Single FCU can give five spaces separate control
Ability Projects’ Multi-Room unit is a fan-coil unit that can serve up to five small spaces or offices and meet their individual requirements, rather than having five separate FCUs. These units are conventional ‘draw-through’ units with separate fans and motors serving a single plenum section and delivering the required volume of air to the space they serve.
A Multi-Room unit has one coil, one set of water valves and one controller. A unit serving five spaces is said to cost 65% less than five separate units, with a potential 80% reduction in pipe runs. There are additional savings in fittings and commissioning.
If one or more of the spaces has a requirement for cooling, the space with the largest cooling differential becomes the primary cooling space. The air volume to the other spaces is varied as required or pulsed on and off if only a small airflow is needed. When the primary space is satisfied, another area becomes the primary space.
