Experimental study on condensation of R22 saturated steam outside a horizontal C-S tube
【摘要】 以R22为工质在套管式冷凝器中对C-S水平管在饱和蒸汽状态下冷凝传热的性能进行实验研究,得出凝结换热系数与表面张力及蒸汽流速之间的关系,并拟合出其实验关系式。
【Abstract】 Experimental study on heat transfer performance of a C-S tube has been reported for condensation of R22. The result shows the heat transfer coefficient of condensation of the C-S tube is related with the surface tension and the vapor velocity, and then fits experimental relational expression.
