Natural water from a well / aquafer under the hotel provides
100% free cooling for all the air conditioning without the use of heat-pumps or chillers
Quick stats:
- A 1970s office building with a Georgian façade was converted to a 150-bedroom, 4-star hotel
- The size of the building is approx. 6,000 m²
- Air conditioning is provided via free cooling from a well and without refrigerants
- There are very low CO2 emissions from the heating ventilation and air conditioning (HVAC) systems
- Because of the energy efficient design and the technologies used, the project qualified for an EXCEED grant from SEAI.

Entropic selected and supplied Fan Coil Units
Casing
Made of galvanized steel, thickness 1 mm, with inside thermal insulation (closed cell polyethelene 6 mm thick) and outside anticondensate lining.
Diffuser with intake grille
In prepainted metal sheet in the colour RAL 9003 with hinged intake grille that can be opened for inspection and maintenance of the air filter.
Air filter
Polypropylene cellular fabric regenerating filter.
Fan assembly
The fans have aluminium or plastic material blades directly keyed on the motor with double aspiration and they are dynamically and statically balanced during manufacture in order to have an extremely quiet operation.
Electric motor
BLAC three phase permanent magnet DC brushless sensorless electronic motor controlled with current reconstructed according to a sinusoidal wave by an inverter board single-phase 220-240 V, 50-60 Hz.
Heat exchange coil
It is manufactured from drawn copper tube and the aluminium fins are mechanically bonded onto the tube by an expansion process.The coil has two 1/2 inch BSP internal connections and 1/8 inch BSP air vent and drain.
Condensate collection tray
Made from plastic with an “L”-shape fitted on the inner casing. The outside diameter of the condensate discharge pipe is 15mm.
Round diffuser
The Carisma Coanda one-way cassette units are fitted with round diffusers designed to generate an airflow with “coanda” effect. The direction of diffuser outflow can be changed on site.
