【摘要】 采用一种新的冷凝换热模型,对R134a外螺纹管水冷冷凝器进行研究。通过样机设计,并在多功能焓差室标准工况下进行试验,由试验数据反推外螺纹管水冷冷凝器的管外平均冷凝换热系数。通过比较发现,冷凝换热系数的模型计算值比试验值大15%。更多还原

【Abstract】 A new type of condensation heat transfer model was used to research on water-cooling condenser of external screw tubes.Through design sample equipment and experiment in multifunctional enthalpy-difference room,then average condensation heat transfer coefficient of external screw tubes water-cooling condenser from experiment data was deduced.The comparison results show model’s calculation value of condensation heat transfer coefficient is big 15% than experiment value of condensation heat transfer coefficient.更多还原
