The BPF depends upon the following factors:
1. The number of fins provided in a unit length i.e. the pitch of the cooling coil fins.
2. The number of rows in a coil in the direction of flow.
3. The velocity of flow of air.

The by-pass factor of a cooling coil decreases with a decrease in fin spacing and an increase in the number of rows.
Explanation:
When designing a cooling coil, the main objective is to effectively transfer heat between the air and the refrigerant. The by-pass factor is a measure of how much air bypasses the cooling coil without being cooled. It is an important factor in determining the overall performance and efficiency of the cooling system. A lower by-pass factor indicates a more efficient cooling coil.
Factors affecting the by-pass factor:
1. Fin spacing: Fin spacing refers to the distance between the fins on the cooling coil. A decrease in fin spacing means that the fins are closer together. This results in a higher surface area for heat transfer between the air and the refrigerant. As a result, more air comes into contact with the cooling coil, reducing the amount of air that bypasses the coil. Therefore, a decrease in fin spacing leads to a decrease in the by-pass factor.
2. Number of rows: The number of rows refers to the number of rows of fins in the cooling coil. An increase in the number of rows increases the surface area available for heat transfer. This allows for more air to come into contact with the cooling coil, reducing the amount of bypass air. Therefore, an increase in the number of rows leads to a decrease in the by-pass factor.
Conclusion:
In summary, the by-pass factor of a cooling coil decreases with a decrease in fin spacing and an increase in the number of rows. These design factors increase the surface area available for heat transfer and ensure that more air comes into contact with the cooling coil, reducing the amount of bypass air. This ultimately improves the efficiency and performance of the cooling system.
