Chilled water coils are most often used in commercial
buildings. Chilled water coils respond to the cooling effect of
surfaces when wet by moisture condensed from the air. The sum of
sensible heat transferred by a dehumidifying cooling coil represents
total heat values. Sensible heat transfer, whether cooling or
heating, refers to the change in dry bulb temperature only. The
system characteristics that affect a chilled water coil's
performance are gallons per minute, velocities, and temperature
ranges of the fluid through the tubes as well as the cubic feet per
minute, velocities, and temperatures of air across the coil fins.
