What is a Fan Coil Unit?

Definition and function

A fan coil unit (FCU) is an integral part of a heating, ventilation, and air conditioning (HVAC) system. It is responsible for cooling or heating the air in a specific space, such as a room or office. The FCU consists of a heating or cooling coil, a fan, and a filter. It is usually mounted in or near the ceiling of a room and operates quietly to provide comfortable temperature control.

Components of a fan coil unit

A fan coil unit is composed of several key components that work together to ensure its proper functioning. These components include:

  1. Heating or cooling coil: The coil is responsible for transferring thermal energy to or from the air, depending on the HVAC system’s mode of operation.
  2. Fan: The fan is used to circulate and distribute the conditioned air throughout the room or space.
  3. Filter: The filter is an essential part of the FCU as it helps to improve indoor air quality by removing dust, pollen, and other airborne particles.

The Importance of Heat Exchanger Cleaning
