A chilled water fan coil unit (FCU) works by transferring heat from the air passing over the internal heat exchanger to the chilled water passing within. Cold water is supplied by a chiller unit, or reversible heat pump, which is installed in a central plant room or on the roof of a building.

Next, the chilled water circulates through a pipework distribution system to the heat exchanger (coil) within the fan coil unit. Fans within the unit then draw air over the exchanger containing the cold water cooling the air, which is finally dispersed into the desired space to provide the occupants or building users with comfort cooling.

In the summer, this building uses chilled water and in the winter the building uses hot water which gets distributed to these fan coil units. There is an electrical heater installed for those cold off season days while the chiller is in operation.
