Rows of coil selection
Rows of coil selection
(OP)
Hi Experts,
What should be parameters for a no of coils decision for a AHU.
As the coil no increases from 4 to 6 or 8, the gap becomes less and can cause a high bypass factor.
What implications should be taken care while the no of rows is decided.
Thanks in advance.
Manu

How does that connect to the sensible heat capacity that too inversely.

The number of rows you have is not the only variable in selecting a coil. You need to also consider number of fins per inch, fin material and whether or not protective coatings are needed. All these will impact a coil's capacity to one degree or another (increasing or decreasing the capacity). For example you may be able to reduce the number of rows by increasing the number of fins per inch or using a different fin material.
The best advice I can give you is to take your load calculations, air flow rate, and any special requirements (i.e. coatings or size limitations) to a manufacturer's representative and work with him/her to select a coil to match your needs.
There is to my knowledge no magical equation to determine the best coil design, number of rows, fins per inch, etc. Each coil manufacturer can vary these to provide the amount of cooling you need.
