Evaluation of Chilled Water Distribution Systems on Manufacturing Campus

Evaluation of large chilled water and glycol/water (low temperature) distribution systems at a manufacturer’s campus. The chilled water system had an aggregate capacity in excess of 20,000 tons of refrigeration effect and the glycol/water (34F) system capacity was approximately 3,000 tons. These chilled water systems and the miles of piping they included served several hundred air handling units ranging to 100,000 CFM in capacity. The systems were incapable of efficiently delivering chilled water to all of the terminal devices and the operating costs were beyond norms for systems of this type. ACS supervised the quantitative analysis of these systems utilizing computer simulation techniques and prepared a report providing prioritized retrofit recommendations to the owner. This report was later used as the basis for design of retrofit of the central plant and the piping distribution systems by Acorn Consulting.
