International Cooling Projects Focus on Series Chiller Plant Design: Changes in chiller technology make series chillers cost-effective, energy-efficient alternative

摘要

It was once unthinkable that an entire city could be served by one enormous cooling plant. Over the past five years, dramatic increases in the number and size of district cooling projects are changing how we think. This trend is especially visible as new infrastructure is constructed in the Middle East and Asia, with brand-new cooling plants in excess of 50,000 tons. District cooling providers must find ways to distribute chilled water over long distances and to manufacture and deliver ton-hours as inexpensively as possible. The challenges of district cooling in extremely hot and humid weather locations, equipment capability improvements, and the economics of super-sized district cooling projects are creating a resurgence in series chiller plants.
