Fan Coils

Fan coils are one of the most popular types of air conditioning systems used in new build and refurbished commercial premises.

CIBSE Guide B2 describes a fan coil unit as “a packaged assembly comprising heating and cooling coil(s), condensate tray collection, circulating fan and filter, all contained in a single housing”. Fan coil units recirculate air from the space continuously through the coil(s) either directly or via the void in which the fan coil is located.

A separate chiller provides chilled water and a central air handling unit provides tempered fresh air. The majority of fan coil installations use ceiling void mounted units, although a significant number of projects specify vertical chassis/recessed or cased units.
