Research on Thermodynamic Design of Seawater-Mixed Refrigerant Heat Exchanger
摘要
Abstract
The field measurement data of seawater-mixed refrigerant heat exchanger showed condensation process of mixed refrigerant comprised the integral condensation from the inlet to phase separation,differential condensation and the direct contact cooling at the outlet in the shell.To investigate the separation point between integral condensation and differential condensation,a physical model of the condensation process was established in Aspen Hysys.Condensing heat transfer coefficient of mixed refrigerant was calculated using the Bell-Ghaly method.The results compared with the original design showed that the deviation of the effective heat transfer area and the effective length were both only 0.16％.The validity of the physical model and calculation method is verified,which can provide reference for the thermodynamic design of seawater mixed refrigerant heat exchanger.关键词
