Old gear gets the boot to secure capital for upgrade
MECHANICAL SERVICES IS RARELY THE FOCUS OF A SUCCESSFUL HOTEL, ITS ALL ABOUT THE CUSTOMER- FACING FACILITIES SUCH AS BEDROOMS, FITTINGS AND SERVICES THAT ATTRACT ALL THE ATTENTION.
NOT SURPRISINGLY THAT is where money is spent so getting capital for mechanical services is never easy even at a landmark hotel like the Four Seasons in Sydney.
Built in 1981, the Four Seasons Hotel in Syd- ney has been a long standing attraction for visi- tors to Australia.
Its popularity has little to do with back-of- house facilities which is why it was a challenge for the hotel's operations director to convince the management team to allocate at least $2 million for a HVAC upgrade.
This included replacement of the hotel’s two chillers and two condensing boilers, installa- tion of energy meters, a new BMS and condens- er water system and new cooling towers.
To secure funding, the solution came in the form of a Build, Own, Operate and Transfer (BOOT) scheme that included purpose-built en- ergy efficient equipment and systems.
The 12-year contract included the design and delivery of a facility upgrade, including the installation of two 900kW Quantum chill- ers, and ongoing operation with full equip- ment warranty, delivering 100% operational availability and guaranteed energy savings to the client.
The upgrade equipment included two 900kW Quantum Chillers utilizing magnetic bearing, oil-free Turbocor compressors.
The two chillers were reportedly the world’s first magnetic bearing screw chillers of this ca- pacity and length to be loaded via a goods lift.
Both chillers were designed with a vessel length of only 1.9m, with typical equivalent chillers taking up a length of 2.4m.
OEM-trained ENGIE technicians assembled the equipment, which was transported 35
