Fan coil evolution - quietly combining compact with powerful

fan coil evolution

Commercial requirements often create conflicting design needs, especially when providing the building’s energy demand. This is no different for fan coil units, with space, noise levels and efficiencies seemingly a trade-off – until now.

Commercial projects such as hotels and offices often make use of fan coil technology to provide space heating and/or cooling. As the industry evolved, fan coils units changed too – introducing smarter controls and more efficient components to meet new requirements.

However, a by-product of aiming for lower running costs is often an increase in capital expenditure. As we move towards nearly zero energy buildings (NZEBs) at the end of 2020, there will be a legal requirement for all new buildings to use less power – which, it is feared, will only add to this issue.

The challenges of 2020 aside, there is a greater need for fan coil systems to adapt to changing commercial building trends. There is also an increasing demand for large open-plan areas combined with smaller collaborative spaces – yet there is also an expectation of higher efficiencies and lower noise levels.

These requirements – space, efficiency and noise – are often at odds with each other. For example, a lower noise rating requires a unit increase in size to utilise more fans, which can run more slowly and, therefore, quieter. Another solution for a quieter unit is to increase the casing to allow for inlet and or discharge attenuation – but, again, this increases the size of the fan coil, and additional cost.

In the search for energy efficiency, plant technology is increasingly running at temperatures closer to ambient, decreasing the system network losses. Although positive for building efficiency, this does mean that compatible fan coils require more airflow over the coil to produce the specified water to air thermal transfer, leading to larger units.

It is these conflicts that led UK fan coil manufacturer Ability to create a new evolution of fan coil design – one which takes these modern requirements into consideration from the start, rather than as costed changes to existing solutions. This solution reduces compromise to create a compact, powerful, yet quiet, fan coil unit: the EVO270 Plus Range.

 

The defining factor in where the three variables of size, noise and output meet is defined by the design of the fan. By taking an innovative new approach to this design, Ability has been able to produce a unit that can move more air for a given size – without an increase in noise output. As size is a critical factor in cost, building designers are now offered a solution with the above advantages at a lower cost to existing solutions.

The EVO270 Plus has already been successfully specified in multiple different commercial applications, offering high outputs and lower noise levels within a compact case size.
