A sustainable fan coil solution at Bank Centre
Keane Environmental supplied Diff usion fan coils units to the Bank Centre site in Ballsbridge, Dublin. The Bank Centre site was redeveloped with the campus designed to be a state-of-the-art work environment and one of the most sustainable workspaces in Europe.
All of the Highline models have been confi gured to perform effi ciently against external
system static pressures up to 50 Pa.
T
he project team included stakeholders from BKD Architects who designed the project along with consulting engineers Baker O’Reilly, Contractors Temec, with
Construction by Walls Construction. Diff usion’s slimline fan coil units were specifi ed for the project to ensure the client could make the best use of the original fl oor to ceiling heights while providing a comfortable, practical thermal environment. Located in the heart of Ballsbridge, Dublin 4, the project involved the complete refurbishment of the Bank Centre. Diff usion’s Slimline Highline 170 EC/DC ceiling mounted fan coil units with inlet attenuators were selected for the Bank Centre, to ensure that the maximum fl oor to ceiling height remained available. The industrial style of the refurbishment meant services were left visible making the Diff usion fan coil units ideal for the project.
Designed with aesthetics in mind, Diff usion’s Slimline 170 EC/ DC ceiling mounted fan coil units are an attractive solution for architects designing buildings with an industrial look, as the units can be ceiling exposed, as well as ceiling concealed. The units can also be powder coated to suit the colour requirements set out by the architects. The fan coil units (like all Diff usion fan coil units) have been designed and built to last. As a result, core
components are easily accessed and maintained and so if in future maintenance is required, coils and fans can be replaced without needing to replace the entire unit. This feature has the additional benefi t of ensuring the fan coil units are future proofed for updates in technology going forward. The Slimline Highline 170 EC/DC WH is a horizontally-mounted fan coil unit. The Diff usion Highline ranges of waterside control fan coils have been specifi cally designed with consideration to their intended installation. At only 170mm deep the slim fan coil unit is ideal for ceiling mounted or fl oor void applications. The Slimline fan coil is fi tted with high effi ciency EC/DC motors, off ering specifi c fan powers (SFP) between 0.19 – 0.43 W/l/s. All of the Highline models have been confi gured to perform effi ciently against external system static pressures up to 50 Pa. Flexibility of design allows the Slimline Highline range to be confi gured to suit a variety of installation requirements; including circular, rectangular and bulkhead ducted connections. The numerous models within the Highline range enable performance selections ranging from NR25 to NR40, and air volumes up to 700l/s. The robust fan coil chassis is manufactured from heavy gauge galvanised mild steel sheet, with burr free edges and a natural fi nish, formed and strengthened to provide a rigid and distortion free construction. Units have reinforced mounting points incorporated within the overall chassis width to facilitate drop rod installation. Full width removable maintenance panels are fi tted to provide access to key internal components for easy maintenance.
The Slimline fan coils feature single inlet, single width,
direct driven, centrifugal fans. Scrolls are manufactured from galvanised mild steel, complete with forward curved multi- bladed aluminium or galvanized steel impellers. The EC/DC motors are rated for continuous operation with inbuilt overload protection devices, and are capable of performance control via a 0 to 10 Volt dc signal. The fan coil unit’s heat exchangers are designed to achieve optimum heating and cooling performance using the industry predominant hot water and chilled water temperatures. The fan coil range can be supplied with either the Diff usion lifetime ‘Eco’ wire mesh fi lter, this option provides a robust environmentally conscious solution that can be vacuum cleaned in situ, or alternatively ISO grade media fi lters. Inlet and discharge attenuator options are available.
