摘要
本文探讨了汽车空调平行流蒸发器换热性能的分析方法。将平行流蒸发器沿制冷剂流动方向划分为小的计算单元,每一单元采用ε-NTU(传热效率-传热单元)算法,计算出各个单元的换热量,从而可以得出整个换热器的换热性能分布特性。计算使用的输入条件和部件实验测试条件一致,使本文的分析方法和结果具有很强的实用性。
Heat transfer distribution characteristic of MAC PFE evaporator is studied. In this analysis method PFE evaporator is divided into calculation elements according to air flow and refrigerant flow direction. The ε -NTU calculation method is employed in each element to achieve the distribution characteristic study for the evaporator.
