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.
