Finned-tube heat exchangers are the predominant type of heat
exchangers used in comfort cooling applications. They consist of a
bundle of several dozen connected tubes and the performance of
the heat exchanger as a whole is the aggregate performance of
every tube in the bundle. The heat transfer performance of each
individual tube is influenced by many parameters including the
tube and fin geometries; the refrigerant temperature, mass flux and
local quality; and the local air velocity, temperature and humidity
