Ability’s Multi-Room fan coils are perfect for projects where space is at a premium. In a residential environment, fan coil solutions can deliver high cooling outputs and provide a level of air circulation while remaining acceptably quiet.
The multiple units most residences need can often be difficult to position, particularly where space is limited and when the aesthetics of the apartment have to take a high priority. Ability’s Multi-Room fan coil solves these problems and are able to condition up to four individual spaces with a single unit and a clever controlling strategy.
Quiet and ‘Eco-friendly’
With extensive in-house testing, Ability units have always performed well in terms of acousticsand these Multi-Room units are no exception providing quiet operation. VAV (variable air volume) strategies mean that the fan coils only ever operate at design speedwhen the unit is trying to achieve the full design load. As the full design load is generally only required at some point during the day, the fan coil will only be at design speed at that time. At night and using the VAV strategy, the fan coil will be operating at a far lower and far quieter speed.Lower speeds not only mean low noise levels, they mean lower energy bills. A 70% set back fan speed saves approximately 50% of the electrical consumption of the fan motors.
How does Multi-Room work?
The Multi-Room unit controller interrogates all the spaces and assigns a priority space. This priority space will invariably be the room that is furthest from it’s set-point with a cooling demand. With the unit in cooling mode, the priority space then gets full design air volume with other cooling requirements getting proportionately only the air volume they need to satisfy their lesser requirements. Any space that requires heating at the same time gets no air delivered.
Once the cooling demands have been satisfied, if there is still a need for a little heating then the process temporarily reverses.
With these initial loads are dealt with, the Multi-Room units settles into a subtle blending of air flows to continue to maintain the individual space temperature requirements.
The most popular method of scheduling Multi-Room is our full colour 7” touch screen. If required, it is also able to act as a web portal allowing remote access from anywhere in the world!
At the other end of the scale, a Multi-Room unit can be switched on and off using a simple interposing relay, i.e. a central heating type programmer.
Multi-Room is just one application of our flexible Ability Fan Coil Ranges. These units are available in depths of 270, 235 and 190mm.
