What is Fan Coil Unit?

A fan coil unit, or FCU, is a small HVAC unit that uses a fan and a heating or cooling coil to control the temperature of a room or space.

Definition

A fan coil unit is an HVAC device that circulates air over a heating or cooling coil to change the temperature of a space.

Purpose

A fan coil unit is used when heating or cooling needs to be controlled in a specific area of a building. The unit pulls air from the room, passes it over a coil, and sends the conditioned air back into the space. An HVAC fan coil unit can be connected to a central heating or cooling system that supplies hot or chilled water. Trane fan coil units are one example of the equipment used in these types of HVAC systems.

Examples of Use

  • Hotels: Fan coil units are often used in individual guest rooms so each room can have its own temperature control.
  • Office buildings: An HVAC fan coil unit can serve individual rooms or zones within a larger building.
  • Residential buildings: FCUs can be installed in apartments where different rooms or units need separate temperature control.

Notes

  • Fan coil units can provide heating, cooling, or both, depending on the system.
  • They are commonly installed in ceilings, walls, or other areas close to the space they serve.
  • Trane fan coil units are available in different configurations for residential and commercial applications.
