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.
