Fan Coil Unit

A fan coil unit (FCU) is a device used in heating, ventilation, and air conditioning (HVAC) systems to regulate air temperature and humidity levels. It is composed of a fan, a coil, and a heat exchanger. The fan blows air over the coil, which is filled with refrigerant. The heat exchanger then transfers the heat from the air to the refrigerant, cooling the air. The cooled air is then sent to the desired area. FCUs are used in both residential and commercial buildings, and can be used to provide cooling, heating, and ventilation. They are also energy efficient, as they use less energy than traditional HVAC systems. FCUs are an ideal choice for buildings that require precise temperature control, as they can be adjusted to provide the exact amount of cooling or heating needed. They are also easy to install and maintain, making them a popular choice for many building owners.
