摘要
针对一款美式风管机上面的V形翅片管式换热器,利用Fluent软件中的多孔介质模型,模拟了V形翅片管式换热器中空气流动的不均匀性分布情况。经过对比分析,表明该模型能够较准确的计算出V形翅片管式换热器空气侧风速的不均匀分布情况。结合翅片管式换热器设计软件EVAP-COND和Coil Designer软件,计算换热器换热及制冷剂出口状态,合理安排管路布置。
In this paper, we mainly discussed the application of the porous media and distributed resistance model in the software of Fluent in numerical simulation of V-shaped fin-tube heat exchanger. Using this model to simulate the air maldistribution, and compare it with the experimental result. Then we can evaluate the heat transfer performance using the software of EVAP-COND and Coildesigner, and optimize the circuit layout of the fin-tube heat exchanger.
