Central Water-Cooled Chill Water Plant
Zusammenfassung
A medical device facility in the island
needs to determine the feasibility of replacing the
existing air-cooled chilled water system at their
main plant with a more efficient water-system in
order to reduce the electric energy consumption and
realize the associated economies and reductions in
air emissions. As part of this effort, monitoring
equipment was installed on the existing chilled water
distribution system and the data obtained was used
to establish the annual cooling requirements and
energy and water consumption for the alternate
schemes under consideration. Two schemes will be
developed for cost estimating and life cycle cost
evaluation. One scheme was selected based on
availability of used equipment from a recently closed
nearby manufacturing facility as a secondary system
for redundancy interconnected to a completely new
system. The other scheme is based on keeping the
existing equipment and replaced as time requires. A
Life Cycle Cost Analysis for the both alternates over
a 20 year period will be performed under a discount
rate and energy cost scenario. The analysis will also
include air emissions levels of CO2, SO2 and NOx for
the different alternates for the average US location.
