摘　　要：针对多元微通道平行流冷凝器,运用分布参数法建立稳态理论模型.根据变工况实验拟合空气侧摩擦因子计算公式.分析了迎面风速、进风温度及制冷剂流量对冷凝器换热性能和压降的影响.结果表明,模型计算结果与实验数据变化趋势一致,最大误差为9.759%.证明了模型的正确性及有效性,可为多元微通道平行流换热器的结构优化及性能分析提供参考.The theoretical model of the multiple micro-channel parallel flow condenser was established based on the method of distribution parameters. The formula of air side friction was summarized based on the experiment with variable conditions. The impact of air velocity, inlet air temperature and refrigerant mass flow rate on heat exchange capacity and pressure drop of condenser were analyzed. The calculated re suhs of the model were compared with the experimenlal data, which showed a good agreement in changing trend and verified the correctness of the model. Its maximum error was 9.759%. This paper can provide reference for the structure optimization of multiple micro-channel parallel flow condensers and the perform ante analysis of heat exchangers.
