Trane Building Services • Bangalore, India
Guest Comfort and 24/7 Reliability
Le Meridien is an international five star hotel situated in the heart of Bangalore city. Brand Le Meridien epitomizes luxury and upscale full-service hotels and yet it is conscious of its environmental footprint.
Challenge
The hotel wanted to upgrade its HVAC system from reciprocating chillers which were installed in 1985. The aim was to improve energy efficiency, ensure reliability and reduce service costs.
Solution
Trane proposed and installed Series R™ helical rotary chillers in 1996, resulting in energy savings of nearly 30 percent. Satisfied with the chiller performance, the hotel engineering team ordered a Trane Tracer Summit™ building automation system. The building management system ensured that the chiller plant provided the appropriate capacity while minimizing energy consumption. By controlling the system throughout the day, comfort conditions were maintained when the building was occupied and energy consumption was minimized when occupancy levels were low. The Tracer Summit™ system allows the operator to change set points, schedules and other parameters through a PC workstation. Above all, it ensures single source responsibility for the complete HVAC system.
Results
By partnering with Trane, Le Meridien achieved superior energy savings, guest comfort and 24/7 reliability. The Tracer Summit system provides additional energy savings of six to eight percent as the chiller control program load cycling is designed specifically for optimum operation of plant. Different chilled water set points can be assigned during the plant operation cycle. The hotel, conscious of its substantial investment, also purchased a maintenance contract from Trane. Planned maintenance ensures that systems run at top efficiency and provide significant energy savings, which in turn leads to reduced carbon dioxide emissions. Trane also inspected the chiller heat exchanger tubes using eddy current testing to find and repair any erosion or corrosion, keeping the heat exchangers operating at peak efficiency and reliability.
“Trane’s excellent after-sales service guarantees no downtime, which helps me to run the business most profitably,” said Mr. G. Vijay, Vice President. He added, “When a guest walks in from outside and into the hotel, it’s a completely different atmosphere. We pay a lot of attention to temperature levels and fresh air in the hotel.”
