The widely applications have been achieved for falling film evaporators in the fields of pharmaceutical
chemical
ocean desalinization industries. However
the employment in the refrigeration and air condition was just after 1990. As so far
the researches for falling film evaporator were mainly focused on figuring out the influence of the parameters
as well as the coupling among them. Nevertheless
due to the special configuration and complexity of heat and mass transfer in the falling film evaporator
the researches were still on the preliminary level. On the basis of the illustration of the operation mechanism
this paper discussed about the influence of configuration and height of the liquid feeder
evaporation tube (including radius
the bundles
enhanced surface)
working fluid (flow pattern
flow rate) on the performance of the horizontal falling film evaporator. Consideration the great advantages of the empirical correlation in the practices
the heat transfer correlations and applied ranges were also presented. This paper can be a reference of future researches.
