High Marks for Chilled-Water System: Princeton upgrades and expands

摘要

Princeton University is proactively working to overcome its chilled-water system limitations - tonnage, flow, Delta T - with a comprehensive plan of attack that encompasses the central plant, distribution network and local buildings. Typically, efforts to deal with chilled-water limitations are undertaken in isolation, which can reduce the overall value of each individual change. By studying overall system impact, Princeton is able to maximize the cost-effectiveness of each change. Already, before the University has installed any new chillers, pumps, towers or a thermal storage tank, the upgrades have increased the capacity of the existing central plant by 1,000 tons. The plant operates using real-time economic dispatch based on the best predictive model - not conventional wisdom. The comprehensive upgrade program strongly positions Princeton for significant campus growth with an efficient, reliable and cost-effective operation.
