A fan coil unit (FCU) is a type of device used in heating, ventilation, and air conditioning (HVAC) systems. It consists of a heat exchanger (either for heating or cooling) and a fan. It operates by blowing air across the heat exchanger, which either heats or cools the air before it is circulated into a room or space.
