Refrigeration Plant Expansion
Government Facility - Washington, DC

The Power Plant provides chilled water and steam to several government buildings.  Ross Infrastructure (RI) has developed independent chilled water, steam, and cogeneration master plans for the facility and its associated distribution systems.

The Refrigeration Plant Expansion was a renovation project that included the addition of three (3) 5,400 ton chillers, primary/secondary chilled water pumping systems, new electrical gear, and new state-of-the-art distributed control systems for both steam and chilled water.  A new building to house the equipment was constructed adjacent to the existing Refrigeration Plant.  The cost to construct the new plant was $72,000,000.

  
Ross Infrastructure provided design oversight of all plant projects.  Detailed design was provided for 6,000 tons of chilled water in the existing Refrigeration Plant, two new deaerators, and miscellaneous improvements to the steam generating system.  A new Distributed Control System (DCS) was designed to control all functions associated with the new chilled water plant and its interconnection to the existing Refrigeration Plant.  The DCS will also provide control of seven (7) boilers with a total generating capacity of 620,000 pounds per hour (pph).  The DCS is designed to be redundant to provide uninterrupted control to various items within both the steam and chilled water plant. 

Ross Infrastructure also provided on-site Construction Administration, Commissioning, and Operator Training for the expansion.
