R1234ze（E）在水平圆管内流动沸腾换热过程中摩擦压降特性实验研究
Investigation of Frictional Pressure Drop During Flow Boiling of R1234ze(E) in Horizontal Tube
摘要
Abstract
Recently, more attention have been paid to the new refrigerant R1234ze(E), which is supposed to be the most promising al-ternative of R134a in heat pump system. In this paper, the saturated flow boiling frictional pressure drops characteristics of R1234ze(E) and R134a inside an 8 mm ID horizontal tube were investigated. The experiment were carried out at the saturation temperature of 10 ℃with heat flux ranging from 5. 0 kW/m2 to 10. 0 kW/m2 and mass flux ranging from 300 kg/(m2•s) to 500 kg/(m2•s). The influence of mass flux and heat flux on the frictional pressure drops were examined and discussed. The results show that, the frictional pressure drops of R1234ze(E) are slightly greater than those of R134a. Meanwhile, the experimental data of the frictional pressure drops are com-pared with four well-known empirical correlations.关键词
