Summary

The article describes the retrofitting of the "Watergate" building, on the banks of the Potomac, to transform it to essentially an office building, which would satisfy the conditions for class-A buildings in Washington. In particular, the air-conditioning system was completely changed. Because of space problems, the volume of new equipment was limited, particularly air ducts. The authors explain why a cold-air plant was chosen, which supplies air at 10 deg C to each locality. The plant and its various components are described, including the new plant for glycol-water cooling to -1 deg C, using screw compressors. This replaced a plant which produced iced water at 7 deg C which is now inadequate. Whenever condition permit, this plant uses external cold air, and it is possible to control the mass flow rate entering the buildings (variable flow rate).
