Analyze the influence factors of falling film evaporation heat exchange quality on horizontal tubes in refrigeration system

This paper was concerned with the basis research of falling-film evaporators on refrigeration system.The development background,the development progress,working principle and construction of the falling-evaporators was introduced.The influence of distributor,flow character of liquid film,the arrangement and surface feature of pipes,as well as gas disturbance and lubricating oil were discussed respectively.The falling film evaporators was compared with others at last.
