摘要:
通过实验研究了板壳式热交换器内制冷剂R410A的蒸发传热特性，分析了饱和温度、质量流率和平均干度对蒸发传热系数及两相摩擦压降的影响。将实验数据与现有的蒸发传热预测模型进行比较，拟合得到了板壳式热交换器内R410A蒸发传热努塞尔数和摩擦因数的关联式。研究结果表明，R410A的蒸发传热系数随平均干度的增大先增大后减小，随质量流率的增大而增大，随饱和温度的升高而减小。两相摩擦压降随平均干度、质量流率的增大而增大，随饱和温度的升高而减小。R410A努塞尔数、摩擦因数的关联式计算值与实验值的平均误差绝对值分别为3.78%、4.08%。
Abstract:
The evaporation heat transfer properties of refrigerant R410A in a plate and shell heat exchanger were investigated experimentally，and the effects of saturation temperature，mass flow rate，and average vapor qualities on the evaporation heat transfer coefficient and two-phase frictional pressure drop were analyzed. The experimental data were compared with existing correlations，and the correlations of Nussel number and friction factor of R410A in plate and shell heat exchanger is obtained by fitting. The results show that the evaporation heat transfer coefficient of R410A increases and then decreases with increasing average vapor qualities，increases with increasing mass flow rate，and decreases with increasing saturation temperature. The two-phase frictional pressure drop increases with average vapor qualities and mass flow rate and decreases with saturation temperature. The average error absolute value between the experimental values and the calculated values of the evaporation heat transfer coefficient is 3.78%，while the friction factor is 4.08%.
