FAN COIL

A fan coil unit is a heat exchange device consisting of heat exchanger coil and
forced air fan. Fan coil units circulate hot or cold water through circuits
embedded within the coils and moves the room air over, to heat or cool the
air in order to condition a space. Hot or cold water provided through a heat
pump would circulate in the coil, to remove or add heat to the air through
heat transfer. Speed control of the fan motor within a fan coil unit is
effectively used to control the heating and cooling output desired from the
unit.
