Guests at the stylish and vibrant Ramada Encore London West hotel, opened recently in Chatham, can enjoy the pleasure of air conditioned bedrooms provided by purpose designed fan coil systems manufactured by Ability Projects Ltd, Wimborne, Dorset.
The hotel, based on a simple concept combining an upbeat atmosphere with comfortable contemporary accommodation, is ideally located adjacent to the historic Chatham Maritime Dockyard and has 90 bright, airy and spacious twin, double and family bedrooms fitted with Ability Aurora II fan coil systems, installed by Tandy Engineering Services Ltd, Gloucester.
Aurora II is in fact, the product of a detailed study of modern hotel air conditioning performance, installation and commissioning requirements and was carried out jointly by Ability Projects, Tandy and Siemens Building Technologies. The study observes that hotel bedroom air conditioning is characterised by short term cooling and heating cycles, which render the extensive operational capabilities of 4 pipe fan coil systems largely redundant.
Ability has overcome this problem by means of a control integrated, 2 pipe changeover fan coil unit, installed in the bulkhead above the guest room doors, fitted with electric heating and supplied with chilled or LPHW via a heat pump chiller on a seasonal basis as necessary. A heat sensor fitted to the flow side of the fan coil senses the water temperature and closes or opens the unit’s flow valve in order to activate heating or cooling cycles respectively.
The fan coil unit is regulated by a wall mounted Siemens LCD room temperature controller, which monitors and adjusts room temperatures during cooling and heating cycles, initiates automatic changeover and switches the electric heater and 3 speed fan throughout normal, energy saving and standby operating modes. The controller’s minimum set point initiates fan coil start up at room temperature of 160C and also allows occupants to set fan speeds and temperature to their requirements.
Aurora fan coil units at the Ramada Encore Chatham measure just 755mm long by 516mm wide and 235mm deep with capacities of 1.3kW cooling and operating noise levels of NR30 during the day and NR25 at night.
Special features include a control enclosure with access from below and rear facing pipe connections – important considerations in hotel fan coil installations – and discharge plenums with spigots sized to connect direct to the bedroom discharge grilles.
Standard Aurora options relevant to hotel applications include quick connection waterside flexible hoses, fully integrated commissioning packages and energy efficient fan/motor combinations that offer the facility of remote and step less fan speed control. The remote control system can be interfaced with a simple time clock, hotel booking system or even the room key card system.
