基于分布参数法的风冷翅片管式冷凝器改进模型的研究
Study on the Improved Model of Air-cooled Fin-and-Tube Condenser Based on the Distributed Parameter Method
摘要
Abstract
This study carried out experimental and simulation investigations on the performance of the air-cooled fin-and-tube condenser(ACFTC).The experimental platform integrated key components including a compressor,a condenser,a capillary tube and an evaporating coil,with R404A adopted as the refrigerant.The operating data of the ACFTC within a specific period was recorded and analyzed.By improving the distributed parameter method,a mathematical model was established to accurately simulate the heat transfer performance of the ACFTC under both steady and transient conditions.In this model,the pipelines of the ACFTC were divided into micro-units,and a one-dimensional flow and heat transfer model incorporating air-side heat transfer,tube wall heat conduction and refrigerant flow and heat transfer was constructed.Through grid sensitivity analysis,a cell size of 4.1 mm was determined to ensure the accuracy of simulation and computational efficiency.Both experimental and simulation results show that the improved model can effectively predict the operating characteristics of the ACFTC at different outdoor temperatures.The predicted results are in good agreement with the experimental data,with errors controlled within 4 ℃ and 0.02 MPa.关键词
