prototype is used for actual use testing, and the faults and problems that occur during the test are recorded. Faults and problems Modify the air-conditioning pipeline design and repeat the above steps until the requirements are met.
[0064] In the prior art, the analysis process of air-conditioning pipeline design takes a long time, and consumes many air-conditioning prototypes, and the cost is high. In view of the above problems, the inventor of the present application proposes an analysis method for air-conditioning pipeline design, such as figure 1 Shown, the method that this application proposes comprises:
[0065] The modeling step is to establish an air-conditioning pipeline model according to the design of the air-conditioning pipeline;
[0066...
Embodiment 2
[0100] Such as figure 2 As shown, the application also proposes an analysis device for air-conditioning pipeline design, including:
[0101] A modeling unit 10, configured to establish an air-conditioning pipeline model according to the design of the air-conditioning pipeline;
[0102] The fluid analysis unit 20 is used to perform fluid analysis on the air-conditioning pipeline model to determine the pipeline pressure when there is refrigerant in the air-conditioning pipeline;
[0103] The static analysis unit 30 is used to perform static analysis with the pipeline pressure as the load, simulating the vibration and stress-strain distribution of the air-conditioning pipeline under the action of the refrigerant fluid;
[0104] The modal analysis unit 40 is used to perform modal analysis on the air-conditioning pipeline model by using the vibration and stress-strain distribution obtained from the static analysis as the prestress, so as to obtain the modal of the pipeline during...
Embodiment 3
[0133] In order to better illustrate the beneficial effect of the present application, another embodiment of the analysis method for the design of the pipeline on the air conditioner is proposed below.
[0134] Please see image 3 , first simulate the 3D model corresponding to the air-conditioning pipeline design. If the simulation result is qualified, then the sample is tested for prototype testing, which can greatly shorten the product development cycle. At the same time, if the simulation is unqualified, the model can be optimized according to the simulation result. Improve development efficiency. The specific operation method is as follows: 1. Design and model the pipeline of the air conditioner external unit;
[0135] 2. Obtain the original CAE model of the compressor and its piping system;
[0136] 3. Import the original model into the model pre-processing software, save the part name in the model BOM table, and use the part name to filter compressors, four-way valves,...
