Series-Series Counterflow for Central Chilled Water Plants

When a project is large enough to justify the evaluation of several prospective designs, engineers are more willing to explore new solutions to familiar challenges. Setting aside convention enables ideas to flow freely. The viability of prospective solutions can then be gauged using criteria such as life-cycle cost, simplicity, and first cost. The scale of a new central cooling plant located in Washington, D.C. was large enough to warrant this type of innovative engineering. Given the magnitude of the project, the owner elected to outsource the design, construction, and operation of the 10,500-ton (36 900 kW) chilled water plant to an energy service company.
