What is FCU for electrical?

FCU, or Fan Coil Unit, is a type of equipment used in heating, ventilation, and air conditioning (HVAC) systems. It consists of a heat exchanger and a fan, allowing it to provide heating or cooling to a space by circulating air over the coils. FCUs can operate independently or as part of a larger system and are commonly used in commercial buildings, hotels, and residential applications for localized climate control.
