''Fan Coil Unit''
A fan coil unit (FCU) is a simple device consisting of a heating or cooling coil and fan. It is part of an HVAC system found in commercial, and industrial buildings. Typically a fan coil unit is not connected to duct work, and is used to control the temperature in the space where it is installed, or serve multiple spaces. It is controlled either by a manual on/off switch or by thermostat. The FCU is a simple appliance that works by itself, rather than as a component in an HVAC system. It contains only a coil and a fan to re-circulate indoor air in a smaller space because it does not use ducts to deliver further. The function is carried out as the fan transfers air over the coil to change the temperature warmer or cooler before pushing it out into the room.Fan coil units have been selected to provide local heating and cooling for many years and there are still many positive attributes that justify the choice of a fan coil unit system today.
