Abstract: Appropriately increasing the flexibility of the piping can reduce the stress and strain of the piping and prevent leakage of the piping. The traditional method of improving the flexibility of piping is to increase the U-shaped pipe, but excessively increasing the U-shaped pipe not only increases the cost, but also makes the fixed frequency of piping system concentrated and increases the difficulty of keeping away the operating frequency of the compressor. Based on this, a flexible design method of air conditioning piping was studied, and the flexibility of piping was simulated and analyzed to realize the quantitative evaluation of piping flexibility. Finally, the design method was verified by stress and strain testing. The results show that the flexible design method of air conditioning piping based on CAE has higher credibility, which can make a preliminary judgment on the advantages and disadvantages of piping, and provide reference for air conditioning piping design.
