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.
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.
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.
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.”
