Numerical model for microchannel condensers and gas coolers: Part II – Simulation studies and model comparison

摘要: For a microchannel heat exchanger (MCHX), given the working conditions, main geometric data of fin and tubes, transfer face areas, there are multiple choices for refrigerant circuitry aspect ratio. Numerical studies using Fin1Dx3 model, presented in Part I, undertaken order to assess impact on these design parameters gas cooler. The effect cuts cooler performance has also been studied numerically as function circuitry, where it found that an optimum use exists. Finally, with aim presenting model suitable tool MCHX, compared against authors’ previous (Fin2D) other representative models from literature terms accuracy computational cost. reduced simulation time by one magnitude regard Fin2D, deviates less than 0.3%.
