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.
