FAN COIL UNITS

A fan coil unit is a relatively small piece of equipment that consists of a fan, a coil, and other components, that are used to cool or heat the air recirculating within a room. Some will also add fresh air to the space.

The units are quite common and can be found in most commercial or residential applications.

Typically, to operate in cooling mode, the fan will blow air across the chilled water coil that is fed from the building central system, with the cooled conditioned air flowing back into the room, cooling the space.

Typically, to operate in heating mode, the fan will blow air across the heating coil that is fed from the building central system, with the heated conditioned air flowing back into the room, heating the space.

The heating coil could also be an electric type.

When equipped with an independent cold or heat source, this fan with a  coil provides efficient heating/cooling, making it ideal for factories, office buildings, and other spaces. With significantly lower power consumption than central air conditioning, it delivers exceptional energy savings and reduces operational costs.

Components and Operation Components:

Heating/Cooling Coil: Core element for temperature regulation. Fan: Circulates air over the coil.

Operation:

Fan coils work by drawing in ambient air, passing it over the coil (either heated or cooled by the larger HVAC system), and redistributing the conditioned air back

into the room. They can be standalone systems or connected to a central plant.
