8.6.1 Deeper coils for higher Δ T. Sizing cooling coils for a higher leaving water temperature results in deeper row coils, since the velocity of the water is slowed, and additional heat transfer area is required. Coils in variable flow systems should be selected for a velocity of 4 ft./s (1.2 m/s), since at low load conditions, this may ...

Chilled water systems provide comfort cooling to industrial and commercial buildings all around the world. As cold water passes through the tubes of a coil, the fin surface is cooled; the entering warm air is then tempered as it passes over the fin surface of the coil. Furthermore, cooling coils can be used for dehumidification purposes.

Coils and Counter-flow: 5 Common Questions - Capital Coil Air

Jan 13, 2022 The first thing to remember about coils and counter-flow is that chilled water coils are always built to be piped in counter-flow. This means that the air flows in the opposite direction as the water. For example, with counter-flow, the air flows through rows 1-8, while the water runs through rows 8-1. Water always travels through the coil in ...
