How Do Fan Coil Units Work?
A fan in a fan coil unit (FCU) pulls air from a room into the device and distributes it over a cooling or heating coil. Either colder or hotter air is released from the FCU than before. They are frequently mentioned where there are numerous small spaces that need individual control and are used in some workplace buildings and shopping malls. FCUs are typically added to buildings where the bulk of the air conditioning is provided by other HVAC systems. A chilled water coil for chilling and either a hot water coil for heating or an electric heating element are typically found in FCUs. A chiller in the central facility provides chilled water, and a boiler produces hot water. FCU systems are efficient, and with proper upkeep and operation, they are capable of producing high levels of efficiency. They are typically less effective than common substitutes like displacement systems, chilled beams, and variable volume air cooling. The fan coil unit's operations are controlled by a ...
