Fan Coil Units

Fan coil unit systems are all-water systems and include a finned-tube coil, filter and fan. The fan circulates air continuously throughout the space. Cooling and heating is provided by chilled water, hot water, steam or electric heating coils. A cleanable filter is located inside the unit to prevent the coil from becoming dirty with room induced debris.

Two basic types of fan-coil units exist: 2-pipe and 4-pipe. A 2-pipe system means there is one pipe for supply (either chilled or hot water) and one pipe for return serving each fan-coil unit. This means that all units in the system either receive hot or cold water simultaneously. At a predetermined set-point the entire system changs from one mode (either cooling or heating) to the other mode. This is called a 2-pipe changeover system. This means that there cannot be any simultaneous heating and cooling provided to different zones in the building. In the intermediate seasons, spring and fall, a 2-pipe changeover system will not function very well and tenant comfort will likely be jeapordized, therefore they are not recommended for commercial buildings with varying internal loads. The advantage of a 2-pipe system are the reduced installation cost savings for piping.

The other type of fan-coil system in use is a 4-pipe distribution system. This system consists of a separate supply and return pipe for chilled as well as hot water. Although higher in first-cost than a 2-pipe system, a 4-pipe system provides simultaneous heating and cooling at different zones of the building and requires no changeover control system. Another control advantage is the fact that a room temperature setpoint "dead-band" can be maintained in each zone. This prevents the fan-coil unit from switching rapidly back and forth from cooling to heating or supplying simultaneous heating and cooling from the same fan-coil unit.

Fan-coil units are available in many sizes and orientations from vertical, horizontal, loboy, ceiling-mounted and wall-hung and offer flexible control options which make them a good choice for large facilities such as office buildings, hospitals and schools.
