摘要
以理论模型为基础,对R134a单元式风冷冷风机组翅片管式蒸发器进行设计。应用管内流动沸腾换热模型仿真分析R134a的质量流量对沸腾换热的影响,利用外掠翅片管束换热关联式计算管外翅片侧表面换热系数,进而得出翅片管蒸发器总传热系数,利用计算结果进行设计。
air-conditioni Bases on theoretical model, makes design on Applies flow boiling heat transfer model, fin-tube evaporator of R134a unit analyzes the influence of R134a mass flux on boiling heat transfer, calculates fin-side surface heat transfer coefficient using fintube bundle heat transfer correlation, then obtains total heat transfer coefficient of fin-tube evaporator, carries out design using calculation result.
