and a minimal outdoor air connection to maintain
collection requirements. Fan systems all consist of fanarray systems to provide the museum with redundancy
in the ventilation systems, while also being efficient and
quiet. A separate duct-mounted relief fan maintains
critical gallery pressurization.
B. Water-cooled centrifugal chillers-Three highefficiency, frictionless centrifugal chillers with low turn
down provide chilled water to building systems through
primary, variable-speed, chilled-water pumping for
reliable and energy-efficient operation.
C. Condensing boilers-Two high-efficiency condensing boilers serve the air-handling unit heating coils,
reheat coils, and perimeter heating units, such as
cabinet unit heaters and fin-tube radiation. All coils

and terminal equipment are selected at 100°F (38°C)
return-water temperature to maximize boiler system
efficiency.
D. Heat recovery chiller-A modular, water-cooled
heat-recovery chiller provides base-load chilled-water
and reheat-load hot water. The unit is sized to maximize
energy-efficient design, as well as serve as a redundant
cooling plant module and additional heating system fuel
type.
E. Fluid coolers-Four high-efficiency fluid coolers
meet project heat-rejection, energy-efficiency, and
critical-redundancy needs. Units are low-profile units
with energy-efficient acoustical fans and freeze protection systems for continual, year-round operation during
severe weather.
