Abstract and Keywords

Abstract: This paper proposes a vector search algorithm based on escape method for the complex configuration requirements and difficulty in quantifying experiential rules of air conditioning compressor piping layout problems. The algorithm consists of two processes: preprocessing and search. In the preprocessing process, a three-dimensional grid is utilized to record spatial information of the piping layout, with grid size determined by the diameter of the pipings. Different shapes of cells are used to partition the grid for piping layouts with or without configuration requirements, ensuring the required precision of cells and reducing computational complexity. In the search process, a vertical vector circular search is adopted for pipings with configuration requirements, while a vertical-horizontal vector alternating search is used for pipings without configuration requirements, to ensure that the pipe routing complies with the specifications for air conditioning piping layout. The effectiveness of the algorithm is validated through case analysis, providing algorithmic support for the development of automatic piping layout technology in air conditioners under complex constraints.

Keywords: air conditioning; piping; configuration constraints; space vector search; escape method

摘要和关键词

摘要: 针对构型要求复杂且经验类规则难以量化的空调压缩机管路布置问题, 文章提出一种基于逃逸法的向量搜索管路布置算法。该算法分为预处理和搜索 2 个过程。在预处理过程中, 使用三维网格记录管路布置空间信息, 根据管路直径确定网格大小。对于有无构型要求的 2 种管路, 采用不同形状的单元格来划分网格, 保证单元格精度满足要求, 减少算法运算量。在搜索过程中, 有构型要求管路采用竖直向量圆周搜索, 无构型要求管路采用竖直水平向量交替搜索, 确保走管路径符合空调管路布置规范要求。通过算例分析验证了该算法的有效性, 可为突破复杂约束条件下空调器管路自动布管技术提供算法支撑。
