A Guide to Fan Coil Unit Selection and Specification
Fan Coil Units (FCUs) are air conditioning systems popular in commercial and residential buildings. They consist of a fan, a heating and/or cooling coil, and a control system that regulates the air temperature distributed throughout the space.
The main source of noise in a fan coil is the small fan that circulates air through the coil and into the conditioned space. Figure 13.9 gives measured sound power levels at several rates of flow. When a fan coil unit is located above a T-bar ceiling the noise it generates is difficult to control even with lined ductwork or silencers. . Wherever possible fan coils should be …
