Abstract
Considering the fact that the standby fan
also contributes in heat transfer we analyze the heat
exchanger in three different fan conditions. They are
as follows:
1. Two fans working and one standby( as
commonly used in industries),
2. All three fans remain off condition, so, only
natural convection is possible,
3. Two fans are working, which transfers heat
through forced convection and also include
natural convection through one fan off.
Then with the help of HTRI (Heat transfer
research Inc.) software we analyze performance of all
the three conditions and conclude that the number of
tube bundles can reduce for same amount of heat
transfer. This results in reduction of cost and weight of
the heat exchanger.
