Feature of Fantastic Water Fan Coil


Fantastic is not only one of the largest manufacturers of heat pumps, but also professional water fan coil factory. As one of professional fan coil unit factories, Fantastic product series include ultra-thin FCU, wall-mounted FCU, ceiling FCU, floor-standing FCU, cassette FCU and so on. Compare with other water Fan Coil factories, Fantastic can provide heat pump and water fan coil to the client at the same time. We hope this post helps you understand what is water fan coils before you look for a Fan Coil unit factory.

A water fan coil unit (FCU) contains a fan that draws the air in space into the unit then blows it over a cooling or heating coil. The air comes out of the water fan coil either cooler or hotter than before. They are used in some office buildings and shopping centers and typically specified where there are multiple small spaces requiring individual control. Typically an individual water fan coil serves only up to 150m², so there can be tens or even hundreds in a building. Water fan coils are, however, most commonly used as a supplement to a building for which other HVAC systems provide the majority of the air-conditioning.

Water fan coil units will generally have a chilled water coil for cooling and either a hot water coil for heating or an electric heating element. Chilled water is provided from a chiller located in the central plant, and hot water forms a boiler.

Each FCU is provided with a small supply of outside air to ensure adequate ventilation.

Energy efficiency

FCU systems are of average efficiency only but if well maintained and operated can produce a good level of efficiency.  They are generally not as efficient as standard alternatives such as variable volume air conditioning, chilled beams and displacement systems.

Running costs

The age and condition of FCU systems will significantly affect running costs.  Older systems tend to have higher rates of a temperature controller failure, poorly operating valves and inefficient central plant, all of which can increase costs.

As with all systems, efficiency will be improved by good management and commissioning, especially in relation to the calibration of temperature sensors and the maintenance of valves.  A building management system (BMS) will provide a higher level of control and if well managed will help reduce running costs.

Retrofit/improvement opportunities

The major areas for improvement for FCU systems are:

Review and optimization of zone temperature control for FCUs.
Recommissioning and maintenance of chilled water and hot water flow balancing and valve operation.
Upgrade of controls for boilers, chillers and associated pumps
Upgrade of the chiller plant.  Chillers have a 15-20 year lifespan, although they generally have been superseded in terms of efficiency well before the end of their operational life.  Replacement of chillers is best undertaken in winter.
Upgrade of FCUs.  Ageing FCUs can be replaced by modern units that are quieter, more energy-efficient and more reliable.
Control improvements can be implemented with the tenants in-situ

Applicable buildings

FCUs are found as a secondary HVAC system in most building types but are less common as a primary HVAC system type, except in shopping centers and smaller offices.

Floor plate implications

FCUs are typically ceiling-mounted and thus do not take up floor space.  The positioning of existing FCUs may adversely affect the subdivision of space. Units can, however, be moved and/or supplemented to accommodate different floor space configurations.

Temperature control / Occupant comfort

FCUs are generally considered a lower grade solution for office air-conditioning due to fan noise.  They can deliver good control when well maintained but the small zone size and high component count often lead to occupant discomfort.

Maintenance implications

FCUs are simple to operate and are relatively straightforward to maintain, but the components that require most maintenance – the temperature controllers and the valves – are in the occupied space and therefore maintenance can be intrusive.

Identification

An FCU will typically be installed in the cavity above a ceiling. The visible parts will be either a pair of supply and extract grilles, or a ceiling cassette.  FCUs may also be found mounted on the wall, on the ground, or occasionally in a floor void. Maintenance or operational staff will be able to advise whether a building uses FCUs.
