New Trane VAV terminals, a Tracer Summit™ chiller plant management
system and a Series R™ chiller improve comfort and efficiency at Lakeview Hospital.
In the summer of 2007 Lakeview Hospital had a variety of comfort and HVAC system control
issues, plus the highest energy costs per square foot of any facility in the Mountainstar
Healthcare Network. By 2008 Lakeview Hospital’s chillers and aging pneumatic control
system were no longer able to provide the kind of temperature control needed for patient
comfort and required in the operating rooms.
Trane assembled a team of sales engineers and technicians who developed a comprehensive
plan to install new Trane VAV (variable air volume) terminals on the hospital’s upper floor
and operating rooms. The new air distribution system included Trane slot diffusers and variable
frequency drives installed on the air handlers. The Tracer Summit™ control system also serves
the upper floors and operating rooms.
In 2009 Craig Harris, Director of Facilities at Lakeview Hospital, determined that one of the
hospital’s existing 200-ton chillers was beyond repair and needed replacement. Trane was
awarded the contract and replaced the chiller with a new Trane RTHD Series R™ chiller that
consumes only .55 kW per ton of chiller capacity at full load. Trane also replaced the cooling
tower with a new Evapco unit and added a Tracer Summit chiller plant control system.
The air handling and controls upgrade, and the chiller and cooling tower replacement projects,
were completed on time. As a result, the hospital patients and staff enjoy improved
comfort while the hospital saves energy and maintenance costs.
Craig Harris said, “Mario Maestas, Trane account manager, and his team at Trane did a great job
on the chiller and cooling tower replacement projects. I was very impressed. They are very
good to work with and do a great job.
“The chiller plant is running very well now and we have the new Trane chiller to assure that the
hospital stays comfortable. We are seeing energy savings right off the bat--about ten
percent. That should improve as we add more variable frequency drives.”
Harris also cites the advantages of the Trane Tracer Summit™ system controlling the chiller
plant, cooling tower and HVAC system for best comfort and efficiency. “We set up the whole
system on the Tracer Summit system and that is working just great.”
