The Cliff House Hotel

5 Star Hotel Ardmore Co. Waterford

Case Study

The 5 star Cliff House Hotel in Ardmore was never going to be an ordinary hotel, so when it came to the design and installation of the heating and cooling system for the entire hotel including the bedrooms, the brief was that the system would be highly efficient, innocuous and quiet in operation.

The complete installation consists of 10 number R2 City Multi outdoor air cooled condensing units, with 75 number indoor DX fancoils. The majority of the indoors were low height ceiling concealed ducted units which are specifically designed for use in hotel bedrooms with 4kW of heating available, serving the guest bedrooms, with a height of only 200mm and sound power levels of only 24dBA ensuring that the bedrooms of the Cliff House Hotel are truly a place of tranquility.

Cliff House Hotel Testimonial

Frank Roche Services installed the complete heating and cooling system in the Hotel in 2008 when it was built.
We have ceiling concealed ducted units in all of our Bedrooms which are very discreet and quiet this is important to us for our Guests enjoyment of their room as we did not want our air conditioning system to be audible or visible.
Our IT Rooms are catered for using Hi-Wall units to control the temperature in the server rooms and reliability is a key requirement as they are on 24/7 and the Mitsubishi Units have more than proven themselves in this regard.
Since the installation of the unit by Noel and his crew we have Frank Roche Services maintaining the air conditioning system and are more than extremely happy with the service they provide due to their service engineer Gavin’s ability to be discreet while working in a live Hotel and it is reassuring to know that if we have to call on their service department that they are available on a 24 hour basis to answer any quires we have.

Fels Point Hotel, Tralee, Co. Kerry

166 bedrooms fully air conditioned, conference rooms, offices and open plan areas. This was achieved by installing 15 no City Multi R2 air conditioning systems. The City Multi R2 systems has the ability to provide simultaneous heating and cooling. Mitsubishi Electric’s heat recovery technology can result in substantial savings on running costs, for e.g one half of the hotel has excessive heat gain as it is facing the sun, so it needs cooling while the opposite side of the hotel needs heating as it does not have solar gain. Mitsubishi Electrics heat recovery system absorbs the heat from the solar gain area and transfers it to the colder side of the hotel which requires heating, thus providing free heat to that side of the hotel.

We also supplied and installed a complete controls package within our system, this comprised of 5 no G-50 centralised master controllers, a dedicated computer with
TG-2000 software to oversee all air conditioning units control and operation.
We also installed 2no PLC’s ( Programmable Logical Controllers) these prevent the air con units from being turned on,and left on all day and night while the room is not being occupied. The PLC’s also make sure the bedrooms are kept at a comfortable temperature never allowing the room go below 13° or above 29°.

With these systems and controls package it ensures absolutely no waste from the air conditioning systems and the systems run at maximum efficiency.

Musgraves, Tramore Rd., Cork

We installed 5 no PQRY-P500YSGM-A water condensing units. These water based systems have double the heat recovery potential, making these systems extremely efficient and economical. Not only do these systems produce heat recovery from indoor units on the same refrigerant circuit but it also produces heat recovery via the water circuit. The heat recovered from the a/c units on cooling is used to for hot water in taps, low temperature radiators etc.

In this project we supplied and installed 53 no indoor units which comprised primarily of concealed ducted indoor units, 4 way blow ceiling mounted cassettes and wall mounted units. Each indoor unit came complete with an individual remote controller which allows full control of that unit including the mode ( heating, cooling, fan or dehumidify), the temperature and fan speed can also be changed. We installed 2no G-50 master centralized controllers, where all indoor units can be monitored and controlled including 7day timer, auto on/off, indoor unit mode, temperature and fan speed.

We also supplied and installed 2no Procon interface sytems, to further existing control and ensure maximum efficiency is achieved throughout each system. These Procons interface all of our Mitsubishi Electric air conditioning units with Musgraves BMS
