Chilled Water:

The Principals of RI have experience in the planning, design, and construction of some of the largest chilled water plants within the country.  Several of our Principals were key management personnel for a recently constructed $90 million project to install and operate an additional 65,000 tons of chilled water generation to the existing central chilled water plant at the National Institutes of Health’s Bethesda campus. 

Our staff’s experience in both design and operation of chilled water systems provides the understanding to apply both theoretical and field tested applications to various situations. 

One recent example required the interconnection between multiple chilled water plants.  Most of these interconnected chilled water systems have serious operational problems because multiple variable flow devices at different locations are being controlled from a common (differential pressure) sensor(s).  With this traditional approach, it is impossible to load plants independently and not avoid flow deficiencies within the system.  An approach that the Principals of RI has successfully employed on past projects is to establish any one of the plants as the “base” with the other plant as the “variable” flow generator.
