摘　　要：本文通过数值模拟,研究了湿工况下具有相同表面积的三种家用空调常用翅片的表面传热传质特性。分析了不同空气入口速度和相对湿度条件下,三种翅片的换热量、压降、效率指数,获得了翅片表面液滴凝结分布情况。研究结果显示,在相同表面积条件下,百叶窗翅片在效率指数方面表现出更为优越的性能。实验值与模拟值的误差在10%以内,验证了模型具有较高的准确性。The surface heat and mass transfer characteristics of three commonly-used fins were studied through numerical simulation in household air conditioners with the same surface area under wet conditions.The heat transfer rate,pressure drop,and efficiency index of the three fins under different air inlet velocities and relative humidity conditions were analyzed,and the distribution of liquid droplet condensation on the fin surface was obtained.The research results show that under the same surface area conditions,the louver fin exhibits superior performance in terms of the efficiency index.The error between the experimental values and the simulation values is within 10%,verifying the high accuracy of the model.
