CHILLER PLANT AND DISTRIBUTION SYSTEM DESCRIPTION

The NSAA chiller plant and distribution system includes all mechanically and electrically interlocked ancillary parts, equipment and components required for safe and continuous operation of chilled water production, treatment, storage, and distribution including but not limited to: chillers, pumps, cooling towers, actuators, valves, controls, monitoring systems (to include computers, workstations, servers, and software), piping, insulation, chemical systems, ventilation and temperature control for plants.

The chiller plant and distribution system serve the United States Naval Academy by generating and distributing chilled water to approximately 33 facilities throughout Naval Support Activity Annapolis. There are two main chilled water plants (CHWPs). Both CHWPs utilize a closed loop system for operation. This system contains greater than 1.25 million gallons of chemically treated water maintained at 42 degrees Fahrenheit 24 hours per day, seven days per week. There is approximately 29,289 linear feet of piping within the closed loop consisting of approximately 29,289 linear feet of supply piping and approximately 29,289 linear feet of return piping.

The first chiller plant is located at USNA-590A and is also known as the Rickover Plant or “Old 572U”. This plant has a total rated capacity of 5,000 tons. This capacity is spread across (2) 1,250-ton & (1) 2,500-ton centrifugal chillers. Two 1,250-ton chillers in 590A may be operated 24 hours per day, seven days per week. The 2,500-ton chiller in tandem with one 1,250-ton chiller is typically utilized when in summer/cooling season (usually March- November).

The second chiller plant is located at 597U and is also known as the LeJeune Plant or Chiller Plant II. This plant has a total rated capacity of 7,500 tons from three 2,500-ton centrifugal chillers. One 2,500-ton chiller in 597U may be operated 24 hours per day, seven days per week, 365 days a year. This plant acts in tandem with CHWP 590A during summer months to support an approximate yard cooling load of 8,500-10,000 tons.

Graphic overview documents expanding on chiller and EMCS utilities are also provided upon request as separate attachments after award. These documents are purely supplemental and diagrammatical in nature. They are not necessarily an accurate representation of the current system configuration but may assist in understanding the overall system.
