摘　　要：为了推广平行流冷凝器在家用空调器中的应用,根据经验传热及压降关联式,采用数值模拟的方法,研究家用空调器中平行流冷凝器翅片参数对其空气侧传热流动性能的影响规律。结果表明:适当减小平行流冷凝器的翅片高度和翅片间距,可提高其换热系数、增加压降,保证其换热性能变化较小。In order to develop the application of paralled flow condenser in domestic air condition, the effect of fin parameters on the air-side heat transfer and flow characteristics of parallel flow condenser was studied by means of numerical simulation based on empirical heat transfer and pressure drop correlations. The result shows that reducing the fin＇ s height and pitche of the parallel flow condenser could raise the airside heat transfer coefficient and pressure drop and make little change of heat transfer performance when applied in domestic air-conditioner.
