– Fan Coil Unit (FCU HVAC)
A fan coil unit (FCU) is a small terminal unit that combines a fan with a heat exchanger - to generate either heating or cooling for a space. They are also known as IDUs (Indoor Units).
A fan coil unit (FCU) may be used in a residential, commercial or industrial environment to cool or heat a space. It may be based a refrigerant-based unit (using refrigerant to generate heat or cold on a heat exchanging and blowing air over it) or it may integrate a hot or cold water loop and blow air over that.
Fan coil units can come in many shapes and sizes including Floor type, Wall type, Ceiling type, Cassette (also a type of ceiling unit) and Ducted (also known as Ceiling Concealed).
