The visually stunning Sofitel Hotel, Heathrow, opened recently and imaginatively connected by link-bridge directly to the new airport Terminal 5; is a £180 million joint venture between Sofitel and Arora Hotels, boasts 5 star status and is also the largest luxury airport hotel and convention centre in Europe.
All 600 of the superbly appointed hotel guest bedrooms, 41 meeting rooms, reception, conference hall, cinema and business centre etc, are supplied with air conditioning via 637 Athena and 160 Titan 4 pipe fan coil units, manufactured by Ability Projects Ltd, Wimborne, Dorset.
The Athena units are purpose designed for hotel installation and offer capacities of 2.3kW (cooling) and 1.5kW (heating). Located mainly within bulkheads above the room entry doors, they are fitted with stainless steel condensate trays, customised rearward facing coil tails, extended drip trays to shield valves during transportation and installation and supply and return air sensors. They also feature discharge plenums with foam acoustic baffles to limit fresh air inlet noise to NR29, 125mm fresh air spigots on the plenum side and flying power leads to assist installation.
The 1.2kW to 2.5kW nominal cooling and heating capacity Titan fan coil units, more or less standard and installed within the meeting rooms and other public areas, are designed to meet NR30 noise requirements, except in the bedroom floor corridors (NR35).
Installation of the Ability fan coil units was carried out by project mechanical and electrical contractors, Crown House Technologies, Dartford, Kent.
